But

Something unexpected happened.

At the moment when the tortoise clan leader of knife and fork rushes into the crystal wall space.

Crystal wall space starts to tremble!

The original hard and solid crystal wall melted like candy. Starting from the outer crystal wall, it melts into a thick slurry and melts into the rock below.

"What's going on?" The tortoise clan leader stares at everything around him in surprise.

"This..."

Chu insect also looks strange!

In the data of the system, there is no ability to write crystal wall tree.

They have the ability to hide themselves from the rock wall, Chu Chong knows. He had seen the scene of rock wall melting before, but could the crystal wall tree melt itself? Where is the melting crystal wall hidden?

"Attack now!"

The head of the tortoise family ordered at once.

Because of the toxin corrosion in these two days, the God insect Legion has no spare power to attack the crystal wall tree. Now we can only rely on knife and fork, turtle and Lanling!

Blue spirit also joined in the attack, a cry, a water column attack to crystal wall tree.

The turtles waved their knives and forks at the crystal wall, but when chopping the crystal wall tree, they went straight across the crystal wall tree in the form of viscous liquid! The attack has been completely defused and has no effect.

Blue spirit's torrent attack is the same reason. Under the scouring, it even dilutes the dense liquid form of crystal wall tree. After dilution, it speeds up the return of thick liquid to the ground! do a seemingly clever thing which turns out to be a foolish one instead.

"Patriarch, it's no use!"

Knife and fork turtles are stupid.

Chu insect sighs: "everybody stop attacking, we should take crystal wall tree, have no way."

The sacred flame also reached the state of oil exhausted and lamp withered. The flame output lasted for two hours. Although the unit output was not as much as the previous flame storm, it also exhausted 90% of their flame power. Now every flame is flickering, as if it could be extinguished at any time. Some of the most vain flame can even see the red flame core inside!

Knife and fork turtles and blue spirit stopped attacking and watched crystal wall tree melt.

Chu insect is the most unwilling one, after all, crystal wall tree let it into such a big danger, but there is no way to revenge! This kind of feeling is very uncomfortable.

The front crystal wall has all melted and disappeared completely after melting into the ground rock! The turtles also tried to dig the ground, but there was nothing under the rock, as if it had really disappeared!

It's amazing.

Behind the crystal wall is also constantly melting, the wall thinning, behind a dark.

Finally, one part of the back crystal wall melted completely, and faults appeared in the upper and lower crystal walls.

The fault is a dark hole, and the wind is heard.

"Wait..." Chu insect's eyes slightly coagulate, "the wind?"

"I heard it, too!"

LAN Linglian said.

Chu insect just discovered at this time not right, the back of crystal wall tree shouldn't be rock wall? How can there be a dark hole?

"I'll go and have a look!" A knife and fork turtle can't bear it, so he has to go to check it.

"Wait!" There is a sacred fire in the family of sacred fire, "without light, even if you look in the past, you can't see anything. We should come! "

"You are very weak now. In case of any danger, you are likely to fall into an accident!" the head of daocha turtle frowned

Chu Chong smiles.

What are locusts used for?

This is the situation now. It's time for the scouts to show their skills!

"You don't have to fight."

A small team of locusts, only 100.

At the beginning of entering this space, Chu insect let the Scout locust quickly hide in the hill grass. The size of the Scouts is very small and the number is less, so they are not found by the crystal wall tree at all!

The scouting locust team flies out of the hill grass. The tortoises curiously look at the locusts with different postures.

The Scout locust had no other target. After forming a formation, he flew towards the dark hole.

The tortoises make way for the scouts.

Deng!

The scouts lit up.

There is a knife and fork tortoise who is frightened by the light. He adjusts his body posture in a hurry and feels very ashamed.

The scouts plunged into the cave.

There is a curious tortoise lying at the mouth of the cave to watch.

"It's a cave passage!" Cried the tortoise.

But before long, the scouts disappeared into the darkness. I can only see the faint light from afar.

After a long time.

Chu Chong received a message from the locust scouts.

Shocked.

"What's behind the cave?"

The animals asked."Yes..."

Chu insect did not say clearly: "you see with your own eyes to know!"

The animals are very curious.

What's behind the entrance?

The horde of insects is resting outside.

The sacred fire divided out dozens of companions, knife and fork turtle Lanling, and two blue Chu insects, and got into the cave together.

The lighting effect of the sacred fire is much better than that of the locust scouting.

As soon as you enter, the cave is lit up!

Chu Chong felt that he should always have a large number of Yang stone. Before, Chu Chong's Yang stone inventory was completely consumed in the fine and ordinary breeding fields. Yangshi is very convenient. It needs to be kept in stock.

The caves were boring at first, but the deeper they went, the wider they became.

The ground began to show some broken wood.

These wooden squares are obviously carefully cut.

Looking at these wooden squares, the beasts know that this place may be really unusual!

Continue to go inside, those broken wood gradually appeared complete. Some of them were tied together by the rope, and there were some dents on the ground that were polished off!

Chu Chong knew this, but the other animals were still at a loss about it. They guessed what these wooden squares were used for.

"These wooden squares should be weapons!" A knife and a fork.

"No, building materials!" The way of the sacred fire.

They argue with each other.

Chu Chong laughs: "all wrong! It's all wrong. "

"Ah?"

Both sides are somewhat unconvinced.

"You'll soon know what to do with it."

Hundreds of meters ahead.

Finally, a complete wooden square appeared! The wood is inlaid on the ground, showing only a small part. There is a rope between them.

"It's not a weapon!" The tortoise was a little depressed.

"It's not architecture, either!" The flame was also a little frustrated.

"But what is it? And all the way to the distance! " Cried the tortoise.

A sacred fire flew forward, looked at these strange wooden squares carefully, and suddenly exclaimed: "I know what this is! This is a ladder

"Where is the ladder inlaid on the ground?"

Chu insect ignored their argument and flew to the wood.

Touching mufang, Chu Chong sighs in his heart.

It's underground in the red stone belt

See the track!

Was it built by humans?

Some human kingdom?

The red stone belt has always been the site of wild animals. Does the human kingdom really have the ability to build such complex tracks in the depths of the red stone belt, which is extremely close to the central district?

If it wasn't for the human kingdom

Is it a group of wild animals in the jungle?

Chu Chong can't imagine!

This intricate underground track completely subverts Chu Chong's cognition!
