Lu Heng and Li Mingyu together took Wu Zhao into the study with ease.

This place has now been cleaned, and in just one or two days, Lu Tongren even got him a higher table according to Lu Heng's habits.

It's a tall table that hasn't been seen yet.

Lu Heng walked to the table.

He originally wanted to reach out for the brush, but after thinking about it, he couldn't hold it at all, so he had to look at Li Mingyu.

"Yu'er, I said, can you write it?"

Li Mingyu was stunned, and he couldn't hold back his laughter.

As Lu Heng's wife, she naturally knows how ugly Lu Heng's words are.

persuaded him to practice calligraphy before, Lu Heng also said that he had no official position, and he didn't plan to be an official, so he didn't need to write anything in person, so he refused righteously.

Now it's good to pour.

It's coming, and suddenly I'm going to be a gentleman!

She coughed softly, stifling back the sound that was about to burst into laughter.

"This is your student, why do you want me to write it?"

"If you don't give some benefits, I won't agree!"

Li Mingyu originally just wanted to tease him.

But what she didn't expect was that Lu Heng pondered for two seconds after hearing this, and then nodded with a serious face.

"Makes sense."

"Yu'er, then you can help me go to the kitchen to find some carbon!"

Li Mingyu: ???

Although he didn't understand what Lu Heng wanted to do, Li Mingyu still went to the kitchen very obediently.

After she left, only Lu Heng and Wu Zhao were left in the study.

Wu Zhao hesitated and asked:

"I'm ...... now I'm supposed to call you sir, right? ”

Lu Heng smiled and nodded:

"You name it, you name it. If you feel that you are not used to calling me sir, you can also call me Brother Lu. ”

Wu Zhao thought for a while:

"Let's call you sir."

"What are you going to teach me, sir?"

"You said before that if you learn mathematics, physics and chemistry well, you will not be afraid to go all over the world......"

"What is this mathematics, physics and chemistry?"

Lu Heng raised his eyebrows.

He casually opened the window, and the window was facing a centuries-old tree, which seemed to be a pear tree.

Pointing to the tree, Lu Heng asked:

"That pear tree, although it is not yet the season to bear fruit, will it fall on its own if no one picks it when it is ripe and falls?"

Wu Zhao nodded.

Lu Heng continued to ask:

"Then have you ever wondered why it fell?"

"If the fruit is too big for the branches to bear its weight, then why did it fall down?"

"Why can't it float up into the sky, to the left and right?"

This time, Wu Zhao didn't continue to nod.

She was stunned for a long time before she stammered:

"This ...... This has been the case for thousands of years......"

Lu Heng raised his hand to interrupt:

"I didn't ask how long it had been like this."

"It's the same with any other fruit that pears are exchanged."

"What I'm asking is, why."

Wu Zhao was speechless.

Lu Heng laughed.

"That's what mathematics, physics and chemistry are going to learn."

"What I want to teach is the truth of how everything works in this world, and know what it is, and why it is."

"Why are there suns, moons and stars, why are rivers flowing into the sea, why do you jump up and fall to the ground again, why are there wind, rain, thunder and lightning?"

"These are all traceable."

"If you can learn it, or even learn better than me, then you can even use the principles to break free from these shackles and fly into the sky!"

said a word, Wu Zhao's eyes were full of brilliance.

More than shock.

She could see that the young gentleman in front of her was extremely confident when he said those words.

It's like...... He can do it himself, or he's seen anyone do it.

Wu Zhao couldn't help muttering:

"Can this really be done......

Right now.

There was a creak and the door was pushed open.

Li Mingyu, who ran to the kitchen to get carbon for Lu Heng, came back.

She looked at the two people sitting opposite each other in the study, feeling this somewhat strange atmosphere and a little puzzled.

"What are you talking about?"

Li Mingyu walked over and handed the carbon to Lu Heng:

"Here's the carbon you want, take it."

"I haven't had time to ask you yet, why do you want this?"

Lu Heng took the piece of carbon, took out the dagger he carried in his arms, and began to sharpen it.

The corners of Li Mingyu's mouth twitched at this action.

She patted her husband on the shoulder with some fire:

"The dagger I gave you, and you are so bad?"

Lu Heng's hippie smile:

"You'll know what I'm going to do later!"

He skillfully split the mass of carbon into several strips, and then sharpened the two ends.

After being busy for a while, Lu Heng symbolically patted his blackened hand.

"Watch the husband show his strength!"

Lu Heng pulled a piece of fine rice paper and began to scribble on it.

Next to him, Li Mingyu and Wu Zhao's eyes gradually widened with his movements.

It was a long time.

The rice paper was already full of messy handwriting, and I couldn't read it.

But there is a ...... A special aesthetic?

Lu Heng almost used the pile of charcoal pens he had just sharpened before he finished writing what he wanted to write.

That's a whole sheet of formulas.

"That's what I'm going to teach you."

Lu Heng wiped his hands with a wet handkerchief, and raised his eyes to look at Wu Zhao:

"I know you definitely can't understand it now, but these things, you can understand them as you learn them."

"Come on, come on, teach you the simplest first-"

"Arabic numerals!"

………………

In the courtyard outside the study.

Lu Tongren, who had been busy all morning, stopped what he was doing and looked at his wife.

"Daughter-in-law, you said that this kid has only been in Luoyang for a long time, and he brought back a girl......"

"And it's with Gong, ah no, Mingyu, brought back with Mingyu."

"What's going on with him?"

Xiao Shi couldn't help but roll his eyes when he heard the meaning of his words.

Isn't this just trying to ask, is Lu Heng looking for an outer room?

"Don't talk about calves, if he really has two hearts, Mingyu can agree, can Your Majesty still agree?"

"If you want me to say, I guess Heng'er really has something serious to ask that girl."

"With his temper, let alone in Luoyang, even if he goes to Jiangnan, he will do something."

As he spoke, Xiao Shi also pouted outside the door:

"Wasn't that one yesterday also worried that he would cause trouble, so he came to our house?"

After hearing this, Lu Tongren felt that this was indeed the case.

His son knows it in his own heart.

As far as Lu Heng's virtue is concerned, he almost bombarded the city gate in Chang'an, and was hunted down and killed because he provoked the family.

If you don't move your brains to Luoyang, they will all wonder if this son is fake!

The couple was discussing.

A figure suddenly appeared in the wing room at the back of the courtyard.

Sun Simiao walked out slowly and asked:

"Where did that kid Lu Heng go?"
