"Okay, but Xiao Kui said that he wanted the cannon in Xiao Yu's mouth, so he asked Xiao Yu's godfather to say that he couldn't find him if he admitted defeat, so he was willing to come out. Otherwise, even if he doesn't eat, he won't come out. Zhou Xiuying said embarrassedly.

"Sister-in-law, I just said it casually, I didn't expect Xiaokui's child to take it seriously, and what's even more annoying is that I can't even find a child of him, it's really a shame. Sister-in-law, you can be merciful and tell me, where is Xiao Kui hiding! That cannon really can't be given, it's used to fight, it's very dangerous, it's easy to hurt our own people, and we're very careful when we use it, don't believe you ask our chairman. ”

Supreme Treasure nodded in agreement, Zhou Xiuying thought about it and looked down at her feet.

The Supreme BMW reacted to where Xiao Kui was hiding, he took out the paper airplane in his hand and said with a smile: "Xiao Kui, come out quickly, Godfather has prepared a thing for you that is more fun than a cannon called a paper airplane, you see!" ”

Lu Xiaoyu saw that Zhou Xiuying made a very small voice behind him: "Wait for me to get the cannon, and then take the paper airplane." ”

"Xiao Kui, godfather found you!"

"Oh, mother, how can you tell your godfather secretly!" Xiao Kui pouted and said unhappily.

"It's wrong, my mother didn't say anything, you heard it, it was you who made your own voice to let your godfather find it, you can't blame others."

"Okay, Xiao Kui, don't be angry, wait for the next time your godfather will take you to Jiangcheng to see the real magic cannon taking you to put two cannons, okay?" Lu Xiaoyu hugged Xiao Kui and said.

"Godfather, you can't regret it, I'm going to put it myself. I'm going to blow up those enemies too. ”

"Good boy, it's not easy to want to be a gunner at such a young age. Let's try this paper airplane first, it's just as fun as a cannon! "The paper airplane in the hand of the Supreme Baoxiu gave it to Xiao Kui.

Xiao Kui had already heard the paper airplane that Supreme Treasure said, and after he took the paper airplane, he frowned and asked, "Godfather, how do you play with this paper airplane?" ”

"Does the kite know?"

"Is this little thing a kite?"

"This little thing is the son of a kite, you see it's so small, it's a kite that you can put in your hand. I'll show you how. Supreme Treasure sighed at the head of the paper airplane, pulled out the posture and threw the paper plane into the air, the paper plane drew a beautiful arc in the air, and finally landed smoothly more than ten meters away from them.

"Wow, it's fun, godfather will teach me how to play!" Xiao Kui said excitedly that for children, there is a dream of flying. And this paper airplane can be regarded as the fulfillment of their dream.

"Come on, pick up the paper airplane and I'll teach you how to play it."

Xiao Kui had already jumped over with a paper airplane and held the paper airplane in his hand.

"First of all, you have to pinch the paper airplane here with your index finger and thumb." Supreme Treasure teaches Xiao Kui how to hold a paper airplane hand in hand.

"And then take a breath on the head of this paper airplane."

"Godfather, why do you want to take a sip on this, is it any use?"

This problem has also plagued Supreme Treasure for a long time, but later Supreme Treasure consulted the relevant information and learned that there were three major reasons why the paper airplane was in the head before flying.

The first point is aerodynamics: the nose becomes heavier and balanced. Let's start with physics. The paper airplane nose is smaller, which can reduce drag, but it also makes the nose too light and the fuselage mass uneven. According to aerodynamics, the wet nose of the airplane is slightly heavier, which can keep the fuselage in balance, and the heated nose can also keep the paper airplane in the air for a longer time. In addition, the slightly heavier nose of the fuselage can play a driving role, and if the rear of the fuselage is too heavy, the paper airplane is prone to backward flips during flight. In reality, before the aircraft actually goes into the sky, it has to carry out wind tunnel experiments in aerodynamics. Through wind tunnel experiments, the aerodynamic forces of the aircraft model were measured to determine its flight performance. Measure the surface pressure distribution, determine the load and strength, etc. So you can think of the paper airplane as a miniature version of the wind tunnel experiment.

The second point is psychological suggestion, the herd psychology seems to be very reasonable, but children don't think so much about playing paper airplanes. In the face of factors such as the weight of the aircraft itself, changes in air currents, and various unprofessional flight throwing actions, the actual effect that can be brought by a breath of air can not be smaller. Therefore, in addition to the first person who invented this method, we juniors are all herd behaviors, and we always feel that Ha Qi can make paper airplanes fly higher and farther, and after getting used to Ha Qi, it will evolve into a psychological prayer, or a way to improve our concentration.

The third point is folk rituals, in daily life, throwing dice, throwing darts, or taking a breath and blowing before hitting your boyfriend with a small fist, such actions are intentionally or unintentionally imitating some ritual actions. For example, some folk rituals are to breathe a sigh of breath to the tip of a pen, and some are to breathe a sigh of breath to a sacrifice, which also appears in various practices of shamans and shamans. The act of haqi seems to emphasize the purpose of the act and strengthen the role of the ritual. Tracing back to the roots, we can also see the magic of Ha Qi from the myths of the East and the West. The Eastern Nuwa and the Western God made people out of the soil in their own appearance, and in the end, they had to breathe a sigh of breath to have spirituality. In Journey to the West, Sun Monkey's plucking is also through exhalation to achieve thousands of incarnations.

But of course, it was impossible for the Supreme Treasure to tell Xiao Kui about these profound things, so he said: "Godfather, this is casting a spell on a paper airplane, and after casting the spell, the paper airplane will grow wings and fly on its own." Now I'm going to teach you this method, don't give it to anyone else! ”

As soon as Xiao Kui heard what the Supreme Treasure said so mysteriously, he nodded seriously and promised not to tell this secret.

Xiao Kui tried it according to the method that Supreme Treasure said, and sure enough, the paper airplane crossed a beautiful arc in the sky and landed in the pond in the courtyard.

"Wow, the paper airplane flies so high and far, but unfortunately it falls into the water and can't fly." Xiao Kui picked up the paper airplane in the pond that was wet and couldn't fly, and said dejectedly.

"It's okay, there's a godfather, I'll teach you to fold this paper airplane, it's very simple."

In this way, Xiao Kui and Supreme Baole folded the paper airplane without being hungry, while Zhou Xiuying and Lu Xiaoyu prepared dinner for them, and the four of them spent a happy night like a family.

There is no banquet in the world that will not be dispersed, and after a pleasant dinner, Supreme Bao, Lu Xiaoyu and Zhou Xiuying's mother and son finally parted. Supreme Treasure and Lu Xiaoyu have to continue their private visit to Weifu, and Xiaokui and Zhou Xiuying have to go back to their tofu shop to sell tofu.
