Reincarnated into Madness: Yandere Family's Unwanted Slave - Chapter 13 - : The Eventful First Bath.

After suffering from a heat stroke while working under the scorching heat of summer, Lu Zhou, a hardworking but poor university student, somehow becomes the owner of an advanced technological system. With the cheat given by the system, his university life changes overnight.

A Master’s degree? Easy.

PhD? Not a problem.

From a nobody, he quickly becomes a huge celebrity in the world of science. With the missions given by the system, he is on his way to winning a Nobel Prize.

“System, can points be exchanged for money?”

“No.”

“F**k, what use are you then!?”

“This system will make you the ultimate scholar, the kind that lords over all of humanity. What use will money be to you?”

“National Immortal Cultivation World” is an immortal cultivation game that once exploded on Blue Star.

But in the past ten years, a large number of players have retreated and abandoned the pit, and the game has been shut down.

Qin Mu is the only one left to sign in every day to get experience, do quests and dungeons, and plunder resources…

For ten years, Qin Mu has occupied the first place in all the rankings, and his level has also reached the first place in the entire server.

“What a great game, it’s a pity it’s closed.”

When Qin Mu was depressed, he found that the game world suddenly became reality!

There are swordsmen flying with their swords, and their sword qi has broken thousands of miles; there are magic cultivators who violate the law and disobey discipline, and separate one side; there are immortals who set up sects and create their own fire; Qin Mu sees himself, the immortal emperor is complete…

But he found that the most troublesome thing was that all the Dao Companions he got married in the game were all realized.

Not only that, the dungeon quests he cleared in the game, the bosses he fought, and the female NPCs he stalked all came to life. The most terrible thing is that the system also exposed his identity as an Immortal Emperor!

James, a brilliant mechanical engineer and passionate history enthusiast, loses his life in a tragic house fire—only to find himself in a mysterious world as the ruler of an island nation. Armed with his modern knowledge and unwavering ambition, James embarks on a bold mission to industrialize his kingdom and build an empire on which the sun never sets.

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.
