Wei Huo entered the mechanical tower of Mechanical City. The mechanical tower was the only palace device that provided electricity to the city. It could be called an energy tower.
There would often be maintenance robots coming to repair the energy tower to ensure that the palace device could operate smoothly.
Wei Huo opened a hole at the bottom of the energy source and sneaked in. He traded for a very advanced computer and used his rich electromagnetic knowledge to build a functional mechanical core to ensure that the mechanical core could obtain sufficient electricity.
Wei Huo placed the blueprint on the table and added all sorts of materials and parts to it. A few seconds later, a small mechanical core appeared in front of Wei Huo and the golden armor.
The golden armor was confused. "What kind of mysterious scientific method is this?"
