Weapon

In order to strengthen the cultivators under him, the first thing that Fang Xingjian thought of was the strengthening of technology.

After all, it would take time to cultivate any martial technique or skill. Fang Xingjian didn't have so much time to nurture the subordinates he had in this world.

On the other hand, they would be able to just use technology-based weapons after he created them.

Take for example the Divine Emperor whom he had defeated in another parallel world. The Divine Emperor possessed an army of robots that dominated over the entire Earth. He even equipped all sorts of plasma weapons, participle cannons, positron cannons, antimatter cannons, and many others. The Divine Emperor even had artificial intelligence.
