Chapter Summaries

Gu Xi met three former Mysterious Academy deans resurrected in the temple, who offered their help in exchange for professor positions and bodies. They advised him on how to secure authority and make his new department the academy’s First Department by choosing Summoning.

• Gu Xi entered the temple and met three bearded former deans who explained that the academy’s changed state had revived them.
• The three agreed to help Gu Xi establish a department in exchange for professor positions and bodies, abandoning their hopes of becoming deans or Department Heads again.
• The gray-bearded dean warned Gu Xi that Karimdo and the others might hide important authorities from him.
• The white-bearded dean with the pink bow revealed that departmental rankings depended on the academy’s style and professors’ Basic Skills, not student enrollment.
• The former deans advised Gu Xi to secure Summoning, which could make his new department the First Department and give him a chance to become the academy’s hidden Vice-Dean.

Gu Xi received advice from three former deans on preparing the name, treasure, and secret chamber for his new First Department, and learned about the academy’s powerful benefits for its leaders. He returned to his City Gates with the Giant Skeleton, where Amirka was suppressing a Bone Dragon.

• The three former deans helped Gu Xi plan the First Department and explained that its leaders gained enhanced combat power and boosts at certain level breakthroughs.
• Gu Xi promised to reserve professor positions for the three undead, then left the temple-like tomb, which vanished and left three tombstones behind.
• The Giant Skeleton followed Gu Xi as his subordinate, and Gu Xi noticed its bones had been strengthened by lightning elemental power.
• Gu Xi returned to the City Gates and found Amirka fighting a Bone Dragon larger than the Death Avatar.
• Amirka and the six Bone Dragons at the Main City Gate easily suppressed the Bone Dragon, which had flight but no other notable enhancements.

Gu Xi learned that a Bone Dragon Knight Hero had attacked his camp in several waves, then watched a Giant Skeleton destroy the latest attacker and perform a strange ritual. The Hero arrived on a powerful Ghost-like Bone Dragon and demanded Gu Xi’s Death Avatar, prompting Gu Xi to attack.

• Amirka told Gu Xi that a Bone Dragon Knight Hero had sent three waves of undead against the camp after demanding its Bone Dragons.
• The Giant Skeleton struck down the Giant Skeleton Dragon with lightning, beat it to pieces, and fused one of its teeth into his shoulder during a ritual.
• A large, mist-shrouded Bone Dragon carrying the armored Hero flew up to Gu Xi, and the Hero demanded the Death Avatar.
• Gu Xi refused and attacked with a Magic Arrow as the Death Avatar charged and unleashed its Death Dragon Breath.
• The Hero leaped onto the Death Avatar and pressed down on its neck to prevent it from breathing again.

Gu Xi and the Death Avatar killed Dragon Slayer Kargas, and the Bone Dragon that helped defeat him joined Gu Xi’s party as a Nether Soul Dragon. Gu Xi completed the High-level Undead task and obtained the Death Lord skill, completing the Three Divine Skills.

• The Death Avatar and its flame clone knocked Dragon Slayer Kargas from its back, tore off his arms, and burned him as he tried to escape.
• Kargas’s Bone Dragon tore his body in half, and the Death Avatar finished him with Dissolving Rays.
• The Bone Dragon submitted to Gu Xi, who accepted it into his party as the Nether Soul Dragon.
• Gu Xi completed the High-level Undead task and received the Necromancer class skill Death Lord.
• Gu Xi confirmed that Death Lord completed the Three Divine Skills.

After achieving the Three Divine Skills, Gu Xi planned his route through the academy and followed the Nether Soul Dragon to a former Dragon Breeding Ground. There he found a vast Dragon Tomb and discovered that the replica Sword of Leadership planted in its center was seven meters tall above the ground.

• Gu Xi studied his marked map and decided to visit Jason, then set out on the Evil Coffin with the Death Avatar, Giant Skeleton, and Nether Soul Dragon.
• The Nether Soul Dragon led Gu Xi down a side path scattered with fragments of large animal bones.
• Gu Xi followed the Nether Soul Dragon to a huge clearing filled with dragon skeletons and fossilized eggs, realizing it had once been the academy's Dragon Breeding Ground.
• The Nether Soul Dragon drew Gu Xi's attention to a replica Sword of Leadership planted in the clearing's center.
• Gu Xi approached the sword and discovered that the section above ground stood seven meters tall.

