Invincibility starts from being watched by the sword witch

One sword parted the road of life and death, and two strokes crushed the true ancestors!
In the final battle with the Fourth True Ancestor, Jin Chan escaped from his shell and returned to this world from a foreign land. The God of Blame Cain, who had changed his name and surname to Xiufeng Prison, was invited by Nangong Nayue, and suddenly returned to his high school days.
"The strongest true ancestor is the fourth true ancestor? It doesn't exist. My favorite thing to do this time in Xiufeng Prison is to push my enemies to the corner, lift their chins, and give them a wicked smile:
"Which one is the strongest, me or the Fourth Primogenitor?"
This book is also known as "The High School Life of Blame Cain", and "The protagonist of the blood-thirsty attack is actually me, Blame Cain!" "
