After Bangcang and Jiajia solved the problem of the wheels of the board car, Shen Nong immediately began to examine the finished tools made by Pan and Beibang. In the past day, the two of them have been efficient enough, and have successfully produced three bone shovels, two stone hoes, and four stone pickaxes.

Among them, the combination of the hoe and the end of the pickaxe and the handle is embedded, so these two tools can use the stone as the material, and the shovel needs to use the rope to tie the end and the handle tightly together. When the two of them confessed, they specifically told them to change the material for making shovels from stone to bone, so that it would be more convenient for the tribesmen to use.

Picking up a stone hoe made by the two of them from the ground, Shen Nong carefully checked it, only to see that the head of this stone hoe is flat and wide, the shape is rectangular, and the hoe mouth is thin and sharp, which can make it easier for the user to swing the hoe into the soil.

At the end of the head of this hoe, there is a round hole the thickness of an adult's wrist, and a wooden stick of the same diameter is directly inserted into this round hole, which is firmly attached to the round hole, and the wooden stick is also stuck in the round hole, and no matter how hard it is, it cannot be pulled out.

Shen Nong wielded this hoe and chiseled a few times on the ground, and nodded with satisfaction, overall this stone hoe is still good, although the shape is very rough, and the handle is also a little grinding, but it is better than a strong and durable, and the action of chiseling up the soil is unusually smooth.

Putting the stone hoe back in place, Shen Nong tried both the bone shovel and the stone pickaxe by the way, and the result made him very satisfied, these three tools are now more than enough to start the project.

"Yes, just make it according to the current style, make ten of each tool, and when you are ready, go to me above. Shen Nong said.

The small cave he lived in was just above the big one, so there was nothing wrong with saying it was above.

After explaining to the four craftsmen, Shen Nong walked out of the big cave, because there were still a large number of prey corpses in the foothills of the Black Mountain, except for Chi and Shi Li, the other members of the hunting team and some male clansmen all left the tribe again and entered the forest and rushed towards the direction of Black Mountain.

As long as they brought back the carcasses of the prey, the hunting party would no longer have to go out hunting for a while, and could stay in the tribe to accompany their women and children.

With the departure of the hunting team, Chi was sent by his father and mother to recuperate, Feihuo went out to collect food, and Peck Bone also followed the hunting team to help, Shen Nong suddenly became idle, the people he knew and named were either busy, or they were not in the tribe, and there was no one to talk to him at the moment, in this primitive tribe without any entertainment facilities, Shen Nong naturally felt bored.

When you are bored, you naturally have to quickly find something interesting to do and make yourself chatty, but Shen Nong walked around the tribe and found that everyone was either helping the tribesmen make animal skin skirts and animal skin clothes, or they were handling food, skinning the prey corpses brought back by the hunting team one by one, washing blood, removing impurities, and finally taking all the meat that could be eaten and putting it on the rocks to dry.

Everyone in the clan seemed to be very busy, everyone had their own work to do, and only Shen Nong was idle and idle.

"Well, if only he hadn't blessed him, at least he would still be able to talk to me now. Shen Nong sat on a half-human-high rock casually, looked at the sky helplessly and said.

Shen Nong didn't notice that when he said this, Xiong Yao didn't know when he appeared behind him, and he listened to this sentence in his heart.

Xiong Yao looked at Shen Nong thoughtfully, and then involuntarily showed a strange smile on his face, and then quickly turned around and left.

......

Three days later.

The sky had just dawned, and the grass outside the big cave was full of people from the Huangqiu tribe, each of whom was holding a tool made by Pan and Beibang himself, and their faces looked very happy.

Next to the crowd, there were also ten wooden carts parked, and there were ten clansmen standing next to the carts, responsible for pushing the ten carts forward.

Shen Nong stood at the front of the crowd, on his left hand stood Chi Hao, who had returned to normal by drinking the blood of the fierce beast, and on his right hand stood Shao Hao, who did not need to go out hunting, and the three of them all looked at those clansmen with serious faces, and the atmosphere was very solemn.

"This operation is very dangerous, we have to dig a ditch on the bank of Bai Ze to go straight to our tribe, this is a big project, it is also a dangerous project, each of you is likely to die in this operation, but once we complete this project, then the tribe will no longer have to send people out to Bai Ze to get water, the water will continue to flow to our tribe, this is a good thing for the tribe!" Shen Nong said loudly.

