This is a small mountain col, in an east-west direction, there is a river in it that passes through Yang Heng's princess village to the east, and then flows into Weishui, which means that it is not far from Yang Heng's princess village, it is a little north in the west.

Why do you want to say this place, this place is a place with beautiful mountains and rivers and beautiful scenery, but that was after spring, now, this place is also good, the stream has long been thawed, and the sunny places in the north of the col have begun to appear green, Yang Heng also occasionally passed through a forest and came to this place, when he found this place, he liked this place, so he quickly made a report, wrote an application, and sold this place.

The local county government is very fast, can it not be fast, this is the horse master wants to buy land, and the county government is quite happy, a place where no one wants, finally got rid of it, and got some silver money for nothing, if Yang Heng just occupied this place, the county government would not have any opinions, a col that can only produce firewood, it is its great luck to have someone to ask for it.

But what does Yang Heng want this place for, even, this place is still under the name of the princess, what are you doing, it is naturally a place to try out, and do some research, you look at the sunny side of the north, because the mountain pass is blocked by the woods, so it is difficult for the wind to blow in, the northern slope of the mountain comes earlier than the spring in other places, and it can even be half a month to a month in the morning, that is, winter, it will come later, is this suitable as a research base for improved seeds? There are still dozens of acres of land on this hillside, if you talk about these dozens of acres of land. Others have no way to farm. But Yang Heng has a way. Isn't it just a lack of water, there is a stream flowing down from the mountain in the distance, and it is a little difficult to open a tunnel, but if you build a pipe, it will be a simple thing, what, make a water pipe with iron, stupid. The water that can flow naturally also needs iron pipes, and you only need to use bamboo to open the joints inside, even if it is made of wooden boards, it will also be made into a simple channel, so you don't need to waste materials everywhere.

When the pipeline was completed, it was also the time for the official launch of the improved seed test base, and a few old farmers who were very good at agriculture were arranged to move here to live and supply food from time to time. Meat, and some other daily necessities. They happily settled here.

However, Yang Heng does not plan to let them live permanently, and after a certain period of time, he will still let them move out, but some confidentiality measures still need to be had. Secrecy, for this valley, it is very convenient, the mountains around the valley are relatively dangerous, in this way, it is not very easy for someone to want to lurk in, Yang Heng only needs to arrange some sentry posts on the surrounding mountains to solve it, and even Yang Heng asked Li Er to arrange some surveillance personnel in the periphery, but these things are carried out in secret, and there is no archiving and publicity, naturally in this era, there will be no future generations of travelers who can come to climb the mountain, basically safe, The sentry is a bit redundant, but this system still needs to be had, and even Yang Heng arranges people to carry out some harassing work from time to time, so that the sentry can fulfill their duties.

It would be a bit wasteful for such a large valley to be used only as a base for improved seeds, so in some of the innermost places, Yang Heng arranged for people to carry out construction, that is, to level some places, and then build some thick stone houses, and even the cement was transported in manually.

If there is no explosives, how to open the mountain, this is easy to do, use fire, and water to break the rocks, and then use hammers and wedges to clean out the rocks, although there is no gunpowder here, but these houses are related to gunpowder.

As a traverser, if you don't develop gunpowder, it will be too much of a failure, so now Yang Heng has put gunpowder on the agenda, and even asked Sun Laodao to find a few poor Jianghu warlock type veterans to work, but it is just a signed death contract, how many years to work for Yang Heng, if they don't reach the age limit and secretly leave, Yang Heng will let people chase and kill them, which uses lure and coercion.

The reason why Yang Heng came to these Taoist priests is that since these Taoist priests can be warlocks, they can explain some chemical things, but since they are poor, this disease does not mean that their skills are not proficient, but that they can't operate, and even they are more skilled than those Taoist priests who can operate.

Yang Heng just wanted to give these Taoist priests some benefits to tempt them, and then use coercion to scare them, and they would stay here safely and study chemistry.

"Yang Heng Xiaoyou, Lao Dao has a small request, you see?" Sun Laodao was a little embarrassed to open his mouth to Yang Heng, it seemed that he had something to ask for, but he was a little embarrassed.

"Daochang Sun, if you have something, don't hesitate to say it," Yang Heng believed that Sun Simiao would not propose anything excessive, you must know that Dao Lu is a healer who cherishes feathers very much.

"Then the old way said, the old way looks at the place where the reclaimed land in your valley is located, it is just right for the old road to plant some special medicinal materials, which are some medicinal materials that are relatively rare in the south, I think the climate of this place is just right, little friend, you see." "Hmm." Yang Heng was thinking about that place, where he could grow medicinal herbs, but Sun Simiao reminded him that this place could not only cultivate some grain seeds, but also be used to grow medicinal herbs.

"Xiaoyou, isn't it very difficult, the old way only needs one acre of land, ah, no, half an acre of land." Lao Dao was a little anxious, "Daochang Sun, don't worry, it's not that I don't want to use it for you, but I'm thinking about it, there are better places on the mountain, it's just a little too difficult." "Where is it, take the old way to see it now." "Sun Daochang, don't worry, you can't run in this place, those places are a little fragmented, they are some potholes on the mountain, the soil on them is very deep, and even some humus soil, which is suitable for planting medicinal herbs, even if there is no shortage of water, there are trickles flowing into those places all year round in the cracks of some mountains and rocks, even if the weather is dry, it will not dry up."

As the saying goes, how high the mountains are, how high the water is, in the gaps of these mountains and rocks is fully demonstrated, Yang Heng does not need to investigate, you can know the road, these trickles are through some tiny gaps between the mountains and rocks to infiltrate, and these water sources do not know how deep the road is, these water quality is still very good, if there are more, Yang Heng wants to make wine here, at this time what mineral water is fake, in an era of no pollution, what mineral water to drink, And mineral water is everywhere, and if you make good use of the water quality, you can only use it to make wine, but unfortunately the flow is too small, Yang Heng had to shake his head helplessly, when Sun Simiao wanted to plant medicinal materials, he just reminded him, if you use these water to water the medicinal materials planted, will the effect of medicinal materials be better?

"Okay, good, it's such a soil quality, the problem that Lao Dao has not been able to solve is now solved, in the past, if you want to use some special medicinal materials, you need to go to the south to dig yourself, this time is a waste of time, now it's okay, you can plant it here, Lao Dao has collected some seeds, and now I'll hand it over to you, if Lao Dao wants to use medicinal materials, I'll come to you to talk to you." Lao Dao is very excited, a problem solved, how many patients will he treat.

"Daochang Sun, I suddenly had an idea, if we build a medical hall outside the woods at the foot of the mountain here, let the sick live here for treatment, and also, mine some ordinary medicine fields outside, wouldn't it be much more convenient for us, and you can also teach a few apprentices to inherit your mantle."

Suddenly, Yang Heng remembered the hospital in the future, in this way, not only can he help some patients who need help, but also the patients can also have a fixed place to seek medical treatment, Yang Heng can also use this to cover up some things about some tests in the valley, the more Yang Heng wants to feel that this idea is more correct, and he can also collect some diseases related to Li Er's body, so that Li Er can continue his life at that time, and let Changle not die prematurely, Yang Heng is especially worried about Changle's body.
