More than 500 years ago, there was a group of "pioneers" who developed a method of infinitely refreshing the magic cave, or more precisely, excavated the secrets of the magic cave in ancient times, and obtained this method from it.

Each newly descended demon lord has a mark on the demon lord, and this mark is engraved on a special device called the "space key", and then the key is put into the magic energy, and the space supply of the magic energy can be transmitted to the demon lord!

This key device is actually a jade pendant of a special material, which must be engraved with the "Space Array" obtained in the secrets of ancient times, and this space Circle is the spatial channel that opens up the magic energy to connect with the Demon Lord.

After the supply of magic energy is sufficient, the demon lord will revive and finally realize the resetting of the demon cave!

The three major families relied on the reset of the demon cave to make money.

But there are three unsolved mysteries, or hidden dangers.

One is that after the demon lord was killed for the first time, the secret treasure on his body was taken away, why did the resurrected demon lord reappear on the original treasure that was not brought by the body. The only reliable guess that no one knows, including the author of "The Origin of the Demon Cave", is that the Demon Cave still has some kind of connection to its original world, and this connection cannot be seen or found by anyone in the world.

The other is that the energy storage pool relies on an "energy conversion array" to convert the unknown energy in the leylines into magical energy, where does the energy in the leylines come from? Whether it will destroy the leylines and cause greater disasters is unknown.

Another is that the space circle is an existence that transcends all the laws of this world, and no one knows its principle.

Their country, the Qinghe Alliance, once explicitly forbade the unauthorized reset of the demon cave, and demanded that the demon cave must be cleared to eliminate future troubles.

However, driven by profit and long-term stability, the country has let its guard down.

On a more important level, the reset of the Demon Cave can allow cultivators to have a stable cultivation path, and promote the overall strength of the country to be greatly enhanced in a few hundred years.

As a small border country in the eastern part of the Dragonspine Continent, the Qinghe Alliance has a strong sense of crisis, and in this continent, the collapse of the country is like five dynasties and ten kingdoms.

Privately controlling the Demon Cave has become the country's most open secret.

Even if there is an occasional uncontrolled Golden Demon Cave, causing turmoil on one side, it will eventually be ruthlessly crushed by the state apparatus.

Until the last few coalition regimes, they were bent on opening up territory, seizing more demon cave resources, and improving the overall national strength.

The Demon Cave has become the world's greatest focus of interests.

Lin Yuqing took advantage of the faint light and walked down the stairs.

But after only two steps, she suddenly stopped.

Because, in the midst of her footsteps, she heard another voice, a sound that coincided exactly with her footsteps!

Source, in the corridor she had just walked through.

Lin Yuqing held her breath, the monsters in captivity here are not trivial, there is no shortage of demon lords in the purple demon cave, she is a 7-rank martial artist, she may not even have a chance to escape.

It was only quiet for a while, and the voice seemed to be uncontrollable, and the sudden and rapid footsteps of "kick-kick-kick" echoed repeatedly in her ears!

Lin Yuqing's heart had already risen to her throat at this time, the fear brought by the unknown power in the darkness was huge, how could a 17-year-old girl bear it.

She held on to her body and didn't go limp.

Every time that voice sounded, it was a great torment for her.

It's close!

It's getting closer!

Lin Yuqing clenched her fists, she had no way to retreat, she could only desperately punch towards the corner of the stairs!

"Smack-"

A crisp sound reached her ears.

That hand, with warmth, is extremely powerful.

She looked up tremblingly and saw a young, handsome, resolute face, just yesterday, that face, in the moonlight of the streamer, made her heart lose its guard.

Lin Yuqing's heart swelled with infinite surprise, and she desperately threw herself into Ishikawa's arms.

This man's chest, which is two years younger than her, makes her feel safer than the whole world.

Ishikawa was also slightly surprised, but fortunately, he judged that he was a human just now based on the other party's breath, and he didn't make a heavy hand.

