Humans developed things like pyrethrins because they had suffered from high-residue chemical pesticides, such as ddt, 666 and ddvp. They were almost all poisons that harmed both humans and pests. It is not troublesome for Dragoon Magic Industrial to obtain a large amount of pyrethrins through the Dragoon Consortium. After all, this highly efficient insecticide is not a weapon of mass destruction. As long as you give money, it can be obtained all over the world, not to mention that the Dragoon Consortium itself has certain The demand for pyrethrins, whether for agriculture or household use, is large. The additional order for 1,000 tons of pyrethrins is not conspicuous among imported and exported materials. "Get ready to open the passage! Take turns to open the way!" After receiving Lin Mo's assurance, Dragon King Igfisro finally felt relieved. From the time Li Muchin proposed to the diluting mist of pyrethrin that penetrated deep into the spider cable area, the humans and dragons never even considered calling out the metal dragons. Unless poisonous mist can cause strong corrosive effects on metal, it will be ignored by the metal dragons. o, the mist used to kill insects was poured directly into the crisscrossing spider cables without any scruples. In fact, the metal dragons didn't care at all. Dragon King Igfisiluo, the battlefield commander, gave an order, and the intelligent species with cutting skills quickly gathered together. Most of them were warriors, with demons, orcs, spirits, feathers and Mainly human race. With the incomparably sharp blade and the blessing of fighting spirit, the human sword god is just right against these tough spider cables. With seven or eight full strokes, he can cut off a spider cable neatly, and the effect is excellent. Whether it¡¯s a wind blade, a weapon blessed with war energy, or a space blade, all kinds of methods are used. Without the harassment of those giant colorful spiders, the work of cutting off those spider cables has become much smoother. After being contaminated with pyrethrin diluted mist, the surface of the spider cable was stained with a light pink color and unexpectedly lost its original strong stickiness. This makes cleaning up after cutting a lot easier. The severed spider cables were not discarded at will, but were gathered together and put into a vacant super-large-capacity space-based alchemy storage. The underground world is home to all kinds of incredible creatures, and it also contains all kinds of incredible natural resources. The work of collecting resources along the way is essential. If you study these biological fiber complexes, which are composed of countless ultrafine fibers twisted together by themselves, you may be able to gain something. Although they have not been sent to the surface world, you can already speculate on the suitable uses of these spider cables. There is strength in numbers. The spider cables were cut one by one, and the mountain-like spider cables were taken away on the spot. The giant dragon clan and the heavenly supremes of various intelligent races finally cut out a passage about 1 kilometer wide in the spider cable area, and Deepening. The pink mist continues to spread. One ton of pyrethrin mixed with four tons of high-purity alcohol forms a powder mist that is enough to fill tens of thousands of cubic meters of space. Coupled with the further vaporization of the suspended droplets, the expanded volume will be enlarged to a hundred times. As mentioned above, with the natural movement of airflow, it is possible that it may even spread to every corner of the entire spider cable area. Wherever the pyrethrin mist swept away, a faint sweet smell filled the air. As Lin Mo said, apart from mild allergic reactions on the skin surface of some intelligent races, this synthetic chemical pesticide is indeed not toxic enough to pose a threat. However, this sweet scent, which is similar to the fragrance of flowers, means disaster for the giant colorful spiders that live here. They will be killed if they touch them, and no one will be spared. After sacrificing nearly a thousand spider lives, the colorful spiders finally learned to be smart and knew that the pink mist surging everywhere was not easy to deal with. They were so frightened that they peeed and fled further away without looking back. ??At least for a long time. These native arachnid species no longer have the guts to challenge uninvited visitors from the surface world. The illumination light ball suspended in mid-air cast a soft white light, and the pink color on the surface of many spider cables gradually faded away at a speed visible to the naked eye, including the strange sweet smell that also dissipated a lot. Pyrethrin has a certain light-sensing property, which is close to the light of the holy sun. Just like adding a catalyst, the degradation rate naturally accelerates. There is still some weak toxicity left, but there is not much left. It took a full 12 hours, but the dense spider cable area was finally broken through. Looking at the dark area on the opposite side, there was still no light at all. All intelligent races, including the giant dragons, felt relieved in their hearts, like a big stone finally falling to the ground. It took 12 hours to cut through thorns, and the internal fighting among the gold-type dragon clan lasted for 11 hours. These guys were really not tired. During the chaos, many spider cables were cut, allowing the people of all clans to clear the way. After spending a lot of effort, Silver Dragon Law Enforcement Captain Tesepalia was determined to deal with these stupid dragons, but for a while