Bathing in a Sulfuric Acid Pool

At dusk, Bai Ye stood before his little house. At the entrance lay a tightly wrapped package.

He bent down and picked it up, but just as he was about to go inside, someone behind him called out.

"Hello, did you request doorstep delivery?" the courier asked Bai Ye, who was about to enter the house, while checking the address on the shipping label.

Seeing that his delivery had arrived, Bai Ye turned around and nodded. "That's right, it's mine. The last digits of my phone number are ****."

The courier froze for several seconds upon seeing Bai Ye's face. Then, somewhat embarrassed, he pulled out the receipt. "Please sign here. Also, you ordered quite a lot. Do you need me to help carry it inside?"

Bai Ye casually signed his name and shook his head. "No need. Just leave it here. I'll carry it in myself."

"Oh, okay." The courier nodded and struggled to unload the large item from his vehicle, setting it before Bai Ye. Then he watched in astonishment as the beautiful, seemingly frail young man effortlessly grabbed the several-hundred-pound package with one hand and briskly carried it into the house.

Once inside, Bai Ye eagerly opened the package. Inside was a custom glass bathtub, 160 centimeters long and 70 centimeters wide, along with a fifty-centimeter glass rod.

As for the package that had initially been left at his doorstep, it contained ten liters of 98% ultra-pure concentrated Sulfuric Acid stored in glass containers.

Buying it through legitimate channels was too troublesome, so he had purchased it from the Dark Web.

Under the light, the glassware glimmered brightly, looking exquisitely crafted.

With great anticipation, Bai Ye carried the custom glass bathtub into the bathroom. Then, after putting on protective gear, he took out several barrels of purified water he had bought from the Walmart next door and poured them directly into the tub.

He then unscrewed the glass cap of the concentrated sulfuric acid and slowly poured it along the inner wall of the glass bathtub.

As the dilution process continued, he watched the concentrated sulfuric acid mix with the purified water while gently stirring it with the glass rod, continuously releasing heat.

Watching the colorless, odorless sulfuric acid flow into the glass bathtub, Bai Ye waited until it seemed sufficient. Looking at the faintly warm pool of diluted sulfuric acid, he took off his gloves and lightly dipped a hand inside.

Feeling the slightly warm water, Bai Ye removed everything he was wearing except his hood. Then, expressionless, he slowly lay down in the tub, leaving only his head exposed as he savored the mild corrosion of the highly diluted sulfuric acid on his body.

As long as one's mind did not give up, there would always be more solutions than difficulties. Since exercise was supposedly a process of muscle destruction and repair, he might as well go all the way and give the epidermis a little intensity.

His constitution had already reached 1.3. While retaining elasticity, his epidermis had also gained considerable toughness.

Tests had shown that an ordinary knife needed some force to cut his skin, and any wound would stop bleeding within thirty seconds before scabbing over and healing within a day. These signs already marked the beginning of his transformation beyond human limits, and they were precisely what gave him the confidence to bathe in sulfuric acid.

I might as well sleep here tonight. Bai Ye calmed himself, ignored the faint stinging brought by the sulfuric acid, and began cultivating the Purple Mist Divine Skill. Before long, he entered a state where he forgot both self and surroundings.

Throughout the process, the sulfuric acid in the glass bathtub continuously eroded Bai Ye's skin.

Although the diluted sulfuric acid had become so weakly corrosive that it was almost harmless, after several hours, Bai Ye's skin gradually began to fail.

However, as his epidermis was corroded away, Bai Ye's healing ability began to take effect. Destruction and healing continued in an exquisitely delicate balance.

At seven the next morning, purple qi wreathed Bai Ye's face as he exhaled a long breath of turbid air and slowly gathered the internal force flowing throughout his body back into his Dantian.

Feeling the eight strands of true qi lying quietly dormant within his Dantian, Bai Ye slowly opened his eyes, filled with emotion.

The improvement in aptitude brought by a 1.3 constitution has doubled my cultivation efficiency. The true qi I accumulated in one night is actually equal to the total from the previous two nights. If my constitution reached 1.4 or 1.5, then wouldn't I... Hiss.

Bai Ye suddenly sucked in a light breath of cold air. Just as he tried to get up, he discovered that the skin below his neck hurt as though it were being pricked by needles.

Looking down, he saw that the skin soaked in the bathtub was blood-red, like a cooked shrimp.

He practically trembled as he climbed out of the tub. The stabbing pain from his skin, especially his lower body, made him gasp repeatedly.

This feeling, comparable to being skinned alive, was far too intense. His body was practically being marinated by sulfuric acid.

As Bai Ye stepped out of the bathtub, a new description appeared on the status panel.

You completed a diluted sulfuric acid bath lasting 9 hours, 17 minutes, and 26 seconds...

Repeat 5 times to increase the constitution cap by 0.1

Seeing the prompt displayed in the description panel, Bai Ye's eyes lit up. His attempt had indeed been correct. Destruction and regeneration of the body really could increase constitution. Next time, he would lie in the sulfuric acid pool and use electroshock therapy—cultivating both inside and out. The results would definitely be even more outstanding.

Bai Ye got up, endured the waves of pain coming from his skin, and slowly dried the droplets from his body with a towel before putting on his clothes.

He glanced at the time. There was still plenty of time before school, so Bai Ye wolfed down some food to fill his stomach, then started doing push-ups in his room.

With his strength at 1.4 and constitution at 1.3, Bai Ye's physical abilities had begun to gradually approach the limits of the human body.

He did not even need internal force for endurance. Relying purely on physical stamina, he could do more than three thousand push-ups in a single session.

Enduring the stinging pain from his skin rubbing against his clothes, Bai Ye spent an hour completing more than 5,800 push-ups with proper form before exhausting his internal force and collapsing to the floor.

During the process, sweat seeped out of his skin like salt being sprinkled onto wounds.

Too slow. Now that my stamina has improved, relying solely on bodyweight training takes far too much time. As expected, I still need weighted training. Bai Ye was somewhat dissatisfied as he looked at the time wasted.

He looked up at the clock. There were only about ten minutes left before class. Bai Ye calmly picked up his backpack, opened the door, and sprinted toward school.

The route that had been nearly hellish for him three days ago posed no challenge at all now. He did not even breathe heavily throughout the entire run.

His only discomfort was the painful friction caused by his clothes while running.

As he ran, his body almost became an afterimage. Pedestrians were overtaken before they could even react, left staring blankly at his retreating back.

You completed a run with a total distance of 2,024 meters and an average pace of 2 minutes 20 seconds/km. Repeat 15,328 times. Long-term bodily damage: 0.11%. Can recover naturally when constitution reaches 1.5.
