Experts are still discussing options, but the teams in the safe zone who are attacked by giant zombie bugs on the ground are in a precarious situation.

At this time, the commander-in-chief decisively gave the order.

"Which team is near the Hongcheng City Security Zone team, hurry up and support them!

Now the situation has changed, and several adjacent safe zone teams can come together to fight, and the overall formation still needs to be maintained! ”

After the commander-in-chief gave these instructions, he picked up another walkie-talkie, and hesitated for a moment before speaking:

"Fly one group, two groups, drop incendiary bombs in the air, choose the area with the highest concentration of zombie insects, control the number of incendiary bombs used, and be sure to achieve the most ideal effect with the minimum consumption!"

"Yes! Sir! ”

Two more helicopters were immediately raised on the ground, and after slowly rising into the air, they flew further forward in the safety zone.

More bugs can be seen gathering in this direction from the air.

"A set of incendiary bombs is ready to be dropped!

Put!!! ”

"Two sets of incendiary bombs are ready to be dropped!

Put!!! ”

After a while, there was a fire in front of the sky, and the incendiary bomb burned among the zombie insects, just like the flame ignited a large amount of gasoline, the characteristics of the zombie insects, so that as long as they were contaminated with an open flame, they would burn, and the density of zombie insects made it so that when a zombie insect burned, it would ignite other zombie insects around it.

"The first round of incendiary bombs has been dropped, and a group is on standby!"

"The first round of incendiary bombs has been dropped, and the second group is on standby!"

"Report to the sir, find that the zombie bugs behind have stopped advancing, they are devouring each other, do you want to stop them from dropping incendiary bombs on them"

"Allowed to deliver!"

"Roger!

Preparation of the second round of incendiary bombs of the second group,

Put!!! ”

The incendiary bombs dropped by the helicopter from the air have a more precise and wide burning surface, which greatly helps the evolutionary team to reduce the number of ordinary zombie bugs, and can call on more attention to fight the giant zombie bugs.

Because of the elusive attacks of the giant zombie bugs, the teams in each security zone must come together to establish a common line of defense against counterattacks, mainly evolved people with strong perception.

This led to the destruction of the previously arranged formations, and now the safe zones in these places have become four teams when they come together.

Under the guidance of the commander, these four teams attracted the attention of the zombie insects all the way and slowly advanced in the direction of the wormhole.

On the other side, the evolutionary team and soldiers in the Kyoto Security Zone, which were at the heart of this battle, had already completed the arrangement of sonar jammers.

"The sonar has been arranged, whether to start it or not!"

"Start!"

With the commanding voice of the commander coming from the walkie-talkie, six sonar jammers were activated at the same time.

At the same time, in the darkness deep underground, six small green points of light suddenly lit up, and the huge and bloated insect mother writhed a few times uneasily, and her mouth made a mouse-like cry.

Obviously, this sonar did have an impact on it, but it didn't rush from the ground to the ground as experts predicted, on the one hand, because the mother worm was much higher than the ordinary zombie insect level, and on the other hand, because the hiding place of the mother worm was far from the ground, and the sonar interference had been significantly weakened when it interfered with this side.

Although the sonar jammer did not succeed in forcing the mother worm to the ground, it did succeed in provoking the mother worm, and after a mouse-like cry, something seemed to be rushing towards the ground underground.

After the soldiers turned on the sonar jammer, they left the position of the sonar jammer as soon as possible, and if the worm mother really appeared, where she would stay was undoubtedly a dangerous area of death.

The situation underground is invisible to everyone, but the zombie insects on the ground keep writhing after the sonar is turned on, and it seems that this kind of sonar makes them very painful, and even the giant zombie insects will be affected by some influences, and the speed of action has decreased significantly, even their sudden appearance from the ground can also give people enough reaction time to avoid their attacks.

The various security zones seized this opportunity and began to round up those giant zombie bugs

After about thirty seconds, a giant zombie insect with an even more exaggerated body covered with flesh thorns broke through the ground and appeared from under one of the sonar jammers, and its large mouth directly smashed the sonar jammer with its teeth.

This giant zombie insect is more than twice as thick as the average giant zombie insect, and its body exposed to the ground is five or six meters long, so you can imagine how terrifying its body is underground.

This giant zombie insect worm, the surface of the dark red body is covered with cyan flesh thorns, it looks like a mutated giant sea cucumber, and its three-circle spiral serrated mouth seems to be the common feature of these zombie insects, the difference is that this zombie insect like a sea cucumber has a pair of small eyes, and when it opens its huge mouth, the pair of small eyes are squeezed so that there is no trace.

Everyone immediately asked the same question in their hearts.

This is the mother worm?

It's really the appearance of this giant zombie, and it's really a bit powerful.

Fortunately, there is a locator in the body of the mother worm, so that people can determine whether the giant zombie worm in front of them is the body of the mother worm.

According to the radar, the location of the detector is still deep underground, so the one in front of you is just a more powerful giant zombie worm.

"This is not the worm mother, kill it immediately, Plan A fails, prepare to execute Plan B!"

The commander's voice sounded over the walkie-talkie, and everyone had a tangled expression of disappointment and shock on their faces after learning that the one in front of them was not the insect mother itself.

This giant zombie insect is not a worm mother, how huge is the body of the worm mother?

Immediately afterwards, seven or eight more of these giant zombie bugs appeared, destroying all those sonar jammers, as if they had received an order from the mother worm to come out and turn off the strange thing that made the mother worm uneasy.

After receiving the order to attack, several evolutionaries rushed over with flamethrowers, and when the scorching pillar of fire shot at the resting zombie insects, these zombie insects twisted their bodies very sensitively and quickly retracted the hole drilled out.

In the next second, those evolutionaries with flamethrowers were attacked by the giant zombie insects that suddenly came out of the ground, even if one of these evolutionaries with outstanding perception existed, they still couldn't react at the first time, and immediately two evolutionaries died on the spot because they couldn't dodge and were bitten by the giant zombie worm's jagged mouth.

Immediately, the teams in each security zone were also attacked by this more powerful and faster zombie bug, and the battle situation became tense again.

Not only that, Chen Fei's zombie radar also detected the appearance of second-level mutant zombies, thinking that it should be the same as before, these second-level mutant zombies are also puppet zombies controlled by zombie insects.

In this way, the strength of the worm mother also had a rough guess in Chen Fei's heart, in Chen Fei's opinion, the strength of this worm mother was at worst, and it was also a level of a third-level mutant zombie, and it might even be higher.

Now his position is more than 500 meters away from the ground of the wormhole, and it is impossible to detect the insect mother deep underground.

When the zombie radar detects the underground, the actual sensing distance will be greatly reduced, of course, Chen Fei will not think that this is a disadvantage of the zombie radar design, he will only think that this should be deliberately set by the system, which is equivalent to what kind of charging items, membership privileges and the like, if you want to turn it on, Chen Fei must increase the level of the system and increase the level of the zombie radar.

According to what the system says, there are many feasible functions unlocked by his zombie radar upgrade next time, the first is the terrain scanning function of the zombie radar.

At that time, when the zombie radar detects the fluctuations of the surrounding zombies, it will no longer be displayed in a flat manner, but a detailed map of all the projections of the surrounding terrain.

When the zombie radar detects the surrounding zombies, it will clearly be clear to the zombie divisions in every corner of each room, basically after the zombie radar is upgraded, it is equivalent to being within the effective detection range of the zombie radar, Chen Fei has 100% accurate control, and the safety factor is maximized.
