"Use the turret to attract the attention of the stalker, prepare the bomb, flame thrower and laser transmitter, and have a barbecue intestines!" Du Xingyu commanded.
The soldiers immediately began to arrange and use the fort as bait according to the underground route of the stalker.
When the shell was ready to launch and produced a high thermal reaction, sure enough, the concrete ground was broken and the stalker began to collide with the turret.
"There it is! Fire!" countless machine guns, shells, lasers and flame throwers aimed at the stalker.
There is also a layer of mucus protective film on the surface of the stalker''s body, but the hot flame immediately roasts and evaporates the protective mucus, and the laser and bomb completely destroy the part of its body exposed to the ground. But its underground part, like an earthworm, still has vitality and hides underground.
"The operation was successful. Although it was not killed, the stalker should have no combat effectiveness for at least a few hours!" Du Xingyu said.
In the sky, the acoustic pterosaur besieged by laser was also hit several times and was always unable to enter the interior of Yunzhou base.
"The second layer of defense can''t hold!" the front commander of the second layer of defense urgently shouted to the command center, "there are too many variants!"
Li Tai looked at the time and insisted for another 20 minutes.
"Withdraw to the city!"
The third layer of defense is the defense system outside the fortress city. It is the last line of defense for 40 million people!
Outside Yunzhou fortress city, there is a high concrete wall with various defense weapons installed on it. This was established after the biological catastrophe. It has blocked the invasion of mutant organisms many times.
Standing on the wall dozens of meters high, you can see the distant mutant creatures rushing towards the Yunzhou base!
They are fearless of guns, ferocious and cruel. Even the most powerful special soldiers will shudder in the dark, all kinds of breathtaking roars and bloody hell scenes!
What''s more terrible is that more grade 4 and grade 5 variants are emerging! The animal tide is at least three times higher than human expected!
"Yunzhou base, can you hold it?"
"Yunzhou base, it''s over!" all over the world, the surviving humans in all major regions are paying attention to it. When they saw the variant rush to the third line of defense, they all had a kind of despair of rabbit death and fox sorrow.
China has been the most successful against biological cataclysm. If they can''t resist the attack of animal tide on land, what about the super monsters bred in the sea?
"Human beings, there is no hope!" countless people sigh at the bottom of their hearts.
The fighting continued. At every moment, variants were killed, but also the soldiers of the base fell.
"Ask for support, the city wall can''t hold! There are two more sneakers, which have damaged the city ground!"
"The automatic defense system has been destroyed! Sonic pterosaurs began to attack the city!"
"There is a gap in the south, and a large number of variants rushed into the city!"
While these variants entered the city and wantonly destroyed human buildings, they began to look for people''s hiding places.
They have a variety of abilities to perceive the outside world, can quickly find attack targets, and some variants have even begun to attack the biochemical protection center.
"Help! Help us!" tens of thousands of people wailed in horror in a biochemical protection center.
Outside them, there were constant sounds of destruction and explosions.
The soldiers of the shelter have fought against the invading variants, and their heat weapons are like children''s toys in front of the advanced variants!
"Are we going to die?"
"It must hurt to be eaten by a mutant monster!"
"Why, why?"
"Doesn''t it mean there are secret weapons? Or can''t resist those monsters?" panic spread in the crowd. Who doesn''t know how long their lives can last!
"Boom!" with a loud noise, a skull armor giant elephant hit the shell of the shelter, making a violent noise!
"Don''t worry, it won''t open!" the staff was comforting the masses. An acid bomb was thrown on the wall of the shelter.
A large piece of thick reinforced concrete was corroded immediately, and the bone armor giant elephant was once again weak. The wall could no longer resist, and a large area collapsed directly. The mutants smelled the smell of human beings and rushed frantically here!
"It''s over! It''s all over!" everyone was pale. Several soldiers frantically attacked with lasers and flame throwers, but they couldn''t stop their progress.
A giant elephant with a skull armour has entered the Protection Center under gunfire!
It roared at the sky, as if to trample all these humans into meat and mud!
It began to charge, with unstoppable power! Fifty meters, thirty meters, ten meters! The giant elephant in bone armor is approaching the crowd. People can''t hide!
Some are crying, some are desperate to close their eyes and wait to die, others want to escape or resist! But all this seems futile!
"Dong!" with a dull loud noise, the ground shook violently once!
This shock is not caused by the running of the bone armor giant elephant, but another mutant creature!
