The Starting Machine Is the King of War, and the Energy Amethyst Is Sold as Iron?

Once you travel through the world of robot beasts, you will be bound to the robot war king system. Su Yu thought this was outrageous enough, but he didn't expect that the initial reward given by the system was the structural blueprint of Optimus Prime? As an avid fan of Transformers, Su Yu realized that once Optimus Prime was born, it would be a dimension-reducing blow to the beast clan. In order to build Optimus Prime as soon as possible and collect all the city tokens to return to the real world as soon as possible, Su Yu transformed into a nameless and mysterious businessman, traveling around the world of robots, just to collect the raw materials to build Optimus Prime. For this goal, Su Yu actually used the energy amethyst, which was the key to the battle, to sell it for iron? The warriors of the two tribes were instantly ecstatic when they heard the news, and they all stockpiled huge amounts of minerals, just so that one day they could meet Su Yu, a great grievance! But who would have thought that after a while, dark clouds would be accompanied by lightning, flames would be accompanied by sharp blades coming out of their sheaths, and the mecha's edge would shine new!
