My brother Ying Zheng, who dares to kill me?

Chapter 613: I have even dug the graves of the late kings of Great Qin, but can I still dig through

Outside Helu City.

The 250-man leader, Naodan, suddenly raised his right hand and shouted in a low voice:

"Dig!"

Naodan's voice was not loud, but it was particularly abrupt in the narrow tunnel.

The thousand soldiers beside Naodan hurriedly put down their hammers and dug the soil in front with copper hoes.

Half a quarter of an hour later, Naodan just ordered:

"Smash!"

Half of the soldiers hurriedly threw away the copper hoes, picked up the wooden boards and attached them to the top of the tunnel, and half of the soldiers stabbed the thick wood into the ground on both sides of the tunnel, and pounded it hard with the heavy hammers in their hands!

At the same time, above the ground, more than a hundred pounds of flying stones hit the city wall, making a deafening roar.

The listening urn buried in Helu City trembled visibly, and the Chu army's listening soldiers covered their ears in pain and staggered back.

After forty huge stones fell one after another, the Qin-Qi coalition had already built a tunnel support structure with wooden boards and huge trees.

Naodan held a roll of silk cloth in his hand, looked at the topographic map drawn on it, and ordered again without raising his head: "Dig straight ahead!"

With the help of flying stones to build the support structure, the space of the tunnel was expanded with a hoe during the filling of flying stones. The whole set of actions was smooth and skillful, just like the production line of the Qin Dynasty.

Not far from Naodan's troops, there were thirty troops doing the same actions as Naodan's troops!

At the entrance of the tunnel.

Su Jiao quickly stretched out his right hand to protect Ying Chengjiao's head: "Master, be careful!"

"The underground is narrow, the master does not need to enter."

"Leave the cave attack to our troops."

The cave attack tunnel is usually dug to a width that is at least enough for two people to move side by side in order to quickly transport troops, but it will never increase the height for the comfort of a few soldiers.

The average height of the Qin-Qi coalition is about 1.7 meters, and the cave attack troops will deliberately select relatively short soldiers, so the height of the tunnel is only 1.7 meters.

This height is enough for the basic-level soldiers to walk and work normally, but for a fierce general like Ying Chengjiao, he must bend down hard to pass through, and if he is not careful, he will hit the top of the tunnel.

How could Su Jiao bear to let Ying Chengjiao suffer this injustice?

Ying Chengjiao patted Su Jiao's hand, signaling Su Jiao to take his hand away.

Diving into the tunnel with his body bent, Ying Chengjiao said softly: "If I don't walk in this tunnel, how can I feel how much injustice you comrades have suffered for fulfilling my orders?"

Ying Chengjiao is indeed tall and strong, but are Su Jiao and other generals not tall and strong?

Just because of Ying Chengjiao's order, these generals squatted in the tunnel for almost a month!

Su Jiao said cheerfully: "What kind of grievance is this?"

"In the past, I dug from the east to the west of Yongcheng, almost digging through the entire Yongcheng, and finally hid for a long time under the Qin Jichou."

"At that time, I didn't have so many comrades under my command, only a few hundred brothers."

"There was no flying stone to cover, and we had to be careful in everything we did."

"Didn't we get through it that way!"

"This cave attack is nothing to us!"

Su Jiao, Naodan, Zhang Xiao and other main generals of the cave attack troops in this battle are all veterans who participated in the Battle of Yongcheng.

For these veterans who had dug through Yongcheng, this cave attack was just a little larger in scale than the Battle of Yongcheng.

In terms of difficulty, this battle is not comparable to the Battle of Yongcheng!

Ying Chengjiao couldn't help but reveal some memories in his eyes: "I remember that you had just taken office as the Lord of Five Hundred."

"Although you have a brave and brave appearance, your skin is white and your body is much thinner than now. You can see that you have never suffered any hardship. You are a rare handsome young man in the surrounding area."

Su Jiao also laughed: "At that time, the king was not as tall as he is now, nor as strong as he is now, and he didn't have the fierce aura he has now. He was a gentleman at first glance."

