- Description from novelbuddy

Xu Xiuwen, who was battered and bruised, was reborn and found himself back at the farewell dinner after the college entrance examination. It was the year 2005. Facing the aggressive former love rival and the childhood sweetheart he once had a crush on, he decided to start a new life. After being reborn, he not only wants to recover the white moonlight that he missed in his previous life, but also builds his own business empire. Fame and fortune, career and love, he wants them all!

Earth has once again descended into chaos with the rise of the Exiles—mysterious and powerful monsters intent on dominating humanity. In response, the defenders—the army—deploy modern weapons and the dwindling resources at their disposal, but soon find these measures ineffective as the Exiles begin to evolve.In this desperate situation, a group of innovative scientists develops a groundbreaking serum that grants extraordinary abilities to those who take it, resulting in the emergence of Beholders—meta-humans, ability bearers, and superhumans. It is about time for humanity to evolve alongside its adversaries.Sky, like his colleagues, receives the serum. However, instead of the expected powers, he acquires something far more stronger —a trait linked to disaster. Additionally, he must deal with its numerous side effects, which are rather extraordinary.

When Zhou Shu woke up, he learned that he had become a Forging Apprentice at a workshop in the Forging Division of the Great Xia empire.
