"Dad, you're really amazing. Ding Yan admired Ding Mu more and more, but his curiosity did not diminish in the slightest. His eyes were full of a teenager's curiosity, "Dad, you said that there are aliens, so what is the highest level of civilization for aliens?"

Ding Mu groaned: "Son, this question is difficult for Dad to say. However, we believe that there must be aliens from different civilizations. I think there should already be aliens above the second level civilization. This is judged by the sixth sense. And if there are really aliens who can come to Earth, then the level of civilization where this alien is located must be more than one level. ”

"Dad, what is the sixth sense?" The child's mind is always jumping, and he cares more about the sixth sense.

"The sixth sense is the common name for extrasensory perception, also known as mental awareness, which is the ability to receive information through channels other than the normal senses, to predict what is going to happen, or to judge the unknown. Ding Mu grabbed Ding Yan and tested him, "Son, what are the five senses of ordinary people? How do you perceive this world?"

Ding Yan tilted his head cutely, thought for a while, snapped his fingers and said, "You can see with your eyes, hear with your ears, smell with your nose, lick with your tongue, and taste the taste." What else is that?"

Ding Yan snorted on his face, pointed to his eyebrows and said, "You can also use your eyebrows here...... Hmmm......"

"Hahaha. Ding Mu saw that his son thought that the five senses were all organs of perception, touched his eyebrows, and considered what his eyebrows could do, and couldn't help but laugh and said, "What can you perceive with your eyebrows?"

"I can emit ultrasound waves from here, and then judge the distance based on the reflection of the ultrasound waves, like a bat. Ding Yan was only a six-year-old child after all, he parted his fingers, first tapped his two eyebrows, and then poked forward with his hand, making a groaning sound in his mouth.

"Hahaha. Ding Mu looked at his son's cute appearance and said, "You have a superpower." Dad asked what the five senses of ordinary people are, okay, Dad will tell you. The first four you said are all right, the senses of ordinary people, including eyes (sight), ears (hearing), nose (smell), tongue (taste), and the last one is the touch of the skin. ”

"Oh...... By the way, I can touch it. Ding Yan finally figured it out, "But, Dad, why are most of the sensory organs concentrated on the face?" ”

"Good question. Ding Mu picked a thumbs up and said, "This has something to do with the evolution of animals, and this question can probably answer your question of whether aliens are similar to humans." I guess if there were aliens, they would be similar. They must have a head, a torso, and limbs, and they must also be symmetrical.

It's about sports. Symmetrical limbs are the most efficient, and multi-legged limbs do not increase efficiency, but rather increase energy. Unless the gravity of a planet is very large, then the animals on it must be more than enough to share the weight of the body, but then it will be difficult to evolve such a highly intelligent animal as us.

In addition, the sensory organs must also be located in the direction of progress, and at one end of the body, which is also conducive to improving efficiency. Unless it is an animal that does not need exercise, it must be such a result. Walking upright and freeing your hands is also an inevitability of species evolution.

To put it simply, the planet suitable for human habitation has a fixed range of gravity, and the size actually has a specific range. And this kind of human appearance of us is a unique form. ”

"Dad, I feel very proud to be born as a human being. "Ding Yan is like a little adult.

In fact, what Ding Mu said may not be all right, but he must instill positive energy in his son, so that he is full of curiosity about this vast universe and proud of his existence. He was very happy to see that the child was interested in the universe, after all, he was already a veritable rich second generation, the person at the top of the pyramid. Only the vast sea of stars is the place where he can display his ambitions.

Ding Mu took off the dzi on his wrist, adjusted the length, and put it on Ding Yan's wrist, he said: "Son, this is a dzi, it was given by my father's senior brother, it is very precious, and I must always wear it on my body." ”

"Thank you Dad. Ding Yan looked at the bells and whistles of the dzi and asked, "What is the dzi?"

Ding Mu Zhengse said: "This is a treasure, the ordinary dzi is agate, cat's eye stone, a kind of gemstone, commonly known as the nine-eyed bead." Medication can treat cerebral hemorrhage. The earliest dzi is called Zhangzhung Dzi, which was born in the ancient Zhangzhung Kingdom, the most powerful ancient civilization across Central Asia and the Qinghai-Tibet Plateau, and it is the sacred relic of Yongzhong's religion. The dzi that Dad gave you is the most precious treasure among them, and it is said that it is a meteorite in the sky that fell to the earth and turned into a sacred stone. This is the only one in the world, this is the first gift that Dad officially gave you, don't give it to anyone else. ”

"Hmm. What Dad gave me, I wouldn't give to anyone. Ding Yan agreed.

Ding Mu also advised, afraid that he would not take what he gave seriously, and then transfer it to others at will, this dzi is no more and no less, and it is worth hundreds of millions of dollars.

Seeing that Ding Yan cherished the things he gave him, Ding Mu smiled and continued: "Son, until basically no one in the world can hurt you, you can give this thing to the person you love the most. ”

"Oh. Ding Yan nodded thoughtfully when he heard this somewhat complicated sentence, although he didn't quite understand, Ding Mu could see that he had memorized this sentence firmly, and he should be able to do what he said.

The relationship between father and son quickly sublimated, and Ding Yan said: "Dad, just now you said that if aliens come to Earth, their energy level must be more than one level, that is, they are more powerful than us." If they attack us, will we lose the battle? I'm afraid. ”

In fact, Ding Mu already had a hunch that if there were aliens, a large-scale war was very likely to come quickly, and the rapid arrival of this war was directly related to Ding Mu. Because it is Ding Mu who has promoted the rapid development of the earth's civilization, it may threaten the security of some existences. At this time, the stakes of war are extremely high.

However, Ding Mu didn't expect Ding Yan to be so sensitive.

He said solemnly: "Son, victory in a war does not depend entirely on the level of civilization, or even on the level of military strength. If it was just a contest for this, our motherland would have perished long ago.

When the ancient swordsmen met their opponents in a narrow way, no matter how powerful the opponent was, even if the opponent was the best swordsman in the world, they knew that they were invincible, and they had to show their swords. Even if he falls under the sword of his opponent, he is still glorious in defeat.

This is called the spirit of the bright sword, even if the enemy is outnumbered, even if it is encircled, but we dare to show the sword, we dare to fight to the last man. In a word, the brave wins when they meet on a narrow road. The sword is invincible.

Children, in the face of the vast galaxy, manpower is sometimes exhausted, and only courage can allow us to overcome obstacles. You are a man and deserve to be a true warrior. ”

Although Dingmu's words were not loud, they were very powerful.

When Ding Yan heard this, his mood was agitated, he patted his little chest and said, "Dad, even if you start a station with aliens, I will protect you! I will box!"

"No!" Ding Mu said categorically, "Dad will protect you, only the moment Dad falls, it will be your turn to make a move, and you are responsible for protecting Mom." ”

"Well, I'm in charge of protecting Mom!"
