Longxi County.

To the west of Shangtai County, is the surging Mother River of China, bounded by the river, the west is the Hexi Corridor occupied by the Yueshi people, and in the northwest, the vast grass principle is occupied by the Huns who have just risen, just at the end of the Qin Dynasty, when the Central Plains was in turmoil, the battle for survival between the grassland peoples in the west is also becoming increasingly hot.

Li Yuan in Luo Jia's temporary camp of cavalry on the bank of the river, summoned Bai Guangji, the leader of the scouts who had sneaked into Hexi not long ago, and had not seen him for more than a month, Bai Guangji was up and down, and he could no longer see the shadow of the Central Plains people, except for his nose and skin and obvious characteristics of the Qin people, the rest of the parts, behavior, he was a complete Qiang person.

Bai Guangji entered Hexi with a Qiang tribe that migrated westward, and with him were thirteen other people, all of whom were selected from the army, and they were not only brave, but more importantly, good at camouflage, that is, the kind of people who would not attract attention if they were still in the crowd.

Among Li Yuan's cronies and generals, Bai Guangji is definitely an inconspicuous one. He is not as sharp as Luo Jia, nor is he as shrewd and calculating as Li Bi, and he is not as flamboyant as the one-eyed Cao Xin, he is such a person, but he was uniquely discerned by Li Yuan and selected to be the captain of the most elite scout in the infantry army.

"General, I'm back?" Bai Guang Monsoon was dusty, and he had just crossed the big river, and there was still a smell of sheep on his body, which was a little unpleasant, but a little kind.

"Lao Bai, haha, I haven't seen you for many days, and the days on the grassland don't seem to be bad." Luo Jia stepped forward excitedly and hugged Bai Guangji's sturdy body.

Li Yuan is smiling looking at the intimacy of the two generals under his command, and his heart is also happy for it, Luo Jia, Bai Guangji, Li Bi, Cao Xin, these young people are growing up step by step, they will be the future of Li Yuanjun, and as the leader, Li Yuan is even more happy with the strong true feelings between them.

The love of comrades-in-arms is more precious than anything else.

Even though thousands of mountains and rivers have passed, a long time has passed, and a concern is always entangled in my heart.

"Captain Bai, how is the situation in Hexi?" Li Yuan waited for Bai Guangji to kneel and finish the salute, and began to ask for information about this in-depth visit to the hinterland of the Yueshi Xiongnu.

"General Yu, at the beginning of last month, the Yueshi and the Huns fought a big battle in the area of Gaizang City, and the troops of each side were not less than 50,000 people, as a result, the Yueshi people were defeated, and even the garrison Gaizang City was occupied by the Huns, and now the Yueshi tribe is divided into two branches, one of which moved to the Jincheng area across the river, and most of them moved west to Duncheng and more westerly." Bai Guangji sorted out his thoughts and reported the situation one by one, the rhythm of his speech was not fast, but every word was reasonable and clear, this is exactly what Li Yuan values.

"Is the leader of the Huns called Mao Dun Shan Yu?" Li Yuan tapped on the case, thoughtfully.

"How did the general know that the original name of the Xiongnu tribe was Touman, but he was killed by his son, that is, Mao Dun with an arrow a year ago, this Mao Dun was a hostage in the Yue clan in his early years, and this Xiongnu and Yue clan war was caused by Mao Dun taking the opportunity to seek revenge." Bai Guangji nodded and said.

"In this case, Luo Jia, you must be mentally prepared, your cavalry, the future enemy, is not only the princes of the Kwantung region, but also the evil wolves of the steppe - the Huns." Li Yuan's expression was solemn, and he was stunned, this Hun Da Dan Yu, who made Liu Bang almost commit suicide in Baishan Mountain, appeared in Li Yuan's field of vision, and his existence was a great threat to Li Yuan, who was concentrated in the border area.

"General, don't worry, I, Luo Jia, will not train an elite cavalry army, and I will not return to Yongcheng to see you." Under Luo Jia's pressure, the pride of the young man made him raise his head uninhibitedly and look directly at Li Yuan.

"General, the changes in Hexi are related to the overall situation of our army, I will cross the river to the west and explore the strength of the Yue Clan King again?" Bai Guangji got up, arched his hand and said.

"It's hard work for both of you. On the road to the rise of our army, you have walked all the way, Li is very grateful! Li Yuan bent down and made a big bow to Luo Jia and Bai Guangji, at this moment, his heart was stirred with the thousands of pride of a man's ambition.

——。

At the end of September in the first year of the Qin New Calendar (206 BC).

In the expectation of tens of thousands of Yongqi people, this season's spring wheat began to hang heavy ears of wheat and nodded to the working people.

Although due to the shortage of wheat seeds, Li Yuan only replanted at the forks of rivers and ripe fields in the Yongqi area, and in other places, millet was still the mainstay, and the actual statistical results still made Li Yuan feel excited.

In addition to the wheat seeds reserved for the full promotion of winter wheat in the next season, the spring wheat that was hastily planted this time was pulled out at those specious experience points taught by Li Yuan, and after a variety of shiyan by Zhang Cheng and other grassroots pavilion chiefs and fathers, the yield obtained was 20% higher than the original millet harvest.

Don't look at only two percent of the increment, the increase in crop yield, has a profound impact on the change of human living conditions, every day, go to the field, take a look at the spike of slurry, now it is the habit of Zhang Cheng and other old people.

At the same time, the 30,000 soldiers under Li Yuan's command began to be reorganized for more than two months after the baptism of the Battle of Chencang and the Battle of Poqiang.

In Li Yuan's plan, the future army is mainly composed of five major arms:

First: Luo Jia's cavalry, the abundance of war horses gives the cavalry more choices, and the number of 10,000 cavalry allows Li Yuan's army to dispatch two elite rapid reaction troops at any time. Of course, there were only 3,000 cavalrymen at the moment, which was still a long way from the envisaged number.

Second: Wang Shang's crossbow army, this is a long-range army that follows the tradition of the Qin army, three thousand crossbowmen equipped with bronze machine crossbows, enough to make any opponent fearful, this is a formidable liliang, and it is also the trump card army reserved in Li Yuan's hands.

Third: Jiang Yu's infantry army, this is a conventional liliang, with 15,000 halberd infantry is the main combat liliang, Jiang Yu is calm and moderate, and he is the right person.

Fourth: Bai Guangji's scouts, this is a special operations force envisioned by Li Yuan, their number is not much, less than a thousand, but they have to undertake a variety of combat tasks such as spying, assassination, beheading, ambush, etc., they are also the ancient special forces in Li Yuan's mind;

Fifth: Cao Xin's personal guards, the number of people is about 5,000 people, the main task of this elite army is to protect the safety of the generals, which is not only Li Yuan's safety, but also other important generals in the army, the importance of cold weapon war generals is particularly important, Li Yuan does not want to let the war develop in an unfavorable direction because of the accidental death of a general.
