Just as Su Chen, Anu and others were opening many treasure chests in the treasure house of the Demon Cave to collect and scrape the goods, they met Wu Min'er appearing.

Inside the Demon Cave, the strong defensive array that the Demon Demon Alliance had spent hundreds of years building was broken by dozens of Jindan monks, thousands of foundation building monks, and tens of thousands of Qi refining period monks from Penglai, Ten Thousand Beasts and other immortal sects.

Under the siege of several Jindan monks, the green-robed old monster was seriously injured, and a bloody hole was punched in his chest. Seeing that the situation was not good, he immediately abandoned his battle and fled, and fled into the depths of the demon cave with a group of dozens of cronies.

The Demon Demon Alliance couldn't help but be defeated, four or five Jindan evil cultivators were killed on the spot, and the thousands of demon monks at the bottom were even more killed and injured, and the rest of the demon monks could only flee in panic and were chased and killed by the immortal sect monks.

The green-robed old monster was fleeing in the cave, and when he saw an arm-thick bloodline on the cave wall, withering again, he couldn't help but look embarrassed, "Damn, why did the blood sacrifice array stop?"

Before him, he ordered a cronie to kill thousands of mine slaves and activate the blood sacrifice array.

Even if the battle is defeated, those fallen monks will be born into resentful spirits, causing great trouble to the various Immortal Sect monks, giving the remaining Demon Demon Alliance disciples enough time to escape.

However, the Blood Sacrifice Array, which had already been activated, had just had a little effect, but it had fallen back again.

After a while, the green-robed old monster led his cronies to the blood pool, and saw that the half-zhang high blood crystal in the blood pool had disappeared.

"The blood crystal was actually poached by someone, no wonder the Blood Sacrifice Great Array gave up halfway!

The green-robed old monster couldn't help but be annoyed, and spit out a mouthful of blood angrily.

This blood crystal stone is the blood marrow ancient stone dug up in a dangerous ancient land in the cold and barbaric land of Beiyi in his early years, and it is likely to be the product of a bone marrow petrification of ancient demon beasts.

Such a large block of blood crystal is very rare, and he used it to set up a huge demon blood sacrifice array in the demon cave, bringing chaos to the enemy at the most critical time.

But this blood crystal was dug up, and his hard work was in vain.

"Alliance leader, hurry up! The Immortal Sect monks will soon catch up, and they will catch up, but they won't be able to escape!"

The green-robed old monster's face was pale, and his qi and blood were seriously lost. Surrounded by a group of loyal demon monks who have served for more than decades, they are anxiously persuading.

The green-robed old monster knew that the general trend was gone, sighed, and took this small group of cronies and monks to escape from a secret passage to the back mountain of the Demon Cave, either to escape to the bitter cold land of Beiyi, or to make a detour to the land of Shenzhou.

There are three secret passages in the Demon Cave, and this is the safest of them.

"Hateful, Penglai Immortal Sect destroyed my Demon Demon Alliance! This revenge, sooner or later I will have to come back with a thousandfold revenge! Activate the 'Earth-Shaking Array' and destroy the Demon Cave. ”

The green-robed old monster fled to the exit, looked back at the hateful gaze, and glanced at the deep demon cave passage. He ordered his cronies to open an extremely hidden formation mechanism placed in this passage.

This is the last big array he arranged, the "Earth-shaking Great Array".

Destroy the entire Demon Cave, and the jade will be burned, bringing a devastating blow to the various Immortal Sect monks who have attacked the Demon Cave.

...

"Boom~~!"

In the depths of the Demon Cave, one violent explosion after another occurred.

The flints and oil drums that had been buried a long time ago were continuously detonated by the earth-shaking array, and they trampled on the key rock wall support in the demon cave. This was followed by a wider collapse.

The demon cave shook violently, the ground shook, and the rock cave collapsed in large areas.

The monks of the Demon Demon Alliance, who were fleeing for their lives in the demon cave, as well as the monks of the Immortal Sect who were chasing them, did not expect such a drastic change, and their faces were shocked.

