Such lightning attacks can still be withstood by strong people of level 4 and level 4, but those of level 3 and level 3 cannot withstand the thunderstorm attacks and will be killed by lightning in a very short time.

With such a magic circle, it will cause huge damage to enemies with a large number but not strong enough.

But just such a range attack is of course not enough.

Therefore, in Zhang Cheng's plan, the real attack method is still a long-range magic cannon.

Zhang Cheng once obtained a magic cannon, but the level of that magic cannon is too low and its power is relatively weak. In this battle, this magic cannon also exerted considerable power. Unfortunately, the level of the magic cannon has always been too low, which leads to such magic cannons not playing a big role in a truly high-end battlefield.

But with this magic cannon, Zhang Cheng can create his own magic cannon.

Zhang Cheng had a brand new design drawing of a magic cannon in his heart, but he had not made this magic cannon yet.

According to Zhang Cheng's calculations, magic cannons are also divided into two types: one is a mobile turret and the other is a fixed turret.

The mobile turret has high maneuverability, but it also lands in power, and its power is somewhat not strong enough.

But the fixed turret is different.

The fixed turret is combined with the magic circle, and the magic power of the magic cannon also comes from the magic circle. In this case, the power of this magic cannon will be very huge.

Zhang Cheng named this fixed magic cannon the Divine Power World Destroying Cannon.

This is a very majestic name. Similarly, matching the name, of course, the huge power of this divine power cannon.

The power of the Divine Power World-Destroying Cannon with one shot is equivalent to the high-level fifth-level magic. The power of the Divine Power World-Destroying Cannon is not yet at the sixth level, but it is already the top level of the fifth level, which is not much different from the sixth level.

The sixth-level magic power is already an additional law in it, which is the special feature of the sixth-level magic.

The power of the Divine Power World-Destroying Cannon has reached the sixth level, but because it lacks the power of law, it can only be regarded as the fifth-level magic.

With such divine power, Qinglong City can only be left behind.

Although there is only one, it is definitely enough to use it.

This is because the Divine Power World-Destroying Cannon can attack continuously.

You should know that it is also very difficult for a fifth-level magician to cast a fifth-level magic attack.

For a fifth-level magician, casting a fifth-level magic will consume a lot of his magic power and mental power. Each time he casts, he must rest for a while before he casts the second spell, and he cannot continuously cast the fifth-level magic.

However, the Divine Power World-Destroying Cannon can launch magic attacks continuously, and all fifth-level magic attacks come. Tell me, how many people can withstand such magic attacks?

Needless to say, take this battle as an example. If there were also Divine Power Destroying Cannons to attack this battle, Zhang Cheng and the others would have driven the other party away long ago.

In addition to the fixed magic cannons, there are also moving magic cannons. The moving magic cannons are not that powerful, but they can also be used to deal with fifth-level powerful people.

This is Zhang Cheng's re-planning of the defensive power of Qinglong City. It is not easy to achieve this goal.

After learning about this situation, Zhang Cheng gave up the idea of ​​completing the magic array immediately. First, he strengthened and repaired the magic array so that the existing magic array could still work, but the rest can be completed slowly in the next time.

After spending a day to complete the restoration of the magic circle, Zhang Cheng summoned all the existing troops the next day.

The number of soldiers under Zhang Cheng's men has increased to 5,000. Although the number is quite large, to be honest, there are not many people with combat effectiveness, and if the battle really occurs, they will not play much role.

In this battle, this legion did not play much role.

Of course, this is not something that can be blamed on them. On the one hand, their strength is too weak, and on the other hand, it is also because their opponents are too strong. Looking at the retreating strong enemy, Zhang Cheng was relieved and did not continue to pursue.

In fact, even if Zhang Cheng wants to pursue him, it is impossible. After all, Zhang Cheng's own strength is still not as strong as the other party. The other party retreated because he saw the actual situation and knew that he would continue to fight, he would not have much benefit to his side, so he gave up.

The battle was finally over. Although Zhang Cheng had little casualties, there were no injuries after the battle.

However, compared with the situation after the city was broken, the current situation is already considered good, and it cannot be better.

The aftermath work after the battle did not require Zhang Cheng to deal with it, and Zhang Cheng immediately took back that he was the guardian of despair.

Zhang Cheng left only one of the twelve desperate guards for research, and the remaining desperate guards were all placed on the city wall. This is a deterrent force, but if necessary, it can become a super powerful attack force.

Although this battle suffered a great loss, it also gained a lot.

I won’t talk about the material gains for now. For Zhang Cheng, after this battle, Zhang Cheng also had a clearer understanding of the defensive power of Qinglong City.

Before, Zhang Cheng thought that Qinglong City's defense was strong enough, and he could leave Qinglong City with confidence and go out for adventure, but after just one battle, Qinglong City was almost broken, so Zhang Cheng probably overestimated the defense power of Qinglong City too much.

The defensive power of Qinglong City is already an extremely powerful force for ordinary forces, but for the Horn Tribe, Blood Axe Tribe, and Canglang Tribe, it is simply not a powerful thing. As long as they spend more time, they can crack down on Qinglong City's defense.

Therefore, Zhang Cheng was also determined to rebuild the defensive layout of Qinglong City and greatly improve the defensive power of Qinglong City. Even if he encounters more powerful forces to attack Qinglong City in the future, he must ensure the safety of Qinglong City.

