Le Yi cleaned up the filth on his body, changed into a cyan robe, his face was a little tired, and ordered his subordinates to invite Pang Xuan into the account.

Gu Tu's ability to command a large army in battle cannot be compared with him, but his personal strength is still above him, and he is younger than him. In a short period of time, he can still not fall into the wind, but after a long time, he can't support it.

The peak period of a person is also ten years between the ages of thirty and forty. During this period, his mind and physical strength reached his peak, and he also had a wealth of experience. After the age of 40, although my experience is still increasing, my mental and physical strength are declining. Although the peak period of the Transcendent Realm martial artist will be extended, it will only be ten to twenty years longer.

Le Yi had already passed this peak period, if it wasn't for Gu Tu forcibly attacking the Chinese army, he would definitely not choose to intersect with the opponent's short-handed soldiers.

"I hope that the spirit of the monarchs will not diminish back then." Pang Xuan stepped into the camp tent and arched his hand.

He just learned that Le Yi was facing 150,000 Xiongnu troops and 70,000 Quyan troops, not only did he not lose, but he inflicted heavy losses on the Xiongnu, and even the Xiongnu kings suffered heavy losses.

Although Zhao has always claimed to fight Rong Di to fight one dozen five, one to ten, but it is just a miscellaneous soldier, if it is facing the elite, it is absolutely impossible to do a dozen five, but Le Yi is fighting the elite of the Huns, leading only 30,000 elite Zhao troops and some Rong Di miscellaneous soldiers.

"I'm getting old after all." Le Yi waved his hand, shook his head helplessly and said, "It's still you who are powerful, not only has your strength not declined over the years, but there is an upward trend."

Le Yi and Pang Xuan both worked under King Zhao Wuling, and at that time they were still hairy boys, far from being famous today. The relationship between the two is not good, nor is it bad, it can only be said that they know each other, but as old friends from the same period pass away one by one, the original general relationship has become stronger.

Pang Xuan smiled and said jokingly, "No way, you guys are too dazzling, I can't compare to you at all." Therefore, I can only compare my life with you, and when I boil you all to death, it will be the old man's world."

Pang Xuan not only learned the art of soldiers, but also learned the art of Taoism with Crane Guanzi. Taoism embraces all things, has both the idea of entering the WTO and the idea of being born, and compared with other schools, Taoism pays more attention to self-cultivation.

Don't look at Pang Xuan's age now, in fact, his strength is still growing slowly, and when will he die, and when will his strength stop growing.

According to his words, when all his peers are boiled to death, and the new generation has not grown up, there may not be anyone who is his opponent.

"You guy has bad intentions." Le Yi pointed at Pang Xuan and scolded with a smile, "Okay, stop laughing, get down to business."

"I hope you will speak." Pang Xuan is colorful.

"Although the Xiongnu were defeated this time, it was not a good thing for my Zhao State. If the Xiongnu no longer take the initiative to attack, but choose to defend by the river, or retreat to the north of Yinshan, it will be much more difficult for our Zhao State to destroy the Xiongnu." Le Yi said in a deep voice.

The Xiongnu swept the grassland before, and their self-confidence was bursting, and they had the style of my boss, the second and the third, and hundreds of thousands of troops roared by, wanting to compete with Zhao State, and even to attack the Central Plains.

In this regard, Zhao Guo did not have the slightest worry, but was very happy. Zhao Guo was not worried about the Xiongnu attacking him, how many came, Zhao Guo killed more. I am afraid that the Huns will not come out of the grassland. The grassland is so big, if the Xiongnu retreat to the grassland, Zhao Guo has no way to take the Xiongnu.

If you go on an expedition to the desert, you can't even take out 50,000 troops, and logistics alone can drag Zhao Guo to death.

When he met the Huns, Le Yi thought of this problem. But the arrow had to be sent, if he didn't do his best, he would die by himself and the 30,000 soldiers of the Zhao army.

Hearing this, Pang Xuan's eyebrows couldn't help frowning together, if the Xiongnu really did this, even if Zhao recovered all the Hetao, the strategy would lose half, and then it would still have to deploy heavy troops in the north to defend, and it would be harassed by the Xiongnu every year.

Just like the gadfly on a cow, it can't be driven away, and it can't be killed.

"The Huns shouldn't be so small, he spent so much energy to raise so many troops. It's just a fight. If retreat to the steppe

All the previous efforts have been in vain." Pang Xuan said uncertainly.

"Don't be afraid of 10,000, just in case." Le Yi said.

"What do you mean by looking at the monarchs......" Pang Xuan looked at Le Yi.

"Don't give the Huns time, before the Huns can react, concentrate all your forces and defeat him." Le Yi slammed his fist on the table and said in a deep voice.

No matter what choice the Huns make, sooner or later they will have to fight a decisive battle, and since this is the case, it is better to fight a decisive battle in advance.

"The Great King has already set out from the clouds, and he should be able to reach Jiuyuan within three days." Pang Xuan said.

……

On the avenue leading to Jiuyuan City in the clouds, Zhao Kuo led the army to slowly move towards Jiuyuan City.

"Good job." Zhao Kuo handed the news he had just received to Liu Ping. Liu Ping sorted it out and put it in a bag, which should be archived for future inquiries.

There is news from Handan that the farmer has sent people to try to plant wolfberries in saline-alkali land, and the results are not yet known, but at least the wolfberries have not died. Prima facie, it should be feasible.

The ash tree has also been found, but I don't know if it is the kind of ash tree that Zhao Kuo said, because no ash insects were found on the tree.

In the second half of last year and the first half of this year, Zhao Guo has been building water conservancy projects, turning dry fields into paddy fields, and all these newly renovated paddy fields have been planted with rice.

The yield of rice is much higher than that of millet, but it is mainly cultivated in the Chu State, and in the north it can only be grown in places close to rivers and lakes, with sufficient water sources and perfect water conservancy facilities.

For example, near Yecheng, after Ximen Leopard diverted water from Zhangzhang for irrigation, the yield per mu could even reach ten stones, which was about the same as the output at the end of the 20th century. Of course, this is only a special area, which cannot be generalized and does not indicate the average yield.

Millet is more drought-tolerant than rice, requires less water, and can be grown in places that are not particularly dry, and is the main source of food for people.

As for the land that is planted again, millet does not have high requirements for soil fertility, the yield of fertile soil will not increase too much, and the yield of poor soil will not be reduced too much. During the Warring States period, millet was very high, and it was planted in many mountainous areas where the soil was not so fertile.

Soybeans are planted in the middle and lower fields, soybeans do not eat soil power, rhizobia can also play a role in fattening, no need to rotate, wheat is planted in winter, soybeans are planted in summer, and the yield will not be reduced, and it can continue to be planted next year.
