I Became the Strongest by Burning My Blood

Blurb:

Also known as The Ascent

After a red moon appeared, abnormal creatures began lurking beneath the neon lights of the city, and corrupted monsters bared their claws and fangs at humanity.

So Dongxia established the Office of Abnormal Affairs to protect the public and maintain social stability.

After being attacked by an anomaly, the young Lu Shiyi found a roulette wheel in his mind.

Only... this golden finger is a little questionable.

Critical Damage (Damaged Version): The lower your health, the higher your critical damage.

Clutching his chest where he'd been stabbed, he casually slapped out a hit dealing eight hundred times critical damage. The abnormal creature's head burst apart, and it died with its eyes wide open. The officials who arrived to rescue him stared: Wait, did he just slap an abnormal creature to death?!

Does that even make sense?

Lu Shiyi: [Shy]

Swordsmanship: Divine (One-HP Version): The lower your health, the more divine your swordsmanship.

When he encountered an abnormal creature head-on, his comrades were killed, and the badly wounded Lu Shiyi picked up a crowbar from the ground. With one stroke, he sliced off the top of a mountain, leaving an impossibly smooth cross-section on the abnormal creature.

Team leader: Holy crap, the Crowbar God?!

You're saying you killed an abnormal creature three levels above you with nothing but a crowbar?!

Lu Shiyi: OvO

Word Spirit Art (Damaged Version): The lower your health, the stronger your word spirits.

Endurance (Damaged Version): The lower your health, the longer your stamina lasts...

No, wait, aren't there any skills that don't cost health?

The roulette wheel stuttered and stopped in a pitch-black section:

Immortal Body of Undying Destiny (Glitched Version): When health reaches 0, passively activates. Sanity: -100. Combat power: +1000.

Lu Shiyi crawled out of the morgue with an utterly speechless look. He'd gone from merely being anemic to repeatedly dropping dead and getting back up, and now he was the unhinged version.

A sickly young man joined the Office of Abnormal Affairs. He was always on the verge of death, fainting as soon as he stood up and wheezing whenever he walked. At first, nobody had any faith in him.

He's so weak. Are we just feeding him to the abnormal creatures?

But then... when he came face-to-face with an abnormal creature, the sickly young man instantly grew excited. His blade flashed from its sheath. First, he cut himself, then, amid a shower of blood, he minced the anomaly into tiny pieces.

"Hahahahaha! This is great!"

"You think you can get away with that?!"

"Show me those teeth! I'll teach you to bare your fangs!"

Everyone: ?

What was that noise?

He was the one baring his teeth!

Didn't he just stop breathing?

He... he's the most abnormal one here, isn't he?!

Swept along by fate, the young Lu Shiyi stepped into the other side of the world. At first, nobody believed in this sickly young man who coughed up blood with every step. But later, he stood with his sword in hand

My name is Lu Shiyi. I come from Dongxia. I go forth to slay the abnormal and protect all living beings.

And here's a little preview of another story: My House Connects the Yin and Yang Worlds

A crime investigation story with a touch of the supernatural

Blurb:

Zhao Yang spent 200,000 yuan on a bargain house in the city center, never imagining that ghosts really existed. His house became the underworld's office for wronged souls in the human world, where souls unable to enter the cycle of reincarnation appeared every day.

With no other choice, Zhao Yang became a part-time underworld messenger, seeking justice for the dead and calming their grievances

He helped a murdered girl find her body and gained her specialized drawing skills.

He helped an abducted child find his parents and gained the child's keen sense of smell.

He helped a murdered old man pass on a clue and gained the old man's mathematical expertise.

As he helped souls seek justice, deliver dreams, and resolve their grudges, Zhao Yang inevitably became involved in one case after another.

Police: Oh crap, it's that guy. Another murder case!

Criminals: Why is it you again? Why is it still you? Why is it always you?!

Zhao Yang: All right, next. How did you die? What do you need? Just so we're clear, I don't take jobs to kill people, and I don't take love confession jobs. I can help find your body, call the police, deliver a message, or say goodbye. I can even walk your dog... The Lieyang Detective Agency is at your service.

The newly arrived ghost: ...?

Has the underworld's office gotten this casual?

A friend's recommended novel: A Guide to Cultivating Immortality as an Invisible Person. Blurb:

Wen Cun, who had almost no presence, transmigrated to a cultivation world and became an outer sect disciple with pitifully little spiritual power.

In the cultivation world, strength was everything. The weak could only be preyed upon and had no means of fighting back.

Wen Cun was useless and constantly overlooked, so he never got any resources. Even finding enough to eat was a problem.

All he could do was keep his head down and get by on one bun a day.

Then, one day, everyone finished fighting and walked right past him as if they were blind.

Looking at the treasures scattered all around him, Wen Cun, a person who might as well have been invisible, finally understood.

Having little presence does not mean you're a useless waste.

Having little presence means a golden finger, which means picking up treasures as you please, which means easily surviving to the very end.
