"Oh, it doesn't matter! Those stupid people don't want to go into the water, then we can come by ourselves, I don't believe that so many of us can't find something!"

Don't blame Gu Yi for being nervous, it's just that what Pin Ye said has anything to do with him?

The people in this huge weird world, even if their brains are all beaten into dog brains, they don't have a dime to do with him, for him, it's only right to find a way to get some gold dust as soon as possible, take the opportunity to go out shopping, and leave this ghost place.

Yes, that's right, he wanted to escape!

Ever since he got the old man's bronze [Iron Courtyard Monument], he has already begun to think about this idea!

It's just that he doesn't know anything about this strange world, and he doesn't have the opportunity to leave the [Trap Valley] and [Bluestone Mine] to explore the situation in the surrounding area, Gu Yi doesn't dare to act rashly, so he can only temporarily lie dormant in this [Trap Valley].

In this [Hollow Valley], although he had to fight for life and death, he didn't have to worry about eating and drinking, and now, taking advantage of the fact that the grain in the valley was exhausted, Gu Yi decided to find an opportunity to let Ge Qiao take him out to investigate some information first, and then talk about it, it was better than rashly breaking into this dangerous world with a black eye.

Since there is placer gold in the [Trap River], he doesn't have to worry about the source of funds, Gu Yi clapped his palms with "pop!pop!", and after attracting the attention of the Bai Min, the soft servants, and the Mao people, he gathered them together, and moved out a large number of tools from the iron courtyard, and began to turn the regiments under their command around with great energy, intending to do a big job.

The [Trap River] is no more than a few dozen meters wide at the widest and a few meters deep at the deepest, and only in the section of the underground river outlet is very turbulent, and a large amount of rocky sand and strange-looking underground water creatures are gushing out.

In the middle and rear sections of the [Trap River], as the river surface gradually widens, the water flow naturally calms down, and a small lake is formed in the middle depression of the [Trap Valley], which becomes a paradise for abundant aquatic life.

Although shrimp and crabs are rampant in the river, giant river eels and strange archaeopteryx are everywhere, but after Gu Yi's investigation, he did not find any too dangerous creatures, as long as he was careful to prevent the kind of bigmouth with exoskeleton rushing over and biting people when he entered the water, there was basically no great danger.

While Bai Min, Rou Servant and Mao were busy preparing the utensils that Gu Yi needed, Gu Yi dived into the river several times and found the alluvial zone of the [Trap River], this section of the river was relatively gentle, and the sand and gravel gushing out of the underground river were accumulated in this section of the riverbed, which was exactly the location he was looking for.

The sand and gravel that is gushing out of the underground river are generally not too large, and the heavier stones settle near the outlet.

The smaller particles are washed down by the turbulent current, and the lighter sand is washed directly into the lake, while the heavier placer gold settles down on the riverbed in front of the lake, and is washed by the water of the [Hollow River] day after day.

Gu Yi, who dived into the bottom of the river in the alluvial zone, took out a handful of sediment and looked at it, and almost choked to death in the water!

He just dug it out at the bottom of the river, and the mud and sand that he grabbed out were golden, how rich is the gold mine in this underground river?

Gu Yi was very suspicious that there was a thick layer of placer gold under the entire [Trap River], but unfortunately, under the current conditions, it was impossible to mine the placer gold deposits under the entire [Trap River], and only a little bit could be found in the rich area.

Although he knew that the world of Lu Dao was no longer his original space, and gold was just grit that he couldn't eat or drink, Gu Yi couldn't help but speed up his heartbeat, his blood was trembling, and his eyes were full of greedy golden light, and he felt that it was golden when he looked at the flowing river.

Ge Qiao's kid called the placer gold "gold essence", which made Gu Yi very strange, and only after asking did he know that the people in this world called "copper" "gold", and gold, a rare and difficult to mine precious metal, was called "gold essence" by them, which means "gold essence".

No wonder he heard them shouting "golden cakes" at every turn, which made Gu Yi think that the gold reserves in this world were very huge, and they were enough to be directly minted into palm-sized gold cakes to use as currency.

And their so-called "dragon chalcedony jade", in fact, is associated with the gold ore quartz ore, or mica ore, most of them are milky white, Gu Yi found some in the upper reaches of the placer gold rich area, the small one can have the size of a finger, the big one can have the size of a fist, it is very beautiful to be washed by the river, but unfortunately all of them are buried in the silt at the bottom of the river and do not see the light of day.

In order to facilitate the excavation of the sediment mixed with placer gold, Gu Yi selected a section of the narrowest riverbed not far from the upstream of the placer alluvial zone, and then took the Baimin, barbarians, and Maomen on both sides of the riverbank to manually dig two drainage canals, transforming this section of the riverbed into a buffer zone in the shape of "Zhong".

Even in order to slow down the flow of the river, the Mao people, who are infinitely powerful, carried a piece of boulders weighing thousands of catties into the river, and built a dam in the river to block the river water, so that the river level of the placer alluvial zone dropped several meters at once, and people stood in it, and the water level was only up to the waist.

Whether it is the hairy people, the barbarians, or the white people, now they are all strong men who pull out thousands of pounds, carrying hundreds of thousands of pounds of boulders and logs can also walk like flying, whether it is digging drainage canals, or logging into the riverbed to fill rocks to build dams, one by one like humanoid excavators and forklifts, the transformation of a large amount of projects, only took half a day to complete.

They tossed indiscriminately on the river, and the most direct situation was to stir up the river water, and all the water tribes in the river were considered to have fallen into bad luck, and they fled in panic, and were captured by Gu Yi and the white people, and piled up on the river bank to prepare for a meal.

The most interesting thing is that after having the stone dam of the barrage, Gu Yi no longer has to bother to catch fish, shrimp, crabs and mussels, he found a long thick vine, woven into a huge rattan net, tied to the big trees on both sides of the river bank at both ends, buried at the bottom of the river with stones, and then tied a few small dumb woven kudzu grass bags on the rattan net, and when he was hungry in the future, he went directly to the rattan net to untie a kudzu grass bag, which was full of fish, shrimp, crabs and eels.

Gu Yi simply arranged two hairy people to carry the cauldron to dig out a large amount of sediment from the gold alluvial belt and transport it to the soft servants and white people who are responsible for gold panning downstream of the alluvial belt.

In this way, a large amount of sediment will be carried downstream by the river, so as not to cover the unexcavated gold silt layer again, which will bring trouble to the subsequent gold panning work.
