As we all know, the base edge of the pyramid is a square and its four sides are isosceles triangles, which is conducive to calculations.

The reason why it is measured when the height is as long as the shadow is because the sunlight is shining at a forty-five degrees, and geometric knowledge can be used to form an isosceles right-angle triangle for easy calculation.

At this time, you only need to measure the length of the shadow to calculate the height of the pyramid.

Actually, this is a geometry problem in junior high school.

In ancient times, without advanced surveying and mapping technology, it was difficult to measure the height of the pyramid. Li Longji's wonderfulness lies in the fact that he used sunlight to form an isosceles right-angle triangle and used geometric knowledge to solve problems.

Since its construction, how high the pyramid is has been a subject of research. It was not until nine hundred years later that a wise man used this method to calculate it, which shows how difficult it is.

Wu Zetian and the others got into a misunderstanding from the beginning, thinking that they would use some special tools to measure, but no one thought they could use the sunshine.

Until Li Longji asked Mulagu to measure the height and measure the length of the shadow, Di Renjie, Zhang Shuo, Song Jing, and Tai Students would understand.

With the tips from Di Renjie and others, Wu Zetian also figured it out. After her patient reminder, most of the ministers also understood it. They admired Li Longji and praised it in unison.

For a moment, the romance sounded like thunder.

Li Longji can also deserve this praise.

If Li Longji hadn't solved this problem, God knew how embarrassed he would have been. That would be a big joke, and no one's face looked good.

"It's really solved?" Li Dan was dizzy.

"We finally don't have to suffer such severe punishment." Wu Sansi and Wu Chengsi looked at each other and sighed.

Li Longji solved this problem, which was like saving the two of them. If no one could solve this problem and lose all his face, Wu Zetian would be angry, and that would be the relatives. Although they were highly valued and trusted by Wu Zetian, they would not have good results and would have to escape even if they did not die.

Now that Li Longji has solved this problem, they will also be punished, but it is much lighter.

Li Longji was timid and walked towards an unexpected place, as if he was about to be beheaded, and asked weakly: "Your Majesty, you are..."

Seeing his appearance, Wu Zetian was amused and laughed. He held Li Longji's hand and said with a smile: "Grandma is praising you! You solved this problem, but you have made a big face and my grandmother is happy."

Wu Zetian was accurate in Li Longji's meridians. Once this kid became proud, he would be endless and he had to block his mouth first.

"Oh." Sure enough, when Wu Zetian praised, Li Longji just said oh, looking relieved, and there was no more of the following.

"Sanlang, what reward do you want?" Wu Zetian was very generous today and waved his hand proudly, saying, "What do you want? First and second grades? As long as you like it, my grandmother will give it to you."

"First and second grade?"

"Select an official?"

The ministers heard it and all their eyes fell from the ground. Wu Zetian was too generous.

However, after thinking about it, Li Longji is really worth the price.

If this matter is related to the majesty of the court, if it cannot be solved, it will be ridiculed by all countries, and that will be too disgraceful.

"A lucky boy!" Wu Sansi and Wu Chengsi were very unhappy.

"I want to choose an official again? Which official should Sanlang choose?" Li Dan glanced at Wu Sansi and Wu Chengsi with some anticipation.

Last time, Li Longji chose a General Jinwu, slapped Wu Sansi and Wu Chengsi in the face, weakening their power. This time, Li Longji would not miss such a good opportunity. Wu Sansi and Wu Chengsi had a chance.

"The King of Chu will definitely choose an official who is very suitable for dealing with the Wu clan this time." The ministers also thought so.

"Your Majesty, what are you saying?" However, Li Longji's answer was unexpected, and he shook his head: "I am doing my best to be filial and not an official."

"Yes." Everyone, including Wu Zetian, Wu Sansi, and Wu Chengsi, was very surprised.

This is not Li Longji's style. He is the kind of person who needs to make good use of the opportunity when he has the opportunity. It is really surprising that he doesn't make use of such a good opportunity.

"Retreat as advance." Some ministers speculated.

This kind of speculation is the most consistent with Li Longji's personality.

"I really don't want it?" Wu Zetian was very surprised.

"No." Li Longji shook his head, and said very confidently: "Grandmother, grandson is young and cannot go to the battlefield to kill the enemy. He can only solve the problem. How can he be an official in such a small matter? He just needs to worry and solve the problem."

