Su Deben, the Mystery of the Wasteland!

Every technological advancement of humankind was accompanied by a rapid leap forward in their rate of productivity.

After the discovery of fire, humans could cook food, mold pottery, and smelt iron.

After humans discovered how to use steam power, they harnessed this magical energy and used it to power machines and vehicles that could carry tens of thousands of tons.

After the discovery of nuclear fission, humans could produce and extract energy more easily and efficiently, leading it to be used as an excellent source of energy.

Before Su Mo was transported over to the wasteland, it was predicted that humankind would have to be able to successfully develop a method to contain and control nuclear fusion if they wanted to completely resolve the global problem of energy shortage. Controlled nuclear fusion could be used to expand the rate of productivity and push human civilization forward.
