Xuanyuan Single Soldier Mecha

In 2140, a secret department in China developed a prototype of a single-soldier mecha. In 2160, China's first official prototype individual mecha was handed over to "Xuanyuan" Just when the official prototype was being exercised for the first time, an uninvited guest quietly arrived. Originally, it was just a test of individual mechas to collect data. As a result, in the first exercise, we encountered individual mechas from other countries. What kind of sparks will be created when the individual mechas of the two countries collide? What will be the result of the collision between individual mechas and biological weapons?
