Although H city is not a big city in the country, but at least it can be regarded as a medium-sized city, covering a considerable area, and wants a treasure that can protect the entire H city, which is definitely not a general product.

This treasure is the lowest seven order, and because it can be protected on a large scale, the value is even more than the general eighth-order treasure.

If it is something else, it cannot be changed at all, but the heart of the sacred stone is an exception, and this thing is worth more than the treasure of protecting the city!

Dan Mo mused a little, came up with something that looks like a crystal ball: "This is an anaonic ion protection system, covering a radius of 50 kilometers, can withstand all the attacks below the seventh order, even the eighth order strong can withstand a period of time, this thing will usually absorb free energy, only in the event of attack need to replenish energy, this should be able to change your holy stone heart?" 」

Wu Feng did not speak, but others were luminous, and the protection system was really too strong.

Although the coverage is not large, but can cover the whole city of H, the most critical is to be able to resist all the attacks below the seventh order, but also to resist a moment of eight orders of attack, to know that at this time on the earth, the most powerful is only the existence of the sixth order, this is still the mutant animal side.

In this way, H city is equivalent to Jintang, no one can break the defense of H city, but also here will become the safest city in the world.

But Wu Feng shook his head: "This is not enough."

Dan Mo stared at Wu Feng: "The price of the heart of the sacred stone is indeed very high, but this thing has only one effect, if it is not too rare, it is not as practical as the protective system in my hand."

"It is not so true that, of course, the sale of things depends on all values, no matter which merchant it is, the heart of the stone in my hand is higher than the value of the protective system in your hand, and if the transaction is not equal, I think there is no need to continue the transaction."He said, Wu Feng was ready to put away the heart of the holy stone.

“Wait!”Danme hastened to prevent that there was no such thing as the heart of the holy stone in his hand, which was definitely a treasure, and even if it was collected, the value was immeasurable.

He bit his teeth as if to make up some determination: "I use this protective system plus a light energy particle gun, this can do it."

The next second, a small-looking high-tech cannon appeared in his other hand, which is really offensive and defensive.

“What is the effect of this light-energy particle gun?”Zheng Gang asked.

"One shot down, the sixth order of death is not a problem, but this thing consumes a little more, kill a sixth order, you must have ten six-order energy crystals, if you want to kill the seventh order, then you must have ten seventh-order energy crystals."

“What about the 8th grade?”Zheng Gang hurriedly asked.

“Are you dreaming that the eighth order is so easy to be killed?”Dan Mo Bai glanced at him.

Even so, the power of the particle cannon is surprising, which is definitely the bottom card of the H city.

“The transaction.”Wu Feng laughed.

The Heart of the Sacred Stone in Wu Feng is just a prop that can bring him back to Earth, and there is no other use, and if it can be exchanged for something that protects H City, it is absolutely cost-effective.

Dan Mo happily accepted the heart of the holy stone, which was something he had always wanted to get, but unfortunately he did not have this luck, he could not find it without saying it, and no one could trade with him with this kind of thing, and today he finally got it.

“Next time you have something good, come back to me.”Dan Mo beckoned to Wu Feng and left here.

Wu Feng looked at the two things in his hand, he handed the anionic protection system to Yu Xuefei, as the agent of the city and she was still the waiter of Wu Feng's store, and it was reasonable to give this to her.

As for another light energy particle cannon, he thought about it and gave it to Zheng Gang.

Zheng Gang has followed his brother from the end of the world to the present, the two are really over-life, and he knows that Zheng Gang looks a little frimp, but his heart is still very stable, this weapon is handed to him, Wu Feng is also relieved.

“Sister Shelby, how do you use this?”Todd went curious and asked.

"It's like a drop of blood."Yu Xuefei bit her finger, and a drop of bright red blooddropped from her finger fell into the protective system.

A light flashed, Yu Xuefei found that he had a 3D map in his head, and a mechanical voice said: "The anion protection system starts, the system certification, the binding system user Yu Xuefei, please set the center point of the system."

Yu Xuefei reacted quickly, knowing that this is the protective system, and the sound should also come from here.

“Set the center of the system in downtown H and use the center to expand the protection system.”Yushu Fei ordered.

“The center of the system is set up successfully, and the system is unfolding...

Yu Xuefei was able to clearly "see", and a light film appeared above the map in his own mind, surrounding the entire city of H.

At the same time, the patrolmen who were on the border of H City found that a pale blue film had fallen from the sky, enveloped them, frightening them to think that something was happening again, and hurried to report the matter.

Some bold people gently touched this light film with their weapons in their hands, and did not break through this thin-looking film of light, making them embarrassed and did not know what was happening.

"Please set personnel permissions."The protective system says.

As long as the people set up by Yu Xuefei, they can enter and exit the protective system at will, and the people who have not been set up, even if they are mutated animals and aliens, they cannot enter.

In other words, this is equivalent to an alien detection machine, so that the city of H no longer needs to use blood paper.

Suddenly Yu Xuefei's heart moved: "Can you detect the existence of a zombie?"

Soon, Yu Xuefei saw a lot of red spots on the map, and she knew that these were the zombies in H city.

Wu Jinming and others are humanoid zombies she has long known, but their number is only 18, but on this, the number of red dots is at least a hundred!

"I didn't expect that there were so many humanoid zombies in H City, what intention did they have, or did they say that they were like Wu Jinming?"Yu Xuefei couldn't figure it out, but she didn't bother to think about it, as long as she caught these human zombies to know the reason for all.

Subsequently, Yu Xuefei marked all the other people except the zombies as ordinary permissions, and she set Wu Feng as the highest authority, she and Zheng Gang and others are the first level of permission, the higher the permission, you can carry out various operations on the protection system.
