"According to the migration speed of mutant animals, they can form a threat to Yunzhou base in at least 60 days!" Li Tai said. "What should we do in case of the attack of advanced variants in the insect nest?"


    "If it has wisdom, it should not rush out." Du Xingyu analyzed, "it should be very clear that mankind has nuclear weapons. Although we will not use them easily, we will also use nuclear weapons if we have to."


    "Even level 5 and level 6 variants will be afraid of nuclear weapon attacks. Therefore, its best strategy is to command low-level variants to attack Yunzhou base and test our cards and strength. Use variants that can be manufactured in batch to consume our armaments!"


    "But even so, it seems that we can''t resist the animal tide!" said a military expert reluctantly.


    "Predators are not aggressive in the front battlefield. We need stronger biological and chemical weapons to win!" Du Xingyu said. "Before the animal tide comes, we must take several raids."


    "Raid?" the crowd looked at him.


    Li Tai wondered, "we don''t know that those mutant creatures can command low-level variants. It''s also difficult to break through the defense line outside the insect nest!"


    Du Xingyu shook his head and said, "there is no need to attack the commander. I mean, using the information detected by the predator biochemical scout, use strange soldiers to enter the central area of Yunzhou insect nest. Capture the level 3 or even level 4 variant and bring it back."


    "Then give it to me for research and implant biochemical brain control. If we can replicate it in large quantities, we will also have advanced biochemical weapons!"


    "Well, at present, this is also a more feasible tactic!" the commanders agreed.


    They began to choose to capture targets. On the predator exploration route, there were some territories of level 3 and level 4 variants.


    "The first is the third level variant, and there are three optional targets." Nie Xinling, a biochemical military expert, marked the target.


    "They are three-level variants, double headed blood cattle, which are derived from a gene mutation of bison. They have two heads, four horns, blood red all over, omnivores, rough skin and thick meat, and amazing impact power."


    "The giant elephant in bone armor, a variant of the Asian elephant, is covered with a thick layer of exoskeleton, which can resist the bombing of ordinary shells. It is huge and can easily destroy military defense facilities!"


    "Pangolin beetle, a suspected pangolin variant. It is bigger than the Komodo lizard before the disaster. It can move in rocks and underground, which is a strong threat to underground facilities!"


    These three goals are variants of proven territory and strength.


    Du Xingyu nodded: "you can choose. But you can''t just rely on the third level variant. You have to capture the fourth level variant."


    "There are few grade IV variants, and each one has high difficulty and risk to capture." Nie Xinling analyzed, "we only have two optional targets, and we probably only have the chance to capture one."


    "Yunzhou python, a level 4 variant, is more than 50 meters long and can spray acid to corrode machinery and equipment. It once destroyed one of our temporary garrisons!"


    "Iron blood tyrant, a level 4 variant, is derived from bears. He is five to eight meters tall and agile. His running speed, jumping ability and defense ability are amazing. His power can throw 16 ton armored transport vehicles out. On the front battlefield, it is more threatening than Yunzhou Python!"


    Du Xingyu carefully observed the existing data and said: "no matter how you look at it, the difficulty of catching the iron blood tyrant is lower than that of Yunzhou crazy python. The iron blood tyrant is very irritable. As long as you provoke it, it will not die. Once seriously injured, the crazy Python will escape the scene. It is difficult for us to catch it in the insect nest."


    "Capture the iron tyrant..." Li Tai thought and said, "we can only send special operations teams to go deep into the insect nest. Weapons of mass destruction are inconvenient to enter. If we want to catch alive, we must make it lose its action ability."


    "I''m afraid it''s a little difficult to accomplish this by relying on rockets and fighters."


    "Use Z virus inhibitor!" said Du Xingyu. "Z virus inhibitor will cause a certain degree of confusion for variant Z virus. Although it is not enough to kill them, it can make them fall into a coma in a short time."


    "Before departure, I will prepare special injection bombs for special operations forces!"


    "OK, that''s it!" Li Tai made a quick decision and said, "Three Level 3 variants and a level 4 iron tyrant must be captured in the shortest time!"


    They immediately began to formulate tactics. Relying on the information explored by predators, they could roughly find hidden routes and go deep into the middle of the insect nest.


    Special forces and special injection bombs to capture Level 3 variants should not be a problem.


    The most difficult thing is to capture the iron tyrant. The level 4 variant has tenacious vitality, and the injection bomb can''t take effect immediately. In addition, these four level variants are under the command of senior intelligent creatures in the insect nest. Once in danger, there will be other variants to support.


