"Island Master, the shells of these undead beetles are too hard!" Jiang Yuntian also saw that the bullet hit the undead beetle and was instantly bounced off.

Xiao Yi also frowned. When he and the giants killed the undead beetles just now, he didn't feel that the shell of these beetles would be so hard.

"The undead beetle's skill, armor and shield, can enhance your defense after being activated, lasting for 20 seconds."

After seeing the prompt of the system, Xiao Yi suddenly said, "no wonder these beetles have become so hard."

Jiang Yuntian asked curiously, "what's going on?"

"Because these beetles have opened their skills and increased their own defense, we can solve them if we stick to them for 20 seconds!" Xiao Yi replied with a smile.

Now the weapons in the hands of soldiers are SS level after all. It's not impossible to break through the defense of undead beetles!

Before Xiao Yi's voice fell, the front-line soldiers suddenly found that the shell of the undead beetle that could have blocked bullets was suddenly broken!

Those undead beetles rushed to the position of more than ten meters in front of the defense line arranged by Jiang Yuntian, and became crispy as if they had changed their equipment.

Dada, dada!

The barrage tore up the undead beetles and turned them into pieces of meat on the ground.

The soldiers of the yiranpin alliance laughed.

"I thought how hard it was, that's it?"

"Yes, I thought I would use a grenade directly!"

"Yes, I also thought it was necessary to use grenades to deal with so many undead beetles with hard shells!"

Jiang Yuntian conveyed Xiao Yi's message to the front: "don't be careless. This undead beetle has its own skill. It can make its shell very hard. The duration of this skill is 20 seconds. As long as we stick to these 20 seconds, we can easily kill them!"

"No wonder these big beetles still have skills!"

"Then we may be in trouble. If there are commanders, they can easily break through the defense composed of our guns!"

"That's right, but our alliance doesn't just have guns!" A soldier raised his grenade and said with a smile.

"Well, so I just remind you not to be careless!" A team leader said.

"Yes!" The crowd responded.

It seems that the conversation of these soldiers was heard by a commander of the undead. Those undead beetles really began to use their skills regularly!

After the undead beetle in front uses the armor shield, the beetle in the back rushes forward frantically. After the undead beetle in front dies, the beetle in the back will immediately activate the armor shield and continue to move forward.

In this way, the undead beetles soon approached Jiang Yuntian's defense line again.

"Lying grass, did the undead hear what you said, or are you the commander of the undead?"

"I just said such a possibility. Who knows, they really did what I said!"

"You crow mouth, don't talk in the future. Everyone throw grenades immediately and be sure to block them!"

"Yes!" The crowd answered.

Whoosh!

Grenades flew out of the defensive positions and landed in the undead beetles.

Boom, boom!

The original extremely hard armor shield was torn by the power of grenade explosion in an instant.

"It seems that it still needs a large amount of gunpowder!" After Xiao Yi killed the undead beetle near, he muttered after watching the results of the grenade explosion.

At this time, the teams digging mountains were also taken care of by the immortal beetles.

Xiao Yi and giant can only constantly protect those staff!

Fortunately, most of the machines brought by Anyue are automatic machines, which do not require too much labor, so there are few staff, and the energy spar mined by the automatic mining machine will be immediately traded back to the Yiran alliance.

When Anyue came, he brought an island monument that was transferred to the car, so he can trade these energy crystals back at any time.

"Island owner, those mining equipment that need manual labor can hardly work. Let's trade them all back!" Anyue shouted, "these 30 automatic mining machines alone should be able to complete it!"

Because the purity of the energy spar on the ananeng mountain is very high, and it is very hit, these mining machines only need to cut the energy spar, and they don't need much operation at all.

This kind of operation is just cutting. It is not too simple for the full-automatic intelligent mining machine, and the efficiency is very high.

Xiao Yi nodded and replied, "OK, trade all the other mining equipment back!"

"Yes!" Anyue immediately operated on the island monument.

Soon all the equipment was traded back, and all the operators used huichengshi and left here.

Automatic intelligent mining machines are SSS level equipment, and these SS Level immortal beetles are difficult to harm them.

Of course, too many undead beetles will certainly affect their work efficiency.

In this way, Xiao Yi and the giants now have much simpler things. They only need to kill the undead beetles in front of those mining machines!

Because there are only 30 fully automatic mining machines, the giant has also freed up a lot of people to help the surrounding defense line.

With the participation of giants, there is no pressure on the defense line!

The undead beetles originally wanted to break through the defense line of the easy natural products alliance and stop the mining machines from mining the energy spar.

But now it seems that we can't stop the action of yiranpin alliance at all!

For a moment, the undead beetles all over the mountains suddenly began to drill underground.

Xiao Yi and others could only seize the time to kill several more, and then they could only watch them get into the ground.

"What a pity. We killed 30% at most." Jiang Yuntian said with some pity.

Xiao Yi shook his head, looked at the caves on the ground and said, "we only killed 10% at most. There are too many undead beetles, and a very small part may come out!"

Jiang Yuntian was stunned, then frowned and said, "if this kind of thing invades the survivor's Island, it is estimated that it will be very troublesome!"

Xiao Yi also frowned. Indeed, the main reason is that the undead beetle can drill into the ground, which makes people very helpless!

As long as they get underground, with the current weapons and technology, it is difficult to solve this underground creature!

"Yes, it seems that we still need to find a way to deal with this kind of creature that can drill into the earth!" Xiao Yi agreed.

Jiang Yuntian suddenly said, "if we can find out the medicine to kill cockroaches and other insects in the previous world, will it be much easier to deal with them?"

Xiao Yi shook his head and replied, "not necessarily. The undead creatures are not ordinary creatures. Whether those chemicals can work or not is not certain."
