Liang Xiao spoke in great detail, perhaps even the most detailed he had ever explained. Whether there will be such an experience in the future, he can't guarantee it.

Most of them have studied the formula of the refraction theorem derived by Liu Ling, and their understanding is far deeper than that of ordinary people. After seeing those similar scenes through the glass plate, they felt that they really understood. But when they saw that Liang Xiao deduced it through the refraction theorem, they once again realized that they had drawn their conclusions too early.

Compared with Liang Xiao's explanation, their understanding is too coarse and too brief. In Liang Xiao's words, at most it is only qualitative, and there is still a considerable distance from quantitative. It's like being able to understand the principle of refraction, but not yet writing a formula, it's a long way off.

If you use archery as an analogy, this is like the insurmountable distance between ordinary archers and archers like Liang Xiao.

Not only did these guests listen to it with relish and sweetness, but even Liu Ling felt that he had gained a lot. She had worked a lot on the refraction theorem and thought she had stood at the top, but after listening to Liang Xiao, she realized that she had not really understood this theorem.

Liang Xiao spoke for half an hour before he finished his explanation. He took a sip of water, moistened his throat, and looked at the people who could listen attentively, the corners of his mouth slightly raised. "Gentlemen, am I still clear?"

"Clear." Zuo Wu stroked his palms and sighed. "I've heard a lot of people talk about this refraction formula, but none of them are as simple and coherent as Liang Junhou."

Wu was also nodded and praised: "That's right." This is the realm of integration and inference, which is very accessible. ”

Zuo Wu is Liu An's first confidant. Wu was a top advisor who was called Huainan Erdu along with Lei Bei. They praised Liang Xiao for speaking well. Others were even more appreciative.

Liang Xiao raised his eyebrows. "So, you all understand?"

"Understood."

"I understand, I understand, I explain it so clearly, and I don't understand it, it's really stupid."

Liang Xiao turned to look at Liu Qian. Liu Qian also nodded again and again, and was glanced at by Liang Xiao, and his heart suddenly chuckled. There was a sense of foreboding.

"Prince, do you understand?"

Liu Qian looked around, embarrassed. Everybody understands, I don't understand, are you the stupidest one?

Liang Xiao asked, "Is there a problem?" ”

"Uh...... No problem. ”

"Okay, let me ask you a question." Liang Xiao grinned, as if a hunter had seen his prey fall into a trap. He picked up the glass plate, placed it in front of Liu Qian, and slowly rotated it until it reached an approximately horizontal angle. Only then did he ask, "Can the prince still see things through the glass plate?" ”

Liu Qian's face became ugly. He should have seen something on the other side through the glass plate, but now all he saw was a reflection.

What's going on?

Liu Qian looked at Liang Xiao. The face is swollen and red. He could almost guess that this was a pit that Liang Xiao had left for him.

"You...... What do you want? ”

Liang Xiao smiled, smiling very proudly. "I don't want to do anything, I just want to ask the prince to explain why. Why can't you see what's on the other side of the glass plate? ”

Liu Qian opened his mouth and stammered, his eyes were red, and he was almost about to shoot the case. Liang Xiao embarrassed him in front of him for so many years, and he couldn't bear it. But he couldn't really be angry, otherwise he would not only lose the battle, but also lose his grace.

Liu Ling's eyebrows frowned slightly, thoughtful.

Liu An coughed: "Boming, why is this?" ”

Liang Xiao glanced at Liu An and bowed. "I'll leave this question to you. Huainan is full of talents, and if you can write such a big article, someone must be able to solve such a small problem. Gentlemen, offer ugliness, offer ugliness. ”

Everyone was relatively speechless, and there was a dead silence in the hall. Today, the three thousand guests of the Huainan Royal Mansion were all slapped in the face, and they were beaten so that they had no temper at all. The two sides are not at the same level at all, and they still want to embarrass others? It's a shame.

――

At the end of the lecture, Liu Ling and Liang Xiao returned to the back hall. Liu Ling, who had been holding back for a long time, finally had a chance to speak.

"Husband, why are you doing this? Not only did he sweep Brother Wang's face, but even my father couldn't stand it. ”

Liang Xiao was very surprised. "It's just that others don't understand, why do you ask that?"

"Are you...... I hope that my father and the king will be ashamed and courageous, and sink down to study some practical learning? ”

"That's one thing. It is already difficult for your father to make a major breakthrough at the level of the Dao, so he should calm down and study some seemingly trivial techniques, but in fact they are more solid. Taoism is interdependent, and without a solid foundation for art, Taoism is just a castle in the air. That's just one of the reasons, though. ”

Liu Ling's eyes rolled. "Do you still want the court to decide that you and my brother Wang are not on good terms? With my brother's temper, I will definitely be angry when I go back. My sister-in-law is the daughter of Xiu Chengjun and the grandson of the Queen Mother, and in less than a month, all the things that happened here can reach the ears of the Queen Mother. ”

"The key is to reach the ears of the Son of Heaven. I hope that the Son of Heaven thinks that your brother Wang is just a waste, and there is no threat. ”

Liu Ling squinted at Liang Xiao, as if smiling. "In your heart, my brother Wang is probably a waste, right?"

