In mixed martial arts, I am the strongest creature in the sea, land and air

Gu Yu traveled to the world of mixed martial arts and was given by the system all the strength of Kaido, the "strongest creature in the sea, land and air" in the pirate world.

He also told Gu Yu that as long as someone in the mixed martial arts world can kill him with all his strength.

Not only can he return to Earth, but he can also gain the full strength of Emperor Huangtian.

In order to return to the earth and obtain the full strength of the Huangtian Emperor, Gu Yu began to make waves in the world of comprehensive martial arts.

"Huang Yaoshi, with your little strength, you still want to snatch Feng Heng and Huang Rong back from me?"

"Doesn't it seem that the peerless sword that Sword Worship Villa forged to deal with me is no good? It can't even break my skin."

"Sword Immortal? This sword of yours can only scratch my itch, so I will take Li Hanyi away."

"I will take your little clay figurine away. Whenever you can defeat me, you can take your little clay figurine back."

"An army of three hundred thousand wants to kill me. What a joke. No matter how many ants there are, they can't kill the dragon!"
