Niu Deyu was a little confused for a while.

"Don't worry, you go and help Mengzi bring me the lime, and when the pot starts a fire at night, I'll let you see what we make money on in the future."

Hearing him say this, Niu De's hanging heart suddenly let go, and he happily went to find Niu Meng to prepare things.

Night fell quickly, and when Niu Dehao and Niu Meng came to the courtyard of the Xiao family, Xiao Feng had already set up three cauldrons, and added a lot of firewood under them.

"Big cow, you pour a big bucket of that lard into this pot."

"Mengzi, go get five buckets of water, put them in the pot here, and then bring me all the ashes from the kitchen."

After instructing the two of them, Xiao Feng walked straight to the chicken coop and took all the more than 100 eggs collected in the past two days to the cauldron.

The things were quickly prepared, Xiao Feng instructed Niu Dehao to add materials such as plant ash and salt brine to the cauldron on the left, and at the same time instructed Niu Nan to gradually add plant ash, salt and brine blocks, salt and lime to the water.

Xiao Feng found two long wooden sticks and handed them to the two of them respectively.

"Big bull, fierce son, you must stir the things in this pot evenly, don't be sloppy!"

Niu Dehao and Niu Meng are originally Zhuang households, and it is not a problem to do this bit of hard work, in the whole heating process, Niu Dehao and Niu Meng seem to be incarnated as robots, and they have not taken a break.

Seeing that the ingredients in the pot had almost reacted, Xiao Feng instructed the two to remove the flames in the furnace, and added a small bag of spices to the pot next to Niu Dehao.

"Big Niu, you take out all the things floating in this pot, I have dug small pits in the ground over there, you pour them in."

Da Niu nodded, and fished out the prototypes of those white jade soaps little by little.

At the same time, Niu Meng's side was almost busy.

"Mengzi, go get the pickle bar."

Xiao Feng stirred the ashes in the pot, and felt that the viscosity was very good, so he picked out some with a spoon, took an egg and carefully smeared it.

Seeing that the ash outside the egg did not fall even if it was suspended in the air, Xiao Feng wrapped it with waste rice husks with confidence.

"Brother Feng, what are you doing, it looks like it's fun."

Where has Niu Meng seen such a rare thing as a pine flower egg, and he also learned from Xiao Feng's example.

Xiao Feng smiled.

"Actually, it's nothing, it's just to make some pine eggs."

Lin Shuiyao passed by and suddenly became interested when she heard the word Songhua Egg.

"Husband, what is a Songhua egg?"

The ancients had no knowledge of chemistry, and Xiao Feng didn't plan to explain it to them from the principles of chemistry, so he thought about it and made up a more acceptable statement.

"Songhua eggs, it's a kind of dish, it's excellent with wine, and when the time comes, it's the first one for you to taste!"

Lin Shuiyao was overjoyed, and had already thrown yesterday's unhappiness out of the clouds.

"Then, husband, we can make up our minds, and we can't go back!"

Xiao Feng nodded.

"Big brother, I've put everything in the dirt pit here, is there anything else to do?"

Hearing Niu De's voice, Xiao Feng hurriedly ran over. He remembered that when he was digging those small square pits, he deliberately used a ruler to measure them, so that the quality of each piece of soap was about the same after it was made, but Niu Dehao completed it in such a short time, I am afraid that it would be ......

However, after Xiao Feng came to Niu Dehao's side, he found out that Niu Dehao not only has a good strength, but also sits on the bench with a bare ass to do these fine jobs - there are boards and eyes.

"Not bad, not bad."

As he spoke, Xiao Feng picked up a piece of white jade soap that had solidified almost the same, and in order not to destroy the original shape of the soap, he simply put it back and shoveled down the small square pit with a shovel.

After waiting for a while, the piece of soap that Shan took out completely solidified and became white and yellow, quite a warm feeling of mutton fat and white jade.

Feeling that the name of the soap did not highlight the lofty temperament, Xiao Feng took a knife and engraved the words "white jade soap" on the first piece of soap.

"Big brother, what do you mean at this moment?"

Niu Dehao is not very literate, he only recognizes the white characters on it, and the other two only know him.

"White jade soap, that is, this thing we made is a fight with mutton fat white jade."

Niu Dehao's eyes lit up after hearing this.

He didn't know the value of white jade soap, but he had more or less heard of the price of mutton fat white jade. Not to mention priceless, but also priceless!

Seeing that the white jade soap was such a treasure, Niu Dehao took the spoon and returned to the pot to stir repeatedly, trying to get another piece of white jade soap.

"Eh, what a waste, how can ten catties of lard make such a little white jade soap!"

In fact, Xiao Feng only made more than 30 pieces of white jade soap on purpose, he did not make all the lard into white jade soap, but kept some of it to make other things.

"Big Niu, I remember that we still have some useless sulfur in our warehouse, you take him to the yard for me."

Niu Dehao ran over in a few steps, and then took the jar and ran out in a few steps.

"Big brother, I brought you something."

At this time, Niu Dehao's eyes were already attracted by the broken lid in Xiao Feng's hand.

"The last stove, light the fire."

After giving the order, Xiao Feng sealed the leaky pot lid mud on the stove, leaving only a place to add firewood.

Immediately afterwards, Xiao Feng brought the thick reed pole that had been prepared a long time ago. An air guide was made, and on the other side of the pipe were two water tanks that were interconnected with each other.

After adding a part of the sulfur to the furnace, Xiao Feng immediately instructed Niu Dehao to seal the place where the firewood was added, leaving only a small ventilation hole.

After a while, the pipe connected to the small water tank began to ventilate, and slowly pushed the upside-down tank up.

When the water tank was lowered, Xiao Feng asked Da Niu and Niu Meng to add some sulfur to it.

This was repeated five or six times before the sulfur was finally gone, and when the small water tank was picked up, Xiao Feng smelled the sour smell in the water tank, he was as happy as a child.

"It's done! Fierce, quick, boil lard? ”

Niu Dehao and Niu Meng didn't understand a single step from coming in to the present, so they simply abandoned thinking and mechanically obeyed Xiao Feng's orders.

After the lard was burned, Xiao Feng carefully added the sour water and salt brine in the pot to the lard.

After a while, the lard became more viscous, and even if the fire had not been heard, Niu Meng could not stir it a little.

Xiao Feng asked Niu Meng to rest, and Niu Dehao poured the contents of the pot into a dozen bamboo tubes, and then took a few cotton ropes more than a foot long and put them into the bamboo tubes, leaving only one thread outside.

Niu Meng looked at the shape of the bamboo tube and the thread that was left behind, and a flash of inspiration occurred for a while.

"Brother Feng, why do the things you make look so much like candles?"
