Fourteen years ago, the Gunko and several God's Knights possessed by Imu did not gain any advantage. God's Knights even had their immortality broken by Loki. After that, Imu led the God's Knights away, and the demonized guards left behind were all slaughtered by Loki. This is the crime Loki committed!
Therefore, if the World Government wants to subdue the Elbaf, it must first get Loki to surrender. This prince's role is too crucial; what they need is a unified nation!
Let's go back to the present!
When Shamrock and Gunko teleported to the abandoned palace, the aura emanating from them was sensed by Mountain Eater Gaban had lived in Elbaf for over twenty years. Yes, it was Gaban, one of the iron triangle of the Roger Pirates, the left arm of the Pirate King Roger. He had lived here ever since the Roger Pirates disbanded!
Gaban was very familiar with that special aura, and he could hardly forget it, because he had sensed it once before, fourteen years ago, together with Shanks!
On that day, King Harald of Elbaf died in that palace, and Prince Loki became a patricide, despised by everyone in Elbaf. Now, sensing that aura again, Gaban could not miss it again, so he went to the abandoned palace alone to check the situation!
Meanwhile, Straw Hat Luffy, decided to release Loki from his imprisonment in the Underworld after just a few words from Loki; the key was in the abandoned palace.
Loki was subdued and locked up here by Shanks six years ago. He has the blood of Ancient Giant, is nearly 100 meters tall, and is definitely not weak!
So Luffy and Zoro, who were searching for the key, encountered Mountain Eater Gaban, who came to investigate. Gaban gave them a taste of their own medicine, showing the two rookies Luffy and Zoro, the power of the older generation!
After a brief exchange, they parted ways. Luffy had to go rescue Loki, while Gaban left the abandoned palace to continue searching for that special aura he had sensed earlier!
While Luffy was leaving the Underworld to find the key, Shamrock had already arrived at Loki's place with Gunko, so the two sides completely missed each other!
Shamrock was there to accomplish one of their tasks: to get Loki to submit to the World Government and join the Holy Knights, which was the plan for recruiting strong individuals that Vic had heard about from the Great Boar Warcury!
However, Loki remained unmoved and showed no sign of wavering, and he deeply despised his father Harald, who had sold his soul to the World Government!
Loki's words and attitude enraged Shamrock, and then the two God's Knights who came to Elbaf dealt a brutal blow to the offending Loki, piercing Loki body and leaving him barely alive!
Since Loki wouldn't back down, Shamrock decided to use the most forceful means to subdue Elbaf!
He had Gunko summon two members of the Holy Knights, one of whom was Saint Jiringomu, Paramecia Dream-Dream Devil Fruit User, and Saint Sommers, a Thorn-Thorn Devil Fruit User!
Shamrock intends to use the Devil Fruit abilities of these three members to play a game of who is more important: a Giant Race child or the Elbaf's loyalty!
The three worked together seamlessly. Jiringomu put the children at the Walrus School into a dream, guiding them to dream of enormous monsters. These monsters then materialized in the real world and began wreaking havoc on the Sun World of Elbaf!
Then, Gunko's Arrow-Arrow Fruit activated, and all the children who were dreaming were guided by arrows out of the Walrus School and headed towards the end of a branch of the Treasure Tree Adam!
Saul, the librarian of the Owl Library, discovered the unruly children and tried to wake them up, but he was pricked by invisible thorns as soon as he got close to them. The more he cared about the wounds, the deeper they became. This was the Devil Fruit power of Saint Shepherd Sommers!
The three combined their abilities to kidnap the children from the Walrus School, turning them into hostages who could not be rescued!
Saul's actions were discovered by Saint Shepherd Sommers, and he collapsed into Saint Shepherd Sommers's thorny vines. However, Robin and Chopper, who were hiding in Saul's hair, were not discovered by Saint Shepherd Sommers. The two hid in the hair, trembling with fear!
With hostages in hand, Saint Shepherd Sommers began his obedience test. He ordered the giants to burn down the library and school, or else he would make the children jump off the Sun World one by one!
This was an obedience test, designed to make it easier for the giants to submit to them later, and also to destroy the vast number of books that had survived from Ohara!
So many years have passed, Ohara Incident is no longer a secret. The World Government has long known about Saul and Robin, so those books that are helpful for studying Ancient Script must not be left behind!
Of course, there is also the intention to destroy the culture and history of Elbaf, so that if this continues generation after generation, the future Elbaf will be forever driven by the World Government, which is the most insidious point!
While Saint Shepherd Sommers was using the child as a hostage to threaten the Elbaf into burning the books, Robin endured it all, but finally couldn't hold back any longer and ran out from Saul's hair!
She seized an opportunity and used her Flower-Flower Fruit power to conjure a giant hand, shoving Saint Shepherd Sommers away with a swift and powerful blow. Saint Shepherd Sommers flew out, coughing up blood. Robin pressed her advantage, conjuring several arms on Saint Shepherd Sommers's body, some Saint Shepherd Sommers his neck, others immobilizing his lower limbs!
Saint Shepherd Sommers was indeed a little surprised at first, but he quickly recovered. He was immortal and possessed the arrogance of a god. A few arms were no threat to him at all. Besides, he was a Thorn-Thorn Devil Fruit User. How dare anyone get close to his body? That made things much easier!
Before he could even move, his body began to move uncontrollably, leaning backward. The next moment, he felt his spine snap, and his body felt as if it had been folded. This was Robin's signature move: breaking the enemy's spine!
If it were an ordinary person, a broken spine would render them unable to move, even if they didn't die. But Saint Shepherd Sommers wouldn't be like that; he was God's Knights with an immortal body!
Saint Shepherd Sommers was recovering his twisted body while counting down the time until he pushed the child into the Sun World, seemingly unconcerned about Robin's attack, leaving everyone around him dumbfounded!
Upon seeing this, Robin recalled what she had seen in Egghead. It seemed that the Five Elders were also like this; they were immortal as well!
With a sudden thought, Robin devised a plan. Before Saint Shepherd Sommers had fully recovered, she rushed forward and pounced on Saint Shepherd Sommers, as if several arms had sprouted from her body to hold Saint Shepherd Sommers tightly!
Due to inertia, the two of them flew out of the tree branch area and fell down. This was exactly what Robin planned: to kill Saint Shepherd Sommers once to remove his thorn ability, so that she could save the children surrounded by invisible thorns while Saint Shepherd Sommers was resurrecting!
Saint Shepherd Sommers certainly wouldn't just stand by and watch himself fall to his death, even if he were immortal. It was a matter of face as God's Knights. So, while falling, Saint Shepherd Sommers suddenly activated his Devil Fruit power, and many sharp spikes grew from his body, piercing through Nico Robin's body who was holding him!
Robin let out a scream as her body instantly turned into flower petals and scattered. It turned out that Robin's body was just a clone, and the mutual destruction was merely a facade!
She knew that the other party was immortal and could not possibly die, so she was even less likely to use her own life to buy herself a little more time. She also had a backup plan!
