After about a minute, Chen Fei heard the sound of battle coming from the depths of the passage, and it seemed that under the leadership of Xiao Qiang, they had successfully caught up with the worm mother.

Chen Fei refocused his gaze on the body of the insect mother that the flame was gradually extinguishing, although Chen Fei explained in his mouth, but with Nangong Jin and Wang Yuanyuan's understanding of Chen Fei, when Chen Fei showed such a serious expression, it proved that he had something more important to do, or something important to discover.

When the huge body of the insect mother was burned to only a section of black charcoal, Chen Fei couldn't wait to burrow into the narrow passage, fiddling with the M9 multi-function bayonet in his hand to find something, his expression was serious and careful.

"Sister Jin, what is Brother Chen looking for? Could it be that there is something in the body of the worm mother? ”

Wang Yuanyuan asked Nangong Jin beside him with a curious expression, but Nangong Jin shook his head, obviously he didn't know what Chen Fei was going to do.

"For Chen Fei to rummage so carefully, it must be something important, we will wait quietly here, and we will know the answer in a while."

Mu Meiqing sat directly on the ground after speaking, Nangong Jin and Wang Yuanyuan simply sat beside her when they saw this, and the three of them looked at the back of the same man together, with a faint smile on the corner of their mouths.

Chen Fei was concentrating on looking for the insect stone that the system said, but what made him feel extremely painful was that he only knew that the thing he was looking for was called the insect stone, and the black and black black was not inconspicuous at all, and Chen Fei didn't know anything about anything else, and he didn't even know how big the specific insect stone was.

"Damn! Why can't I find anything? Is there something wrong with the system? Or was the stone also burned to ashes? ”

Chen Fei shook his head again and again, muttering quietly in his mouth.

Wow......

The blade of the M9 multi-function bayonet in his hand seemed to have touched something hard, and there was a crisp sound!

Chen Fei raised his eyebrows and subconsciously lowered his head a lot, rummaging carefully through the pile of ashes, and soon an irregular stone the size of a baby's fist appeared in his sight.

This is the worm stone???

Chen Fei looked at this stone like a black coal, his face was speechless, this thing was thrown on the ground, it is estimated that no one wants to take a look at this thing and it will be kicked away, and he doesn't even bother to kick it.

However, it was such an ordinary black stone that could be said to be rare by the system, and it was even almost highlighted to warn Chen Fei that he had to collect it.

Chen Fei tugged at the corners of his mouth, and he didn't forget to complain in his mouth:

"Damn! If it's ugly, it's ugly, since the system dad said that your broken stone is rare, you look like a lump of cow dung, so I have to put it away. ”

Chen Fei said as he reached out and grabbed the black stone, after the palm of his hand touched, Chen Fei could still feel a trace of warmth from the stone, which should have absorbed some of the heat from the burning body of the insect mother.

Well???

When Chen Fei held the black stone in his hand, he couldn't help but let out a sound of surprise.

This black stone is no bigger than a baby's fist, but it has a weight that does not match its volume, if not ten catties, it is about eight or nine catties.

This shows that this inconspicuous black stone has a very high density!

In addition to this, Chen Fei also found that when the headlamp above his head shone on the black stone in his hand, the surrounding light seemed to be much darker, as if the light source was absorbed by the black stone in his hand.

"Tut-tut..... It's a bit interesting.,It's worthy of being stamped with a rare label by the system.,Just put it away without saying anything.,And the more the better! ”

“......”

After knowing the extraordinaryness of this stone, Chen Fei suddenly became full of energy, although this kind of good thing that was favored by the system has no use for him for the time being, but it will definitely have a vital role in the future, and at that time Chen Fei will secretly rejoice because of the decision made today.

After discovering the first insect stone, Chen Fei found seventeen insect stones one after another, all of which were the size of a baby's fist, but fortunately, the number was still in the past.

Chen Fei speculated that there might still be this kind of black insect stone in the half of the body of the insect mother who escaped, if it was an evolutionary crystal, it would definitely not be his turn to take it, but these inconspicuous stones, I believe that only he who has a system knows the value of this thing.

