In fact, the reason why the city-shackle formation in Yong'an County became like this is naturally related to Xia Fan.

When he decided to use Yong'an County as the forefront to attack the Han Dynasty, Xia Fan and others considered the issue of the city-mopping formation. Later, Zhao Wei and Liu Yulinglong never forgot about this matter. They privately asked Jia Yansong to transform the city-mopping formation under excuses such as renovation of the city wall, maintenance of the city-mopping formation, etc.

How to transform is the advice given by Xia Fan. The principle is that when the city protection formation is in the hands of others, they can easily break it into it, and when it reaches their own hands, they can firmly block the enemy. The specific transformation is done by the formation elder.

For this reason, Zhao Wei and Liu Yulinglong often went to Yunhuanhu to invite the formation master. Of course, their efforts were not in vain, and the transformed city-sharing formation was indeed extremely powerful.

Logically speaking, when it comes to changes to the city-mould formation, Jia Yansong had to apply to the Shangtou in advance to report, but he did not do so, so that the modified part could not be seen on the drawings of the city-mould formations obtained by the formation masters.

This also makes it impossible for them to find the breaking formation of the city-shaking formation through the drawings, and of course they have to fall into a big fight here.

In fact, just by Xia Fan's idea, the formation elder personally transformed these two points, which is equivalent to two formation masters working together to set up the formation. How could these ordinary formations be able to cope with? It would be strange if they didn't touch the blood on their faces.

Previously, Zhao Wei and Liu Yulinglong were confident that they could use 50,000 troops to defend the Yong'an County City. In addition to giving them great confidence because Xia Fan was in charge of the city, there was also part of the reason that they believed that this city-mopping formation was not so easy to destroy.

Faced with such an indestructible formation that was not even a clear flaw, the formation masters who were ordered to break the formation were desperate in their hearts, but the military orders were as strong as a mountain, and they could not retreat, so they could only bite the bullet and force it.

"Bang..." The result of just being reckless was that after a loud noise, two people died tragically under the counterattack of the formation.

Now the formation mages were completely numb. They dared not not to break the formation, otherwise it would be a death sentence to disobeying the military order, but they also knew that breaking the formation in this way would be a dead end.

"Why has the city moat formation not been broken yet?" Cao Shiping asked in a deep voice when he saw that the city moat formation had not been destroyed for a long time.

"Report to the left prime minister, the city-shackle formation of Yong'an County has been changed, and it is difficult to find flaws now. If you want to break it, it is not something that the formation master can do. At least it must be a powerful person in the Grandmaster realm." Someone replied.

"Since that's the case, please ask President Lu to help. I thank you first." Cao Shiping looked at the person who had been following him and bowed.

Although this person was in the army at this time, he did not have armor on his body. Instead, he was wearing the costumes of Qianlong Guard. He was a general of Qianlong Guard, named Lu Fanglin. He was about fifty years old and had the strength of the peak of the Divine Realm.

He has a high qualification in Qianlong Guard, but because he has not been able to break through to the Grand Master Realm, he has never been promoted to General Qianlong Guard. He has been a general of the capital for more than 20 years.

This time, Liu Xingchen issued an order to send Cao Shiping down, so it was naturally impossible to trust him wholeheartedly. He sent dozens of Qianlong Guards headed by Lu Fanglin to follow him. In name, it was to protect Cao Shiping's safety, but in fact it was supervising him.

If Cao Shiping disobeyed or did not do anything well, even if he was the left prime minister, Lu Fanglin could directly dismiss him from office and then take him back to the capital to wait for the emperor to deal with him.

It was precisely because of the existence of Lu Fanglin and others that when they learned that Zhao Wei and Liu Yulinglong had killed Hu Mingzhi, Cao Shiping immediately summoned troops to wipe out. He was also worried that Lu Fanglin would be detained as guilty of neglect of duty.

Usually, Cao Shiping and Lu Fanglin didn't say anything, and most of the time they treated it as air, but now when they encountered trouble when siege, they naturally asked him to come to his head.

Logically speaking, Cao Shiping, as the left prime minister, must be higher than Lu Fanglin, the Qianlong Metropolitan, in his official position, and there is no need to be so polite to him.

But Cao Shiping had something to ask for, and Lu Fanglin was the general of Qianlong Guard trusted by the emperor, so his attitude towards him was naturally different.

"Lord Zuo Prime Minister doesn't need to be polite. You and I are all loyal to the emperor. When encountering difficulties, you should work together to overcome difficulties. Please wait for a moment. I will defeat the city protection formation." Lu Fanglin said politely, but he was secretly proud in his heart. He said: You have brought so many soldiers but they are all useless, and in the end you have to ask for our Qianlong Guard.

