An exclamation from Zhu Lihua made those generals who suddenly sobered up from the separation of heaven and man and Xin Tong'er, who bowed their heads shyly, see at the same time that their own master general seemed to be crazy, leaning forward and wanting to walk down the city.

But where could he do it?

At this time, everyone who saw Lihua's abnormal expression immediately stepped forward, and asked with a solemn face, "Zuo Daren, what happened?" ”

"Yes, Zuo Daren, why are you so alarmed?"

After asking for a long time, they finally restrained the panic in their hearts, and then turned around and pointed out the outside of the city, and said to the generals with palpitations:

"They didn't plan to use those earthen platforms at all, and we dug tunnels under the cover of earthen platforms under Jilin City back then, and dug down the city walls, and now I'm afraid they are ready to do the same."

After saying that, Zhu Lihua glanced at Xin Tong'er again and said: "The earth platform is not hollow, and those soil are taken from the tunnel, if it is not for you this time, the yellow yin is in danger." ”

The stunned Xin Tong'er didn't react to the meaning of his words for a while after he finished speaking to himself, and actually stayed in the city, watching Lihua and the generals hurriedly walk down the city and go to the county hall to discuss countermeasures.

After a long time, when the herald of the herald came to the city to look for him, he realized how crucial his words played in the gains and losses of Huangyin City and the lives of the generals.

"Haha" laughed, Xin Tong'er, who was full of pride, quickly flew in the direction of the county hall without waiting for the guidance of the soldiers.

"Tell me quickly, if the Rong people want to dig a tunnel and want to trap the city wall, how should we deal with it?"

Seeing that Xin Tong'er who came in a hurry was sweating profusely, he hurriedly asked without waiting for him to stop and take a breath.

And Xin Tong'er just opened her mouth wide when she heard this, not knowing how to respond.

After a moment passed, he stumbled after thinking about it seriously: "Zuo Daren, it seems that the Rong army is not planning to dig the city wall. ”

"What?"

After Xin Tong'er finished speaking, some of the people who didn't understand the meaning of Xin Tong'er's words blurted out subconsciously, but Xin Tong'er thought that Li Li Hua didn't hear his words clearly and touched his head and said to Lu Lihua: "I mean, the Rong people don't seem to be planning to dig the city wall, but want to dig a tunnel through the city wall and enter our city." ”

"How did you come to this conclusion?" Zhu Lihua hurriedly continued to ask, but his face was obviously not as nervous as Fang Cai.

Xin Tong'er finally understood the reason why Lihua and the generals were worried, so he smiled and continued:

"Zuo Daren, from the amount of soil of the more than ten earthen platforms built by the Rong army, it can be seen that they are just digging tunnels, not trying to dig the city wall.

If they were to dig the city walls, they would probably be more than enough to build more than a dozen high platforms with just the excavated earth. ”

Xin Tong'er glanced at the generals a little proudly, but found that everyone had confused expressions, and Zhu Lihua also stared down at his feet and made no sound.

"The people on the left still have doubts, do they think they just haven't dug under the city wall yet?

Given the speed at which they were building the high platforms every day and the amount of earth they had brought in from outside the moat, the last general could guarantee with his life that they had already dug the tunnels through the walls of the city. I'm afraid that in another seven or eight days, the Rong army will appear in our city. ”

Xin Tong'er said as she slapped her chest with a crackling sound. But he saw that Zhu Lihua was still thinking about something, so he touched his head a little embarrassed.

It just so happened that at this moment, after looking up and seeing Xin Tong'er's appearance, she suddenly laughed.

"General Xin discovered today that the merit of the Rong army digging tunnels is comparable to the merit of General Wei leading the army into Lishan, General Wei haunted the mountains and fields to cut off the Rong army's grain road, and General Xin saved the building before the catastrophe of my Huangyin fell to the general, I will definitely remember this credit.

It's just that at this time, I still have something to understand in my heart, and I ask General Xin to solve my doubts. ”

Speaking of this, the smile on Lihua's face gradually receded, and it was replaced by a solemn expression, which made Xin Tong'er see it in his eyes and hurriedly said:

"Zuo, please speak, Xin must know everything, and he will say everything."

Zhu Lihua nodded and said: "When I sent troops to Ji Lin, I also built a high platform, and dug a tunnel under the high platform and finally stubbornly stayed on the Ji Lin city wall, although General Xin did not participate in that battle, but I must have heard of it, right?" ”

After Lihua finished asking, Xin Tong'er hurriedly replied: "The battle of Ji Lin captured by Zuo Daren is known to everyone in my Great Qin, and Xin Tong'er will be fascin......ated every time he thinks of this battle."

"Alright."

