With the cheers and cheers of the soldiers under the city, Li Yuan immediately opened a killing spree after successfully ascending the city tower, and where the brilliance of his unique Wuji True Yuan sword flashed, a large number of defenders of the special attack division fell to the ground one after another.

Taking advantage of Li Yuan's attraction to a large number of defenders, many Tongtian Sect masters behind Li Yuan took the opportunity to follow closely, and soon climbed the tower to start a bloody battle with the soldiers defending the city.

Li Yuan was extremely angry in his heart because he was frustrated by the special attack division yesterday and the situation was passive, and he understood that if he could not prove in front of the soldiers of the battalion as soon as possible that the special attack division in Shiziling was not so powerful, then it would be extremely detrimental to the morale of his own army.

So early this morning, Li Yuan took his closest 30,000 guards to the Black Dragon City to call for battle, and asked Shi Ziling to lead the team to fight. Unexpectedly, no matter how his subordinates scolded under the city, there was no reaction from the Black Dragon City, and Shi Ziling not only did not lead the special attack division out to fight, but also did not even show his face.

Li Yuan also thought that Shi Ziling was trying to delay time and wait for reinforcements, and he knew that if Shi Ziling and Nangong Xia's brigade arrived one after another, it would definitely cause great pressure on himself who was suffering from the enemy on his back. But whether to advance or retreat is a dilemma, and it seems that no matter where you go, it is not ideal.

After repeated weighing, Li Yuan still thought that the Black Dragon City had relatively few troops, although Shi Ziling was in charge himself, but with his absolute superiority in troops, it was entirely possible for him to break through the Black Dragon City before the reinforcements from Nangong Xia and the Songhu Army arrived. After making up his mind, Li Yuan immediately ordered his men to attack the city with all their might.

However, the ensuing siege was not ideal. The defenders of Black Dragon City have greatly increased their strength after being replaced by the special attack division of Shiziling, and they have unique features in the use of various fortifications, whether it is arrows, rolling wood or flying stones, the special attack division has a unique combination mode to use, and the offensive and defensive efficiency is much higher than that of the original defenders of the Xiahou family, which has caused great damage to the siege troops of Li Yuan's army.

After Li Yuan was forced to sneak into the martial arts masters above the incense master level in his Tongtian Sect, although many people did climb the city tower, they still had little success.

The individual combat ability of the special attack division was far stronger than that of the defenders of the Xiahou family, and it also practiced a special defensive formation, from a small combination of three or five sergeants to a team defense of dozens of people, and it was very skillful in using it. Even in the face of Tongtian Sect masters whose personal strength was much higher than their own, once the sergeants of the Special Attack Division used the Optimus Prime defensive formation taught by Shi Ziling, they would not fall behind at all.

In the face of the stable and efficient defense of the special attack division, the siege team sent forward by Li Yuan suffered heavy losses, while the special attack division fought in a condescending team, but there were few casualties.

After a whole day, the progress of the siege did not make the slightest progress, but the wounded soldiers who were knocked down under the city spoke of the ability of the special attack division, which further frustrated the morale of Li Yuan's army. Many people privately think that Shiziling's special attack division is too powerful, and with them guarding Black Dragon City, it is impossible for Li Yuan's army to succeed.

Li Yuan was anxious in his eyes, he knew that it was no longer a question of when he would be able to capture Black Dragon City, but that the morale of his own army continued to be low under the continuous suppression of the special attack division. If this momentum is allowed to continue, once Shi Ziling's follow-up men and horses arrive with Nangong Xia's reinforcements, the special attack division will turn from defense to offense, and the morale of his own army will only be even more sluggish.

In the evening, Li Yuan ordered all the military horses in the entire camp to drive to the front of the city to attack the city in turn, expecting that Shiziling's special attack division had limited troops after all, and he would definitely be able to drag the opponent down by using wheel tactics.

However, as time went on, more and more siege soldiers fell under the city, but the special attack division on the tower did not show fatigue.

At this time, Li Zhun, who had not recovered from his injuries, said something that attracted Li Yuan's attention.

Li Zhun said: "Our Tongtian Sect has already had a lot of helm masters and incense masters killed in today's siege battle, according to several seriously injured incense masters, the team defense ability of the special attack division is extremely strong, even in the face of martial arts masters whose personal strength is obviously higher, they are not afraid, the more masters we send, the greater the losses." ”

And the other party's main general, Shi Ziling, has not made a move at all, and he hasn't even seen a figure, only Xiahou Yuan's father and son, Bai Wuya and others are supervising the battle on the city tower. ”

Li Yuan, who was feeling anxious, was keenly aware of something strange after listening to Li Zhun's report, under the situation that he personally supervised the siege of the city all night, even if Shi Ziling did not take action in person, at least he should sit on the city tower. However, according to the report of his subordinates, there was no figure of Shiziling on the city tower, which seemed very unreasonable.

Li Yuan hurriedly found a number of wounded people who had climbed the city tower and questioned them carefully, all of them said that they had never seen Shiziling at all, and Li Yuan finally couldn't help but smile at the sky after hearing it.

Li Zhun said inexplicably: "Big brother, we have made no progress since the morning, and we have killed and injured many soldiers and martial arts masters, ...... How can you still laugh?"