Su Chen walked in the front, taking Anu, Wu Qiao, Old Master Lu, Zhang Xiaodi and others, and was walking along a secret passage in the direction of Tianfeng Canyon, preparing to evacuate the Demon Cave.

They took several chests from the Cave Vault, each with one or two, and the harvest was abundant. Worried that if they encountered that Jindan resentful spirit and Demon Demon Alliance cultivator again, they would naturally flee as the best policy.

Suddenly, Su Chen felt that the earth was shaking violently, and the cave in front of him shook violently, not understanding what was happening.

"Click~!"

A boulder of nearly 100,000 catties was shaken, fell from the cave wall, and smashed down on Wu Qiao, Old Master Lu, and Zhang Xiaodi behind the team.

This boulder fell down, and the Qi Refining Stage Monk would also be smashed into meat cakes.

Wu Qiao raised his head suddenly, burst into a shout, his arms and muscles burst out, and he burst out with amazing divine power, withstanding a 100,000-jin boulder that collapsed above.

The huge impact shook him and spurted out a large mouthful of blood.

"Quick, rush over!"

Old Master Lu and Little Brother Zhang were shocked and hurriedly rushed through this cave where boulders kept falling.

A section of the cave in the distance in front of him has also collapsed, and it is impossible to pass.

Wu Qiao abandoned the 100,000-jin boulder and fled to the front. With trembling hands and feet, he sat down on the ground.

The impact of the boulder shook him out of his internal injuries.

"Brother Wu is injured, hurry, is there a good hemostatic pill?!"

Old Master Lu looked anxious.

When everyone saw that Wu Qiao was injured, they couldn't help but panic.

"I have a few second-order high-grade hemostatic pills here, give them to him first. ”

Su Chen took out two second-order top-grade healing and hemostatic pills from the pill bottle and gave them to Wu Qiao.

He helped Wu Qiao to control the blood breath and was a little relieved, "Brother Wu was injured by the boulder, and he can recover after taking the hemostatic pill and cultivating for a few months." ”

"It's not a big deal, I have a lot of strength, I can bear it!"

Wu Qiao grinned, indicating that there was nothing in the way.

The group of five fell silent.

They were trapped in this dark cavern, unable to get out.

The violent shock in the demon cave lasted for half an hour before it gradually subsided. Occasionally, there will be a slight small collapse, causing a sustained tremor.

The entire cave fell silent.

The sounds of running for their lives and chasing and killing are gone.

Su Chen stared blankly at the entrance of the cave that was blocked by the falling stone.

The devil knows what happened suddenly, and the entire demon cave actually caused such a violent collapse.

Come to think of it, it is probably because the Demon Slayer Alliance has moved its hands and feet and arranged the formation to destroy the Demon Cave in advance, so there is such a huge movement.

In the middle of the sound, Su Chen smiled bitterly, and said with a helpless look: "Dig it! Dig a way out." Brother Wu, you are injured, rest first, let's dig a few of us. ”

The huge rock that collapsed in the demon cave weighed more than 10,000 catties. If a mortal can't move it at all, it's a dead end, and there is no hope of escaping.

They have three foundation building monks, and they have great strength to move the tens of thousands of catties of huge stones, and there is hope to dig them out. Old Master Lu and Little Brother Zhang carried those thousands of catties of small stones.

They are in the depths of the demon cave, and it will undoubtedly take a long time to dig out. It took more than half an hour to move away the boulders in front of me, which were often tens of thousands or 100,000 catties, and only to dig dozens of zhang away.

Immortal cultivators usually use mana and divine thoughts, and have very little physical strength.

The monks were tired from their work, hungry and hungry. This kind of gravity work is the most exhausting of the monk's physical strength, and it needs a lot of food to replenish it, otherwise it will not be able to bear it.

Su Chen thought of something, took a few demon snake eggs from the Sumeru ring, and gave everyone a cushion.

The demon snake egg can not only replenish physical strength, but also has a small amount of vitality in it, which is a great supplement for cultivating the original spirit.

Fortunately, he has enough food, there are as many as five hundred demon snake eggs alone, as long as there are spirit stones in the spirit mountain, the food is even more useless, otherwise he can starve to death in this cave.