"When I heard that the king wanted us to dig through the royal tomb, my comrades didn't dare to believe that this was an order that the king could give."

The two strong and muscular generals bent over together and walked awkwardly and hard in the low tunnel.

But neither of them felt uncomfortable. Instead, they recalled the days when they turned the rivers and seas underground in Yongcheng and slept under the tombs of the former kings of the Qin Dynasty.

After walking for a long time, Ying Chengjiao finally saw a flashing figure.

"Commander?" The coward looked back in surprise and exclaimed in surprise.

Then, Naodan hurriedly crouched down and ran to Ying Chengqiu, bowing his hands and saluting: "I am Naodan, meeting the commander!"

Ying Chengqiu waved his hands: "No need to be polite."

"My family soldiers went out to hunt some game today, and I asked the chef to make it into meat porridge to reward all my comrades."

Looking at the family soldiers carrying wooden barrels behind Ying Chengqiu, Naodan bowed his hands again with gratitude: "I thank the commander on behalf of my soldiers!"

After asking the family soldiers to distribute the meat porridge, Ying Chengqiu asked in a low voice: "Is the excavation going smoothly?"

"Anything you need? You can Speak!"

The coward immediately said: "Please rest assured, commander."

"When our army was filling the trenches last time, our troops were able to dig easily, but it was difficult to build wooden frames to support the tunnels."

"Until today, our army threw flying stones into the battlefield, and we were able to throw our arms and pound the wood."

"If our army can increase the number of flying stones, our excavation speed will certainly be faster."

Ying Chengjiao said without hesitation: "Starting tomorrow, the number of flying stones thrown by our army every day will increase by 30%. "

"All the flying stones accumulated by our army so far and polished every day will be thrown away within half a month."

"In addition, I will also ask Paoze to continue digging and filling trenches to provide cover for your troops."

Naodan smiled relaxedly and said, "That's enough!"

"Within six days, our troops will definitely be able to dig under the city wall of Helu City."

"Within ten days, our team will definitely achieve success!"

Ying Chengxuan made a serious promise: "When this battle is won, all those who attack the acupoints will be heavily rewarded!"

"If you take care of yourself and work bravely, I will definitely live up to you!"

Naodan shouted excitedly: "Wei!"

After Ying Chengxiao encouraged his troops again, he hurriedly left and headed towards another hole attack force.

But the oily meat porridge in his belly turned into strong energy, motivating all the soldiers under Naodan's command.

Wipe off the porridge stains from the corner of your mouth, and the coward will appear again:

"dig!"

——

August 28th.

Naodan ordered most of the soldiers to return to the ground first, and he only led ten of his followers to stay underground.

Holding a copper shovel in his hand, Naodan carefully dug the earth on the side.

But just as the hammer in his hand was thrust out, another copper hammer poked out from the earth!

Naodan looked happy and quickly stabbed him several times in succession.

The two copper shovels worked together to dig a hole in the side of the earth. Naodan and Zhang Xiao looked at each other across the hole!

Resisting the urge to cheer, Naodan stretched his hand out of the hole and held hands with Zhang Xiao who was equally excited and impatient across from him.

The soldiers beside the two men also quickly picked up the copper shovel and continued to open up along the entrance of the cave.

Accompanied by the rustling sound of falling earth, the entrance of the cave expanded into a passage more than twenty feet wide!

On both sides of the space where Naodan and Zhang Xiao were, soil was being dug out.

Finally, thirty cave attack troops met ten feet underground.

An underground space one hundred feet long and twenty-eight feet wide.

This is it!

After Zhang Xiao looked around the audience, he patted the basket on his back.

Nao Dan understood immediately.

After ordering his soldiers to carry the freshly excavated soil on their backs, Nao Dan took out a bamboo tube from the back of his backpack, and while moving towards the entrance of the cave, he spilled the oil inside the tube.

It wasn't until he ran back to the ground and got out of the tunnel that Naodan took a deep breath of fresh air, cheered up and said, "Repay!"

