I! a Master from This World! Come and Meet Me Soon!

Zhang Chengfeng obtains the "Extraordinary Expert" system. When others think he is an "extraordinary expert", he can gain expert points.

In the world of martial arts, he comes with a sword and rides the wind, shocking all the martial arts masters. In the world invaded by aliens, they shredded mechas with their own hands and shouldered the Star Destroyer Cannon, shocking the world.
