"So this thing is still alive?" Gou Cao carefully touched the pure black bud-like tissue in the petri dish with a glass rod, and the root filaments of the bud-like tissue immediately twisted and twitched relatively weakly.

"The main part died half an hour ago, and this is just a stress response of some nervous tissues and muscle fibers that are still active." He Hehe replied as he carefully picked up the bud tissue with tweezers and put it away in a glass container containing some kind of transparent liquid.

After defeating the zombie thrower, Gou Cao dismantled the rest of the aircraft structure, and asked others to help remove all the metal equipment in the headquarters and install it on the rover, although the others were puzzled, but after all, they were able to survive Gou Cao had a lot of credit, so they didn't say anything.

After that, he left there in a hurry. When he left, he collected their bud-like tissues and somatic cells as specimens and brought them to He Hehe for study, and then produced a batch of test equipment according to his requirements. That's why we have the scene just now.

What Gou Ke and his party encountered at the airport was very strange, according to He Hehe and Xiao Na's respective research. The relationship between zombie virus, bud tissue and zombie is parasitic and parasitic.

The zombie virus parasitizes the cells of a fungus that would otherwise only parasitize small insects, destroys the genetic sequence of this fungus, gives it the ability to parasitize large mammals, and gives it nervous tissue and muscle fibers, which can move autonomously to a certain extent.

The fungus mutated after parasitism was named zombie fungus by He Hehe, and the fungus of zombie fungi is divided into three parts, the main part is the bud body, and the intersection of muscle fibers and nervous-like tissues is mostly here. Outside the main body are hyphae, which are the kind of black silk threads. Mycelium is further divided into two categories, one is parasitic hyphae and the other is exophytic hyphae.

The parasitic hyphae are mainly responsible for absorbing nutrients from the host and exercising neural control over the host, which is the part that occurs when the zombie fungus is in its juvenile stage, that is, when the bud body is pure white; In the mature stage of the zombie fungus, that is, when the whole body turns black, exophytic hyphae will be produced, exophytic mycelium muscle fibers are more enriched, which can replace muscles to provide physical strength to the host, and the zombie thrower is because of a bunch of exophytic hyphae wrapped around his arm, so his arm strength is amazing.

Before the end of the world, some fungi themselves had the ability to parasitize small animals and control their behavior patterns, and this fungus became able to control more complex neural tissues after being parasitized by zombie viruses, thus indirectly strengthening the virus's ability to control zombie behavior.

Originally, because of the simple structure of the virus, it was impossible to control the zombies to carry out relatively complex actions, but this parasitic mode in front of me more or less broke through this limitation. And the degree of destruction of the brain region of the zombie parasitized by fungi is much less than that of the zombie brain region directly parasitized by the virus, which means that the IQ of the zombie under the control of this parasitic mode is higher than that of ordinary zombies. No wonder more complex tactics can be executed.

As for the role of the fungus nest of zombies found in the arsenal, He Hehe said that without more samples, it is impossible to draw detailed conclusions.

Cortana's guess is that the zombie fungus should be a mutation of some kind of cordyceps, so the reproduction mode of the zombie fungus has also inherited the special newness of the cordyceps.

The most famous example of Cordyceps is Cordyceps sinensis, which is native to northwest China and has high medicinal properties. There are also Cordyceps in other places, of which there are more than 190 kinds in China alone, but they can be used as medicine as a special case of Cordyceps, and some are even extremely toxic and will kill after eating.

Cordyceps fungus will control its behavior after parasiting its head in the soil, and then in the right season, the fungus will break out of the head of the insect and grow, and the host will die and become nutrients for the fungus.

Cortana believes that what Gou Cao sees through the camera is the result of the zombie fungus killing the host and growing out of the broken body.

Gou Ke heard a chill, fortunately he didn't go in person that day, and he didn't bring out the camera equipment sent inside, otherwise if this thing had begun to emit spores and was inhaled by himself, it would be difficult to guarantee that it would not be proliferated by zombie fungi in the respiratory tract, thus parasitic himself and turning himself into a zombie. Although immunity to zombie viruses can immunize the virus itself, it is difficult to immunize zombie fungi. It seems that I will have to bring protective equipment to search the closed area in the future.

After hearing Xiao Na's speculation, Gou Cao immediately told He He He and Hao Aiguo about this conjecture, and then built a disinfection room at the entrance of the villa under the guidance of Xiao Na and He Hehe. If someone encounters a fungal nest without respiratory protection, they must be quarantined for a few days.

Gou also specially produced a batch of respiratory protection with better sealing performance and protective clothing that must be worn when entering zombie-dense areas, which became essential equipment for survivors when they went out to collect. At the same time, the three Brave have also been improved, so that they have improved window protection and protection against spore dust. At the same time, it is also more convenient to clean.

The Rover has a nuclear, biological, and chemical defense function at the beginning of its design, and the new model of the Rover also inherits this feature, so it is not a problem to prevent spore dust. However, the crew compartment was modified to give it the ability to disinfect people and small equipment. At the same time, the airtightness of each module has been improved, so that if one part of the rover is damaged, the invading spores will not affect the other modules.

In terms of weapons, he learned the lessons of the confrontation with zombies at the airport, and modified the JS9 submachine gun and three-zero pistol in the hands of the survivors. The JS9 submachine gun is equipped with a heavy long barrel and a quadruple scope, which makes it have a longer range and higher accuracy, and can adapt to accurate shooting within 100 meters.

The 30 pistol, on the other hand, has a longer barrel and a detachable stock, and is equipped with a non-magnification holographic sight, which improves the range and accuracy while speeding up the aiming speed. Rapid reaction shooting is possible.

After seeing Gou Cao's excellent mechanical modification ability, everyone did not express too much surprise that Gou Cao modified the firearm to this extent.

As for the Type 47 military pistol and 5.8mm military pistol cartridges, Gou Ke did not provide them to the survivors, on the one hand, because he did not want to expose his ability to produce hot weapons in large quantities. On the other hand, it is more important to deal with zombies, while military ammunition is insufficient to stop and has a surplus of penetration, so there is no need to equip survivors.

As for the rover's weapon configuration, Gou Cao also has a more detailed plan.
