From the Military Coat at the Beginning to Saving the Entire Universe

Liu Xiaoyu, an ordinary young man from Northeast China, was "luckily" selected from among eight billion people in the world and sent to a world with multiple layers of disguise to complete the designated mission from scratch. This world is dotted with time-travelers and rebirthers from real life. Because of their bizarre encounters, they randomly came to the current time and space background. After these people met Liu Xiaoyu by chance at a specific time, they used their expertise to help him complete his mission. The main mission is absurd and clueless at first, but Liu Xiaoyu can easily handle it with only the twenty-four simplified Tai Chi and radio gymnastics. Later, he was pushed and forced by various forces, and by chance, he discovered several secret crossing points in the current world. Because of this, the current time and space background and the truth behind the mission gradually surfaced. The truth is far beyond Liu Xiaoyu's imagination. Originally, he just wanted to clear the mission, but unexpectedly, the interlocking plots were related to the lives and deaths of hundreds of millions of people. Liu Xiaoyu eventually became the leader of the ancient secret organization, the Creation Kiwanis Club. In addition to competing with opponents for survival resources, they also found a way to reverse the time and space of the universe - using the hidden information in Poincaré's return to activate the dimensionality-raising and reducing-dimensionality bus system. After entering this device, you can roam freely in the universe. This is also the scientific verification of the "Three Thousand Worlds".
