I Upgraded on My Own

A system prompt changed Lin Ye's ordinary fate. [Bloodline Awakening Program Start: 1%...] [Shadow ability is awakening...] [Detected Lin family bloodline: Son of the Bridge] When his sister Lin Xiaoyue was taken away by the mysterious administration, the sleeping power of blood in Lin Ye exploded. The XB-27 incident that devoured his parents seven years ago was actually the beginning of the energy imbalance between the two worlds! In order to save his sister, Lin Ye embarked on the road of shadow hunter. Every battle and every upgrade brings him one step closer to the truth. When shadow lines spread on his skin, and when his abilities continue to exceed limits, he discovers that he is no ordinary human being, but a "son of the bridge" who can connect two worlds. Passing through the Shadow Gate and going deep into the source of purple energy, Lin Ye must find his parents before his bloodline is fully awakened to prevent the energy collapse of the two worlds. The Bureau's dark plan and the "Lin Family Bloodline" experimental subjects they created are watching all this with eager eyes... When upgrading alone becomes the only way to salvation, the boy's choice will change the fate of the world.
