Just when Shen Nong was concentrating on designing the equipment structure drawing, the warehouse had already led people to start paving the water conveyance project.

First of all, this is definitely the largest project of the Huangqiu tribe so far, just the distance from the Huangqiu tribe to the Huatian tribe on the way, it is enough to keep them busy for a long time, the intestinal tube must not be placed on the ground at that time, and the use of it still has to be buried in the ground and covered by the soil.

Originally, Shen Nong planned to use the ditch as the terminal water conveyance, but then there was a sudden occurrence of leukoccoccus and parasitic spores, which led to the fact that all the water in the ditch needs to be boiled before it can be used normally.

In this way, the ditch is a terminal water source that is more troublesome, but there is no other choice within the Huangqiu tribe at present, because they really don't have many water sources.

But Bai Ze is not a dead lake, its water circulation ability is there, I believe that if you wait for a while, those parasitic spores floating in Bai Ze should be able to be replaced by the water cycle.

In order to detect this in time, Shen Nong also had people dig a large pond halfway from the ditch to the Huangqiu tribe, fill it into a pond, and then insert two wooden planks full of finger-sized planks at the inlet and outlet of the pond, which can have the effect of filtering the water and preventing the creatures in the pond from escaping from the pond.

This pond Shen Nong intends to use as a fish pond, so that when the time comes, fish can be raised in it, and these fish can be used to test whether the water flowing from the direction of Bai Ze contains parasitic spores.

If there is, the fish will appear to be wrapped in purple tentacles and die.

If not, the fish will live unharmed.

In this way, the Huangqiu tribe can have a clear understanding of the safety of water sources.

The source of fish is still very easy, and there are many fish in the coastal waters of Shirasawa.

In addition to doing this, the construction of the third and fourth districts was also incorporated into the preparation list, and Shen Nong finally felt what it means to be powerless and not have enough population.

However, there is no way, the population problem is originally a defect of the Huangqiu tribe, and at present, it can only rely on slowly recruiting scattered people to increase the population.

And when everything stabilized, Shen Nong also thought of what he had promised at the beginning, saying that he would take him to the Honggu tribe when he was free.

Of course, Shen Nong didn't plan to go to the Honggu tribe just to let Chi Neng tell the father and mother that the mother was pregnant, he specifically wanted to trade linen fabrics from the Honggu tribe, you must know that this thing feels much more comfortable to wear on the body than animal skin clothes, and it is easy to clean and replace.

And once the autumn is followed by winter, when the weather waterfalls to cool down, the people of Huangqiu must wear a little thicker to survive this cold season, in the previous cold season, more or less people will be frozen to death, which is inevitable.

But now that Shen Nong has come to the Huangqiu tribe, he has to do his best to avoid freezing to death again.

Linen fabric is a good way to keep you warm.

If you make a large jacket with a double layer of linen fabric, and then fill the double layer with dried animal hair, you can get a thick jacket weighing seven or eight pounds, which can make people feel warm when worn.

In addition, the stoves and chimneys set up in the wooden houses of the Huangqiu tribe at the beginning, when the winter comes, the wooden houses are closed with the doors, and the stoves inside are burned to generate heat, and I believe that it will be very warm to stay in the wooden houses.

Therefore, going to the Honggu tribe to trade linen fabrics has become something that Shen Nong must do before the cold season comes.

After explaining the affairs of the tribe to Xiong Yao and Cang, Shen Nong took Chi, Chi, Shaotiannu and Shao Hao, as well as four ordinary clansmen, to push into two carts, carry two devil frogs and prepare to hit the road.

This time he went to the Honggu tribe to trade, and Shen Nong specially brought the special products of the Huangqiu tribe, pottery and star anise, I believe that with these two things, he should be able to trade linen fabrics from the Honggu tribe.

In order to prevent accidents on the road, Shen Nong also deliberately brought four spear launchers, including the one he made three times in a row.

If only two board trucks were used to carry them, these things would definitely not be able to fit, and this is when Brother Toad and Brother Toad come in handy, their backs are enough to put a lot of things.

......

The ancestral land of the Honggu tribe is located in the south, and in terms of distance, it is even farther than the Cangtao tribe, and Shen Nong and the others need to walk for a day or two to reach the Honggu tribe.

In the past, the ten-part conference was held in the Honggu tribe, so Chi and they knew the way to the Honggu tribe, and Chi knew Zhu Chun at that ten-part conference, but the two of them were not together that time.

Because there are too many trees in the forest and the growth is too dense, Shen Nong and the others did not choose to walk in the forest, but went south along the bank of Baize, where the trees are scarce and the road is spacious, which is very suitable for the passage of board vehicles.

Since the leukococcus was removed, the entire white sea has returned to normal, and the original water level has risen again, which causes everyone to no longer be too close when passing by, otherwise they may be swallowed by some monster poking out of the water at any time, and the corpse will not be seen.

A few months ago, Xiong Yao brought a few Huangqiu people to the shore of Baize to fetch water, and Shen Nong still can't forget the three Huangqiu people who were eaten by Canglong, because the impression was too deep.

"Quack!" Brother Toad and Brother Toad looked at Bai Ze Lake curiously, if it wasn't for Shen Nong to control them, I'm afraid that these two devil frogs would have jumped into Bai Ze with the goods they were carrying to play, frogs still like water after all.

Normally, Shen Nong also forbade Brother Toad and Brother Toad to enter Bai Ze, because their current body size is still too small, and after entering Bai Ze, for those behemoths living under Bai Ze's water, they are just two lumps of meat, which are food.

Shen Nong also counted on Brother Toad and Brother Toad to be able to go out and bring back a large number of frog eggs for themselves when they grew up, and bring a group of amphibious mounts to the Huangqiu tribe, they must not die halfway, otherwise Shen Nong's dream of being a water army would be ruined.

Therefore, before Brother Toad and Brother Toad grow up to be as large as their mother's, Shen Nong will not allow them to enter the water, because it is to send them to death, and there is no meaning. In this regard, Brother Toad and Brother Toad can only look at the water and sigh, who said that they were controlled by Shen Nong.

If by the time Brother Toad and Brother Toad both grow to a huge size of more than ten meters, with the combat power of the two of them, the Huangqiu tribe might still be able to control this large area of water near the shore of Bai Ze.
