Rebirth of the Great Sui Dynasty

The useless cultivator of the 21st century was beaten to ashes because of a strange catastrophe, but who knew that he was reborn in the body of a young man named Xu Shiji in the Sui Dynasty. He thought that the spiritual energy in ancient times would be more abundant, but he discovered that there was no spiritual energy at all here, and it was a pure martial arts world. After struggling, I finally figured out that the painful hard work in the previous life was ultimately wiped out. Immortality is just an illusion after all. In this life, I have to dominate the world to live up to this ordinary life. No spirit? Not a problem! There is also a body-refining technique in my memory that can be practiced without spiritual energy! When the body training is successful, I would like to ask the masters in the world, no matter how high their martial arts skills are, can they withstand the next punch?
