The Princess of the Substitute Bride Strikes Back

After receiving the coal sent by the county magistrate, Fu Yunxi and Mu Yibai started their experiment. They prepared to wash the coal by the well in the yard.

"Xi'er, please sit here, I will take care of it." Mu Yibai asked Mu Da to move a chair from the room and place it aside, for fear that Fu Yunxi would be stained by the coal.

"Okay, fill a large bucket with water first, and then pour this in." Fu Yunxi took out a bottle of polyacrylamide from the space and handed it to Mu Yibai. Mu Yibai did not ask any more questions and poured it in according to the proportion Fu Yunxi said.

"This powder can help us effectively remove impurities from the coal, including some substances that are invisible to the naked eye." Fu Yunxi watched Mu Yibai operate and explained to him at the same time.

In this era, polyacrylamide does not exist, but in the world of the previous life, polyacrylamide was widely used in many occasions, such as lubricant, stabilizer, and can also treat tap water.

This item is very useful for her scientific research, so she stockpiled some in her villa in the space. She never thought that it would be used for coal washing now. What a trick of fate!

"Is this medicinal powder so miraculous?" Mu Yibai couldn't help but sigh that the world is so big and full of wonders. This packet of medicinal powder can actually remove impurities that are invisible to the naked eye.

"Well, but the amount of this powder is limited. We must negotiate terms with the county magistrate tomorrow, otherwise we will suffer a loss!"

The coal washing technology is something people have gradually discovered after a long period of research. In the era when she lived, the coal washing technology could support the development of a factory, and those equipment could not be replicated in this era.

She can only extract the principles and try her best to improve the purity of coal, reduce environmental pollution and reduce resource waste.

"The county magistrate will definitely agree. How much profit do you plan to discuss with him?"

Mu Yibai looked at Fu Yunxi's quirky appearance and found it very interesting. No one could suffer a loss, but she couldn't!

His Xier has always been the kindest and the most dazzling person!

"My dear, how much profit do you think is appropriate? This is the first time we are cooperating with the government. If we ask for too much, others may envy us. If we ask for too little, we may feel disadvantaged."

Speaking of this, Fu Yunxi was worried about it. This business of cooperation with the government was indeed very reliable.

But cooperation also requires sincerity, otherwise it will be difficult to convince the public.

"Ma'am, is this powder unique?"

Mu Yibai did not answer directly, but first asked whether the powder used for coal washing could be developed by ordinary people.

He believed that this medicine powder was extremely important because the coal in the barrel was becoming purer at a speed visible to the naked eye, and many impurities were floating in the water, and there must be impurities of other colors under the water.

"Of course not. This medicine powder is an object in the space. There is not much of it. We can only take out some every day."

"This medicine powder is a high-purity compound, which certainly cannot be purified in this era. The substitute of medicine powder can be slowly researched, but the amount stored in the space should be enough for the time being, and it can be automatically replenished every day. This can also be regarded as her sincerity in investing in technology and providing key materials."

"Then I think Madam can raise the standard to 50% of the net profit. If it is just a simple technology investment, then the county magistrate may be more inclined to buy out your technology. But now the nature has changed. If we want to realize the technology, we need the key medicine powder you provide, so we must not be at a disadvantage."

Mu Yibai was right. The technology could be bought out, but the county magistrate did not have such critical raw materials.

In the future, Fu Yunxi will be able to update and improve this technology, which is her advantage as a partner.

"I think so too. I didn't discuss this with the county magistrate today mainly because the finished coal product has not yet been produced. Judging from the current results, it is still quite good, so 50% is more reasonable."

After listening to Mu Yibai's words, Fu Yunxi had an idea in mind. She asked him to dehydrate the washed coal and it would become a finished product.

"In fact, if the technology is mature, these coals can be compressed into a fixed shape, but unfortunately we can't achieve it at present."

Fu Yunxi looked at the coal pieces of different sizes after being dehydrated and said to Mu Yibai.

"The coal washing technology proposed by Xier is beyond the reach of others. The processed coal is classified according to size, and it looks very neat."

The silver charcoal that Mu Yibai had used before was also a finished product of uniform size mined by workers. After all, the things used by the royal family not only have to be of high quality, but also have to be beautiful!

"Well, that's fine too. It's just for heating anyway."

What Fu Yunxi did not say was that in her era, there was not only coal, but also honeycomb coal and liquid coal.

These different forms have different uses and advantages, but for this era, coal is more than sufficient.

"Let me try to light it."

"it is good!"

Fu Yunxi stared at Mu Yibai's serious and focused expression. Even though he was fiddling with coal, there was not a speck of dust on his body. His figure was slender, and his clothes fluttered with his movements. One had to admit that he was so beautiful that it was pleasing to the eye!

"Madam, what do you think of this effect?"

Mu Yibai's words made Fu Yunxi regain her composure. She instantly looked embarrassed. Why had she been staring at him so intently just now?

"Ah! This one looks good."

Fu Yunxi didn't know whether Mu Yibai had noticed her previous distraction, and responded a little awkwardly.

"Well, the effect is acceptable, but it looks a little ugly, far inferior to my husband's handsome face."

Mu Yibai looked at Fu Yunxi with a smile, the corners of his mouth slightly raised.

"Why are you competing with coal? Everyone is always better looking than coal!"

Fu Yunxi knew that Mu Yibai had seen through her embarrassment just now, and she couldn't help feeling a little annoyed. She simply ignored him and focused her attention on the burning charcoal.

"Madam is so lovely."

Mu Yibai didn't expect Fu Yunxi to be so unable to resist teasing, so he hurried forward to coax her.

"Humph!"

Fu Yunxi looked at the coal carefully and found that the purified coal could be quickly burned by the ignition agent, and there was no choking smoke. It seemed that the experiment had been successful!

"The burning condition is no less than that of silver charcoal."

Mu Yibai was also attracted by the coal and felt that the craftsmanship was truly extraordinary.

"Indeed, coal of this purity is sufficient. I think our experiment is a success. For your hard work, I will forgive you!"

Fu Yunxi was overjoyed. The coal washing method recorded in the book was indeed correct. Not only did the purity increase to a higher level, but the combustion effect was also very different.

"It's all because of your wisdom, otherwise who could have such ability?"

Mu Yibai kept saying nice things to coax Fu Yunxi, so that she wouldn't be upset anymore!