He patted Lin Yuqing's shoulder, looked at her tear-stained face, and thought that she had endured too much in just one day.

"Ahh

He pushed Lin Yuqing away and shouted, "Why are you biting me!"

Who knew that Lin Yuqing had tears on her face, but she squeezed out an ugly smile, and greeted it again, hugging Ishikawa's arm tightly, and she didn't know how to avoid suspicion.

The body that is already ripe is not rubbed against Ishikawa in depth.

Ishikawa had a black line on his head, and thought to himself, if this woman is shameless, it will be really terrible.

"You are not allowed to leave me. Lin Yuqing said suddenly.

Ishikawa: "I'm not your servant, why?"

Lin Yuqing choked his mouth: "Who made you ignorant, and you still showed me a face in Shuangshui Town." ”

Damn, Ishikawa scolded in his heart, this woman really holds a grudge.

Ishikawa pulled Lin Yuqing off his arm vigorously, and his tone softened a little: "Okay, I'm not right." You helped me, and I'm not going to leave you alone now, okay. ”

Lin Yuqing's ugly face just now has eased a lot, and her head is like a chicken pecking rice.

"Why are you here. Ishikawa asked.

"The cultivators of the family are all dead, my grandfather and uncle are dead. The rest of the family decided to evacuate to Longwu City, but, according to the Lin family's emergency plan, the energy storage tank must be destroyed. Lin Yuqing said as tears fell again.

Ishikawa also sighed: "Don't be too sad, there are eggs under the nest." We should now pick ourselves up and do what we have to do. ”

"Hmm!" Lin Yuqing nodded, suddenly had a backbone, and continued, "I found that the rooms where the monsters are kept in captivity on this floor are all open, but there are no traces of monster activity upstairs, I don't know where the monsters have gone, so be more careful." ”

Ishikawa frowned: "It's very likely to be downstairs! You must be careful, the situation is not right, run immediately!"

"Hmm. ”

"If I'm not mistaken, these monsters are bathing in the energy tank!"

"What!" Lin Yuqing said, "They will become stronger when they absorb the magic energy!There are still a few purple demon lords in it, what should we do." ”

Lin Yuqing cast a plea look at Ishikawa for help.

"The soldiers will block, and the water will cover the earth. However, this is not what worries me the most, what I am worried about is who will release them!"

Lin Yuqing shook her head blankly: "Maybe it was a mistake when the staff evacuated." ”

Ishikawa sneered: "They all want to leave more time to escape, who will release the monster to cause trouble for themselves." ”

"What do you mean?"

Ishikawa: "Your family has an inner ghost!"

Lin Yuqing exclaimed: "Impossible, there are only women and children left in our family, and it is impossible for us to have the ability to do such a thing." ”

"Don't you think it's a bit strange that your grandfather died as a powerhouse of the Martial Sect realm?"

Lin Yuqing: "What the hell do you mean!"

"I'm not sure yet, but the truth is down there!"

Ishikawa didn't explain much, and took the lead in going down.

This staircase is extremely deep.

When you go down, there is a huge cylindrical space, and through the flickering light, you can see a huge transparent container standing in the center, which is the energy storage tank.

Elsewhere there are a number of small chambers that are connected to the storage tank with tubes.

This moment gave Ishikawa the illusion of stepping into a science fiction film.

There was no sound here except the crackling sound caused by poor electrical contact.

This is not what Ishikawa expected, but the quieter it is, the more terrifying it is.

He was not careless, and carefully checked the cultivation cabins one by one, but they were all empty.

Just when Ishikawa was wondering, Lin Yuqing screamed "ah-", which frightened Ishikawa.

He looked back sharply and found Lin Yuqing sitting on the ground, pointing to the energy storage pool with his finger, his face full of horror.

Ishikawa followed his fingertips.

An extremely rotten face, unable to distinguish between man and beast, was sticking to the transparent glass, staring at them with two black holes!

That rotten face disappeared in an instant with the flow of the magic energy solution inside!
