Although Wei Chigong is a Xianbei surname, but it is not a Xianbei species, when the Wuhu is chaotic, the Xianbei military group often follows the soldiers under the command of the first surname of the army. At that time, the fighting in Shuozhou was fierce, and the locals closed their eyes in order to survive and eat a mouthful of food, and changed their surnames with the military leader.

Not to mention the old devil, Li Dongzu has also changed, not to mention the classic case of "Pu Liuru".

Originally, according to the general law, even if Wei Chihuan did not have half of his father's force value, he should at least sweep Wu Benfang.

Unexpectedly, his brothers even swept Pingkangfang, and as a result, Wei Chihuan was still studying the proof of "Ptolemy's theorem".

Of course, a certain engineering dog changed this theorem and stuffed it into "Zhang's Geometry".

Yu Chihuan's talent lies in the fact that he has a mathematical sensitivity far superior to Li Chunfeng and his ilk, as well as a very strong logical deduction ability.

To put it simply, if he were to live 1,500 years from now, he would be the kind of person who would be woken up by a teacher who slept on a desk and was hit with a chalk head, and then the teacher asked, "Do you know everything?", he really would...... It's embarrassing.

"Brother, look, when the thunderstorm is coming, the lightning flashes and thunders. But why do we see the 'fire flash' first and then hear the thunder? ”

Sao Nian, let me go, it was wrong for Qujiangchi to sell poems to you back then, and I was wrong, can't I?

"Fire flash" is lightning, and there is also a "live flash", Yu Chihuan has been following Lao Zhang, a native dog in the south of the Yangtze River for a long time, and occasionally purring out of his mouth, which is also the Jiangnan dialect.

"Uh...... Ah Huan, why do you say that? ”

Seeing the current Wei Chihuan, Lao Zhang finally understood why Li Shimin wanted to kill him when he was like this at the beginning.

A cute and cute beautiful boy, isn't it good to be a quiet beautiful man? I'm going to disgust people.

"This shows that this 'fire flash' is faster than thunder."

"The electric mother is a little more powerful than Lei Gong."

"Brother Mo is laughing, according to the younger brother, I am afraid that this voice is slower than 'fire flash'. Things in the world are fast and slow, people run slower than horses, and this thunder is slower than lightning, which is very reasonable. ”

Yes, it makes sense. The speed at which sound travels through the air is 340 meters per second, and the speed of light is 300,000, which of course makes sense. But you are the son of the Four Heavenly Kings, you are not the "Mechanics Ancestor Isaac", and you are not the "Electricity Control Maniac Franklin".

"Brother, younger brother has another idea. The younger brother found that in the middle of winter, it was dry and dry, and if it was woven with Mo Nan wool, and the clothes were turned over at night, there was a firelight 'crackling' sound. The younger brother asked Ah Niang, and Ah Niang said that there were gods in the family, which was a good thing. After a pause, Yu Chihuan looked at Zhang De very excitedly with a cute little face, "Brother, little brother doesn't think so." The younger brother felt that the sound of the firelight 'crackling' was like an amplified thunder. Brother, you think, there is thunder after the lightning, and this woolen thing must also have a "lightning" as if there was a small "crackling" sound. ”

“……”

What more can I say?!

At the same time, Yu Chihuan seemed to have received encouragement, and his eyes lit up, "If the wool weaving thing is sounding, the lightning flashes for a moment, and it stings slightly." The younger brother had seen a ploughing ox struck by lightning, and he must have suffered a great deal of pain to have such a tragic situation. But the younger brother thought about it, if it weren't for the 'fire flash' produced by this woolen thing that was far weaker than the thunder that struck the ox, wouldn't people be like the ploughing ox? ”

“……”

"The younger brother thinks that the thunder and lightning in the sky are similar to the 'fire flash' and 'crackling' of woollen things."

“……”

Ha...... Just now I remember how it was acousto-optics? How did it turn into a bold speculation generated by static electricity in the blink of an eye?

Lao Zhang's whole person is not good.

Sao Nian, your father Patrick Gong is in good health and has a high social status, why do you force yourself to be Franklin?

