One Piece: King of the World - Chapter 25 - : Demon Blade, Shindō!

Xu Yangyi, an 18-year-old high school student, for the reason that his older twin sister eloped with her girlfriend on the wedding day, was forced to be the surrogate bride by his own father. As a result, he became the wife of the man who should have been his brother-in-law.“You’ve gotta look at me carefully. I’m a man.” Xu Yangyi glared at He Jingyan, who was still getting fresh with him though he already knew Xu Yangyi was indeed a man.“Man?” He Jingyan fiddled with Xu Yangyi’s face with his big hand and gave him a sly smile, “You look identical with your sister, so it doesn’t matter!”

10 years ago, after “the Gate” that connected the real world with the monster world opened, some of the ordinary, everyday people received the power to hunt monsters within the Gate. They are known as “Hunters”. However, not all Hunters are powerful. My name is Sung Jin-Woo, an E-rank Hunter. I’m someone who has to risk his life in the lowliest of dungeons, the “World’s Weakest”. Having no skills whatsoever to display, I barely earned the required money by fighting in low-leveled dungeons… at least until I found a hidden dungeon with the hardest difficulty within the D-rank dungeons! In the end, as I was accepting death, I suddenly received a strange power, a quest log that only I could see, a secret to leveling up that only I know about! If I trained in accordance with my quests and hunted monsters, my level would rise. Changing from the weakest Hunter to the strongest S-rank Hunter!

Li Chengfeng, a scientific research genius of the 21st century, traveled through the Tang Dynasty and turned into Li Shimin’s six-year-old son?

  In the god-given god-level bear boy system, Li Chengfeng grabbed Li Shimin’s beard and started mad at Fang Xuanling and Du Ruhui, but there was nothing they could do about it.

  Li Chengfeng used his genius scientific knowledge to solve natural disasters by diverting water from the south to the north, and the hybrid rice developed by him can produce 2,000 catties per mu.

After destroying the Turks and subduing Goguryeo, Li Chengfeng was conferred the title of God King of the Tang Dynasty at the age of six.

It can be said that Mo Chou has no confidant in the future, who in the world does not know the king?
