Mixed Martial Arts: the Undefeated Counterattack of the East

I traveled through time and became the Invincible of the East, with a world-famous appearance and amazing talent - fortunately, the key parts are still there. But something is wrong with the world. Yihua Palace, Hulong Villa, and the Beggar Clan are all rising up together. This is a mixed martial arts hell where every step of the way is murderous!

If I don't practice the Sunflower Manual, I will definitely die; but if I practice it, I can finally keep my manhood...

In this desperate situation, I suddenly looked at the embroidery needle in my hand—— Maybe, you don't have to be in the palace to be invincible in the world?
