《Southern archives》In Episode 8, Zhang Haiyan can no longer hide on the Bao En.He was worried that He Jianxi would be bullied if he stayed on the ship, and he was also worried that something might happen to Zhang Haixia on the Nan'an, so he took He Jianxi on the lifeboat and ventured back to the Nan'an.After returning to the ship, Zhang Haiyan temporarily resettled He Jianxi and sneaked into the infirmary alone to look for the ship's doctor.But what he saw was not the ship's doctor, but the medical staff who had been killed.This result made him realize that the clues of the ship's doctor had been cleared in advance. The next moment, the mechanism was triggered, the door was sealed, and the poisonous gas filled the air.

The killer appeared while he was poisoned and wanted to trap him in the infirmary.Fortunately, He Jianxi arrived with the ship's police, and Zhang Haiyan escaped and killed a killer in the melee.But the poison gas affected his actions, and the other two killers escaped.Zhang Haiyan inspected the scene and found a large number of military poison gas bottles hidden in the infirmary. He concluded that the murderer's target was not just himself, but all those who were tracking Dusk Grass.He re-understood the “NP” clues left by Song Chai and realized that it pointed to Nepenthes: the Nan'an itself was a giant insect-catching plant, specially designed to lure archive agents on board and then devour them one by one.

Zhang Haiyan found out that many archives agents had been lurking on the ship, but most of them were missing now, and he was even more worried about Zhang Haixia.He suspected that Zhang Ruipu had known that the Nan'an was a trap, but still let him board the ship to die.In order to force the ship to turn around, he decided to use Miss Dong.Zhang Haiyan asked He Jianxi to carry the killer's body into the third-class cabin. He observed the passengers' reactions in the dark and finally locked in the abnormal identities of Bai Zhu and a girl.The killers immediately besieged them collectively. Zhang Haiyan and He Jianxi fell into a melee, and Zhang Haiyan's injuries worsened.Episode 8 reveals the true face of the Nan'an: it is not a simple means of transportation, but a hunting ground for agents who clear the archives.

He Jianxi's role also begins to change in this episode.He was originally just someone who was taken along by Zhang Haiyan, but because of his sense of smell, courage and accidental actions, he became a key cover for Zhang Haiyan to find the killer.Zhang Haiyan asked him to carry the corpse through the third-class cabin, not only to test the killer, but also to bet that the other party would react to the corpse of his accomplice.After Bai Zhu and the girl were locked, the killer in the darkness of Nan'an was no longer hiding, and the siege came suddenly and intensively.While Zhang Haiyan had to protect He Jianxi, he also had to judge whether Zhang Haixia was also trapped on the ship. The pressure was heavier than in previous episodes.The military poison gas bottles in the infirmary further connect the Dusk Draft and the warlord forces, indicating that the people behind the scenes not only want to kill a few agents, but also have the ability to transform the entire ship into a sophisticated trap, which also makes the desire to return to rescue people more urgent.
