The stone knife in Shen Nong's hand is not sharpened by the craftsmen of the Huangqiu tribe, but the predecessor does not know where it came from, this knife is three fists long, one fist wide, the back of the knife is smooth, the blade is slow and blunt, there is no pattern on the knife body, only a cylindrical handle for the user to grasp, rather than saying that this thing is a weapon, Shen Nong feels that it is more like a handicraft.

Reaching out and gently stroking the knife surface, feeling the smooth touch from the skin of the five fingers, he saw that the blade suddenly lit up with a dim white light, and then a warm air flow emanated from the inside of the knife blade, and merged into his body along Shen Nong's five fingers.

Suddenly, Shen Nong felt as if there were countless pairs of dexterous and gentle hands massaging all parts of his body at this moment, which was indescribably comfortable.

The white light came and went quickly, and after about five blinks of an eye, the blade returned to normal, and the airflow that made Shen Nong feel comfortable disappeared in an instant, retracting back into the body of the stone knife.

"Is it time again?" Shen Nong reluctantly wrapped the stone knife with animal skin, and then stuffed it back into its place.

According to the memories left by the predecessor, this stone knife is a kind of witchcraft called 'Wutongtai', which can automatically absorb a kind of qi called 'Qi' in heaven and earth, and then store it for the user to absorb.

Shen Nong didn't know much about 'Qi', and it was mentioned in the memory of his predecessor that after this 'Qi' was absorbed, it could maintain the health of the human body and enhance the spirit of the human body, and there was nothing else.

However, since it was a good thing, Shen Nong naturally had no reason not to absorb it, so he would take the initiative to absorb the 'Qi' stored on the stone knife once a day to ensure that his body could spend his life peacefully in this primitive world without illness and disaster.

After putting the stone knife away again, Shen Nong found that in such a short period of time, Feike and the others had found as many as eight fallen peanuts, and the pods with a lot of soil were a little heavy in their hands, and Feihu held the rhizomes of two fallen peanuts in his left and right hands, and walked over to Shen Nong and smiled: "Wu, I didn't expect that there are a lot of these things growing in this area, and now we don't have enough manpower, so we have to go back to the tribe first, and then bring more people to collect it." ”

"It doesn't need to be that much trouble. Seeing that Feihu was just going to go home with four peanuts, Shen Nong waved his hand directly and said, "You continue to dig first, and I'll make you a tool to ensure that each of you can bring dozens of peanuts back." ”

Dropping this sentence, Shen Nong turned around and walked towards a bush around, he didn't know what his intentions were, and Feihu looked puzzled, but since Wu Du said so, he could only put the falling peanut in his hand back on the ground obediently, and then go back to find the falling peanut in the ground.

Black vine is a very common vine in this forest, this plant is extremely tough, hanging an adult will not break, it is worth mentioning that this vine is only the thickness of fans, the vine body is very long, if you start from the root, a black vine can at least a meter of length of the base.

The tribesmen of the Huangqiu tribe often use this black vine to bind the prey they hunt during hunting, and they can be directly dragged back to the tribe when the time comes.

Shen Nong picked out a black vine from the pile of bushes in front of him, and then began to circle it along the source, and after doing all this, he casually picked up a curved branch from the ground and tied the black vine firmly to both ends of the branch.

"Flying Shell, come over here and try this. Seeing his tools formed, Shen Nong couldn't help but call the flying shell that was working, and after hearing Shen Nong's call, the other party immediately ran over with a falling peanut.

"What's the matter? ”

"Put this on your right shoulder. Lin Chen handed the branch in his hand to the flying shell, and the other party immediately did the same, this branch was about the thickness of a fist, and there was no need to worry about it at all in terms of strength.

Shen Nong took the peanut from the flying shell and wrapped it directly around the black vine at the end of the branch, and he used the black vine to tie a dead knot on the rhizome of the peanut, so that he didn't have to worry about the peanut falling from the black vine halfway through, causing unnecessary food loss.

"Huh?" At this moment, Rao is flying shell also reacted, originally he could only carry about four peanuts in his hand, but after using this simple tool given by Shen Nong, the two ends of the branches could be tied with far more peanuts than four, and the food they brought back to the tribe could also increase several times every time, which undoubtedly improved the efficiency of the collection team.

"It's amazing! I didn't think there could be anything like this, I've never seen it before, Wu, what's the name of this tool?" asked the flying shell, carrying the branch.

"That's the name. Shen Nong was stunned for a moment, and then replied.

"Flat Dan...... Wu, you are so powerful, this tool must have been invented by yourself!" Flying Shell looked at Shen Nong with admiration.

"Well, that's what you want. Shen Nong scratched his head cheekily: "Don't say it, hurry up and dig peanuts, after digging more, everyone's food will be settled." ”

"Yes!" Flying Shell, who got the new tool, was full of energy, carrying a rudimentary version of the flat pole and running to show off to the other members of the collection team, and at the same time did not forget to let them make a flat pole in the same way, so that they could return to the tribe with more fallen peanuts when the time came.

As a new food, the peanuts grown in this area had never been excavated by the tribesmen of the Huangqiu tribe before, so they were very rich in quantity, and after a while, the four of them piled up a pile of peanuts almost a person high under a tree, and the moist soil stuck to the pods of the fallen peanuts, which smoked the air in this area to a strong earthy smell, and it was inevitable that it was a little choking.

"Ahem. Feeling the feeling of rejection coming from his nasal cavity, Shen Nong subconsciously covered his mouth and nose and retreated into the distance, hoping to alleviate the smell.

But at this moment, the flying shell, which had been squatting on the ground and working hard, suddenly looked at Shen Nong and shouted directly: "Don't move!"

The sound was like thunder on the ground, and Shen Nong's ears were buzzing, and he was immediately stunned in place.

"What's wrong?" Shen Nong looked puzzled, and couldn't help but turn his head and look around, hoping to find something different.

"Wu, hurry back and don't go any further. How did Feihu stand up nervously, and said to Shen Nong with some urgency.

Since the other party said so, Shen Nong had no choice but to do so, although he was a noble witch in the Huangqiu tribe, but in the forest, he was nothing, just the most ordinary and weak human being.
