In fact, the reason why Yong'an County's city protection array became like this is naturally related to Xia Fan.

When it was decided to use Yong'an County as the front fort to attack the Han Dynasty, Xia Fan and others took into account the problem of the city protection array, and later Zhao Weiwei and Liu Yu Linglong never forgot this matter, and privately asked Jia Yansong to transform the city protection array under the pretext of similar to the renovation of the city wall and the maintenance of the city protection array.

How to transform it is Xia Fan's suggestion, the principle is that when the city protection array is in the hands of others, they can easily break it and enter, and when it is in their own hands, then they can firmly block the enemy out. The specific transformation was done by Jinsuo.

For this reason, Zhao Weiwei and Liu Yulinglong went to Yunhuanhu Lake to invite the formation during that time. Of course, their efforts were not in vain, and the transformed city protection array was indeed extraordinary.

It stands to reason that when it comes to the changes to the city protection array, Jia Yansong has to apply to the head in advance to report to his body, but he didn't do so, so that the transformation part of the city protection formation construction drawings obtained by those formation mages is not visible at all.

This also makes it completely impossible for them to find the breaking formation of the city protection array through the drawings, and of course they have to plant a big heel fight on it.

In fact, just by virtue of Xia Fan's idea, the formation suo personally transformed these two points, which is equivalent to two formation masters joining forces to set up the formation, where are these ordinary formations that can be handled, and it is strange not to touch a face full of blood.

Previously, Zhao Weiwei and Liu Yu Linglong were confident that they could defend this Yong'an County City with 50,000 soldiers and horses, in addition to the great confidence given to them by Xia Fan sitting in the city, part of the reason was that they believed that this large array of city protectors was not so easy to destroy.

In the face of such an indestructible and not even an obvious flaw, the hearts of these array mages who were ordered to break the formation were desperate, but the military orders were like a mountain, and they had no way to retreat, so they could only bite the bullet.

"Bang ......" is just a brutal result, and after the loud noise, two people died tragically under the counterattack of the formation.

At this moment, the mages of the sub-array were completely numb. They didn't dare not break the formation, otherwise it would be a capital crime to disobey the military order, but they knew that if they broke the formation like this, it would also be a dead end.

"Why hasn't the city protection array been broken yet?" Cao Shiping saw that the city protection array had not been destroyed for a long time, and then asked in a deep voice.

"Report to Prime Minister Zuo, Yong'an County's protective array has been modified, and now it is difficult to find a flaw, if you want to break it, it is not something that a formation mage can do at all, at least it must be a strong person in the Grandmaster Realm. Someone replied.

"In this case, I also asked Lu Dadu to help, and the prime minister thanked him in advance. Cao Shiping looked at the person who had been following him and said.

Although this person is in the army at this time, he is not in armor, but is wearing the clothes of the Qianlong Guard, which is a major commander of the Qianlong Guard, named Lu Fanglin, who is about fifty years old, and has the strength of the peak of the God Realm.

His qualifications in the Hidden Dragon Guard are very high, but because he has not been able to break through to the Grandmaster Realm for a long time, he has never been able to be promoted to the Great General of the Hidden Dragon Guard. I have been a metropolitan leader for more than 20 years.

This time, Liu Xingchen ordered Cao Shiping to come down, naturally it was impossible to trust him wholeheartedly, and sent dozens of hidden dragon guards led by Lu Fanglin to follow, nominally to protect Cao Shiping's safety, but in fact he was supervising him.

If Cao Shipingyang disobeys or does not do well, even if he is the left minister, Lu Fanglin can directly dismiss him from office, and then bring him back to the capital to wait for the emperor to deal with it.

It was precisely because of the existence of Lu Fanglin and others that when he learned that Zhao Weiwei and Liu Yulinglong had killed Hu Mingzhi, Cao Shiping immediately summoned soldiers and horses to exterminate him. He was also worried about being charged with dereliction of duty by Mr. Lu.

Usually Cao Shiping and Lu Fanglin don't have anything to say, and most of the time they treat it as air, but now that they are in trouble during the siege, they naturally ask him for it.

It stands to reason that Cao Shiping, who is the left minister, must be higher than Lu Fanglin, the hidden dragon capital, in terms of official position, and there is no need to be so polite to him.

But Cao Shiping is demanding after all, and at the same time, Lu Fanglin is the capital of the Qianlong Guard, which is trusted by the emperor, so his attitude towards him is naturally different.

"Lord Zuo Xiang doesn't need to be polite, you and I are loyal to the emperor, and when you encounter difficulties, you should work together to tide over the difficulties, and please wait for a while, and I will break the big array of the city protection." Lu Fanglin said politely, but he was secretly proud in his heart, and said in his heart: You have brought so many soldiers and horses, but they are all waste, and in the end, you have to ask for the head of our hidden dragon guard.

Smug, but Lu Fanglin was not careless at all when he stood in front of the city protection array.

With his knowledge and eyesight, it was not difficult to see that the great array in front of him was not simple, and the thickness of its formation aura was not much worse than that of some small cultivation sects.

