MTL - The Return of the Black Technology of Immortal World - v3 Chapter 295 Rejuvenate

I became a ghost in the horror game [Mystery Exploration Club ~Summer Vacation Nightmare~]. Give me back my body.Translator’s summary:Han Yoo-hee is an unlucky man who fell into the world of a horror game and became the tutorial boss.Now, wanting to go back, he will guide the protagonist and her group through the game and achieve the ending, confronting many different monsters and finding more about the truth of this world.

Kai of the Sorcerer’s Tower is one of the last mages left, barely surviving in a world ruled by creatures of the dark — where the era of mages ended, and most of the lands got contaminated with dead mana. To save his world and fulfil his master’s last wish, he put himself through a forbidden ritual, risking his soul being ripped into pieces to make his way into the past. In an era with abundant mana — an era yet to enter the Golden Era of Magic. Things go wrong, of course, as they always do, and he finds himself thousands of years before the world fell to mana contamination — in the body of a young lord, Arzan. All is not well, though, as the young lord was murdered by someone right at the cusp of a beast wave threatening the territory, while larger threats loom on the horizon. There was a lot to do for Kai to regain his former strength in this time of primitive technology, but then again, he might just be able to change that.

In her previous life, she loved a prince who didn’t love her back. She was framed and her heart was torn out. After rebirth, she wanted to live unrestrainedly, but accidentally married Ling Chen, the Fourth Prince who was calculating, manipulative, and had bad reputation.

Conspiracy, hypocrisy, greed, framing, blackmail, she took them all one by one. Getting a big payoff for a small effort, love is like a sharp knife!

Lan Ling: Why did Wangye climb over the wall and come to my room?
Ling Chen: Why do you think I’m here?
Lan Ling: Does Wangye likes climbing to someone else’s bed in the middle of the night?
Ling Chen: Presumptuous! How is this someone else’s bed?

- Description from Novelupdates

Project BIOHUMAN was supposed to be a quiet project that tested to see if they could create superhuman beings. The Creator, Dr. Vang Chang created the Numbers, ten individuals who took the BIOHUMAN serum and came out different.

Countries caught wind of this and demanded the Creator to disperse the serum to strengthen the humans. The BIOHUMAN serum was shot into the sky and dispersed all over the world. Little did anyone know, it changed Earth and everything living on it. Plants, animals and humans were genetically changed forever.

25 years later, the Creator's son, Lee Seng Chang is a high school student without any Biohuman powers. The serum had given him almost no Dark Matter and only increased his overall human abilities to a super-Biohuman level. Even with that, the power standing only made him seen as the weakest amongst everyone.

Picked on because of his powerless status, Lee Seng was left by all of his friends and labeled powerless. He desperately tries to keep going with a smile on his face. Lee Seng one day gets an option from a man with a Fox mask.

“Awaken your power but at a huge price.”

Lee Seng takes the deal and watches as the world he knew quickly changes and isn't what it seems. Put under the pressures of his Father's status and his new profound power and changes, Lee Seng battles the demons within him and the unknown coming for him.