It was also because of this idea that Zhang Cheng immediately began to study the defensive power of Qinglong City.

The defensive power of Qinglong City is sufficient by two parts, one is the defensive magic shield, and the other is the attacking magic array.

One is responsible for offense and the other is responsible for defense.

This is the main defensive force of Qinglong City.

As a city stronghold, if you only have magic defense shields, it is absolutely not enough, because a city that can only be beaten passively cannot last long. No matter how powerful the defense is, it will be broken for one day.

Therefore, the best defensive force is considered to be the best defensive force.

The first thing Zhang Cheng has to do is to improve Qinglong City’s defensive power.

There was no problem with the previous defensive magic shield itself, but Zhang Cheng also found that his thinking was still somewhat restricted.

Defense does not necessarily have to be near the city, and defense does not necessarily have to be simply defense.

After thinking about it, Zhang Cheng had a brand new idea.

First of all, this defensive cover is divided into three layers, and the first layer protects within a range of 100 kilometers around Qinglong City.

Within a 100-kilometer radius of Qinglong City, it will be covered by huge defensive magic shields.

The defensive power of this defensive magic array is not particularly powerful, because the range is too large and it cannot support such a powerful magic shield.

Therefore, the main function of the first defensive shield is to block the enemy and act as an alarm, and to block the incoming enemy at the first time.

The second layer of magic shield is arranged thirty kilometers away from Qinglong City. After the first shield is broken, the second shield will automatically be erected to protect the safety of the city.

Because the defense power of the second shield is already stronger than the first shield, the role it can play is even greater. According to Zhang Cheng's calculation, the defense power of this shield will be more than twice the defense power of the first shield, and such a defensive power is quite considerable.

Of course, in actual combat, such a shield may not be able to withstand the powerful attacks of these people, so the second shield also plays a buffering role. It does not have to face the attack of powerful enemies at the first time, so it can give you time to prepare.

The third shield is the real thing to protect the safety of this city.

The third magic shield will only cover the area around Qinglong City. The distance between the shield and the city wall is one kilometer. This distance can be said to be a very short distance. Almost as long as the shield is broken, you can enter Qinglong City immediately.

However, the reduced shield also represents a powerful defensive force.

According to Zhang Cheng's plan, this shield will be composed of a combined group of one hundred mage towers. Once it is activated, it will be able to withstand the attack of sixth-level magic.

Zhang Cheng has never seen the sixth-level magic, but he can still estimate the power of the sixth-level magic.

Even the sixth-level magic can be resisted, so those who resist the attack of the fifth-level magic are of course nothing.

Of course, if it is just defense, then you will underestimate the magic circle arranged by Zhang Cheng.

The real magic circle is powerful, but it can reflect attacks.

The sixth-level magic attack will rebound half of the power in the magic circle, which means it can rebound fifty percent of the magic attack.

If it were a fifth-level magic attack, it would have 70% of the magic power, and all of them would be bounced back.

The power of the fifth-level magic is 70% quite scary.

Seventy percent of the attacks that rebound will hit you, and it will also pose a fatal threat to you.

And when it comes to the fourth-level magic, the effect is even more amazing.

The fourth-level magic can already achieve 90% reflection ability, and almost reflect the magic back as it is, only shrinking by one tenth.

If magic attacks below level 4 are hit by this magic shield, they will be reflected back 100%.

Although these magical attacks were released by the magician themselves, they still pose a great threat to themselves after being reflected back.

Facing such a magic shield, no magician can still cast magic with peace of mind.

The characteristic of a magician is that his defense is weak, but his attack power is very strong. Therefore, if the magic attacks they emit hit him, they will probably kill him.

From this point of view, we can see how powerful and insidious the magic array designed by Zhang Cheng is.

Especially when facing such a magician with magic shield for the first time, I will definitely suffer a big loss.

This is the defensive magic shield that will be built in this Qinglong City later.

Defense is only part of it, but what can truly resist the enemy's attack is still the offensive force.

Therefore, in the defense of Qinglong City, what Zhang Cheng cares about most is the offensive power.

Zhang Cheng took two measures to attack. One is a magic array. The magic array is used to attack a large-scale attack. When targeting a large number of enemies, Zhang Cheng chose a thunder and lightning magic array. Once opened, it can cause thunderstorms within a range of more than 100 kilometers. Thunderstorms do not directly produce thunder and lightning attacks. However, in this weather, the entire area is like a gasoline barrel. Just a little lightning is needed to detonate the entire area, thereby triggering a terrible lightning attack.

But this situation is not so good for Zhang Cheng.

Zhang Cheng wanted these troops, but he also hoped that they could play their role, but the current situation is that they could not play their role at all.

It is obviously impossible to improve their strength in a short period of time, but there is still a way to improve their combat effectiveness.

This method is very simple to say, and you only need to provide more powerful weapons and equipment for these soldiers.

Of course, to improve their combat effectiveness, they naturally cannot provide ordinary equipment. They must have powerful magic equipment to improve their combat effectiveness.

Although Zhang Cheng was able to create magic equipment, he had to create some simple magic equipment because of the lack of magic materials before, but he had not had time to create truly powerful magic equipment.

But this time, Zhang Cheng had already obtained these magic materials, so he could naturally create powerful magic equipment.
