The workshop area officially started construction in the cold winter, and Xiao Ming also successfully added more than 900 mouths to eat. In addition, the new recruits were about to enter the camp, so there were about 3,000 mouths to eat.

Such continuous consumption of silver made Xiao Ming feel very stressed, and at present, he has no way to get rich quickly except for business.

So whether it is preparing for one's own business or using the Wang and Qin families to make money, the money is always unaffordable.

After arranging the slave affairs, Xiao Ming went to the Wang family and talked about the issue of trade with the barbarians.

"Your Highness, our Wang family dare not bear such a big charge." Before Xiao Ming finished speaking, Wang Chengchou knelt down with a "gudong". Wang Shijie also sweated on his forehead and his whole body was as if he was slapped.

They received the news that the emperor and the queen both gave the King of Qi silver, and the news from Chang'an also proved from the fact that the emperor and the prince seemed to have the intention of relying on the King of Qi.

This prince who no one asked has a different meaning than a prince who was in charge. They used to dare to bully Xiao Ming's ignorance.

But now the forces behind Xiao Ming have to carefully measure the pros and cons. If Xiao Ming convicted the Wang family of affair with foreign enemies because of this, the Wang family might have been killed.

Even if the Wang family is powerful and not afraid of the King of Qi and the Qingzhou army is not afraid of it, there will be the emperor and the prince. It will only be a matter of time when the army moves and the Wang family will be destroyed.

Xiao Ming was a little helpless. This was the first time he saw a fear in Wang Chengchou's eyes. It seemed that Xiao Wenxuan and the Queen gave the money very promptly, making him feel powerful.

He said: "Mr. Wang, brother Wang, get up, I am not here to punish me. I believe both of you know that many cattle and sheep from Huyantuo tribe were frozen to death on the grassland this year. Now barbarian scouts frequently investigate the situation of the defenders outside Cangzhou City. You probably understand this thought."

Wang Chengchou wiped the sweat beads on his forehead and said with a smirk: "Your Highness, I have heard of this. This cattle and sheep has indeed frozen a lot. The barbarians on the grassland usually eat goat milk and beef and mutton. The cattle and sheep have frozen to death and have no cubs. After spring, there will be no cattle and sheep to be put away. At that time, the barbarians will go hungry."

"The same is true for the Captain Lu, so there is only one simplest way to solve this problem and avoid the barbarians' siege of Cangzhou." Xiao Ming said.

"Please speak with your highness," said Wang Chengchou.

Xiao Ming did not say directly, because he didn't want to bear such a crime. He made indirect attacks and was about to give Wang Chengchou a pit. He said, "If the cattle and sheep die, the merchants naturally don't want it, but the meat oil of the cattle and sheep can be used to refine soap. If Wang Yuanwai uses grain to exchange for meat oil at this time, what would happen to the barbarians? The barbarians only want beef and mutton. Meat oil is not valuable to them. If these cheap meat oils are transported back, large batches of soap can be refined, what would happen to Wang Yuanwai?"

Wang Shijie and Wang Chengchou looked at each other with a strange look.

"Okay, I will say this, and I still hope that Cangzhou will be safe." After saying this, Xiao Ming left the Wang family compound.

Wang Shijie immediately stood up and sent Xiao Ming out. After a while, he turned back and said to Wang Chengchou: "Dad, your highness is right. If you use food to exchange for meat and oil at this time, it will definitely be a huge profit. Moreover, your highness's words seem to encourage us to do it."

Wang Chengchou was still kneeling on the ground at this time, and slowly got up and sat down on the chair. "This King of Qi is really unpredictable. He does not want to bear the charge of affair with foreign enemies, and wants to resolve the danger in Cangzhou, but our Wang family cannot take this risk."

"What should I do?" Wang Shijie asked.

"Hehe, there is no way. Why does our Wang family need to take action on this matter? You just need to let the businessmen in Cangzhou say that our Wang family purchases meat oil and then spreads the method of using grain from Huyantuo to exchange meat oil. Are you afraid that no one will go? At that time, we were just spending more money, which was better than taking on this crime. I don't want to have a handle in the hands of King Qi like the Qin family." Wang Chengchou said while twisting his beard.

Wang Shijie gave a thumbs up, "Dad, you are still smart."

...

Seven days later, the Wang family transported the first batch of meat oil to Qingzhou, and the last ingredients for producing soap were also complete.

Although news from all aspects proved that the Wang family did not put on the trap, Xiao Ming was excited about the large amount of meat oil this time. For this reason, he specially asked the Equipment Department to build five huge iron pots and also selected the location for soap to be refined in the workshop area.

The production location of soap will be here in the future.

"Your Highness, how do you use this soap with oily smell?" Luluo followed Xiao Ming this time and insisted on seeing the production process of soap.

Since the concept of soap was proposed, the news about soap has slowly spread throughout the royal palace and in Qingzhou City.

Of course, women are most concerned about this kind of toiletries.

There were five large stoves in front of Xiao Ming. There were coal burning in the stove, and a large iron pot two meters wide was steaming.

Because it is winter, these meat oils have not rotted and deteriorated yet. The first step is to boil out the fat meat and the oil in the fat. After all, the barbarians will not directly extract the oil for him.

After the fat and oil in the fat comes out, the meat residue, skin and other things will be removed. Now this step has come.

"Hehe, the fragrance I asked you to prepare is not for nothing." Xiao Ming said at this time.

Luluo was stunned for a moment before she realized it and said shyly: "I thought Your Highness was used to make perfume."

This time, Xiao Ming did not avoid Wang Shijie, but asked him to come here in person. At this time, he saw Xiao Ming and Luluo flirting and couldn't help but envy, "Your Highness, you're so lucky."

Green ivy's face turned red, Xiao Ming glared at Wang Shijie. The boy said three words without leaving his business. He said: "This time I asked you to come here to let you supervise the use of meat oil. I have always been fair and just in doing business and will not take advantage of your Wang family."

This time the meat oil was provided by the Wang family, so it was not suitable for the Wang family to come. However, Xiao Ming was not afraid that the soap technique would be learned, because this soda ash is the key to making soap.

This time Xiao Ming came with soda ash directly, and Wang Shijie didn't know what this was used for.

The uncooled meat oil is orange-yellow and transparent, the color is the same as the modern soybean oil. When the first pot of pure meat oil came out, Xiao Ming asked someone to pour soda ash into it.

At this time, a chemical reaction suddenly occurred in the oil pan. After a while, the meat oil became sticky, like tofu brain. Then he asked someone to pour the essence into it and stir.

When the soap liquid in the oil pan was thick enough, he asked ten strong slaves to put the soap liquid into the prepared large square mold in an iron pan.