"It doesn't matter what I think, the key is what the Son of Heaven thinks." Liang Xiao put away his smile. "Do you really think that the Son of Heaven can rest assured that Huainan has 3,000 guests? Do you know why the Son of Heaven decided to let Liu Fei go to Northern Xinjiang to participate in the war, and did not let him be the main force, but asked him to contain Zuo Xian's royal department? ”

Liu Ling sighed softly. She was silent for a moment: "So what to do?" ”

"Triage. Those who are indiscriminately driven away, and those with lofty ambitions are recommended to the court, and those who are like-minded with your father and are willing to be loyal to your father, give them a sum of money, and let them travel. The rest talk less and do more. ”

"Ambitious recommended to the imperial court?"

"That's right, recommended to the imperial court. These people are too ambitious, Huainan can't keep them, so it's better to recommend them to the imperial court, and they can still have some affection. It is the time for the imperial court to employ people, and with their abilities, they will soon be able to stand out. They have a firm foothold in the imperial court, and if something happens to Huainan in the future, they can still talk. ”

Liu Ling thought for a moment. "I can understand your good intentions, but I'm afraid my father can't bear it."

"I'm worried about that, too." Liang Xiao shook his head. "I can only mention some general directions, and how to operate depends on your father. Say a thousand, say ten thousand, what can really guarantee safety is strength. If your father can make good use of the wisdom of these people, the court will not dare to act rashly even if he is afraid. I am talking so much just to tell them not to despise these seemingly trivial knowledge, and to put it into practice. ”

He sighed and flicked his fist into the air. "If the strength is enough, who wants to pretend to be a grandson."

Liu Ling laughed. "In that case, why don't you accumulate strength on your own, but give this opportunity to Huainan?"

"You think I don't want to do it myself?" In front of Liu Ling, Liang Xiao had much less scruples, and would say a few rebellious words from time to time. Anyway, everyone is not a submissive minister, and now they sleep in the same bed again, life and death together. "I don't have the foundation of Huainan, and I am closely watched by the Son of Heaven, so I have to repair the plank road openly and secretly cross Chencang. I hope your father will not let me down. ”

Liu Ling chuckled: "So, I, Huainan, have picked up a big bargain, and the little woman has thanked Liang Junhou for this." ”

"How thanks?" Liang Xiao blinked. "Such a big gift, you can't simply thank you."

Liu Ling's eyebrows were full of spring, and with a gentle push, he pushed Liang Xiao to the side of the bed, and shouted: "Beta, Xia, don't you come in yet, are you waiting for me to invite?" ”

Beta and Thea walked in with red faces and closed the door. Liang Xiao was startled when he saw it. "What do you want to do?"

"It's nothing, I recently taught them a set of channeling techniques, and I'm going to practice with my husband." Liu Ling raised his eyebrows, stretched out the tip of his pink tongue, and slid over his plump lips. "Husband, you have to show your skills and don't let us down."

Looking at the three beauties with their loose clothes untied, Liang Xiao's tail bones were tingling, and half of his body was already crisp.

――

Liu Qian returned to his small courtyard, and as soon as he entered the door, he couldn't help but scold, startling the crown princess who came up. The crown princess asked timidly, "Your Highness, what's wrong?" ”

"Liang Xiao, that pariah, dared to be rude to me." Liu Qian stretched out his hand to push the princess away, strode into the house, crossed his hands on his waist, turned back and forth twice, saw a pen and ink book on the case, and a silk book that looked like a calculation problem, and asked, "What is this?" ”

"The question from the capital is said to be ...... by my sister-in-law Liang Xiao"

As soon as he heard the word Liang Xiao, Liu Qian was even more angry, rushed up, wiped all the things on the case on the ground, and felt angry, and overturned the case again. The pen and ink were scattered all over the ground, and the princess was so frightened that she lost her face and shrank aside.

"Women's families, husbands and children are enough, what books to read, what problems to solve?" Liu Qian glared at the crown princess. "Do you want to learn from my sister? Hmph, she married Liang Xiao, a pariah, and she will not end well in the future. ”

The crown princess heard the meaning. "Liang Xiao messed with you?"

"It's not just to provoke me." Liu Qian gritted his teeth. "He simply didn't take me as a prince seriously. He thinks that I Huainan is a poor relative, can I let him insult him at will? This pariah, it's just damned, damned, damned! ”

A hint of joy flashed in the crown princess's eyes. She came over, flattered, and accompanied Liu Qian to turn the phoenix upside down. Liu Qian was exhausted and fell asleep. But the crown princess got up in her clothes, called two maids to marry, and asked them to go out to inquire about the lectures.

The maid went out, and the princess sat in front of the repacked bookcase, took out the silk book from the capital, and her eyebrows trembled slightly.

"This man...... It's a mystery. It's smart and smart enough to worry the Son of Heaven, and it's so confused that it makes people cry and laugh. It's really rare to be so rude to the prince just after marrying the prince. ”――
