My Sister Said Super Recovery Is the Strongest Skill

In order to resurrect his sister who died under gunfire, Huan Yuan embarked on a road full of blood and betrayal. In the first year, Huan Yuan listened to the slander of a strange doctor and was trafficked to the empire's human research institution. He was treated as a monster and dissected repeatedly in the laboratory for four years before finally escaping. In the fifth year, Huan Yuan was forcibly recruited by the empire. Together with 1,000 people, with explosive shackles on his neck, he was used as a dead soldier to raid the enemy Khan's base camp. In this battle, 999 lives were lost, and only Huan Yuan survived. In the twelfth year, Imperial researchers successfully cloned Huan Yuan's sister's body in a culture tank, but the experiment ultimately failed. The then-powerful Imperial Holy See imprisoned Huan Yuan on charges of blasphemy. Huan Yuan was tortured day and night by having his bones torn apart and his flesh eaten away. In the seventeenth year, Huan Yuan in the dungeon complied with the whispers of the demons in his ears, used his own life as a sacrifice, summoned the dead ninth-generation demon king Northrend, the Scarlet King, in the palace where people were singing and dancing, and bloodbathed the courtiers. In the eighteenth year, Huan Yuan wandered aimlessly in this world. ... In the hundredth year, Huan Yuan found his sister. Over the past hundred years, this cruel and miserable world has not changed at all. The only thing that is different is the return of my sister. The young and clean creature comforted Huan Yuan's broken heart. "Brother, didn't you agree to take me to see this new world?" "You? Haven't forgotten?" "Let's go~ Don't regret it~"
