Blind for five years: Has Cao Wei unified the Three Kingdoms?

In fact, these questions are quite simple.

And it's also fun.

However, the five people of Cao Cao, Cao Ang, Cao Anmin, Cao Xiu, and Dian Wei were more confused than one.

The scene was a little quiet for a while.

It's not as quiet as words.

Five people are you look at me, I look at you, all shake their heads, none of them know.

"Sir, why is that?" Or Dian Wei is honest, if you don't know, you don't know.

Just ask if you don't know.

Ye Qingdao: "It flows eastward because China's terrain is basically high in the west and bottom in the east, plus the influence of the earth's gravity, so it basically flows east."

Water goes low also because of gravity, gravity attracts water to move to the center of the earth, and naturally goes low. In fact, not only water, everything around us is affected by the gravity of the earth, so it all falls. "

"Too because of the rotation of the earth and the revolution around the sun, people on the earth feel that the sun rises from the east every day, in fact, the sun never sets, basically maintains the same distance as us, but because of the line of sight, we can't see it."

Earth's gravity.

What is this again?

By what everything listens to him, all move downward.

The rotation of the Earth.

Orbit the Sun.

It was even more in the clouds and fog, listening to the heavenly book, and the five people were at a loss.

It's too inscrutable.

It's too esoteric.

Cao Ang said: "Sir, why don't the clouds fall, didn't you just say that everything around us is affected by the gravity of the earth and will fall!" "

Ye Qing smiled.

To draw an inference, this is a smart baby.

Ye Qing explained: "Because the water molecules that make up the cloud are very fine particles, these particles are blown up by the wind after they are formed, and the wind speed exceeds the speed of the cloud falling, so from our point of view, we will find that the clouds are floating in the air, because the water molecules that make up the clouds are light in weight and small in size, and a small breeze can lift them up, so the clouds will not fall." "

"Even if it falls, the temperature increases into water vapor in the process of falling, and it begins to float upwards again, and after reaching a certain height, it condenses into clouds when it is cold."

So it is!

The three of Cao Ang were good at accepting this new knowledge.

Cao Cao is different.

Cloud, isn't that something created by the immortals?

The immortal soars into the clouds and sets up the fog, driving it as a walking tool.

How come to Ye Xianren, here it became a water molecule.

Don't...... It was the immortals who did not want to tell Zi Xiu and the others such a truth.

It must be like this, how can this kind of immortal secret technique be made public.

"Then sir, why did we see lightning first and hear thunder!" Cao Xiu also asked.

Ye Qing said, "Because the speed of light is faster than the speed of sound.

The speed of light is about 600,000 li per second, and the speed of sound in the air is 340 meters per second! "

Light is faster than sound.

Dian Wei suddenly seemed to think of something, and interjected: "So sir, when killing, the cold light generated by the halberd will first hit the person's eyes, and then you will hear the sound of the halberd breaking through the air!" "

"..."Cao Cao.

"..."Cao Ang.

"..."Cao Anmin.

"..."Cao Xiu.

Ye Qing was also stunned for a moment, and his eyebrows raised slightly: "You are... A talent! "

Is this canon three a butcher?

"Thank you sir." Dian Wei seemed to have discovered an incredible secret.

When killing people in the future, it is best to plaster the halberd with some ash, so that there will be no cold flickering, and it will be faster to cut off the head.

Am I praising you?

The four of Cao Cao were really uncomfortable, and they lowered their heads one by one and coughed lightly.

"Okay, if you want to ask anything next, you can ask me, as long as I know it, I will try to explain it clearly!" Ye Qing found that the foundation of the three children was very poor and needed to be touched.

Teaching according to aptitude is the right way.

It's up to students to ask questions.

This is rare.

Cao Ang and the three of them couldn't do it, and in the past, the ethnology teachers in the clan all talked about themselves, lectured and then asked a few questions, pouring out half of the private goods in their heads.

Then I left, where is there this kind of link where you ask me to answer, I ask you to answer.

So the three set their sights on Cao Cao.

Cao Cao gave them an affirmative answer.

At this time, Cao Xiu boldly asked: "Sir, I want to ride a horse, I want to learn the skills of horseback quickly, but the horse won't let me ride, is there any way?" "

What a breaking problem this is.

Ye Qing's eyebrows raised lightly, but the one who came did not refuse.

He asked, "Does your horse have no saddle and no pedals?" "

Cao Xiu replied anxiously, "What is a saddle?" What is a horse pedal? "

Sure enough, this is so closed, even the saddle and stirrups do not know, think about the horseshoe is also clear, accidentally get a horse, and then want to tame it, but unfortunately there is no ability to tame a horse.

Ye Qing then explained what a saddle is, what a horse pedal is, and a horseshoe.

And said to Cao Cao: "Boss Cao, you should understand what I mean, you find a blacksmith carpenter and build these things, I believe Cao San will soon be able to learn to ride a horse!" "

Cao Cao was stunned.

Saddle, pedals, horseshoe (horseshoe), the three treasures of this horse.

It's a set of sharp tools.

If it is really effective, it will definitely shorten the speed of the soldiers to control the horse, and they can also free their hands and exert stronger combat effectiveness during the battle.

Cao Cao's whole body was excited.

Cao Xiu was even more excited and wanted to go back to the experiment immediately.

This is one of the three commanders of the future Haw Par Ride.

Born with a keen interest in riding combat.

Seeing that Ye Qing easily solved Cao Xiu's problem.

Cao Ang, Cao Anmin, and Cao Xiu completely obeyed.

At first, I thought that Cao Cao had asked them to worship an old pedant, and he wanted to listen to the way of Confucius and Meng.

As a result, Ye Qing came up with several problems of visions between heaven and earth.

Not only did it open the door to a new world, but it also solved practical problems.

The three are not stupid, and they can be regarded as aristocratic children.

The three treasures in the horse are equipped to the surprise soldiers, and the combat effectiveness of the surprise soldiers can definitely be improved by a large section, so the development of the Cao family is absolutely huge.
