Chapter 452: Breaking the Barrier

"Trouble, it's actually raining...... Maybe it was because he learned that Xue Jingze attacked overnight and was ready to give him a gift, or because of his absolute trust in Xue Jingze, Tong Bingwen actually sent a message saying that he would delay his arrival for a few days. Tong Bingwen naturally has countless things in his hands, and Xue Jing's performance in terms of troop deployment and attack this time seems to be satisfactory to him, so there is no need for Tong Bingwen to run forward and grab credit with his confidant. After all, Tong Bingwen's current problem is that there is also no room for improvement. But Xue Jing was not satisfied with his performance, and Da Nanguan was still in Chunnan's hands.

Taking advantage of the fact that the reinforcements brought by Liang Xudao had not yet adapted to the severity of the attack at the head of the city, although they did not directly take the Great South Pass, the results were also extremely impressive. Liang Xudao brought the 10,000 reinforcements, and one-third of them were lost overnight, plus the losses of those sergeants in the original city, overnight, Da Nanguan began to be a little precarious. However, Da Nan Guan is still in Chunnan's hands after all.

It's been a total of four days, and Xue Jing's manpower and material resources smashed on the Danan Pass made Chunnan shudder. He almost never cared about the problem of consumption, all the siege equipment and fire oil bombs were distributed according to the need, and Tong Bingwen stayed in the back and personally took charge of the logistics and achieved excellent results, until now, Xue Jingze's various materials in his hands are still sufficient.

The walls of Da Nanguan have been cracked due to continuous burning, and although they are built with stones, they can't afford to toss like this. Sometimes, when a fire oil bomb smashes into the wall, the hot oil penetrates into the gaps between the stone bricks, where it burns out, and the degree of this burning will continue to deepen with repeated attacks. After the incessant attack, there were a few places on the city wall that were actually hot, and when the small raindrops fell on the city, there was actually water vapor in some places.

Xue Jingze's brows furrowed, he suddenly thought of something, and ordered loudly: "Ordinary ballistas fire with all their might, concentrate on the black place on the left city wall, and use fire oil bombs." Those big guys, give me a stone to bomb there. ”

Several officers under his command were stunned, but shrunk in a corner, and Chen Libo, the general who had been in charge of the maintenance of heavy equipment, his eyes lit up, he stood up and asked, "General, but you want to smash that wall?" ”

Xue Jing nodded and said, "I don't know if it's okay or not, if you can smash it open, naturally the whole line will go smoothly, even if it doesn't work, hehe, the ground rushes to the city gate or climbs the city to fight, you can have a cover." We just have the strength to advance in three ways, let's see how the other side copes. Chen Libo, you go in person. ”

Chen Libo rubbed his palms and said excitedly: "General Bulao ordered me to go in person, and when I want to be on time, I still have to come." ”

Xue Jing saw that Chen Libo was relaxed, nodded, and encouraged: "Go ahead, I'll ask for credit for you alone if you play well." ”

Whether in Xiling or Chunnan, a general like Chen Libo, who was promoted from a battalion officer in charge of equipment, does not seem to have a very high status. On the one hand, most of these people are not from generals, and no one supports them in the army, and in addition, everyone dislikes them for hiding behind and fighting artillery when they are fighting, especially when they are fighting with the wind, it is almost difficult to kill people. However, now the heavy weapons that are being driven by Dongping have become more and more an important part of the siege of the city, especially the attack and defense of the city pass, when the large corps array battle is carried out, the heavy equipment arms have dominated the battle to a certain extent. An officer like Chen Libo, who is outstanding in technology, has also obtained very good promotion opportunities because of this.

Chen Libo rushed to the ballista position, conveyed Xue Jingze's general order, and after deploying the ballista for concentrated bombardment and sectional support, he stood directly on the cannon body of the oversized ballista. He pulled out two brass rulers from his bosom, measured the angles, and carefully observed the current wind direction and other weather, and then he jumped off the ballista mount and tried the touch of the tendons in the torsion spring set...... After such a series of chattering movements, he whispered a series of orders to the gunners who were waiting for his orders.

Rows of fire bombs smashed directly on the city wall, which did not cause much reaction in the city, and after a few days, everyone's nerves were much stronger. The fine flames splashed by the fire oil bombs did not cause much damage to the city, but the Xiling army that climbed and attacked under the city was a little embarrassed. Along the city wall, the flames flowed through the gaps in the stone bricks of the city wall along the flowing fire oil, which was shocking.

However, when another batch of fire oil bombs also hit the height of the city wall, which is not embarrassing or embarrassing, Zhang Chen immediately realized that there was a problem!

