What kind of cultivation novels could make the main character invincible after his appearance?

I recommend the following two invincible cultivation novels to you: "Invincible in All Worlds: Enslaving the Gods" and "Undefeated Cultivation Upgrade". Among them,"The Invincible in All Worlds: Enslaving the Gods" was a fantasy-oriental fantasy novel. It was about the protagonist and the school belle who transmigrated into the fantasy world of cultivation. They were invincible as soon as they appeared, which gave Yang Cheng a headache. With just a slap, elite geniuses were sent flying, and even ancient giants had to kneel and tremble at their feet. They were omnipotent. "Undefeated Cultivation Upgrade" was a Xianxia fantasy immortal cultivation novel. The protagonist carried the Undefeated Cultivation System and was extremely cool. He killed monsters to level up and killed people to level up. I hope you like this fairy's recommendation. Muah ~😗
