Nitroglycerin?plant ash?

These two names suddenly popped up in Wang Shu's mind.

It seems that he accidentally caught a glimpse of it when he was fighting with him in Huai'an's room just now.

Those things Wang Shu couldn't have known.

But how come you just glance at it at random and have a name in your head?

Talent Tree!

Yes, it must be the chemistry knowledge in the talent tree in the system that works!

Don't feel too good about being a top student.

At this time, Wang Shu felt a little floating.

He returned to Huai'an's bedroom.

He found the bottles and jars of unknown liquid on the table, and he could name and use it. Huai'an's experimental principles and operating procedures, including his failures, are also well known.

"Add some egg whites and rust and try it. Wang Shu pointed out like a master.

"Go away, go away, don't make a mess. ”

Huai'an had just failed in the experiment, and he was distraught, and he was in no mood to listen to his nonsense.

"Ding!

Received Huai'an's dislike of you, negative sentiment value +1+1+1+1. ”

"How dare you think I'm causing trouble? Wait, and I'll let you kneel and worship in a while. ”

Wang Shu turned his head and left.

He didn't leave angry.

With his cheeks, of course it can't be.

He was looking for egg whites and rust.

"Boom!"

"Ryo!"

"Smack!"

After the head of the courtyard,

On a wasteland,

A cloud of dust and smoke with a deafening sound exploded in front of my eyes and lingered for a long time.

The experiment was a success!

Huai'an stared at Wang Shu in a daze, staring all the time, and there seemed to be something shiny in his eyes.

After adding a certain proportion of egg white and rust, the new explosives are more stable and have stronger blasting power than those previously developed by Huai'an.

"Ding!

Receive Huai'an's extreme worship of you, positive sentiment value +1+1+1+1+1+1+1+1+1. ”

"Sir, how did you know to add egg whites and rust?"

This seems to be the first time Huai'an spoke, let's call the boss.

It seems that "you" is still used?

"What is this? just a drizzle. ”

Wang Shu said, showing a mysterious smile, and left.

Liuhuai'an was alone in the wasteland.

Wang Shu can fall asleep now.

Because he has already figured out how to earn his first pot of gold.

He was inspired by nitroglycerin, the main ingredient in explosives.

To make nitroglycerin, you need a lot of glycerin, and when you think of glycerin, soap naturally comes to mind.

The people of the Heavenly Dome Continent are currently taking plant ash for laundry, and the principle is that the potassium carbonate in the plant ash is alkaline, which can remove oil stains.

The decontamination capacity of plant ash is limited, and it is necessary to repeatedly and vigorously beat it with a laundry pestle when washing.

For them, laundry is a time-consuming and labor-intensive task. Therefore, ordinary people wear dark-colored coarse cloth clothes and minimize the number of laundry visits.

Ordinary women are unattainable for wearing light-colored clothes. At that time, wearing light-colored clothing was often a symbol of nobility.

If soap is popularized, people only need to gently rub when washing clothes, which greatly reduces the burden of laundry. When people who love beauty buy clothes, they no longer have to give up their favorite colors because they are worried about the cumbersome laundry.

As soon as soap comes out, it will be sold out!

Huai'an uses the traditional method of mixing lard with caustic soda and heating to refine glycerin.

The glycerin floating in the upper layer is taken away, and all the substances in the lower layer are collected as waste in a large vat, and when it is full, it is pulled away and discarded.

This waste material in the vat is precisely soap!

Reusing waste materials and turning waste into treasure, Wang Shu feels that he is simply too genius.

"Get up, get up!"

Before the rooster crowed, Wang Shu had already knocked on the door one by one, waking up all the disciples.

The disciples gathered in the courtyard with sleepy eyes.

He divided his disciples into four teams, namely the fire squad, the stirring squad, the cooling squad, and the cutting squad.

。。。。。

"Yes, yes... ”

Wang Shu held the finished product in his hand and was very satisfied.

"What is the boss doing?"

"Are you cooking for us?"

"It doesn't look delicious. ”

。。。。。。

All the disciples were confused, and they didn't know what kind of medicine was sold in the gourd of the master.

"You, take off your clothes. ”

Wang Shu suddenly pointed to a disciple in dark green clothes and said.

"Ahh What for?"

The dark green disciple clasped his hands on his chest, and his face was flushed with shame.

"What do you think, I'm going to do your laundry. ”

Wang Shu ordered all the disciples to gather in a circle to see how he washed his clothes.

He soaked his clothes in a basin, spread the soap evenly, rubbed it, and washed it.

"That's it!"

Wang Shu shook the washed and wrung out clothes, the clothes were clean and bright in the sun.

"Why did the clothes change color?" asked one of the disciples.

The dark green clothes just now are now blue.

"He was originally blue. The stripper said embarrassedly.

In fact, the clothes themselves are indeed blue, because they have not been washed for a long time, the yellow oil stains accumulate more and more, and the blue clothes are green.

"You've never washed this garment before. Wang Shu frowned.

The disciple who hugged his chest smiled embarrassedly.

"What kind of artifact is this?"

"Yes, the head didn't beat it with a laundry pestle, just rubbed it a few times, and the clothes were so clean?"

"The clothes were as good as new. ”

。。。。。。

"Master, what the hell are you?"

Huai'an rubbed his hands on the side, his waist was 90 degrees, and he saluted and asked.

Xiao Mengmei and Mo Yi were so shocked that their eyes were about to fall to the ground, and they didn't know what kind of wind Huai'an was smoking.

After last night's incident, Huai'an has a lot of respect for Wang Shuna.

Now Wang Shu is in his eyes, it is an idol-like existence.

Wang Shu saw the reaction of Xiaomengmei and Mo Yi, and his vanity was greatly satisfied, and he couldn't help but think: "Sooner or later, one day, the two of you will be like this." ”

"It's soap, just make a little bit to play with. ”

"Master, you are so powerful, you are the first person in my life to serve!"

"Ding!

Receive Huai'an's five-body throw, positive sentiment value +1+1+1+1+1. ”

"It's drizzle, it's just drizzle. ”

The more this person is in front of the people who appreciate you, the more he likes to behave perfectly (outfit 13).

"Today's task, laundry!" Wang Shu said to his disciples.

"It's amazing. ”

"It's so easy to use. ”

"I've never washed my clothes so cleanly. ”

"Yes, the point is that it doesn't take much effort at all, and with a gentle rub, the dirt will fall off. ”

The disciples were chatting excitedly while washing.

"Ding!

Received Zhang Tiancai's admiration for you, positive sentiment value +1+1+1+1. ”

"Ding!

Received Li Genji's admiration for you, positive sentiment value +1+1+1+1. ”

"Ding!

Received Zhao Si's admiration for you, positive sentiment value +1+1+1+1. ”

。。。。。。

Wang Shu sat paralyzed on the Taishi's chair, watching the clean and new clothes floating in the wind all over the courtyard, and his heart was happy.

He had already seen himself rolling in the pile of gold ingots.

Tomorrow, let them go down the mountain to sell, the scene is not too hot, will it be because of the soap grabbing?
