Chapter Summaries

As ghosts began attacking Room 402, Yang Jian concluded that staying inside was no longer safe and led the group out into the dark corridor. The chapter ended with everyone abandoning the room and following him.

• After the lights went out, Yang Jian and the others heard a ghost smashing against a wall and something running back and forth through the corridor.
• Yang Jian warned Liu Qingqing that he had considered killing her because of the supernatural items and ghosts connected to her, but agreed to postpone the matter until the delivery mission ended.
• Yang Jian saw that the corpse hanging from the light had moved outside their door, while the room's light dimmed and a ghost began breaking through the bathroom wall.
• Yang Jian opened Room 402's door and ordered everyone who wanted to live to follow him outside.
• Li Yang, Yang Xiaohua, and Wang Shan followed Yang Jian, and Old Eagle and Liu Qingqing eventually left the room as well.

Yang Jian led the group out of Room 402 after deducing that the fourth-floor lights attracted ghosts instead of protecting anyone. As a door-opening ghost descended a newly appeared staircase, Yang Jian extinguished the Ghost Candle and prepared to face it in the corridor.

• Yang Jian led Li Yang, Yang Xiaohua, Wang Shan, Old Eagle, and Liu Qingqing out of Room 402, avoiding muddy footprints that stopped at the doorway.
• The corpse, muddy footprints, and a ghost in the restroom remained inside Room 402, while Yang Jian used the Ghost Candle to gather and protect the group.
• Yang Jian explained that the fourth-floor lights drew ghosts toward illuminated rooms, and he suspected that other messengers were hiding in Rooms 401, 403, 404, and 405.
• The Ghost Candle began burning rapidly, and Yang Jian identified the approaching figure as the door-opening ghost that wandered the post office at night.
• Yang Jian blew out the Ghost Candle and told everyone to stand against the wall as the ghost walked toward them; he considered confronting it himself.

Yang Jian confronted the Door-Knocking Ghost as it began to reactivate the post office lights, and used the cursed cleaver to split its image in the medium. The lights exploded and the lethal rule was triggered, leaving Li Yang’s relit ghost candle as the group’s protection.

• Yang Jian told the others to stay against the wall and approached the ghost, which passed Old Eagle and Liu Qingqing without attacking them.
• The ghost raised its head toward a dead bulb, causing the light to gradually turn on and threatening to trigger its killing rule.
• Yang Jian struck the ghost with the coffin nail, but the supernatural influence remained, so he prepared to use the cursed cleaver.
• Yang Jian found the ghost among the former fourth-floor messengers in the medium and split its figure with the cleaver.
• The corridor lights exploded, triggering the ghost’s lethal rule, and Li Yang relit the ghost candle.

Yang Jian used his hatchet against the ghost, triggering a deadly lights-out curse that Li Yang's ghost candle barely resisted. With the ghost temporarily gone and Yang Jian wounded by the hatchet's curse, the group sought a safer room to survive the night.

• Yang Jian struck the ghost beside Wang Shan with his hatchet, causing the corridor lights to explode and the ghost to vanish.
• Li Yang's ghost candle burned rapidly to resist the lights-out killing rule, then slowed after it had apparently neutralized the attack.
• Yang Jian explained that the curse had been blocked, while the hatchet's curse split his body and ghost shadow; he chose not to use his reset ability.
• Yang Jian warned that the ghost could return and said the group needed a room where the lights would stay off, with Li Yang's Blocking Door ability offering protection.
• Yang Jian searched the eerie rooms with his Ghost Eye as the others waited for him to choose where they would go.

Yang Jian led the group into Room 404 to escape a ghost following them through the corridor, and Li Yang used his paranormal power to seal the bedroom door. The ghost remained outside, kicking the door before stopping to pace, leaving everyone sheltered but still in danger.

• Yang Jian led the group around Room 402 toward Room 404 as a ghost followed their footsteps, held back by the ghost candle.
• Yang Jian opened the bedroom door with his ghost shadow, and everyone entered before the mud-footprint ghost reached them.
• Li Yang sealed the bedroom door with Blocking Door's paranormal power, and Yang Xiaohua lit the room after the ghost candle burned out.
• The ghost kicked the door three times, but Li Yang held it shut; it then stopped kicking and paced outside.
• Liu Qingqing and Old Eagle acknowledged how dangerous the fourth floor was and said the messengers there were likely to die.

