With such a subtle festival, everyone present could see the weight of Diao Chan in the heart of the lord.

Empress Dowager He used to be the master of the deep palace, and the tricks of the palace fight have already been used, although after the ordeal, the heart has changed, but the eyesight is still there, knowing that the emperor cares about Minchan very much, so he nodded.

"Sit down!"

As soon as Liu Wei left her, Minchan felt weak and had no support, and it was not the first time she usually performed for the Queen Mother, but today's identity is very different from before.

"Sister, come and sit."

Tang Yu gently pulled Minchan to his seat, while Liu Biangang stretched out his arms towards the queen mother.

"Mommy, you want to kill me......"

Everyone in the backyard knew what this sentence meant, and Empress Dowager He saw that the emperor was so naughty, and she also had a smile on her face.

"Emperor, the queen mother misses you too."

Lying in Liu Wei's ear, Empress Dowager He asked softly: "You didn't want to reward you at the beginning, but now the monkey is in a hurry to take it home, why is this?" ”

"I want to capture the old and let her give birth to a son with all her heart." Liu Wei also replied softly.

"This still uses the art of war? It seems that the emperor's art of war has become like a realm of destruction. Empress Dowager He scolded Liu.

This emotional scene of the mother and son meeting made several women wet their eyes, and Liu Wei had already expressed his attitude towards Minchan to the queen mother during this time.

"According to you, what is the queen mother who does not depend on you now?" Empress Dowager He smiled like a flower, probably thinking about the descendants of the emperor and this Diaochan, there must be men such as Song Yu and women such as Xi Shi.

After Liu Wei and his mother separated, his eyes naturally glanced at Baoyu again, and he sweated profusely in his heart, and when he saw his slightly melancholy expression, he couldn't help but feel a pain in his heart.

It's been almost two years, and I still treat people as eunuchs, and children will grow up.

"Baoyu, come here, come here."

Liu Wei beckoned to Baoyu again and again.

Baoyu obviously had some resistance to Liu Wei, but he couldn't attack, so he had to come over unwillingly.

Liu Wei pulled him to his side, put his hand around his shoulder, and smiled at his mother and the beauties: "Look, these are the two most handsome men in the world." ”

"Yay......"

Hearing the lord's bragging, led by Leng Yun and Lu Yin, a few whistles sounded in the courtyard.

"My senior brother is more handsome than you." Lu Yin was not convinced and shouted.

Baoyu also didn't seem to agree with the lord's point of view, and struggled desperately, wanting to keep his distance from Liu Wei.

It's a pity that with her small body, after spending a long time, Liu Wei didn't move at all.

"Why is your body so soft? It's a bit like a young man who is already about to mature. Liu Wei just said it casually, so much so that Baoyu was so scared that he didn't dare to struggle anymore.

Minchan got Tang Yu's hint and didn't make a sound, but her eyebrows and eyes were full of smiles.

"No, when the spring begins, I must find you a beauty, there are many beauties in our art camp, and with Baoyu's merits, there is no problem in marrying a few.

Empress Dowager He saw Baoyu's face flushed with shame, but she was afraid that the emperor would see any flaws, and she was very satisfied with Baoyu.

So Empress Dowager He found a reason to let Liu Wei come over to speak, and Baoyu escaped from Liu Bian's clutches, and couldn't help but slap her robe a few times with her hand.

This action provoked a group of beauties to cover their mouths and snicker, and Liu Wei had been pressed by his mother's side, and everyone raised their glasses to drink together, wishing for a better future.

……

Wangdu City, Tiangong Academy.

Seeing Liu Wei walk in, Ma Jun stopped his movements and stood respectfully, but Huang Yueying still used her pen to calculate what quickly.

Liu Wei walked up and took a look, obediently, the female scientist was studying gravitational acceleration.

Physics is the cornerstone of science, and those who have physicists will be much ahead of their time in terms of vision and invention, but chemistry is too avant-garde, and in the current era, there is no way to make such a chemical reaction.

Otherwise, Liu Wei directly made TNT explosives, and what kind of trebuchet, bed crossbows, and then a strong city, dug a tunnel, buried explosives, and sent the soldiers defending the city to see God.

"It's simple, two iron balls hit the ground at the same time." Liu Wei looked at it and said casually.

"Impossible." Before Ma Jun could speak, Huang Yueying shouted, "These two iron balls are not ordinarily big, falling from the same height, it must be the heavy iron ball that lands first." ”

Liu Wei was noncommittal, and turned his head to look at Ma Jun, "Deheng thinks so too?" ”

Seeing the principal's question, Ma Jun looked a little nervous, although he had discussed it with Huang Yueying for a long time, he still said cautiously: "Yijun's thoughts, I'm only afraid of ...... I'm afraid that it will land one after the other. ”

After listening to this, Liu Wei sighed in his heart that he stood on the shoulders of giants, and it was really different.

Changing the topic, Liu Wei was concerned about the construction of the giant catapult, that is, the return cannon of the Yuan army later.

This kind of heavy trebuchet has a miraculous effect on siege, the kind of boulder falling from the sky, the psychological blow to the defenders is huge, and the blow to the city defense is equally deadly.

It's just that although the mechanical principle is the same, the difficulty of making it is several times higher than that of an ordinary trebuchet.

"Headmaster, we've already made two and are preparing for a test launch."

"This cannon has a different name, it's called Hanwei cannon." Liu Wei thought that the return cannon was the name of a foreign tribe, and he was unhappy, so he opened his mouth and changed his name.

The main makers of the Hanwei cannon are Ah Lao Wading and Yi Si Ma Yin, both of whom are believers in the Western Regions, which require a lot of physical and mathematical principles, and now the culture of the Central Plains is focused on poetry and songs, and there is obviously no research on mathematics.

The prosperity of literature can certainly show the elegance of Tang and Song poetry, but the development of mathematics and physics can support the backbone of a nation.

If Liu Wei was to choose one of them, he would not hesitate to choose mathematics, physics and chemistry.

Let the students pay attention to mathematics, physics and chemistry, rather than the light wind of the Wei, Jin, Southern and Northern Dynasties, Liu Wei had a plan in his heart and slowly changed their thinking.

After the Three Kingdoms, the literary style of scholars prevailed, and there was a generation of celebrities like the sage Wang Xizhi, but the whole nation was exaggerated, losing the majesty of the Han Dynasty, and there was no domineering style of the Three Kingdoms.

After the Western Jin Dynasty was destroyed, Wang Dao, the "Merry Prime Minister", took the Jiangshi people as the main body, and the northern and southern scholars jointly assisted the Jin Yuan Emperor Sima Rui.

This group of scholars and doctors who have the merit of the dragon invited the new pavilion to drink, and when they saw the good scenery all over the mountains, they did not sigh that Taizu said 'the rivers and mountains are so delicate', but when everyone was drunk to seven or eight points, they hugged each other and cried in the pavilion, how could such an official be able to defeat the group of savage lions in the north?

Liu Wei's thoughts wandered freely on the drawings full of symbols, and it was not until Huang Yueying shook a few times with a pair of small hands in front of his eyes that he summoned his mind back.
