Li Yuan nodded and said, "Interesting! As long as there is a reward, the government soldiers will actively participate, archery and ...... Lapidation? What is a stonethrow? ”

Leng Feng explained: "Throwing stones is to set a target in the distance, and the soldiers practice throwing heavy stones such as thunder to improve the accuracy of throwing thunder. ”

Li Yuan nodded again: "I see, these two things can indeed improve the accuracy of archery and throwing." By the way, do you want the government soldiers to practice these two things, do you plan to equip the government soldiers of the whole Tang Dynasty with thunder arrows and thunder in the future? ”

Leng Feng smiled bitterly: "How is it possible, how can these two things be universally equipped." ”

Not to mention anything else, thunder arrows and thunderbolts are gunpowder weapons, although Zhang Zhongqing set up a gusset protective fuse for it, but he is not afraid of 10,000 just in case, if he injures someone, whose responsibility should it be?

Moreover, the government soldiers cannot be equipped with gunpowder weapons, and can only be equipped with equipment when they go to war. As for why, just refer to the endless shootings in a certain big country in later generations.

Many people are angry, and their own brothers will fight, just intersect with fists and feet, and if the younger brother can't beat the elder brother, they will blow up with thunder......... At that time, gunpowder weapons will definitely become the most terrible thing in Datang, endangering everyone and even causing chaos in the world.

Li Shimin also said: "Father, thunder arrows and thunder are the important weapons of the country, and only the imperial court can firmly grasp them!" ”

Although Li Yuan has done a lot of trouble, he is not a faint king, and he quickly thought of the stakes, and couldn't help but say: "That's true, forget it, let's not talk about the thunder arrow and thunder, let's talk about that...... That one...... The matter of the Taishang Emperor's Cup Athletic Tournament. I still have a lot of pension money, and this kind of strong country event can't just do these two, nor can it last for a year, it should be an eternal example!

Archery, stone throwing, running, jumping, horseback riding, martial arts...... These should all be set up competitions, Emperor, you are also the commander of a hundred battles, you see which of these projects are beneficial to the army, you can choose which ones. ”

Li Shimin bowed down.

After saying so many words, he also sat on the dragon chair again, Li Yuan suddenly felt that it was boring here, and it was better to go back to the harem and ask his three grandsons to play badminton with him.

Hey? Badminton? Badminton!

"Wait, I'm going to add another badminton game, and I'll be there, huh."

Li Yuan loves badminton to death, anyway, he pays for it himself, and he has to add badminton to everything, no one can persuade him, I still want to abuse heroes all over the world.

Li Shimin saw that his father looked like he would spit on whoever dared to dissuade him, and the corners of his mouth twitched slightly, but he thought that badminton could also strengthen his body, so he said: "Father and the emperor personally instructed the child to set up this item." ”

Li Yuan smiled with satisfaction, and suddenly remembered the scene where Leng Feng abused him and even their father and son, so he pointed at Leng Feng and said, "You can't join the war!" ”

Leng Feng is cold, Li Yuan is now sitting on the dragon chair and pointing at himself looks more like a child, or splashing skin, isn't it just to deduct a few balls from you!

"Emperor Taishang, if you have to escort Geng Guogong to Lingnan in the near future, you won't be able to participate in the competition."

Feng Ang was about to leave before the autumn hunt, but it dragged on for another three or four days, and if it dragged on, Feng Ang would have to spend the New Year in Chang'an.

After finalizing the badminton to join the game, Li Yuan stepped down from the throne, and now he finds that it is really not interesting to be the emperor, and it is still comfortable to be the emperor!

……………

Feng Ang had a grand etiquette when he came, and naturally he couldn't wait for him when he left, so Li Shimin decided to hold a state banquet tonight to see Feng Ang off.

This time, Leng Feng did not participate in the state banquet, but had to hurry up and explain the matters of the Thunder Division, Tianxia Tower, Wenyuan, and Tianxia Manor.

There will be no problem with the Thunder Division under Zhang Zhongqing's management, and all Leng Feng has to do is to leave Zhang Zhongqing with the knowledge of the flame reaction.

Not long ago, when he was working on the color of glass, Leng Feng recalled some of the chemical knowledge that he had forgotten in the corner, and the flame color reaction was one of them.

Why are fireworks in the sky colorful? Because of the flame color reaction, the metal or its compounds will change the color of the flame when burned. For example, purple fireworks contain K+, which is a compound that contains potassium.

If Zhang Zhongqing wanted to study the various colors of cloud-piercing arrows, he had to use the knowledge of flame color reaction.

After reading what Leng Feng wrote, Zhang Zhongqing said: "Actually, I already have a clue, but I don't have such a detailed record as you.

Since I learned the formula of gunpowder, I have also studied many warlocks' articles, such as Tao Hongjing's "Commentary on the Materia Medica" of the Northern and Southern Dynasties: "Burning it with fire, purple and green smoke rises, and the cloud is true saltpeter (KNO3 potassium nitrate)." ’”

Leng Feng didn't expect that Zhang Zhongqing would be able to turn things out of the pile of old papers, nor did he expect that the flame reaction of his self-righteousness was the knowledge of later generations, which was recorded as early as the Northern and Southern Dynasties.

The ancients were amazing! This is what Leng Feng wanted to shout.

After reading what Leng Feng wrote again, Zhang Zhongqing got up and walked outside.

"Why are you going?" Leng Feng followed Zhang Zhongqing out of the house.

Zhang Zhongqing waved his hand and said, "What should you do, why do you go, I'll go and experiment." With this piece of paper of yours, I guess I'll be able to get it out in ten days. ”

I won't be able to see it in ten days! Leng Feng sighed and walked towards the side of the Academy, if Feng Ang hadn't been poured down tonight, then he would have to leave tomorrow morning.

The Academy of Literature has Mr. Han Chongwen presided over them, in fact, there is no need to worry about it, these old gentlemen are extremely square people, and they will never allow students to waste time, even if there is a class of high-ranking officials.

The teachers and students of this era are the real and universal "like father and son". Yu Huanzhi occasionally felt cold, had a fever and insisted on lecturing, but fainted in class. The five students he brought with him were undressed and took care of him all night for three days, he was a strict self-disciplined person like Yu Huanzhi, and when he woke up and saw five students with dark circles, he couldn't help but cover the quilt and cry bitterly.

Although the Martial Academy is not recruiting people for the time being, the facilities have been almost built, and when the education system of the Academy grows, what Leng Feng needs to do is to continue to provide money to the Academy.

As for the downstairs of the world, Leng Feng doesn't have to worry about it, Lao Yuan is a business wizard, and he is already planning to go to Fuxingfang to open the downstairs of the world.

Feng Ang was not overwhelmed by the emperor and courtiers, and although he walked staggeringly, he still got up the next day without delaying his departure.

Li Shimin led a hundred officials to send Feng Ang out of the city, and the prince led a hundred officials to send Feng Ang ten miles away.

Next is the Lingnan volume, thanks for today's day of the week and the only. A monthly pass!
