The zombie group composed of high-level zombies has attacked the city gate of the Beishan base, and the solid stainless steel gate can temporarily resist the attack of the zombies, as long as the zombies above the third level do not attack collectively, the gate of the Beishan base will not be breached.

The first-level and second-level zombies who took the lead have already gathered under the city gate of the Beishan base, and in the face of this low-level zombie, the people of the Beishan base are ready to use high-explosive grenades to deal with them.

The high-explosive grenades that fell vertically from the city walls fell like raindrops, and the dense explosions sounded under the city walls, and those first- and second-level zombies were torn apart by the high-explosive grenades.

These zombies seem to be different from the past, although the level of the first-level and second-level zombies is low, but the high-explosive grenade is normally unable to hurt them, the reason why they will be injured by the high-explosive grenade this time is naturally that Lin Feng found something unusual.

From the beginning of these zombies, Lin Feng found that there was a problem with the energy fluctuations on these zombies, under normal circumstances, the energy value of these first-level zombies should be more than one hundred, and the second-level zombies should be more than two hundred and three, but the energy value of these zombies is generally low, the energy value of the first-level zombies is only about sixty, and the second-level zombies are only about one hundred and fifty.

Within this value, the abilities and combat effectiveness of the first-level zombies and second-level zombies are reduced to a minimum, except that these zombies themselves are not humans, and the rest are exactly the same as humans, so these zombies will be easily killed by high-explosive grenades.

The zombies under the walls are still attacking, although the high-explosive grenades work, in the final analysis, it is only these zombies that have a problem.

"Chief, why are these zombies easily killed by high-explosive grenades, could it be that the power of high-explosive grenades has become greater?"

Manager Qian leaned over and saw the torn zombies that were blown up by the high-explosive grenade below, he never knew that the high-explosive grenade could kill low-level zombies, if he had known, those who went out hunting would not have been injured.

"It's not that the power of the high-explosive grenade has become greater, but the ability of these zombies has become lower, haven't you noticed that the speed and attack power of these zombies are different from before?"

Listening to Lin Feng's explanation, Manager Qian carefully observed the zombies under the city wall and the zombie group that continued to run in the distance.

Sure enough, the action of these zombies is indeed different from before, not to mention the low-level zombies at the moment, even the third-level zombies in the distance have slowed down, this situation has never happened, but Lin Feng can see the difference between the zombies in such a nervous attack, and he can also know that there is a problem with the energy value of the zombies, does Lin Feng still have hidden strength?

There are almost more than a hundred low-level zombies killed under the city wall at present, and there are still many low-level zombies in the back, and the high-level zombies behind are like being coerced, while looking behind, they quickly attack in the direction of the Beishan base.

The high-explosive grenades at the Beishan base are about to run out, and if the high-explosive grenades are gone, then the zombies gathering under the city wall will only cause a busy point, after all, heavy weapons cannot attack vertically under the city wall.

Unable to allow high-level zombies to reach the city gate, Lin Feng quickly launched an order, and the heavy weapon was ready to fire, targeting the group of zombies at a medium distance.

Starting from the dividing line of the zombie group at a medium distance, the high-level zombies in the back will be temporarily blocked in the distance, while the low-level zombies in the vicinity will be killed by the remaining high-explosive grenades, as long as the high-level zombies are not close to the Beishan base, Lin Feng will have enough time to prepare.

"Manager Qian, you and Elder Sima organized the ordinary people in the base to retreat from the north gate, and all the remaining base guards and cultivators stayed, and when the people all withdrew, the rest of the people could wait for the order to retreat."

Chief Qian and Elder Sima were ordered to quickly go to the shelter on the northwest side to organize the evacuation of all ordinary people, Lin Feng could still think of the people at a critical moment, Chief Qian and Elder Sima were very pleased, because they felt that Lin Feng could treat ordinary people like this, wouldn't it be better to treat the disciples of Xinmen.

In this regard, Lin Feng is very embarrassed on the city wall, heavy weapons can only block the advance speed of high-level zombies, but like destroying zombies, more powerful weapons are needed, although the concentrated nuclear magnetic resonance rocket launcher can destroy third-level zombies, but the distance is a hard injury, and the cooldown time of the bazooka is also fatal, once it is not mastered well, it will give zombies a chance.

Excluding the problem of zombies, the Iron Tree Country actually wants to launch antimatter weapons to attack here, although it is said that it is good to prevent the dead cycle, but the Iron Tree Country actually wants to attack the base of the Shenhua Kingdom, it stands to reason that although the Iron Tree Country is strong, it is too wide.

If the Iron Tree Kingdom really launches the antimatter weapon, not to mention the Beishan base, the entire Tianheng Mountain Range will disappear with it.

The zombie group in front of him has not been solved, on the other hand, they have to consider how to deal with the attack of the Iron Tree Country, if the other party really has a dark matter weapon, with the speed of the people, can they escape?

The zombies in the distance are getting closer and closer, the role of the heavy laser cannon is gradually decreasing, and more and more high-level zombies appear on the dividing line, and in the end, Lin Feng not only felt the existence of the sixth-level mutant zombies, he also felt that in the distance, a familiar energy, very huge, was coming here little by little.

"What is it, so familiar? It is the energy of the ancient underground civilization, there are those red-clothed people underground, and there are also underground city ruins that record the magic wolf exercises, what is this energy? Could it be that someone from the underground city has come out? How many people will come out together to have such tremendous energy. ”

Lin Feng used the Demon Wolf Technique to feel the energy fluctuations in the distance, there was only one sixth-level mutant zombie, although it was a terrifying existence for ordinary cultivators, but for Lin Feng, it was still possible to fight, but the huge energy that followed closely behind, what was it?

"Report to the Leader, the Flying Machine has spotted a huge monster coming towards here, looking like a giant mutated octopus, but the size of a small hill."

Lin Feng was still puzzled, one of his subordinates had already reported the news ahead, and the huge organism seen by the flying machine was supposed to be the source of the most powerful energy.

"Could it be the thing that Elder Sima said? The thing that comes out when there's a big war? ”

Lin Feng suddenly remembered what Elder Sima had said, as long as there is a large-scale war, there will be a monster that will be attracted, as for what this monster did, no one knows, because all the places where this monster went were razed to the ground, and there were no living creatures left, even zombies could not escape.

And now, what Lin Feng has to face will be a three-sided threat, can Lin Feng alone retreat?

With a long roar, the roar of the sixth-level mutant zombie had already arrived. (To be continued.) )