he couldn't find enough reasons. ?????????????????????????These guys who started fights were not just fighting. Whether intentionally or unintentionally, if you only look at the results, they still contributed to opening the way. Not long after the team successfully passed through the Spider Cable Zone, a bottomless and endless abyss blocked the front, becoming a new obstacle to crossing this dark zone. In fact, the entire team had to stop when they were still two kilometers away from the abyss. "The crack in the ground that lies in front of all the intelligent species is constantly echoing with a soul-stirring and shrill sound, like the howling of ghosts and wolves coming from the depths of hell, making people feel horrified from the bottom of their hearts. Most intelligent species feel that their mental power is becoming uncontrollably chaotic at the first moment. It seems unbelievable that such an impossible thing happened to these intelligent species. It must be known that most of the intelligent species involved in the operation are heavenly supreme beings. In the absence of specific serious injuries, no matter what, There is no possibility of chaos caused by mental fluctuations. The air near the abyss in the ground trembled inexplicably with that weird sound. Even if you cover your ears and block your hearing, you can still feel an invisible vibration like a tide, continuously sweeping through you. It was as if it was pulling this body to resonate with it and fall into that extremely weird rhythm. "The dark zone is really very troublesome!" Dragon King Igfisiluo controlled the surrounding wind element energy and teamed up with other spell casters to release a huge wind spell shield, and a shrill sound poured out from the abyss. Completely isolated from the strange air fluctuations, the chaotic mental power of most intelligent species gradually calmed down again. "Igfisiluo, why don't you move forward?" Hitamaiyas, the current leader of the gold dragon clan, did not stop moving forward with her own clan, flying more than a thousand meters away, and then discovered other giants. The dragons and the supreme beings of various tribes did not follow. A group of giant metal dragons with scarred bodies turned back, not knowing why. "Hitamayas, didn't you hear the sound?" The Dragon King's voice passed through the magic shield and spread far away. As soon as the words were spoken, Igfisro reacted immediately. Where do the gold-type dragons get their spiritual power? Other people's mental power will be disturbed, and even if they want to be disturbed, they don't have the mental power to do so. "I heard it! It's just a bit noisy, it's nothing!" Sure enough, everyone from Hitamaiyas to any of the giant gold dragons were completely unaware of the incredible interference and had no mental power. Naturally, Just be immune. "It seems like the 'Eye of the Lich' can't fly over!" Silver Dragon Law Enforcement Captain Tesepalia saw several silver balls swaying above the cracks in the ground, seemingly unable to stabilize. "I'll go over and take a look!" Dragon King Igfisiluo flapped his wings and rushed out from under the protection of the huge wind spell shield in the blink of an eye. The moment the dragon body broke away from the spell shield, the cyan wind element around him There was another crimson light among the energy rays. With the dragon's physique and the energy talent of the wind and fire dual elements, he is able to suppress the fluctuations in mental power. Before it could fly close to Hitamaiyas, a "Lich Eye" finally couldn't hold on any longer. The faint blue light of the magnetic plasma engine at the tail suddenly went out. It lost power on the spot and fell from mid-air, heavily. It hit the ground, followed the slightly sloping terrain, rolled towards the cracks in the ground, and finally fell headlong into the endless abyss. "Another 'Lich Eye' has been lost, this is already the sixth one!" Even though she knew that the hostesses would not blame her, the maid who lost contact with the "Lich Eye" still turned pale and looked miserable. . The screen showed that the signal of the "Eye of the Lich" that fell into the abyss was completely interrupted, and attempts to initialize the signal link were never successful. "It doesn't matter! Call back the 'Eye of the Lich' in front and let Mo Lin and Gold Coin do the reconnaissance!" Li Muxin rushed over and comforted the little maid who started to burst into tears. After all, they are not real military personnel. Although they have mastered some skills, their psychological quality cannot be developed in a day or two. "Yes! Kokoro-sama!" Holding back her grievance, the maid quickly began to deliver the message. When a "Lich Eye" near the crack in the ground was about to be recovered, the shaky optical lens suddenly stabilized. Although the communication link has not been interrupted, warnings are being issued continuously that the flight attitude is out of control, which is completely contrary to the system's automatic stabilization signal. ? ? ? ? ? ? ? ? ? ? ? ? ?While the ship was confused, the optical lens began to automatically refocus, and a huge dragon head appeared in the transmitted picture. Is it Dragon King Igfisro? ! The light cyan and red dragon scales distributed in a certain symmetrical pattern make it easy for people to identify each other. The "Eye of the Lich" once again lost control and seemed to be related to the Dragon King Igfisro. If the guess is correct, this unmanned reconnaissance vehicle is in the opponent's claws. ¡ª¡ª (To be continued.) Mobile phone users please visit http://m.piaotia.net
