Ke Xue: My Guardian System Tied up Haiyuan Ai to Death

[Ke Xue World] + [Haihara Ai] + [Follow-up...] Traveling back in time as a biology teacher at Chengdidan High School, Lin Shen was bound by the system as soon as he adapted to his identity. He was given the task of protecting Haiyuan Ai. Failure to do so would deprive him of his body functions! The murder case in Mihua Library, the organizational ambush on the bus, the mystery of time and space on the night of the full moon... As a graduate student in criminal investigation, he relied on his professional knowledge and system prompts to repeatedly bring Hui Yuan Ai back from the edge of death. The pursuit of the black organization, the undercurrent of the FBI and MI6, Elena Miyano's space-time closed loop plan, the truth about the mysterious experimental subjects, the dangers of this world far exceed the comic plot. And his fake identity of "Fukada Lin" hides secrets that span time and space. "Are you protecting me because of your mission?" Hui Yuan Ai's temptation concealed caution. Lin Shen's eyes were firm: "In the beginning it was a task, and later it was a choice." The battle for the redemption of time and space in the Kexue world has begun.
