In April of the third year of Hongwu (1370), Xu Da, who had already dealt with the endgame in Shaanxi, had completely covered his hands, and was completely passionate and energetic, led his troops into Gansu.

This time, Zhu Yuanzhang, who knew that he had encountered hard stubble, was indeed not stingy, and he gave Xu Da 400,000 soldiers and horses.

Knowing that Wang Baobao, a bastard, is a character that is not easy to mess with, Xu Da also seems to know that Lanzhou is a trap, a fire pit waiting for him to jump into and then make himself unrecoverable, so he is very knowledgeable and did not go to this troubled water.

Before entering Gansu, he seemed to have set the course of action and also chose the venue for the finals.

The name of this site is: Shen Eryu (in Dingxi).

Xu Da thinks that Wang Baobao is a bastard who doesn't remember to eat.

The same play can be played on him several more times.

As the saying goes, isn't it?

Again and again, not again and again, again and again.

I don't believe in it.

I'm going to play this again and again, and see how you Wang Baobao takes it.

Therefore, Xu Da did not directly lead the troops to rescue Lanzhou, but led the soldiers and horses to surround Dingxi.

It was roughly the same as the last time he fought with Wang Baobao in Shanxi.

Didn't you want to hit my Dadu last time, then I'll go to your back and hit your Taiyuan.

This time he played the same way.

Since you beat my Lanzhou, then I will beat your old nest Dingxi.

See how you parry.

With the lessons learned from Taiyuan last time, Wang Baobao also learned to be obedient, as his strategic base in Dingxi, this time Wang Baobao did not pull all the soldiers and horses out to besiege Lanzhou.

Instead, a large number of people were left to garrison here.

When he heard from his subordinates that there were a number of soldiers and horses who surrounded their base areas, Wang Baobao, who was recruiting flies to feed mosquitoes on the outskirts of Lanzhou, panicked first.

He knew that it was Xu Da who came.

The team led by Xu Da will always come.

It's just that what he didn't expect was that the trap he carefully designed didn't play any role, and it became a fart ornament.

Looking at the trap he had designed with all his heart, Wang Baobao could only sigh gloomily.

Xu Da, he is really a master!

What a great opportunity Lanzhou is here, just lost in vain.

It's a pity, it's a pity!

Looking at the city wall of Lanzhou not far away, Wang Baobao was unwilling.

Since you won't let me have a good time, then I will definitely not let you deflated people live comfortably.

His approach was to leave a group of men and horses to continue to besiege Lanzhou, and he himself sent a part of his troops and horses to rush to Dingxi.

When Wang Baobao arrived at Lane Xian, the two armies met for the first time.

When two friends who haven't seen each other for a long time suddenly meet, they must be polite to each other.

So the two sides first knocked briefly in the lane.

In the end, the two sides suffered losses from each other, and Wang Baobao temporarily retired to Shen Eryu.

Shen Eryu, this address now does not know its specific location, from the history books we only know that it is probably in Dingxi, the specific address is really not found.

We can only guess.

That is, Meng.

If I'm right, that's my luck, and if it's wrong, don't hit me.

I'm shameless, but I'm afraid of pain.

From the literal meaning, the place of Shen'eryu should be a deep depression, only the road in front is feasible, and the back and left and right should be surrounded by mountains, which is undoubtedly a powerful terrain.

Having been entrenched in Gansu for several years, Wang Baobao, who had already conducted an in-depth analysis of the topography of Gansu, must have studied the terrain before he came.

So he chose Shen Eryu as his temporary retreat.

It stands to reason that this place is really good, there is no need to fortify on the left and right, just keep an eye on the road in front of you, and you don't need to be afraid that there will be enemies on the left and right to stab you in your hinterland.

Wang Baobao also seems to have taken a fancy to this, so he chose this place.

But he misestimated Xu Da's ability.

He didn't know that Xu Da also fell in love with this place, and he happened to be in Shen'eryu, a terrain that had only one exit like a stuffy gourd.

When Wang Baobao settled down in Shen Eryu, what surprised him was that Xu Da's troops and horses were also stationed not far from Shen Eryu, and there was only a ditch between the two armies.

Xu Da, who was stationed, didn't seem to be in a hurry to find Wang Baobao to fight.

Instead, they began to burn fires, cook, set up camp, and prepared for a long-term garrison.

Not only that, Xu Da also did one thing.

Chopping trees, cutting trees.

Since being stationed in Shen Eryu, Xu Da has started his civil engineering and construction projects, and has embarked on his almost legendary internship in construction engineering.

At his request, the Ming army did nothing else, except for digging pits and cooking, they were busy with one thing, that is, making fences.

Lots and lots of wooden fences.

A wooden fence more than one meter high was made.

At this time, Wang Baobao, who didn't know the real intentions of Xu Da's political opponent, was first circled.

He didn't know what the other party was going to do, but Wang Baobao knew that Xu Da, who had a bad stomach, must not be holding back any good fart.

What kind of plane?

Xu Da, this bastard, what kind of bad fart is he holding back?

He wanted to ask Xu Da for these questions in the air, but no one answered him.

When Xu Dasheng had been working for several days and was fully formed, basically in line with his original military settings, Xu Da gradually stopped the work on the hands of the soldiers.

Xu Da, who was basically ready, began his layout.

He first divided the soldiers and horses into three waves.

A group of people rested.

A group of people do the work.

Another group of people sent small units to harass the enemy in a small area.

The task of this group of people is not very large, and the main work is to set up fences.

At Xu Da's request, a fence was set up at intervals.

The tasks of the two sides need to be tacitly coordinated, and after the first wave of people harassing the enemy, the enemy will definitely withdraw its troops, and then it is time to set up the second wave of the fence.

You take advantage of their territory, set up fences, and fix them.

Then it gradually moved forward.

When one group of people is tired, then they will first withdraw and rest, and then replace the third group of people who are sleeping to continue working.

Rotate and take sides, with no one participating.

No one was idle.

At this time, Wang Baobao, who was stationed in Shen Eryu, finally understood.

It turns out that you Xu Da sulked and made such a loud fart for a long time, you are really poisonous.

It's also lacking.

By doing so, you're gradually shrinking my range of movement and suppressing my area of activity.

My territory is getting narrower and smaller little by little as your fence progresses.

And more importantly, your fence is so high that my cavalry can't do anything at all.

My war horses can jump high, but after all, they are war horses, not rabbits, and if you set up so many fences, they beasts can jump over!

You're really ruthless.

My hole card and my trump card are cavalry, if the cavalry doesn't work, then it's a fart!

You choked me by seven inches with this move.

Just when Wang Baobao didn't know how to deal with it, Xu Da, as an opponent, also found that he had done almost enough civil engineering for his own use, and after the progress of the parallel advance slowed down significantly, he stopped his pace of continuing to move forward.

At this time, Xu Da did not let the soldiers idle.

It's a new way to play.

This kind of play seems to have been inherited from Zhu Yuanzhang, because as early as many years ago, Boss Zhu played the same trick, but at that time, Zhu Yuanzhang called a group of women's army, a group of women who danced and danced without considering the consequences, and the choice was completely shrewd scolding the street.

When Zhu Yuanzhang told Xu Da about this extremely simple but quite effective way to play, Xu Da, who was familiar with soldiers and horses as a general, learned from this strategic experience.

Not only that, but he also carried out a series of improvements and upgrades on this basis.
