Because the first-line outer line was occupied by his own side, the Qin army in the first-line sky was no longer patient, so after the soldiers of the Qin army appeared at the entrance of the first-line skyline, they still controlled the Qin army on both sides of the first-line skyline, and began to try to open up the connection with the first-line sky.

You must know that what follows is the war of attrition between the two sides, as the fourth regiment of the Qin army, although because of the advance preparation, each soldier has enough bullets of ten bases, but after all, the Yuan army still has nearly 20,000, plus there are still 50,000 or 60,000 government troops, the fourth regiment of the Qin army has to prepare in advance.

Originally, according to Du Xinping's meaning, that is, to dig a trench from their defense line, which could not only connect the second regiment, but also guard against Yuan's army, but after he pulled out the soldiers and started the operation, he found that it was almost impossible in this way, because it is no wonder that the first-line heavenly city wall was built four or five hundred meters away from the first-line entrance, because the more you go forward, the more rocks there are, and it is impossible to dig at all.

In this way, the plan to stubbornly come up with a trench to connect the two sides will be in vain, but Yu Zhengdao knows that they can't do nothing at this time, after all, the Yuan army still has reserve forces, if the other party comes from the city that never sleeps, and then cooperates with the Yuan army that has now entered the first line of the sky, not to mention that the Qin army will be easily defeated, but it will definitely make the Qin army embarrassed, so in order to avoid such a passive situation, the Qin army not only needs to control the position in the first line of the sky, but also needs to drive the Yuan army out of the first line of the heavenly city.

"How?"

Qin Huo was a little anxious after receiving that he could not use trenches to connect the fourth and second regiments of the Qin army together, after all, if he used his life to attack the position of the Yuan army, although they had three directions to attack, the number of the Yuan army was obviously much larger than them, so in exchange, in the end, he could only make his side lose its combat effectiveness.

"Then use artillery bombardment, Du Xinping's four regiments cooperate on both sides, and the first and third regiments simultaneously contain the attention of Yuan Jun and the various warlords in Guangchuan!"

With Xiao Fei's order, the rumbling artillery was advanced from the first line of heaven and the mouth of the first line, and even more than that, on the positions defended by the first and third regiments of the Qin army, one artillery was also pushed out of the trenches, which directly shocked the Guangchuan warlords who were driven by the Yuan army to surround them.

In the face of such a muzzle, Yuan Wushuang's face was ugly, because according to the coverage of artillery, the area defended by their Yuan army on the first line of the sky was covered by the opponent's artillery, and because they were sandwiched in the center by the Qin army, their strategic position was extremely narrow, if they insisted on defending there, then they would become a live target.

But if he gave up, although Yuan Wushuang was mentally retarded in battle, he was not stupid, knowing that if he gave up the No. 2 position he had seized from the Qin army, then the support from the city that never sleeps would fall into the same situation that the Yuan army he led before could not enter Guangchuan and could only fight hard, and maybe he would be defeated by Yu Zhengdao again, after all, the Yuan family's support was also limited.

"No, absolutely not, give me to hold the No. 2 position at all costs, and ensure that our reinforcements can enter Guangchuan immediately after defeating the Qin army on the outer line!"

The No. 2 position on the first line of the sky line occupied by the Yuan army is a defense line 100 meters long and 50 meters deep, to be honest, such a defense line is narrow whether it is deep or frontal defense, but originally this is in cooperation with the No. 1 and No. 3 positions on both sides, so at that time such a defense line was enough for the Qin army, after all, the personnel who rushed out from the first line of the sky were only about ten meters of road, and they could not set up a formation, but obviously now such a position fell into the hands of Yuan Jun, facing the Qin army on both sides, as well as the Qin army attacking from the outside, it was definitely not so easy to defend, so Yuan Jun made great efforts to dig up to 300 meters on the flanks of the Qin army on both sides, a defense line more than 100 meters deep, so that the entire defense line of the Yuan army presents a T-shape, wrapping the two positions of the Qin army, and can attack these positions of the Qin army from both sides, completely changing the strategic environment of the Yuan army.

The Second Regiment of the Qin Army, although it was inconvenient to consign because of the narrow nature of the first line, because the Qin Army was stationed on the two lines inside, the Qin Army could calmly pull out one artillery piece after another, and finally put out more than 50 artillery positions.

During this period, the Yuan army of course saw the crisis of the situation, and even Yuan Shoucheng, who was in charge of defense, sent Yuan Jun's soldiers to blow up these artillery, but because he would face three fronts of fire when he rushed over, Yuan Shoucheng gave up after two attempts.

On the camp defended by the first and third regiments of the Qin army, the commander of the first regiment, Qin Wuxing, and the commander of the third regiment, Dai Dou, seemed to turn a blind eye to the encirclement of the various warlords in the surrounding Guangchuan, but instead commanded the artillery to also point the guns at the position of the Yuan army.

"Can't give them a chance to fire, give me a chance to rush forward!"

Li Renyi led a regiment of the Yuan army under his control, and with the 2,000 people under Wang Chan's control, he became the one who drove the Guangchuan coalition army, especially in the face of the Qin army's seemingly unscrupulous preparation of artillery bombardment of the Yuan army's camp, Li Renyi knew that if he couldn't stop this, then he might be punished by the enraged Yuan Wushuang.

However, Li Renyi was very smart, he knew that if he let all the Guangchuan warlords attack together, then with the resentment of being forced by him before, maybe they would turn back and attack him, so he left Zhang Zhuo and the others by his side, and then let Zhang Zhuo and other five marshals' subordinates drive the small warlords of Guangchuan to attack.

At this time, the soldiers of Li Renyi and Wang Chan drove the soldiers of the four marshals, and the soldiers of the four marshals drove the soldiers of the small warlords of Guangchuan, so because the soldiers of the four marshals were not the first to die, they also acquiesced in this behavior.

And the little warlords want to resist, not to mention the strength of the Yuan army, the strength of the five marshals who are willing to be eagle dogs is not something they can deal with, so although they scolded the five marshals in their hearts, they can only obediently lead the soldiers to attack the positions of the first and third regiments of the Qin army under their drive.

For the Guangchuan soldiers who rushed in, Qin Wuxing and Dai Dou didn't pay attention, they just looked at the direction of the sky and waited for the sound of artillery firing to come from, and they didn't even let the artillery test the landing point, because all the artillery of the Qin army had already tested the landing point before the Yuan army came in, which was also the reason why Dai Dou knew that Yuan Jun was not the opponent of the Qin army, because they had a Yu Zhengdao.

"Kill!"

The soldiers of the coalition army looked hideous after approaching the Qin army's position, as if they could frighten the Qin army inside and then break through the opponent's position, but they didn't know that the Qin army hiding behind the trench was just smiling contemptuously.

"A bunch of people are here to die!"

A Qin soldier named Li Gang, who was lying in the trench, checked his rifle again, and even pulled out the bolt to make sure that the bullet inside was loaded, and then pointed his gun at the allied soldiers who were roaring and rushing.

Even Li Gang closed his eyes, because he had to follow the order to shoot as soon as possible, and closing his eyes could make his reaction more sensitive.