Gu Xi discovered a Space Pillar stabilizing the Mysterious Academy’s space while searching for the Dragon Tomb, and learned that dragon bones and energy-rich soil nearby could be harvested for Aryadovi City. After collecting the materials, he discussed the Space Pillar with Luna and heard that the Summoning Tower was ready and the city’s growth was progressing.

• Gu Xi found a warning that his silver Longsword was entering a Space Pillar’s suppression range, retreated, and learned from his notebook that the pillars stabilized the Mysterious Academy’s fused spaces.
• Gu Xi decided not to touch the Space Pillar and summoned the Main City Gate, sending the Ghost Squad to collect nearby dragon skeletons, Dragon Egg Fossils, and soil for Aryadovi City.
• Luna inspected the Space Pillar and told Gu Xi that it had pinned a giant beast beneath it, while Gu Xi compared it with a method that sealed a Great Lord inside a mirror image.
• Gu Xi recorded Luna’s observations and told her to reserve the dragon bones for a possible future Dragon Tomb; Luna reported that the Summoning Tower had been built and discussed plans to raise Aryadovi City’s level.
• The Ghost Squad cleared away the dragon bones and excavated the energy-rich soil, which Luna also wanted for Aryadovi City.

Gu Xi recruited Jason and several other undead while inspecting the Princess's Forest, building support for his plans to challenge Naweiduo's influence. After Shaya returned with intelligence about powerful neutral faculty and unclaimed buildings in Aryadovi City, Gu Xi noticed Isabella's name.

• Gu Xi found Zombie Jason in the Princess's Forest and persuaded him to join his team.
• Jason agreed to serve Gu Xi, who learned that Jason was a level 10 Veterinarian with powerful combat skills.
• With Jason's help, Gu Xi recruited nine undead across the nearby mountain peaks and stationed them around the area.
• Gu Xi's intelligent undead allies agreed to help find Naweiduo's subordinates in hopes of gaining positions and authority in the academy.
• Shaya returned with information about neutral faculty members and unclaimed buildings, and Gu Xi saw Isabella's name at the top of the list.

Gu Xi offered Isabella a place to preserve her husband’s body in his department’s secret chamber in exchange for her healing services. Isabella agreed to join his team as the chamber’s guardian while remaining the academy’s school doctor.

• Gu Xi reviewed Shaya’s intelligence about Isabella and learned she had stayed at the academy to gather special blood for her husband.
• Isabella treated Shaya and warned that her cursed blade was gradually damaging her foundation.
• Isabella asked Gu Xi for a haunted mansion where her husband could rest safely, explaining that she feared he would be lost if his body were exposed to blood.
• Gu Xi offered to let Isabella preserve her husband’s body in his department’s secret chamber, which would be protected by deathly aura and other safeguards.
• Isabella accepted the offer and agreed to provide treatment as the secret chamber’s guardian, and Gu Xi welcomed her to his team.

Gu Xi used the Map Carved on the Blade to open a secret chamber beneath Isabella’s pool, intending to make it the new department’s chamber. There he found Isabella’s husband alive and standing as the chamber’s guard.

• Gu Xi decided to place the secret chamber on Isabella’s grounds and gave her the knife to choose a location.
• Isabella led Gu Xi past Shaya’s Blood Cocoon to a pool of mercury and medicine that protected her husband.
• Gu Xi stabbed the knife into the railing, causing the pool to split and reveal stairs to a room below.
• Gu Xi descended with Isabella and found a Vampire guarding the secret chamber.
• Isabella rushed to the Vampire and exclaimed that he had stood up, while Gu Xi realized the task had made her husband the guard.

Gu Xi agreed to preserve Isabella’s secret chamber so her husband could continue living as its guardian, and arranged a believable rumor to protect it. After marking the chamber as his own and bringing over the Bloodstained Treasure Chest shell, he accepted Isabella’s healing clone as a companion.

• Isabella told Gu Xi that her husband could survive as the secret chamber’s guardian as long as the chamber and its treasure chest remained, and begged him not to finish the quest.
• Gu Xi agreed to leave the secret chamber in place and devised a rumor about a treasure chest whose quality improved over time and when people died nearby.
• Gu Xi used Karimdo’s key to mark the secret chamber as his, then left the blood cloud and opened the Main City Gate to receive the Bloodstained Treasure Chest shell.
• Undead from Aryadovi City delivered the chest shell, and Isabella offered Gu Xi a healing clone created from her Blood Holy Grail.
• Gu Xi accepted the Blood Clone and asked whether she could use his Healing Tent.