Those clansmen with tools in their hands were all looking at Shen Nong and listening very seriously, there was a danger about this operation, Shen Nong had already told them two days ago, and now the clansmen standing on the grass all took the initiative to ask to join this operation, they had already put life and death aside at the moment of decision, as long as it was beneficial to the tribe, they were willing to give their lives to do it.

"Wu, let's go, we're all ready!" said one of the clansmen at the front of the line.

The other clansmen were like firecrackers lit in the line of fire, and they all held up their tools and shouted, "Let's go, let's go!"

Shen Nong nodded, grabbed the hoe in his hand and walked towards the forest, Chi and Shaohao followed behind him, the clansmen followed closely behind, and a group of people quickly disappeared into the forest.

Xiong Yao stood at the entrance of the big cave with several old men, looking at the direction of the clansmen leaving with some concern, and an old man asked with some hesitation, "Let them go like this, can we really dig up that ...... Ditch?"

Another old man said with the same concern: "Wu has never mentioned any ditches before, and I don't know how he knew about this thing, and Bai Ze is so dangerous, the water monsters in the lake will eat anyone who appears near the lake." ”

Regarding the words of the two old men, Xiong Yi just shook his head and said: "We just need to believe in Wu, his idea is also for the good of the tribe, if Bai Ze's water can really flow to our tribe, then there will be fewer deaths in the future, and ......"

Xiong Yao's words suddenly paused: "In a while, the Ten Ministries Conference will begin, and I plan to let the young people of the tribe bring Wu over to participate in it at that time, what do you think?"

"The Ten Conferences?" an old man was stunned: "But the Ten Conferences are not always young people...... Oh, chief, do you want to!"

The old man's face was shocked, obviously thinking of something terrible.

Xiong Yao nodded seriously: "Yes, that's what I planned." ”

"But would he be willing?" asked an old man hesitantly.

"I heard Wu say that he was bored by himself, I think he would be willing, now we don't have to worry about so much, when the young people take him over, I think Wu will make his own choice. Xiong said lightly.

Since the chiefs had said so, the old men were not ready to say anything more, so they nodded their heads in agreement. Shen Nong, who was out, didn't know, because because of what he said inadvertently at that time, Xiong Yao made a very wonderful decision for him.

......

The location of the Huangqiu tribe was still very close to Bai Ze, and after Shen Nong and the others walked a thousand steps, they had already seen the pale white lake of Bai Ze, as well as the surface of the lake that could not be seen.

Today's situation is quite special, there are no wild beasts drinking by the lake, so it seems that the whole Bai Ze is particularly quiet, the lake surface is rippling in circles of beautiful ripples because of the breeze, but everyone knows that under this rippling lake, there are countless dangers.

"Let's all be quiet, dig a pit here, and then throw all the dirt on the shore and build a wall of dirt, so that you can prevent a monster from jumping out from under the lake and eating our people. Shen Nong casually pointed to a piece of land under his feet and said.

Immediately, people with stone pickaxes and stone hoes came and dug a pit in the ground very hard, and the soil dug out of the pit was immediately picked up by the clansmen with bone shovels and put on the carts, and then the people pushing the carts pushed the soil to the lake.

In this process, a tall and thick earthen wall was soon erected around the lake, covering the edge of Lake Shirasawa in this area. With the protection of this wall, the clansmen can start to break ground behind the earthen wall with impunity.

"Start digging from the base of the wall, dig in a straight line towards the forest, don't dig too long, let's go about five paces, as long as we stay away from the shore, we can move much safer in the future. Shen Nong said.

Under his command, everyone soon began to work, everyone was using tools for the first time, so they all felt special novelty, and the work was also very exciting. Soon dug a five-step deep ditch from the shore, but the depth of this ditch is currently only half a person high, which is definitely not up to Shen Nong's requirements, in Shen Nong's opinion, the ditch in his mind must be two meters deep to be qualified.

However, there is no need to worry about this matter, as the so-called firewood gathering is high, I believe that it will not be long before the people of the Huangqiu tribe will dig a qualified ditch of sufficient scale to send Bai Ze water to the Huangqiu tribe.
