Wang Shu used the star to light up all the 9 disciplines of the talent tree.

A number of warm currents surged from his eyes, ears, mouth, and nose, and finally met above his head.

"Hmm~ so comfortable. Wang Shu couldn't help but hum the waves again.

This time, the refreshment is much stronger than the last time, and it lasts a little longer.

Wang Shudun felt that his ears and eyes were clear, and his whole brain was in a state of excitement, and he had never been so awake.

Continue to pull down, and part of the original gray area of the talent tree is visible.

The mid-level talent tree is no longer a basic discipline, but some comprehensive categories.

For example: Financial Engineering, Reconnaissance, Information and Computing Science, Space Science and Technology, Mechanical Design, Manufacturing and Automation, Measurement and Control Technology and Instruments, Polymer Materials and Engineering, Network Engineering。。。。。。 Wait a minute.

Wang Shu is full of infinite longing and confidence for the future, but also deeply melancholy about reality.

The hard-earned medals were used up in an instant.

and the thousand taels of gold that Old Madam Shen rewarded, now counted, and there is less than half left.

There is no way, if you want to gain in the future, you must pay now.

raised a hundred people, and only paid a salary of one hundred taels per month, plus daily food and clothing, the rest of the money could not last long.

You have to find a way to make money quickly.

However, money is hard to earn, and is hard to eat.

What should we do?

Wang Shu couldn't sleep sadly, so he simply went out for a stroll.

Month, so white.

The night is so quiet.

"Boom!"

What was that?

It seems to have come from the Huai'an house.

Wang Shu rushed in, this was the first time he had entered Huai'an's bedroom.

A room full of bottles and cans, exuding a pungent smell, Huai'an was sitting at the table, pouring this cup into that cup.

"You're sick!

"Or else?"

Huai An replied without raising his head.

Wang Shu was speechless, he didn't seem to provide him with a special place to do experiments.

"Don't do it, don't do it, I'll arrange a lab for you tomorrow. ”

With that, Wang Shu stepped forward to stop Huai'an.

Nitroglycerin?plant ash?

It is impossible for Wang Shu to recognize these things, but why did he only glance at them and have names in his mind?

It must be the chemistry knowledge in the talent tree in the system that works!

Wang Shu felt a little better.

"Add some egg whites and rust and try it. He couldn't help but proudly point out for Huai'an.

"Go away, go away, don't make a mess. Huai'an failed in the experiment and was distraught, how could he be in the mood to listen to his nonsense.

Wang Shu left.

Instead of obediently leaving, he is going to find egg whites and rust to prove himself.

It worked!

In the middle of the night, the two of them successfully blasted on a wasteland.

With the addition of a certain percentage of egg white and rust, the new explosives are more stable and more explosive than the ones he developed before, and the blasting power is also stronger.

Huai An looked at Wang Shu in a daze, I don't know if he worships him, or does he worship him?

"Ding!

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

"Master, you... How do you know?"

Huai'an's attitude towards Wang Shu is simply a 720-degree change, and it is completely the attitude of the little brother to the eldest brother.

"Don't be obsessed with brother, brother is just a legend. ”

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

Wang Shu can fall asleep now.

Because he has already figured out how to make money.

Of course, it was Huai'an who inspired him.

He wants to get ahead of the day soon, and he is anxious to lead everyone to get rich together!

He had just seen nitroglycerin when he had an inspiration.

He thought of soap!

To make explosives in Huai'an, nitroglycerin is indispensable.

Nitroglycerin is made with nitric acid, sulfuric acid, and glycerin.

Making glycerin is made with lard and caustic soda.

Another product of glycerin is soap.

Glycerin is the most basic material for making explosives, so Huai'an only made a lot.

That said, there are also many other discarded products.

Tomorrow, the discarded soap will be remelted, solidified, cut into squares, and put on paper. It's a waste to a treasure.

He felt that he was too genius, and he just wished that the sky would be bright so that he could tell everyone the news.

。。。。。。

Early in the morning, Huai'an obeyed Wang Shu's instructions and moved all the remaining waste materials for making glycerin out of the house and poured them into a large iron pot.

And he commanded two men, one to light the fire, and the other to stir it.

Next, pour the hot soapy water into the square stone trough in the door and wait for it to solidify.

In order to speed up the cooling, Wang Shu ordered several people to stand in different directions and fan the wind together.

"Master, the water in that pond has cooled down and turned into hard stones. A disciple rushed to report.

"Let's go, let's see. ”

In the stone trough is a slightly transparent giant soap.

Wang Shu ordered someone to cut him into small pieces the size of a palm.

In my hand, I was very satisfied.

"You. Take off your clothes. Wang Shu pointed to a green-clothed disciple and said.

Wang Shu personally demonstrated, soaked the clothes, evenly applied the soap in his hands, and then rubbed and washed.

Well, Wang Shu looked at the clothes he washed out with the soap he made with his own hands with satisfaction.

The crowd was amazed.

Your clothes turned out to be blue?

I thought it was green.

"Tomorrow, each person will work in groups of three, and go down the mountain with soap to sell. ”

Each bar of soap costs one or two pieces of silver.

In addition to the fixed tael of gold every month, I rewarded him with a penny for every bar of soap sold.

The disciples exploded.

If I can sell a bar of soap every day, it won't be long before I have money to get my daughter-in-law, right?

Everyone laughed.

Day 2. In the streets and alleys, the disciples of Hongyun Dangmen wandered in groups of three.

"Do you want soap?"

"Something, go away. ”

The first day of school was not smooth.

The people are not very receptive to new things, and they don't know what they are.

Don't be discouraged, just because you don't buy it doesn't mean that our stuff is bad.

Tomorrow, each person will take a piece of dirty laundry and do the laundry at the street show.

On the third day, in the streets and alleys, the disciples of Hongyun Dangmen squatted in groups of three and performed washing clothes in the streets and alleys.

Everyone also has a line.

There are even people who shout, you buy soap and I do the laundry.

The event attracted a lot of housewives.

They came with a large pile of sheets and quilts.

The streets and alleys are full of disciples washing clothes.

"Fortune Dangtoumen changed its name to the laundry gang. ”

At the end of the day, the disciples were so tired that their backs and legs hurt. But happily, the effect is still good.

One hundred pieces of soap, half of which have been sold.

The next day, before they could go out, someone came to the house. Sold out instantly.

The sales volume has risen, and Wang Shu has time to prepare raw materials.