Gu Xi transformed the secret room into the Bloodless Chamber and secured its future activation under his authority at the academy. Isabella then offered to introduce him to ostracized undead faculty who could help him gain more positions, and marked their gathering places on a map.

• Gu Xi concealed the treasure chest behind the coffin and used Karimdo’s key and an incantation to reshape the secret room into the Bloodless Chamber.
• Gu Xi established a rule that the academy would prioritize activating the chamber if he held the department head position when it was re-established.
• Gu Xi gave Isabella the dagger key and entrusted her with guarding the secret room.
• Isabella offered to connect Gu Xi with undead faculty members who had died before the academy vanished and explained that they might help him gain authority.
• Isabella marked the remote gathering places of the undead faculty on a map for Gu Xi.

After recovering Shaya, Gu Xi sought out David, the academy’s Secret Passage Manager, to borrow his routes and learn how to arrange passages in a city. David opened the passages for Gu Xi and offered advice, but remained neutral and did not join his group.

• Shaya recovered from her injuries, though the double images caused by her blade remained, and she said she could fight with her eyes closed if needed.
• Shaya led Gu Xi to a statue where he summoned David, the Secret Passage Manager.
• Gu Xi showed David his department-head key and learned that only the academy’s outer secret passages still worked, though David expected to retain his authority when the new academy appeared.
• David agreed to open the passages for Gu Xi but refused to become one of his subordinates.
• Gu Xi asked how to connect the districts of his city, and David suggested turning its sewers and waterways into secret passages and carefully arranging hidden doors.

Gu Xi reached a hidden gathering place where former academy faculty had formed a marketplace, and recruited many of them by offering academy positions or work in Aryadovi City. He left after sending more than half the undead to his city, while the rest remained neutral and peaceful.

• Gu Xi recruited undead across the secret passages, raising his Death Lord level by one before reaching the gathering point with Shaya.
• The Old Man led Gu Xi to the edge of the secret passage and pointed him toward the gathering place.
• Gu Xi used Summoning at the barren site, revealing a tent marketplace filled with undead former faculty.
• Gu Xi offered the undead positions at the new academy or work in Aryadovi City, and many agreed to join him.
• Gu Xi sent more than half the undead to Aryadovi City within half an hour, while the rest remained neutral without opposing him.

Gu Xi prepared to challenge Karimdo for a place in the new academy, displaying his forces and claiming the First Department with the Six Paths of Reincarnation Disk Base. Karimdo realized Gu Xi was far more knowledgeable and prepared than he had assumed, just as the final battle was about to begin.

• Gu Xi spent three days completing his tasks and recruiting or befriending nearly every neutral Undead in the academy space.
• Gu Xi brought eleven heads of Naweiduo's staff members and pets to the Burial Ground, then set up three City Gates and a wall with his troops.
• Karimdo told Gu Xi to stay out of the battle and promised him a place in the new academy after Naweiduo was defeated.
• Gu Xi announced that he would compete for the First Department and presented the Six Paths of Reincarnation Disk Base as its treasure for teaching Summoning.
• Karimdo's smile vanished as he understood that Gu Xi was not the ignorant novice he had expected.

Gu Xi watched Karimdo and his companions confront Naweiduo, while preparing his own troops in case the fight spilled over. Naweiduo revealed a force of unusually numerous and monstrous Skeleton Behemoths, and Gu Xi ordered Amirka to ready for battle.

• Karimdo considered asking Gu Xi to help fight Naweiduo, but Gu Xi pointed to the heads he had brought, and Miranda and the others refused to intervene.
• Karimdo and his companions went to Naweiduo's Burial Ground, where Naweiduo's Giant Skeleton stood up and Naweiduo appeared atop its head.
• Gu Xi asked his Giant Skeleton to study the enemy's enhancements, then watched as Naweiduo cast a ring of thorns and summoned bizarre Skeleton Behemoths.
• Gu Xi noticed that Naweiduo had far more Skeleton Behemoths than expected and ordered Amirka to prepare the troops to attack if the enemy approached.

As Naweiduo and Karimdo’s battle spread across the hills, a Skeleton Behemoth charged toward Gu Xi’s City Gate, where Amirka led his troops out to destroy it. Amirka claimed a Skeleton Rhino as a mount, then returned to watch the increasingly wide-ranging duel between Naweiduo and Karimdo.

