After simple sampling and analysis, Liu Tianxin determined that the toxic gas here contains a large number of microorganisms. On the one hand, these microorganisms will enter people with breathing, just like conventional bacteria and viruses. Invade the body''s immune system, the so-called toxicity.


    On the other hand, they will gnaw organic matter directly from the contact surface, which is corrosive to organisms. After testing, these microorganisms will also secrete acidic substances with strong corrosivity to metals. They also have a structure similar to multicellular and have relatively sharp mouthparts, which can destroy the oxide film on the metal surface.


    In addition, the fog will be absorbed by the soul force shield. It contains a large amount of soul force fog, which will be enriched on the surface of the soul force shield, which will make more and more microorganisms adhere to the surface. Greatly increase shield consumption.


    In other words, the vast majority of conventional ways, entering this toxic fog, will encounter considerable trouble.


    Fire and frost can indeed restrain the fog. The reason is also very simple. They can kill microorganisms in the fog. However, these fog are controlled by plant spirits and animals. They will attack the objects that release fire and frost with a certain initiative.


    "It''s a little troublesome, but it''s not a big problem! I think we can try to fight poison with poison. That doesn''t sound good. It should be called biological prevention and control." yak touched his chin, put the Petri dish containing microbial extract under the microscope again, looked in the car to find out all kinds of deeds and began to prepare.


    "You once said that you should defeat magic with magic." yak explained to the background living in his own spiritual sea: "in this difficult situation, it is often the simplest and efficient way to defeat the enemy with the power of others.


    The reagent I prepared can induce mutation to a certain extent. The focus is not mutation, but to change the recognition receptor of the first microbial protagonist. These microorganisms are too small to have too complex thinking, or even have no intelligent thinking at all. The method of identifying the same kind completely depends on the pheromones released by themselves and the receptors on the body surface.


    Next, I will cover our body surface and the surface of our vehicle with a layer of specific pheromone, so that these microorganisms that change the surface receptor will not attack us after we cultivate them. "


    "Wait a minute, they won''t attack us. Tell you that these microorganisms in the Petri dish, those in the fog, won''t recognize the pheromones in our car!" the photographer hasn''t responded for a while.


    "The reason is very simple. The microorganisms in my Petri dish will not recognize us as enemies, and the microorganisms in the poisonous gas will not regard the microorganisms in the Petri dish as enemies. However, the microorganisms behind the icon in the Petri dish will actively prey on other microorganisms! With their reproduction speed, it will take less than a day. We can replace the whole piece of miasma, and then we will You can go in with a swagger. "Yak shrugged and said that it was so simple. It was not soul force at all, but it was very scientific.


    "Well, we are here to investigate biodiversity. Why did we just make complaints about genocide?" Liu Tianxin Tucao, but it is also clear that the mutated microorganism is actually very different from the original ecological structure and gene level, but only changed the identification of friend or foe. It can even continue to coexist with the plant spirits here.


    The replacement process of the new generation of microorganisms was very smooth. One day later, the UAV that once again dived into the poison gas, such as entering a no man''s land, smoothly arrived inside the eyes of ice and fire, and transmitted the internal scene.


    "It doesn''t look like a problem." they smeared pheromones on their bodies and checked that their weapons and vehicles were in good condition and had been wrapped by pheromones, so they set out to the interior of the ice fire Liangyi eye.


    "Green scale seven Jue flowers! It is said that they are very suitable for the soul of the plant system. They can have the same strong toxicity as him after absorbing his soul ring. However, in our previous conclusion, the toxicity of this flower should come from the microorganisms symbiotic with it. Is it difficult? After absorbing this soul ring, the human body can symbiotic with this microorganism?" the shadow muttered.


    "It''s possible that the rules of soul power in this world are different from those in our past, so I''m not sure whether the operation principle of soul ring here is the same as that in our past?


    That''s it! Speaking of it, it''s still a bit dangerous for us. There are no fewer than ten hundred thousand year old soul beasts in the valley. Fortunately, the plant system, the soul beasts are not very aggressive, and the territory is relatively narrow due to the limitation of mobility. They basically won''t face two 100000 year old plant system soul beasts at the same time. "Yak took the lead in getting off the bus.


    From here to the sky, you can see the clouds shrouded in colorful fog. The sun shines down from the clouds and becomes colorful, just like a fairyland.


    "Who are you? Why did you break into our territory?" a big pink flower suddenly vomited, turning their eyes.


    "If I guess right, this one should be Youxiang qiluolan." Liu Tianxin touched his nose and always felt a little scary. It was a flower without nose and eyes. It''s a little scary to imitate the action of opening your mouth and opening your mouth to you, even if the flower was pretty good. It''s scary to move like this.


    "Hello, we are members of Douluo biodiversity research group. We are here to investigate the biodiversity situation here. We hope you can cooperate with our investigation to accumulate valuable experience in managing ecological disasters in the future."


    Fragrant Qi Luolan: "??"


    He thought that he would be the man in the Tang gate. If so, if he had been tested, he could take seven kinds of immortal grass from here. If he were a wise beast for 100 thousand years, he could take away their essence.


    But these two people are obviously not from Tangmen. And it looks easy to come in. This really can''t help but make Huaxin doubt.


    "We don''t welcome strangers here. If you are from Tangmen, please prove your identity. If you can prove it, you can take seven kinds of fairy grass from here. If not, please leave. I don''t want to use force here."


    Liu Tianxin heard the speech, patted the hood and said, "in fact, we don''t mind using force at all. If you don''t believe it, you can try it. Look at the power of your 100000 year old soul beast and the power of a small cold nuclear fusion reactor. Who is the bigger? I''m also very curious, so I brought a lot of spare nuclear fuel with me. I hope you can meet my curiosity."