He heard that he really didn't want to be an official. Wu Zetian was very happy, smiling with his eyes wide open, smiling happily, stroking Li Longji's hair, and looking doting, saying, "Good grandson! Good grandson!"

Which grandma doesn’t like her grandson to speak like this?

Wu Zetian is a strong woman and a queen, and she is no exception.

"No, he's making trouble?" Di Renjie always felt something was wrong.

In fact, Di Renjie was wrong. Li Longji really didn't plan to get benefits this time. He thought: "Now, I have arranged everything in the gods almost. Even there are spies in the palace. What do I want to do? Why would I let Wu Zetian 'owe me a favor? At that time, I ask for my order to go to the border and she will take more care of me. By then, it will be more convenient for me to cultivate power."

After Li Longji's efforts, his power in Luoyang has begun to show its scale. He has already gained a lot of fame among court officials. It is time to prepare for the military achievements and power to go to the border.

If Wu Zetian "owes" him a favor, then Wu Zetian will take special care of him, and it will be more convenient for him to act.

"Grandmother, look, does this face look good?" Li Longji changed the subject and pointed to Muragu, attacking Wu Zetiandao.

"It looks good! It's so good! This is the best look my grandmother has seen in her life!" Wu Zetian immediately laughed at Muragu.

At this time, Mulagu's face looked extremely ugly, with cold sweat on his head and a look of shame.

These days, Muragu is extremely proud, but today he has a bad face. Wu Zetian sees it, how can he not be happy?

"What a wonderful face!" The ministers were also happy and burst into laughter in unison.

"Dashi deserves to have a territory of thousands of miles, and his face is so wonderful!"

"What happened to you? Are you sick? But you are not accustomed to the local environment?"

"If you are sick, you can find the King of Chu. The King of Chu can cure all kinds of dissatisfaction, oral dissatisfaction, oral dissatisfaction, and local conditions, and can cure it."

The ministers surrounded Muragu, constantly ridiculing them and saying all kinds of harmful words.

"Why are there no cracks in the ground?" Mulagu wished there was a crack in the ground and immediately got in.

When Li Longji said that he would come back to solve the problem at noon, he knew it was going to be bad. He wanted to find an excuse to leave, but he held it back for Li Longji. Moreover, he was forced to measure his height and shadow length by Li Longji, which was slapping himself in the mouth. At this time, he was in a very bad mood.

"Is this a problem that only you wise men can solve?" Wu Zetian laughed and said, "Did you see it? The heavenly dynasty is full of talents, and a thirteen-year-old boy can solve such a problem. Is your wise men so smart?"

In modern terms, this is "your wise men are the IQ of children". This is a loud slap, slapping hard on Muragu's face, and his face was twisted.

"Haha!" The ministers saw it, and they were very comfortable, and they all burst into laughter.

The laughter was like a knife, slashing Muragu's heart, and his body was trembling.

"Grandma, is this face wonderful enough? But I can make his face even more wonderful." Li Longji pointed at Muraguda.

"This is easy to deal with. I ordered the warrior in front of the palace to beat him, and his face will look even better." Wu Zetian smiled on his face, but his words were full of murderous intent.

This time, Wu Zetian almost played with it. If she really wanted to play with it, Wu Zetian's face would be greatly lost, and she hated Muragu very much.

When the two countries fought and did not kill the envoys, Wu Zetian would not have killed Mulagu, but could have caused him some hardship.

"Your Majesty is wise!" Muragu suffered a little and was embarrassed. The ministers agreed with this.

"Grandmother, our China is full of wisdom. How can we fight and kill? Let's use wisdom to fight and kill him." Li Longji smiled.

"Wisdom?" Wu Zetian raised his beautiful eyebrows, a little confused.

Although you can vent your anger after hitting Mulagu, you can feel inferior. If you use wisdom to make Mulagu lose all your face, that is the best strategy.

"How to do this?" Wu Zetian asked, aiming at Li Longji.

"Grandma, wait and see." Li Longji waved his right hand and rushed to the duty servant, saying, "Turn out sixty-four shorts."

"How many short?" A sound of surprise sounded, from the mouths of Wu Zetian and his ministers.

Everyone had their eyes widened, looking like they had a problem with their ears.
