【Soaking potassium permanganate solution for 24 hours can remove the remaining toxic substances in the crystal nucleus.】

The Doomsday Survival Newbie Guide is marked with bold fonts.

The crystal nucleus purification method that countless teenage mice in the previous life failed to crack was so simple?

A large box of potassium permanganate tablets cost a few dollars. They are common sterilization and disinfection drugs. They can also be used as water purification tablets when necessary.

However, the professional talents and equipment that were able to make chemicals in the last life were monopolized by major bases, and ordinary people could not buy them even if they had money.

Fortunately, I suffered from water pollution in my previous life, so Lu Sheng stocked up a lot of goods at a low price when he was stocking up. Unexpectedly, by accident, there are still uses of this.

Although the system signed in to an essence extractor, Sun Tiantian and the others had to give a reasonable explanation on the surface.

Lu Sheng took out a bottle of potassium permanganate disinfection tablets from the space, took out the washbasin and poured hot water into it, and threw it in.

The water in the basin quickly turned purple and red. Lu Sheng put all the crystal cores into the water, and a trace of dirty black substance immediately oozed out of the water surface.

A scent of rotten smell rose from above the washbasin.

Lu Sheng pinched his nose and found another basin to cover it, which blocked the odor.

All the collective property was disinfected with potassium permanganate. With the remaining space, Lu Sheng grabbed a few of them and threw them into the essence extraction machine.

Cruff.

Press the start button, and after a few crisp crushing sounds, a small bunch of transparent liquid flows out of the machine.

Lu Sheng used a cup to connect it, and the five primary crystal cores were exactly about 100ml.

I lit it with the tip of my tongue, and it was a bit cold and sweet, like rock sugar water.

"I won't squirt after drinking this thing..." Lu Sheng stared at the sweet water in the cup.

Forget it and don't care.

He raised his head and let out a mouthful of stuffyness.

The little sweet water slid into his throat, and a refreshing feeling that moistened the lungs.

Lu Sheng felt that the fatigue in his body was wiped out, as if there was a constant stream of energy injected into the blood.

Try to release the power.

It's so cool!

The huge electric ball formed by the fingertips frightened Zhuang Zhuang and shrank behind the sofa with his tail.

Before each release of electric power, Lu Sheng had to accumulate energy for a few seconds, and after releasing the power, his body would feel a brief sense of fatigue.

But now I have drunk a glass of sweet water, and my waist will no longer be sore and my legs will no longer hurt. I just squeezed it with one hand and I will have hundreds of thousands of volts.

You have to eat at least 10 wild Pikachus raw to have this kind of electric system enhancement.

Lu Sheng silently placed the essence extractor in the safest and most eye-catching position in the space. In the future, it depends on it to drink soup or eat meat.

Put away the remaining crystal cores in the space, and Lu Sheng hugged Zhuangzhuang and climbed onto the bed.

One cup a day is just right, and it is easy to get nosebleed if you make up for your energy once.

...

The next morning, Lu Sheng prepared breakfast early in the morning and served it to 402.

Braised beef noodles, the noodles are vigorous and chewy, and the toppings are fragrant and glutinous.

While Sun Tiantian and Xiao Yu were eating noodles, they poured the purified high-level enhanced serum into Sun Tiantian's juice.

There is also a superpower conversion book that killed the small alien species, and another piece of chocolate was quietly put into Xiao Yu's hot milk.

Before the meal was finished, the effect of the two people was rising.

Sun Tiantian was the first to go back to the bedroom. Xiao Yu held her eyelids and insisted on brushing the bowl, and fell asleep directly on the sofa.

Lu Sheng hugged Zhuangzhuang and waited anxiously for the whole morning, and the two of them woke up slowly.

Fortunately, Sun Tiantian awakened the Frost superpower, and Xiao Yu also awakened the water-based superpower under the influence of the superpower conversion book.

Lu Sheng: "..."

This world really belongs to the love brain.

After the end of the world, power and speed abilities will have certain advantages in the early stage, but as the number of crystal cores is acquired, the elemental system and natural system will become powerful late-stage professions as the ability level increases.

The frost superpower is a very strong lineage in the elemental system. It is even more powerful in an environment with water, and can exert 200% of its strength.

The two conjoined babies, Sun Tiantian and Xiao Yu, are just complementary to each other.

There is also a hidden benefit. After the frost-type psychic awakens, the body's adaptability to low temperatures will be far more than that of ordinary people. At least in the current extreme cold period, Sun Tiantian can survive a little easier.

"We won't be short of water in the future, right?"

Xiao Yu controlled the small water ball in his palm and had a lot of fun with Zhuang Zhuang.

Zhuang Zhuang scratched the water ball with one claw, drenched his head and moaned towards Lu Sheng.

"The superpower requires a certain degree of proficiency, so let's save some water first." Lu Sheng put on his gloves and hat, "Let's save some first while the snow is clean up on the floor."

The three of them brought all the large basins in the dormitory and wrapped them tightly.

There are already two or three groups of people on the top floor filling up snow and water, and Jiang Lan is also there.

Fortunately, the imperial capital is more than minus ten degrees Celsius in winter, and some students living in the school have two winter clothes.

The snow on the roof is white and soft. It is put in a basin and taken into the house for a while and then becomes water purified.

Lu Sheng and the other two were holding large basins and shoveling snow hard. Suddenly, heart-wrenching crying came from downstairs, which made people's ears numb.

"It seems like Bai Shuangshuang and the others..." Sun Tiantian leaned her head down and glanced.

An eight-handed Beijing Jeep was parked downstairs, and Su Zicheng and Li Xiang were lifting people down from the back seat of the car.

"Oh, isn't this Miss Hua? I haven't seen this for a few days." Xiao Yu still remembered that Bai Shuangshuang instigated someone to come for trouble last time, and mocked him sarcastically.

One of the girls who were carried out was Bai Shuangshuang, and the other was familiar with her and couldn't call her name. Both of them were dressed in disheveled clothes and had messy hair. They cried and howled when they got out of the car.

Bai Shuangshuang had already injured one leg and limped when walking. Now her posture looks even worse. She didn't take two steps and seemed to fall down.

The other one was not much better, and walked into the building with red dots dripping from behind.

Su Zicheng and Li Xiang chatted with the man in the cab with a flattering look on their faces, and after a while, they threw out a few bags of rice bricks from the car window.

"Have you been on the dock?" Xiao Yu asked in his head.

In the end, Jiang Lan helped the three of them to solve the questions.

"Su Zicheng and Li Xiang don't know why they got the big brother who collected protection fees outside the school. In the past two days, they have sent several girls in the building."

"Those people are all beasts, and they are playing with the girl to death." Jiang Lan looked complicated and silently wrapped her collar tightly. "The two people came back yesterday, and there was no good piece of meat on their bodies. It is said that the pool was covered with blood when they went to the toilet."

"Let these beasts play for a few hours before they can change 2 bags of rice bricks, and they also have to take 30% of them for Su Zicheng and Li Xiang."

Lu Sheng sneered, and unexpectedly, Su Zicheng was so sensible that he would become a madam in the end of the world.

"Is that person in the car the eldest brother?" Sun Tiantian asked, pointing to the short and fat young man in Beijing Jipu.

"Yes, it's him." Jiang Lan nodded.