It fell from the sky, with a body more than eight meters high in front of the crowd. His body was covered with long hair, his legs were upright, and he was carrying rockets and bombs.
On its hair, a "T-35" logo is written with fluorescent markers.
This is a level Four variant, iron tyrant!
It fell from the sky, smashed the head of the bone armor giant elephant with a fist, and the red blood and white brain collapsed everywhere!
"It''s mutant animals. They''re fighting?" people were terrified.
"No, this mutant beast seems different from the one outside!"
"Yes, it didn''t attack us. It seems to be helping us. What''s going on?" people were stunned.
They saw that the iron tyrant equipped with modern weapons blocked the hole, and all the variants trying to rush in were hammered or torn alive by it!
"It''s our secret weapon!" a soldier looked at the sky in surprise. A group of transport planes were flying over the sky. They were constantly dropping biological and chemical weapons.
There are iron tyrants, double headed blood cattle and mountain piercing Jialong. The heavier bone armor giant elephants are not put in by transport aircraft, but transported outside the city by train.
These modified biochemical weapons, controlled by the biochemical brain, began to attack the beast tide!
"Hiss!" as soon as a pangolin fell to the ground, it got into the hole drilled by the diver and began to bite the diver.
As a tertiary variant, it is not an opponent of stalkers at all. But it has helpers, and more mountain piercing beetles gather together to attack the stalkers.
Many ants can still kill elephants. These powerful three-level variants can also make the five-level variants unbearable!
Soon, a stalker was dismembered alive under the ground!
On the ground, the two headed blood cattle are colliding. The bones of the secondary variants are broken by it. Even the tertiary variants can''t stop its collision.
Outside the city, a group of artificially cloned bone armor colossus rushed back, and the animal tide became chaotic.
The level 5 mutants flew into a rage and began to attack these "traitors"!
But they also have their own opponents, that is, the reformed iron tyrant!
Although the iron tyrant is a level 4 variant, it has stronger physical strength after human strengthening. And it is more flexible. Two iron tyrants rush up together and can tear up a battlefield shooter in 15 minutes!
There are even iron tyrants who climb up a hundred story building, fly to sonic pterosaurs with strong bouncing power and tear their wings alive!
"Finally! Our secret weapon!" Du Xingyu was able to put his heart down when he saw the biochemical weapons put into the battlefield.
"This is a biological weapon? It''s too strong!" all the commanders in the headquarters looked silly!
The mutants they worked hard to defend with their lives were slaughtered like chickens in front of man-made biochemical weapons!
Especially the strengthened iron tyrant, under the control of biochemical brain, can move more quickly and attack with weapons!
They are like tigers into sheep, killing everywhere!
"How many of these iron tyrants?" asked a commander.
"There are 300 without modification!" said Du Xingyu. "After strengthening, there are more than 200, a total of 500!"
"Five hundred level four variants!" everyone was startled, followed by irrecoverable ecstasy!
"The driver variants of this animal tide are estimated to be only more than 300, and 500 iron tyrants can tear them all up!"
"Yes, and they can attack level 5 variants with the advantage of quantity!"
"Great! We''re saved!"
"Yunzhou base can hold!" Li Tai said with great joy.
"Not just hold on!" Du Xingyu gritted his teeth. "These variants have hurt so many of us. This time, we will wipe them out!"
"In addition to 500 iron tyrants, the biochemical Arsenal cloned 1000 double headed blood cattle, 500 bone armour Colossus, 1000 pangolins, and 5000 predators!"
"The first big battle between humans and mutant beasts must win!"
Du Xingyu''s biological computer has been connected to the computer of the headquarters. At the same time, he can see the pictures of these biochemical weapons and command them.
With man-made biological and chemical weapons on the battlefield, defense is no longer a problem.
Du Xingyu''s goal is those level 5 variants. As long as they are defeated, this animal tide can definitely win!
"Another battlefield shooter!" Du Xingyu commanded a biochemical team to rush up.
Predators are agile and probe for intelligence. The bone armor colossus has amazing defense and acts as a tank in front to attract hatred, while the double headed blood cow is responsible for breaking through the defense by collision and sharp horns.
Chuanshan Jialong dialysis underground, three iron tyrants as the main C, crazy output!
The level-5 variant that the garrison had been defeated one after another just now turned into a pool of rotten meat within three minutes under the attack of the biochemical team!
"Three minutes and 12 seconds, the speed can be faster!" Du Xingyu continued to control biochemical weapons and look for the next target!
