"Boss, are you sure this passage can go directly behind the Demon Fortress?"

The front waist of Manniu Bow asked while walking in the passage full of hanging stone pillars.

It took them several hours to get into a mountain range to the left of the black wasteland, and then they drilled into the mountain and found a cave hidden by branches at the foot of a certain mountain.

This cave is not an underground passage they have seen before, but a small cave about two meters leads directly to the ground. The cave is covered with stone pillars as sharp as teeth and extends from the top or bottom, and if you are accidentally touched, your clothes will be scratched.

To be honest, if they hadn't cut off several stone pillars with their swords, they would have thought they had come into the body of a monster.

It is very inconvenient to move here because you will accidentally hit a sharp stone pillar. If the force is too strong, it will easily scratch.

But there was no way. The place they walked above was already very close to the Demon Fortress. Even if they were invisible all the way, they could not guarantee safety. From time to time, they encountered the patrol teams of the Demon Fortress, all equipped with demon hunting dogs. The demon's nose was very spiritual and it was easy to find their traces.

The strength of the Demon Fortress is beyond their imagination. Every patrol team outside has hundreds of demons. The leader must be the small boss of the leader's template. They will not only kill them for a while, but will soon attract other demon teams. After trying twice, he simply gave up and crawled the hole here honestly.

Fortunately, it is difficult for them to leave this cave and the demons to leave. There are no monsters inside. Only a small number of insects that have been eroded by the demonic aura are easily killed by them.

After walking through the cave for a long time, the terrain began to rise and fall, and continued to rise and fall. It also sneaked through a flooded passage, and finally arrived at the destination, under the cliff behind the Demon Fortress.

The passage came out from under the cliff, pushed open the stone blocking the hole, and a group of four people came out.

“It’s so corrupted here!”

At first glance, the stones and trees under the cliff were all black, and the ground was emitting a hint of black air. The entire stone wall was black, and there was a vague tingling feeling when pressed on it.

Obviously, influenced by the demons that were calculated by the demon fortress of 100,000, this place has been completely corrupted, even if the growing trees have been demonized as soon as they were born.

There is no demon patrol team here, which is probably a misunderstanding of ordinary people. At most, there are guards on the cliff, and there are no patrol teams under the cliff, which is convenient for them.

Ye Qing gathered the team members together and said:

"Let An Mie go up to check the situation on the edge of the cliff, and then find a dead corner for me to go up. This time we will first touch the situation in the fortress, not the battle, so Manniu, you and Xiaoyu are waiting below."

The two of them didn't say anything, even Manniu was the same, obviously knowing that it was too dangerous to the top.

After a brief discussion, he blessed a flying technique and light body technique to the dark destruction, and asked him to go up first.

The flight technique allows him to fly up, and the light body technique allows him to climb easily against the stone wall, so as not to consume too much effort.

When An Mie's figure disappeared, he pulled the two of them and hid in the cave that had crawled out before, so as not to see the demons above.

After waiting for almost an hour, the team channel received a response from Animi. Ye Qing came out of the cave, gave the two of them a reassuring gesture, and soared into the air and rose up.

Through positioning in the team channel, Ye Qing flew to the left for nearly one kilometer, and then slowly rose up. The safety blind spot found by the Animi was here.

Just as he climbed up the cliff, the Demon Fortress welcomed a patrol team of demons back to the fortress, but no one noticed it. One of the dark hunters in this demon team looked strange, and kept looking around, but the amplitude was very small. In addition, his appearance was a pure demon image, no other demons noticed it.

After returning to the barracks, the demon left the team and began to wander around.

"This place is good, and there are usually no demons coming."

Ye Qing squatted in the gap behind several piles of huge rocks on the edge of the cliff. This was the safe place for An Mie to find. There were stones on one side of the cliff. As long as there was no movement, there would never be any demons to observe.

After taking a break, he blessed himself with a light body technique and an invisibility technique, and touched it out one after another.

Needless to say, the invisibility technique is to reduce footprints. He is not as good at stealth like the dark migratory. If he does not have the light body technique, his foot technique will easily leave subtle sounds and be discovered.

Most of the demons guarding are dark hunters. Little demons like the Destroyed Demon are too active and like to make noise, so they are not suitable for guarding. Most of the time they are used as cannon fodder.

Of course, it is not completely gone. Ye Qing saw a group of destructive demons surrounding him and wondering what he was doing.

Demons also have their own social composition. Although they spend most of their time killing, they still have their own social composition. Even the lowest-level destruction is the same. Their biggest hobby is not to cook broth together, but to fight.

