Ma Chong, who replaced Xiao Du as the chief scout, did not dare to neglect, and hurriedly led Zheng Yuanyun to the place where he explored.

Zheng Yuanyun took his own Guard soldiers as guards. In order to avoid Ouyang's strict enforcement and discovering their movements, he even deliberately pulled back, which led him to the main traffic road mentioned by Ma Chong.

The road is very wide and wide. It starts from the inland border of Nantes province and almost crosses the East and West. It divides Nantes province into two parts and runs all the way to the city of ter.

It can be said that if there is no obstacle, through this road, we can send troops from the inland to the three cities of ter, Xili and Ketan as the main city in a very short time.

At the beginning, Zhang Chengwang actually used this road to search for troops as much as possible. Unfortunately, later, he was on the verge of success, which also led to the current situation of empty troops in the cities of Nantes province.

After a big turn, hundreds of elite soldiers such as Zheng Yuanyun and Ma Chong came to this important road.

Looking around, as Ma Chong said, there was no shelter on both sides of the road. The road looked very empty and had a panoramic view.

This is actually easy to understand.

In some war prone areas, the defenders mostly choose to plant some dense forests according to the plan. Of course, these dense forests can be used by both the enemy and ourselves, but as the defenders, they know more about the terrain in the dense forests, and can even make some arrangements in advance to serve as warning or ambush.

But Tianyuan city is really unnecessary here.

In this rear area, the ultimate goal is to transport troops at one time. Is it enough, fast and convenient to plant a dense forest to stop your March?

That's impossible.

Moreover, one side of the road is Tianyuan City, which also has some defensive forces. On the other side is a stream. In addition to transporting troops by land, some support can also be provided by water. In this way, it is even more unnecessary to block your own vision.

Therefore, as Ma Chong said, Zheng Yuanyun observed for a long time and came to the conclusion that there was no ambush on both sides of the road.

Compared with the heavy guard of Tianyuan City, this more important way of transporting troops is unprepared?

Even there are no necessary sentry checkpoints. If you look at them, you can even see a faint shadow of the next city and the river city by city at the far end.

Is this serious?

Zheng Yuanyun frowned. It's strange. It's obviously a trap, isn't it?

But the function of this trap is

Zheng Yuanyun looked up and could clearly see the wall of Tianyuan city from him. As Ma Chong said, one side of Tianyuan city was built against the mountain, so there were only three gates to enter, and a whole circle of walls were expanded around the periphery of the three gates, which strengthened the original Tianyuan city with weak defense ability.

"Do you know how many troops there are in Tianyuan city at the moment?"

After pondering for a moment, Zheng Yuanyun asked.

"This..."

Ma Chong Hanyan said, "my Lord, they have played a good role in Tibetan soldiers. At present, it is impossible to infer how many troops there are in Tianyuan city."

Hearing this, Zheng Yuanyun was dissatisfied.

For so long, even before coming, the principle of Scouting first has been implemented. Therefore, the scouting team of Ma Chong and others even arrived long before Zheng Yuanyun's large army. However, in such a long time, he didn't even have a good exploration of the other party's strength.

If it's Shaw, you can give him a number!

Zheng Yuanyun sighed in his heart and knew that he was dissatisfied. It was good for Ma Chong to detect this degree. It was really difficult for him to find out the military deployment of Tianyuan city again.

As the saying goes, Ma Chong is not a professional scout, and he is bound to be deficient in some exploration methods. This is what Zheng Yuanyun prepared when he asked him to replace the chief scout. At the moment, he can't say more.

Moreover, the outer wall of Tianyuan city is really cunning.

Ouyang ordered the people to build the wall directly at the periphery of Tianyuan city. A wall higher than the original wall was built, and the two new and old walls were connected together, which formed a height gap.

The defenders in Tianyuan city can hide on the head of the old city wall. Looking up from their own side outside the city, they can't see this part of the defenders at all. Unless it's a war together, they will rise because of support when the war is fierce.

Therefore, at present, we can't make a general judgment according to the usual habit by visually measuring the number of defenders at the head of the city and taking into account a series of factors such as the other party's reserve forces, rotating soldiers and so on.

In this Tianyuan City, perhaps 100000 soldiers can be seen on the wall of the new city. According to past experience, it can be roughly inferred that the number of defenders is about 300000.

With this move of Tibetan soldiers, it's hard to say whether this 100000 is really 100000, or whether there are another 100000 hidden on the old city wall they can't see.

The difference between the two is twice the force, and the effect will be very different in battle, which makes Zheng Yuanyun dare not take it lightly anyway.

Another function is that there are only three gates in Tianyuan City, and the three walls have this heightening design, so Zheng Yuanyun can't see which wall has fewer defenders, which can become a breakthrough.

Although the soldiers on the side of the city wall he looked at at at this time were more empty than the previous main city gate, who can guarantee that once he took this city gate as a breakthrough, there will not be a large number of soldiers on the old city wall to snipe at them?

Unable to figure out the enemy's troop deployment, Zheng Yuanyun was unable to make a targeted siege plan.

After all, he has less troops than Ouyang. If he attacks the city, the troops he needs to invest are much better than the enemy. Without strength judgment, he can't attack the enemy's weaknesses, which makes his siege difficult.

In addition, the reason why Zheng Yuanyun wanted to find out the total number of troops in Tianyuan city was also on this important road of troop transportation.

The road is unobstructed. It seems that he doesn't have to fight Tianyuan city at all. He passes directly from one side. The other side can only stand in Tianyuan city and send them away.

But the question is, this is a trap for troop transportation. Can we go?

If he ignored Tianyuan city and chose to drive straight in, the other party could certainly let them in. Then, before he chased the city, Ouyang acted vigorously and led people from the back, and combined with the defenders in he chased the city to give Zheng Yuanyun a heavy blow.

Zheng Yuanyun couldn't make an accurate judgment if he didn't know the strength of Tianyuan city. Can he go this way?
