The Surgeon’s Studio - Chapter 2914 A series of operations as fierce as the Tiger Alliance master Xi Chen Xi Chen

In a future timeline, the earth was visited by a species known as the Slarkovs.
Having lost their home planet and in search of a new one, earth was the next habitable planet for them.

Humans and Slarkovs made a deal with each other in return for the Slarkovs living on earth.
The Slarkovs traded their technology and knowledge for a new home.
They were similar to humans except for some of them who had slight differences so fitting into the society wasn't a problem.
Over the years Slarkovs and humans began to mate with one another and reproduce offsprings.
This in turn created a new species known as the mixed-blood.
Centuries later mixedbloods could tap into their bloodline and perform unimaginable feats.

Gustav born into an age where bloodline determines everything, struggles to fit with a useless bloodline.
His bloodline only grants him the ability to change his hair color, destroying his hopes and dreams for a great future.
His fate is turned around when an unexpected situation leads to him finding a system that grants him the power to unlock and upgrade bloodlines by completing quests but he's baffled by two quests with a five-year deadline. Success will grant him unimaginable rewards...
But only one thing awaits him if he fails... Death!

Follow Gustav on his interesting journey filled with unprecedented adventures, danger and death, maybe?

It started off peculiarly; first, his domestic cat refused to let him cuddle it.

Lin Qiushi soon found that a sense of disharmony and incongruity began to pervade everything around him.

Then, one odd day, he pushed open a door, and he discovered that the hallway he was familiar with turned into a boundless corridor.

At both ends of this corridor were twelve, identical iron gates.

Thus, the story began.

Ruan Nanzhu said to Lin Qiushi, “When you gaze into the abyss, the abyss also gazes back at you.”

Upon hearing this, Lin Qiushi sank into deep contemplation. He then pulled down the zipper of his trousers and aimed at the abyss…

Ruan Nanzhu: “…Put your pants on properly!”

Super shameless, ill, pampered gong X Shameless, calm shou; a combination of double [or extreme] shamelessness.

He Yuan had accidentally caused his own death. He had no idea he was even dead until he suddenly woke up on the hard floor of an empty room.

As he tried to get his bearings right, a strange guy suddenly popped out of thin air and he was offered a job.

The job offer granted him eternal life with the alternative being reincarnation. Most would hastily choose to be reincarnated so they can start a new life but not He Yuan.

He was skeptical, why would anyone want reincarnation? Once you reincarnated 'you' cease to exist. He didn't care about what people said about starting afresh, gaining new memories and all that.

All he knew was that once a person reincarnated, they get thrown into a different environment, different family, meet new people and in short became a different person entirely.

What scared He Yuan the most was losing his own thoughts and hence, awareness of his current self and so, he chose to accept the job.

What did the job entail? He carried out tasks given to him by people who were called 'leasers.' They were called this because they leased out their bodies to 'taskers' for a period of time to help set their crooked lives straight.

What the leasers didn't know was that the taskers got into realms and helped them so they( taskers) could focus on their own main tasks which was world/realm balance.

These realms had 'special ones' who siphoned the luck out of it. Luck was the binding force of these realms so without it, the realms would begin to break apart and deteriorate into unlivable hells.

So in essence, leasers gave put their bodies and 'payment' in the form of soul energy, taskers helped out the leasers while balancing the realms and the realms become stable once more.

Pretty straightforward right? Yes.

But can someone tell He Yuan why these world was so full of hypocrites, Mary sue and Gary stu characters who thought it was excusable to do horrible things just because they were in love?

He Yuan grit his teeth. If you want to be in love, then be in love, was there any need to use others as stepping stones?!

He rolled up his sleeves and bounced forward. Just you wait as I teach you all a valuable lesson!

I don’t need any deep relationships. I have no desire for a girlfriend, and I only require one friend who holds any value to me. Ever since I threw out my youth for the sake of efficiency, there is one person who keeps entering the bedroom of Ooboshi Akiteru. She’s neither my little sister nor my friend. She’s nothing more than a bothersome, annoying Kouhai, as well as my friend’s little sister: Kohinata Iroha.

“Senpai, let’s go on a date~! Did you think I’d say that~?”

Rather than blood, it seems like energy drinks run through her veins. She keeps occupying my bed, and she tries her best to seduce me with whatever method she can play to her favor. She’s a girl who’s constantly annoying and obnoxious around me. Even though I’m busy all day long, she doesn’t care.

And in case you’re wondering why all these envious gazes are directed at me, it’s because Iroha is actually really popular. She’s an honor student at our school with top grades to boot, and she’s known for being kind and proper to anyone she meets.

…Hey now, why are you only so annoying when you’re around me?
