If Li Er wants to send troops to Gaochang, he must first solve Xue Yantuo.

So even though he told Li Zhong at the beginning of the year that he had such an idea, this idea was finally delayed until the end of the year.

As soon as Li Jing heard that he was going to fight Gaochang at home, he immediately entered the palace and asked to send him.

Li Er said to Li Jing: "No need, I have already decided to let Hou Junji go with Xue Wanche this time." ”

Li Jing said: "Is it Li Chong's idea?" ”

Li Er: "No, it's my own idea. ”

Li Jing nodded.

Li Er: "How did the King of Jin and Li Chong's four sons learn war?" ”

Li Jing said: "Back to Your Majesty, you can learn well." Especially Li Chong's second son, Li Youran, can discuss the art of war with his ministers. ”

Five people came out of one, and this luck is not low.

Li Jing said again: "It's just ...... Wouldn't it be good to let King Jin also learn the art of war? The minister heard some rumors. ”

Li Er thought about it, let's explain, "I plan to divide the feud to the outside world, and the King of Jin will go to other places to be the king in the future, as for the specific place, it is still uncertain." ”

Li Jing: "External separation? ”

Li Er: "It's just like the Zhou Dynasty divided the princes, but the place where the feudal was divided is not in the current Tang Dynasty." It's outside of Datang. ”

Li Jing's mind flashed through countless pieces of land in an instant.

Of course, even then, he wasn't sure exactly where.

But as you can imagine, this must be tough.

Because except for Datang, there is almost no good place outside.

Could it be Gaochang?

Western regions?

Li Jing: "That minister understands. ”

……

And the princess's mansion is here.

Li Chong is also holding his fifth son who was born not long ago.

Said:

"Later...... You just call it 'Li Tian'. If it is reborn, it will be called Li Tang. ”

Hearing Li Chong say rebirth, Li Lizhi suddenly felt a little pain under her.

But after all, it was the first son, so even if it hurt, she still treated it as a treasure and gently hugged it on the bed.

At the same time, the Academy of Sciences ......

This year, Li Chong also added a lot of manpower to the Academy of Sciences, so that the number of craftsmen and apprentices together came to one hundred and fifty.

Because Li Chong felt that it was still a little slow before.

And......

Something like a steam tractor is certainly not too much.

To this end......

Li Chong also divided 150 people into 10 groups.

Let each group make a steam tractor to come out.

As for the first steam tractor, it is now also in the final stages of completion.

Just wait for when, when they're done, and see if they can plow the ground.

Feel......

It should be ok.

After all, the cylinder this time is much larger than the previous one.

It feels like the horsepower is much bigger too.

On this day, when Li Chong returned Li Tian to Li Liqing, craftsmen from the Academy of Sciences came directly to the princess's mansion to report to Li Chong.

"Done?" Li Zhong asked.

"It's done! Just wait for you to pass, Dean. ”

Li Chong went back to the house and said to Li Liqing, and then followed the craftsman to the outside.

Due to the large size of the steam tractor and the ......

The doorway to the Academy of Sciences is too small.

So......

In order to get it in one step, Li Chong also asked the craftsman to directly move everything to Li Er's forbidden garden for assembly.

After the assembly is completed, you can directly cultivate the land in the Forbidden Garden.

All I can say is......

Under the control of the craftsmen, the steam tractor was made for almost two years, and finally it moved slowly.

And......

This power did not disappoint Li Chong, and at one time, this steam tractor can pull five plows.

And the whining whistle here also attracted the attention of many slaves and maids of Sinong Temple.

In fact, they had noticed these craftsmen for a long time, and this strange monster.

It's just that......

What they didn't expect was that this thing would move slowly on its own!

This is simply going to ruin their three views.

Time......

This hard-working ancient slave and maid, together with a big black guy, form a contrasting painting.

The craftsmen were also excited to see this.

In particular, some craftsmen can't help but run forward to pick up the soil that has just been ploughed.

I couldn't help but sniff the fragrance of the earth.

After sniffing, he took the dirt back and gave it to Li Chong.

"Dean, look!"

Li Zhong pressed his excited heart, in fact, he knew very well that he had done it now, but the follow-up had to look at whether it was not easy to damage and the failure rate.

Therefore......

Let them plow for a few days.

Meanwhile......

After thinking about it, let's talk to Li Er.

Let Li Er be interested, just take a look.

So the next day.

Li Er came with a hundred horsemen, as well as the eldest grandson queen.

The two of them watched a thing weighing at least ten or twenty tons emitting black smoke all the way in the ground, and it could be said that this thing was indeed a little shocking.

This is what Li Chong once said at the beginning, a machine that can be used to plow the land without oxen.

"Your Majesty, this is ......"

Empress Eldest Sun has seen such a big guy there.

Li Er was still shocked to tell the truth.

"Li Chong, come and explain it to the queen."

Li Chong said: "This is a steam engine tractor. The main thing is to use it for farming. Of course, it can also be used for other things, for example, to pull some goods, which should also be possible. ”

Of course, Empress Eldest Sun knew that this thing could pull goods.

What Empress Eldest Sun actually wanted to ask was......

Who could make such a thing?

"Li Chong made this thing?"

Li Chong also said modestly: "Actually, the minister only provided a little idea, mainly due to the merits of the craftsmen of the Academy of Sciences. ”

Empress Eldest Sun said, "Li Chong, are you really human?" ”

"Forehead ......"

That's right!

Of course you are human!

If he is not human, how can he let Li Lizhi have a child.

Li Chong could only explain: "Actually...... The principle of this thing is very simple, the queen just doesn't know the truth in it, so at first glance, she feels that this is not something that can be found in the world. As long as the queen understands the truth in this, she will not feel how mysterious this is. ”

That's how to say it.

But!

It's still a little hard to believe.

And Baiqi is also very shocking.

Li Zhong looked at Empress Changsun's unacceptable expression, and next, he also found a place to explain the principle of this thing to the other party in person.

Under Li Chong's careful and careful explanation, Empress Changsun only then knew what was going on.

In fact......

It is through various gears and connecting rods that the power that can push the kettle into the power of this behemoth, as for why there is black smoke, it is because coal is burned.

After a brief lesson, Empress Eldest Sun understood the principle of this thing.

But I understand!

But......

It still shocked her!

"Won't there be no need to plough cattle in the future?"
