PS. Present the May Day update, don't hurry up to play after reading, remember to vote for the month first. From now on, you can enjoy double monthly passes for the 515 Fan Festival, and you can also take a look at other activities with red envelopes!

With the shooting of various firepower, the mud shells smeared by the wasps at the gate of the institute were shattered, and almost in an instant, the wasps performed a "stabbing hornet's nest" for the people of the Central Continent team, only to see large and small wasps swarming out of the hive, because the density is too large, it looks like smoke cans are smoking.

At first, it was a palm-sized wasp, and the wasps in the back are getting bigger and bigger, even as huge as an adult's entire arm, and the wingspan of its wings is more than one meter, with yellow and black colorful patterns, which is very amazing.

It's a pity that the concentration of this smoke is enough, but the durability is too poor, seeing the giant wasp fly out of the hive less than 200 meters, they fell to the ground one after another, twitching their bodies, but the smaller wasps can rush out of a distance more, and their movements are much more agile.

"It seems that small wasps are a little more tolerant to poison gas?" After a long time, even Zheng Zhan saw the abnormality.

"Insects do not have lungs, and their breathing relies on the stomata scattered throughout the body and the trachea inside the body to transport air to all places, which is far less efficient than the blood circulatory system of vertebrates, so the body size is limited by the distance that the trachea extends outward from the stomata. In general, the higher the oxygen level, the larger the insect can grow. ”

"But at present, the size of these giant wasps obviously exceeds the limit of the supply of oxygen in the atmosphere, and the wingspan of the largest insect giant vein dragonfly that has ever appeared on the earth is only 75 centimeters, but the oxygen content of the air was nearly 30% at that time, and now the oxygen content of the air is only 21%, which is nearly half higher than the oxygen content now, and it has not grown into the size of these giant wasps, so either they have evolved a more efficient oxygen circulation system, or they have improved the efficiency of oxygen use by body cells."

"Whether it's a more efficient oxygen circulation system or an improved utilization efficiency, the former means inhaling a larger amount of toxic gas, while the latter reacts with toxic gas more efficiently. So ......"

At the same time as Li Xiaoyi spoke, a thick layer of wasp corpses had accumulated at the entrance of the research institute, but the wasps were still pouring out!

"That's what I'm worried about, the number of wasps. If it is too much, I am afraid that when the time set by the Lord God is up, we will not be able to enter. Chu Xuan said, just wearing an oxygen mask, which sounded a little stuffy.

"One hole is not enough, so we can open a few more, as long as we are careful to avoid the main body of the building," Li Xiaoyi said. The pulse muzzle of the mobile armor was also lowered, if it weren't for the main god's request to find the research notes, he was afraid that the research notes would be damaged, otherwise Li Xiaoyi would have dismantled the research institute alone.

"And what if there are too many holes and the queen bee runs away?"

“…… Let's go on for a while. ”

Fortunately, after more than ten minutes, the wasps gushing out of the hive finally stopped, and after such a long time, it is estimated that the poisonous gas has also penetrated into the research institute, but in the middle of this, Li Xiaoyi used plasma to treat the corpses of several wasps, otherwise the door of the research institute would be blocked.

Waited another minute. Seeing that there were indeed no wasps pouring out, the mobile armor took the lead, walking in the front, and Zheng Zha, Chu Xuan, and Zhao Yingkong followed closely behind.

As soon as I walked into the institute, the interior was pitch black, because the wasps had closed all the doors and windows of the building, and the whole inside was airtight, but fortunately, everyone wore glasses, so they didn't become blind.

The interior of the institute was filled with hexagonal hives filled with bee eggs and wasp larvae. Although there was no movement under the ravages of poison gas at this time, it was just that the beehives everywhere made people not even have a place to stay, and the mobile armor was even more pit by step, so it simply floated into the air. Anyway, the space in this research institute is large enough, even dinosaurs can fight in it.

After investigating the situation, Chu Xuan and Zhao Yingkong went to look for the research notes, Zheng Zhan was ready to find the queen bee's bad luck, and Li Xiaoyi stayed in the hall to support at any time.

It's just that Zheng Zha, before he took two steps, Li Xiaoyi saw several huge wasps flying from the ceiling. These wasps are larger than the previous wasps, their body parts are more than a meter long, and they are obviously not affected by the poisonous gas, all of them are alive and well, and it seems that the main god is also fighting to make trouble for them.

Because the body of the insect takes the path of the exoskeleton, just like the load-bearing skin of modern fighters, the advantage is that it can also play a supporting role while undertaking the functions of waterproof, dustproof, and protecting internal organs of the skin, simplifying the body structure, which is a good choice for small insects.

But where there are advantages and disadvantages, there are thousands of exoskeletons, but there is one thing that cannot be avoided, once the exoskeleton grows, it cannot change its shape, that is to say, it cannot grow with the growth of insects, so insects need to molt, abandon the old exoskeleton, and use a new exoskeleton, so as to adapt to the growth of the body, and insects are the same choice of crustaceans, such as the crab that my big foodie empire likes to see.

This is a problem, the new exoskeleton grows inside the old exoskeleton, so how do you grow a larger new shell inside the small old shell? The solution for insects and crustaceans is to soften the new exoskeleton, which is soft before the exoskeleton comes into contact with air, and when it comes into contact with air or external conditions after molting, the new soft skin will harden into a hard exoskeleton, that is to say, before the exoskeleton hardens, the entire internal organs of the insect are not supported, and for the bee, an insect with a strong sense of three-dimensionality, the trouble caused by gravity is particularly serious.

Looking at the super giant wasp in front of him, Li Xiaoyi couldn't help but sigh, he really didn't know what the Lord God asked them to eat to grow so big.

Suddenly, "A force field reaction has been detected!" A message was detected by the sensors of the mobile armor.

Force field reaction? Li Xiaoyi looked at the information thoughtfully, at this moment, Zheng Zha had already started to fight with the super giant wasp, and it seemed that he was still a little struggling!

It's just that the firepower of the pulse cannon is a bit too strong, and Li Xiaoyi is worried that it will damage the research institute, so he can only use two high-energy laser emitters to assist and interfere with the super giant wasps, because these wasps can actually carry the irradiation of high-energy laser beams!

Judging from the high-speed footage shot by the mobile armor, whenever the laser beam hits the giant wasp, there will be a faint light blocking the laser beam, no wonder these super giant wasps are so difficult to deal with, and there is a buff added by the main god.
