The Tribulation of Immortality: Tsing Yi Tower

His name is Si Heng, and he is the last creation of human civilization in the previous era. Twelve thousand years ago, a nuclear war destroyed the earth, and researchers on the space station created him in desperate circumstances - a self-aware, immortal android. They stored all human knowledge in his body, hoping that he could live on behalf of human beings. Then, they were killed by the mutant monster they created, and Si Heng slept in the cryo chamber for thousands of years. Twelve thousand years later, the earth has entered a new era. Human beings relied on the remaining radiation to practice martial arts, and three dynasties stood firm. Si Heng fell from the space station into the Kunlun Mountains. His memory was confused. He didn't know where he came from or where he was going. He helped the young emperor of the Great Yan Dynasty unify the world, but was hunted down by the emperor because of the secret of "immortality". He established the Qingyi Tower to secretly protect the weak and desperate. He met Yun Mengyou, a woman who had been following him since she was twelve years old and waiting for him all her life. And the monster that woke up with him was slowly coming from the depths of Kunlun Mountain. This is a story about loneliness, protection and love. A person learns to become a "person" after twelve thousand years.
