Li Lizhen: "What do you know?" ”

"I just knew I needed an accountant."

“……”

Li Zhi pulled the corner of Li Li's clothes and asked, "Sister Huang, what is accounting." ”

Li Lizhi also looked at Li Zheng, "What is accounting?" ”

"In the eyes of accountants, money is just numbers, they are the ones who really don't take money seriously, they are professionals."

Li Lizhi asked again: "Li Zheng, do you only have money in your eyes?" ”

"No, I still have poetry and distance in my eyes."

"I don't believe it!"

"Well, I'll tell you, until I can earn enough money for retirement, my only hobby may be to make money."

"Humph! And so it was. ”

Li Zhi ate ice cream one bite after another with a small wooden spoon.

Although I don't know what Li Zheng and his imperial sister are talking about.

But he knew that anything he didn't understand must be very powerful.

The old master Kong Yingda, who taught himself, was very powerful.

I couldn't understand what Old Master Kong Yingda was talking about in class.

It's best to pretend to understand at times like this.

Because they won't be trained.

Li Lizhi left with Li Zhi in frustration, in fact, she wanted to talk to Li Zheng for a while.

It's just that I'm afraid that my younger brother will be damaged by Li Zheng.

Li Zhi is still young and ignorant of the world.

After Li Lizhi left with Li Zhi.

Li Tai also returned to Jingyang tiredly.

With the hot water that Li Zheng was going to take a bath, Li Tai drank hot tea and said, "But it's too busy for me." ”

"Nothing serious." Li Zheng asked while boiling tea eggs.

Di Zhixon brought a lot of tea, which is enough to eat until next year.

Li Tai looked tired, "Thanks to your reminder, fortunately, there was no big disaster, in fact, I understand the truth, but it is not as comprehensive as you think, this heavy snow is no different from heavy rain, when Cen text compiled the gazetteer, it was recorded in the classics, and the foothills of Chang'an collapsed." ”

Arrogance is the greatest enemy of mankind, and happiness is the greatest hidden danger to tranquility.

"Confucius said: Born in sorrow, die in peace." Li Zheng sighed.

Li Tai peeled the eggshell of the tea egg and said lazily: "That was said by Mencius and his old man, not Confucius." ”

"Really?" Li Zheng touched his nose with some embarrassment.

Li Daxiong returned home, the three of them sat down and had dinner, and Li Tai fell asleep.

Li Zheng also learned what happened in Long Shouyuan from the news sent by Li Yifu.

Longshouyuan is actually fine, but the most serious place is still Bishan.

Thousands of houses were flooded by the drift of the mountain.

It has a certain relationship with geology.

Li Zheng remembers that when he was a child, he would often be on the mountain road, because of rolling stones and landslides.

Once a landslide occurs, it takes a long time to rebuild the road.

Of course, there is also a human factor.

For example, there are some people who claim to be a captain of Cao Jun.

In order to make a fortune, it is also related to the fact that they carry shovels and dig everywhere in the mountains of the Qinling Mountains.

Eighty percent of the mountains are almost hollow.

There is also a large number of forests to cultivate and build mausoleums.

Too much vegetation has been removed, which is a key cause of soil erosion.

In this age when eating is a top priority, who cares about protecting the environment.

As long as you can eat enough food, as long as you can grow food, even the woods and mountains are the enemies of the people.

The snoring at home was thunderous, and Li Daxiong and Li Tai snored one after another.

Li Zheng lost sleep again.

On the second day, the weather was finally clear.

In the warm sun, Li was lying on the chaise longue he had made, intending to catch up on his sleep in the warm sun.

Li Tai returned to Chang'an and hadn't come to the court for a long time.

Li Chengqian's face is also very bad, maybe he hasn't rested since he was busy yesterday.

What did the early dynasty say, Li Tai didn't listen to the court's discussion at all.

The tired body stood weakly, and at the moment he wanted to go back to his mansion and sleep again.

After the next dynasty, Li Tai returned to his mansion.

Li Chengqian also returned to the East Palace.

Cen Wenwen sat in the Literature Museum, looking at the new map sent by Li Tai.

There is no detailed depiction on these maps.

Rather, there are only a few lines.

If you look at these lines, you can see the trend of the mountains and rivers and the height of the terrain.

Cen Wenwen asked the little official beside him suspiciously, "His Royal Highness King Wei is judging the location of the flash flood by looking at this map?" ”

The officer replied, "Indeed. ”

Taking out another booklet, the little official continued: "This is a diagram made by His Royal Highness the King of Wei when he looked at the terrain. ”

Cen Wenwen took the illustrations and looked at the maps, which were full of lines.

Mountains and rivers were not drawn at all.

However, with the diagram, it does seem to be clear at a glance.

The meaning of those annotations is understood.

The more Cen Wenwen looked at it, the more curious he became, "Where did His Royal Highness King Wei get these pictures?" ”

The little official said with a smile: "Coincidentally, these pictures were taken from Jingyang, and it is said that they were the after-school homework assigned by Li Zheng to the children at that time. ”

Not to mention what the homework is after class, Cen Wenwen looked at the map full of contour lines and said in a low voice: "This kind of map is very useful for marching and fighting." ”

"I'm going to see Your Majesty."

Cen Wenwen's stack of drawings came to the palace, and after the palace attendants reported it, they entered the Liangyi Palace.

"Your Majesty!" Cen Wenwen held the drawings and saluted.

Li Shimin Xinglan Shan ate tea eggs, and after hearing that there was an extra food called tea eggs in Li Chengqian's palace, it naturally became a dish in the imperial dining room.

And this dish is extremely simple to make, and it tastes very good.

Cen Wenwen said again: "Your Majesty, the minister has a military weapon to offer. ”

"Militaristic weapons?"

Cen Wenwen took the drawings and spread them out in front of Li Shimin's desk, "Your Majesty, please take a look." ”

After eating the tea eggs and taking another sip of wolfberry bubbles, Li Shimin looked at the drawings full of lines.

“……”

Looking up at Cen Wenwen again, Li Shimin asked, "You just show me this?" A militaristic weapon? ”

"Your Majesty, the terrain has always been particularly important in marching and fighting, and whoever grasps the terrain first can grasp the opportunity."

"Of course I understand what you're saying." Li Shimin thought about the new year, and I also had great achievements.

Li Shimin looked at these unexplained maps, "Then you talk to me, how can drawing these lines give my Tang army the upper hand?" ”

"Your Majesty, in fact, this is a map, a topographic map to be exact."

"Are you kidding?"

Cen Wenwen explained to Li Shimin for a long time how to draw this topographic map, and through the density of the lines and the curvature of the lines, you can roughly know the outline of the mountains and the terrain.

After hearing this, Li Shimin became more and more interested, and when he was fighting in the past, he suffered a lot of losses because the map was unknown.

The quality of the terrain often determines the outcome of a major battle.

The map I have been working with for a long time is at most to draw a tree as a forest and a triangle as a hill.
