"Hiss..." After taking a breath, Zhao Mu was very glad that he made a quick decision and came to investigate in person. Otherwise, if he had not prepared anything, Nan Guangcheng might have been directly attacked by these newly emerging red-skinned monsters.

When Zhao Mu saw these red-skinned monsters flying up, he immediately understood that human nature has no more from today.

Before, humans relied on many means such as city walls and base defense, but Ansheng survived the most severe period of development and recovery.

That is because among the monsters of the other party, there are no flying monsters, but now they are far different.

Just based on the number of these flying monsters, Zhao Mu had no reason to believe that humans can still have an advantage now, even if there are such great power as aerospace fighter jets and armed helicopters, it would not work.

All is just because of the number of these fighter jets, which is too small.

While flying in the sky, a bird can also crash the fighter plane. Zhao Mu really couldn't imagine what other aerospace fighter planes would be like when these monsters rushed over.

"Let's go." After getting this discovery, Zhao Mu turned around and left without saying a word. He used his extreme speed to escape as fast as a meteor.

At the same time, six meteors were summoned instantly and surrounded him. Any flying monster with no eyes rushed over and was then killed by the six satellites.

He didn't need to be distracted from operating the entire process. The power of the four meteors and the levels of the six meteors have simply qualitatively crossed.

Whether it is his own defense or circumvention, Zhao Mu became an absolute domain. With the mutual tacit cooperation of the six satellites, the flying monsters that kept pounced on the forest below were futile.

Not long after, Zhao Mu rushed out of a bloody road by countless flying monsters. He easily escaped from the sky above the forest.

If other abilities, or even second-level abilities, were definitely shocked to see this scene, because the strength Zhao Mu showed at this moment was too exaggerated.

With one person's strength, he killed hundreds of flying monsters and broke through countless flying monsters that pounced on him. This calmness and power is really beyond ordinary second-level abilities who can do it.

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

To protect Nan Guangcheng, relying solely on some conventional guard forces from the ground to the air is obviously far from enough. Even if you fully produce ammunition such as anti-aircraft guns, anti-aircraft cannons and other ammunition twenty-four hours a day, it is not as good as the number of attacks of these monsters.

More than ten years have passed, and these alien monsters have actually taken root and sprouted. They themselves are like human intercourse and reproduction. They have long been more numerous than humans.

The amount you see on the ground is just a part of the surface, and the real base camp of the monster actually originates from the underground.

That's right. It's the underground world. Their ancestors were actually discovered and restored by humans from the underground world.

"Sir, I have explained your full-scale research project a long time ago. Is there any progress now?" Zhao Mu was not polite when he entered the research institute and asked directly.

Now there is a safety for everyone. He also cares if he will offend these old lunatics. If they dare to play tricks for themselves at this time, he will throw these guys into the forest without hesitation and feed them all to the strange-skinned monsters to eat.

Since it's useless, what qualifications do you have to get special treatment?

"The progress is not ideal. We still lack certain types of resources, but your military personnel have always refused to relax restricted supply..." The old dean still continued as usual and did not care much about it.

With a "bang", Zhao Mu didn't want to hear the old guy say more, so he loosened his hand and threw a red-skinned monster body on the workbench.

Such a huge noise instantly caused the researchers around them to pay attention, and a hint of shock appeared on their faces. You know, the city lord had never had this attitude in the past.

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

"I tell you that I can resist them for five days. After five days, if you can't use useful means, then all human beings will die, and I will throw you into the monster group as soon as possible..." Zhao Mu sneered and looked around, then said nothing more and left.

For these talented and proud guys, Zhao Mu is not the leader of the city lord in the past. To be honest, Zhao Mu does not need to rely too much on them.

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

At most, Zhao Mu just wanted to go all out and admitted that the challenge of the limited world failed and returned to the real world with the three girls without gaining anything.

Of course, if you do this, Zhao Mu not only cannot obtain the precious magic axis fragments, but also misses a rare opportunity to have a limited world in five worlds. Therefore, he will not do this until the end.

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

"Wait...you mean, they have evolved and reproduced these large numbers of meat-winged monsters? And they are still ready to attack our Nankwang City?"

This time, the people from the research institute were finally panicked.

"What do you think? Tie Shiyi, let them see the monster movements you investigated before."

A moment later.

The entire research institute finally had to admit that the whole city has now fallen into an unprecedented crisis. At this time, these guys finally came up with the most core R&D results.

"This is the research result you asked us three years ago. It can effectively kill these monsters in large quantities. We have repeatedly tested it. As long as it is a red-skinned monster, it is almost not very resistant to it. Even if the purple-skinned monster is contaminated, their strength will be weakened and reduced to 70%. As long as there are a large number of bacterial sources, with the foundation and productivity of our Nanguang City, it can definitely be manufactured in a large number in a few days."

After hesitating for a while, the dean finally took out a thing carefully and handed it over to Zhao Mu, and there were also detailed information on such things.

After Zhao Mu took it, he took it and just glanced at it and handed it over to Tie Shiyi beside him, asking him to take it back for inspection and verification as soon as possible.
