On the west side, against the iron fence of the iron courtyard, a house was built, although limited by tools and materials, it was still rough and simple, but it could be regarded as a house, much stronger than the kennel-like shack built by Gu Yi, and it was in the shape of a large bunk as usual, enough to sleep one hundred and twenty or thirty of them.

The south side was built all the way to the river, and a shed was also erected, and ten large stone mills were placed here, and some space was left in advance, and the miners did not know what it meant, but Gu Yi knew that it was prepared for the transformation into a hydraulic mill.

Four rows of houses, wooden sheds just enclosed a courtyard, in the middle of the pre-left a wide yard, in order to facilitate the use of water, Gu Yi let the powerful Mao people use shovels to dig a small pond in the yard with a radius of several zhang, two meters deep.

Then let people use a mallet to smash the bottom of the pond wall as hard as iron little by little, spread a layer of flake pebbles picked up from the river bank, and then extravagantly spread a thick layer of white as snow quartz sand, which is the so-called "dragon chalcedony jade" in this world, and then pave fist-sized pebbles on the quartz sand.

The diversion was to dig a narrow ditch, which was also smashed, and was surrounded by flat stone slabs, which were not dug and directly connected to the river, but made a wooden canal that looked like a seesaw.

When water is needed, the wooden canal is tilted into the river gushing out from the ground, and the water is poured into the stone canal by the force of the river, and flows into the small pond in the courtyard.

In addition, at the request of Gu Yi, under the gable far away from the courtyard, a row of thatched toilets facing the stone wall was also built, and a soil pit was dug behind the thatched toilets, paved with stone slabs, and the old water from the small pond in the courtyard was brought in according to the law for flushing.

On the flat land not far in front of the latrine, a piece of land was opened, not to grow food, but to plant a large area of various wild vegetables and plants designated by Gu Yi dug up from the [Hollow Valley], and several small circles were set up next to the wild vegetable field to raise the baby dolphin cubs that Gu Yi bought and the wild pheasants whose wings were cut off.

When they were busy building, everyone couldn't see anything, and after the completion, everyone was shocked by this beautiful small village of feng shui, and turned around and around in a daze, unable to believe that this was made by themselves, looking at the eyes of the "design master" Gu Yi, as if seeing a ghost.

However, Gu Yi was still a little dissatisfied with the plan to engage in greening in the small village, and then plant a few bushes of wild flowers or something to decorate it, in the final analysis, it was his house attribute attack, and he had a serious house-style complex for a dwelling place, so he instinctively made up such a small village with a completely different style from the village in this world.

When it was named later, Gu Yi originally planned to call it "Peach Blossom Spring", but there was really not a single peach tree in this [Trap Valley], so he could only take a "trapped" full of gangsterism.

Within a few days of Gu Yi leading the people to carry out construction, there were many new arrivals in this [Trap Valley], except for Gu Yi and Bai Min, Rou Servants, and Mao Ren, who were more than 20 people, and the number was still almost 200.

Except for a small number of people who seemed to be more honest and joined Gu Yi and them, most of the newcomers were all under the hands of the short man and the bract, and every time they carried ore and coal in exchange for food, they would stare at the empty village with greedy eyes for a long time.

Seeing their ill-intentioned appearance, Gu Yi didn't bother to deal with it, with the old dwarf, a human-shaped "Tibetan mastiff", he was really not afraid of them making trouble, but he was wary of the recent increase in the number of Lishan people.

The ever-increasing number of people seems to be planning something, which makes Gu Yi slightly uneasy, no matter what conspiracy and tricks Gao Jie and Bud Jaw are conspiring, life always has to pass, Gu Yi can only secretly remind himself to be vigilant, while busy with his own life.

He agreed with Lin Ning that when the [Shuiwatun] monthly market next month, he would deliver "samples" to him for inspection and pricing, and he would have to get some products before then.

Gu Yi formulated the "products" of gold essence, liquor, and halocrystal, the latter needed to be brewed by him personally, and the former was hoarded in this empty river, waiting to be fished, Gu Yi naturally would not let go.

Based on Gu Yi's understanding of the environment of the Hollow Valley and his superficial understanding of the mine, it has been determined that there must be a huge underground river under the Hollow Valley, even an underground lake and an underground sea, and I am afraid that there are also very amazing reserves of gold, silver, copper and iron ore, which can be seen from the abundance of the Hollow River to the terrible placer gold production.

Gold, silver, copper and iron minerals are often associated together, and the metal composition contained in them is very complex, just like gold ore is often accompanied by rare precious metal ores such as ruthenium, rhodium, palladium, osmium, iridium, platinum, etc., but the size of the reserves.

In the surface section of this underground river in the hollow valley, a large amount of placer gold and quartz sand gushed out from the ground through a strong water flow, which indicates that there is a gold ore vein not far from the water outlet, and it is accompanied by quartz ore veins.

With Gu Yi's common sense, he fished in a small river casually, and he found several catties of gold, which is simply unimaginable, although there are factors that accumulate over time, but it also shows how high the grade of this gold vein buried in the ground is... Gu Yi had the impression that in his original world, a few grams of gold could be extracted from a ton of gold ore, which could be regarded as a bonanza.

The gold ore veins in the underground river, with Gu Yi's current ability, of course, can't be used for the time being, but it has been spewed out, so he naturally has to find a way to get it.

After Gu Yi's field exploration, he found that at least 10% of the sediment at the bottom of the [Trap River] is quartz sand, especially a section of the riverbed near the outlet, which is almost full of large pieces of quartz and mica blocks, and even a huge dog's head gold nuggets, but unfortunately the water flow at the outlet is too strong, it can't stand at all, and it is washed away before it goes into the water.

A little further downstream, there is an alluvium of placer gold and quartz sand, and almost the entire bottom of the river is full of thick stuff, as for the ordinary sediment, it has been washed into the small lake in the middle and lower reaches, and the last time Gu Yi and they panned for gold, it was in this section.

It's just that there was no tool to take advantage of last time, just a rough panning in the rich area, and the large particles of placer gold were fished up, which is not the real meaning of gold panning, most of the gold is still mixed in the sediment at the bottom of the river waiting to be excavated, these are the sources of funds for Gu Yi's start in the future.
