Since Shen Nong used a bison raised by the tribe to confirm that there would be no problem with the water in the ditch after it was cooked, he allowed the people of the Huangqiu tribe to use the water in the ditch, but the use is for use, and the person who scoops the water must be prepared for safety, must wear animal skin gloves to prevent the water from coming into direct contact with the body, and must be cooked in a bone pot before use.

In order to ensure absolute safety, and in order to prevent any clansmen from suddenly turning into purple balls, Shen Nong even did not hesitate to sacrifice the bone pot that had been used to cook meat in the Huangqiu tribe, and the clansmen of the Huangqiu tribe could no longer taste the taste of stewed meat for a short time.

All the leucoccus algae that were flooded and grown on the shore of Baize this time were destroyed, and I don't know how many parasitic spores were mixed with the water of Baize Lake, and then floated in Baize, which was a very terrifying thing.

Because just recently, the people of the Huangqiu tribe found that there were fewer and fewer fish in the waters near Bai Ze, and from time to time there would be corpses of unknown creatures wrapped in purple tentacles in the ditch floating in from the side of the Bai Ze inlet, which further verified that Shen Nong's worries were correct, and there were really a large number of parasitic spores in the Bai Ze water.

After seeing this situation, the people of the Huangqiu tribe, who were originally a little careless when taking water, immediately became strict, and everyone followed the rules required by Shen Nong, such as wearing animal skin gloves, holding a long-handled wooden scoop, and boiling before use.

In this way, although there are many parasitic spores in the water in the ditch, the people of Huangqiu have not been in any danger, and everything is very safe.

"Witch! There's a lot of strange stuff in the ditch. ”

Early this morning, a peck ran to the outside of the entrance of the small cave and shouted at Shen Nong, who was still asleep in the cave.

Shen Nong was originally a person who slept deeply, but since he came to the Huangqiu tribe, the degree of sleep has become shallower and shallower, almost as soon as there is any wind and grass, he will immediately wake up from his sleep, which he would never dare to imagine before.

"What's going on?" Shen Nong asked, getting up from the grass bed.

"There's a lot of stuff floating in the ditch, and they look like water. Peck said hurriedly.

"Oh......" Shen Nong rubbed his eyes indifferently, then walked out of the small cave and said, "Take me to see." ”

At this time, many Huangqiu people had gathered near the ditch, and they were all looking curiously into the ditch, and they were also whispering to each other.

When Shen Nong followed the pecking bone, everyone immediately gave way for Shen Nong to go to the ditch to check.

Shen Nong took a closer look into the ditch, and saw that the ditch was turbid and white, the waves were moving slightly, and the water surface was rippling.

The turbid white water is also a characteristic of Bai Ze, so at a glance, Shen Nong didn't find anything wrong, but after he took a closer look, he saw something weird.

I saw that in the turbid white flowing water, there seemed to be a semicircular thing swinging and fluttering with the current. Shen Nong suddenly came to his senses, and hurriedly widened his eyes, trying to see what those things were, and after observing them in place for a while, Shen Nong finally got the answer.

Jellyfish, the things that float in the water are clumps of jellyfish that are almost transparent in color.

Shen Nong could even see long strips of tentacles under their semicircular bodies, drifting with the current.

"How could this kind of thing appear?" Shen Nong couldn't help frowning and wondering, there are really more and more strange things happening in Bai Zeli, not long ago, an extremely dangerous leukococcus algae appeared, and now there is this kind of transparent jellyfish with unknown danger, the situation is really incomprehensible.

"Wu, do you want to fish it up and have a look?" asked the.

"It's better not to, now we don't know if these things are dangerous. Shen Nong shook his head.

At this time, the ditch was filled with a large number of transparent jellyfish, and they squeezed their sacs in the ditch, but the strange thing is that after a short time, these transparent jellyfish quickly left, and in the blink of an eye, there was not a single transparent jellyfish in the ditch, and it returned to its previous normal state.

"That's it?" Shen Nong was stunned, he hadn't figured out what the hell was going on.

However, since the transparent jellyfish have disappeared, Shen Nong will no longer delve into it, anyway, there are enough mysterious events in this world, and it is impossible for him to investigate them one by one.

Since it is rare to get up so early today, then start working in advance, with this idea, Shen Nong immediately called Cang, Pan, and Xuanjia.

"Witch. ”

"I've made what you've made ready, right?" Shen Nong asked.

"Well, the door is ready, but the trebuchet isn't yet. Kura nodded.

"Let's install the door first, so that by the way, the door can be carved a little bigger, so that the trebuchet can easily enter and exit later. Shen Nong said.

"Yes. ”

Under the command of the three Cangs, the Huangqiu tribe did not take the slaves under their management to dig ditches outside the southern wall, but repaired them above the southern wall.