"It's no wonder that these soldiers and horses under Cao Shiping have been attacking for so long and have not been able to break through this mountain protection array, but with me, I can naturally solve it. Lu Fanglin thought in his heart, he had already sacrificed his magic weapon.

It's an armor-piercing cone. The front end of this object is sharp and destructive, and it can easily destroy the thick and heavy armor that the enemy wears, hence the name.

After refining it into a magic weapon, it not only has strong attack power, but also has strong penetrating power, especially when attacking enemies with extremely strong defense, it can often achieve twice the result with half the effort. Lu Fanglin used this magic weapon to kill many strong enemies and made many contributions.

He dared to agree to Cao Shiping's request, and he was full of confidence in his heart, all because he had such a magic weapon in his hand.

"Woo......" After Lu Fanglin sacrificed the armor-piercing cone, he launched an attack after charging his strength.

With a piercing whistling sound, the armor-piercing cone turned into a dazzling light, swept across the sky and blasted straight towards the main protective array.

Because the armor-piercing cone was so eye-catching, it attracted the attention of almost everyone on the battlefield.

The army of the Han Dynasty was naturally extremely excited when they saw it, hoping that they could blast the city in one fell swoop, and then they could take advantage of the situation to enter Yong'an County and kill all the traitors among them.

But the defenders at the head of the city were frightened, angry, and worried. Because they knew very well that if this thing really broke the protective array, it would be an extremely bitter battle waiting for them.

"I'll go, what should I do?!" Jia Yansong, who was standing at the head of the city, saw this scene, and couldn't help but swear in his heart, because he really didn't expect the enemy to be able to attack the city in such a way. It's cheating!

The light of the "Boom ......" armor-piercing cone came quickly, and instantly collided with the aura of the city protection array, and the violent shock in the deafening explosion then spread in all directions.

The ground shook, and at the same time, the city wall trembled a few times, which showed how powerful the blow of the armor-piercing cone was.

But when the violent shock wave dissipated, everyone realized that although the attack of the armor-piercing cone was fierce, it was nothing more, and under the previous onslaught, it did not break the protective array at all.

Even the aura on the protective array didn't seem to be affected much in the slightest, and it was still as thick and bright as before. The only thing that could make people feel that Fang had just experienced a violent attack was that the surrounding heaven and earth aura was now converging towards the Great Array of Protectors.

Obviously, the blow just now still caused some impact on the Great Array of Protectors, so it was gathering the aura of heaven and earth on its own to replenish the aura consumption caused by the attack against the armor-piercing cone just now.

"Damn, what's going on?, under the blow of my armor-piercing cone, even the magic weapon of the Nine Levels of the Divine Spirit Realm can be exploded, even a mountain can be blasted through, how can I not break through this protective array?!" When Lu Fanglin was shocked in his heart, he felt that his cheeks were even hotter.

How confident he was in himself just now, how wasteful he felt about the army brought by Cao Shiping, and how embarrassed and embarrassed he felt now.

The only thing that made him glad was that he didn't blow out the big words just now, otherwise, it would be really embarrassing.

However, when Lu Fanglin remembered that he had told Cao Shiping that he would be able to break the formation if he stayed for a while, his cheeks couldn't help but feel hot again.

"Boom ......" In order to regain face as soon as possible, Lu Fanglin suddenly broke out with all his strength, and once again urged the armor-breaking cone to slam on the top of the city protection array.

The tremors caused by the collision were even more violent, so that some of the defenders at the head of the city were unstable and almost fell from the top of the city, but they still failed to break through the protective array.

"How can this be?!" Seeing this scene, Lu Fanglin was shocked and angry, especially when he noticed the disappointed eyes of his soldiers when they looked at him.

"No matter what, we must break this protective array, otherwise my face will be completely lost!" As soon as he thought of this, Lu Fanglin was also completely relieved, reached out and took out a dark red pill, and finally swallowed it after a little hesitation.

This elixir was refined by the alchemists in the Hidden Dragon Guard, which could maximize the potential of the person taking it, causing its strength to skyrocket in a short period of time. However, it has no effect on the powerhouses of the Grandmaster Realm.

For example, Lu Fanglin himself had the strength of the peak of the Divine Spirit Realm, and after taking this pill, he even burst out of the strength of the early stage of the Grandmaster Realm in a short period of time. The effect can be described as powerful, but the consequences of this are also very serious, that is, his vitality will be damaged because of this, and he will have to recuperate for at least a year to recover.

Lu Fanglin carried this elixir with him, which was originally intended to be used to save his life when encountering a strong enemy that was difficult to deal with, but now he was already difficult to ride a tiger.

If he can't break this great array today, then even if his old face is lost, maybe it will affect the prestige of the Hidden Dragon Guard.

What's worse is that if you can't break this protective array, then you won't be able to conquer Yong'an County, and naturally you can't exterminate Zhao Weiwei, Liu Yulinglong and other rebels.
