Acid rain is usually divided into three levels based on pH value:
Weak acid rain: The pH value is between 4.5 and 5.6, which is close to the lower limit of the pH value of natural precipitation, but is already a mild pollution.
Moderate acid rain: The pH value is between 4.0 and 4.5, which will have a certain impact on the ecosystem.
Strong acid rain: pH value ≤4.0, which poses serious harm to the ecology and even buildings.
The sudden acid rain seemed like a warning.
Shi Man had a hunch that this acid rain was just the beginning. She even had some unfamiliar images in her mind. At first, no one paid attention to the light rain and continued to search for supplies outside.
Until the rain fell one after another, one day, it rained heavily, and the raindrops falling on people were like magma, corroding the living people beyond recognition like wax figures.
Shi Man took a deep breath and pulled himself away from his memories.
"We contacted our hometown to prepare emergency measures to prevent acid rain, and the relevant materials were quickly put into use."
"Tell them to prepare for the worst, as acid rain is likely to develop into super-strong acid."
The pH value applies to dilute solutions, which are solvent environments close to water. But superacids... well, that's a completely different matter. Sulfuric acid, for example, falls into the category of superacids.
Song Yan immediately contacted his hometown, and Shi Man also called up the attribute panel of the combat uniform. She looked at it carefully several times and was relieved after confirming that the combat uniform produced by the mall could protect against super strong acid.
"From today on, whenever you leave the Pure Land, you must be fully armed. The combat uniforms can protect against super-strong acid, so we don't have to worry about sudden rainfall."
Everyone nodded, but Qi Hao said worriedly, "We have protective gear, but what about Niu Niu and my brother?"
“It’s a problem indeed.”
When in doubt, go to the mall.
The alienated crocodile biological skin and bone vests equipped on Milk and his brother are covering the surface of their torso skin. They are absolutely no problem in preventing puncture and extrusion, and also have a certain degree of protection against strong acid, but there is no protection for the head and limbs.
Baiwan and Xiong Er are still on air defense. Baiwan...this kid, except that his shit attracts other kids, Shi Man doesn't see anything special about him.
Xiong Er is mainly powerful in speed, but his attack power is actually average.
If you encounter a battle in the later stage, there is a high probability that Baiwan will not be of much help, but Xiong Er can be an assassin and a monster-luring bear.
Shi Man thought about it while searching in the mall, and finally she found a useful product in a corner:
[Product Name: Alienated Whale Stomach Stretchable Soft Bag]
Price: 3000
Instructions for use: It can resist strong acid and can be stretched and retracted at will, up to the size of an adult sperm whale's stomach.
Shi Man bought 5 of them directly. When she got the stretchable soft bag, it had a fishy smell. Shi Man pulled it and it opened easily. It was like a soft rubber with excellent elasticity.
She called for Milk, opened the soft bag and easily covered the kitten inside. There was a retractable drawstring on the bag. After tying the drawstring, she threw it over her shoulder, just like a real-life version of "cat in a sack".
