The three of them rushed to Beiwai City with the guards who reported the news.

At this time, the gate of Beiwai City was just as the guard said. Countless bugs as big as rats were breaking through the blockade of the Fire Niucheng formation and rushed into Beiwai City frantically. The chassis of these bugs was very low and not big. As they moved, they were still shining with various lights, which were extremely eye-catching.

It is precisely because these bugs are so eye-catching that they were discovered by residents as soon as they entered Beiwai City.

"It's over! Why are the bugs coming in!"

"It hurts so much! Why are these bugs so hard!"

"I'll kill you!"

"Bang"

"Why does this thing hurt more than a stone when you explode on your body?"

Seeing that the city was messed up by these bugs, Tang Huoniu couldn't stand it anymore, so he raised his hand and raised his two fire bulls and rushed towards the flashing bugs.

After a while of collision, the fire bull dispersed and turned into countless fire balls that emitted hot and high temperatures.

But these flashing insects were like walking on flat ground in the fire ball, without any effect while walking, and even the light on their bodies became brighter.

Tang Xihe said anxiously: "Oh no, these bugs are really not afraid of the high temperature. It seems that they can only fight head-on."

Tang Huoniu frowned, raised his hand again to call out a Huoniu. He jumped up and rode up, trampled towards the insect swarm.

But at this time, Chen Wangping raised his hand to stop him and said, "Uncle, you can't just go there. After you roast the fire beef just now, the explosion of these bugs will be even stronger. If you go in rashly, you may be injured."

As soon as he arrived here, he found the closest position to the formation and observed it. After changing several positions in a row, he found that the light on the bodies of these insects was not emitted by himself at all.

It is the minerals on their backs, or stones.

These bugs either feed on minerals or use minerals as protective shields like hermit crabs. In short, there is a thick layer of translucent minerals on their backs.

Under the light, these minerals reflect various flashes, and at the same time help these insects withstand the high temperature. Moreover, after killing the insects, these minerals will explode and cause secondary damage.

It can be said that this kind of insect is the nemesis of the Fire Niucheng Formation, and it is very difficult to deal with.

Previously, it was difficult for people from Huo Niucheng to solve this kind of insect in battle. Even if they hit the stone, they would not be able to cause any results.

Moreover, he also observed that these bugs immediately drilled around after entering the Fire Cow City. Injuring people was only secondary. Their main purpose was to enter the underground of the Fire Cow City, and their goals seemed clear.

Hearing Chen Wangping's words, Tang Huoniu stopped and turned around and asked, "Big nephew, what do you think you should do? If so many insects really get into Huoniu City, then I don't know how many people will die."

If there are no residents, what is the city of Huoniu City?

Chen Wangping attacked a bunch of bugs that had just rushed in and said, "When I study it, you can use a bunker to block these bugs first, they don't move that fast."

After saying that, he stared at a stone worm the size of a palm and rushed over, and glanced at the shape of the mineral behind the thing, which was very flat and bare.

As Chen Wangping looked at it, he thought of the structure of tempered glass. He tried to point it at the edge of the stone worm's back and shot out an electric light, specifically to hit the corners.

"Bang"

Something surprising happened.

The lightning hit the edge of the back of the stone worm. A piece of mineral was blown up instantly, and the body of the worm under the mineral was also exposed.

Effective!

Chen Wangping smiled with satisfaction, took out the submachine gun and pointed it at the exposed insect body, and instantly the insect was thrust blood all over and twitched.

"Sizzy!"

The painful stone worm turned around and ran away, preparing to use its body to escape from the Fire Niucheng Formation again.

Chen Wangping glanced at the direction of its escape, and instead put away the submachine gun and followed behind and waited.

Just as the stone worm passed by the hot Fire Niucheng Formation again, it suddenly twitched all over, stopped at the edge of the formation, and ignited all over, and in the blink of an eye it turned into a charred insect corpse.

Chen Wangping smiled and said, "I want to run out without the mineral protection behind it? I will burn you to death."

He turned around and shouted, "Uncle, stare at the edges of the stone shells behind these insects, don't hit the middle. If you knock off the stone shells, you can solve them with high temperature."

The guard next to him was still a little puzzled and said in confusion: "Is there any difference between hitting the edge and hitting the middle? The shell of this stone is very hard. We tried several brothers before but couldn't smash it, but they were hit and injured."

Tang Xihe didn't say anything, took out a soft whip with his hands, aimed it at the edge of a stone worm that had just rushed in and smashed it.

The whip hit the edge of the stone behind the stone worm as soon as it rose and fell, and immediately smashed a small piece of stone like Chen Wangping before.

Although not many stones were smashed, this is a breakthrough.

Immediately afterwards, she raised her hand and raised the fire python. The fire python rushed to the stone worm, stretched out her head and bit heavily on the exposed worm body, and instantly ignited it, turning it into a pool of charred insect corpses.

Tang Huoniu also understood and laughed: "My eldest nephew is so amazing, I'll try it too." After that, he rode the fire bull and rushed towards the stone worms.

At this time, Chen Wangping glanced at him and suddenly saw a faint system light coming from the insect corpse that had been scalded to death by the Fire Niucheng Formation.

"What else can I get after being so hot?"

He moved closer curiously, dragged the insect corpse back with pliers, flushed it, lowered the temperature, and then pulled it away. Finally, he found that the light of the system was coming out of a translucent stone the size of a fist.

"Stone? It looks familiar."

Chen Wangping curiously put it in the storage compartment and checked the attributes:

【Silica Silicon Ore】

【Usage: Smelting Materials】

[Special effect - Same race: Related devices created using insect silicon ore are less likely to be attacked by Zerg]

[Note: This is the essence of quartz worms, which will only be revealed in high temperatures]

When Chen Wangping just finished reading the attributes, he was a little unbelievable.

Silicone ore???

Can silicon ore be extracted from insects?

And it also has a self-protection special effect?

When he saw those insects invading before, he was a little worried about the damage to the equipment.

But now it seems that if it is made from Zerg materials, it is very likely to trigger the special effect of the same race and thus ensure the safety of the device.

Quartz worm?

This bug was really raining in time.

Chen Wangping is now worried that there is not enough silicon ore, but he didn't expect to be supplemented by the bugs!

"Fortunately, it was just released and rushed to the side of the Huo Niucheng Formation, otherwise there would be no high temperature and I would not be able to find this thing."

He turned to look at the countless quartz insects outside and rushed over impatiently.

I'm here for silicon mine!
