Jiang Chenluo's sister died and was killed by the experimental subjects. From then on, he was full of hostility towards any experimental subjects. Even though the captain Zhao Yige told him that "the experimental subjects are not necessarily bad", the fear and anger in his heart towards the experimental subjects, as well as Jiang Liqing's death, still made him choose to go on this road.
Not long after Jiang Liqing died, he accepted the task of IOI in order to bury his sister. It was that day that he met the person who moved his heart, the person he wanted to protect for the rest of his life.
Intention: Don't close yourself off, love boldly
