"Do you still need to be taught by others, this is what I saw on the board. The board that Liu Yuhan said is exactly the same as the one in Liu Sheng's hand, a specialty of space science and technology, graphene tablet computer.

"Then tell me why you can't grow plants in the desert. Liu Long looked at Liu Yuhan dotingly, and then said.

"Dad, this question is too pediatric, you can learn about the elements of plant growth. Liu Rui not only replied at this time, but also gave Liu Long a look of contempt.

After being despised by his own family's divine beasts, Liu Long couldn't cry or laugh, so he continued to say to Liu Sheng, "If Xinsheng No. 1 can grow in the desert, then it will definitely be a thing for the benefit of all mankind. ”

"Young master, when I was researching and developing, I considered the desert, but I didn't succeed in researching and developing, maybe you didn't find that Xinsheng No. 1 has a characteristic, that is, although the root system is developed, but the soil is not deep, because he has no way to fix the sand, so as soon as the wind blows, the plant will be blown up again, so it can't be planted in the desert. Liu Sheng patiently explained to Liu Long.

"Is there a way to make their root system develop, so as to achieve the purpose of sand fixation? Although Liu Long doesn't know much about Xinsheng No. 1, this does not prevent him from having new suggestions for Xinsheng No. 1.

"For Xinsheng One, that's not possible, because their genes are fixed and there is no way to modify them, but I can re-study a plant that can be grown in the desert based on the data from the research on Xinsheng One, but his yield will definitely be affected. ”

For biological research, Liu Sheng can be said to be authoritative, otherwise it would be impossible to study Xinsheng No. 1.

"Forget it, after all, the desert is also a landscape of the earth, if the desert disappears, maybe many years later, human beings will find a way to turn the oasis into a desert. Liu Long thought for a while and said.

Don't think that what Liu Long said is nonsense, but in fact, it is not, because he has seen through human nature.

Human nature is a bit hollow, because it is not an object, you can see and touch, human nature is divided into 12 kinds, namely, kindness, power desire, gambling sex, greed for money, lust, appetite, emotion, love of beauty, curiosity, leisure, jealousy, and praise.

And what Liu Long said may be many years later, someone will turn the oasis into a desert, which is the curiosity, leisure, and greed in human nature.

Don't underestimate the curiosity in human nature, there is an old saying that curiosity kills cats, which is the curiosity in human nature.

Curiosity can also be said to be the exploration and exploration of unknown things by adults, and some people will be particularly interested in areas with unknown geographical features, and even risk their lives to explore, which is the curiosity of human nature.

If, after many years, there are no deserts on the earth, some people with a better economic foundation and great curiosity may restore the deserts on the earth according to historical records, don't think it's nonsense, in fact, it's like some scientific research institutions are researching and want to resurrect dinosaurs.

And Xiaoyao is a kind of unrestrained human nature, Xiaoyao is expensive in no constraints, and there are no rules and regulations without constraints, so the size of the desert will be as you like.

And the existence of desire will make the free human nature more unrestrained, especially when there are interests, so what Liu Long said is not unfounded.

"Why, aren't many countries now trying to turn deserts into oases. Regarding what Liu Long said, Liu Sheng asked with some doubts.

"Forget it, I told you that you don't understand. Liu Long glanced at Liu Sheng and said.

As soon as Liu Long finished speaking, Liu Yuhan, a divine beast who was playing, suddenly said, "Actually, it's just desire." ”

After finishing speaking, he walked back and forth on the floor with his head held high, as if he had attained the Tao.

Liu Rui was not to be outdone, climbed from the sofa to the ground, and also followed Liu Yuhan's example, but his mouth was not idle, "Desire is the root of human progress." ”

When Liu Long heard what these two divine beasts said, he felt very reasonable, and then asked, "Baby, then tell me, why is it desire?" ”

"Hey, Dad doesn't seem to be smart at all lately, which really worries us about his IQ. ”

Hearing that Liu Long didn't understand something again, the two divine beasts suddenly felt that they were stronger than Liu Long again, so the two glanced at Liu Long and said to each other.

After all, they have been fighting with Liu Long since they were children, from fighting for the ownership of Yili to competing for various delicacies, and in order to fight with Liu Long, they are also familiar with the thirty-six strategies, and today is the second time that Liu Long has asked them for advice, how can they not be proud.

Hearing the words of the two divine beasts, Liu Long couldn't help but laugh a little, "Okay, Dad is not as smart as you, then you explain to Dad what desire is." ”

"Well, for your sake, I'll explain it to you, but when you're done, you'll have to pick the colored fruit from it for us and give it to us. Liu Rui said, and pointed to a small tree with colorful fruits not far away.

Liu Long was at a loss for this small tree, because he didn't know what variety it was, and he didn't know whether the colorful fruits on it could be eaten, so he looked up at Liu Sheng.

"Young master, this fruit tree is the fruit tree of genetic mutation that I have recently studied, I call him Zhu Guo, although his fruit is relatively beautiful, but the nutrient content is low and pitiful, and the taste is not very good, otherwise it would have been picked and eaten by the two young masters. Liu Sheng explained.

After listening to Liu Sheng's explanation, Liu Long said to the two divine beasts, "You have also heard, this colorful fruit is not delicious, but if you can tell me what desire is, then I will let Uncle Liu Sheng pick it up and give it to you." ”

The two divine beasts hesitated when they heard Liu Sheng say that the colored fruit tasted bad, but when they saw such a beautiful fruit growing on the tree, not in their hands, they replied, "Okay, then I'll tell you what desire is." ”

"Desire is the requirement of human nature to achieve a certain goal, there is no good or evil in desire, the key is how to control, the most primitive and basic instinct of all animals in the world, from the perspective of human beings, is a desire and satisfaction from the mind to the body, it is an indispensable need for the existence of all animals, and the most basic desire of all animals is survival and existence. First of all, Liu Yuhan introduced the definition of desire.

"In fact, the human nature that Dad just said is based on giving desire, and desire is an inevitable element that drives people and animals to survive, and it is also an inevitable element to promote social progress. Liu Yuhan was like a little adult, walking back on the ground, explaining his desires.
