This scene amazed the onlookers in the audience.

It seems that this fairy is drunk, it is really powerful!

The first time I went up a hundred people, not one of them could drink a pound and a half.

Not to mention that the whole five catties of immortals are drunk!

And through the first competition, the name of the fairy drunk is even more famous!

After the first event, the staff on the stage cleaned up the scene, rearranged it, and then the second competition continued.

Of course, there will naturally be other people to host the later activities, so there is no need for Li Su to continue to stay here.

……

Walking on the streets of Yizhou, you can find that because of this event, there are a lot more tourists than usual.

The streets are already crowded.

This time, the event was quite successful.

As long as this time the activity of looking for wine fairies, there are not too many wine fairies that can drink five catties, or even none, then the effect will be better.

If you can't find any of them, you can even raise the bounty by 100,000 dollars.

Well, 65 degrees of high wine, drink five catties in half an hour, I'm afraid it's really hard to find.

Even in the future generations, I'm afraid I won't be able to find a few.

After this search for the wine fairy, a winter fishing can be held before the year.

Well, strive to make Yizhou City, which has regular activities throughout the year, can attract a large number of tourists.

In this way, Yizhou City will be prosperous and powerful because of tourism.

Next, there was nothing to do, and Li Su couldn't help but go back to the Jiedu Embassy.

After going back, I happened to meet the student Di Renjie.

Seeing Di Renjie, Li Su couldn't help but feel a little ashamed.

Since accepting Di Renjie as an apprentice, Li Su has taken out some books for him to study on his own, and basically hasn't bothered much about his affairs.

It's really incompetent to be a master of your own.

Seeing Li Su, Di Renjie respectfully saluted Li Su.

Li Su nodded, and then asked Di Renjie, "Renjie, where are you reading now?" ”

Di Renjie couldn't help but reply: "Master, my disciple has been studying arithmetic recently, and he has just learned calculus. Yesterday, I compared with Master Wang Xiaotong in arithmetic, and the disciple was slightly better. ”

Wang Xiaotong is a genius of Datang's arithmetic, and he has taken a step forward in Datang's arithmetic on the basis of his predecessors.

Now he is in contact with new arithmetic and serves as an arithmetic teacher at Yizhou University.

And this kid, how long has he been in contact with arithmetic?

Actually learned calculus? And in the competition, he actually defeated Wang Xiaotong?

Well, well, in fact, Wang Xiaotong's contact with new arithmetic was more than a year earlier than Di Renjie.

But Wang Xiaotong was originally a genius in arithmetic!

Looking like this, Di Renjie, this little guy, is really amazing!

Li Su saw that Di Renjie had arrogance on his face, as if he was waiting for his praise, Li Su couldn't help frowning slightly.

To do learning, we must guard against arrogance and rashness, and the feeling of pride and complacency is unacceptable.

Of course, the most important thing is that Li Su is still afraid that this kid will propose to compare with himself in arithmetic.

Before the crossing, Li Su had gone to college, so he naturally studied calculus.

It's just that I didn't use it for a long time, and most of the good writing knowledge I learned when I was in college was returned to the teacher.

If he competes with Di Renjie, Li Su really has no certainty of victory.

Of course, if Li Yu has the ability to systematically, he will naturally win.

But if you compete with your disciples, you need to use system capabilities, so you can't help but lose the price, right?

No, you have to suppress this kid's arrogance and let him know how powerful the master is!

Thinking of this, Li Su couldn't help but say to Di Renjie: "Renjie, you are good at learning, and you will be tested on your debut questions as a teacher to see how well you have mastered your knowledge." ”

Hearing Li Su's words, Di Renjie's face suddenly showed a look of eagerness to try, and he said excitedly: "Master, please ask the question." ”

Li Su smiled slightly, led Di Renjie to the kitchen, and then took out a water scoop from the kitchen water tank, and said to Di Renjie: "Renjie, the topic of the teacher is, you calculate the volume of this water scoop." ”

Taking the water scoop from Li Yu's hand, Di Renjie couldn't help frowning tightly.

It's a very difficult question.

Di Renjie has learned the volume calculation method of the spherical container, and the volume calculation method of the cylindrical cone has also been learned.

But this water scoop, that is, the gourd sawing through it, is not a regular cylinder or cone at all.

This is easy, how can I ask for it?

But since the teacher gave himself this problem, he must be able to calculate it.

Or, as Master Wang Xiaotong said, mathematics should not just stay in books, but should be applied to real life.

Since there is a water scoop in life, there should be a way to find the volume of the water scoop.

But this scoop is not a regular ball or cylinder, how to solve it?

Perhaps, we can change the shape a bit?

Holding the water scoop, Di Renjie couldn't help but fall into hard meditation.

Seeing this scene, Li couldn't help but smile slightly.

This question can probably stump him.

Don't rush, just wait two days and see how he solves it.

……

At this moment, Wu Meiniang came to ask for a meeting.

After seeing Wu Meiniang, Li Yu found that after not seeing her for a while, Wu Meiniang became more and more tall and charming.

After the two talked for a while, Wu Meiniang got down to business: "Your Highness, now the business of our Chinese Commercial Bank is getting bigger and bigger, and the money we handle is getting bigger and bigger. Some large transactions require the money of several truckloads, which is really inconvenient. I wonder if Your Highness has a good solution? ”

Hearing Wu Meiniang's question, Li Su couldn't help but nodded.

This problem finally arises.

This problem, in the early Tang Dynasty, has just emerged.

It will become more and more intense with the continuous prosperity and prosperity of Datang.

This problem can be divided into two aspects.

First, the purchasing power of copper coins is too low, and once there is a large transaction, it will become extremely inconvenient to pay.

The other is that because of the limited mining capacity in this era, there is only so much copper that can be mined every year.

There are only so many copper coins that can be printed every year, but the GDP will rise faster than you can print copper coins.

At this time, there will be a phenomenon of insufficient money.

In the original historical trajectory, the Tang Dynasty faced this danger.

And now, this kind of problem has begun to emerge.

After thinking about it, Li Su couldn't help but say to Wu Meiniang: "This problem is actually easy to solve, we can open a money bank." You can have people deposit money into the bank, and then we will give them a receipt. With this receipt, you can withdraw cash from all our banks. You can also shop directly with your receipt. ”