A large number of eel slaves climbed the wall, chopped the branches from the trunks with stone knives in hand, and then sawed the treetops directly above the doorway with bone saws.

Another group of eel slaves came from a distance carrying a wooden raft made of eight log pillars connected side by side.

The wooden raft is five meters long, three meters high, and half a meter thick, and the bottom of the wooden row is all cut into a conical tip, so that when it is lowered, it will be firmly inserted into the soil to achieve a stable effect.

You can see that a large hole has been carved out of the same place in the body of the eight log columns, and then a long log crosses all the log columns, giving the effect of connecting all eight log columns side by side.

Of course, the black rattan rope is also indispensable, and the binding of the black rattan rope can make the eight log columns closer and more free of gaps.

This wooden row is the gate made by Shen Nong Rangcang, but this door is very different from ordinary doors, first of all, it is not open, nor push-pull, nor sliding, but lifting.

On the left and right sides of the wooden row, there is a round hole for tying the black rattan rope, when the two black rattan ropes are tied to the two round holes, if you can have enough force, you can lift the wooden row and pull it to a high place.

Is there such a force in the Huangqiu tribe?

Absolutely!

As long as a super-large pulley block is fixed above the door opening, and then the oversized pulley block and the wooden row are connected together with a black rattan rope, the Huangqiu people standing on the fence can lift the wooden raft from the ground to a high place by turning the bar handle of the oversized pulley.

When the obstructive branches on the wall were almost cleared, and the treetops were cut down, Shen Nong nodded and said, "Cang, take someone up to assemble the oversized pulley set." ”

"Yes. ”

Under the leadership of Cang, soon the Huangqiu tribesmen, who were familiar with the structural assembly of the pulley block, climbed the wall with him, and they all carried the parts of the pulley block on their backs, and they could start assembling it immediately after reaching the top of the wall.

Only the knowledge that is shared is the most powerful, everyone will have different thoughts and opinions on the same thing, maybe a huge change comes from the opinion of an ordinary person, after Shen Nong taught some of the things he knew to the four of Cang, he did not let them hide their secrets, but let them teach as many Huangqiu people as possible.

Only when everyone makes progress together can the Huangqiu tribe develop faster.

Some of the Huangqiu people tied the wooden rafts with black rattan ropes below, and as soon as the oversized pulley set above the fence was assembled, they would immediately send the black rattan rope up and hand it over to the warehouse to tie it to the oversized pulley.

The assembly speed of Cang and the others was not slow, and soon a complete oversized pulley set was assembled above the wall, and Cang also successfully took the black rattan rope from a clansman and tied it to the pulley.

"Alright, pull it up and take a look. Cang said.

Immediately, two people from the Huangqiu tribe held the levers on both sides of the oversized pulley set and turned them.

Click, click, click!

There was a violent sound of wood turning in the oversized pulley group in an instant, and then the black rattan rope rolled up and became shorter and shorter, so that the wooden row below could no longer remain in place, and was directly lifted away from the place by the pull of the super-large pulley block and rose into the air.

"It's a success!" Seeing this scene, the people of the Huangqiu tribe couldn't help but say excitedly.

Only Shen Nong was still standing in place relatively calmly, after all, for him who was used to seeing cars, planes, trains, and various electronic products, a lifting door that was activated by man was really not something that could make him feel excited.

If the three projects of the second district, the water transmission system network, and the trebuchet can also be completed, perhaps he can feel some excitement and joy, after all, this is a plan he has been thinking about for a long time.

The wooden row was pulled to a position about half a meter above the doorway and stopped, and the bin stretched an iron pickaxe handle into the oversized pulley block, stuck in the tooth edge of a gear, just stuck the rotation of this gear, and because of this, the other gears in the entire oversized pulley block could not move.

In this way, the wooden raft can be completely fixed above the door opening, so that the people of the Huangqiu tribe who enter and exit from the door hole will not die because of the sudden fall of the wooden raft.

In this way, there is a regular gate in the Huangqiu tribe, and there is no need to move a big stone around every day to block the doorway.

After all this, the group went to the south wall again and began the construction of the second district.

Now that there is already a wall in the second district, as long as the remaining three sides are finished, then you can start to build wooden houses and officially recruit the four scattered departments, and I am still quite looking forward to this Shen Nong.

After all, once the scattered tribe joins, the total number of people in the Huangqiu tribe can skyrocket, and once the number is large, it will naturally be able to do more things.

"Wu, last time you said that you planned to go to the Red Valley Tribe to trade that thing with them, after so long, will we still go?"

"It's not urgent, we don't really need linen at the moment, and it's not too late to delay it for a while. Shen Nong said casually.

However, this time, Chi suddenly ran over to ask him this question, obviously not casually, and saw Chi standing in place with some hesitation, as if he had something to say.

"What's wrong?" asked Shen Nong puzzled.
