Pang Tongyi slapped the table and said: "Yes, since locusts like dry land, I will build water conservancy and the land is moist, so that there will be no locusts to cause trouble?" It turned out that the officials who were able to do the work did not have any locust plagues when they arrived in the locality, because of the construction of water conservancy. ”

Liu Chan nodded and continued: "It's still not possible to repair water conservancy alone, after all, Yongliang is short of water, and there are not many places that can be irrigated, and building water conservancy requires huge manpower and material resources, and it can't be done overnight.

In addition to preferring dry land, locusts also prefer cereals, wheat, rice, sorghum, etc., so they can not grow these crops in places where there is a shortage of water, and plant soybeans and fruit trees instead. ”

When Pang Tong heard this, he hurriedly wrote it down, it turned out that in addition to building water conservancy and destroying the soil for locust breeding, you can also start from the crops, if you like to eat grains, I will plant something else.

Liu Chan said: "Also, as I just said, locusts lay eggs in dry and bare land, and the Yongliang land is generally like this, so that the land can be renovated in winter and the eggs in the land will be frozen to death.

However, this can not completely exterminate them, chickens and ducks are the natural enemies of locusts, let the people raise more chickens and ducks, put them in the field, chickens and ducks eat the eggs in the land and become fat and weight, chicken and duck feces can also fertilize the land, killing two birds with one stone.

In addition, in an open and dry place that is not farmland, there should also be a variety of trees, so that locusts can be controlled, and not only that, but also sandstorms and soil erosion can be prevented. ”

Pang Tong raised his head and looked at Liu Chan with a puzzled face: "Prevent wind and sand?" Soil erosion? Your Majesty, what is this? ”

"This is related to the Mohist thought, when I was in Yizhou, I saw the people cut down trees, cut down all the trees on the mountain, and then the sky rained heavily, the landslide and the ground cracked, and the villages located at the bottom of the mountain were washed away by mudflow.

This is the cause of soil erosion, the trees take root in the land, the trees are cut down, the roots of the trees die, so the land becomes soft, and when the heavy rain comes, the mountains and forests will naturally collapse...... "Liu Chan did not push, but patiently explained.

Nowadays, there are still boundless mountains and forests in Yongliang Pass, but after two thousand years, it has become the Loess Plateau, and as for Liangzhou, the wind and sand are even more serious.

At present, although this situation has not yet occurred in the land of Guanzhong, if it is not prevented, sooner or later it will follow in the footsteps of history, so Liu Chan has the responsibility to preserve this precious wealth for future generations.

Pang Tongyi listened and wrote it down, and after Liu Chan finished speaking, he put down the brush in his hand, and the rice paper on the table had been recorded.

Pang Tong shook his sour arm and said: "I didn't expect Your Majesty to know so much, according to the ancient scrolls, during the Qin period, the land in Guanzhong was fertile, the climate was humid, and there were boundless forests.

The former Han Dynasty took Chang'an as the national capital, the population increased dramatically, countless mountains and forests were destroyed, and now, the land is dry, and the locust plague has been plagued for many years, which seems to have something to do with this. Weichen has gained insight today, we can't do our best to fish, we have to think about future generations.

The theory of the sage Mozi is indeed not unreasonable. ”

Liu Chan nodded and said: "Not only that, but also to plant forests extensively, not indiscriminately cut down, and land reclamation must also have a plan." I intend to establish a Ministry of Resources to manage local resources and make rational use of them.

If it is not used reasonably, there will be natural disasters, and when natural disasters are combined, the people will be displaced, the people will be dissatisfied, and the country will be safe for a long time. But there is no need to rush this matter, wait until I return to Yizhou, if it is dark today, Aiqing will stay and dine with me. ”

Pang Tong arched his hand and said: "Thank you Your Majesty for your kindness, but it is more important to control locusts, the people of Yongliang are poor, if the people renovate the land in winter, grain and grass, ploughing cattle, farm tools, etc., the government will help provide them, and Weichen will go down first to discuss with Xu Tingshi to convene officials to discuss, and he will not disturb His Majesty's meal!" ”

Liu Chan nodded, and did not force him to stay: "Then it will be hard to love Qing." ”

"Wechen retires!"

