It’s a pity that the information is limited now, so he can’t analyze the reasons at all.

Fortunately, he could simulate the life of the fourth brother in half a month.

By then all the truth will be revealed!

And the most important thing is that the fourth emperor's career can probably be started.

Although he had passed many simulations of his children and grandchildren, he also knew very well what happened to the fourth emperor's life.

But the problem is that it is only from the perspective of the bystander.

Perhaps from the perspective of the fourth brother himself, there will be another novel insight.

Anyway, Zhu Di is very much looking forward to this.

[Such a powerful army makes you understand why your fourth brother suppressed the opposition from the court, but still lets you command the army.]

[This makes your heart full of touch. You used to have no good feelings for him, but your fourth brother treated you well without grudges.]

[You swear in your heart that you will never let anyone bully him in your life!]

[Although you also know that no one can bully him in the future, this is the only oath you can say in your heart.]

[At the beginning of the 25th year of Yongle, when the cold winter had not passed yet, you led your army to quickly head towards the border.]

[Maybe it was because your fourth brother once asked the army to ride in a carriage and found inspiration.]

[So now that after the road was repaired into a cement road, almost all armies were equipped with a large number of carriages for supplies and injured soldiers to march.]

[Your army in the northern expedition to the Oirat also has such convenience. In almost a month, the army has reached the end of the road.]

[Even if the carriage cannot head to the grassland because of the absence of the cement road, the road ahead will not be difficult.]

[Under the information provided by the Beizhen Fushi and the Jinyiwei headquarters, the army quickly moved into the heart of the Oirat in less than half a month.]

【This caught Ola off guard directly.】

[When they were about to fight back, they found something desperately.]

[Even if the Ming soldiers did not use artillery fire, just using infantry would be enough to defeat all their cavalry.]

Zhu Di was not surprised by the touching and oath in the third brother's heart in the simulator.

After all, the fourth brother is really good to brothers!

The only thing that surprised him and was a little stunned was the way of marching the Northern Expedition Army.

This is really beyond his imagination!

"March in a carriage, is this a war or a stroll?"

Zhu Di was a little silenced.

Because since ancient times, this seems to be the most comfortable process of the army.

As for the emergence of steam engines in the further future, it is naturally not within his consideration.

After all, it will take decades for the emergence of steam engines.

Carriages are everywhere now!

But Zhu Di also understood.

It is impossible to get a carriage to transport soldiers to the border to fight wars without the fourth brother.

Of course, it is not that the fourth carriage is strange.

This is an ordinary carriage, except for its harder material, there is nothing strange at all.

Although the court had difficulty, it was still possible to equip one or two large armies.

The main reason is that carriages alone cannot make the army move so quickly.

After all, there have been many talented people in China since ancient times, so it is impossible that I have never thought about the issue of transporting soldiers in horse-drawn carriages.

The reason why they did not implement it is because they lacked a critical thing.

Flat and hard official road!

If this is gone.

Hundreds of thousands of troops and tens of thousands of carriages may be able to crush a piece of flat ground into a big pit.

Not to mention marching!

Let’s talk about it if you can move!

But with Lao Si's cement road, all this is different!

Because the army can go straight.

They don't have to worry about falling into mud pits or the roads are uneven.

Even if it is a bit bumpy, as long as you cross this section, there will be a hard road below.

As for the simulator, when Ola was touched, Zhu Di was not surprised.

After all, such a highly morale and well-equipped army.

This kind of crushing situation!

No matter who comes, you will have to be fooled!

Not to mention that the third brother caught them off guard.

The speed of the march is as fast as a divine weapon descending from the sky!

Even Zhu Di suspected that the Ola was still discussing how to resist the Ming Dynasty, but the third brother had already been assholeeded.

After all, more than 100,000 troops crossed a thousand miles in two months, which was simply unimaginable in the past!

"My fourth brother is smart!"

Zhu Di showed a bright smile.

Although he had known some time ago that the fourth brother purchased thousands of carriages so that the guards and the guards of the vassal kings could quickly go to Shuntian.

But the problem is.

The number of soldiers escorting the fourth brother was only about 10,000, and although it took a short time, the most important thing was that the soldiers were tempted by money.

So did Zhu Di think about letting the carriage transport soldiers to fight quickly?

But now the third brother sent troops to the Oirat battle in the simulator made him realize that marching is still possible.

Once the cement road is built, it seems that he can draw elite troops from the various armies in the world to form several large armies.

They were assigned to all parts of the world, and each army was responsible for one or several provinces.

These armies are equipped with specially-built carriages, which are best to accommodate a banner of horses.

This will form several army that can quickly respond to various situations.

In this way, it seems that it can deal with sudden situations in various parts of the world in a timely manner.

"Second, wonderful!"

Thinking of this, Zhu Di almost couldn't help but applaud.

Although this plan was just a preliminary plan in his mind, he didn't even know what the actual situation was.

But this is also a way of thinking. For him, he can’t see or touch it now, and he can’t imagine it?

What's more, who said that this method is not feasible?

[At the end of April of the 25th year of Yongle, your father, who was far away in the capital, passed away with regret before he received the news of your victory.]

[And at this time you are working hard for your father’s wishes.]

[In early June of the 25th year of Yongle, you spent only three months sacrificing thousands of soldiers and finally forced the Ola tribe to change its name.]

[After you take down the last piece of land, you will immediately send good news to the capital without stopping.]

[But what makes you extremely painful is that your good news has just been delivered a few days ago and you received the news from your father's death more than a month ago.]

[This news almost fainted, and you feel that your efforts have never been seen by your father.]

[Maybe he is worried about the danger of leading troops to fight before he dies, rather than the joy of your sure success.]

[You can only return to the capital with your second brother with a sad mood.]

[In September of the 25th year of Yongle, you and your second brother led a large army back to the capital.]

[Your elder brother and fourth brother pulled you to kneel down and bow to your father, and quickly brought him into the tomb.]
