Omae wo Onii-chan ni Shite Yarouka!? - Volume 2, 1st of May, Wednesday

Reincarnated into a land of cultivation, Yuan Zhou uses his Earth knowledge and assumptions to become a genius under the heavens for both business and cultivation. However, he walks the path of defiance, exceeding all rational cultivation bounds. His business ideas struggle against the stagnant culture that pervades the land, but the things he doesn't lack are his drive for immortality and power.

When an S-class elite assassin-raised captain of a special ops suicide squad comes home from a high-stakes Africa mission, he finds himself offered something that could potentially set him up for life- a curious assignment that he could use to finally exit his days of war and slaughter.

Then placed into a high-school setting, Lin Yi is tasked by the chairman of a top-tier multi-billion company with bodyguard duty for non-other than his own daughter, a certain little Miss of said high-school.

His enemies, once ranging from drug lords, mafia bosses, political figures, and national leaders, are soon replaced with spoiled kids who happen to have rich papas and mamas, and Lin Yi finds his intense expertise and high-threat skillset misused, and very underwhelmed…

But he does get a harem cast as diverse as his old enemies, so Lin Yi decides that, for the sake of messing around with girls as an invincible entity in a down-leveled environment, leaving his bloody and death-filled war days behind is something he’d definitely want to strive for.

In high school, Ling Chen was the most taciturn student in the class, always walking alone with lowered eyebrows and eyes.

The longest sentence Zhu Wenshu ever said to him was just a polite sentence at graduation, “I wish you a bright future, and I will keep in touch in the future.”

Later, Ling Chen really did have a bright future.

He was dubbed a monster rookie when he debuted, sweeping the major music charts, winning various music awards, and was followed by flowers and applause.

It was rumored that Ling Chen’s “Classmate Xiaocan” was written to his first love who had been engraved in his heart.

Friends knew that Zhu Wenshu and Ling Chen were classmates in high school, so they came to gossip: Do you know who his first love was?

Zhu Wenshan shook her head: I don’t know. It might not be from our school.

One day, the class that had been silent for a long time suddenly became active, discussing the hacking of the famous star classmate Ling Chen.

An old classmate privately approached Zhu Wenshu to complain: Thanks to the account hacker, I just found out that my remark in Ling Chen’s Q|Q was “the sixth in the fifth row.” What about you?

Zhu Wenshu laughed out loud, and couldn’t help opening Q|Q, which hadn’t been touched for a long time, and sure enough, she also received the same message.
