Longyuan Tiangongji

In his previous life, he was the top weapons engineer of the Lingtian Group, and he knew the stress of metals, the critical points of heat treatment, and the ratio of alloys - these are just "techniques" in modern society, but in Longyuan Continent, these are magical skills. While others were still using brute force to temper mortal iron, Qin Hu could already use engineering thinking to deconstruct dragon patterns and use material science to reconstruct spiritual weapons. This was his real trump card for the counterattack.
