After eating, Ye Xi went to take a look at the baby aphids in the stone jar.

Each stone jar is covered with half a jar of fresh green leaves, and the mouths of these aphids are like sickles, clattering and gnawing leaves. These baby aphids are very smart, and when they find unfamiliar faces, they have a pair of black bean eyes, and they don't gnaw on the leaves, so they just stare at Ye Xi.

Ye Xi thought that these aphids were very squeamish, so he smiled on his face, beckoned to them, and said, "Hello." ”

The black bean-like eyes were still staring at him, motionless.

Ye Xi was a little embarrassed, coughed, and coaxed in imitation of the tone of the Aphid people: "The babies are very beautiful today, and it is very powerful to eat so many leaves!"

As if pressing the play button, the aphids lowered their heads and continued to nibble on the leaves, clicking.

Ye Xi breathed a sigh of relief and asked the ebony beside him: "Is the aphid we eat produced by aphids?" He just saw a translucent aphid the size of a pigeon's egg in the stone jar.

"Yes, the babies are very powerful, and they can give birth to a lot of aphids in a day!"

Ye Xi asked with some hesitation: "So, these aphids are theirs...... Excrement?" The three words excrement were said very lightly, thinking of the aphids that he had eaten all the food, Ye Xi's face was a little dark.

As soon as the words fell, I saw that Ebony's face changed, and he pounced on the stone jar, and said a basket of good things to the aphids, and coaxed them, and then pulled Ye Xi to the distance, and whispered: "What you just said is too disgusting, the babies will be sad!"

Ye Xi: "......"

Ebony: "And the aphids are not their droppings, their droppings are black and cannot be eaten." ”

"Whew-"

Ye Xi breathed a sigh of relief, it's good that it's not. Presumably, these aphids are similar to bees, honey is something made by worker bees storing nectar in honey bones, and these aphids must have similar organs.

Ebony said that the aphid droppings were black, and Ye Xi suddenly thought of the black things on the grass of the rubber forest, and asked, "Did you pour the aphid droppings into the back forest?"

"How do you know?" Ebony blurted out, but then thought that Ye Xi had arrived in Houlin, and he might have seen it more carefully, so there was nothing strange about it, so he said, "Yes, we all lost it to the back mountain." ”

Ye Xi pondered for a moment and asked, "...... Does the feces of aphids have a growth-promoting effect on plants?"

The rubber trees were unusually tall, and the rubber trees of the same type he had seen in the Ye tribe were almost half the size of them. The Ye tribe can be regarded as good at raising plants, and even the rubber trees they raise are only so big, there is no reason why the Aphid tribe can raise them so well.

Ebony was stunned when he heard this: "I don't know, I haven't paid attention." ”

Ye Xi's expression was solemn, and he said, "Ebony, can you do me a favor?"

"Of course, you say. ”

Seeing Ye Xi's solemn appearance, Ebony hurriedly agreed. At the same time, he decided in his heart that no matter how difficult it was, as long as he did not betray the tribe, he would do his best to help Ye Xi complete it. Because Ye Xi was the first foreign tribal friend he knew, he cherished it very much.

Ye Xi: "Can you pour aphid droppings around other trees in the future?" ”

Ebony, who was still waiting for Ye Xi to continue, waited for a while, and found that there was no follow-up, so he stared at him and confirmed: "That's it?"

"Well, that's it. ”

Ebony exhaled and said with a smile: "You asked me so solemnly, I thought it was a big deal." It's such a small thing, naturally it's okay, I'm going to dump the aphid droppings somewhere else today. But can you tell me why you're doing this?"

Ye Xi's expression was solemn: "I suspect that the feces of your aphids are good for the growth of plants. ”

Even if there are benefits, what if there are benefits? Ebony didn't understand why Ye Xi attached so much importance to this matter.

Ye Xi knew that he didn't understand when he saw Ebony's expression, shook his head and explained: "The Ye tribe is a tribe that loves plants very much, if the feces of your aphids are good for the growth of plants, what would happen to you?"

What will happen? Ebony froze again.

Ye Xi continued: "And we Tu Shan are also growing edible plants, if your aphid droppings are sure to be useful, we Tu Shan are willing to exchange other things, such as snowflake salt, animal skins, etc., for you." ”

"Salt in exchange for the feces of our aphids?" Ebony widened his eyes and waved his hand, "It's just dung, how can we ask for an exchange, if you need it, just take it! ”

Ye Xi smiled and said, "If it really works, then the feces of the aphids are not just feces. ”

If it is determined to be useful, then the yield of the grain grass can be increased. Thinking of this, Ye Xi's heart was hot.

After repeatedly explaining this matter to Ebony, Ye Xi talked to Chief Ephid.

Since it has been decided to make leather boots into a mountain industry, the demand for rubber is not one or two barrels.

Ye Xi was no longer a little uncomfortable with the Aphid Chief who still had a straight face at this time, and said with a smile: "Chief Chief, the white sap of your back mountain forests is very useful to our tribe, I don't know if I can exchange it with you for a long time?"

The rubber trees in the mountains behind the aphids are too tall and dense, and the roots under the soil are entangled, making it difficult to transplant, so they can't be asked to sell the rubber trees to them, so they can only supply rubber.

The thick black eyebrows of the Aphid Chief furrowed, his face became even more fierce, and he said coldly: "We don't use this thing, you can take it if you use it, you don't need to exchange it!"

Ye Xi said: "But we will need this sap for a long time, not once or twice......

Chief Ephid interrupted his words with a wave of his hand, and said forcefully: "Take it when you want it." After a pause, he added, "Or we can send it to you." His tone was much softer, as if he felt that he was speaking too stiffly.

Ye Xi was a little moved.

He could tell that Chief Aphid was sincere when he said this, and he didn't want to make a fortune from this rubber.

The Aphid is a more communicable tribe than the Leaf Tribe. He dared to guarantee that if Tu Shan and E-Aphid were on good terms, and an enemy would attack Tu Shan, E-Aphid's people would definitely send people over to support the first one without saying a word, and they would never secretly make small moves or small calculations.

Because of this, Ye Xi couldn't let the aphid suffer: "No, we must exchange things for something, even if it is a friend, we should settle it." ”

Chief Ephid was stunned when he heard the word friend, and secretly glanced at Ye Xi, his eyes were shining.

Do they have friends too, and shouldn't people from other tribes find them difficult to get along with, or think they are abnormal?

Chief Aphid's voice softened a lot: "Then let it be, but a pound of salt is too much, half a catty." ”

Ye Xi became tough: "No, just one catty." In fact, one pound of salt for ten pounds of rubber is already a loss for the other party, and he can't bully the disgusting and kind Aphid like this.

Seeing Ye Xi's attitude so resolute, Chief Ephid hesitated before saying, "...... Well, well. ”

The promise was extremely reluctant.