"The younger brother wants to borrow the paper kite in his brother's workshop, guide the thunder and lightning with gold and iron, and then tie the paper kite rope to the field chicken, rabbit and sheep, mules and horses. If the younger brother guesses correctly, if this thunderbolt is ......"

Okay, isn't it okay for Lao Tzu to admit defeat? Your dad is Patrick Konne, and you're Franklin Ring!

When sending Wei Chihuan home, the man in Liangfeng County was stunned throughout the whole process, and when the old devil's family followed Huanlang into the house, Lao Zhang thought about it and admonished: "Ah Huan, these things, just think about it, don't try it." Even if you want to try, you have to come as a brother. ”

"Okay."

Good for your sister!

"Alas......" Looking back at Wei Chi Ritian's mansion, the home of the capital protector of Anbei, isn't it good to have some strong men? What a plane!

Lao Zhang very much hopes that the Dahe Workshop will burst into geniuses, so that the sequelae of the operation will be small. In the future, we will not be drawn into a dead end because of political struggles.

Wei Chigong's descendants, this generation of emperors is fine, and the next generation of emperors may be fine, but they must still settle the accounts.

Xuanwu Gate, it's a pit there.

"Alas......"

With another long sigh, Lao Zhang slapped himself, "I'm not a fool, I'm a genius, and sooner or later I still have to deal with bureaucrats." Isn't Yu Wenkai a lesson from the past? ”

Then Lao Zhang slapped himself again: "Damn, it seems that He Tong's grandson is working for the old devil." ”

Wei Chigong's construction of the Anbei Metropolitan Protectorate, the superintendent is the grandson of He Tong, the son of He Chou, and He Lonely.

Then He Lone's son, He Fang, followed the old man Wang Xiaotong to learn mathematics. "The Ancient Calculations" or something, it has changed beyond recognition.

"Alas......"

With a long sigh for the third time, the engineering dog was entangled to the extreme, "Why is it from Wei Chi's family?" ”

However, Lao Zhang also thought about it calmly and felt that this was reasonable. Nobles must have more time to eat, drink, socialize, and fight than commoners. Similarly, among the nobles, the big nobles must have more time than the small nobles to think about what they don't. Then among the big nobles, except for the eldest son, the rest of the sons-in-law have to think about how to start a family, and the concubines have to think about the way out in the future.

A sister-in-law like Yu Chihuan, who is a teenager younger than his brother, is the most relaxed.

Don't worry about food and clothing, what you want, the material pursuit can already give up the treatment, and the rest are the following stages of Maslow's hierarchy of needs.

"Alas...... Into the mother's. ”

With a long sigh in the fourth, the Liangfeng County man walked towards Nancheng with a slight depression.

Wuzhuang Guan, the activity center of the old cadres of the Tang Empire, is now very different. The drains are made of cement and covered with stone slabs. On both sides of the road, there are either fertile fields or forests, and the scenery is particularly good.

The pavilions and pavilions have a garden style, which is very different from the thickness of Chang'an City.

On Qin Qiong's mansion, Menzi saw that it was Lang Jun riding a black horse, and he was immediately enthusiastic. Lao Zhang guarded seventeen or eighteen guards on the left and right to tie up the horses, and then said to Zhang De: "Langjun, let's go wash the beasts and make up some beans." ”

"Go ahead."

Farewell to the guards, after Zhang De entered, he saw a bear child lying on the ground, pouting his ass and exploring something.

"Xiaolang, hurry up, it's very cold outside the house."

"Wait, wait...... Ha, you see, it's dead, it's all burnt. How about it, that's right, this glass is very useful! ”

The bear child is four years old, but he speaks very slipperily, and most importantly, what he holds in his hand is a magnifying glass.

looked familiar, it seemed that he gave it to Qin Qiong's wife to watch the stitches......

What I never expected was that there was also a bear child in Qin Qiong's mansion, and his magnifying glass burned ants in the sun.

Ha...... Zhenguan's eight-year painting style is a little different.

For a moment, the engineering dog wanted to turn around and go home. (To be continued.) )
