…

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!”

- Description from novelbuddy

Sam Sanderson is envied by many for his job, however he himself didn't seem to like it much.

Due to his expertise in nanotechnology he was tasked with monitoring the state the Valkyries, humanity's strongest weapons who all just happen to be made into gorgeous females.

Forbidden from even touching any of them, Sam spends his days in agony watching flowers he couldn't hope to touch. However one day all of that seemed to change.

Tan Rou only learned that she wasn’t the Tan family’s daughter when she was seventeen years old. She went from being a rich young lady to living in the slums. The parents she adored belonged to someone else, and this series of knockdowns was hard for a seventeen-year-old girl to accept. She wailed like a child for the sake of proving this was all a lie. The vicious words she spouted had hurt her biological family but she didn’t notice.

She thought the Tan family was her real family despite them seeing her as an eyesore, and was even naive enough to want to befriend the Tan family’s real daughter, Tan Jing. Alas, the latter drugged her drink and arrange for a thug to rape her. Tan Jing even brought their classmates along to catch them in the act so Tan Rou was now tainted for life. After being reborn, she looked down at the man she was stepping on. Tan Rou swore not to be a useless wretch in this life or be bullied to death.

She would stomp on those who wronged her and make it up to her real family. They wouldn’t have had to die tragically on the streets in the past life had it not been for her. Tan Rou turned completely evil after crawling back out of Hell. Everyone claimed that the real young lady was educated and talented, while the fake young lady was arrogant and incompetent. Tan Rou scoffed upon hearing this. She held back her brother from trying to stand up for her. “We have all the time in the world. Let’s just wait and see.” Just as everyone was waiting for Tan Rou to make a fool of herself…

A top-class perfumer, a top scholar, a world champion… The fake young lady’s multiple identities kept getting exposed one after another, bumping her up to number one on the trending search, shocking the world. Wait, where was the promised humiliation?

After transcending to a new world, Ye Xuan miraculously obtained the Swallowing System.
