Li Tai connected the communication, and Du Xingyu appeared on the display screen.


    "Hello, Professor Du," Li Tai said.


    "Hello, commander Li," said Du Xingyu. "I''m contacting you this time because we have made progress in biological and chemical weapons."


    "Do you have any new weapons?" asked a group of commanders.


    "Yes," said Du Xingyu, "the first batch has been sent to Yunzhou base, and I''m on my way. What''s specific? Wait until you come."


    On the railway to Yunzhou, a train runs at high speed and is escorted by combat effectiveness.


    On the train, there are huge opaque glass containers, which seem to be soaked with something.


    Du Xingyu was sitting in the middle carriage of the train with a group of biochemical weapons and military experts.


    "Whether we can succeed this time depends on this!" Du Xingyu put the secret weapon of this trip in his suitcase.


    Biochemical brain is a biological computer specially developed for mutant monsters. Using it can replace the brain function of mutant organisms and control the corresponding mutant organisms.


    This kind of chip is also graded. The rear manufacturing factory can mass produce secondary biochemical brain, and the output of tertiary biochemical brain that can control tertiary variant organisms is less.


    After the era of biological cataclysm, some major transportation trunk lines were guarded by heavy troops to prevent the transportation lines from being cut off.


    Along the way, some scattered mutant creatures attacked the train, which were found and killed in advance by the escorting fighter.


    Du Xingyu came to Yunzhou base, where a group of military commanders had been waiting for him for a long time.


    "Professor Du, I''m looking forward to you at last!" Li Tai, as the Supreme Commander here, came to meet you personally.


    "Professor Du, if you don''t come again, we don''t know what weapons to use!"


    "Yes, those mutated creatures have evolved too fast. Now there are many mutated species that are not afraid of heat weapons. There is a giant elephant with bone armor. Our shells can''t break through its exoskeleton. It can crush an armored vehicle with one foot!"


    Commanders complain one after another. They are stationed here. They don''t know how many tactics they have tried and how many soldiers they have lost, but they are still at a disadvantage!


    "Professor Du, what kind of weapon did you bring this time?" this is what they are most concerned about.


    Du Xingyu smiled and said, "please look!"


    Behind him, the cargo box of a military transport vehicle opened and a large glass container appeared on the train.


    "What is this? Chemical weapons?" the crowd said strangely.


    "Turn it on!" Du Xingyu gave an order. The biological computer in his body directly gave instructions to the electronic equipment of the container. The protective color of the glass container began to fade, and a predator soaked in nutrient solution appeared in it.


    "Secondary predator?" Li Tai certainly knows this creature. Although predators are not very powerful, they are very agile and numerous, which has brought them great trouble.


    In the glass container, the predator suddenly opens his eyes, the glass container opens, and the predator pops out of his head.


    "Professor Du, be careful!" several commanders and guards immediately raised their guns nervously to attack the predators.


    Du Xingyu waved his hand and said, "don''t get excited. The weapon I''m talking about is its biochemical brain. This predator''s brain has been completely replaced by a biological computer. Now it''s under my control."


    "What?" a kind of soldier was shocked when he heard his words.


    In their eyes, these mutant creatures are cannibal enemies. They have no humanity. How can they be controlled by people?


    "Biochemical brain? Can you really control these mutant creatures?" one man wondered.


    "Get down!" Du Xingyu shouted.


    Behind him, the grinning predator lay down and did not move.


    "Jump in place!" Du Xingyu ordered again.


    The predator jumped up fiercely, ten meters high! Then it fell in place again, without any superfluous action, like a machine without emotion!


    "It really listens to the instructions!" Li Tai was surprised at first, then said with joy. "If we can control the mutant creatures, the whole war situation will be reversed! These mutant creatures are ten times stronger than heat weapons in special places!"


    "Professor Du, you are really our Savior!" a commander quickly asked, "how many predators do we have?"


    Du Xingyu said: "this time I brought 1000 predators, all implanted with biochemical brains. They can accept our electronic signal instructions and turn on the intelligent mode."


    "These predators are the first experimental products. They are mainly used for intelligence reconnaissance."


    "If it goes well, I will make stronger biological and chemical weapons!"


    "Good! Ha ha, good!" Li Tai said with a smile, "we are worried about not knowing the details of Yunzhou insect nest!"


    Du Xingyu said: "this time I also brought a research team and a temporary research base. Yunzhou insect nest will be my biological and chemical weapon test site and the first battlefield for us to fight back!"


