《Southern archives》Episode 7 first explains Zhang Haixia’s counterattack.He was not really forced to commit suicide by hallucinations, but was forced to stay awake under the poisonous attack, realizing that the so-called inner demon in front of him was a trap created by someone using dusk grass.Zhang Haixia took advantage of the situation and set up a mechanism to ambush the killer Bai Sheng and steal clues to the behind-the-scenes plan from him.The information exposed by Bai Sheng was limited, but it was enough to show that this pursuit was not a temporary act, but an organized and targeted cleanup of the relevant personnel of the Southern Archives.The new killer quickly approached, and Zhang Haixia could only continue to run for his life.

Zhang Haiyan is also advancing his own game.In the middle of the night, he used potion to draw fake red rashes on the arms of some of the boat passengers. When these people came to Steven for medical treatment the next day, he would hide nearby and observe who was the most nervous.He judged that the people spreading dusk grass would definitely keep an eye on the changes in symptoms, but when the Nan'an was about to set sail, he still had not caught a clear target.At the critical moment, Zhang Haiyan thought that the ship's doctor had never shown up and was the most suspicious, so he was about to go and investigate. When Steven couldn't bear it anymore, he led the musketeers to catch him.The fire was so close that Zhang Haiyan could only escape by jumping into the sea and swimming to the nearby Bao En.

On the Bao En, Zhang Haiyan met He Jianxi.He Jianxi was targeted by sailor Er Erlong because he exposed his money. In order to avoid the conflict from expanding, Zhang Haiyan first handed over the money to stabilize the situation, but He Jianxi misunderstood that he was timid.After the two returned to the cabin, Zhang Haiyan was treating his wounds while planning how to return to the Nan'an, because Zhang Haixia was probably still trapped on that ship.The ship's police are approaching to search, and the Bowen is not safe.On the other side, Zhang Haixia escaped from the killer and escaped into the third class cabin.The brothers are all trying to get closer to each other, but they are repeatedly separated by pursuits, misunderstandings and time differences on the ship.

Zhang Haiyan's jump into the sea was not simply to escape, but to be forced to temporarily withdraw from the Nan'an's situation.He looked embarrassed on the Bowen, but in fact he was still thinking about how to return to the real hunting ground.The appearance of He Jianxi changed his situation: this ordinary accountant did not understand the Southern Archives nor the Twilight Draft, but because of money, he got involved with Zhang Haiyan and became an unexpected partner in the follow-up operation.Zhang Haixia, on the other hand, was more like groping alone in the poisonous fog and pursuit. He used his clear will to resist the hallucination, and obtained information from Bai Sheng, which showed that the killer camp was not monolithic.Episode 7 juxtaposes two escape spaces. One is dealing with real-life troubles on the Bao En, and the other is continuing to evade assassination in the third class cabin of the Nan'an. The closer the two want to get closer to the truth, the more they are drawn by the order, gunpoint, and murderer on the ship.Zhang Haiyan did not give up the return plan, and Zhang Haixia did not stop looking for his junior brother. This two-pronged advancement made it logical to return to the Nan'an in the next episode.