Yang Jian and the others found a concealed wardrobe in Room 404, where a hidden messenger attacked Liu Qingqing with a bloodstained mallet. Yang Jian dragged Qu Hongtao out and learned that two more people were hiding inside the apparently supernatural wardrobe.

• Yang Xiaohua voiced despair about surviving the night, and Yang Jian warned her that she had no right to give up.
• Wang Shan and the others discovered Zhu Lei’s decomposed corpse beneath a bed, and Old Eagle identified him and read his suicide note.
• Yang Jian noticed an unusual wardrobe and sent Liu Qingqing to investigate it.
• A hidden person struck Liu Qingqing’s head with a bloodstained wooden mallet, but Liu Qingqing survived because her body was a puppet.
• Yang Jian pinned an arm inside the wardrobe with his spear and dragged out Qu Hongtao, who said two other messengers were hiding with him.

Yang Jian confronted Liu Qingqing and the surviving fourth-floor couriers, then learned that Wang Feng possessed a bloodstained mallet capable of suppressing supernatural abilities. He demanded the mallet and advanced again, leaving the couriers on the verge of a fight.

• Liu Qingqing reassembled her damaged puppet body and demanded that Yang Jian kill Qu Hongtao, but Yang Jian refused and warned her not to challenge him.
• Yang Jian kicked Qu Hongtao into the wardrobe, prompting Wang Feng and another courier to emerge alongside him.
• Wang Feng revealed the bloodstained mallet, and Yang Jian tried to seize it; Wang Feng struck his ghost hand and temporarily numbed much of his body.
• Yang Jian slashed Wang Feng's arm with the cracked spear, and another courier blocked his ghost shadow with a supernatural zone.
• Yang Jian demanded that the couriers hand over the mallet or prove they could make him stop, then strode toward them again.

Yang Jian subdued Wang Feng and his companions, took the wooden mallet, and altered Wang Feng’s memories before letting them live. He gave the mallet to Li Yang and ordered the three messengers to remain in the room.

• Yang Jian attacked Wang Feng’s group again, using his ghost shadow to invade one messenger’s body and immobilize Wang Feng when he came to help.
• Yang Jian suppressed the first messenger’s ghost and searched Wang Feng’s memories, altering them while learning what he could about the wooden mallet.
• Wang Feng surrendered the wooden mallet and apologized, and Yang Jian released him and his companions.
• Yang Jian examined the mallet, found no information about its cost of use, and gave it to Li Yang as a team resource.
• Wang Feng asked to return to the wardrobe, but Yang Jian ordered him, Qu Hongtao, and their companion to stay in the room.

The people gathered in Room 404 waited through several quiet hours, believing the room had offered them shelter from the ghosts outside. When Wang Shan was found dead without warning, Yang Jian suspected that a ghost disguised as a fourth-floor messenger was among them, leaving everyone wary as the night continued.

• Yang Jian chose to wait until morning before settling scores with the people in the room, while everyone stayed alert against the ghost outside.
• After several peaceful hours, Yang Xiaohua discovered that Wang Shan had died, though he showed no obvious injuries or signs of supernatural erosion.
• Old Eagle examined Wang Shan and judged that he had died recently, while Liu Qingqing suggested a ghost had killed him.
• Yang Jian reminded everyone that a ghost had infiltrated the fourth-floor messengers and might be among them.
• Wang Feng and the others grew suspicious of one another, while Yang Jian predicted the ghost would keep killing if it found an opportunity.

After Wang Shan’s unexplained death, Yang Jian and the messengers in Room 404 suspected that the fourth-floor ghost was hiding among them. They chose to wait together despite their distrust, and the chapter ended with the ghost outside striking a door across the corridor.

• Yang Jian found no clue to Wang Shan’s death in the memories he stole from the corpse.
• Liu Qingqing accused the three messengers from the fourth floor of being the ghost, while Wang Feng and Qu Hongtao denied it.
• Yang Jian rejected the argument and threatened to kill everyone if they forced his hand, so the group agreed to wait in Room 404.
• Qu Hongtao considered hiding in the wardrobe, but Yang Jian warned he would kill him if he tried; Yang Xiaohua also abandoned her request to hide there.
• Midnight passed without another death, but the ghost outside began striking a door across the corridor.

A ghost killed Qu Hongtao in Room 404, and Wang Feng’s suspicions led Yang Jian to confront Old Eagle. Yang Jian revealed that the real ghost was inside Wang Shan’s corpse and pinned it with the cracked spear.

