The main combat flying saucer used to deal with the endless number of insect soldiers was severely damaged by the self-destruction attack of tens of millions of explosive flying ants. ¡òThe landmines laid in space have also been cleared to the fullest. This time, the three-community alliance command force that had just responded was in a huge headache. Perhaps the only way to effectively deal with the large number of velociraptors and hydralisks was now. That leaves only the thunder matrix network of the Thor ship and the audio pulse missile of the Tianyin ship. However, the number of insect soldiers accumulated by Li Feng was still too many, and Li Feng soon discovered the real weak cover against these frigates. That¡¯s their engine. There are many reasons why the second-level civilization battleship can only be regarded as a star battleship and not an interstellar battleship. The most important difference between the two is that the former can only sail within the star field and cannot support crossing the galaxy, let alone directly sailing out of the current galaxy universe. But interstellar battleships are different. Starting from entering the third-level civilization, they already have this interstellar space capability, so they are called interstellar battleships. The second big difference is the protective cover. Although the protective cover of a third-level civilization warship has a relatively single function, as long as the warship still has energy reserves, this means that it is still protected by the protective cover. You I can't stand it destroying it at all. But the interstellar battleships created by the second-level civilization do not have an energy protective field. Therefore, their battleships can only rely on simple material armor to defend themselves. So when it comes to the fatal weakness that can only rely on armor for defense, the question arises. Starry sky battleships without protective covers mean that their appearance is not dense and perfectly protected, such as power engines? This is an engine that must spray outward to form a recoil force, and it is destined to have an injection port. And now. Li Feng's sudden change in tactics was related to this point. Under his command adjustment, all the swift dogs that rushed close to the frigate no longer acted like fools, frantically ramming into the opponent's thick and difficult-to-break armor. Instead, they all circled behind the engine exhaust holes of these frigates. He took an extreme and suicidal approach and drilled into the engine mouth desperately. Even though these fierce dogs had just gotten in, their hard and strong bodies were melted by the high-temperature gas ejected from the engine, but they still kept getting in. There is only one purpose, and that is to block the power excretion system of a large number of fierce dogs through their bodies. Sure enough, this method had a great effect in an instant. In less than half a sound, the entire starry sky ushered in huge explosions one after another. These are the frigate engine ports that are blocked. As a result, the heat energy cannot be discharged from the body, resulting in continuous compression and eventually an explosion. "It's over, how could this happen?" At this moment, the commander-in-chief of the three clans of the newly born and weak monster and insect civilization, who originally didn't pay much attention, suddenly turned pale. The three tribes have prepared so many insects to deal with extremely large numbers but relatively small sizes, just to prevent this. But now, after many battles with tactical changes by both sides. Several commanders understood at this point that they had lost. The opponent has now clearly identified their fatal weakness, and used a very weak self-destructing flying insect in huge numbers to defeat their previous combat method of dealing with small insects. "Fire, fire for me. Fire with all your strength, we can't let the frigates continue to be lost. Kill these disgusting little bugs with all your firepower, leaving no unit behind." Finally, the commanders of the three tribes no longer had the relaxed thoughts they had before. . They gave the order to open fire across the board. What does it mean to open fire across the board? This means that all fleets will no longer save ammunition and use all their strength to kill these small bugs and kill these large and continuous seas of bugs. The order to attack the mosquitoes with all-out artillery was the only option that the commanders of the three tribes had to discuss as soon as possible. Otherwise, once all the numerous frigates are killed by these little bugs, and only large star cruisers, god ships, guardian ships, and battleship-level main ships are left, their situation will be dangerous. Although the firepower and main gun damage of these large battleships are very overbearing, they also have the weakness of engines and ammunition limitations. Once all the frigates are destroyed, even if these large armed ships reserve more ammunition, they will still have the potential to run out of ammunition one day in the face of the endless sea of ??insects. The current plan is that they can only use large firepower ships to launch fire?Support and in turn protect these large numbers of frigates. It has to be said that several warships with high density and powerful firepower joined in the firing without reservation. Suddenly, Li Feng felt that his insect soldiers were dying at an alarming speed. The number of insect swarms killed by these powerful secondary guns and scattered cannons every second counted in the hundreds. . Within a few minutes, all the velociraptors under Li Feng's command, as well as the dispatched snake-striking troops, were dead. However, Li Feng didn't feel any heartache at all about this situation. Finally, when he saw the fleet of the opponent's three-tribe alliance firing at full strength for about ten minutes. Li Feng finally dispatched the flying dragons that he had not escorted out. A large number of thunder dragons and poisonous dragons rushed towards the rear like an overwhelming black pressure. The expressions of all the alliance soldiers driving and operating the battleships changed drastically. They know that the main force of the new monster insect civilization in front of them has finally been dispatched, which means that the next battle may be more difficult. Although these flying dragon troops are still not considered to be powerful monster insect troops when seen from a distance, they have obviously changed a lot from the velociraptors and snakes that were dispatched before. At least a discerning person can tell that the level Completely different. It is at least two levels higher than the previous cannon fodder unit. Sure enough, when the fleets of the three tribes opened fire against the incoming flying dragons, many soldiers felt a sense of gloom in their hearts. The insect soldiers dispatched this time could no longer be bombarded to death over and over again. Instead, they still retained their tenacious vitality and rushed over to the starry sky area in the center of the bombardment, continuing to advance towards their fleet. Often a salvo of secondary artillery will hit these flying dragons at least two or three times before their bodies can be completely blown to pieces. And the maneuvering speed of the flying dragon group was far beyond that of the previous low-level units. In just a few minutes, a large number of flying dragons attacked from all directions. They started the real attack, with lightning jets, venom spitting and splashing damage. In an instant, the outermost frigates began to suffer a lot of damage. " Taking advantage of their illness to take their lives, a sneer rose from the corner of Li Feng's lips, and another instruction was conveyed.
