It may be that it is difficult to accept the situation in front of them for a while, or it may be that they subconsciously know that their escape is useless, and everyone just takes a few steps back mechanically, and then stands in place as if they have been robbed of their souls.

And in the next moment, the giant tentacle had already retracted into the water with a "bang", causing a splash. Except for the fluctuations on the surface of the water, the fish-man patriarch acted as if he had never existed, and the fish-people next to him had already scattered and ran in the direction of the cave.

When the fish-man patriarch was swept away, he was only seven or eight meters away from a few people, and the shock could no longer be expressed in words. Vane felt like his body had lost his strength and his legs were unsteady. Could this be the demon in the diary? His whole body was as cold as falling into the abyss, and he didn't know what secrets were hidden underneath the earth.

"What the hell was that?" asked Simpson, a man who never seemed to know what fear was.

"That's probably not something we know...... We first need to get out of this place and, of course, take that scepter with us. Vane said, pointing forward, the silver scepter lying on the gravel ground near the water's edge.

By voting, Felder successfully "received" the task. He'd even given Wayne an account to return his twenty gold coins back to his father in Gustown. Eventually, Felder sweated profusely and brought back the scepter.

The scepter was heavy in his hand, and the body of the scepter was silvery-white, seemingly made of Mithril, with exquisite patterns engraved on the surface, and the emerald inlaid at the top was faintly shiny.

"This is supposed to be the Prophet's Scepter, and I can feel the natural magic on it. But...... It's so slimy, it's disgusting. Ace pouted and returned the scepter to Felder again.

"Let's get out of here first. Vane said. At this time, most of the people recovered from the panic, turned around and walked to the rear. What the hell was that tentacle? Vane's doubts outweighed his fears, he had never heard of or seen anything like it in books. The cave passage, which is not very long, seems to have no end in sight, and the only sound is the heavy breathing of a few people.

"Human, we meet again. The dark green fish-man sacrifice appeared in front of the cave exit with a group of fish-men, and everyone immediately became vigilant.

"Don't be nervous, I don't mean it badly. I already know the death of the patriarch, and I can only blame him for his own greed. The fish-man priest staggered forward two steps and said. "You can call me Green, but why I speak your language is another story. First of all, I have to explain the current situation, and let's talk about it as I go. ”

The members of the Black Ghost and a group of fishmen walked forward in the black cavern passages.

"Our tribe has lived in the darkness of this underground for a long time, and there is plenty of water here, so we don't have to worry about food. But you should have seen that horror as well, the intricacies of the underground waters, and the fact that they are everywhere in the water, where people die every day in search of food. After saying that, the fish-man priest named Grimm seemed to sigh softly.

After hearing this, everyone was silent, and the atmosphere became a little gloomy.

"I'll take you somewhere, maybe you'll be interested. Fishman Sacrifice Green said suddenly.

The group followed the fish-man in the darkness, and although it was still dark, Vane felt that his eyes could better adapt to the darkness, and the details of the walls on both sides were already faintly visible. Along the way, you will encounter a number of ancient elf-style architectural ruins, most of which have been dilapidated beyond recognition, and the wonders of nature have combined them with the caves and rocks.

The journey was not long, and after ten minutes, everyone came to an ancient ruin. This temple-like building is in the same style as the other ruins you've seen, with intricately carved stone pillars and walls made of large pieces of machined rock. Strangely enough, it did not collapse into the ground or be buried in rock and earth like other buildings, but rather appeared to have no signs of age, or even intact.

Grimm took a few steps forward and stopped, pointed to the wall in front of him, and said, "It seems like a door here, but no matter how much we try, we can't open it." Some of you are magicians, and I think there might be a way. ”

As Fishman Green said, there is a "door" in the middle of the tightly knit wall at a height of one meter, and in the eyes of the fish-man, the door is actually just a raised disc. There was a small keyhole in the middle of the disc, and based on previous experience, the entire wall was probably the real door.

The stone disc is made of a single piece of rock, with a smooth and flat surface, and the fingers do not feel anything, and it does not seem to touch the stone disc or feel any temperature. Could this be...... Vane thought of a word he had heard in the Academy of Magic—magic array. Vane looked at the wall next to him, and sure enough, it was just as smooth, and his fingers seemed to be separated by a layer of invisible things. The entire building must have been protected by a magic circle.

Strictly speaking, a magic circle is a technology stack, consisting of a series of magic-related theories and techniques, such as magic state preservation, magic delay, magic buff, etc. Magic circles can be completed by one or more magicians, as they require a large amount of magical energy, and are usually supplemented by a large number of magic stones.

The arranged magic array can be enhanced several times or even dozens of times in terms of effect, duration, and range, and the state of the magic can be saved. If the target enters the range of the magic array, the fireball will recover from the saved state and attack the target, and the power of the fireball will also be greatly enhanced due to the buff of the magic array, and the effect can even exceed the high-level group magic of the light system - fire meteor.

And the magic array in front of him has exceeded Vane's cognition, such a huge building is shrouded in the magic circle of the magic barrier, and it still exists after thousands of years, which is almost impossible, but there seems to be no other better explanation for the scene in front of him.

"It's ...... Magic Circle?" whispered as Ace rubbed her hand lightly against the wall.

"There seems to be no better explanation other than the magic array constructed by the magic barrier, but if this relic is left by the ancient elves, this magic array has existed for at least a thousand years, and it is almost impossible according to theory. Vane said slowly, but his heart was up and down. Magic, is it really what the teachers in the magic academy say?

"Since this magic circle is so powerful, can't this door be opened?" Felder stepped forward and kicked hard with his foot, apparently the wall didn't react except that he felt like he was kicking on the iron plate.

"Generally speaking, that's true, but we seemed to be extra lucky today. Vane said as he pulled something out of his bag.
