"alert!"

"All members are on guard!"

“…”

horrible.

He didn't come early or late, but he came when he was about to go down the official road. On the spot, Li Junxian got down and quickly arranged defenses, allowing Li Er and Changle to retreat.

Li Er was also shocked.

What's the thing, so loud?

Is that a thunderbolt beast?

And it looked so strange that even the horse sitting down was a little scared and was restless with a loud sniff.

But if you want to withdraw, it won't be.

Because the thing is not fast, although it is amazing, it seems that no matter how dangerous it is, it doesn't seem to be.

Besides, it was driven by the village, and there were many people following behind it. He didn't have to think about it, and he must have a new thing.

But this thing is different from those before. It is tall and mighty, whether it is watches or street lights, it is hard to see it.

When I looked closer, I found that there was someone inside, and it seemed like it was Chen Yuan's guy.

Li Junxian also quietly breathed a sigh of relief at this moment.

Damn, I'm so scared!

I thought it was, but Chen Yuan was still there for a long time.

But then again, is this really appropriate?

In this Lishan Mountain, there are many towers, temples, more Han tombs and imperial tombs. If you are so noisy, aren’t you afraid that emperors of all generations will bring up coffin boards to cause trouble for you?

Of course, this can only be said in my heart.

At present, not to mention that you can’t talk nonsense, even if you are on guard, you cannot completely let go.

Li Er was very excited. Seeing the thing getting closer and closer, the voice became louder and louder, he couldn't help but ask Changle with a smile: "Girl, have you seen this thing?"

"No." Changle shook his head and thought to himself that I have never seen this before, but I have seen a plane.

Super big and super big plane.

At this time, Chen Yuan also saw Li Er and his party, so he simply drove to this side, waved and greeted him loudly: "..."

Well, I can't hear what I'm talking about.

The sound was covered by the huge roar, and I could only see the waves and talking.

Li Junxian couldn't help but become nervous again.

Because the closer the sound is, the louder the roar is, deafening.

Then the body shape, sense of strength, and the visual impact and pressure brought by the thing are getting stronger and stronger.

There is a great momentum of a thousand troops.

So much so that he couldn't help but wonder, is this thing a war beast?

This thing needs to be opened on the battlefield, and your forehead will be so loud that your voice will scare the enemy!

Li Er waved the whip directly and rode out, scaring a group of people to the point of being so scared that they had to keep up with them.

Not long after, the two armies met, and Chen Yuan was also very stable. Seeing a group of people riding on horseback, he stopped early and then turned off the fire.

Li Er did not stop, but rode his horse curiously and turned around in circles.

After stopping, Chen Yuan smiled and asked, "Brother Qin, my horse is not worse than the good horse under Brother Qin?"

Li Er was still observing and nodded repeatedly when he heard this: "A good horse, with square head and big ears, and his body as hard as iron. His voice was like thunder. No one dared to approach humans and beasts, but he ran a little slower."

After saying that, he suddenly changed his mind: "My brother can sell this horse, so why not offer a price!"

As soon as he said this, Changle covered his mouth and laughed on the spot.

Chen Yuan laughed: "That won't work. It's not that I don't want to sell it, but that you can't support this thing, Brother Qin."

"Why is this?" Li Er was excited.

In fact, he vaguely understood that this was not something he could play with, because this big guy looked too big and it was difficult to understand that it was not much lower than that of watches and solar street lights.

But he just likes it.

This doesn't prevent him from liking it.

Especially when Chen Yuan compared the competition with a good horse, he wanted to have it even more, want to drive to the streets of Chang'an City and to the battlefield.

That must be very awesome.

That must feel very good.

Chen Yuan smiled and explained: "Because this thing doesn't eat grass, it drinks oil."

"Oil?" He had no idea at first, and suddenly the flame of hope in Li Er's heart ignited again.

Chen Yuan smiled: "Don't get me wrong, it's not vegetable oil or lard, it's diesel.

Diesel is not oil for diesel refining. If we want to make diesel, with the current level of our Tang Dynasty, we may have to work hard.

But if you save enough oil, you can let Brother Qin go and play. I saw the plow behind you. This thing is getting too old, and each car is full of 100 cows!"

"So, is this thing used to cultivate the land?" Li Er was immediately confused again.

Although he also saw that there were many behind him, as if they were plows, he never thought that such a tall and mighty thing was used to cultivate the land!

This is too useless!

Chen Yuan said, "Yes, this thing is used to cultivate land. In my hometown, it is called a rotary tiller."

Yu Luo shouted, "Okay, let go, watch my performance, I am a novice, not an old driver, if something happens, I will not be responsible."

After saying that, he ignited the fire again, rumbling, and the terrifying roar seemed much stronger than before.

Such a giant creature, with so many sharp and sharp plowshares behind him, as brave as Li Er, did not dare to grab his edge lightly, and he quickly retreated when he saw this.

In the back line of sight, the rotary tiller turned a corner, then lowered the hanging plowshare and started running.

Very magical.

Although I still feel that such a mighty thing is a bit in awe of using it to cultivate the land, the battlefield is its real destination, but I have to admit that this efficiency is far from comparable to that of oxen.

The key is that it is still beautiful when plowed out.

Just the row of plows and rotary tillers ran, and under the guidance, it was like a dragon turning over, and the soil was rushing up one after another. At first glance, it was neat and enjoyed.

When the plow was lifted, the knife holder was placed, and then running again, even the rake was saved, and all the large pieces of soil were crushed.

Only then did I realize that this thing seems to be very good for plowing land, because it is plowing fast and good. If it is used, it needs to be plowed more land and more grain?

Moreover, no one said that those who cultivate land cannot go to the battlefield!

Isn’t this what it is to farm when you are free and go to the battlefield when you need it?

This is how the soldiers of each prefecture are.

Therefore, the heart that longs for possession becomes more and more hot and hot.

So I watched it for a long time.

As soon as Chen Yuan turned off the fire and stopped, he couldn't wait to ask: "Brother, is this rotary tiller also a calculation?"

Chen Yuan was stunned for a moment and soon laughed: "Yes, it's essentially a calculation. If it shows it, it should be considered physics!"

"physics?"

Fresh.

Haven't heard of it.

It sounds like I understand, but I don't understand it very much.

Chen Yuan got off the rotary tiller, took the water handed over by Yongjia and took a sip: "Physics, literal meaning, the principle of things, the principle of everything.

The end of physics is mathematics, but compared to mathematics, physics can explain the world more intuitively.

For example, why there is wind, why it rains, etc., many things, even if you don’t know how to calculate, can be explained by physics.”
