In the 21st century, a female military doctor, Lu Jiao, transmigrated into a novel and became the vicious mother of four little villains and the wife of the future First Assistant.

In the novel, the four little ones would grow up into villains who committed all kinds of crimes and killed people without batting an eye. Eventually, they would end up getting killed by the male and female protagonists. To avenge his sons, the First Assistant would transform into the final boss and die after committing many sins.

Lu Jiao looked at the four little ones who were only up to her knees, then looked at the bedridden First Assistant. Forget it, she would do a good deed by educating these children properly and giving the First Assistant medical treatment while she was there.

What she didn’t expect was that the four little villains and the future First Assistant would want nothing more than to send her to her death.

They attempted to strangle her in the middle of the night, use broken pieces of porcelain to slice her arteries, and poison her food. Lu Jiao was furious. “I’m not doing this anymore. If you want to become villains, go ahead.”

However, the four little ones now refused to let her go.

“Mummy, please don’t go. We’ll be obedient from now on.”

Once through the pirates, Lu En became the son of Monkey d Dragon, a grandfather named Monkey d Karp, and an unreliable and neurotic younger brother named Luffy.

Fortunately, the ghost back system is activated!

The completion of the ghost back is 10%, and the training effect is increased by 100 times!

…

One day, Lu En, a ghost-backed master, appeared in front of Luffy who was shouting to go to sea, and made Luffy cry on the spot.

Luffy: “The pirates in the sea are all monsters like my brother? I don’t want to go out to sea!”

Garp: “For a long time, the two boys, Long and Luffy, with small arms and calves, I really doubt that they are not my sons and grandsons. Like Lu En, they are the grandsons of the old man!”

Warring States: “The strongest creature in the sea, land and air is Kaido? No, it’s Lu En!”

Jiang Chen had unexpectedly found himself thrust into a world of cultivation, stepping into the role of a core disciple within a famed sect. Fated to be the villain, his future loomed with calamity. He had plotted against the protagonist, crippling his dantian and leaving him a disgraced outcast teetering on the edge of expulsion. Were it not for an unexpected twist, Jiang Chen’s part might have ended as a mere footnote in the protagonist’s glorious tale. Fully aware of his precarious position, Jiang Chen’s lips curled into a sly grin. Alone, he mused: ’Is the protagonist powerful? Without a doubt.’ ’But will I tremble in fear? Absolutely not.’ ’Why? Because I have the Immortal Great Villain System!’ ’Wait... there’s more than one protagonist?’ ’Well, isn’t that just perfect?’ With a determined glint in his eyes, Jiang Chen declared to himself, ’As the ultimate Great Villain, I will defy the will of Heaven and seize my place at the summit!’
