Wenyi immediately took out the quadratic linear equation to suppress this little fat man who knew nothing about the world. When Li Tai saw the new knowledge, he was like a cat smelling a fishy smell. In the blink of an eye, he looked like a good baby and almost squatted on the ground wagging his tail.

Wenyi also liked this talented little fat man very much, so he summoned his eldest disciple with a letter.

Let Shitou be responsible for teaching Li Chengqian and Li Ke, and teach Li Tai himself.

After two months of observation, it was found that the third brother had a somewhat arrogant personality, which was probably a common problem among aristocratic children. Wenyi carefully searched Xiaomi’s database, selected some information from it and compiled it into an ideological and moral teaching material, and began to study these three areas.

The rough jade is carefully carved.

The effect is still a little bit, but these problems are all cultivated from childhood. It is difficult to change. Wenyi thought hard for several days and finally decided to do something big! He used the excuse that his mother was around and he couldn't use the real method.

He used various methods to discipline the three brothers and deceived the eldest grandson and Concubine Yang back to Chang'an.

Princess Pingyang lives in a villa in a small town. She occasionally goes for a walk in the town and only asks about her studies.

Hua Mulan came here to raise her baby, and Wenyi himself hired a dozen midwives from the Xiao Mansion to take care of Hua Mulan if he had something to do.

Shu'er could just find an excuse and get it done.

Everything was ready. Wen Yi called the three brothers up early that morning, gave each of them a set of coarse cotton-padded clothes, and each of them a small baggage. He also dressed up in the same way.

The three brothers were a little confused. After they exchanged glances, Li Chengqian asked: "Master, what are we going to do?"

Wenyi Dao: "As the saying goes, 'It is better to travel thousands of miles than to read thousands of books.' I will take you to travel around the beautiful rivers and mountains of the Tang Dynasty."

The three brothers believed it and immediately changed their clothes happily and threw the small bundle to their attendants.

Wenyi said at this time: "You can take the baggage by yourself, there are only four of us going out this time.

There will be a team of Xuanjia troops protecting us secretly, but all problems we encounter need to be solved by ourselves.

That team of guards only listens to my orders, you can't command them."

The three brothers didn't take it seriously. The art classes were different from those of the dull old men. They basically didn't have a specific style and they had long been used to it.

The four of them chatted and laughed and wandered out of Shanghai County. Li Ke seemed to realize something and asked: "Master, where are we going?"

Wenyi smiled and said: "Go to Chang'an."

Li Ke's heart skipped a beat and he quickly asked: "How to get there?"

Literary Art: "Let's just go here.

How else do you want to go?"

At this time, Li Chengqian also came to his senses: "Master, why don't we just walk over like this?

We can go back by car, it’s so far away from Chang’an!”

Wenyi shook his head and said: "I told you that we are traveling, how can we take a carriage?

One more thing I want to remind you is that each of you has two pieces of money in your bag. This is your money for the journey from here to Chang'an. How you spend it is your business, but if you spend it before you get to Chang'an, your assessment will not be considered.

failed.

And after the money is spent, I will provide relief materials: half a steamed bun for a meal, and enough water pipes to ensure that you will not starve to death."

It was only then that the three brothers realized that something was not good! Li Tai asked: "Master, which way should we take to Chang'an?"

Can I ask for help if I meet an acquaintance on the road?”

Wenyi said: "I only know that Chang'an is in the west. You can figure it out for yourself how to go. Of course, I will change the route at will to ensure that we will not be too relaxed."

You can seek appropriate help on the road, and the limit is determined by me.

Okay, you three can discuss the next step."

The three brothers looked at each other, feeling not only fear of the journey but also an inexplicable excitement.

The three little guys murmured for a while, and finally adopted Li Ke's suggestion. They first went to Hangzhou to ask Xiao Mansion for a detailed map, and then discussed the specific route.

In ancient times, the only way to travel far was by car or on foot. Now the four of us choose to hike. On the first day, we were very excited and walked very fast. We walked 50 miles in one day, which was already the limit for a five or six-year-old child.

Already.

Although the four of them are on the official road now, Shanghai County is a newly built county and there are not many vendors on the official road.

A few people had to find a creek to prepare for camping.

The tents and other arts and crafts are still prepared. After all, these people are still children and cannot be too demanding.

Wenyi sat on the fire and skillfully roasted the pheasant that Li Ke had caught. The three little guys sat in a row opposite Wenyi.

Wenyi said: "First tell me how you feel today."

Li Chengqian was the first to say: "Master, I just feel that walking is so hard today. Moreover, I have observed that there are basically no people after leaving Shanghai County. The people who occasionally pass by on the official road are traders going to Shanghai County."

Wenyi nodded and said: "Do you know how many people there are in Datang now?"

Li Chengqian thought for a while and said: "My husband said before that there seem to be less than three million households in the Tang Dynasty."

Wen Yi added: "Do you know how big the territory of the Tang Dynasty was?"

Several people shook their heads, and Wenyi said: "At present, the Tang Dynasty has a land of five million square kilometers, but the population is less than three million households, and most of the population is concentrated in the north.

So it is normal to not see many people, which means that our population in Datang is too small and we are in urgent need of recuperation."

The three brothers nodded silently, and Li Tai said at this time: "Master, today I tried walking on the dirt road and on the cement road. I found that walking on the dirt road is much more tiring than walking on the cement road. This is why you insist on paving the road with cement."

The reason?"

Wenyi smiled and said: "You have observed very carefully. After the cement is formed, it is flat and hard. Compared with the soft dirt road, it has great advantages. It has low friction and is rainproof. The biggest disadvantage of the dirt road is that it is muddy after raining.

The carriages and horses could hardly move.

In my mind, this kind of cement road will be promoted throughout the Tang Dynasty in the future. This will not only make it convenient for people to travel, but also make traveling faster on the cement road if troops need to be mobilized.

Highways can be said to be the blood of the country, and only smooth roads can make the country run more efficiently."

Li Ke said: "Master, I feel that these two taels of money are very heavy, so I thought it would be great if I could exchange these two taels of money into silver. Two taels of silver would be much more convenient."

Wenyi said happily: "This is a big topic. Today's copper coins, cloth, silk, silver, and gold can all be used as currency, but they are extremely inconvenient to use.

Think about whether there is any way to make it more efficient and convenient.

If you can do it, you will definitely leave your name in history!"

Li Ke's eyes widened and he asked anxiously: "Master, do you have a plan?

Can you tell my disciples?"

Wenyi shook his head and said: "I do have a complete currency system, but I can't tell you yet. You have to figure it out yourself. You are still young. I will tell you when you have learned all the basic knowledge."
