Reading Guide: "Don't fawn over Tang San. Everything is for your own plans. The protagonist won't make major changes to the original plot, just reap the benefits and have a good time. He won't kill Tang San, but he'll make him wish he were dead."
Transmigrate to the Martial Soul Continent from the start, and be born inside the womb? Isn't this a guaranteed death sentence?

Tang Ren: "?"
"What do you mean, great villain? This gentleman is a model young man of the 21st century, well-versed in Confucian thought."
"Ding! The Host has been awarded a beginner's gift pack."
"Ding! Congratulations, Host. You have obtained the Mangekyo Sharingan, awakened at the age of six."
Tang Ren: "Wait, did I say I wanted it?"

"I'll keep you trapped in nightmares for the rest of your life. After all, if you die, who will I fleece?"
