In the earth and star world, battle armor is the most important thing! Lu Yu traveled through time, but found that his situation was not optimistic. Having awakened the Technological War Armor Master, he simply couldn't come up with the funds needed to build it, nor did he have a decent blueprint. Fortunately, the Kamen Rider BOSS system has arrived! As long as your consciousness is connected to the dungeon, you can open the hidden dungeon as a BOSS, kill the adventurers who come to challenge, and obtain the equipment and materials they drop! Lu Yu got into the soul with his first shot at the beginning, directly drew Yak 1, and obtained the 01 production blueprint. So from then on, a Kamen Rider dungeon BOSS began to be active in dungeons of all levels, harvesting the wealth of all adventurers. This instantly detonated adventurers around the world, and they all participated in the plan to conquer Lu Yu! … When the global copy was opened, Lu Yu put on the golden belt and descended powerfully in the long river of time.
