"Hiss......" took a cool breath, Zhao Mu was very glad that he had the opportunity to make a decision and come over to investigate it in person, otherwise, if he didn't prepare anything, Nanguang City would really be directly attacked by these newly appeared red-skinned monsters.

When Zhao Mu saw these red-skinned monsters flying up densely, he immediately understood that the natural advantages of human beings were no longer there from today.

In the past, human beings relied on many means such as city walls and base defense, but Ansheng survived the most severe period of development and recovery.

That's because among the monsters on the other side, there are no flying monsters, but now they are far different.

Based on the number of these flying monsters, Zhao Mu had no reason to think that human beings could still have an advantage now, even if there were such big weapons as aerospace fighters and armed helicopters.

One qiē just because of the number of these fighters, it is too small.

In the sky, a bird can also crash a fighter, Zhao Mu really can't imagine what kind of air and space fighters will happen when these monsters pounce all over the sky.

"Let's go." After getting this discovery, almost without a word, Zhao Mu turned around and left, he used his extreme speed to escape as fast as a meteor in the extremely fast round trip.

At the same time, six meteors were instantly summoned and circled around him, but whenever there were flying monsters with eyes that did not have long eyes, they were immediately killed by the six satellites that surrounded him autonomously.

The whole process didn't need him to be distracted to operate, and the level power of the four meteors and the level of the six meteors had a qualitative leap.

Whether it was his own defense or a surround attack, Zhao Mu's surroundings had become an absolute realm, and in the tacit cooperation of the six satellites, the flying monsters that kept coming up from the forest below were all in vain.

It didn't take long for Zhao Mu to kill a bloody path in the countless flying monsters. Easily escaped from the skies above the forest.

If other abilities, or even second-level abilities, saw this scene, they would definitely be very shocked, because the strength that Zhao Mu showed at the moment was too exaggerated.

With the power of one person, he killed hundreds of flying monsters and broke through from the countless flying monsters that pounced on him, this calmness and strength is really not something that ordinary second-level abilities can do.

After returning to Nanguang City, Zhao Mu immediately released a lot of targeted preparations for flying monsters. At the same time, he finally went to the Nanguang City Research Institute.

In order to keep Nanguang City, it is obviously far from enough to rely solely on some ground-to-air conventional guard forces, even if it is to produce anti-aircraft guns, anti-aircraft guns and other ammunition 24 hours a day, it is not enough to withstand the number of attacks of these monsters.

More than ten years have passed, and these alien monsters have actually taken root and sprouted, and they themselves are like human mating and breeding. There are already more than human breeds.

The amount seen on the ground is only a part of the surface, and the real base camp of monsters actually comes from underground.

That's right. It is the underground world, and their ancestors were actually found alive by humans from the underground world.

"Dean, I told you about your full research project a long time ago. Has there been any progress now? As soon as Zhao Mu entered the research institute, he was not polite, and asked straight to the point.

Now it's about everyone's safety. He also cared if he would offend the old madmen, and if they dared to play tricks on him at this time, he would not hesitate to throw these fellows into the forest, and feed them all to the skinless monsters.

Since it's useless, what else do you deserve special treatment?

"The progress is not ideal, we still lack some kind of resources, but your military people have been refusing to relax the restrictive supply...... "The old dean is still the same as before, and he doesn't care much.

With a "bang", Zhao Mu didn't want to listen to this old guy, so he directly let go of his hand and threw the corpse of a red-skinned monster on the workbench.

Such a big movement instantly caused the surrounding researchers to pay attention to it, and a trace of consternation rose on their faces, you know, in the past, the people under the city lord had never had this attitude.

But when they saw the monster on the stage, everyone's faces changed.

"I tell you, I can resist them for five more days, after five days, if you can't come up with useful means, then all mankind will wait for death, and I will also throw you into the monster group as soon as possible......" Zhao Mu sneered and looked around repeatedly, and then said nothing more, and left.

For these talented and proud guys, Zhao Mu is not the head of the previous city lords, and frankly speaking, Zhao Mu doesn't need to rely on them too much.

If the monster group really breaks through the whole city, it will definitely not be Zhao Mu and the others who will die.

At most, Zhao Mu admitted that the limited world challenge failed, and returned to the real world with the three daughters without gaining anything.

Of course, if he did this, not only would Zhao Mu not be able to obtain the precious magic shaft fragment, but he would also miss the rare opportunity to limit the world only once in the five worlds, so he would not do it until the end.

But now, it has reached the most critical moment, and Zhao Mu has nothing to think about.

"Wait...... You mean, they've evolved to breed these massive species of flesh-winged monsters? And they're ready to attack our Nanguang City? ”

This time, the people in the research institute finally panicked.

"What do you think? Iron Eleven, you show them the movements of the monsters you investigated earlier. ”

A moment passed.

The entire research institute finally had to admit that the whole city had fallen into an unprecedented crisis, and at this time, these guys had finally come up with the most core research and development results.

"This is the research result you asked us to do three years ago, it can effectively kill these monsters in large quantities, we have tested it repeatedly, as long as it is a red-skinned monster, it is almost not much resistant to it, even if the purple-skinned monster is contaminated, their strength will be weakened and reduced to seventy percent, as long as there is a large number of germ source bodies, with the underlying productivity of our Nanguang City, it can definitely be manufactured in large quantities in a few days."

After hesitating for a while, the old man of the dean finally carefully took out a thing and handed it to Zhao Mu, and there was also a detailed preparation information for such a thing.

After Zhao Mu took it and got his hands on it, he just glanced at it, and handed it to Tie Shiyi beside him, asking him to take it back quickly to check and verify.

If this thing is really as effective as the other party said, then the means to deal with these monsters are finally available, and Zhao Mu quickly solves the challenge of this limited world, and he directly has a great hope of shortcuts. (To be continued.) )