• A ghost kicked open Room 404’s door, but Old Eagle used his bone gun to repel it long enough for Li Yang to shut the door.
• Yang Jian saw Qu Hongtao die suddenly, though his Ghost Eye revealed no culprit.
• Wang Feng accused Old Eagle of being the ghost, citing his connection to Lin Yue and the direction Qu Hongtao had faced.
• Yang Jian approached Old Eagle with his spear, then instead drove it through Wang Shan’s corpse.
• Wang Shan’s corpse twitched and shrieked before the coffin nail suppressed the ghost inside it.

Yang Jian identified the ghost hidden in Wang Shan’s corpse and explained how it had secretly controlled him and killed messengers. The fourth floor’s immediate threat was exposed, but Yang Jian realized the Ghost Post Office itself might be releasing ghosts that undermined its own control.

• Yang Jian struck Wang Shan’s corpse with a coffin nail, causing it to twitch and scream, which revealed that the corpse was connected to the ghost.
• Yang Jian explained that the ghost had likely invaded Wang Shan after he reached the fourth floor and could conceal itself by controlling a messenger’s body.
• Yang Jian traced his suspicion to the door-opening ghost stopping beside Wang Shan and to Qu Hongtao’s gaze during the murder, concluding that the ghost had exposed its position.
• Yang Jian said Wang Shan’s death had been suspiciously silent and that the ghost could make people trigger its killing rule, though it could not attack freely like a Ghost Tamer.
• Yang Jian considered that the ghost might be the one Lin Yue had brought in and wondered whether the Ghost Post Office was fighting itself as dangers spread to the fifth floor.

Yang Jian and the surviving messengers made it through the night after he restrained the ghost inside Room 404. At dawn, a red letter drifted down to the fourth floor, offering the survivors a chance to advance, and Yang Jian prepared to deliver it and reach the fifth floor.

• Yang Jian kept watch over Wang Shan’s corpse and the restrained ghost while the other survivors rested through the remaining supernatural attacks.
• At six in the morning, the survivors left Room 404 and met Qin Kai and Da Qiang in the corridor.
• Old Eagle told Qin Kai and Da Qiang that Yang Jian had dealt with the ghost, though they doubted the claim.
• Liu Qingqing spotted a red letter tied to a balloon drifting down and stopping outside the fourth floor.
• Yang Jian recognized the letter as a chance to advance to the fifth floor and smiled.

Yang Jian claimed the red balloon and discovered that it could lift and suppress supernatural beings, then entrusted it to Yang Xiaohua. As the fourth-floor delivery mission began, strange instructions appeared on the corridor walls.

• Yang Jian claimed the red-envelope letter and red balloon, facing no challenge from the other mail carriers.
• When the balloon’s string fused to Yang Jian and lifted him and his ghost shadow into the air, he observed that it suppressed ghosts more strongly the higher it rose.
• Yang Jian cut the string to free himself, then had Yang Xiaohua test the balloon and confirmed it did not affect people without supernatural power.
• Yang Jian ordered Yang Xiaohua to keep the balloon safe, leaving Qin Kai and Da Qiang disappointed that they could not claim it.
• Paint peeled from the fourth-floor corridor walls, revealing four delivery mission instructions.

Yang Jian and the fourth-floor couriers learned that their red-letter delivery mission would take them aboard a supernatural bus to an old house in Dachang City. As the couriers prepared to leave, Da Qiang and Qin Kai discussed the danger of the mission and Yang Jian’s effect on its difficulty.

• Yang Jian and Li Yang recognized that the mission’s bus route began in Dachang City and suspected it involved the supernatural bus.
• Yang Jian warned Old Eagle and the other couriers not to cause trouble in Dachang City, then left with Wang Shan’s corpse and told Yang Xiaohua to bring her red balloon next time.
• Da Qiang questioned Yang Xiaohua about Yang Jian, and she explained that he had entered the Post Office to deal with the dangers its couriers caused outside.
• After Yang Xiaohua left, Da Qiang admitted he had considered stealing her red balloon, while Qin Kai warned that provoking Yang Jian would be dangerous.
• Da Qiang and Qin Kai discussed surviving the red-letter mission and reaching the fifth floor, and Old Eagle then left the Post Office.

Yang Jian left the Ghost Post Office after promising Sun Rui he would return in ten days and connect the clues linking several supernatural incidents. He restored his body, prepared for the upcoming letter-delivery mission, and went to warn Li Yang about the supernatural bus.

