It has been changed to the previous life, so I know it is Long Aotian
Two male protagonists + two strong men + slicing + cutting love threads and cultivating ruthless ways, leaving them to rot after death, vs. Slicing, white cutting, black and dark bt attack
Please read the introduction to the end: The year of mine clearance (but I don't know if being dead for more than a hundred years counts. There may be imprisonment.
Jiang Jianyi is the Long Aotian of this world. Qi Lianyan knows that he is a stepping stone and cannon fodder. He died after doing what he should do. Later he was reborn, but why did Jiang Jianyi hug him after rebirth and say that he smells good and likes it? Why take his clothes to wash? On the red piece of paper Jiang Jianyi asked him to sign, what was written on it about eternal life and the agreement of the same heart? Did he accidentally sell himself out?
When Jiang Jianyi met this senior brother who welcomed him with a smile, he immediately thought of using him to achieve his own goals. Everyone was his tool. At most, he would protect him. Why did this senior brother die after being in seclusion for a few years? Forget it, he was just a tool anyway.
Qi Lianyan originally wanted to leave Jiang Jianyi when he was reborn, but later on, he was tricked into helping Jiang Jianyi meet his eldest wife.
But good brother, why is the eldest wife a man, and she looks so much like you? She should be a couple.
But good junior brother, why does that Demon Lord look so much like you? Aren't you a big boss in the sect?
But good junior brother, why do the elders of the demon clan look so similar to you? Aren't you a big boss in the sect?
But good junior brother, why do the ghosts... Well, good junior brother return to the sect?
After his rebirth, he no longer wanted to fight for his obsession with his mother. He just wanted to live every day peacefully.
