Su Chen turned around and looked at everyone calmly.

In the past, he would never dare to make secret passages and enter the demon cave from the secret passages. Once he was discovered by the monks of the Demon Evil Alliance and surrounded it, it would be troublesome. If he encounters the evil Jindan cultivator, it would be even more unlucky, and he might not even be able to escape.

But now, dozens of Jindan monks from the Immortal Sect personally led thousands of foundation-building monks and thousands of Qi-refining troops to attack with all their might, and the Demon Alliance was in danger.

The senior monks of the Demon Evil Alliance are probably going to fight to the front line and may not even be able to resist. They have no more energy to protect the secret passage.

Su Chen thought about it, this was a great opportunity to sneak into the devil's cave from the secret passage.

"Kill in from behind the secret passage of the Demon Evil Alliance. Their guards are the weakest, but they are the easiest to get military achievements! Brother Su has a good idea!"

Master Lu’s eyes lit up and said in surprise.

"Okay, go to the secret passage to try it! Maybe there will be unexpected gains!"

Ji Yuanzheng nodded.

The monks looked at the fierce battle at the entrance of the Tianfeng Canyon and the demon cave. The tragic level of the front battlefield made people feel numb.

There are some risks when entering through the secret passage, but it may not be higher than the frontal battlefield. Of course, no one opposed Su Chen's idea.

Soon, a group of fifteen monks quietly left the army and quickly sneaked in the dark valley of the Tianfeng Canyon.

Su Chen once carried the demon-warning banner and crossed the entire Tianfeng Canyon for thousands of miles. He had already touched the complex situation at the bottom of the valley.

He naturally knew the approximate location of this secret passage, but he didn't dare to open it in earlier.

Su Chen avoided the nests of monsters along the canyon. About half an hour later, he and everyone came to a cliff and rocky cliff.

This cliff is sparse and there is no strangeness. If you didn't know it in advance, it would be impossible to find a small secret passage here in the Thousand Miles of Tianfeng Canyon.

Su Chen carefully compared the "Tianfeng Gorge Map" in his hand, and the entrance to the secret passage was on this inconspicuous cliff.

The monks searched carefully on the cliff and found a mechanism button disguised as a rock, pushing the rock.

On the cliff, a thick stone door several feet wide and tens of thousands of pounds opened silently.

Everyone couldn't help but be surprised and entered one after another.

There was no one guarding the entrance, and it was obvious that the people from the Demon Evil Alliance felt that it was impossible for anyone to discover this secret passage.

The group of them touched the secret passage that was pitch black and could not see his fingers. After walking for more than ten miles, they finally arrived at the depths of the demon cave.

Compared with the battles and battles between thousands of monks outside the demon cave, the depths of the demon cave seem very quiet, even deadly.

Almost all the personnel of the Demon Evil Alliance were transferred to the front line of defense, but there were no people in the deepest part of the Demon Evil.

Inside the Demon's Cave.

In a dark and dark cave, there were thousands of ragged men and women in mine slaves, each of whom looked numb and haggard, with hands and feet shackles made of iron.

They were all Qi-refining monks captured by dealers from all over the Immortal Cultivation World in China, and sold them to the Demon Evil Alliance as mine slaves. In this dark demon cave, they worked day and night, digging holes and building fortifications.

When the mine slaves get old or die, they will be left behind in the underground fire cave and burned to ashes, as if this person has never been born in the world.

At the door of the huge prison cell, there were only three or four evil cultivators from the Demon Evil Alliance who were guarding this huge divine prison.

These evil cultivators were gathering around a table, drinking a few pots of inferior spiritual wine, playing with a pair of dice bored, betting on who would patrol and watch the night. The loss was extremely annoyed and cursed a few words.

There is actually nothing to guard in this dungeon.

Even though there were mine slaves who had escaped from the mint, no mine slaves could escape from this demon cave alive. They were all dead by accident in a trap or discovered by other evil monks.

Suddenly, a foundation-building monk from the Demon Alliance came to the dirt prison with a deep face.

"Deacon Zhao! Why are you here?"

Those evil cultivators in the dice Qi Refining Stage were drunk and were shocked. They quickly cleaned up and stood up for fear of being scolded.

