Li Tian has maintained this posture for almost an hour, and his arms are a bit stiff. Fortunately, there is no major problem. He can just move occasionally.

Tang Wan also woke up at this time and was surprised when she saw that the blisters on Tang Xin's skin in the bath were much smaller.

Why is all this happening?

"Will salt water cure her?"

Logan asked in a low voice.

"That's right. At least it can keep her out of danger."

What Li Tian used was a very common chemical method called salting out method. This method should be in the junior high school textbook. Of course he had never learned it. These were all encountered when he was following the Ghost King.

When he arrived, the Ghost King explained the principle to him in detail.

Salting out method, strictly speaking, means that only a certain amount of salt can be melted in a certain amount of water. This is called the saturation of salt. If the water in the bathtub contains a relatively large amount of salt, then after it comes into contact with the blisters on the skin,

, the water in the bathtub will slowly absorb the water in the bubble, making the saturation levels of both sides the same.

Because the water in the body is definitely not as salty as the water in the bathtub, the side of the bathtub will absorb a large amount of water from the skin, causing the saturation (saltness) on both sides to reach a balance. The skin is like a filtering device.

The process may take several hours to complete, but will not cause fatal damage to a person's skin.

If you go to the hospital, you may just open the blisters and release the water inside, but the skin will be useless and will slowly fall off.

According to Tang Xin's current situation, 80% of the skin on her whole body will fall off by then, and she probably won't be able to accept it, especially the area on her face.

With this method, at most a few broken blisters will leave a little scar. That's because that area of ​​skin is broken, and salt can get in. Salt is slightly corrosive, and its chemical component is sodium dioxide.

, sodium is a metal.

The broken skin will definitely be eroded to a certain extent and may leave light scars after recovery, but it can also be slowly recovered through acquired maintenance.

Just like inside a glass cup, the middle is cut by a piece of filter paper. If you put salt water with a very high concentration on one side and fresh water on the other side, then the water on both sides will be equally salty after a while. This is because the water on both sides and

The salt is exchanged through the filter paper, and it will stop when the salt concentration of both sides is the same.

Skin is different from filter paper. Water can easily come out of the skin, just like sweating. There will be no problem if the cells move a little.

However, it is more difficult for moisture to enter through the skin, because the pores have a natural repulsion force against external moisture. Otherwise, if you swim for a few hours, wouldn't you directly gain dozens of pounds?

It uses the huge concentration difference between the inside and outside of the skin to allow the water in the bathtub to slowly absorb the water from Tang Xin's body without damaging her skin.

(You should be able to understand it, right?)

When Li Tian explained the principle of this kind of thing, Logan immediately understood it, because she seemed to have really learned it when she was in junior high school. The saturation of salt seemed to be a number. She didn't know whether it was thirty-six or thirty-seven.

It's been so many years.

Thirty-six means that in one hundred grams of water, thirty-six grams of table salt can be dissolved. If it exceeds this weight, it will not dissolve and will precipitate inside like crystals.

Although I thought about it, after all, it is something in a textbook. Who can apply it to real life? Tang Wan was also very good at studying before, so he never thought of this, even though Li Tian had already taken out the salt.

This is the gap. Maybe Li Tian has not learned anything, but what he has learned can be used at any time.

After finishing the story, Li Tian said: "Well... if your body can still hold on, can you go and make me some food?"

It was already twelve o'clock at noon, and Li Tian was very hungry. This kind of thing requires endurance.

When Tang Wan heard this, he immediately said: "Okay, I'll do it now. There are some ready-made vegetables and meat in the kitchen."

Seeing Tang Wan turn around and walk outside, Li Tian suddenly called out to her: "Well... there should be no salt in the kitchen. You need to go out and buy some. Also, the department store closest to us is gone too."

There is no salt, so you can't just scoop some water from the bathtub to cook. Thinking of that scene, Li Tian felt that his appetite suddenly disappeared.

"Well, I'll go out and buy some."

After resting for more than an hour, Logan felt quite energetic, so it shouldn't be a problem to go out and buy something.

After getting in the car, Tang Wan suddenly felt that the world was so peaceful and there were no worries at all. It seemed that as long as Li Tian was by her side, all the worries would disappear automatically.

When passing by Li Tian's door, Tang Wan found that Wenwen was playing with Wang Ma in the yard. She originally wanted to shout, but thinking of the situation at home, Tang Wan held back.

As long as it's safe, I don't have to worry about Wen Wen.

As for those two people...what do you care about their life and death?

Logan made up his mind that he would never let those two guys disturb his life again. Ever since they were shameless enough to betray his sister, they were no longer his parents.

Do you owe them? Yes, you owe them a life, but how many things has Logan done for them over the years? Even if you can't pay it all, Logan won't feel too guilty.

It's them who have wiped away all the little affection, until now.

Because the nearby department store ran out of salt, Logan ran a little further. There were still some dirty marks on her clothes, but she didn't care anymore.

I bought some vegetables and meat by the way, and Tang Wan decided to make a good meal to reward Li Tian.

When she returned home and saw Li Tian still sitting there, Logan felt extremely comfortable. She had been really exhausted these days, and finally, all the pressure in her heart disappeared.

This man can always resolve all difficulties and troubles.

If...if no accident happened, would the two of them have...

On that day, Logan was already ready for everything, if those two people hadn't suddenly caused trouble.

He must hate himself now, right? But... if there is no more intersection in the future, then should I... give him one chance?
