Me, a Deadweight? My Entire Crew Is S-Rank [Wasteland]

Humanity evolves, supernatural abilities awaken, and a wasteland era arrives overnight.

Lin Tang awakened an ability too... a useless one.

He felt like a portable power bank and a human healing spell combined. Unfortunately, his energy signature was so faint that ordinary evolvers couldn't sense it at all.

In a family that prized strength, he was little more than a pretty deadweight.

So Lin Tang, who couldn't lift or carry a thing and whose ability was next to useless, was very reasonably kicked out of the house, accompanied by a few pitying looks that said, "Good luck out there."

Lin Tang stood on the desolate street with his little shabby bag and sighed.

Fine. If this place won't have me, there's somewhere else that will.

He opened a general store in the wasteland and became a small-time shopkeeper.

It didn't take long for the wasteland's top powerhouses to discover a secret.

A comforting aura that made you crave it clung to a certain little guy wherever he went.

Only a handful of S-rank powerhouses at the very top of the world's hierarchy could faintly sense that allure.

It was the most effective way to soothe and heal their rampaging powers.

And so everything changed.

The infamous Butcher of the Rainy Night carefully offered him a bag of rare energy crystals.

"Boss, could I get ten more minutes of 'charging' today? I got hurt during yesterday's hunt..."

The unruly Lord of Flames obediently helped grill meat.

"Boss, is the heat all right? Um... could you soothe my rampaging fire core later? I've been having trouble controlling it lately."

Lin Tang: ???

I just wanted to quietly stock up on food and build a safehouse.

Why were the big shots lining up to work for him, with their only payment being head pats (healing) and a recharge (soothing)?

Later, Lin Tang's safehouse became the strongest fortress in the wasteland.

People called him the Merchant of Miracles.

One day, Lin Tang found a badly injured, bewildered, and incredibly handsome man in the ruins.

The man had lost his memory and was like a giant dog that had been abandoned.

All he did was tug at Lin Tang's sleeve and gaze up at him hopefully.

Lin Tang's heart softened. "Fine, come with me. I'll feed you."

Later, the super-powerhouse who had regained all his memories, and could make an entire faction tremble with a lift of his finger, skillfully massaged Lin Tang's shoulders, speaking with a hint of barely concealed grievance:

"Boss, that new S-rank guy was looking at you funny today!"

Lin Tang flipped through his ledger without looking up.

"Don't start. He's here to discuss business."

"Oh."

After a while, the man leaned close to his ear again.

"Then look at me more, Tangtang. I'm stronger than all of them. Everything I earn... I'll give to you."

"And I'll give you myself, too."