Li Yuan sneered again and again: "I have asked carefully just now, from morning to now, all the people who have climbed the city tower have not seen Shiziling appear, don't you understand?"

Li Zhun's eyes lit up and exclaimed, "Could it be that the eldest brother means that Shiziling is not in the Black Dragon City at all?"

Li Yuan said coldly: "That's right. Shi Ziling must have quietly passed through our camp to connect with the reinforcements of his Songhu Army and Nangong Xia, in order to agree on the time and strategy to flank us before and after. Hmph, it's a pity that I saw through his tricks on the first night! I ordered the good hands of Tianlong Hall, Tianhu Hall and Tianbiao Hall to come with me, and we will take Black Dragon City in one fell swoop tonight. ”

The news that Li Yuan was going to lead the team to personally attack the city quickly spread throughout the entire legion, and all the soldiers and soldiers were naturally extremely excited.

Prior to this, Li Yuan only had a personal attack on Yanzhao Pass when he launched a general attack, and that time under his leadership, after a hard battle all night, he killed and injured countless masters of the Xiahou family, and finally succeeded in lowering the drawbridge of Yanzhao Pass, so that Li Yuan's army was finally able to successfully conquer Yanzhao Pass.

After the successive siege setbacks, the morale of Li Yuan's army was repeatedly hit, and the officers and men in the army had long been expecting their invincible sect leader to personally take action to raise the prestige of the army.

The most excited was actually Li Yuan himself, he did feel a little helpless after experiencing a long period of anxiety, but at this time he realized that Shi Ziling was not in the Black Dragon City.

Li Yuanzhi said that this is a great opportunity, as long as he uses his peerless magic skills to open a bloody path, once he opens the gap in Black Dragon City, with their absolute superiority in strength, no matter how good Shi Ziling's special attack division is, it will not be able to stop his 80,000 army from taking Black Dragon City.

For Li Yuan, although Bai Wuya and Xiahou Yuan are also today's top masters, they are not in his eyes, and the only thing that can really stop him is Shiziling. Since Shi Ziling is not in the city now, how can he let go of such a great opportunity.

Amidst the shouts and cheers of many soldiers and soldiers, Li Yuan led a group of martial arts masters in the Tongtian Sect to attack the tower of Black Dragon City. For Li Yuan, the walls of Black Dragon City were not too steep, and the flying stone arrows captured on the city were not too threatening, and he soon easily jumped up to the city tower with the help of a cloud ladder.

After Li Yuan raised his hand and knocked down the defenders of several special attack divisions in front of him, he stood on the city tower and shouted: "Tongtian Sect Master Li Yuan is here, whoever stands in my way will die! Black Dragon City will be mine from now on, if you don't want to die, run for your life quickly......"

Li Yuan's loud shouts shook the ears of everyone on the tower of Black Dragon City, and all the defenders were shocked, and they didn't expect that Li Yuan, the peerless hero of the world, suddenly appeared on top of the city tower.

Xiahou Yuan's father and son, Bai Wuya and others have been supervising the battle at the head of the city since the morning, and the defensive ability of the special attack division has indeed opened their eyes, with the cooperation of the skilled team of the soldiers of the special attack division, the same arrows, flying stones and rolling wood seem to be greatly powerful, and the killing efficiency of the siege enemy is also greatly enhanced.

Even in the face of Tongtian Sect masters who are stronger in personal ability, the special attack division will immediately form large and small Optimus Prime defensive formations and launch a siege on these martial arts masters who have ascended the castle tower. Under the efficient and tight defense of the soldiers of the special attack division, the siege team of Li Yuan's army suffered heavy losses, while the special attack division suffered few casualties.

Xiahou Yuan's father and son were originally a little worried that the defensive pressure of the special attack division would be great after Shi Ziling left, but who knew that the performance of the special attack division was far above their expectations, and they couldn't help but be surprised.

After the special attack division easily repelled wave after wave of attacks from Li Yuan's army, Xiahou Yuan's father and son had already put their minds at ease, and it was not unusual to expect that with the performance of the special attack division, not to mention five days, it would be not unusual to hold fifteen days or even longer.

They were particularly surprised by Optimus Prime's defensive formation, which could be large or small, from three or five sergeants to a large-scale defensive formation of dozens or even hundreds of people, even in the face of masters whose personal strength was much higher than their own.

Although Li Yuan used the advantage of his strength to use the wheel tactics to attack the city all night, the special attack division's defense efficiency was extremely high, and it did not require all the men and horses to sleep endlessly, but were divided into two shifts of men and horses to take turns to rest, and they could easily deal with the wheel battle of Li Yuan's army.

Just when Xiahou Yuan and the others felt that the situation was very good, Li Yuan's break suddenly woke them up. When they realized that it was Li Yuan who had personally attacked, Li Yuan had already knocked down a large number of defenders of the Special Attack Division with a wave of his hand, and many martial arts masters of the Tongtian Sect had also climbed the city tower one after another.

Xiahou Yuan and Bai Wuya's hearts shook at the same time, but they didn't expect that the scene that the two of them were most worried about had been staged on the first day after Shi Ziling left. Li Yuan somehow knew that Shiziling was not in the city, and he had personally attacked the city tower so quickly.
