It is three kilometers away from the second line of defense of Yanhuang Dacheng.

This is a mountain, before the end of the world here was once an excellent artificial forest, once provided a lot of wood for the manufacturing industry in the nearby city, but unfortunately, after the end of the world, the nearby city became hell, and the woods here also became the ownerless forest, let them grow here, without human interference, and with the evolutionary factor, the woods here grew more and more luxuriant, without the help of some wind and flight abilities of the awakened, it was really not easy for the third team to get here.

At the same time, the continuous mountains became a natural barrier to the advance of the zombie army.

The task of the third brigade is to delay the progress of the zombie army, if the large zombie tide is allowed to advance according to the original route, it will not take long to reach the third line of defense, if the first mine defense line is used to kill the vanguard of the zombie tide, then the second line of defense is used to hinder the advance of the zombie army.

In addition to the mountains, the second line of defense is also natural and man-made barriers that can hinder the progress of the road, such as ruined cities, such as large lakes, etc.

Every time they arrive at a human city, whether it is a ruin or a complete city, zombies will naturally stop and walk around, after all, humans have lived in the town for too long, even if the end comes, the town becomes hell, it still does not reduce the breath left by humans here.

There are also large lakes, some of which were excavated by Yanhuang Dacheng when building three lines of defense, and some were naturally formed, although it is a very wasteful behavior to use the strategic material of water to block the zombie army, but it is not that Luo Yang does not want to, but there is really no way, the end of the earth has evolved, and even some microorganisms living in the water have mutated, not to mention that there is no shortage of some animals, mutant beasts, zombies, and human corpses, and the virus concentration has been very serious. What's more, the current filtration system in Yanhuang Dacheng has no way to completely purify these exposed water resources.

So most of the bases now use groundwater.

Some zombies have special abilities, and there are not many zombies that can dive, but if they are placed in the entire zombie army, this number is very small, if the mutant army has 10,000 zombies, then there are only more than 100 zombies that can dive, and the puddle is another very effective blocking tool for humans.

In order to build the third line of defense, Yanhuang Dacheng did not spend less energy, resources and manpower in this, during the period of building the three major defense lines, half of the resources of the entire Yanhuang Dacheng were used to build tracks and ramparts, even so, but more than two-thirds of the tracks were train tracks before the forced demolition.

The third line of defense is a mobile track that is used to carry different mechanical weapons, attract zombie monsters, shoot at the same time, and form a train cannon defense line if necessary. But considering that the mechanical equipment in Yanhuang City is now unusable, and the third line of defense has also lost its effect, if it weren't for the black smoke crisis that has been experienced before, the third line of defense can be said to be the most powerful of the three lines of defense, as I said before, the first line is used to kill the vanguard of monsters, the second line is used to block the advance of monsters, and the third line is used to annihilate the remaining monsters and zombies.

Now that the zombies have not yet reached the second line of defense, the army stationed between the second and third lines of defense does not need to be transferred to the fortress of the third line of defense for the time being.

After all, an inch of land is an inch of hope.

Suddenly, at this moment, a black spot appeared on a distant mountain, and soon the black spot spread out into a pool, and in less than a minute, the mountain was completely black, and there was no shortage of other colors in it.

"It's coming!" Suspended above the woods, Chen Jiahao said secretly.

The first time to face a large corpse tide, every warrior's heart is excited, but also shocked, many people who have awakened not long ago are facing the corpse tide for the first time, before that, the description of the corpse tide in the military academy is, endless, suffocating, absolutely devastating, at that time many people felt that such a description was too exaggerated, just a large group of zombies, for them, the new humans who have awakened the ability, the zombie is just a moving target.

But this time, they saw this endless zombie with their own eyes, and many people were directly dumbfounded, they never thought that the large corpse tide that was still kilometers away had already brought them this powerful sense of oppression, and if they fought face to face, that sense of oppression was even more unimaginable.

"All parties pay attention, when the corpse tide enters the attack range, all squad leaders will execute according to the plan." Chen Jiahao said towards the walkie-talkie.

"There are so many zombies, how can you fight?" The adjutant Zheng Jun on the side looked confused.

The reason why Luo Yang organized Chen Jiahao into the three teams of 'Ability Troops' before the attack, and let him serve as the commander, has a very important factor is that at this moment, he has evolved to the level of the early stage of the B rank, and once the gravity ability is raised by one level, it is a rather terrible thing, which can directly crush the zombies in an area into meat sauce and mince.

You need to be strong enough to control your abilities.

The second is that Chen Jiahao is under the influence of Duan Fei, and his military management ability is very fast, and now he can be described as Duan Fei's right-hand brother, this kind of talent, Luo Yang will not miss it.

"Don't worry, I'll delay them!" Seeing the army of zombies in the distance approaching him step by step, Chen Jiahao wiped the sweat from his forehead and said.

It's impossible not to be nervous, and in the face of tens of thousands of times more enemies, no one will be afraid, but how to hide this fear in the depths of your heart, not show it and affect others, or turn it into some kind of power, this is the time to test people.

Roar!

At this moment, a tearing roar came from the direction of the zombie army, and the zombies who had been walking slowly and slowly rushed towards the woods like chicken blood after hearing this sound.

"The zombies attacked? Sure enough, there are commanding monsters inside! Chen Jiahao trembled, he didn't know if he would survive this battle, and no one knew if he could survive this huge group of zombies.

But in a person's life, there must be some times when he has to do something that he doesn't dare to do in his life, and what Chen Jiahao has to do now is to release his ability, and then.

Fight these zombies to the death!