He immediately summoned several officers in charge of firearms and heavy equipment and asked, "What does this mean?" But everyone looked at each other. But suddenly, there was a loud noise, accompanied by a whole piece of flying and shooting rubble in all directions. "General Zhang, come and have a look...... Walls...... The walls cracked. ”

The scorching flames, the uneven heat and cold of the masonry and the squeezing of each other, and the bombardment of the staggering weight of the stone projectiles wrapped in huge energy, finally opened a hole in the city wall. Zhang Chen bent down and leaned out of the city wall, glanced at the gap in the city wall, blood involuntarily poured towards his head, and all the sounds around him seemed to turn into a buzzing buzz, far away from him. Zhang Chen shook his head vigorously, and this feeling of dizziness began to understand himself. It's horrible. The gap in the city wall was quite small, and about three or four stone bricks were broken open and fell at the foot of the city wall. Although several Xiling soldiers were stoned to death, Zhang Chen would rather these stone bricks remain there. The moment he lost his mind, the two Xiling officers who were holding iron bows and supervising the battle under the city had already brushed two arrows and shot over. If it weren't for the guards around Zhang Chen to raise their shields to block it, Zhang Chen would almost have died on the spot.

After a few stone bricks fell, it was still very solid. The walls of the city wall are more than just a layer of stone bricks. The outermost layer is made of stone bricks, which are cut entirely from natural rock, and the inner layer is made of hard green bricks, densely packed together. Moreover, this layer of green bricks is the thickest layer in the city wall. Inside, there are huge stone beams. When the Great South Pass was built, these stone beams were the most difficult part, each stone beam was cut out of natural boulder, and then transported here, and then hoisted in place with an awkward method, cleaned up the burrs in the place where the stone beams were stacked and combined, made complex wedges and holes with them, polished and smoothed the rest of the surfaces that were in contact with each other, and then stacked the stone beams and combined them to be airtight. Then, the exterior wall was erected on the basis of the structure erected by stone beams. This complex and inefficient frame structure ensures that Da Nanguan stands tall. However, this kind of complicated matter, ordinary soldiers don't know, this gap in the city wall, there is still a long way to go before the hole can be formed to break through the city wall, and, if you think about it carefully, with the current rate of fire and accuracy of heavy equipment, you really don't know when you want to repeat this point until you can break through the city wall. However, the collapse of the city wall had a huge impact on morale.

Listening to the thunderous cheers of the Xiling army under the city wall, they attacked more and more vigorously, taking advantage of the low mood of the Chunnan soldiers at the head of the city, a team of Xiling elite soldiers rushed to the head of the city. Zhang Chen hurriedly took a pair of guards to plug the gap, while looking for Liang Xudao to report the situation, and then hurriedly asked someone to inform, so that the follow-up support forces could immediately go to the city to defend against the enemy. However, Zhang Chen fell into despair with a calamal sound, which was the sound of the thick wooden pillars below the gate breaking. In the past few days, the well-guarded siege vehicle has been damaged by four, but each time, Xue Jing did not hesitate to send another one. The soldiers of Xiling had to withstand the rain of arrows, stones, and hot grease on the city's head, move the broken siege engines, and push the new siege vehicles up to continue their work. Just in the city gate, Xiling lost 1,7800 people.

But, finally, the moment has come when all these sacrifices have been worthwhile. When the wooden strips that supported the two thick oak gates holding copper skin broke, the wood that had become loose after beating an unknown number of times could no longer withstand the attack. And the almost one-man high blanket that fixed the city gate on both sides was already covered with dark wounds. The Chunnan soldiers worked hard to support the wooden bars behind the city gate, but before this arduous work could play a role, the city gate could not withstand it first. With a bang, the gate fell towards the deep doorway, instead crushing many Chunnan soldiers underneath and turning them into powder.

"Assault of the whole army!" Xue Jing, who saw this scene in the telescope, shouted loudly, and this order was immediately shouted out by the officers layer by layer, and the entire Xiling army turned into a tide of attacks and rushed towards Da Nanguan. The soldiers, who seemed to have been drained of the last energy in their bodies just now, rejuvenated themselves and rushed towards the doorway; The reserves, which had been lined up not far from the city walls to replace their comrades who were attacking in front, ran and rushed forward; The soldiers who were resting in rotation got out of the camp tents one after another, picked up their weapons and rushed towards Da Nan Pass...... At this moment, Xiling's entire army was boiling.

The city wall was cracked, the city gate was blasted open, and the Chunnan soldiers at the head of the city of Danan Pass were terrified, and suddenly there was a tendency to collapse, and they were killed and fled by more and more Xiling soldiers who jumped on the city. And an hour and a half later, Xiling had captured the Chengguan part of the main body of the entire Great South Pass, and expelled the Chunnan army to the auxiliary buildings behind the Great South Pass to resist stubbornly......

After a few years, this famous pass has changed hands again.