After Chen Fei put all these insect stones into the storage space, he walked out of the passage with a happy face.

Looking at Chen Fei's smiling expression, Nangong Jin quipped on the side:

"Chen Fei, when I look at your expression, why does it feel like you've picked up some good treasure? The laughter is still a little lewd! ”

Chen Fei looked at Nangong Jin's appearance, and replied with a mysterious smile:

"Sister Jin, you really guessed right this time, I did find something good! I'm here to give you long eyes! ”

Chen Fei said and took out a worm stone from the storage space and showed it to the three girls, originally when they saw Chen Fei's pretended mysterious expression, the three girls still had a little bit of expectation in their hearts, but when they saw Chen Fei take out a stone like a coal, the three girls had the same speechless expression on their faces.

Nan Attack frowned, glared at Chen Fei hard, and asked:

"This is the treasure you found?"

Facing the questioning gaze of the three women, Chen Fei was also innocent and speechless, and he didn't blame them for having this kind of thought, after all, he also had this idea just a few minutes ago.

Forehead.......

Chen Fei didn't know how to explain it for a while.

He simply put the insect stone in his hand in Nangong Jin's hand, and the moment the black stone was started, Nangong Jin noticed that it was different, because he was defenseless and underestimated the weight of this stone, which made Nangong Jin almost drop the stone in his hand to the ground.

Nangong Jin snorted lightly and passed this stone to Mu Meiqing and Wang Yuanyuan, so that they could also feel it carefully, but their change in their perception of this stone was only that it was much heavier than ordinary stones, nothing more.......

Chen Fei was dumbfounded by the third girl, because he really didn't know how to explain how rare this stone was, and for the time being, this insect stone really had no practical value.

"Let's go over and see how the battle is going over there."

Chen Fei could only laugh dryly and forcibly divert the topic.

Seeing Chen Fei's appearance of turning around, the three girls all had smiles on their faces.

After winding along the wide passage dug by Xiao Qiang for a distance of about a hundred meters, Chen Fei and the others entered a huge space, which was not dug out by Xiao Qiang and the insect mother, but more like a natural formation.

At this time, a red insect of five or six meters was constantly struggling and rolling in the flames, and the flames burned its body and made a sizzling sound, mixed with a squeaky sound.

And Rahu and his party surrounded the insect mother in the center, and the current situation has been completely controlled by them.

After seeing this situation, Chen Fei began to carefully look at the situation of this underground space, which was the size of a basketball court, densely packed with holes of various sizes like honeycomb coal.

From time to time, zombie bugs of different sizes will flood here, and they will frantically pounce on the mother worm, but they will only become fuel for the flames.

The mother tried her best to break free from the flames' grasp, but due to its weakening strength, it no longer had any ability to resist escape.

knows the cunning of the insect mother, and even if the insect mother has already planted her wings and is difficult to fly, the people present have not slackened in the slightest.

Chen Fei looked in the cave, and soon he found a pile of stones the size of a baby's fist like coals in the corner, piled up there so randomly, Chen Fei roughly estimated that these must have exceeded a hundred.

System: A large number of insect stones are detected, a large number of insect stones are detected, and it is recommended to give priority to collecting insect stones.

Although the voice of the system did not fluctuate in tone, Chen Fei knew in his heart that the system seemed to be more anxious than him.

Zhang Yan and Luo Hu controlled the flames of the continuous cauterization of the insect mother, and in the face of the threat of death, the insect mother tried her best to secrete the fireproof liquid, and when the battle was nearing the end, it completely turned into an endurance tug-of-war.

The body of the mother worm keeps splitting its body in the flames, trying to escape in this way, from a long line of six or seven meters, to less than one meter in the end, the appearance of the mother worm is not much different from the average zombie insect, if it is mixed into the swarm of zombie insects, and then trying to find it is tantamount to looking for a needle in a haystack.