• Naweiduo’s Skeleton Behemoths broke Karimdo’s defensive line and dragged the battle beyond the Burial Ground.
• A Skeleton Behemoth charged toward Gu Xi’s City Gate after spotting the displayed heads of Naweiduo’s subordinates.
• Amirka led four Crimson Knights and the Gladiator Black Guards in a charge that brought down the Skeleton Behemoth.
• Amirka took the Skeleton Behemoth’s Rhino Horn, summoned a Skeleton Rhino, and rode it back to the City Gate after Gu Xi approved his share of the spoils.
• Gu Xi watched Naweiduo and Karimdo fight as their attacks spread farther across the battlefield.

Gu Xi watched Karimdo and Miranda struggle against Naweiduo while Kanaste maneuvered to protect his own forces. When they tried to redirect Naweiduo’s Giant Skeleton toward Gu Xi, he used his Steel City Gate and Earthbound Weird Dragon to intercept it, but the skeleton escaped the dragon’s coils and prepared to counterattack.

• Naweiduo suppressed Karimdo and Miranda as both held back, while Kanaste focused on fighting Naweiduo’s subordinates to preserve his forces.
• Karimdo and Miranda agreed to separate Naweiduo from his Giant Skeleton, and Miranda lured the skeleton toward Kanaste.
• Kanaste recognized Miranda’s plan and redirected the Giant Skeleton toward Gu Xi instead.
• Gu Xi stopped his own Giant Skeleton from engaging and turned the Steel City Gate toward the approaching enemy.
• The Earthbound Weird Dragon attacked the Giant Skeleton with Water Flow Dragon Breath, and their reflected physical attacks damaged the Steel City Gate.
• The Earthbound Weird Dragon tried to crush the Giant Skeleton in his coils, but the skeleton detached and reassembled outside them before seeking a counterattack.

Gu Xi helped defeat Naweiduo and watched Karimdo and Miranda begin rebuilding the Mysterious Academy. As Karimdo declared himself the new dean, Gu Xi cast Summoning on the reorganizing space to protect his claim.

• The Giant Skeleton charged the Steel City Gate, but Gu Xi summoned his Summoning Tower to smash its head and pin much of its body underground.
• Karimdo and Miranda attacked Naweiduo without the Giant Skeleton's support, and Karimdo severed Naweiduo's head before Miranda shattered it.
• Karimdo and Miranda combined their authority to form a sphere for rebuilding the Mysterious Academy, while Gu Xi climbed atop the Summoning Tower to watch them.
• Karimdo relinquished the Crocodile Academy's authority to become dean, and Miranda relinquished the Bat Academy's authority to become vice-dean.
• After the original academy's connection to the space was severed, a silver scepter descended toward Karimdo, and Gu Xi cast Summoning upon the space.

Gu Xi used Summoning to establish an undead style for the rebuilt academy before Karimdo could take control, then secured a Crow Department and its facilities. As the academy’s departments took shape and Karimdo approved building requests, authority gradually shifted into Gu Xi’s hands, and Gu Xi completed the long-term mission Light of the Mysterious Academy.

• Gu Xi used Summoning to make the academy’s scepter take the shape of a skull, locking the new academy into an undead style before Karimdo could change it.
• Miranda proposed a Bat Department, and Gu Xi established the Crow Department, teaching Summoning, with the Six Paths of Reincarnation Base as its treasure and a secret chamber underground.
• Karimdo appointed Kanaste to lead the Giant Bear Department, while Saint Portrait Ailas established the Weasel Department, completing the four major departments.
• The academy’s neutral staff retained their authority and sent Karimdo building requests, leaving him approving construction while authority increasingly passed to Gu Xi.
• Gu Xi received notice that the long-term mission Light of the Mysterious Academy was complete.

Gu Xi completed the Light of the Mysterious Academy mission and received the purple title of Crow Department Head, along with authority over 63% of the academy. He gained powerful Summoning bonuses and academy benefits, while the Crow Department's position as the academy's top department appeared secure.

• Gu Xi completed the rebuilding mission and received the Crow Department Head title and 63% of the academy's internal authority.
• Gu Xi equipped the Mysterious High-Level title, raising his Summoning to level 14 and granting it a 100% success rate, doubled by the title's special effect.
• Gu Xi learned that he would receive one-tenth of the Treasure Secret Chamber's contents each year while he remained Department Head.
• The Six Paths of Reincarnation Base was fully repaired, granting academy members Summoning and boosting the Crow Department's strength within the academy.
• Gu Xi concluded that the Six Paths of Reincarnation Base would secure the Crow Department's status as the academy's number one department.