"The last general, Nao Dan, has given all his orders, and all our troops have withdrawn."

"The various units of our army have successfully converged, without missing a beat!"

"Live up to the coach's trust!"

Following Naodan, Zhang Xiao and other acupoint attacking troops emerged from the ground one after another.

After counting the number of people, Ying Chengyu nodded vigorously with a smile on his face: "Good!"

"Very good!"

"Send the general's order!"

"The whole army is out of camp, ready for the decisive battle!"

"All catapults are mobilized to the northwest of Helu City, targeting the northwest outer city wall of Helu City."

"Smash me to death!"

All the generals raised their hands in unison: "Wei!"

Ying Chengyu looked at Su Jiao again: "Captain Su Jiao!"

"ignition!!!"

——

Half an hour ago.

Helv City.

"Captain Peng?" Zhaocen, who was awakened from his sleep, had just walked out of the city gate building when he saw Peng Qing pacing back and forth anxiously outside the city gate building, rubbing his hands against each other.

Zhaocen asked with slight dissatisfaction: "Does Chief Peng have something important?"

Peng Qing quickly bowed his hands and said, "Your Majesty!"

"I asked to see you late at night because I have something important to tell you."

"The general can confirm that the enemy is definitely conducting a hole attack!"

Zhaocen frowned slightly: "Really?"

In Zhaocen's view, the possibility of Ying Chengyu launching an acupoint attack was extremely slim.

Peng Qing's false alarm in the previous episode made Zhaocen even more distrustful of Peng Qing.

However, this time, Peng Qing said firmly: "It's true!"

"Tonight, the Qin-Qi coalition forces were not covered by flying stones, and they did not order soldiers to attack the city. It was quite quiet on the battlefield."

"Under this environment, the sound of the Qin-Qi coalition digging the ground cannot be hidden from us!"

"The general can guarantee that the Qin-Qi coalition is definitely digging underground!"

Zhaocen's eyes narrowed.

Although Zhaocen still didn't believe that Ying Chengyu would choose the acupoint attack strategy.

But what if?

Zhaocen asked in a deep voice:

"Perhaps Commander Peng can tell where the Qin-Qi coalition forces intend to attack?"

Peng Qing hurriedly said: "You can hear it."

"The Qin-Qi coalition forces are digging in the northwest of our city."

"Listening to the sound of the Qin-Qi coalition digging, they should have reached the wall of Helu City!"

Zhaocen immediately ordered: "Go and report to the king quickly, and tell him that the Qin-Qi coalition really wants to attack the cave."

"Captain Peng, please quickly take me to the place where the Qin and Qi coalition forces attacked!"

Under the leadership of Peng Qing, Zhaocen rode his horse to the foot of the city wall in the northwest city.

Peng Qing pointed to a section of the city wall and said, "Please take a look, your Majesty. There are sounds of the Qin and Qi coalition digging the ground all over this area."

"The Qin-Qi coalition probably dug not just one tunnel, but a large number of tunnels!"

Zhaocen immediately stepped forward, leaned closer to the earthen urn, and listened attentively. Sure enough, he heard the rustling of footsteps and the sound of digging!

Zhaocen's heart suddenly trembled, but then he chuckled softly: "Instead of using a surprise attack through the tunnel, do you intend to use the tunnel to directly influx a large number of troops into our Helu City?"

"This is indeed something Qin Chang'an can do."

"Of course, Lord Qin Chang'an doesn't read military books?"

Why didn't Zhaocen think that Ying Chengyu would launch an acupoint attack?

Because apart from being weird, the hole attack strategy has almost all shortcomings.

As for the method of cracking the acupoint attack strategy, the book "Mozi" introduces it clearly!

Zhaocen smiled lightly and ordered: "Assemble seven thousand guards here to guard the place strictly."

"Add another 500 shi of tung oil and 100 shi of wolf dung here, ready for use at any time."

"Dig a shallow ditch to divert the water from the Inner East City moat to this place."

"Send the order to the entire army and prepare to take advantage of the situation to counterattack!"
