This time, Shen Nong brought out a total of two silver-crowned dragon kingfish's backbone cartilage, and in view of the length of the backbone cartilage, it is the most perfect match for two people to control one together, so after Shen Nong told Chi and Shaohao how to use the backbone cartilage, he took the bear sickle to the other side of the giant tree.

Because the trunk of this giant tree is relatively thick, the sawing efficiency of only one side is very slow, if you can cut on both sides at the same time, and then when both sides are sawing to the center of the trunk, you can push hard in one direction, so that the big tree can be quickly cut down.

Shen Nong handed one end of the backbone cartilage to Xiong Sickle, and he took the other end to the tree not far away, and the two of them brought the jagged edge of the backbone cartilage close to the tree trunk, and directly sawed each other left and right.

After a while, the surface of the trunk was sawed out of a white hole more than a meter long, and there were a lot of wood chips scattered on the ground, I believe that at this speed, everyone should be able to sawn down this big tree in half an hour.

"Wu, how are we going to get this tree back to the tribe?" asked Xiong Sickle, embarrassed.

You must know that even if he is a second-level warrior, he can't drag such a big tree.

"I have my own way, so you don't have to worry, now I'll see this tree down. Shen Nong replied indifferently.

After a while, the backbone cartilage of Shen Nong and Xiong and Shao Hao were getting closer and closer, and seeing that the big tree was about to be sawed off, Shen Nong hurriedly shouted and asked them to stop the movements in their hands.

Xiong Yao and the three of them all looked at Shen Nong with puzzled eyes, not knowing why he suddenly let himself and the others stop, seeing that there was only a trace of this big tree left to be sawed off.

"You two come here, come to my side. Shen Nong commanded.

Chi and Shao Hao took out the backbone cartilage from the tree, and then walked to Shen Nong's side.

Anyone who has ever been involved in logging knows that it is not necessary to cut off the entire tree when cutting down a tree, as this will cause the tree to fall in a random and uncontrolled direction, which can easily injure the logger.

So when cutting wood, you only need to sawn off most of the tree, and then leave a trace of the tree connection, and wait for the lumberjack to push down hard to determine where the tree will fall in the end.

After Shao Hao and Chi came to his side, Shen Nong pointed to an area on the tree and said, "Wait a minute, let's hit this place hard together, and let this tree fall to that side, do you know?"

"Uh-huh. The three of them nodded their heads in understanding.

"Okay, I said we'll hit each other together. Shen Nong said with a serious expression: "Begin!"

The four of them gathered all their strength and slammed directly into the trunk of the tree.

Bang, bang, bang!

There were four muffled sounds, and under the combination of second-level warriors, first-level warriors and quasi-warriors, the last trace of connection on the trunk could not be directly supported, and it broke in an instant, only to see the big tree surrounded by three people clicking, and the momentum could not stop falling forward.

Rumble!

When the big tree fell to the ground, the dust was flying, the grass was full of sand, and a sapling only one person tall was directly crushed into two pieces on the spot, which was very miserable.

"We're going to cut down a few more, it's not enough just like that. Shen Nong said, and then took Xiong and the three of them to look for suitable trees nearby.

Shen Nong and his party cut down indiscriminately in the forest, naturally panicked a lot of beasts and poisonous insects, including the birds perched on the treetops, the forest in this area was suddenly turned upside down and deafening by Shen Nong and his party, many wild beasts immediately turned around and ran away after being frightened, and there were also some wild beasts that wanted to attack Shen Nong and others, but in the end they all became a corpse and became the food of the Huangqiu tribe.

Shen Nong, Shao Hao, and Chi plus a bear sickle, this combination basically has no beast that can be their opponent except after encountering a pure-blooded fierce beast.

Rumble!

When the thirteenth giant tree that met Shen Nong's standards fell, Shen Nong reached out and wiped the sweat from his forehead, looked up at the sun that had risen to noon, and said, "Let's get here first today." ”

In the course of the day, from noon to afternoon, the weather is the hottest, and the summer heat has come, Shen Nong estimates that the current maximum temperature must be above 39 degrees, and heat stroke will inevitably occur, which is really not suitable for work.

"What about the trees?" asked Chi Re, blushing

"Just put it here first, no one but us will need this anyway, and someone can't steal something this big. Shen Nong said indifferently.

With a tree like this that is more than 20 steps long, Shen Nong believes that no one but himself should have a way to transport it away, after all, a tree like this weighs at least about 1,000 catties. In this day and age, if someone wants to move it, the difficulty factor is really similar to that of heaven.

After memorizing the location of the thirteen giant trees, Shen Nong and his party returned to the Huangqiu tribe.

......

In the next few days, the entire Huangqiu tribe was busy digging ravines and logging trees, and according to Shen Nong's predictions, it seemed that at least fifteen giant trees would need to be inserted into the corresponding ravines in each direction to fill one side.

In other words, if you want to fill the ravines in all three directions and finally form a wall that surrounds the north, east and south sides of the Huangqiu tribe, you will need at least 45 big trees. It would take at least three or four days to accumulate this amount.

At present, the insect tide that Luo Man warned before leaving may come at any time, Shen Nong couldn't help but feel a special urgency in his heart, for the current Huangqiu tribe, if the wall can be built before the insect tide comes, then the survival rate of the Huangqiu tribe will be greatly improved.

"Ahem!" a Huangqiu tribesman climbed up from under the ravine with a bone shovel in his hand, his face looked very pale, and the dark circles around his eyes were extremely heavy, and he looked like he hadn't slept for several days and was very depressed.

"What's wrong with you?" asked Cang, who was standing next to the ravine, immediately walked over and asked with concern.

"Dizziness...... Headache...... I don't have the strength to ......," the clansman said truthfully.

Cang nodded understandingly, he knew that the clansmen had been too tired recently, and they had to go down to the ravines every day to dig the soil, not to mention, and when they were idle, they had to be taken by Shen Nong to the forest to help with logging, which was quite busy.

Under this kind of high-intensity physical work, it is inevitable that some clansmen will feel unwell, which Shen Nong has already explained to Cang and others in charge of commanding before, if they find that some clansmen are not feeling well, they will immediately have to go back to rest and can no longer work.

After all, the project is dead, the person is alive, the project can be done at any time, but if the person dies, then it will never be seen again.

Cang said directly: "Then you go back to rest first, don't work." ”

The clansman nodded weakly, returned the bone shovel in his hand to the warehouse, and walked straight to the wooden house where he lived.

Cang suddenly looked back at the person's back a little strangely, and muttered very curiously: "When he gave me the bone shovel just now, why did I suddenly feel cold and cold, as if it was winter, it's really strange." ”

didn't think too much about it, and immediately devoted himself to his work.
