After speaking, Cheng Yanjin picked up another chili pepper and ate it in his mouth.

Chili peppers were introduced to China in the late Ming Dynasty.

Chili peppers are a good thing to ward off cold and sweat, and they are also an indispensable ingredient for making delicious dishes.

Cheng Yanjin grabbed a handful of chili peppers and ate them one bite after another.

Li Zheng unexpectedly discovered that Cheng Yanjin could eat this thing as a snack.

It's just horrible.

"General Cheng, this thing is on fire if you eat too much." Li Zheng added.

"Out of the way." Cheng Yanjin said nonchalantly while eating chili peppers.

On the second day, Da Niu returned with the children of the village, and the topographical map of Chang'an had been drawn.

A huge scroll spreads out with dense lines drawn on it.

A large group of generals looked numb when they saw it, it turned out that the terrain of Chang'an was so complicated.

Li Zheng said to them: "The generals just need to draw it like that." ”

The generals of the five big and three thick were holding the brush in their hands and didn't know how to start.

Cheng Yanjin handed over his painting scroll to another general and asked him to paint it on his behalf.

It's good, in addition to copying homework, the generals have reached the level of writing homework on their behalf.

The progress is really great, and the generals are really bad students.

Li Zheng shook his head and sighed.

"If you can't do it earlier, why bother with such fanfare." Cheng Yanjin lay comfortably on the grass.

"It's good that General Cheng is happy." Li Zheng echoed.

The homework left by Li Shimin is not too difficult, the main thing is to waste time, in fact, the terrain of Chang'an is very flat, located in the plain, if you really say that the terrain is complicated, you have to go to see the Qinling Mountains.

It's time-consuming to draw, and you need to roughly measure the area, and you can't just fool around.

Even Li Shimin can't see that the ministers in the court are all rich and rich.

Contour topographic maps are complex to draw, but topographic maps are not very difficult to understand.

Cheng Yanjin said in a low voice: "Li Zheng, you are sharp at a young age, and you have offended a lot of people. ”

"I know, so I've wanted to train an undercover agent lately."

"Oh? What undercover agent? ”

Li Zheng whispered to Cheng Yanjin: "Once upon a time, there was a person who, in order to deal with his own mortal enemy, went away to learn skills, and then used the tricks he learned to deceive his enemies into bankruptcy. ”

Cheng Yanjin asked in a low voice: "Is there such a number one person?" ”

"Not now, but there may be [] later." Li Zheng nodded and said.

Li Shimin finally received the generals' homework after class.

Looking at the topographic maps, Li Shimin nodded, a little pertinent, but also a little skeptical.

Not necessarily all the generals in the DPRK and China have learned, and some of them must have done tricks.

Of course, Li Shimin didn't want to ask openly, just know it in his heart.

Especially Cheng Biting Jin.

Li Shimin said to Wang Ding: "If the decree goes down, Cheng will be fined for three years." ”

"Your Majesty, it's been ten years since General Cheng was fined......"

Cheng Yanjin returned to his home and was a little stunned when he learned that he had been fined for another three years.

Where did I provoke Your Majesty?

Obviously, I made my homework.

also caught those fine works lurking in Jingyang.

It stands to reason that it should be rewarded, but in the end, he was fined for three years.

In Chang'an, many people are talking about Li Zheng's road construction.

Li is the new magnate in Chang'an, and this magnate is a little eccentric.

It is not like other powerful people who enjoy a life of abundance.

Instead, they reclaimed land and built houses.

3,000 houses were built in Jingyang.

A lot of Li Zheng's money was spent on this.

There is a lot of talk in the market, Li Zheng is very rich, at least many people think that the entire Chang'an wants to say that Li Zheng's ability to accumulate wealth is the second, and no one dares to say that he is the first.

Just a few bottles of perfume made Li Zheng earn hundreds of thousands.

This twelve-year-old child's work of collecting money is outrageous and undaring.

Fame and money are in conflict.

A lot of times you have to spend money for fame, and if you want it, it's easy to lose it.

In the eyes of many powerful people in Chang'an, Li Zheng did this to spend money to buy fame, or to curry favor with Li Shimin.

"Fart!" Li Zheng said to Di Zhixon: "I built roads to make money. ”

Dickinson nodded, "I also know you're not a person who cares about fame. ”

"Of course you can make money, accounting is indeed an addition, but there is also multiplication and open squared, compared to addition, multiplication is not more difficult, if you learn multiplication, your arithmetic will be raised to a higher level, this is the difference."

Although Di Zhixun couldn't understand Li Zheng's words, he still pretended to take a sip of tea with a deep face.

"I'll continue to build roads." Li Zheng's words were affirmative.

In the following days, Li Zheng recruited many people to work.

It's also more expensive.

Li Yifu was busy all day.

The cold in winter gradually receded, and the greenhouses in the greenhouse fields could finally be dismantled.

The sun is getting warmer and warmer, too.

Li Zheng is comfortably soaking in the sun, and the climate in Datang will be much better in the future.

Li Chunfeng hurriedly came to Jingyang, found Li Zheng next to the horse circle and said, "Li Zheng, save Daoist Yuan." ”

"What's wrong with Daoist Yuan?"