At present, it is a cold winter, and the Qiang people have immigrated to build a city and establish a pasture on the grassland, and Liu Chan has not yet started to deal with it, but has arranged for soldiers and horses to set up kilns in various parts of Jincheng and burn cement to prepare for the construction of a city in the grassland.

At the same time, he also ordered Xu Miao to inventory the land in Liangzhou to prepare for the migration of the Qiang people.

As for the people of Yongliang, they also responded to the call of the government, and with the help of the government, renovated the land in winter and exterminated locusts.

However, during this time, Yuzhong gradually became lively.

The liveliness of Yuzhong comes from tribute.

Now Liu Chan got the land west of Liupan Mountain, the Qiang tribes on the border of Yongliang, have sent envoys to pay tribute, and at the same time scouts to report, the Western Regions Zhuhu also sent envoys, but the Western Regions are far away, still on the way.

These forces, Liu Chan will be destroyed sooner or later, but at the moment Liangzhou is still in development, it is not yet time, Liu Chan met with the envoys of these forces one by one, and while accepting their surrender, he is also understanding their forces, preparing for the pacification of the Qiang people and the pacification of the Western Regions in the future.

In the early morning of this day, Pang Tong found Liu Chan and reported: "Your Majesty, the envoy of the Cheshi Kingdom of the Western Regions asks to see you. ”

Liu Chan smiled when he heard this: "Oh? The envoy of the Cheshi country has arrived? ”

Pang Tong arched his hand and said: "Out of the Yumen Pass to the east, is the country of the car division, the country of the car division is divided into the front division and the rear division, the messenger here is the front division." ”

Liu Chan said lightly: "The Cheshi country is sandwiched between my Han and the Huns, and the former Han is a number of rebels, I don't know if this time, whether it is really attached." ”

Pang Tong smiled when he heard this: "The Southern Xiongnu have long been attached, and now the Northern Xiongnu have moved west to the west of the Tianshan Mountains and arrived in the area of Dawan Kangju. To the north of the Cheshi country is Xianbei, but Weichen thinks that His Majesty wants more than just annexation, right? ”

Liu Chan smiled faintly and said: "When the Xiongnu come, the countries of the Western Regions will be attached to the Xiongnu, and when our Han army arrives, they will be attached to the Han Dynasty, capricious, how different from the Qiang people?" I want them to be like the Qiang people, and completely become my Han people.

However, if you want to completely take over the Western Regions, you must first govern Liangzhou, otherwise you will be powerless. But I can first place forces in the Cheshi, and pass on the envoys of the Cheshi country to meet them, and I will see them first. ”

"No!"

At this moment, an attendant suddenly ran in in a hurry: "Your Majesty, Yizhou is urgent." ”

"What's going on!" Liu Chan's face changed when he heard this, and he hurriedly strode down the hall and took the letter from the attendant.

"Hahaha!" After reading the letter, Liu Chan suddenly burst out laughing.

"Your Majesty......" Pang Tong wanted to read the letter when he saw this.

Liu Chan handed the letter to Pang Tong and said with a smile: "Here, double happiness is coming, I have won Yongliang, and the three concubines in the family are also pregnant with children." The messenger of the chariot master disappeared first, and gathered the civil and military ministers, let's celebrate and celebrate. ”

Pang Tong read the letter and was also excited: "Congratulations to Your Majesty, congratulations to Your Majesty, my Han has added three princes, and it is really a double happiness." ”

"I've just been pregnant, and it's only three months when I count the time to deliver the letter, so it's hard to say how many princes there are." Liu Chan waved his hand and said: "But the first emperor just went this year, and the two mothers were unwell under grief, and now that the prince is about to be born, he can be overjoyed." ”

"The two queen mothers will definitely be cured, Weichen will go to gather the civil and military, the three generals know, I am afraid that I will have a good drink again today."