He was proud, but Lu Fanglin was not careless when he stood in front of the city moat formation.

With his knowledge and eyesight, it is not difficult to see that the city protection formation in front of him is not simple, and the thickness of its formation aura is no less than that of the mountain protection formation of some small cultivation sects.

"No wonder the soldiers and horses under Cao Shiping have been attacking for so long but have not been able to break the mountain protection formation. But with me, I can naturally solve it." Lu Fanglin thought to himself, and had already sacrificed his magic weapon.

This is an armor-breaking cone. The front end of this object is sharp and has great destructive power. It can easily destroy the thick and heavy armor hanging on the enemy's body, so it has this name.

After refining it into a magic weapon, it not only has strong attack power, but also has strong penetration 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 powerful enemies and made many contributions.

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

"Woo..." After Lu Fanglin raised the armor-breaking cone, he activated his attack after a little energy.

Amid the harsh roar, the armor-breaking cone turned into a dazzling light, swept across the sky and blasted straight towards the city-shaking formation.

Because this armor-breaking cone is too eye-catching, it attracts almost everyone on the battlefield.

The army of the Han Dynasty was naturally extremely excited when they saw it, hoping that it could explode the city-mopping formation in one fell swoop, and then they could go into Yong'an County and kill all the thieves.

But the defenders on the top of the city were shocked, angry and worried. Because they knew very well that if this thing really exploded the city-defense formation, what awaited them would definitely be a fierce and bitter battle.

"I'll go, what should I do?!" Jia Yansong, who was standing on the top of the city, couldn't help but swear in his heart when he saw this because he really didn't expect the enemy to use this method to attack the city. This was simply cheating!

"Boom..." The light transformed from the armor-breaking cone came quickly and instantly collided with the spiritual light of the city-shaking formation. The violent shock of the deafening explosion spread to all directions.

The ground was shaking continuously, and the city walls were trembling a few times, which showed how powerful the armor-breaking cone was.

However, when the fierce shock wave dissipated, everyone realized that although the armor-breaking cone was very strong, it was nothing more than that. After the previous collision, the city-shake did not break the city-shake formation at all.

Even the spiritual light on the city-mould formation did not seem to be affected much, and was still as thick and bright as before. The only thing that makes people feel that they have experienced a fierce attack is that the spiritual energy around the world is gathering towards the city-mould formation.

Obviously, the attack just now still had some impact on the city-shaking formation, so it was gathering the spiritual energy of heaven and earth on its own to supplement the consumption of spiritual energy caused by the attack against the armor-breaking cone just now.

"Damn, what's going on? With the attack of the armor-breaking cone, I can even explode the magic weapon of the ninth level of the Divine Realm. Even if a mountain can be penetrated, how could I not break the city protection formation?!" Lu Fanglin felt even more shocked, and felt her cheeks were even hot.

Just now, he felt so confident in himself, and how useless the army brought by Cao Shiping, and now he felt so embarrassed and embarrassed.

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

However, when Lu Fanglin remembered that he had told Cao Shiping that he had let him break the formation for a while, his cheeks became hot again.

"Boom..." In order to regain face as soon as possible, Lu Fanglin suddenly burst out with all his strength, and once again activated the armor-breaking cone to hit the city-shaking formation.

The vibration caused by this collision was even more intense, so that some defenders on the city were unstable and almost fell from the city, but they still failed to break the city's moat formation.

"How could this happen?!" Seeing this scene, Lu Fanglin was shocked and angry, especially when he noticed his soldiers and generals looking at him with disappointed eyes, he felt even more ashamed and annoyed.

"No matter what? You must break the city protection formation, otherwise my face will be completely wiped out!" As soon as I thought of this, Lu Fanglin completely took it out and reached out to take out a dark red pill. After hesitating for a moment, hesitated and finally swallowed it.

This pill was refined by an alchemist in Qianlong Guard. It can maximize the potential of the user and make its strength soar in a short period of time. However, it has no effect on powerful people in the Grandmaster realm.

For example, Lu Fanglin himself has the strength of the peak of the Divine Realm. After taking this pill, he even burst out the strength of the early stage of the Grandmaster Realm in a short period of time. The effect is powerful, but the consequences are also very serious, that is, his vitality will be damaged, and at least he has to take good care of it for a year to recover.

Lu Fanglin carried this pill with him. He was originally planning to save his life when encountering a powerful enemy that was difficult to deal with, but now he is already in a difficult position.

If this city-protected formation cannot be broken today, even if his old face is completely lost, it may even implicate the reputation of Qianlong Guard.
