Strictly speaking, the seeds of potatoes are not the potatoes themselves. Potatoes belong to the Solanaceae family, and their seeds are similar to tomatoes and eggplants, and they are fine particles, and there are thousands of seeds per gram, so they are not potatoes themselves.

The reason why the potato itself is generally used for propagation, when the tuber of the potato is cut into small pieces for planting, each small piece should have a concave eye on it, and there are small buds in it after staying up all night, which is the bud primordium from a biological point of view. The small buds inside can be produced into new plant individuals, and the vigorous auxin in it can not only promote the growth and development of the plant, but also improve the disease resistance of the plant.

Therefore, in general, farmers reproduce through potato tubers, that is, asexual reproduction. Only its seeds, its offspring have strong variability, so it is often used for genetic breeding, and the adaptability of seeds is also very strong, and it is suitable for sowing seeds in the environment of primitive societies.

From this, it can be concluded that the old man who gave Ye Feng seeds at the beginning was also a seed breeder in addition to selling vegetables, so why did he come to sell vegetables bitterly, this is not enough for outsiders to know.

Of course, Ye Feng didn't know anything about this. He wants to protect all of this, knowing that the yield of potatoes is very high, and it has become the world's five major crops along with wheat, corn, rice, and sorghum, and if potatoes are formed to adapt to this environment, it will also be of great benefit to the tribe.

He called the people just now, and put a fence on the potato field, and put thorns with spikes around the fence, and specially instructed people to take care of the field, and sent people to keep an eye on the attacks of pests and herbivores. To put it mildly, if it weren't for the absence of an army, uninformed people would have thought that there was a nuclear arsenal hidden here.

Of course, it is impossible for primitive people to know about nuclear weapons, and the "nuclear weapons" in their eyes are bronze weapons. When they were told by Ye Feng that the crops in this field were no less important than those of bronze and rice, they began to become cautious, staring around like alert warriors, for fear that something would destroy these crops.

Seeing the appearance of these people, Ye Feng also put his mind at ease, and became a shopkeeper again.

……

On this day, Gray, the chief of the Rock Tribe, personally came to escort the goods traded to the Star and Moon Tribe. Due to the large number of goods, Gray couldn't put his mind at ease, so he delivered the goods himself. Of course, there is a more important point, take a look at the unfinished walls of the Xingyue Tribe.

"Is that wall that you're talking about really that high?" Gray asked as he turned to the man next to him.

If there is a person from the Star-Moon tribe around, he will definitely be recognized—the person who delivers food to the Crescent tribe.

Hearing Gray's question, he was immediately excited, and said, "My great chief, why don't you believe me, that wall of theirs is so high that you can't see the sky when you stand below!" ”

Gray's face was still in disbelief, and he warned, "If even your dearest chief lies, see how I don't skin your boy!" ”

The man looked aggrieved and said, "It's true, why don't you believe me!" ”

When Gray really saw the walls of the July Tribe, he felt that you were right, although it was not as big as the man said, it was really tall.

Although the city wall was not completed, it still had an overwhelming and impregnable momentum. Gray's heart trembled violently, suppressing the excitement in his heart, Gray walked through the gate of the city wall, at the city gate, Ye Feng had been waiting for a long time.

"Yo, our Great Chief Gray is here! Welcome, everyone! After saying that, he took the lead in applauding.

After being in contact with the Xingyue Tribe for a long time, Gray naturally knew that the Xingyue Tribe was welcoming them in this situation, so he immediately pressed his hands and said to everyone: "No need, no need, what kind of big chief am I!" Compared to your Xingyue tribe, we are not like Xiao Xiami! ”

Gray's words caused everyone present to burst into laughter, one of whom said: "But you are the largest trading tribe, without you, we would not be the same as other small tribes!" ”

Seeing this, Ye Feng greeted everyone: "Let's go, Chief Gray has come so far, let's go into the cave and greet him!" ”

So they dragged Gray and the others into the cave enthusiastically, and after some commotion, they built a bonfire and began to barbecue. It is said that since there was an oh pot, the people of the tribe in July have rarely eaten barbecue

"Ye Feng, you are a big tribe here, and no one will come to attack you, why do you still build such a high city wall?" Gray was stroking, and others asked at Ye Feng.

"Just because the people here don't attack us doesn't mean that the rest of the world doesn't attack us. And more importantly, have you heard of the giant bear that was making trouble with us a while ago? ”

As a trading tribe, the Rock Tribe is naturally very well-informed. Duoye nodded: "I heard a small tribe say that there is indeed such a thing, I didn't believe it at the time, but there are more people who say it, so I believe it!" ”

"So, I was afraid that the bear would come back, so I built this city!"

"Then other tribes don't have this defense, why do you think of building this kind of wall?"

"At that time, the giant bear attacked, the route taken just passed by our tribe, if it was closer, our tribe may be gone, I was afraid that the big bear would come back, so I built this wall first, to prevent it, if it did not come, it can also prevent the enemy."

The two talked happily, and before they knew it, they had talked until night.

"Chief Gray, the night will be very fierce, why don't you stay and rest tonight, and leave tomorrow?"

Gray thought for a moment and nodded, "Okay, you'll trouble you!" ”

"Haha, what's not troublesome!"

………

The night was silent, and the morning sun shone on the horizon as scheduled.

"Ye Feng, let's go, you see that you have all sent it so far, just send it here!" In the famous canyon of the Xingyue Tribe, Gray said to Ye Feng and the others who came to see him off.

"What, Chief Gray, don't you stay and play?" Ye Feng said.

Gray smiled, waved his hand, and said, "No need, I still have urgent matters, I must return to the tribe immediately, let's go first." ”

Seeing Gray's backs as they drifted away, Ye Feng suddenly asked the root of the tree next to him, "Huh?" What did you say Gray was in such a hurry to go back to the tribe? They can't be something, right? ”

Tree root thought for a moment and said, "According to their people, it seems that Gray's woman is about to give birth. ”

"What? He's going to be a father! Ye Feng's face was full of disbelief.
