In fact, the ability of the three mutant insects is quite good, the ability of the big jumping foot insect is that the attack speed is extremely fast, the big jumping foot insect belongs to the grasshopper class of mutant insects, although they have no flight ability, but they have quite a good jumping ability, the strong hind limbs are enough to provide them with a huge sprint force, coupled with the sharp horns on the head and quite sharp claws, it makes these guys a headache for the spirit masters who are not very strong in defense.

The advantage of the multi-legged geosaurus is that the acid it spews is extremely corrosive, but the flat-headed nine-legged insect can spit out a tough, viscous filamentous substance like a spider, and the silk they spew out is sticky, and it is difficult to get out unless it is burned with fire.

The abilities of the three mutant insects are not bad, but Li Jieguan did not intend to use a heavyweight weapon like the magic cannon to deal with them, and in fact, the battle had already started when the insect tide was still a few kilometers away from the city.

In order to resist the mutant insect disaster once in thirty years, Li Jieguan made quite strict defensive measures in Guangmu City, in addition to the arrangement of these defensive means inside the city, in fact, some of them were arranged outside the city, and the most important arrangements outside the city were magic traps and spell mines.

In fact, the mutant insect tide had already lost a large number of them before it entered Wu Song's field of vision, and the faint rumbling sound that Wu Song heard before was the sound produced when the spell mine exploded, and after the baptism of the spell mine, the density of the mutant insect tide dropped significantly, and then, what they had to face was the hunting of magic traps.

In fact, strictly speaking, those spell mines should also belong to a kind of trap, but the defects of spell mines compared with other magic traps arranged outside the city are very obvious, although the power of spell mines is not small, but each spell mine can only explode once, in other words, this thing is also a one-time consumable, and it is completely useless after a bang, and the mutant insect disaster will last for a long time, and it is impossible to have the opportunity to go out of the city to make up for the mine after the mutant worm besieges the city. As a result, these spell mines are less useful, and some magic traps that can continue to kill mutant bugs are more advantageous in comparison.

The army of mutant insects gathered again at a distance of about three miles from Guangmu City, and then rushed towards Guangmu City with great momentum. Then, a series of silver-white nets of light were erected around Guangmu City.

After seeing the light net like a fishing net, those mutant insects only hesitated for a moment, and then rushed towards the light net, and what they didn't expect was that the light net woven by these rays was like an extremely sharp knife, and the mutant worms that hit the light net were cut into large and small pieces in an instant!

Although the mutant worm is not very developed, it is not stupid enough to hit the head with the knife knowing that it is a knife, and the powerful lethality of the light network makes the mutant worms rush to fear, and those guys forcibly stopped, as if waiting for something to arrive.

"Humph! Thinking that it would be okay if you don't go forward, start the active attack mode and teach Lao Tzu a hard lesson to those reptiles. Li Jie snorted coldly and gave the order again.

Those mutant insects flinched in the face of the powerful lethality of the light network, but soon they found that just not moving forward seemed to be not enough to save their lives, and the light network that was fixed in place suddenly pushed towards the direction where they were hiding at a very fast speed, and the mutant insects that were relatively close to the light network were cut into pieces by the light net because they did not run in time, and the mutant insects behind saw this scene and fled back like a tide, these guys collided with the mutant insects rushing from behind, For a time, the mutant insects trampled on each other, and countless deaths and injuries were innumerable.

The optical network stopped after chasing the mutant insects for a distance of about four or five hundred meters, the general control organ of these optical networks was in Guangmu City, although the lethality of the optical network was very strong, but there was no way to break out of the place that was too far away from Guangmu City, and those mutant insects who were chased by the optical network and fled one after another also stopped after seeing that the optical network stopped, forming a huge encirclement not far from Guangmu City.

"The space optical network continues to be maintained, and the thunder troops quickly go out of the city to lay mines, your speed must be fast, then the optical network will not be able to stop the insect tide for a long time." Seeing that the mutant insect tide was blocked on the periphery of the light network, Li Jieguan immediately sent people out of the city and laid a new batch of spell mines near the city.

The mutant insects gathered more and more around the light network, and after about twenty minutes, the insect swarm that had been silent for a long time stirred again, and soon a dense small black dot in the sky floated towards Guangmu City. In the center of the small black dot, there is a black object that is significantly larger than the others.

"What's that?" Wu Song turned on the Eagle Eye Technique (a level 40 skill used by thieves and hunters, the effect is to improve the user's eyesight, so that he can see farther and more clearly) and looked into the distance, and then couldn't help but exclaim.

Those small black dots were some flying mutant insects that looked like bats and had periosteal wings, Wu Song preliminarily estimated that those mutant insects spread their wings enough to be four or five meters long, but what was surrounded by a group of big bats was a mutant creature with a flat body and an extremely huge body. The mutant creature grew somewhat like a jellyfish, and under the huge head were countless tentacles hundreds of meters long, and above the tentacles, there were dense large bats.

"Damn, it's the Demon Wing Bat, aren't these guys arriving here at peak times, they rushed to the front so quickly, it seems that they are specially used to deal with the space light network." Li Jieguan sighed, he was no stranger to the Demon Wing Bat, although he couldn't figure out why these little guys who could only be teleported from the space-time wormhole during the peak period played the role of cannon fodder this time, but it was obviously not good to deal with this kind of little thing without showing some real skills, the old man shook his head, and immediately shouted loudly, "Pay attention to Lao Tzu, those Demon Wing Bats are specially here to deal with the space light network, and the poisonous mist emitted by that thing is a big trouble, when I say withdraw later, You must remove the space optical network for me as soon as possible! ”
