Tan Chu held the fire spirit dragon candle, Princess Qinglin brandished a pickaxe, followed by the Night Sisters and the Moon Dragon Phoenix Spirit, and at the end was a big blood bag...

Heijiao and the two Pegasi guarded the entrance to the cave at the foot of the mountain, and everyone was now waiting, what kind of secret passage could Qinglin's little girl dig out to bring them to the barracks on the top of the mountain?

"Boss, if we continue to dig like this, won't we have another secret passage like the one in the beast camp?" The big blood bag just remembered...

"Da Baozi is right, we have no other way but to pin our hopes on this secret passage." Tan Chu nodded.

"Understood, as long as the secret passage is dug, we can take this barracks!" Big Blood Pack said excitedly.

"Yes, as long as we own this military camp, in fact, the entire Godfall Land will be completely controlled by us." Tan Chu said with a smile.

In the air just now, he had already seen a large map of the Godfall Land, and among the cobweb-like canyons and ravines, only the peak where the Rock Barracks was located was the most peculiar...

Not only is it the highest altitude, but it is also the final meeting place of all the canyons and ravines.

In other words, there are several canyons below the peaks of the Rock Barracks, and it is easy to get to any of the labyrinthine canyons...

Moreover, the Rock Barracks guards the place where the gourd mouth must pass, and firmly guards the teleportation array leading to the Evil Plain!

As long as you have this rock barracks, it is equivalent to controlling the entire Godfall Land within the surveillance range of the barracks, and as long as you find an enemy, you can send a legion from the barracks to intercept it at any time...

If you can fight it, you can fight, but if you can't beat it, you can also use the ravine terrain to intercept it, and if you can't do it, you can shrink back to the top of the mountain, and no one can launch a strong attack.

Tan Chu chatted with his teammates, waiting for Princess Qinglin to dig the cave quickly, and before they knew it, the group had already advanced hundreds of meters up the curved cave...

Bite...

After a crisp sound, Princess Qinglin stopped her excavation work and turned to look at Tan Chu...

"Little brother, we should have reached the top of the mountain." Princess Qinglin said.

"Ahh So fast, huh? The crowd was amazed.

Because they only cared about chatting, they didn't care about the progress of the excavation, they just followed Qinglin all the way forward, and soon more than two hours had passed.

Since it was Princess Qinglin digging the cave alone, everyone couldn't bear to urge it, so they didn't pay attention to the situation at all...

Unexpectedly, the little girl actually told them that the cave had been dug under the barracks!

"Qinglin, you're not lying to me being happy, are you?" Tan Chu asked with a smile.

"No, little brother, what do you think this is?" Princess Qinglin picked up a prop from the stone steps and handed it to him...

This is...

A broken brick!

Looking at the half of the green brick in Princess Qinglin's hand, Tan Chu's heart was excited...

It is only possible to find such building materials near buildings...

In other words, their position at this time has actually come to the bottom of the rock barracks!

"Wait, I'll look at the map first." Tan Chu's eyes lit up, and he immediately called out the map system to check the current coordinates...

I saw that on a pitch-black map, the long snake-like hole was crooked, and everyone's small green dots were particularly shining in the pitch-black environment.

Tan Chu immediately found the cursor that belonged to him and noted down the coordinates and location...

１０１．１２．－３！

When he saw this string of coordinate numbers, he had fully understood that they were only three meters away from the map of the Rock Barracks...

The coordinates of the system do not lie, and the number -3 must mean that they are now three meters underground.

"Sister Qinglin, since you have dug under the barracks, let's just dig it out." Nightfall laughed.

"Don't, we don't know what the situation is in the barracks outside, if the place we dig through is on the square of the Dark Legion, then we will die!" Tan Chu hurriedly said.

"Uh-huh, I see." Princess Qinglin nodded.

"I'll go, and this kind of trouble... But how do we know where the exit is? Nightfall said in surprise.

"It's very simple, let's not rush to dig through the passage, go out and see the coordinates of the big map, it's easy to find the approximate location of the secret passage." Tan Chu said.

"Brother Beast is amazing." Nightmoon said with a smile.

"I have a military map, so the little tiger doesn't have to be so troublesome." Feng Ling said suddenly.

"Military maps... Take a look. Tan Chu said in surprise.

The so-called military map is actually the kind of three-dimensional map like a sand table model...

This kind of sand table three-dimensional map is a powerful command function that only generals in the barracks can enjoy, but unfortunately there is a limitation.

That is, the exploration degree of this map must meet certain requirements in order to open the sand table drill function of this map...

Swish!

Feng Ling waved his hand, a faint golden light flickered, and a three-dimensional map appeared in the cave....

"I'm going to see a thumbnail of the Rock Barracks." Tan Chu said.

"Understood." Feng Ling nodded, and with a wave of his jade hand, the map quickly changed...

A detailed map in the shape of a mountain peak appeared in front of Tan Chu and the players.

"Little Tiger, what information you need, just point your finger up and you can see it." Feng Ling explained.

"Okay." Tan Chu nodded and walked to the virtual peak...

With a flick of a finger, the mountain range became larger, and a magnificent military camp appeared on it, and around the barracks, and even in all corners of the hillside, there were countless checkpoints and arrow towers...

It can be said that when the elves built this military camp, they had already taken into account the attacks from the sky and the ground, and made the defense watertight.

Even under the ground, it seems that they have long been prepared ...

The situation of the entire Rock Barracks is now completely in front of Tan Chu's eyes, no matter what the information is, he can see it clearly...

He mobilized the three-dimensional map, and was surprised to find that the underground coordinates where everyone was located were in the general's line in the center of the barracks!

And between the foundation of the entire barracks and three meters underground, there is a thick red line marked, I don't know what it means...

"Ahh And this thing, thankfully I didn't dig it hastily. Princess Qinglin looked at this three-dimensional picture from the side, and couldn't help but exclaim.

"What's wrong, is there something wrong with this thick line?" Tan Chu asked puzzled.

"Uncle Tie Ding said that any well-defended building must be taken into account in the sky and on the ground, there is air defense in the sky, there are high walls on the ground, and there are protective seals in the ground... This thick red line is a seal to prevent the enemy from attacking from below the ground, and once touched, the entire barracks will issue a warning and inform the barracks guards of the location of our hole. Princess Qinglin said.

Looking at her appearance, it seems that she has been learning from Master Tie Ding during this time, and she is so proficient in the construction industry...

Protect the seal!

Hearing this name, Tan Chu felt a little headache, this would be another big trouble...
