In addition to some common sense, such as how to use fire and some common tools, and identify some edible plants in the forest, Simmons also tried to teach the experimental subjects to domesticate some animals.

"Have you ever experienced winter?" Simmons asked them. "In winter, the weather is very cold, animals rarely come out, and it is not convenient to hunt."

He told the subjects: "If you raise some animals in advance, you won't need to hunt or starve in winter."

The experimental subjects listened carefully to his words and felt that it made sense, but after the premise that some minor problems occurred in the first few attempts, they decided to ask Simmons first before doing it.

Simmons told the experimental subjects the skills he had learned based on his previous communication with other races. After the other experimental subjects left, Simmons looked at 76 and 77 who were still in place, and asked: "Is there anything else you can do?"

77 nodded: "I found a bird in a tree." It was a cub, its parents were probably caught by other predators, and it hadn't come back for several days. When 77 found it, it was in the nestAll the other baby birds were stiff, and it was the only one left.

After 77 found out, he gave it a little minced meat from its own food, so that it would not starve to death.

Simmons listened patiently, and then asked 77: "And then?"

77 Thinking about what Simmons said just now, raising the captured live prey in captivity, providing them with food, and then not starving when the food is scarce: "I want to continue to provide food for it."

"But I don't want to eat it." Even if this bird grows up, it is only 77's palm size, and birds are not in the diet of the experimental subjects.

He seemed a little confused about how to treat the little bird that he found accidentally. If 77 didn't take the initiative to provide food and shelter for it, then it would soon become food for other animals.

"So what do you think?" Simmons asked him.

"When it's hungry and screaming in the nest, it wants to live." 77 said, "I found it, and I can make it live."

He was just wondering if he wanted to keep the bird and shelter it to grow up.

After talking about their doubts, the two snakes looked at Simmons and tried to find an answer. Before that, they also thought about asking the stars, but based on their knowledge of the stars, the stars don't care about the life or death of a bird.

If it was a star, he should have told them that every day on this planet, a bird like this would die because of losing the protection of their parents, but he would also tell the experimental subjects to do what they wanted.

"Do what you want." Simmons looked at him encouragingly.

"But if it hadn't met me, it would have died soon due to various factors like the other little birds."

"But the moment it meets you, it's already different from other little birds."

——

Encouraged by Simmons, 76 and 77 had their first pet in the cave. It was a bird whose feathers hadn't grown yet. What they did most every day was to open their mouths and wait for food to be fed.

And the connection between the experimental subjects and Simmons became more and more close unconsciously.

The exchange between Simmons and the experimental subjects was no longer satisfied with ordinary items.When the experimental subjects felt the kindness from Simmons, and instinctively began to "exchange" the seedling head with prey or other items, Simmons could always accurately capture this message, and dispelled the experimental subjects.Intend.

He taught the experimental subjects common sense, and told them about the different planets and different people he met during his travels. After the story was over, Simmons looked at the experimental subjects who were about to turn around and drag a prey back, and took themstop.

"Do you want to exchange food for stories?"

The experimental subjects nodded.

"But the story I tell itself is something invisible and intangible, but the food you send over is not."

The experimental subjects stopped: "Then what do you want to exchange?"

Simmons said: "You are all very happy after hearing the story." He seemed to think about it seriously: "Since this is the case, I want to see you laugh out of happiness."

The smiles of the experimental subjects seemed restrained to Simmons, as if they had concerns, with restraint.

"I will also feel very happy to see that you are not suppressed when you are happy." Simmons said, "Just use this in exchange."

He said: "If you agree, I can continue to tell you the unfinished part next time."

——

The experimental subjects finally agreed to his request, but it has to be said that Simmons' request for exchange seemed extremely strange to them, but in their exchange, one thing remained the same.

Only food can be exchanged for food.

During other exchanges, Simmons was sometimes a flower they liked on the way to bring them over next time, sometimes it was a happy event that happened to the experimental subjects, or simplySit with them and look at the stars on an evening when you know the weather is good.

"It's so strange." The subjects discussed him quietly in private, but it was undeniable that they all liked this special human being.