"It's not you." Li Chunfeng said sadly: "Daoist Yuan hasn't had a good meal for a long time. ”

"Daochang Li, you can't talk nonsense, Daochang Yuan and I have no grievances or hatred, why should I rely on my head."

"It's not up to you, Yuan Daochang is going crazy, he studies the stars all night, and he is sleepless day and night and is about to go crazy."

"Is there such a thing?"

"That's true." Li Chunfeng said nervously: "Li Zheng, I know that you have unpredictable abilities, but you can't die without help." ”

"Daoist Yuan is really going crazy?"

"It's almost like I'm crazy." Li Chunfeng said in a low voice: "Li Zheng, in the middle of the night, I saw Yuan Daochang looking at the night sky in a daze, not to mention how scary. ”

Li Chunfeng hurriedly said: "Li Zheng, I know that some skills are not passed on, you must know some mysteries in order to predict the snow disaster, even if it is a shaking, I also hope that you can rescue Yuan Daochang." ”

Li Zheng pondered and said, "You can help, but you owe me a favor." ”

"Great, as long as you're willing to help."

"And!" Li Zheng said to him: "Can Daoist Li come to teach the children in the village math in the future?" ”

"This ......"

Thinking of Yuan Tiangang's situation, Li Chunfeng was so anxious that he stomped his feet, "Okay! As long as you are willing to help Daoist Yuan, I will come to your Jingyang Academy to teach the children. ”

Li Zheng had a smile on his face: "I'm tired." ”

On the second day, Li Chunfeng came with Yuan Tiangang.

Yuan Tiangang came to Jingyang again, and asked in a trance: "Li Zheng, the old man has been thinking about it all winter and can't figure it out, how did you know about the snow disaster." ”

"Does it matter?" Li Zheng said leisurely.

"It's important." Yuan Tiangang nodded and said, "If you encounter this kind of thing in the future, you can take precautions in advance." ”

"Don't worry, the weather should be much better in the future."

"How do you know for sure?"

The next 100 years will be a very normal climate.

Nature will always be the most irresistible god in this world.

God is not happy, a drought is enough to make this still somewhat ignorant era full of corpses.

Of course, when the climate is good, there will be a good harvest of food, and the population will grow rapidly.

Therefore, in order to keep the natural environment from losing its temper, it is also important to protect the natural environment.

Li Zheng sat up and looked at the old Taoist priest and said, "Daoist Yuan, we are not all the way, my method is different from yours. ”

"Could it be that the county marquis has any other way? Poor Dao has lived for so many years, and he has seen a lot of strange people. ”

"Dare to ask the county marquis what method he uses to predict the weather."

Yuan Tiangang seemed to have broken the posture of the casserole to ask the end.

Li Zheng explained to Yuan Tiangang: "In fact, most of the climate in this world can be predicted, and my method is different from Yuan Daochang's astrology and celestial phenomena, and I use a method of cause and effect. ”

Li Zheng didn't want to tell this old Taoist priest that he had actually seen this unusual cold wave in a book on historical meteorology.

Always have to find a way to fool the past, Li Zheng nodded, "Hmm! It is the law of cause and effect. ”

"Cause and effect...... It turns out that the county marquis will still have such a clever method, and the most difficult thing in this world to calculate is cause and effect, and the poor Dao admires. ”

“……”

This guy really believed it, in fact, if you want to say that Xu Fu is a model, he fooled the first emperor into a daze.

Yuan Tiangang said again: "Dare to ask the county marquis, what caused this snow disaster this time?" ”

"I can tell you, you must not tell anyone."

"County marquis, please speak."

Li Zheng cleared his throat and said, "There is a guy named Edward, who is known as a meteorologist in the rivers and lakes. ”

"Meteorologists? Is there this among the hundred sons? ”

"You don't care if you have this or not, there is such a person anyway."

Flickering, it's a big deal, Li Zheng said: "That Edward said a very interesting point, a butterfly in the north instigated a few wings, and half a month later a hurricane can form in the south. ”

"Hurricanes?"

"It's a gale."

Yuan Tiangang thought about it and said, "Think this is what you call cause and effect?" Seeing the big from the small, just like Han Feizi said, the embankment of a thousand miles was destroyed in the anthill. ”

"That's pretty much what it means."

After speaking, Li Zheng was a little worried, and glanced at Yuan Tiangang suspiciously, should this guy kill all the butterflies in the world in order to prevent sudden climate changes.

This creates another, very serious ecological problem.

When he said that, Li Zheng regretted it a little, and he was afraid that he was not going to become a sinner for the ages.

Yuan Tiangang nodded and said, "Your analogy is very interesting. ”

"That's right! It's a metaphor! Li Zheng patted his thigh and said: "It's a metaphor, I know that Yuan Daochang will not really kill all the butterflies in the world." ”

"You're underestimating the poor road." Yuan Tiangang said in a chattering voice: "The climate in the world is a kind of cycle, and every catastrophe will be followed by several years of good harvest, which is a kind of reckoning and a kind of mediation. ”