Xin Tong'er was about to continue, but Yu Lihua interrupted Xin Tong'er's chatter with a smile and continued: "You don't want to learn these useless things from them, it's better to focus on combat." ”

Xin Tong'er was shocked when he heard this, although he knew that Zhu Lihua was not angry because of his sycophants, but he still hurriedly bowed his head and responded respectfully. Then he listened to Lihua and asked:

"When I was outside Jilin City, there was no one in our army who was proficient in the art of construction like you, but I just wanted to dig the city wall as soon as possible, so I sent troops to dig tunnels day and night, and finally successfully dug a corner of the Jilin city wall.

In retrospect, it doesn't seem as complicated as you say it is. It's just that many of our soldiers were crushed into the earth and died before they could escape.

Therefore, I don't know why the Rong army outside the Huangyin City wants to dig down our city wall today, but why is it so troublesome? ”

Zhu Lihua asked Xin Tong'er seriously, and all the generals in the hall also looked at Xin Tong'er, as if they had the same doubts, waiting for Xin Tong'er to answer for everyone.

Xin Tong'er saw that everyone was looking at him, so he didn't dare to slack off and hurriedly said: "Zuo Daren, generals, although during the Battle of Jilin back then, the last general was just a small leader of the army who trained and cultivated every day in the rear, and he had never been to Jilin in his life, but from the mouths of others after the war, the last general still guessed the reason why the general was able to dig down a corner of the city wall.

The generals knew that the soil under the Huangyin City was full of stones and black soil, and that there was a lot of water in the soil under the ground, which was very close to the Yellow Water, so that the land here was much harder, and the buildings on the land could be supported more strongly.

Moreover, it is not easy to excavate when the weather is freezing cold, so if the Rong army wants to dig down the city wall, it must dig a large enough gap under the city wall to do so.

Although the general did not calculate how big a pit would have to be dug to do it, it was not an easy task to think about.

This was not the case with the city of Jilin, where there was a shortage of water and aridity, and the foundations under the walls were all made of sand, and the walls were mostly made of sand. Therefore, as long as a small pit is dug, the city wall will naturally break and collapse.

It's like walking on soft sand, and the seemingly flat ground will sink our feet into it. But if we walk on a path made of wet earth mixed with stones, we will not let the ground fall.

That's why the people on the left find it easy to dig into the walls of Jilin. ”

After Xin Tong'er finished speaking, everyone in the hall nodded their heads one after another, and An Moran and the others even gave Xin Tong'er a thumbs up and cast an admiring look.

However, after patting the armrest on the bamboo chair, Zhu Lihua said to the generals: "Pass the order, the wooden planks on the head of the city will continue to strengthen me, and we must not let the Rong army find out that we already know their plan."

Willow Jaw, you will lead 10,000 people to dig a deep ditch along the western city wall at once. I'd like to see how the rats react when they come out of the ground and see that we're throwing a banquet to welcome them. ”

After Lihua finished speaking with a smile, all the generals also laughed. Several of them walked up to Xin Tong'er's side and slapped and beat the general who was also smirking but couldn't hide the pride on his face.

Among the crowd, there are only a few people who are laughing unbridled with others at this moment, but they have complicated eyes to see that what cannot be hidden behind this chaotic laughter is the deep palpitations in the hearts of the generals.

.......

"General, listen, there's movement in the soil."

In the west city wall of Huangyin City, at the bottom of a huge trench about two zhang wide and about three zhang deep and completely parallel to the west city wall, several soldiers were holding a huge urn.

The tail of the urn was buried in the earth, and the mouth of the urn was tightly covered with a dark cowhide.

At this moment, Gao Yunce was lying on the cowhide, closing his eyes and listening carefully to the movement coming from the urn.

"Ding, knock, ding, knock."

After almost confirming that the dingdong sound in the urn was the sound of the pickaxe and shovel digging the tunnel hitting the soil, Gao Yunce straightened up with joy on his face, and nodded to the coffin on the trench.

He subconsciously turned his head to look at the countless tunnels in the trench that had been determined and marked, and involuntarily took a deep breath of cold air.

Today is the eighth day that Xin Tong'er found out that the Rong army was digging tunnels, and it is also the third day after the trenches in the city were completely dug, and it is also the first day that he can accurately detect the movement under the ground from those urns.

In other words, the Rong army really wants to dig tunnels to attack the city, and in less than half a day, I am afraid that these tunnels will be completely dug through, and a battle that has been quiet for more than ten days will also be restarted.

"This Lin Xu is so generous, there are only nineteen earthen platforms outside the city, but these tunnels are far more than nineteen. How many manpower it took to dig so many tunnels? ”

Lihua muttered a sigh to himself, but then he nodded to Gao Yunce, and after seeing Gao Yunce immediately wave his hand, countless soldiers who were ready next to the trench sent the bark of the withered grass tree to the places marked as tunnel entrances.

"It's been eight days, and they're finally going to dig through." Seeing that the soldiers were busy sending the dead branches of firewood to the trench according to the preset method, Zhu Lihua turned his head to look at Xin Tong'er, who was expressionless on the side, and said lightly.
