Möbius Strip: the Secret of the Infinite Loop

In his third year in the forensic field, Jiang Yu saw his boyfriend Tan Heyu on the autopsy table. But he was obviously lying next to her last night, so how could it happen now? The moment the scalpel cut into his neck, warm blood surged all over Jiang Yu's body. Tan Heu is not dead yet! And she hastened his death. That day, she tasted his blood. Later, she learned that he had exchanged his death for her life. Since then, Jiang Yu has embarked on the road of saving his lover and entered a strange cycle of exploration. "Miss Jiang, have you ever heard of circulation?" This was He Jiaojiao, the first person to talk to Jiang Yu about circulation. "Then... Just... Let's go together." This was Cheng Langjin, the first person to pull Jiang Yu into the loop. "Why did you lie to me, Jiang Yu?" This was Gu Xuan, a person who had been deceived by Jiang Yu several times but still protected her. "Xiao Yu, if one day I am no longer here, you must take good care of yourself." This is Tan Heyu, his lover who was killed by Jiang Yu himself. However, when Jiang Yu gradually got closer to the truth, she realized that this was not the truth, but a Mobius strip. She had been in that strange circle, staring into the abyss.