That's right, the demon is aggressive by nature, and even if there is no enemy, there are often conflicts within it. At this time, fights are needed to resolve it.

The group of Shen Lun in front of him surrounded him, holding a mace in his hand and constantly smashing on the ground and making strange screams. The two ends of the destruction who were stronger than their kind were fighting together.

They did not fight with bare hands, but instead swung the maces with sharp spikes to greet the opponent. The two destructive demons were already covered with holes, and the demons were bleeding all over, one of them was almost open, and a hole was poked out by the mace, and some strange liquid flowed out of it.

The two of them bypassed the group of fanatical and lively destruction and did not attract attention, climbing up the ridge along the side.

From here you can see the full picture of the Demon Fortress. The Demon Fortress is built at the junction of the Black Wasteland and the Taimo Heights. The entire fortress leans on the suddenly raised high ground and is divided into two parts. One is still in the Black Wasteland and the other is on the Taimo Heights, with a huge gap.

The lower part is a huge military camp, with rough demon buildings connected for more than ten kilometers. Ye Qing is now on the edge of the Taimo Heights. From above, you can see the dense figures of demons in the military camp. It is difficult to estimate the specific number, but it is certain that the total number exceeds 100,000.

The architectural style of the upper part is relatively refined. High towers with black smoke leaps into the sky, just like volcanoes. A large amount of black smoke gathers together to form a thick layer of black clouds to cover the entire fortress. From time to time, black figures are seen hovering between the smoke pillars, but it is not a stinking crow because the distance is too far away.

There are probably some identity demons living on the Demon Fortress, such as some small bosses, and Bisubo is sure to be inside.

The two of them looked for a while and asked:

"How do we get close?"

He rubbed his chin with his fingers, but he didn't answer for a moment.

There are so many demons that there are no blind spots without special guarding. The huge number of demons that flows all the time can protect the entire fortress. It is harder to touch it than climbing the sky.

But even if it is more difficult than climbing the sky, they have to find a way to complete this task, and it is not impossible.

It's still the old way, digging a hole.

That's right, you can't touch it from the front, and you can't fly in from the sky. You can only use strange tricks to dig it from the ground with fossils into mud.

He told An Mie how to tell An Mie that An Mie had no objection, and this was the only way.

He started doing it as soon as he said that, and he immediately turned around and returned to the edge of the cliff and jumped down. Anmi left on it. He wanted to dig from the closest place to the fortress Bishuboshu's residence. Anmi left on it to position him so that he would faint if he dig the wrong place.

After flying down again, he found Manniu and Mi Xiaoyu. This time they both had to help. Manniu was responsible for doing the coolies and Mi Xiaoyu was responsible for keeping watch.

The place they chose was a cliff. There was no demon patrol above it, but a dead corner. It was impossible to climb up from here normally. Mi Xiaoyu found a place not far from the stone wall to hide and keep watch. Ye Qing and Man Niu lay on the edge of the stone wall, stretched out his palm, and there was a layer of inspiration surrounding it.

When the palm of your hand was pressed on the stone wall, the light of inspiration spreads on the stone wall, and the hard stone immediately began to soften, like wet soil, and you could take out a large piece of it with just one slightest bit.

The softness and hardness of the fossils that are formed into mud can be controlled. They can be directly transformed to the softest and can be dug out with the smallest force.

Manniu took out a white board and his hands were sank into the handle. He held the hilt in his hand and stirred it in the mud. He dug out a large piece of soft mud, and then dug out a large pit with a diameter of more than one meter in a few strokes.

A few times dug out a cave that was nearly three meters long, Ye Qing walked to the end of the cave, stretched out his hand again, turning the hard stone inside into soft mud again, and exited for Manniu to continue digging.

While digging forward, he recalled the terrain he had seen before, dug into the fortress based on his memory, and occasionally redirected the direction with the hidden dark destruction hidden above to avoid digging wrongly.

With this stupid method, it took almost three hours to dig a hole that was almost a kilometer long, which was a miracle.

After digging here, you have basically entered the fortress. If you dig up from here, you can enter the upper part of the fortress.

But Ye Qing was not satisfied. This place was just the outer periphery of the fortress, and it was still far from where Bisubos was located, so it would take at least half a day to dig.

Fortunately, they have enough time and will not be discovered by demons here, and it is even more impossible for the demons to hear the movement. The hard stone turns into soft mud, and there will be no big movement. Unless they are dug under their feet, it is impossible to discover it.

The two of them took a break and continued to dig forward, preparing to dig to the destination in one breath.

Just as they were in this local rat, a roar suddenly came from above the monastery deep in the Taimo Heights:
Chapter completed!