The evil cultivator of the foundation-building cultivator had no intention of paying attention to them and shouted coldly: "The people of the Immortal Sect are coming in. You guys, immediately drive away all the mine slaves to the blood sacrifice array, and perform the blood sacrifice!"

Those evil cultivators couldn't help but lose their faces with blood.

The Demon Alliance occupies the natural danger of Tianfeng Gorge, and there are also old green-robed monsters and more than ten golden elixir-level evil cultivators, and even support from the Northern Yi barbarian cultivators. How could it be so powerful that it could not hold on so quickly?

This blood sacrifice formation is one of the five most powerful guard formations in the Demon Evil Alliance. The extremely vicious evil formation needs to be poured with a large amount of blood and soul to activate.

The Demon Evil Alliance usually raises these thousands of mine slaves to dig holes. Once the Demon Evil Alliance encounters a crisis, the mine slaves are the best sacrifices to activate the blood sacrifice array.

Since I have built the Blood Sacrifice Formation, I have not activated this formation. This is the first time. When I heard that I was going to activate the Blood Sacrifice Formation, I didn’t expect that the situation was so dangerous.

But the Qi Refining Guards of several of them dared not ask any more questions.

"But there are thousands of mine slaves here. If they sacrifice all of them, they may resist fiercely. We can't suppress them!"

"It's okay, I will personally escort the formation. I will execute it immediately!"

The evil cultivator of foundation-building shouted in a deep voice.

The guards of the Qi-refining evil cultivators in the dirt mint immediately rushed into the dirt mint with fire whips, whipping these mine slaves frantically, and drove thousands of staggering numb mine slaves to the altar of a giant blood sacrifice formation in the demon cave.

The blood sacrifice array is in a blood-colored cave hundreds of feet, and there is a dry pool in the cave. In the center of the pool, a blood-colored crystal stone half a meter tall stands.

This blood-colored crystal stone has a very high grade. It exudes a strong blood-colored evil spirit, which makes people dare not look directly at it.

Around it, there were some green dry tubes, extending in all directions in the demon cave, like the blood of the earth.

"kill!"

The evil cultivator of foundation-building looked at Chi Zi, stood with his hands behind his back, and said coldly.

The four evil cultivators immediately took off their swords and pushed the mine slaves to the edge of the pond and slashed them with one knife. "Puchi", the gurgling blood splattered out and flowed into the dry pond.

Of course, the blood of several mine slaves cannot play any role, and it cannot even moisturize this pond.

But the blood of thousands of mine slaves was enough to fill this pool.

The mine slaves who were originally numb and had no glory were awakened immediately. Finally, they knew that they were all going to be killed here. They screamed in horror and struggled desperately to escape.

However, they were all wearing heavy shackles and digging in the demon cave for many years. Their bodies were already extremely weak, so it was not easy to escape.

The four evil cultivators, great men, were so powerful that Kong Wu, holding a spirit sword, entered the flock of sheep like a tiger, killing them so hard that their hands were tired and numb, but they only killed three or four hundred mine slaves, and finally filled the bottom of the pond with blood and blood.

The evil foundation-building cultivators thought they were too slow to kill, so they used a flying sword and flew through the mine slaves. Suddenly, a large number of heads fell to the ground and blood splattered everywhere.

These bright red blood qi and blood made the shriveled blood on the ground of the pool bulge, as if they began to pound.

The half-meter-high blood crystal seemed to have come alive, and began to strongly absorb blood and burst out dazzling blood. These blood lights shone on the corpses of mine slaves everywhere.

The soul in the mine slave's body seemed to be struggling to come out under the guidance of blood.

"The blood sacrifice formation is about to survive, leave here!"

The evil cultivator of foundation-building could not help but show a look of fear, and quickly turned around and left.

The blood sacrifice formation formed by the lives of thousands of mine slaves is so powerful that it forms a resentment.

Once the blood sacrifice formation is activated, the blood evil spirits and the newly dead mine slave souls will form a powerful group of blood evil spirits, attack and devour all living beings indiscriminately, and will continue to expand with the newly dead evil spirits.

The four evil cultivators in the Qi Refining Stage were even more panicked. They ignored the fact that they went to kill the living mine slaves, followed the evil cultivator and staggered and fled.

The old monster with green robe knew that he couldn't hold on for long, so he had decided to give up this demon cave.
