He is Lu Sheng-7, the strongest ecological warrior in the Deep Tower Base, and the "clone" of Dr. Lu Sheng. This is the identity he was given upon awakening.
However, the strange memories flashed back in mission after mission, the strange resonance of the deadly ecology in the body, and the warning from the past - "Cain has awakened, don't trust the lighthouse", are all tearing apart the inherent cognition.
When he found the blueprint for his creation as an "inhuman species" in the songs of the Forbidden Land, he discovered that the existence of the entire base was a huge lie weaved to imprison and control him.
Who I am? What was the purpose of my creation? And where is the "ark" that carries real hope?
Now, he must embark on a dangerous journey to find himself and the truth, and his creator may be his ultimate enemy.