The experimental subjects still follow the "exchange" rule, and after they feel that they have obtained something from Simmons, they must use other compensations to return it.

When the experimental subjects got used to this set of exchange rules and planned to continue, some minor accidents happened.

When an experimental subject was hunting, he saw a bunch of red berries in the bushes. He remembered that Simmons liked this kind of berries very much, and this kind of berries were relatively rare in the forest.

When the test subject saw the berries, he didn't think too much, for example, he was going to take these berries to exchange some snacks with Simmons.He just thought that Simmons would like it, so he happily took this bunch of berries to Simmons' starship.

He knocked hard on the door: "Is Simmons there?"

Simmons came out quickly.

"I'm here." He looked down at the experimental subject in front of him, "What can you do for me?"

The experimental subject showed him a berry tree behind him as if asking for credit: "I remember you liked this very much." He looked around, trying to find a place to replant the berry tree in this area.

But unlike his excitement, Simmons had a slightly calm expression: "Take it away."

"Why?" The experimental subject was a little surprised.

"I don't have any food to exchange with you." Simmons said, although he has a lot of snacks in the starship, but after all, so many experimental subjects are here, it is enough to last for a month or two.Not bad.

He looked at the expression of the experimental subject, wondering how he would react.

The experimental subject seemed to be choking on his words. He stood there with his head down for a while, and found that Simmons' logic was indeed correct, but he didn't want to take the berries back with him.

"I don't want food." The experimental subject emphasized to him that the purpose of bringing the berries over was not to exchange snacks with Simmons.

He turned around in a hurry, finally grabbed Simmons' hand, and forcefully stuffed the berries into Simmons' hand, but Simmons refused.

"I remember when you first came here, you told me that we must exchange."

"But...but..." The subject's tongue was tied, and he finally managed to figure out his thoughts after stumbling, "I want to give it to you."

But Simmons still looked at him gently: "But I still don't have any food that I can exchange with you."

——

And this experimental body is just the beginning.

Because the experimental subjects often came to exchange with their prey, Simmons basically did not go out to hunt by himself. In the eyes of the experimental subjects, Simmons was a human being without the ability to hunt.

If we don't bring him food, he will starve to death here sooner or later because he can't catch prey...

With the above idea in mind, the experimental subjects often take turns to bring some food to Simmons, and Simmons always accepts what is ordered, and then returns corresponding snacks to the experimental subjects according to their exchange rules.

Before this, the experimental subjects didn't think there was anything wrong.

But after announcing that the snacks in his starship were gone, Simmons stopped accepting food from the experimental subjects.

Worried that he might starve to death, the experimental subjects gathered to discuss this matter.

The subjects gathered together and discussed this matter for an hour or two. 77 said, "We didn't bring him food just to get food from him."

The other experimental subjects also nodded in agreement, and the experimental subjects who had been rejected for sending food felt a subtle emotion in Simmons' rejection.

"We're going to have a serious discussion with him on this issue!" 35's tentacles patted the ground vigorously, and then she looked around at the experimental subjects around, "How about today!"

——

After waiting for a few days, Simmons finally waited for the day when the experimental subjects came to the door collectively because of their "ignorance of good and evil".

After hearing a knock on the door outside the starship, he walked out quickly, and unsurprisingly heard several experimental subjects complaining to him.

After they finished speaking, Simmons said: "You mean, even if you can't exchange snacks with me, are you willing to bring me food?"

"That is to say, the snacks are only incidental, and the food is just worried that I will starve if I don't have the ability to hunt?"

The experimental subjects nodded.

Hearing this, Simmons couldn't help but smile, and he asked the experimental subjects: "I've been refusing, are you angry?"

Several experimental subjects nodded, and under the guidance of Simmons, they took the initiative to say: "In fact, sometimes it seems that not everything needs to be exchanged."

Simmons smiled, and he looked at the subjects: "Not all the purpose of giving is to get something in return from the other party."

"Just like you, when you want to send me food, you just want to give it to me."

"I want to be nice to a certain person, not to exchange for something from him."

Simmons used several other subjects as examples: "Like 33 and 35, 76 and 77, when you want to give something to each other, don't you also want to get something from them at the same time?"
