What is Hu Changyi doing? What else can he do? Making soap! He has been busy fighting and doing military industry for more than two months, and this time he finally took some time to create some livelihood products...

Oh no, what is making soap? Soap is just a by-product. Our parents are making glycerin! Well, it is making glycerin!

Glycerin is a good thing. Adding nitric acid is nitroglycerin, which is a highly explosive with extremely powerful and sensitive nature. Of course, nitroglycerin can also be used as a relief drug for angina pectoris.

Just when Zhang Wanhe and Li Yunlong looked at the room where Hu Changyi was, Hu Changyi had just completed the saponification reaction between lard and sodium hydroxide. A large piece of pure soap has been made from the oil pan for saponification reaction.

Transferred into a pottery basin.

Then, he added the fine bamboo charcoal powder to the basin and stirred carefully. While the soap has not yet solidified, pour it directly into the mold made of the elm wood board. The board surface is 4 cm deep, 30 cm wide, and 50 cm long

The centimeter rectangular depression plate surface can be divided into pieces after solidification.

Hu Changyi's plan is to divide it into large square soaps with a height of 4 cm and a width of 5 cm and a length of 10 cm. As for whether you think the shape is not good-looking? Some are good to use, and you are still picky? Didn't we add bamboo charcoal?

It is said that bamboo charcoal can absorb dirt in the deep skin, how good!

Because Hu Changyi didn't get much lard this time, he only got two plates and there was not much left. He didn't waste the rest, and some small single molds were on the side

Go up, pour it in and finish it.

"When you succeed, you will never do it yourself!" Hu Changyi stood up and stretched, turning around and looking at the oil pan.

Or, now you can't call it a oil pan. After all, the oil has completed the saponification reaction. Now there are some turbid oils, soapy substances, alkaline waste liquid at the bottom layer and glycerin left in the pot.

Skim out the turbid soapy materials separately and put them in the previous basin, add some brine (this brine is not the brine for boiling braised pork, it is the brine of tofu in the brine. There are so many in Yuncheng Salt Lake.) Stir and let the brine

The reaction of hydrochloric acid and oil can result in the second by-product of this time - wax.

These waxes are good things, which can be made into candles for lighting, and can also be used in the production of arsenals. The production of a soldier workshop requires wax, whether it is wax sealing or lost wax fine casting.

After finishing the wax, Hu Changyi turned his attention to the remaining waste liquid. Well, there will be glycerin in it. You only need to remove the alkali liquid, dilute and clarify to obtain glycerin sweet water, and then filter out the glycerin.

With glycerin, there is still some nitric acid in my hand, and the rest is to get nitrified glycerin.

Of course, Hu Changyi stopped at this point. For nothing else, he had heard Li Yunlong's loud voice for a long time, but he didn't have time to go out to see him, so he could go out now. As for glycerin? The thing is here, at any time

Can you come back?

"Minister Zhang, Deputy Commander Li!" Hu Changyi went out to the yard, and Zhang Wanhe and Li Yunlong were waiting.

Zhang Wanhe came here this time to supervise the assembly and production of grenades. As a person in charge of logistics, or a poor army like the Eighth Route Army, Lao Zhang felt miserable.

As for what the grenades made by the guerrillas should be handed over to Zhang Wanhe to decide? Isn't this normal? What did the guerrillas have? Hu Changyi's skills and the labor force of the big guys. The rest, cast iron, glass, and copper wire

...Don't these things be bought by the organization?

Besides, the guerrillas can also intercept some grenades for their own use. The people who work have an extra allowance of two yuan, and the usual material guarantee is sufficient.

With this condition, what else is there to be dissatisfied with? Can Lao Li’s 772 group be eaten every now and then?

"Hahaha, Changyi, you don't know. I didn't fall asleep all night after receiving the report of you reloading bullets yesterday. Lao Zhang is so happy! We can reload bullets, fighting on the front line

Comrades can also have an ammunition supplement!”

"Oh, you don't know. Although we won the anti-siege this time, the bullets seized were not as many as those in the previous ambush! Even calculating the consumption of ammunition, it was still not enough to make ends meet! Lao Zhang, I was worried!

”

"Now, with your supplements, we can be more abundant when fighting!"

"Oh by the way, I heard that during the anti-siege, you kid were determined to go to the front line to kill the enemy. How could this work? You, just do production with peace of mind, build bullets, grenades, and fight with peace of mind.

Let a rude man like Li Yunlong do it! Is it, Li Yunlong?"

When Zhang Wanhe saw Hu Changyi, he walked over and held Hu Changyi's hands and said. His happy look was the same as the old father who saw his son getting married. Well, it would be better not to be the new wife's house.

The kind of thing that takes a bride price and pays a house for a bride.

"Yes, yes! Let's do the war, and you kid will have a safe production!" Li Yunlong agreed.

"Deputy Commander Li, do you look down on my marksmanship or my grenade launcher skills? We can do it when fighting!" Hu Changyi said to Li Yunlong.

"Okay! It must be OK, I didn't say you can't! But how many things have you made since you opened your secret? Put you in front of you to fight with the Japanese, who do you think will do this?" Li Yunlong said.

"That's Changyi, you can do production with peace of mind! They are all working for the anti-Japanese war, but the division of labor is different! By the way, wasn't your speech in Yaogou Village some time ago? Every time we create a qualified one

With grenades, several Japanese may have killed them on the battlefield!”

"Don't you still want to build a gun that really belongs to us, our cannons, and even our own plane tanks? Look, now that the bullets are coming out, the guns and cannons are not far away!"

"Oh by the way, I heard that you want to go to Licheng to establish a base? The organization has carefully considered your ideas. Now the comrades from the advance team have sent you to find a suitable place!"

"So, just wait with peace of mind. After choosing the place, we will move over! You know, Licheng is not our place now, and the bare-headed principal has been idle in our range of activities. We have to wait.

It's a chance!" Zhang Wanhe spoke very quickly and never gave Hu Changyi a chance to reply.

"Ahem...Minister Zhang, Deputy Commander Li, I understand what you mean, don't worry, I completely obey the organization's arrangement! When the anti-siege was against the siege, I was so anxious that I watched everyone beat them to death!

Oh by the way, do you want to see our reloaded bullets? Let's try it out if we fire two shots?" Hu Changyi said.
Chapter completed!
