Building 7 angrily flew to chase, but was lured by the Red Monsters into an area full of puddles. Once it landed, its foundation began to crack and fragment.
Later, A Jin learned that the island had been used as a dumping ground for hazardous waste.
The puddles were filled with strong acidic liquids, similar to the mud used by the Red Monsters, which quickly destroyed and dissolved concrete, causing significant damage to Building 7 on a mechanical level.
Building 7 was unable to remedy and self-repair. Because the entire island had been thoroughly contaminated, the more sand and mud it absorbed, the more it would be corroded by the strong acid.
At that time, A Jin smelled the pungent odor, which made him dizzy and nauseous, feeling very ominous.
He kept slapping the walls saying, "Forget it, forget it. Let's retreat, it's not safe here. Don't be contentious while outside."
However, Building 7 could not understand and continued to fiercely fight with the group of monkeys.
