Acid rain leaves deep corrosive marks on the skin, like metal being eroded. The skin's surface tissues begin to swell, and cells die rapidly due to the acidic attack, forming grayish-black ulcers. Blood vessels are eroded, allowing the scalding rainwater to penetrate deep into the skin with a painful, burning sensation.

Humans exposed to acid rain gradually lose their sense of touch with the outside world, and their bones and muscles emit a faint burnt smell. Without timely and effective treatment, the damage caused by acid rain is irreversible and may even lead to death.

In this sudden acid rain, every drop of water became a deadly threat, allowing people to deeply experience the cruelty and ruthlessness of an apocalyptic environment.

Inside the fortress hall, the bitter smell of acid rain permeated the air. The groans of the wounded and the busy work of the medical staff formed the main theme of this moment.

The corrosive marks from acid rain are clearly visible on the survivors' bodies. Burns and ulcers of varying sizes and depths on their skin seem to tell a story of the struggle between life and death. Some people's arms were corroded by acid rain, their skin red and swollen, and the pungent smell of acid still lingered at the wounds. Others had painful scars on their leg muscles.

Inside the fortress's main hall, blood flowed in deep furrows, rain washing away the remaining debris. Medical personnel moved swiftly through this hellish scene, doing their utmost to treat each wounded person. They possessed only rudimentary medical tools, but they relentlessly began their rescue efforts.

Xiao Lin's arrival brought a semblance of order to the scene. He acted decisively, ordering people to put on protective gloves and remove the acid rain-corroded clothing to prevent further damage to the base. Everyone was told not to leave the base until the rain stopped, and looking at the acid rain outside, despair filled their faces.

Xia He was in the hall with Li Chunhua. Dr. Qian had gone to the medical station to treat the wounded. The hall of the fortress was filled with the pungent smell of acid rain corrosion. All of this was a cruel portrayal of the apocalypse.

Xiao Lin then ordered his men to clean up the mess in the hall and sent someone to count the number of casualties. At this time, Hai Dong reported, "Boss, Professor Wang took a team out to look for soil last night and has not returned yet. I'm afraid something has happened to them."

At this moment, Li Chunhua heard Professor Wang say three words: "What? Say it again, is it my old man Wang Qifeng?"

Although Haidong was reluctant to tell Li Chunhua the news, he still nodded cautiously.

At this moment, Li Chunhua's face was ashen, her hands trembled incessantly, and she kept muttering, "No, no, the old man is lucky and shouldn't be that unlucky."

Then she fell straight backward, but Xia He caught her with lightning speed and asked Xiao Lin, "Where is the medical station?"

Xiao Lin took Xia He to the medical station, where they happened to run into Dr. Qian. Dr. Qian asked, "What's wrong with Grandma Li? Did she get scared by seeing so much blood?"

Xia He said, "Grandma Li fainted when she heard that Professor Wang had gone out with a group to search for soil and hadn't returned yet."

Upon hearing this, Dr. Qian exclaimed, "Oh dear, what's going on? Quickly, put her on the bed, let me take a look."

After examining her, Dr. Qian said, "The old woman is fine, she just fainted from anger. Oh dear, what are we going to do about Professor Wang? The acid rain is still falling outside, I'm afraid it's more likely to be bad than good. Sigh."
