The hordes of zombies were like a slowly rolling black viscous tide, surging in the direction of the survivor base, slowly, but unstoppable, almost without the courage to stop it.

"I'm in trouble." Xingyu watched from the side, his face was not very good-looking, "I hope I think wrong." ”

"What's wrong?" He Li turned his head and asked.

Although it is a zombie tide, it still doesn't seem to be much of a threat for the time being, even if they are really besieged, they can also use biochemical grenades to break through, like those ordinary zombies do not have the slightest resistance in the face of biochemical grenades, it is completely swept away, and only mutated zombies can resist one or two.

There shouldn't be anything to worry about, right? He Li thought, if it really doesn't work, they can definitely escape, although this approach is a bit selfish, but at that time, He Li can't care so much, at most bring Beihuan again. As for the lives and deaths of others? What does it have to do with her?

He Li is not an amorous saintess, she is even very ruthless.

"I'm not worried about dangerous things." Xingyu always seemed to be able to see what He was thinking, and he said, "Sister, have you noticed that there are only ordinary zombies in the zombie group, not even a single enhanced zombie, not to mention the existence of mutant zombies and mutated biochemical creatures." ”

There is a simple division of zombies in the survivor base, ordinary zombies, enhanced zombies, and mutated zombies. Ordinary zombies refer to the largest number of zombies and the weakest zombies, they move slowly, their bodies are rotten and fragile, even if it is a fifteen or sixteen-year-old boy, as long as he has courage and is calm enough, he can defeat many ordinary zombies. Strengthened zombies refer to slightly mutated zombies, their bodies stop decomposing and will grow bloody flesh, generally relatively intact, and also very tall, usually several meters tall, can easily knock down a large area of ordinary zombies, and the strength is about the same as that of human first-level evolutionaries. As for the mutant zombies, it is a general term for those more powerful zombies, and their strength is equivalent to that of an evolutionary person above the second level.

He Li looked towards the group of zombies, and the dense zombies looked numbing. She carefully searched for the abnormalities in the zombie group, and the tall strengthened zombies and mutated zombies of different shapes should be easier to find. But He Li didn't find anything unusual, there were only almost endless ordinary zombies in the zombie tide, their bodies were rotting and damaged, and they were slow to move.

That's really not right. You know, the mutation efficiency of the virus is very high. Under normal circumstances, there is a chance that one enhanced zombie will appear in hundreds of zombies. And at this moment, there is not a single enhanced zombie in the zombie group, let alone a mutated zombie.

"How so?" He Li thought of a very terrifying possibility.

If it is really a wise zombie that is controlling the zombie group, this situation indicates that the intelligent zombie will gather the enhanced zombie for other attack preparations, which also shows that the wisdom level of that intelligent zombie is not so low, so it is even more difficult to deal with it.

"There is another possibility," Xingyu said in He Li's ear, "That intelligent zombie itself is not powerful, and it can't manipulate stronger zombies, so only ordinary zombies appear." ”

"Of course, this is not very likely, I don't think it is possible that the intelligent zombies who can control such a large group of zombies will not have the ability to control some enhanced zombies." Xingyu's next sentence extinguished the glimmer of hope that He Li had just risen.

He Li knocked on Xingyu hard, don't give me unhurried next time I speak!

Just made such a small fuss, and the atmosphere suddenly relaxed a lot.

"That's right." Bei Huan took out a few crystal-like things and handed them to a few people, "The base issued it, it is said that it is very convenient to deal with zombies, but there are few of them, keep them for life!" Three per person, just press the button and throw it out. ”

"Huh?" He Li looked at the familiar thing in his hand and smiled dumbly, "Biochemical grenade?!" ”

What Bei Huan put in their hands was a biochemical grenade.

This thing...... I have hundreds of them here...... He Li's face twitched, but then he returned to normal, and together with Xingyu Chen Mo, he pretended to be casual and put away the biochemical grenade.

"Sure enough, there are also members of the 'God' here," Xingyu sneered lowly, "There are only three biochemical grenades per evolutionary?" Why are you still so stingy? ”

His gaze fell on Bei Huan's waist bag, her waist bag was very small, and she couldn't fit many biochemical grenades, and she was wearing a tight combat suit, and she didn't have much to hide in. It is unlikely that Beihuan is greedy for ink.

"Get into range and fire!"

Suddenly, the radio in the base rang out, a heavy and powerful voice.

Suddenly, the artillery that had been prepared on the wall of the base for a long time spewed out tongues of smoke and fire at the same time.

The cannonballs exploded violently in the zombie tide, stumps and broken arms and rancid flesh flew with a fishy smell, and hundreds of zombies were taken away in just one wave of shelling, but this is only a drop in the bucket for the desperately terrifying numbers of the zombie tide.

"Keep shelling!" He was not far from the commander, who was not far from the discovery, using the radio to issue battle orders.

"It's okay now, when the zombies rush through the artillery coverage area, the gunfire coverage area and the barbed wire fence used to obstruct it, it is estimated that the battle will really begin, and it will be time for us to start casualties." Bei Huan said, his eyes fell on the zombie group not far away, "This number, it is estimated that the base does not even dare to send out infantry vehicles or tanks and the like, and being surrounded by zombies is a loss of one, and it may not outweigh the loss." ”

He Li nodded slightly, she also knew that the base was also heartbroken, these artillery pieces and the heavy equipment owned by the base, in the eyes of the base, almost every one of them could be compared with thousands of people, and it was estimated that the base would not be taken out casually.

Although the power of the artillery fire is large, the rate of fire is slow, and it cannot stop the advance of the zombies who have followed one after another, at this time, the zombies have come to the trap area that has been carefully arranged and prepared, and under the cover of fire, they are blocked by barbed wire, and the zombies stopped by the trap trench have begun to fall in large areas.

But there were so many zombies that they quickly filled all the traps with flesh and blood.

Ahead is the area covered by gun fire, which is the last line of long-range defense, and the battle is about to begin!

Soldiers with full protective measures shoot wildly at the zombies on the wall.

The wall is their last guarantee, if the zombies break through, it will be the last hand-to-hand combat, and at that time, it is estimated that it is time to prepare to flee for their lives!

He Li also put on the protective clothing specially made by the base to wrap around the whole body, and came to the wall to watch the battle, at this time, there was no need for them to interfere for the time being.
