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 your Helu City?

Outside Helu City.

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

"dig!"

Naodan'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 stuck them to the 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 down one after another, the Qin and Qi coalition forces had already built a tunnel support structure using wooden planks and giant trees.

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

"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."

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

"Didn't you come here too?"

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

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

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

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

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

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."

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."

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.

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

"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."

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

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

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 injustice you have suffered because of my orders?"

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

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

"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."

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

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

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 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.

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 soldiers!"

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

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

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

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

"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."

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

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

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

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

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

The support structure was built with the help of the 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.

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

"This acupuncture attack is just mediocre for us!"

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 tunnel entrance.

"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 thrown by our army 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 unit will definitely achieve success!"

Ying Chengyu 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 subordinates for a while, 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, Nao Dan carefully dug the earth on the side. But just as the ingot in his hand was thrust out, another copper ingot 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, Naodan, 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!"

"Pass this 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, his hands constantly rubbing 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 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."

"It is very likely that the Qin-Qi coalition army 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.

The method of cracking the acupoint attack strategy is even more clearly introduced in the book "Mozi"!

Zhaocen smiled lightly and ordered: "Assemble seven thousand guards here to guard 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!"
