Chen Welding accidentally traveled through the 1937 arsenal while welding the core components of the national secret project, and was bound to the "Civilized Anchor System."
Looking at the "Made in Hanyang" that repeatedly exploded in his hand and the numb and desperate workers around him, he silently picked up the welding gun.
When the first improved barrel was successfully fired, the system prompt sounded in my mind: "The technology tree 'Basic Metallurgy' has been unlocked."
He didn't know that what he was about to weld was the backbone of the entire nation.
