Chapter 613 I Have Even Dug up the Graves of the Former Kings of the Qin Dynasty, so Why Can’t I Dig Through Your Helu City?

Outside Helu City.

The 2500-year-old coward suddenly raised his right hand and shouted in a low voice:

"dig!"

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

The thousand soldiers beside Naodan quickly put down their hammers and dug the soil in front of them with copper shovels.

Half a quarter of an hour later, Naodan gave the order:

"Smash!"

Half of the soldiers hurriedly threw away the copper shovels, picked up wooden boards and placed them on top of the tunnel. Half of the soldiers pierced the thick wood into the ground on both sides of the tunnel and pounded it with heavy hammers!

At the same time, flying rocks weighing more than a hundred kilograms hit the city wall above the ground, making a deafening roar.

The Tingdi Urn buried in Helu City trembled visibly with the naked eye. The Tingdi soldiers of the Chu army covered their ears in pain and staggered back.

After forty boulders were smashed one after another, the Qin and Qi coalition forces had already built a tunnel support structure using planks and giant trees.

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

The support structure was built with the help of the cover of flying rocks. During the filling of the flying rocks, the tunnel space was expanded with a shovel. The whole set of movements was smooth and skillful, just like Da Qin's production line.

Not far away from Naodan's headquarters, there were thirty soldiers and horses doing the same actions as Naodan's troops!

The tunnel entrance.

Su Jiao quickly stretched out his right hand to protect the top of Ying Chengyu's head: "Coach, be careful!"

"The underground is narrow and the coach does not need to enter."

"Leave the matter of hole attack to my department."

The cave attack tunnel is usually dug to be at least wide enough for two people to advance side by side for the purpose of quickly transporting troops, but it will never be enlarged for the comfort of a few soldiers.

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

This height is enough for the grassroots cave attackers to move around and work normally, but for fierce generals like Ying Chengyu, they have to bend down hard to pass. If they are not careful, they will bump into the top of the tunnel.

How could Su Jiao be willing to let Ying Chengxuan suffer this injustice?

However, Ying Chengyu patted Su Jiao's hand and motioned for Su Jiao to take his hand away.

After ducking into the tunnel with a low body, Ying Chengyu said in a warm voice: "If I don't go into this tunnel for a while, how can I personally feel how much grievances you have suffered because of my orders?"

Ying Chengyu is indeed tall and strong, aren't Su Jiao and other generals tall and strong?

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

Su Jiao said cheerfully: "What a grievance this is."

"At the end of the past year, we dug from the east of Yongcheng to the west of Yongcheng, almost digging through the entire Yongcheng, and finally hid under the Daqin Festival for a long time."

"At that time, the general did not have so many robes under his command, only hundreds of brothers."

"There is no cover from flying rocks, so you have to be careful in everything you do."

"Didn't you come here just like that?"

"This point attack is just mediocre for us!"

Su Jiao, Naodan, Zhang Xiao and other main generals of the cave attack force were all veterans who had participated in the Battle of Yongcheng.

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

In terms of difficulty, this battle cannot be compared with the Battle of Yongcheng!

Ying Chengyu couldn't help but reveal some memories in his eyes: "I will remember that you had just assumed the position of Lord of Five Hundred at that time."

"Although he already has a brave appearance, his complexion is fair and his body is much thinner than now. It seems that he has not endured any hardship. He is a handsome young man who is rare in the world."

Su Jiao also smiled and said: "At that time, the king was not as tall as he is now, nor was he as strong as he is now, nor did he have the evil aura that he has now. At first glance, he looked like a refined gentleman."

"When I heard that your Majesty asked me to dig through the royal tomb, the robes couldn't believe that this was an order that Your Majesty could give."

The two tough warriors were bent together, walking awkwardly and hard in the low tunnel.

But neither of them felt uncomfortable. On the contrary, they recalled the days when they were in Yongcheng underground and slept under the tomb of the former king of Qin.

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

"Coach?" Naodan looked back in astonishment and exclaimed in surprise.

Then Ruodan hurriedly ran up to Ying Chengyu with his body low and his legs upturned, and bowed his hands in a salute: "Last general, Coudan, pay your respects to the coach!"

Ying Chengyu waved his hand: "No need to be polite."

"My soldiers went out to hunt some game today, and I ordered the chef to make meat porridge to reward you all."

Looking at the soldiers behind Ying Chengyu who were carrying wooden barrels, Naodan gratefully handed over his hands and saluted: "General, I would like to express my gratitude to the commander on behalf of our troops!"

After greeting the soldiers to distribute the meat porridge, Ying Chengyu asked in a low voice: "Is the excavation going well?"

"Do you need anything? You can tell me!"

Naodan immediately said: "Coach, please don't worry."

"When our army filled the trenches last time, it was easy for our troops to dig, but it was difficult to build wooden frames to support the tunnels."

"It's not until today that our troops throw rocks into the battlefield, and our troops can throw off their arms and pound wood."

"If our army can increase the number of flying rocks, our troops will dig faster."

Ying Chengyu said without hesitation: "Starting from tomorrow, the number of flying rocks our army throws every day will increase by 30%."

"All the flying stones our army has accumulated 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 slightly dissatisfiedly: "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 report."

"The general can be sure 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 and 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 close to the urn and listened, and 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 five hundred stones of tung oil and a hundred stones of wolf dung here, ready for use at any time."

"Dig a shallow trench 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!"
