After the Kang army filled in the moat outside the northern city gate, the other Sogdian states also filled in the moat on three other sides for three consecutive days, but the Great Food Army still did not figure out the direction of the Tang army's main attack.

On July 12, the Tang army officially launched an attack on all four walls at the same time, and the Great Food Army had to deploy the same forces on all four walls at the same time.

However, the Tang army was the first to attack the city not to use infantry, but to use catapults on a large scale, only this section of the north city wall, the Tang army used fifty large catapults, and more than 5,000 stone bullets were dropped on the first day, at the beginning of the city wall on the big food defenders suffered a large number of casualties, but in the Tang army's stone bombs did not stop, the big food army only left the necessary observers, and the others all withdrew the city wall, and the city wall that had just been built not long ago was smashed by the stone bullets of the Tang army, and there was a section of the city wall that suffered extremely serious losses, There is a possibility of collapse with everyone, but this also makes the Great Food Army determine that the Tang Army's active direction is on the north city wall, but even so, the Great Food Army does not dare to be careless on the other three city walls, let alone transfer the defensive forces of the other three city walls to the north city wall to defend.

On July 13, this was the ninth day of the siege, and the Tang army officially used infantry to attack the city, of course, the main battle was the Kang army, the Shi army and the Cao army, a small number of troops bluffed under the three city walls in the east, west and south, and concentrated forces to attack the north gate, using siege ladders, wells, ballistas and other siege equipment.

Under the situation that the whole city is besieged and in a foreign country, the will to fight of the Great Food Defenders is not very strong, and although the combat effectiveness of the Kang Army, the Shi Army and the Cao Army is not strong, but for them, this battle is a battle to regain the lost territory, so everyone fights bravely, and the combat effectiveness is increased by two percent compared with usual.

The siege battle lasted for three whole days, and the losses of the Kang, Shi and Cao armies were relatively large, and the generals were also quite tired, so on the 14th of July, Zhao Ziliang withdrew them to rest and recuperate, and replaced them with the army of He, Shi, Mi and Bahanna to attack the city.

On this afternoon, when the siege of the city was in full swing by the army of He, Shi, Mi and Bahan, Zhao Ziliang observed the siege of the city and sent someone to find the lords of Cao and Kang.

Zhao Ziliang said to the generals and colonels under the command of Shuai Tai: "I look at this big food army up and down I am afraid that no one knows the siege tactics of digging earth and tunnels, I have seen it in the past two days, although it is close to the river, but the water level of the river is not very high, although the soil here is soft, but it is not completely sandy, it should be possible to dig underground, I intend to order the armies of all countries to attack head-on, and secretly send people to dig a tunnel from outside the city into the city, I don't know if any of you are willing to take this errand?" ”

Jia Chongjun stood up and hugged his fists and said, "General, the last general is willing to preside over the excavation of the tunnel!" ”

Zhao Ziliang looked at Jia Chongjun, pondered for a moment and asked, "Then do you know how to dig the tunnel?" ”

Jia Chongqian couldn't help but reach out and scratch his cheeks, thought about it and said: "It's nothing more than taking the soldiers to dig a tunnel first, and then digging into it along the tunnel opening, just like a mouse making a hole."

The generals couldn't help laughing, Zhao Ziliang looked at the others and asked, "Who else knows about this?" ”

Gao Shi stood up and arched his hand; "General, the lower officials once presided over the construction of the city wall, the excavation of the moat and the drainage canal in the city in Xilin. The excavation of the tunnel is different, because the excavation of the tunnel does not need to be wide and deep, so there are not many people who are always digging in front, at most five or six people, if it is the lower official who presides over the excavation of the tunnel, the lower official will divide the steps of the excavation into several parts: first, first divide the manpower into two parts, A is the excavation team, and it is divided into a number of teams, each team of six people, a team excavates a tea time and then quickly changes to another team, so as to ensure that the people digging in front of the man always have enough physical strength, The efficiency of excavation will also be the highest, team B is the soil handling team, they each have a basket, standing every other step, they are responsible for carrying the excavated soil, first use the basket to load the soil, and then pass out a basket, which can ensure that the soil is carried out as quickly as possible! Second, each section of the tunnel should be reinforced with wooden planks and wooden pillars to prevent collapse; Thirdly, the entrance to the tunnel should be covered with a large tent to prevent the defenders from seeing the clues, and the earth should be transported far away! ”

Zhao Ziliang laughed when he heard this: "Okay, at this time, Mr. Gao will be in charge of presiding!" ”

Gao Shi hurriedly arched his hand and said: "The subordinate takes orders!" ”

Zhao Ziliang said to Jia Chongjun, who was quite disappointed: "General Jia, although you are not proficient in this matter, General Ben still intends for you to assist Lord Gao, can you be willing?" ”

Jia Chongqian was overjoyed, this was a good opportunity to learn how to dig tunnels, where did he not want to, and hurriedly said: "The last general is willing!" ”

It didn't take long for the lord of Kang and the lord of Cao to arrive, and Zhao Ziliang instructed them to hand over the local people and military personnel they had recruited to Gao Shi and Jia Chongjun, saying that they had something to do, and the lords of the two countries did not dare not agree, so they immediately took Gao Shi and Jia Chongjun to lead the people.