• Yang Jian told Sun Rui that he would return in ten days, reach the fifth floor, and end his involvement with the Ghost Post Office.
• Yang Jian returned to Dachang City and concluded that the next letter-delivery mission, the Ghost Cabinet, the Ghost Painting, and the supernatural bus all pointed toward the same old residence.
• Yang Jian sealed Wang Shan's ghost-invaded corpse in a Gold Box and used Huang Ziya's Liar Ghost necklace to temporarily restore his body.
• Yang Jian decided to bring the doll and red ghost candles on the delivery mission, but not the ghost child, and set out to warn Li Yang about the supernatural bus.
• Chen Shumei invited Yang Jian to lunch, then gave Xiong Wenwen a broom and told him to sweep the yard.

Yang Jian and Li Yang discussed the dangers and possible loopholes in the Ghost Post Office delivery mission, then Yang Jian visited Xiong Wenwen and Chen Shumei. He left after a teasing argument with Xiong Wenwen, while Chen Shumei remained embarrassed by their matchmaking jokes.

• Li Yang pointed out that the bus delivery requirement seemed impossible unless the bus stopped early, and Yang Jian explained that a ghost stopping the bus or an engine failure might let the couriers get off in time.
• Yang Jian told Li Yang to rest and said they could escape through the ghost door and abandon the letter if the mission became too dangerous.
• Yang Jian visited Xiong Wenwen and Chen Shumei for a promised meal, and Xiong Wenwen claimed Yang Jian wanted to marry his mother.
• Chen Shumei asked whether Yang Jian could give Xiong Wenwen a normal child's body, but Yang Jian said it would be very difficult.
• Xiong Wenwen urged Yang Jian to leave his girlfriend and marry Chen Shumei, and Yang Jian eventually slipped away from their argument.

Yang Jian mobilized Dachang City to prepare for the supernatural bus’s arrival and ordered the fourth-floor post office messengers detained. The city’s forces captured several messengers, while the lockdown around Chang'an Road Station remained in preparation for the bus.

• Yang Jian ordered buses suspended, Chang'an Road Station sealed, and Liu Qingqing, Yang Xiaohua, Old Eagle, Wang Feng, Qin Kai, and Da Qiang taken into custody if they appeared in Dachang City.
• Yang Jian accepted Headquarters’ assignment concerning the supernatural bus and directed Feng Quan and Tong Qian to help prepare for its arrival.
• Old Eagle was stopped at a city checkpoint and escorted away after armed personnel confiscated his luggage.
• Feng Quan confronted Qin Kai at the airport, and Qin Kai agreed to cooperate rather than resist.
• Tong Qian intercepted Liu Qingqing at the high-speed rail station, and she agreed to go with the staff.
• Dachang City’s forces continued bringing in any fourth-floor post office messengers who arrived over the following days.

Yang Jian secured the fourth-floor messengers and brought Yang Xiaohua and her red balloon to Shangtong Building while preparing for the letter delivery mission. After learning that Da Qiang had evaded the search, Yang Jian used his Ghost Domain to find him and force him to cooperate.

• Yang Jian ordered Yang Xiaohua brought to Shangtong Building and kept under guard with the red balloon, which could not be secured to anything else.
• Yang Jian told Yang Xiaohua that all the fourth-floor messengers had been brought under control except Da Qiang.
• Liu Xiaoyu reported that Da Qiang had entered Dachang City and disappeared after being spotted on street cameras.
• Yang Jian opened his Ghost Domain and confronted Da Qiang beneath a bridge, threatening to kill him if he refused to cooperate.
• Da Qiang agreed to cooperate and allowed Dachang City's people to take him away.

Yang Jian gathered the messengers in Dachang City and prepared them to board the post office’s bus for their delivery mission. The paranormal bus appeared as the deadline approached, and the group braced for whatever might get off it.

• Yang Jian had Li Yang summon the seven fourth-floor messengers he had kept confined, and he threatened them when Liu Qingqing challenged his decision.
• Wang Feng and Old Eagle urged the messengers to set aside their grievances and focus on the delivery mission.
• Yang Jian explained that everyone had to board the bus and seize a seat, warning that some passengers might be ghosts.
• Feng Quan alerted Yang Jian that a bus had appeared and was approaching along Chang'an Road.
• Yang Jian used his Ghost Eye to see the bus's rusted, damaged form beneath its ordinary appearance, while Feng Quan, Tong Qian, Huang Ziya, and the others moved closer.
