This time he visited the evil clan camp again, and Tan Chu came for the mission.

Now that the safety of Shadow City can be ensured, he is now thinking about completing the mission of [Return of the King].

If he waited for the Dwarves to rescue the Iron King on their own, his mission would have been declared a failure, with no loss, but no reward would have been obtained.

This is definitely not good news for Tan Chu.

For the sake of high rewards and other important tasks that may have already appeared, Tan Chu endured his fatigue and came to this military camp again with a large blood bag.

At this time, the two of them had come to the center of the barracks after a cautious and rapid walk.

They are only a street away from the demon generals, and they are only a building away...

The footsteps outside gradually stopped, and Tan Chuzhi said that the opportunity had come.

"Let's go." Tan Chu said in a low voice.

He immediately went around the back of the building with a large blood bag and rushed down the eaves towards the peak...

Outside was a large central square, where there should have been a place full of evil soldiers, but now it was empty and there was not a single figure in sight.

Tan Chu knew in his heart that the ambush of the evil clan was attacked by the dark army, and at this time, the whole army was setting off to attack these daring guys in the swamp area...

However, this happened to fall into his predetermined plan, and the emptiness of the barracks was so empty that it gave him and Da Xuebao a once-in-a-lifetime opportunity to get close to the key position of the barracks.

The two black-robed figures moved quickly and ghostly, quickly rushing through the central square and flashing into a large black building complex.

It wasn't until the two of them got back into the back of a building that Tan Chu was about to jump to the heart of his throat that he returned to his original position.

"Boss, it's exciting." Big Blood Bag said with a smile.

"Where was the last time you were held?" Tan Chu asked.

"It's in the row of barracks behind the general's line, and it seems to be all the resting area for the ghost priests." The big blood bag pointed behind the general's line and said.

"Uh... So you don't see nothing? Tan Chu asked with a smile.

"Yes, the last time I was detained, there were all soldiers outside, and I was scared to death, where did I dare to go out to find out the environment." The big blood bag nodded.

"Forget it, our target this time is below the mountain peak, you watch out for that evil clan sentry on the mountainside." Tan Chu advised.

It was not easy to get here, and the most dangerous thing now is that if the two of them continue to move forward, they will definitely enter the surveillance range of that evil clan's secret sentinel!

As long as they are not careful, the hard work of the two will be in vain, not to mention, and they will leave their lives here...

"Boss, I see, the surveillance area of that dark sentry is very large, and the entire area of hundreds of meters in front of the mountain peak is under its watch." The big blood bag looked at the mountain peak in the distance in surprise, and soon found the small platform halfway up the mountain...

Above the small platform, there was a black mass of stuff, which immediately surprised the big blood pack.

They had all seen the power of this thing, and once it was discovered, the entire military camp would be boiling!

"Be careful for a moment, and try not to let it see us." Tan Chu advised.

The two of them immediately hid behind one building after another, bypassing a few patrolling evil soldiers, and quickly headed towards the mountain peak...

After another twenty minutes of cautious progress, the two finally came to the back row of barracks behind the wall, but the situation in front of them made them dumbfounded at the same time...

In front of the peak, there was a large open space, without any buildings on it, and it seemed that the open land was specially arranged by the evil clan in this way, just to prevent any enemies from sneaking here.

Tan Chu looked at the environment in front of him blankly, and saw that under the tall mountain peaks in the distance, there seemed to be a thick iron door...

It's already certain that this is where the Dwarven King is being held!

But where did the dwarven rescuers go?

He and the big blood bag had already arrived here, but they couldn't see the rescue team of the dwarves who had come to rescue their king...

Could it be that these guys were killed by the evil clan long before they arrived?

Tan Chu was surprised in his heart, because his mission had not yet failed, which meant that the dwarves had not yet rescued the Iron Battle King...

In other words, the dwarves' rescue mission has not yet begun, or has failed!

"Boss, how are we going to get there, there's a big open space here, there is no shelter, we will be found as soon as we get out." Big Blood Pack whispered in surprise.

"Don't worry, wait until I figure it out." Tan Chu hid behind the wall in a daze, and his brain began to spin rapidly...

Looking at the terrain in front of you, there is no environment to use here, and if you want to get close to the secret fortress under the peak, you must force your way through...

Under the watchful eye of that mysterious sentry on the mountainside, any stealth is ineffective, unless...

Unless digging tunnels!

Belch...

Tan Chu was happy in his heart, he knew why he hadn't seen the rescue team of the dwarf clan, maybe these dwarves were digging tunnels under his feet!

"Big buns, the two of us will separate and look around the neighborhood to see if there is anything special." Tan Chu said with a smile.

"Where are you looking, boss, I don't know." Big Blood Pack asked in surprise.

"Look for places that might be entrances to the tunnels, where the dwarves may be digging tunnels." Tan Chu said with a smile.

"I see, it's still the boss." The big blood bag nodded.

The two of them immediately scattered towards the barracks, following the walls of one building after another, carefully searching for the special environment here...

Fortunately, most of the evil legions had left the barracks, and the military tents here were empty, creating convenient conditions for their operations.

Tan Chu to the left, the big blood bag to the right, the two quickly dispersed, and searched everywhere in this complex...

The rows of buildings were carefully inspected by the two of them, and they were selected one by one...

But more than ten minutes have passed, and the two are already dozens of meters apart, but they still have nothing to find ...

"Boss, I can't find a special place." The big blood bag refound Tan Chu's location, and the two met again.

"What a headache, where are the dwarfs?" Tan Chu said speechlessly.

The entire map of the building area near the mountain peak has been checked by the two of them, but the entrance to the tunnel that Tan Chu guessed has still not been found.

"Boss, if there are dwarfs digging tunnels here, the ground will definitely be heard." Said the big blood pack.

"Good idea, I didn't think of it." Tan Chu was reminded by him, and immediately said in surprise.

He immediately leaned down and pressed his ear to the ground, listening to the movement coming from underground...

Clang... Clang...

Sure enough, when his ears were close to the ground and he was paying close attention to the situation underground, a slight metal knock sound immediately appeared in his ears...

"Boss, I hear a voice!" Big Blood Pack said excitedly.

"I heard it too, it seems that the sound is still far away, and we follow the source of the sound to find it." Tan Chu said happily.

Poor dwarves, they must have dug tunnels here all night...