Gao Shi and Jia Chongjun have manpower, immediately began to work, Gao Shi because of the relevant things, have a certain experience, know how to manage can maximize the efficiency of the work, under the organization of Gao Shi, the work of digging tunnels was soon launched, a basket of soil from a large tent was transported out of some lower positions.

After four days of excavation, Gao Shi finally organized people to dig the tunnel into the city fifty meters away from the city wall under a house, but they didn't know that the end of the tunnel was under a house, in order to prevent being discovered, after reporting to Zhao Ziliang, it was decided to dig the tunnel exit at night, and that night, an elite infantry of the Anxi Army had already been fully armed, and the rest of the Tang Army and other horses were also ready to go, and all the barracks were assembled, only waiting for the infantry in the tunnel to climb out of the tunnel and enter the city to kill at the city gate to open the city gate, the Tang army can rush into the city with elite horses.

Late at night, the lights in the Tang Army were bright, and Zhao Ziliang, Bian Lingcheng and other generals and officials in the army were impressively listed.

Everyone was waiting quietly, and Zhao Chongyu, who was responsible for leading the team into the city, walked in from outside the big tent with his sword at this time, and bent down to Zhao Ziliang with a fist; "General, our army is all ready, and it can break through the hole in the ground and enter the city at any time!"

Zhao Ziliang looked at Bai Xiaode, Li Sheng, Fugu Huaien, Xuan Er and others and asked, "How are the preparations for the army that rushed into the city from the city gate?" ”

Xuan Er stood up and hugged his fists and said: "General, all the camps have been assembled, just wait for the shouting and killing sound in the city gate, our army can rush out of the camp and kill at the city gate."

Zhao Ziliang nodded and asked Bian Lingcheng, "Is there anything else Lord Bian has to say to Anxi Jun?" ”

Bian Lingcheng said to Zhao Chongyu when he heard this: "General Zhao be careful and cautious, this opportunity is rare, and strive for success in one fell swoop!" ”

"Understood!"

Zhao Ziliang finally ordered: "Okay, then let's start!" Everybody, go and prepare."

"No!" The generals said yes and walked out of the tent one by one.

Zhao Chongxuan came to the big tent where the tunnel entrance was located, and there were infantry of the Anxi Army standing everywhere, all of which were going to enter the city from the tunnel to sneak attack, but the tunnel was not very wide and long, and it could not accommodate many people at the same time, so these people could only wait outside temporarily.

Walking into the tunnel, at this time, the tunnel was also covered with two columns of heavily armed soldiers, and there was only a small gap for Zhao Chongyu to pass through, but the soldiers saw Zhao Chongxuan coming over and gave him a passage for him to pass through.

Zhao Chongxuan said as he walked: "Brothers, this is our Anxi Army's opportunity to be ashamed, only through the tunnel into the city to open the city gate, let the city outside the city of our army brigade into the city, our army can break through this city in the shortest possible time with the minimum cost, and when it will go out of the tunnel, sooner or later it will be discovered by the Great Food Army, the fight is inevitable, I hope that the brothers will follow me closely, our first task is to open the city gate, as long as the city gate is opened, our task will be completed!" ”

Walking to the end of the passage, several local Kang Guo Zhuang Ding bowed to Zhao Chongyu, Zhao Chongyu pointed to them, let them dig through the tunnel mouth, several Kang Guo Zhuang Ding immediately understood what he meant, and immediately began to dig up with tools, the upward passage mouth has actually been dug to less than a foot from the ground, these Kang Guo Zhuang Ding dug to the ground in a few clicks, and a black hole appeared.

Jia Chongqian held a torch in one hand, climbed out of the hole along the ladder, and waited for the torch to illuminate the surroundings, and found that this was actually a room, and the room was poorly furnished and dusty, and it seemed that there had been no one living for a long time.

This situation made Jia Chongqian very happy, because the tunnel entrance was in this kind of closed room, and it was the least easy to be discovered by the big food army, and there was enough time for all the troops in the tunnel to come out.

As the Tang soldiers climbed out of the tunnel, the room was soon crowded with people, Zhao Chongxuan had already explored the house with a few soldiers, there was no one in the house, it was empty, he opened the door and took a few soldiers to reconnoiter in front of and behind the house, and found that it was not far from the city wall, only less than fifty meters, but he found that under the city wall, there were dense food army, servant army and local strong men.

The order was quickly conveyed, and the officers and men of the Tang Army crawled out of the tunnel to hide in the dark place in the house or under the eaves of the house, and more than an hour passed, and the Anxi army in the tunnel finally came out with more than 2,000 people.

At this time, Zhao Chongjun had confidence, he and his deputy general each led a team to divide labor, Zhao Chongxuan was responsible for leading a team to rush to the city gate to block the counterattack of the Great Food Army, and the deputy general led people to open the city gate and defend until the main army outside the city rushed into the city.

"Are you ready?"

The lieutenant nodded.

Zhao Chongxuan raised his horizontal knife and said in a deep voice: "Start, go!" ”

The Tang army divided into two groups and rushed towards the city gate, and the sound of heavy footsteps, the friction and collision of weapons and armor sounded······ (To be continued.) )
