In the tunnel where the four of them were, nothing fell down.

But Mu's expression became solemn, and he shouted without looking back: "Rod, pick a door quickly, I can't hold on for long!"

"What's the situation?" Gu Qingshan asked.

"The things above are too heavy, and even the holy pillars cannot support them!" Mu said.

——Too heavy?

Gu Qingshan looked over.

I saw that on the stone pillar that the curtain took out, thin cracks were spreading rapidly.

It really can't hold on for too long!

Gu Qingshan withdrew his gaze, swept through the doors quickly, and finally selected a target.

He pointed to a door and whispered:

"Everyone comes over, let's go into this door!"

The three teenagers looked in the direction he pointed.

I saw a line of prompts written in a fairy text on the door:

"Kind tips:"

"This door leads to the ground. Friends who want to go to the ground to get some breath, please go to this door."

Chihu looked at the prompt and hesitated: "Enter this door? But it says it leads to the ground!"

Gu Qingshan, Mu, Renadol said in unison: "It must not be the ground!"

Gu Qingshan pushed open the door and saw a long passage inside.

He waved to everyone and said, "Come on—"

Everyone entered in a row.

Gu Qingshan released the black dog and said, "The situation is critical. Go and explore the way immediately. We will wait for your news."

"Wang!"

The black dog responded, turned into a ball of afterimage, and ran towards the end of the passage.

Gu Qingshan was guarding the door and waiting quietly.

"My Holy Pillar can't support it anymore." Mu frowned.

Everyone looked at it.

I saw the stone pillar standing in the middle of the tunnel, covered with cracks and collapsed almost at any time.

"Persevere for the last time." Gu Qingshan said.

One breath.

Two breaths.

A ball of black fire suddenly appeared in front of everyone and condensed into a black dog again.

"This is a passage leading to the underground, unfathomable!" said the black dog.

Everyone felt a little relieved.

——Since it leads to the underground, everyone can temporarily avoid threats from the ground.

“Beautiful job!”

Gu Qingshan praised, handed the black dog a bottle of wine, and then said to the mu: "Come back the stone pillar."

The mute immediately closed the stone pillar.

"Let's go?" Renidol asked.

"You guys go first, I'll take a look at what it is, can--" Gu Qingshan said.

boom!!!

A huge roar sounded from afar, and everyone saw Gu Qingshan's mouth move a few times, but they could not hear what he said at all.

The tunnel has entered a stage of complete collapse.

Dust is made, countless stone bricks fall down, followed by the walls—

The walls also seemed to have been greatly impacted and are gradually collapsing.

The doors on the walls were crushed one after another.

"It's too late to go!" Mu pulled Gu Qingshan and shouted loudly.

Gu Qingshan reached out and made a move outside.

Something went through the falling bricks and stones and fell into his hands.

"Let's go!"

Gu Qingshan closed the door.
Chapter completed!