    Therefore, while implementing the capture plan, they also need to send an artillery team to attack the insect nest somewhere, attract the attention of those high-level variants and create conditions for special operations forces.


    The position of the variant can change at any time, so special operations began that night. Four special operations teams rode predators, took equipment and sneaked into Yunzhou insect nest.


    Artillery and air support units are also ready and ready to go!


    "The first special operations team has reached the target area!" only in the past five hours, the first special operations team has reached the target area.


    During this period, they also encountered some low-level variants, which were easily killed by them. The lethality of gun attack on primary and secondary variants is enough.


    On the monitoring screen, the team has entered the activity area of double headed blood cattle.


    Cattle were originally social animals, but after the mutation, double headed blood cattle became omnivores, which could absorb meat and plants, so these aggressive double headed blood cattle also began to become solitary predators.


    In their drone shooting, a two headed blood cow is sleeping in a mud pit.


    "Sniper aim!" the snipers aimed at several main parts of the double headed blood cow. The special sniper gun contained a special injection bomb with Z virus inhibitor.


    "Three, two, one, shoot!" with the captain''s order, six snipers gathered two headed blood cattle at the same time.


    "Hiss!" the two headed blood cow shouted angrily. These special injection bullets can''t make it fall into sleep for a while and a half.


    It began to run wildly, looking for the enemy.


    The team members are calm observers. When dealing with a single variant, the human force is still very powerful. What they fear most is that the variant will form a wave of animals and impact the human city.


    Several predators transformed by biochemistry rushed out, attracted the hatred of two headed blood cattle with their agile speed, and made it run angrily and waste its strength in vain.


    More than ten minutes later, the inhibitor began to take effect. The double headed blood cow fell heavily to the ground. The team members immediately went up to tie it up and continued to inject the inhibitor to make it unconscious.


    "Report, team Yifan has completed the task," team Yifan replied.


    "A shield in the distance, waiting for the support of the transport plane!" Li Tai ordered.


    "Yes!"


    It''s also troublesome to transport these variants. They have to wait for a unified opportunity, and there will be transport planes to help transport them.


    At the same time, the second and third teams have begun to capture tasks.


    "Report to the headquarters. This is the second team. The Oracle colossus has been captured!"


    "Report to the headquarters. This is the Sanfan team. The mountain piercing Jialong has been captured. Two team members are injured. Request support!"


    "Emergency treatment, our support will take another hour!" Li Tai ordered.


    "Yes!"


    The three head and three level variants have been captured, leaving only the iron tyrant of the four level variants of the four team!


    There are twelve members in the sifan team. They have come to the proved area where the iron tyrant is active.


    This is a valley with dense vegetation, in which there are many mutated plants and some poisonous insects, which will be injured accidentally.


    Fortunately, predators opened the way ahead, and they were safe all the way.


    "Found it!" Gao Xing, the captain of the sifan team, found the iron tyrant through the predators.


    The predator dived into a cave full of broken rocks, which was obviously dug by the iron tyrant himself. As soon as the predator entered, a black monster rushed out and slapped it to death! Then he bit off his head and dragged his body back to the cave for a big meal.


    "It''s hiding in the hole, we can''t get in!" a team member whispered.


    "Use smoke bombs and tear gas to drive it out," Gao Xing said. They had done their homework before they came.


    "Set up traps in advance! For such a big guy, the inhibitor works too slowly. Give it two shots first!" the team members began to look for high points, arrange snipers and assemble mortars.


    At the same time, Li Tai began to command Artillery Forces to bomb insect nests, attracting the attention of intelligent creatures and advanced variants in insect nests.


    "Coordinate the central area of the insect nest, start bombing!"


    "Fire!" from Yunzhou base, long-range missiles bombed the central area of the insect nest under the guidance of satellite signals.


    With the first shell landing, the insect nest immediately issued an earth shaking roar, a large number of mutant birds flew out and began to intercept missiles!


    There are also huge mutant plants that stretch out vines that can move flexibly to hit shells. Unknown creatures spray acid into the sky. The hit rate is like loading a precision guidance system. Most missiles are intercepted in the air.


    "What a terror! The cooperation and attack of these creatures are stronger than a modern army!" Li Tai sighed when he saw this scene.


    "It seems that the core of the insect nest is not only as simple as the advanced intelligence. They also have a complete division of labor and different arms." Du Xingyu analyzed, "what makes me most curious is their biological weapons!"


    Acid, flame, bioelectricity, and plant airbag bombs. Du Xingyu wants to get their gene samples. Maybe he can integrate these biological weapons into biochemical animals!
