I Have a Pair of Eyes That Become a Devil in the Dark

My sister has leukemia and her family is very poor and cannot afford the medical expenses. In order to raise enough medical expenses for his sister, Li Yan sold his life to the Dihao Club and decided the outcome, as well as life and death, in the death arena. When he was about to be beaten to death by his opponent, he received a strengthening potion and his eyes mutated. Li Yan called it the magic eye. Because eyes can absorb the life of others and evolve. A blood jade demonic eye that swallows metal to strengthen the body. The second blood jade demon eye can restore injuries by storing life. The three-blood jade magic eye can copy the opponent's ability and dismantle it for use. Four Blood Jade Demonic Eyes? Six Blood Jade Demon Eye? Nine Blood Jade Demonic Eye? After Li Yan appeared, hostile forces such as the Dark Parliament, the Holy See of Light, the Avengers, Tiandao Sect, and Lianxian Pavilion appeared. They will no longer fight to the death, but will unite as one to kill Li Yan. Li Yan was very distressed. Although I have a pair of devil eyes, I really don't want to kill anyone anymore. Please let me go and let me enjoy life quietly, okay? Why are you forcing me to become a demon?
