After getting Pang Nuan's new order, this huge army immediately broke out with unprecedented execution, and before the sky was bright, the vanguard of the two wings had already arrived on both sides of Anyang City.

After arriving at the predetermined position, the two Zhao armies did not need to wait for Pang Nuan's further orders, and directly began to advance towards Anyang, aiming to complete the encirclement of the main force of the Qin army.

But when they arrived at the foot of Anyang City and the huge pocket was formed, Pang Nuan found that where was the shadow of the Qin army in the pocket?

These Qin troops, taking advantage of the night, had already retreated to Anyang City.

"Do they see that there may be a problem with our army's food and grass supply?"

"Hmph, see what, that's just a problem in the future, at least our army is okay now! Give me a siege! The siege begins early tomorrow morning! ”

"Sun Tzu's Art of War" has clouds, so the way to use soldiers, ten to surround it, five to attack it.

But now the troops in Pang Nuan's hands, let alone five times the Qin garrison, after a day of attrition, the number of troops he actually has in his hands now is only equal to Yang Duanhe's army defending the city, what can he use to compete with the Qin army?

Sure enough, in the next two days of siege battles, Pang Nuan was never able to make even the slightest breakthrough.

It wasn't until after the third day that Pang Nuan, who had realized that he could not take Anyang City, decided not to attack the city anymore, but to surround it but not fight, and just spent it on the front line.

"Then scold, scolding is enjoyable, and there are many rewards!"

On the sixth day of the siege, knocking on Erlang's leg, Yang Duanhe, who was sitting on the head of Anyang City, happily watched the two armies scolding each other in the air, and was happy.

"General Yang."

"You are?"

"In Xia Tangxuan, I came to assist the general in defending the city on the order of the Taifu."

"The boss is really, and he still doesn't worry about me. You see, at the moment, Zhao Jun has no other way than to scold and fight with my Great Qin soldiers, so what is there to help. ”

got up and led the tangled Xuan around the city, Yang Duanhe looked like he was winning, and even a little unhappy because of Tangxuan's arrival.

"General, what's going on there?"

Tang Xuan suddenly pointed to a small mound that he had selected and motioned for Yang Duanhe to take a look.

"There? It's nothing, the mound has always been there, it's not a big deal, what's the problem? ”

Yang Duanhe, who didn't find any problems, didn't know what this entanglement was at all, and he even took a closer look at the binoculars that Li Ling had issued to several generals before, and didn't find any problems at all.

"This thing is the telescope that Taifu said?"

"yes, you know that, too?"

"I've heard of it, can you lend it to Zaixia, so that Zaixia can take a closer look?"

"Ah, look."

After taking the telescope, he looked directly through the telescope and looked at the mound that he felt was problematic, which didn't matter, it was really a big problem.

"General! Not good, there is a problem! ”

"Questions?"

Grabbing back the binoculars, Yang Duanhe looked at the mound again, but he just didn't see any problems.

"Look, General, is there some grass on the mound that has died? And there are still scattered loess in some places? ”

"Oh, yes, what's wrong?"

"General! The general must immediately set up the ground to listen, in the next thought that Zhao Jun is very likely to use the block of the mound to dig the tunnel, and want to use the tunnel to break the city in one fell swoop! ”

"Impossible, if it's really digging tunnels, what about earthworks? The small mound didn't hide much earth, and digging from there to the bottom of the city, the earth had to be piled up as high as a city wall. ”

Yang Duanhe was noncommittal, it is not uncommon for such things to be used in siege warfare, but it should be impossible at the moment, because if you dig tunnels, it is impossible to do without earthwork, and Zhao Jun has no intention of building a fortress in front of the city.

The earthwork that can't be dug up has been eaten by Zhao Jun alone, right?

"No, general, please look, if the Zhao army is directly transported to the rear through the cover of many tents, of course the general will not be able to see the mountains of earth!"

Behind the mound is Zhao Jun's camp, tents are next to each other, hearing Tang Xuan say this, Yang Duanhe If he can't see it anymore, he will really be a fool.

"Someone! Come! ”

"The last general!"

"Hurry up, immediately follow Lord Xuan's instructions, set up a place in the city to listen, from today onwards, all matters related to the city's defense will be handed over to Lord Xuan before making a decision."

Yang Duanhe's biggest advantage is that he knows his mistakes and corrects them, and when he finds out that he is wrong, and there are masters around him, he will never care about his so-called face problems, so he will hold Tang Xuan to the supreme position on the spot, and hand over the Anyang city defense directly to Tang Xuan.

Under the guidance of Xuan Xuan, the Qin army stationed in Anyang City immediately began to act, digging several deep wells along the inner edge of the city wall in just two days, and then set up a thin cylinder in the well, the mouth of the cylinder was covered with cowhide, and sent people with intelligent hearing to listen at all times in the well.

Not long after the setting was completed, the situation was discovered in several places below the corner of the southwest city wall.

"Damn, they are really like mice, hitting the hole in the ground under Lao Tzu's nose!"

Through several adjacent places, Tang Xuan quickly determined the approximate location of the enemy's tunnel, and judged that in two days at most, this tunnel would probably pass through the city wall and dig into the city.

Yang Duanhe looked afraid.

"General, please also immediately order someone to refill all the deep wells near here and compact them to only two meters above the ground."

"Why is that?"

With the help of listening to the ground, he can quickly determine the location of Zhao Jun's tunnel, so that he can react as soon as possible, such a good thing was originally proposed by Xuan Xuan, why is it that he is about to dig into the city now, but Xuan Xuan wants him to fill it in?

"There is no moat in Anyang, and the depth of the enemy's tunnel is still unknown, if the tunnel is dug directly into the deep well, wouldn't it be equivalent to helping Zhao Jun?"

"No, it's just a well, and even if no one is there, they won't be able to run out much."

"It's better for the general to be careful."

"Okay, okay, then do as you say."

Yang Duanhe no longer argued, and directly began to order people to do what he was told.

However, there are far more ways to entangle Xuan, and he has the next step to deal with it.

While filling in a few places near the foot of the city wall, Xuan Xuan began to carefully observe the terrain around the city wall, and then kept measuring the distance with his feet back and forth, as if he was going to make some alternative arrangements.
