In addition to mold, only the cold winter, especially heavy snow, can dry out the locust eggs. The small locust plague in the first year of Zhenguan developed into such a huge locust plague precisely because of the drought that lasted in summer and winter, and the abnormal weather in winter.

The reason for the heavy snow and severe cold can be said to be heard, mold, forget it. In this era of spitting and nailing, you have to find enough evidence for yourself to say anything. Sun Simiao, who can still be suspicious after listening to his words, is actually very face-saving. If you change someone, you will definitely brush your sleeves away, leaving comments such as "nonsense" and "I don't know what to say".

Being lazy is something that only the superior can do. After designating the land of the academy, Li Chengqian handed over the task of leveling the land to He Shou and Yu Qiusheng, and then went on to do his own business.

At the edge of Weishui, Chang'an and Wannian mobilized people to build shelters for the victims to temporarily shelter from the rain. It's summer now, not winter, as long as there is a shelter from the wind and rain, people can live. The victims who traveled to Chang'an from other places in Guanzhong to ask for a bowl of rice to eat would be introduced to Weishui by the local people as long as they entered the counties around Chang'an.

Li Chengqian's choice of address for the college was a flat piece of land near Weishui, near Chang'an. If the ground is uneven, it is necessary to dig the soil, which is more labor-intensive.

It's just that he still forgot that this is an ancient time where everything depends on handwork.

Although the land is flat, there are many weeds and trees on it.

This is not the future of bulldozers and excavators, and there is only one way for the victims to deal with the big trees, and that is to dig. As for the grass, it can only be pulled out and then dug up. Because the prince ordered that grass should not grow on this piece of land, after picking out the grass roots, the soil on the ground had to be "fried" or "steamed" before it could be spread on the ground.

I don't know if I don't see it, and I'm shocked when I see it.

Li Chengqian, who saw with his own eyes that the victims of the disaster had made a simple matter so complicated, was shocked. Lao Tzu wants to establish an academy, but it is not to build a Tongwan city that can sharpen knives and guns, nor is it a project for Emperor Yang of Sui to dig the Grand Canal. You don't have to work so hard, just get the grass away and lay cement on the ground. Recommended Reading: /.. /

"What is cement?"

Yan Liben, who followed Li Chengqian to the bank of the Weishui River, was puzzled.

Thanks to the Prince's blessing, the pockets of the craftsmen who will serve as prisoners have never been so bulging. The construction of the Chongwen Pavilion in the past made these craftsmen unsatisfied. Now that I heard that the prince was going to build a bigger academy, how could I not be excited. Yan Lide still needs to be in charge of the prison headquarters, so it is Yan Liben who brings the craftsmen to help.

Looking at Yan Liben's confused appearance, Li Chengqian couldn't help but hammer his head. Or will he inadvertently bring the thoughts of later generations to the Tang Dynasty. Cement seems to have only arrived in China during the Guangxu period. It's ridiculous to say, obviously my Huaxia was able to produce lime as early as the Han Dynasty, and even back to the Zhou Dynasty. As a result, cement was introduced to China from abroad.

"It's lime mixed with clay, and it seems that there is iron ore powder, so it is made, but the formula ratio is forgotten. Cement is one of the best building materials after water, and it is very strong when it dries. How can I be a prisoner and not know it? ”

Yan Liben still shook his head: "Lime Weichen knows, but this is the first time I've heard of cement. Your Highness is not in a hurry, Wei Chen will take the craftsman to try it, and he will definitely get this recipe out. ”

After flickering away Yan Liben, Li Chengqian sat on the ground in annoyance.

When I was young, I was embarrassed to ask the dean about what I wanted to buy, so a group of children went to the lime kiln outside the county to pick up lime slag to earn money. It was also at that time that he inquired with the potter about the composition of cement. When delivering food, the cement formula can be used for a fart, as long as you know that this thing can be bought. Who would have thought that now that he has traveled to the Tang Dynasty, he can do a lot of things with this secret recipe alone.

The guards led by the prince didn't know why the prince was so annoyed, but they were all rough people and didn't know how to solve it, so they could only silently guard around.

"The grass people meet His Royal Highness the Prince!"

"Wechen see His Royal Highness the Prince!"

"His Royal Highness the Crown Prince...."

Wearing a light yellow robe belonging to the prince to go out, this is a disadvantage, whether it is a commoner or an official, when he sees this shirt, he can immediately judge the identity of the prince.

It's nothing if it's just a bow and a thank you to the victims, or a salute and a show of admiration by the officials. But being blocked by a smiling Taoist priest and swept all over his body by an almost see-through gaze was too much!

Ignoring the knives drawn by the guards, the Taoist priest made a salute: "Yuan Tiangang pays a visit to His Royal Highness the Prince." ”

Yuan Tiangang?

If someone else heard that this guy reported to his home, he might have bowed and worshipped, but Li Chengqian didn't care. In later generations, those who walked the streets and alleys were accustomed to seeing fortune tellers, fortune tellers, and even saw old men who miscalculated fortunes and were hunted down.

After all, this world is still dominated by people, immortals? How could it exist?

Although he has experienced soul piercing that is difficult to appear in dreams, Li Chengqian still does not think that there are immortals in this world.

