Naruto System in One Piece - Chapter 451: Tsukuyomi!

Grandpa Yu often repeated beside the ear of Yu Zhen, saying that he(YZ) has a soul in his body. If he doesn’t properly train in asceticism, and raise then send away the powerful soul, in this lifetime he would have to live as a bachelor. In his next lifetime he would be reborn as a lifestock animal.

Yu Zhen played on his mobile and nodded. On the surface he replied, “Uh-huh”. In his heart he laughed, “hahaha”. Keeping his grandfather in the dark was amusing so the lie was repeated for over ten years without Yu Zhen getting tired of it.

After some years, Grandpa Yu passed away and a cold-faced handsome guy came to his door in a luxury car – with a household register in his hands.

…..

Yu Zhen: The soul in my body reincarnated into someone else’s body to demand repayment, what should I do!

This is a world where humans, demons and mysterious beasts coexist. Humans cultivate mysterious qi. Demons cultivate corporeal bodies. Mysterious beasts cultivate soul perception. A legend says that in the middle of an endless rainforest, there are extremely powerful existences; they are called demon kings. Some demon kings have a tyrannical corporeal body, some are experts in illusions. Some demon kings are proficient in magic, some can even move mountains. Some demon kings are able to sense things thousands of miles away. These demon kings rarely appear in the human world. Even if they emerge in the human world, they would reincarnate in human form; assimilating with mankind while seeking to breakthrough realms…….

The little princess of the Huo family, one of the wealthiest families, was mistakenly switched out nineteen years ago! The fake heiress is well-educated, talented, and doted on, while the real heiress is an uncontrollable girl who loves to fight, has a strange personality, and had dropped out of school very early…

Transmigrating into a novel one morning, Wen Jing arrived at the side of the one he worshiped and admired the most, becoming a loyal hound that was willing to go through fire and water for his senior brother.

Even the most arrogant cultivator said: “There is no one in this world who can enter my eyes, but only Jun YanZhi is truly noble.”

Wen Jing grew up alongside his senior brother, idolizing his senior brother beyond all means.

Unfortunately, he was ignorant, and as for this novel, he had only read half of it.

Midway through the storyline, he finally realized that things didn’t seem to be the way he thought they were.

Wen Jing: “Last night, Senior brother infiltrated Master’s abode. Master, please take heed.”

His master: “Nonsense! Your master was inside the abode all night last night, and did not see anyone else.”

Wen Jing: “Last night, Senior brother left on his own without permission to meet someone. Martial Uncle, please thoroughly investigate.”

His martial uncle: “Nonsense! Last night your senior brother and I were drinking and chatting merrily, all the way until morning.”

Wen Jing: “Last night, Senior brother was improper towards me……”

His senior sister: “Nonsense! How can your senior brother possibly do that kind of thing? Don’t tell me you’ve long held those kind of intentions towards him, and unable to obtain what you wanted, you’re now framing him?”

Many years later.

Wen Jing: “There’s this evil brute, specializing in using his top-notch, exquisite looks and elegant disposition to fool people, and everyone is in the midst of danger while not even aware of it themselves.”

Jun YanZhi: “If it wasn’t for you, that evil brute would most likely still be struggling in pain and suffering.”
