All weights and measures are set ten. Huo Gang gave Sun Erlumu and the others one to imitate these weights and measures. Of course, they can also use them directly. At least the work they have done so far can still be used, especially carpenters, who have similar tools themselves.

But now that Huo Gang said that he would implement new weights and measures, Rumu and his team would naturally use new tools and units in the future.

After giving these things to Rumu and the others, Huo Gang went straight to Yangguan in the morning.

Gongsun Lin and the others had already returned to Yangguan early, and the only ones who followed Huo Gang were the personal guards led by Huo Zheng.

This place is not very far from Yangguan. When Huo Gang rode his horse to the high ground where Yangguan was located, he didn't know why he felt an inexplicable expectation in his heart.

At least Yang Laowu told him that Yangguan has changed a lot.

After stepping onto the mountains where Yangguan is located, Huo Gang is also at the highest point of Yangguan. Then Huo Gang saw a winding river, and the grass on both sides of the river stretched out into the distance on the yellow Gobi Desert.

This touch of green is so conspicuous that you can't even see the end of it flowing when standing at a high place. During this period, Huo Gang left, these two small rivers actually flowed so far away.

But if you think about it carefully, it is normal. At the beginning, the reason why these rivers expanded slowly was because when they flowed to the Gobi Desert, most of the river water first penetrated into the ground because the ground here was very dry.

As the groundwater level becomes higher and higher in the place where the river flows through, the river water no longer seeps in, it naturally begins to extend far away.

With the rain that Huo Gang had hit before, these rivers expanded faster.

What surprised Huo Gang was the green on both sides of the river. Before Huo Gang left, Wu Ping and his friends planted a large number of small saplings in the direction of the river flowing, and the saplings were alive, but the saplings that extended with the river were all green on the Gobi Desert along with the river.

But now, those saplings only occupy a very small part, and more should be large areas of grass flowing into the distance with the river and stretching into the Gobi Desert together.

"Let's go back and take a look." Huo Gang pointed to the other side excitedly and said, "Is there anything more exciting than seeing green in the Western Regions?"

Following Huo Gang's words, Hongyun ran away, and Huo Zheng and the others hurriedly followed behind.

Huo Gang did not return to the camp, but went straight to the direction where the river flowed, and passed the place where they planted trees before. Huo Gang had already recognized that the sides of the river were actually alfalfa!

Moreover, these alfalfas have grown by four or five centimeters.

Huo Gang ran at least one or two thousand meters along the river, and the alfalfa grass on both sides of the river began to become sparse, but it was obvious that they were still expanding with the river. Huo Gang tied the reins of the horse, turned over and got off the horse and walked towards the riverside.

Hongyun behind Huo Gang immediately followed Huo Gang to the river with curiosity. When he saw Huo Gang leaning over to check the grass, Hongyun curiously turned his mouth over and glanced at Huo Gang secretly, confirming that Huo Gang didn't look here, Hongyun immediately bit a few of the newly grown alfalfas directly into his mouth.

After biting these alfalfa grass into his mouth, Hongyun's big eyes immediately showed a happy mood, and it immediately stretched its mouth towards other alfalfa grass.

With a "bang", Huo Gang, who was squatting in front, saw Hongyun's small movements, turned around and patted it on his head with anger, "Didn't you see that they are still small? When they grow up, even if you come to eat every day."

Hongyun's big eyes immediately showed a feeling of grievance. It stopped eating grass and rubbed its head directly into Huo Gang's arms.

"Okay, okay, they are still in the growth stage now, and they will taste better when they grow up." Huo Gang stretched out his hand with some amusement and pulled Hongyun's big head out of his arms.

Huo Gang carefully checked. The places where these alfalfas grow were originally Gobi Deserts, but they still grew tenaciously. It seemed that he underestimated the role of the stream after being integrated into the Lingquan water.

When Huo Gang was checking these, several horses in the camp in the distance were quickly running towards the place. It was probably because Annuo and the others saw Huo Gang coming back and rode their horses toward the place.

Huo Gang didn't leave, but just waited on the spot. Sure enough, the person who came was Annuo, led Guo Ming and others.

When Huo Gang was more than ten meters away, Annuo and the others directly tied the reins, turned over and dismounted, and several people walked to Huo Gang and bent down and saluted, "Annuo has seen the general, congratulations to the general on his return from great victory."

"Well, you guys are doing well, but why do these alfalfas reproduce so quickly?" Huo Gang nodded, and asked without hesitation, pointing to the alfalfa on the riverside.

When Annuo heard Huo Gang's question, he couldn't help but remember that they also asked Wu Ping this question more than ten or twenty days ago, but in Wu Ping's answer, this river was summoned by Huo Gang with the god level, so it can make the forage reproduce so quickly.

Annuo originally didn't believe it, but when Wu Ping and the others planted the alfalfa grass separately, Annuo couldn't believe it anymore! Because none of the alfalfa grass planted by these rivers died, not only did not die, but began to expand wildly to all directions after survival.

It can reproduce in almost overnight!

"It was about twenty days ago that the weather had warmed up, and the growth rate of these alfalfa grasses began to accelerate. Later, after discussing with us, Mr. Wu decided to dig out the entire alfalfa grass that had grown and then plant it in the distance. Each plant left enough space for them to reproduce by themselves. So they reproduced very quickly." Annuo immediately spoke.

Huo Gang immediately understood what they did. In fact, it was like planting trees, leaving enough space around for alfalfa to reproduce itself. In this way, the speed was naturally faster than if you plant all the seeds in one place and let them expand from the boundaries.

This is just like building a road. The way it expands at the beginning is that you build a road from one end to the next.