Thinking of the joke of "yellow robes and big fish and meat", Li Chengqian smiled and arched his hand to Yuan Tiangang: "It turned out to be Yuan Tianshi, lonely, polite." ”

Seeing that the prince did not dislike his status as a Taoist priest, but returned the courtesy, Yuan Tiangang was suddenly shocked.

Now he has not yet made a name for himself, although he presides over the Laojun Temple and is still the leader of the Taoist priests in the world, but the emperor is not interested in him.

It was only in the sixth year of Zhenguan that the emperor recalled Du Yan, Wang Qi, and Wei Ting, who had been exiled due to the implication of the crown prince Li Jiancheng, from Wangzhou, and learned about Yuan Tiangang's miracle from these three people, and then regarded him as a think tank.

"I saw that Yuan Daochang was looking at Gu just now, but what did he see in Gu?"

I have to ask, Li Chengqian plans to see if this guy is really as rumored to blow up the sky.

Yuan Tiangang smiled: "Although Poor Dao has the ability to look at the face and count the blessing and misfortune, but he can only look at some appearances. His Royal Highness the Crown Prince is a prince, and he has his own luck to protect him, just looking at his face, he can't see anything, he has to touch his bones. ”

"Presumptuous!"

Without waiting for Li Chengqian to answer, Yu Tai jumped out.

As a veteran on the battlefield, he could naturally see that this Taoist priest was not as weak as he looked, and he was probably also a master of martial arts. If such a person wants to get close to the prince's body, I'm afraid it's not that simple.

Li Chengqian stretched out his hand to stop Yu Tai and said with a smile: "Since the Taoist chief has this thought, Lone will let you touch it, but okay, if you can't calculate it accurately, be careful that Lone will smash your signboard when the time comes." ”

Yuan Tiangang laughed, indicating that he didn't care.

Under Yu Tai's eagle-like gaze, Yuan Tiangang was first thoroughly searched by the guards before he was allowed to approach the prince.

Stretching out his hand, Yuan Tiangang groped Li Chengqian's shoulders, arms, head, and back of his spine. If you can rewind the time, you can find that his set is no different from the body search just now.

It was only after touching his ankle that Yuan Tiangang withdrew his hand, took a few steps back and returned to the position just now.

After closing his eyes and reciting a scripture that he didn't know what it was, Yuan Tiangang opened his eyes: "Your Highness, the old Tao has a saying, not only should it be said. ”

Li Chengqian nodded.

"Your Highness has three calamities in his life, one of which has been fulfilled, and it is a disaster of falling from a horse. The second is the disaster of the brothers' wall, and the third is the disaster of the old man falling. In addition to these three calamities, he is rich and noble, and if the second calamity is not fulfilled, His Royal Highness will become a generation of benevolent monarchs. ”

Seeing a trace of weirdness at the corner of Li Chengqian's mouth, Yuan Tiangang added: "Your Highness, don't think that it is old nonsense, how it is, you have time to prove it." ”

Li Chengqian turned around with a smile and said to Tai, "Send." ”

Seeing Yu Tai coming over with his thick arm, Yuan Tiangang sighed, thinking that the prince was dissatisfied with the hexagram of "brothers' wall", so he could only turn around and leave.

Sitting on a big rock, after estimating that Yuan Tiangang had walked away, Li Chengqian laughed loudly.

What is good at "Fengjian", depending on the sound of the wind and the direction of the wind, you can judge the good and the bad, and you are proficient in physiognomy, six and five elements, etc., Du Te Niang is nonsense.

Falling from a horse? When Lao Tzu fell from his horse, Chang'an was in an uproar, and everyone in Chang'an knew it. Mixing known things into hexagrams is really unprofessional.

Brother wall? There is a high probability that this kind of thing will happen without counting! The little green finch is only one year behind herself, and she has been known for her intelligence since she was a child. Whether it is himself or Qingque, they are all compatriots of the same mother, and they can get the support of the eldest grandson family, so the position of the crown prince cannot fall into the hands of other princes. This bastard probably decided that Li Tai would still covet the position of the crown prince as he did in history.

It's just that he doesn't know that Li Tai is now a complete follower, and he respects his eldest brother very much, which is not what he was on the original historical trajectory at all.

As for the disaster in old age, at that time, whether it happens or not, I am afraid that I will forget about the fortune telling. Besides, as long as it is an old man and an old lady, such a disaster may happen, and you can count it?

As for the generation of Mingjun ....

Just assume that this guy is farting, I guess he is a compliment to everyone, and then make some specious words to confuse the public. If you are accurate, you will naturally respect him, but if you are not, in this era of closed news, even if people speak ill of him, as long as it is not within the scope of Chang'an, the voice will not come out of the second village.

The god stick is the god stick, it looks like the hexagram is quite accurate, but in fact it is all nonsense.

With such a historical celebrity making a fool of himself in front of him, Li Chengqian's mood couldn't help but feel much better. Looking at the people on the construction site pulling the roots of the tree with their horns, they don't feel unbearable.

And what about with bare hands? My Chinese people are so capable, what Great Wall, what canal, isn't it all realized in these rough hands?

As long as we sprinkle some gold on the development of science and technology from now on, who said that the industrial revolution must rise abroad?
