All the weights and measures are ten sets, Huo Gang gave Sun Erlumu a set of them, let them copy these weights and measures, of course, they can also use them directly, at least the work they have done so far, these can still be used, especially carpenters, they themselves have similar tools.

But now that Huo Gang said that he would implement new weights and measures, Lu Mu and the others will naturally use new tools and units in the future.

After giving these things to Lu Mu and them, after resting for the night, Huo Gang went directly in the direction of Yangguan in the morning.

Gongsun Lin and the others had already returned to Yangguan in advance, and only the personal guard cavalry led by Huo Zheng was following Huo Gang.

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

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

When he stepped on the mountain range where Yangguan was located, Huo Gang was also located at the highest point of Yangguan, and then Huo Gang saw a meandering river, along with the green carpet on both sides of the river, stretching into the distance on the earthy Gobi desert.

This touch of green is so conspicuous that you can't even see the end of its flow when you stand on a high place, and during the time that Huo Gang left, these two small rivers actually flowed so far away.

But if you think about it, it's normal that the expansion of these rivers was slow at first because when they flowed above the Gobi Desert, most of the water seeped into the ground first, because the ground here is very dry.

When the water table rises higher and higher in the places where the river flows, the river water does not seep in, and naturally begins to extend into the distance.

Coupled with the rain that Huo Gang had had had fallen before, the speed at which these rivers expanded even faster.

Before Huo Gang left, with the direction of the river, Wu Ping planted a large number of small saplings, and those saplings were already alive, but those saplings that extended with the river were all green that extended to the Gobi Desert along with the river.

But now, the saplings occupy only a very small part, and more often than not, large meadows of grassland flow along the river and into the Gobi Desert.

"Let's go back and see." Huo Gang pointed over there with some excitement and said, is there anything more exciting than seeing green in this Western Regions?

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

Huo Gang didn't go back to the camp, but went directly to the direction where the river flowed, and crossed the place where they planted trees before, Huo Gang had already recognized that there were alfalfa grass on both sides of the river!

And these alfalfa grasses have grown four or five centimeters tall.

Huo Gang ran along the river for at least a thousand or two meters, and the alfalfa grass on both sides of the river began to thin out, but it could be seen that they were still expanding with the river, Huo Gang grabbed the reins of the horse, turned over and dismounted and walked to the river.

Hongyun behind Huo Gang immediately followed Huo Gang to the river curiously, and when he saw Huo Gang leaning over to check the grass in front of him, Hongyun curiously leaned over his mouth and secretly glanced at Huo Gang, confirming that Huo Gang didn't look here, Hongyun immediately bit a few alfalfa that had just grown directly into his mouth.

After biting these alfalfa grasses into its mouth, Hongyun's big eyes immediately showed happy emotions, and it immediately extended its mouth to other alfalfa grasses.

With a "snap", Huo Gang, who was squatting in front, saw Hongyun's small movements, and directly turned around and slapped it on the head angrily, "Don't you see that they are still small?" When they grow up, even if you come over and eat them every day. ”

Hongyun's big eyes immediately revealed aggrieved emotions, and it stopped eating grass anymore, and directly rubbed its head into Huo Gang's arms.

"Okay, okay, they're still in the growth stage, and they'll be more delicious when they grow up." Huo Gang reached out with some amusement and pulled Hongyun's head out of his arms.

Huo Gang took a closer look, the places where these alfalfa grasses grew were originally the Gobi Desert, but they still grew tenaciously, and it seemed that he still underestimated the role of the stream after integrating into the spiritual spring water.

When Huo Gang checked this, several horses in the camp in the distance galloped towards this place quickly, it should be Anno They saw Huo Gang coming back, and rode directly here.

Huo Gang didn't leave, just waited in place, and sure enough, the person who came was Anno leading Guo Ming and a few of them.

When Huo Gang was still more than ten meters away, Anno and the others directly reined in the reins of the horse, and after directly turning over and dismounting, several people walked to Huo Gang's side and bent down and saluted: "Anno has seen the general, congratulations to the general on his return from a great victory." ”

"Well, you're doing a good job, but why do these alfalfa multiply so fast?" Huo Gang nodded, not politely, pointing to the alfalfa grass by the river and asking.

Hearing Huo Gang's question, Anno couldn't help but remember that they had also asked Wu Ping this question ten or twenty days ago, but in Wu Ping's answer, this river was summoned by Huo Gang with a god-level, so it could make the grass multiply so quickly.

Originally, Anno didn't believe it, but then when Wu Ping planted those alfalfa grasses separately, Anno couldn't help but believe it! Because none of the alfalfa grass planted by these rivers died, instead of dying, they began to expand wildly in all directions after they survived.

Almost overnight, a sizable piece can be reproduced!

"It was about 20 days ago that the weather warmed up and the growth rate of these alfalfa grasses began to accelerate, and then Mr. Wu discussed with us and decided to dig up the whole alfalfa grass that had grown and then plant it in a distance, leaving enough space around each plant for them to reproduce themselves. So they reproduce very quickly. Anno immediately spoke.

Huo Gang immediately understood what they were doing, in fact, it was the same as planting a tree, leaving enough space around it for the alfalfa grass to multiply on its own, so that the speed of the conversation would naturally be much faster than if you planted all the seeds in one place and let it expand from the border.

It's the same as building a road, the way it expands in the first place is that you build a road and start from the end and work your way through.

And now this way is to break a road into countless sections, and then start to build from different directions at the same time, the speed is naturally increased by more than double, in fact, this is alfalfa itself is not considered a grass that reproduces itself very quickly, otherwise, this speed will be even more terrifying.
