The recovery price of one gram is 398.

One tael of gold is 37.3 grams.

The recoverable price of one tael of gold is 14845.4

I looked at the silver in the mall again, 5 yuan a gram!

The current gold-to-silver exchange ratio is about 1:8

This...

Looks like I've found some great bug.

Zhu Youzhen had an idea in his heart, gave up the exchange at the moment, and returned to the Qianqing Palace.

"Wang Banban, call Xu Yingyuan back."

"Yes, hooray."

After a while, Xu Yingyuan came back again.

"Have you given any holiday gifts to members?"

"Long live the return, the slave and maid have already been arranged."

"In the future, I will remember to give some gifts to members during the holidays, so that they can feel the warmth of the store. In addition, you go to two larger shops, and I plan to open a bank, which is called Global Bank. ”

Since there is such a loophole to exploit, it must be acted. Open a bank and exchange silver for gold, and you will have money.

He explained in detail the basic operation model of the bank and asked Xu Yingyuan to find a reliable person to take care of it.

sent Xu Yingyuan again, and received a report from the eunuch outside.

Song Yingxing of the Ming Royal Academy of Sciences asked to see him outside the palace.

Good fellow, I was looking for you, and here you are.

A moment later, Song Yingxing came in.

"Your Majesty, the minister has a happy event to announce to Your Majesty!"

"I already know, tell me, how did you find out the ratio of cement?" Zhu Youzhen said confidently.

"Yes, Your Majesty, that one was accidentally made by the minister." Song Yingxing hid the little pride in his heart well and said calmly.

Accidental? Cement is such an awesome and complicated thing, you accidentally got it out? You tech nerds love to pretend.

"Oh? Is it regular cement or slag cement? Or pozzolana cement? It can't be mixed cement, right? ”

Song Yingxing was stunned again.

What's that? Is there so much variety?

"It's Portland cement, right? How was it made? What kiln is clay fired in? Is it a lime kiln, an inverted flame kiln or a brick kiln? What is crushed and ground with what? Stone grinding or flat grinding? How is the powder sieved out after grinding? Is it a single-deck hand-cranked screen or a double-deck hand-cranked screen? What is the mix of the sieved flour together? ”

A series of questions made Song Yingxing stunned. He just read the simple production method from the book and experimented with it, why can't I understand what His Majesty said?

Zhu Youzhen looked at Song Yingxing, who was confused, and smiled with satisfaction.

As soon as you open your mouth, you know that you have to pretend to be forced, can people who engage in scientific research be proud? Keep your feet on the ground!

"Ministers, ministers are stupid. The minister just burned some of the bricks when he burned them, and then sifted them out with a stone mill and then mixed them. The yield is small and still needs improvement. ”

"I went back and ordered someone to send you a copy of the materials on making cement that I just mentioned, and you can study it. Cement is very useful, it can be used to build roads, build houses, and build city walls. You have to pay attention to it! ”

"Thank you, Your Majesty! The minister must pay attention to it. ”

"By the way, why are you here today?"

Song Yingxing suddenly woke up after listening to Zhu Youzhen's question. What am I here for? I'm here to report to work! I developed a textile machine that can spin sixteen threads at the same time! Shouldn't you be praised and rewarded by Your Majesty?

Zhu Youzhen's several questions struck Song Yingxing's little pride cleanly. Science is endless, and you still have to learn!

"Back to Your Majesty, the minister has researched a spinning machine that can spin sixteen silks at the same time!"

"Hmm. That's it? ”

That's it? My God, I studied day and night, without sleep or food. That's it?

However, when I thought that even the previous spinning machine was given by His Majesty, I was only improved on the basis of the original. Thinking about it like this, I don't feel how powerful I am, at least it's far worse than His Majesty.

Zhu Youzhen looked at Song Yingxing, who was choked by himself, and said with a smile:

"Wang Companion, reward Dean Song with a thousand taels of silver and ten pieces of cloth."

"Thank you, Your Majesty!"

After Song Yingxing left, Zhu Youzhen lay down on the chair. This is physically tired in the military academy, and mentally tired when I return to the Qianqing Palace.

Dinner is still eaten with Zhou Yufeng, because I will go back to the military academy later, today's dinner is a little earlier,

After dinner, Zhu Youzhen told Zhou Yufeng again to let her pay attention to her body, and then rode back to the military academy. By the time I arrived, there was still a quarter of an hour before the time of the incident, and most of the students had already returned.

戌時

Zhu Youzhen blew the whistle of the assembly on time!

"One shift counts."

"One, two, three..."

"Second shift counts."

"One, two, three, four..."

After reporting the number, Zhu Youzhen's face became gloomy, and there were not enough people.

"Who didn't arrive?!"

No one dared to speak.

Zhu Youzhen looked at it again, and the squad leaders of the two classes were not there, which made him angry.

"What about Zhu Kezhen and Wang Lai?"

The two of them are the squad leaders of the first and second shifts, and they actually took the lead in being late at this time!

A quarter of an hour passed, two quarters of an hour passed.

Zhu Youzhen's face became more and more ugly, and the students became more and more nervous as they stood there.

Finally, the news came.

Zhu Kezhen and several people were arrested by the Five Cities Soldiers and Horses Division for fighting in the restaurant.

Today's begging festival, Wang Laipin, who couldn't stay idle, proposed to go into the city for a walk, take a break, and relax his mood.

So Zhu Kezhen, Wang Laipin, Xu Yanqi, Zhang Zaigeng, and Liang Xingzhi rode into the city. Like a tired bird out of the cage, I was very happy.

A few people were shopping and playing in the city, and seeing that the time was not early, Zhu Kezhen proposed to hurry back to school after eating. So a few people found a big restaurant, opened a private room, ordered a few hard dishes, and ate happily.

Suddenly, Xu Yanqi's action of picking vegetables stopped, and frost was on his face that was smiling all year round.

Because he heard the conversation next door.

Seeing that his face was not right, Wang Laibin also stopped his movements and listened attentively.

"A group of reckless men are also worthy of the palace test? What's the use, governing the country still depends on us scholars. ”

"It's just that they're all simple-minded and well-developed limbs. At most, be a big soldier. Hahaha..."

"That's it, I think the saint is confused today, what kind of martial arts palace test are you doing, and those people are also worthy?"

"In my opinion, Your Majesty is not confused, but faint. I heard that I haven't been back to the palace recently, and I eat and live with that group of reckless men at any military school. Isn't this a faint thing? ”

Hearing this, Xu Yanqi couldn't hold back any longer. I slapped my chopsticks on the table and walked out.

Seeing this, Zhu Kezhen and the others also followed him and arrived at the door next door. Xu Yanqi kicked the door open, and pulled a few people who were talking inside. Seeing this, Zhu Kezhen and the others followed suit, each of them chose a target, and punched to the flesh. Several people in the house were caught off guard and were beaten by them.

In other words, even if you are on guard, you can't take precautions, with the level of Zhu Kezhen and a few people, you can beat them into dogs if you pull them out.

In a few moments, everyone fell to the ground and groaned.

The food and drinks on the table were scattered all over the floor, and the room was in shambles.

The shopkeeper heard the movement and ran up, and when he saw this scene, he immediately sent someone to notify the Five Cities Soldiers and Horses.
