"General." Wu Ping was at the front of the crowd, and when Huo Gang arrived, he took the lead in saluting, and the ordinary people who followed Wu Ping also did the same, saluting Huo Gang in a mess.

"You're welcome, Mr. Wu, you let people go to the front to help drive the cattle and sheep back." Huo Gang nodded, pointed to the flock of sheep behind him that was still far away, and spoke.

"It's the general!"

Wu Ping quickly commanded the crowd behind him to help drive the sheep in the distance, and he also took the opportunity to let the cattle and sheep disperse.

After Wu Ping finished dealing with it, Huo just opened his mouth and asked, "Mr. Wu, has something happened at home?" ”

"Yes General...... It's a good thing, the general comes with me. Wu Ping thought for a moment before he spoke decisively.

A young man next to him had already handed over a rein, although Wu Ping's hair and beard were already white, but his body bones were still neat and turned over on the horse, this was an old horse, and the speed was not too fast, Wu Ping directly led them directly through the center of Yumen Pass, and walked towards the oasis in the north.

When Huo Gang and the others came to the north of the city, Huo Gang saw a touch of green in the north of the city for the first time, not the reeds in the oasis before, but a touch of something very familiar.

"Is this alfalfa grass?" Huo Gang asked with some consternation, is there already alfalfa in this era? Huo Gang really didn't know this, but Huo Gang knew the alfalfa in later generations, and his grandfather once planted half an acre of land as feed for sheep.

Alfalfa is one of the high-quality forage grasses, although it is not considered one of the top ten forage grasses, mainly because its yield is not as much as the top ten high-quality forage grasses such as imperial bamboo grass, but alfalfa grass also has its advantages, that is, it is very nutritious and is a perennial herb.

Basically, it can be harvested after planting, and it can safely overwinter at temperatures of minus 30 or 40 degrees, it is drought tolerant, it has high yields and very good quality, and it can improve the soil.

Huo Gang really didn't know that alfalfa actually existed in the Tang Dynasty, but he was sure that when he came to Yumen Pass before, the oasis in the north only had ordinary grasses such as moss and reeds suitable for growing here.

"Yes, General, we had saved a little alfalfa seed before, and I tried to plant a little, but in just one day, it had not only sprouted and unearthed, but had already spread itself." Wu Ping said as he looked at Huo Gang's expression.

However, he didn't see anything, because although Huo Gang was a little surprised, there were not too many emotional fluctuations on his face, no matter how big the change was, could it be as big as the change that Hongyun changed overnight?

Looking at this alfalfa grass that was about a few square meters in size, Huo Gang pondered for a moment, and then said, "Mr. Wu." ”

"Old decay." Wu Ping immediately bent over.

"I won't hide some things from you, these alfalfa can have such a growth, it has a lot to do with this water source, which is also one of the biggest abilities of this water source, I have brought back some cattle and sheep, some can be added to the meal, and some can be raised by people, just drink the water in this water source, including Wang Shan and their horses."

"In addition, other grains can be planted according to your planting experience for the time being, but the seeds of this alfalfa grass can be planted directly, as many as you want, and try to expand it to those gravel fields, because alfalfa has the ability to improve the land."

"In a few years, these places will be fertile land for growing food, and in the intervening years, alfalfa will also be used as food rations for the cattle, sheep and horses we raise." Huo Gang didn't explain anything, but said very simply.

Wu Ping raised his head and glanced at Huo Gang a little weirdly, although Huo Gang was their major general, it could be said that Huo Gang was Wu Ping and they grew up.

Although grain can also be grown in this Western Regions, there is not much land that can grow grain, and Huo Gang didn't have the opportunity to understand these things before, but now he even knows the knowledge of farmland such as alfalfa grass can fertilize the land.

You must know that this kind of farming knowledge is only known to some old farmers, and Huo Gang definitely didn't have the time or energy to understand it before.

However, Wu Ping didn't ask about this, he pondered for a while, then thought about it, bowed down and said: "General, the old man has a request and some words, I don't know if I should say it or not." ”

"Mr. Wu, but it doesn't hurt to say it." Huo Gang directly returned to his senses and said.

"That, General, I still have something to do in the city, I'll go and get busy first." When Wang Shan next to him heard this, he immediately spoke.

Huo Gang glanced at him and nodded, and Wang Shan turned around and patted his horse away.

There are only two people left on this shore, Wu Ping and Huo Gang.

"General, I think the general has great ambitions, I'm afraid it's not just as simple as leading us people to survive in this Western Regions, is it wrong to say that the old man is wrong?" Wu Ping raised his head, his somewhat cloudy eyes were extremely bright at the moment.

"That's right." Huo Gang didn't hide this, if they just survived, they couldn't resist any risk, how chaotic this Western Regions was, Huo Gang, who had Huo Qu's lifelong experience, knew very well.

"In this case, what the general needs is a large number of people under his rule, and in this Western Regions, we Han people are the best choice, I think since the general led us to leave from Yumen Pass, I am afraid that he will not throw himself into the Tang Dynasty again, is it wrong to say that the old man is wrong?"

"That's right." Huo Gang looked at Wu Ping, although there was no expression on his face, but he was surprised in his heart, this is an ordinary old man? Although it can be seen from Wu Ping's dress that he is a cultural person, he must not be a celebrity.

An ordinary scholar has such an eye? Even Huo Gang didn't know whether Wu Ping was a Confucian or not.

"In this case, although there are many Han people in Liangzhou and even around us who can't survive, as long as we are strong, there are many Han people who defect to us, but these populations are bound to be insufficient, I think there will be a large number of Fanbang population under the general's rule in the future, and the number may even exceed the Han people. Wu Ping bowed down again and asked.

Huo Gang paused, to be honest, Huo Gang himself couldn't be sure, but don't think about it, as long as they are strong, there will be Turkic tribes who defect to them.

For those ordinary herders, their needs are no different from those of the ordinary people of the Han people, just to survive.

"I can't be sure, but it can't all be Han Chinese." Huo Gang paused for a moment and then said, if there is a choice, of course the Han people are the best, but the second emperor of the Tang Dynasty is the famous Tang Taizong in history, I dare not say how great his merits are, but at least, in the Tang Dynasty during this period, the Han people are still alive and well compared to this era.

As long as they live well and can survive, it is impossible for these people to flee with their families.

Besides, even if there is, Datang will not allow a large loss of its population.