    "Professor Du, don''t worry. As long as there is one soldier left in Yunzhou, we will protect your safety! So that you can carry out research and experiment smoothly!" Li Tai saluted.


    Du Xingyu saluted back. He and his team stationed in Yunzhou base and began practical research.


    After the first 1000 predators were set with intelligent programs, they were all put into the area of Yunzhou insect nest, the human restricted area after the catastrophe!


    The eyes and nose of these predators will transmit the detected information back through the signal transmission device of the biological computer.


    When humans retreated, some signal devices were arranged in Yunzhou area, so they can receive these information smoothly.


    "In three days, we have gone deep into the insect nest in Yunzhou. These predators are so easy to use!" Li Tai looked at the electronic screen in surprise at the headquarters of Yunzhou base.


    They are also implanted with biological computers, which can directly receive information through biological computers, but Du Xingyu found that some mutant creatures can transmit brain wave information similar to "hypnosis", so when receiving predator information, they will not directly receive it with their own biological computers to avoid being attacked by biological signals.


    In the picture from the predators, they have entered the depths of the mountains. Here, they can rarely find familiar animals and plants.


    Even seemingly harmless trees may open their mouths and predators one by one!


    A thousand predators lost more than 200 in three days.


    "According to the detection information in recent days, the periphery has almost been covered with secondary variants!" Du Xingyu said, "and this is less than 10 percent deep!"


    "It seems that my research on ''insect nest'' needs to be updated. In the insect nest, the speed of biological evolution will be accelerated!"


    "Professor Du," said a military expert, "this is the distribution map I just calculated."


    He sent the chart calculated by the biological computer to the display screen, which divided the sub areas of the variants with different colors. The darker the color, the more variant organisms and the higher the level.


    "From the information we had before and the information detected by predators now, it shows that mutant organisms have transferred to Yunzhou base on a large scale."


    "To be sure, the next animal tide attack is not far away!" Li Tai said seriously.


    Du Xingyu carefully observed the chart. He frowned and said, "how do I feel that the movement of animal tide is too purposeful and regular. Logically, they should not know the location of Yunzhou base, but their movement purpose is so accurate. Is there a creature directing?"


    "Professor Du, we also doubt this!" a commander said immediately. "It''s too strange. It''s reasonable that these creatures are natural to plunder resources, just like locusts. But these mutant beasts obviously want to attack our human cities and bases. Do they also have commanders?"


    "Great probability." Du Xingyu nodded. "According to our research on mutant organisms, class I, class II and class III mutant organisms do not show the wisdom of advanced intelligent organisms. However, once the infection degree of Z virus reaches more than 40%, they should have primary wisdom. If they are class IV and class V mutant organisms, they may have human wisdom."


    "It''s terrible that such a terrible monster still has human wisdom!" Li Tai worried.


    "Unfortunately, I have never had living research materials for level 4 and level 5 mutant organisms." Du Xingyu regretted, "one of the purposes of my coming to Yunzhou base this time is to obtain advanced mutant living research materials."


    "If you need anything, just tell us, and we will cooperate fully." Li Tai has realized that Du Xingyu''s research will determine the direction of the war!


    The predators continued to go deep into the insect nest in Yunzhou. Another week later, there were less than 200 predator intelligence soldiers left.


    Du Xingyu has more and more information about Yunzhou insect nests. He knows more variant information and the sub regions of variant organisms.


    According to the division, they roughly drew a distribution map of Yunzhou insect nests.


    "There is a layer of secondary mutant animals and secondary mutant plants on the periphery of Yunzhou insect nest, which constitute the external defense system of the insect nest. We have never broken through this defense!" Li Tai said.


    "Then there is the middle-level area, where there are frequent activities of level 3 mutant creatures and a small number of level 4 mutant creatures. It is worth noting that these level 4 mutant creatures seem to have their own territory, just like mutant animal generals!"


    "In the core area, predators can''t go deep at all."


    "There must be five level variants in the core area, and its combat effectiveness is comparable to that of the nuclear strike force!" Du Xingyu directly concluded. "The distribution of insect nests makes me sure that it must have a commander with high wisdom!"


    "What I''m worried about now is that there is a level 6 variant in the Yunzhou insect nest, that is, the boss of the planetary warship level!"


    When it comes to the planetary class, everyone here feels afraid for a while. They know that the aircraft carrier in North America was sunk by the class 5 variant. So the level 6 variant can easily destroy the whole Yunzhou base?
