Bi Zhong bowed, "Thank you, Your Royal Highness the Prince, as long as my things are still there, I can continue to study them after I am released from prison, so that I will be satisfied." ”

Chen Mu smiled and nodded, and did not say any more about this question. Instead, he asked someone to pack up Bi Zhong's things, and then took Bi Zhong with him.

In this world, as long as Chen Mu knows the importance of mercury.

First, it can be used to purify gold.

Now the gold of Great Xia is very coarse, yellow with black, and it is ugly. And the gold purified with mercury will become golden and look good.

This method is very simple, and Chen Mu knows it.

And mercury has many other functions, which Chen Mu is not clear about, and the current level of science and technology cannot be used.

This will be very useful in the future.

A few days later, the government found the man who smuggled the "silver mine" and also found the mercury mine. Chen Mu immediately ordered someone to control the place, and then opened a state-owned mine.

Chen Mu also opened a state-run alchemy field in the northeast region, and in the future, the gold paid by the Rakshasa Kingdom would come here first, and then purify it with mercury, and then transport the pure gold back to the national capital.

Mercury alchemy is very dangerous, Chen Mu handed over this job to the slaves of the Stick Country, this batch of people is dead, and then catch a batch of them in the Stick Country.

In the national capital, there is also a state-run jewelry workshop, which processes pure gold into a variety of beautiful jewelry.

Chen Mu set a series of regulations to make gold jewelry a new luxury item in Great Xia.

The gold jewelry grade system includes: what kind of emperor can wear, what kind of prince can wear, officials of each rank, families who have achieved rankings in the imperial examination, soldiers who have made military achievements, etc., are very carefully divided.

As a result, gold jewelry has become a symbol of dignity, and everyone has gone to the state-run jewelry workshop to buy and book.

The Great Xia treasury has another large amount of income.

This is not entirely speculation, as gold is indeed a general equivalent, which can be exchanged for silver and copper coins.

This is also equivalent to a kind of financial investment, a kind of savings, which is equivalent to hanging money on one's body.

After doing these things, Chen Mu took people to a mansion to see Bizhong's scientific research results.

When Bi Zhong saw Chen Mu coming, he immediately knelt down respectfully and kowtowed.

"Student Bizhong, meet His Royal Highness the Prince!"

Chen Mu waved his hand, "Excuse me, how is your research going?" ”

Bi Zhong immediately became frowning, "Your Royal Highness the Prince, I have discovered a new way to preserve mercury, which used to be sealed with mud, and the effect was very poor. But I later discovered that as long as you put oil and water on top of the mercury, it doesn't evaporate. ”

Bi Zhong showed Chen Mu the latest preservation device, and Chen Mu was very happy.

"Good! This makes it easy to ship to the Northeast, which is much easier than shipping gold! Be sure to give you credit! ”

Chen Mu was right, gold is very heavy, and it may be stolen, and it is very troublesome to transport. Mercury, on the other hand, is much more convenient, not only is it small in size and light in weight, but it is useless for others to steal it.

Bi Zhong waved his hand again and again, "His Royal Highness the Crown Prince can give me this opportunity, I am already grateful, how dare I ask for any reward?" ”

Chen Mu: "Eh, this is the rule of the School of Engineering, and you can't make an exception, otherwise it will affect the enthusiasm of others." You will be rewarded for your hard research in the future, and you will have to communicate more with other classmates to make progress together. ”

Bi Zhong thanked him again, and Chen Mu left here and went to inspect other places.

Chen Mu said that Bi Zhong was locked up, but it was not a prison, but a newly established engineering college.

The students here no longer look at the knowledge of books, but look at whether they have the hands-on ability to study the technology that has not yet been discovered in Great Xia.

Including carpenters, potters, blacksmiths, etc., can study new technologies here, the imperial court provides food and shelter for pocket money, and there are also heavy rewards for research results.

Chen Mu came to inspect when he had time and gave some tips.

In addition, there are various academies such as the College of Agriculture and the School of Medicine, which are all in this model.

When discovering mercury, Chen Mu deeply felt that a person's memory is limited, and Chen Mu's skills alone are still too little.

In Chen Mu's previous life, there was no shortage of skilled craftsmen in ancient times, and many ancient techniques were difficult to replicate in modern times.

Chen Mu is only good at history, but for many scientific products, he only knows a rough, specific scientific principle, which requires a person like Bi Zhong to conduct long-term research to figure it out.

Chen Mu believes that as long as Daxia continues to run these academies, sooner or later there will be steam engines and generators, which create the products of an era.

The time soon came to autumn, and Chen Mu had been in this world for two years.

On this day, a big event happened.

Chen Xingtian called Chen Mu to the palace and asked the messenger to tell Chen Mu about the disaster.

It turned out that the great river in the south had flooded, including most of the Dongyuan, the northern part of the southern Xinjiang region, the southern part of the Central Plains region, and the entire coast of the great river.

In addition, many houses were destroyed by the floods, and countless people were killed and injured.

After the messenger finished speaking, Chen Xingtian asked, "Mu'er, what do you think about this?" ”

Now Chen Xingtian is already every time there is a major event, he must ask Chen Mu, if it weren't for Chen Mu always leading troops to fight, he would have given up the throne to him.

Chen Mu thought for a moment, "I think it should be divided into three steps." ”

"First, the surrounding counties were ordered to open warehouses to release grain, and to provide food and clothing to the victims, all of which were reimbursed by the state treasury."

Chen Xingtian nodded, the government originally had the responsibility of disaster relief, but with this decree, the counties had no worries.

"Second, ask people to go to the northeast region to allocate rice to help the victims."

Chen Xingtian nodded, the northeast region has not been affected, and now the autumn harvest has begun, which should be able to supplement the needs of the disaster area.

"Third, I will personally supervise the flood fighting, and I will bring 30,000 soldiers, please ask my father for permission."

Chen Xingtian was stunned.

This one is very special.

It stands to reason that the army is used to fight wars, so why do you bring so many soldiers for disaster relief?

"Is the shepherd worried about a rebellion from the victims?"

Chen Mu shook his head, "I took these soldiers to work." ”

"Judging from the news just now, it is already difficult for people in the affected areas to eat, and the government is also busy providing relief to the victims and maintaining order. Who will build the dam? ”

Chen Xingtian suddenly realized that he really hadn't thought that the army could be used like this.

Chen Mu naturally thought of it, because in his previous life, this was a very common thing.

Chen Xingtian agreed one by one and sent envoys to various places to deliver orders.

Chen Mu also ordered 30,000 troops and set off lightly.
