The master and apprentice of the Demon Hunter quickly moved from the east to the west, climbed two slopes along several dry vines, and exploded several nests of miasma in the middle.

Smoothly enter a spacious room with neat marble floors.

Unlike the rough-shaped and ruined caves, this room is decorated more exquisitely and gorgeously.

The two stopped on the steps behind the door and stared at a stone tablet with ancient words.

Dark Gold's pupils slowly rotated, and Roy easily recognized the semantics with the inheritance of a quarter of the elves.

"If you stare into the abyss, do you have to lift it?"

The low voice fell, and in response, a cold breath seemed to whistle in the empty hall.

Roy raised his eyebrows.

The bald man fell into silence.

"What does this sentence mean?"

The feeling this ancient saying gave him-

It is like a person who is in despair, struggling wildly before his death, but going astray; moving forward with difficulty, and finally achieving some kind of success?

"Fever, extreme...extreme means danger, not a good thing." The bald man looked not far away, in the middle of the room, the Oaks brothers, and Thirrit was standing on the edge of a circle of columns.

"Let's go, don't waste time, let's go first."

...

"Three, have you found the key? Don't tell me, you've been staring at this thing."

When the two of them approached, they found that the central pillar was terrifyingly high, at least ten meters, connected from the ground to the ceiling, and the hard surface was embroidered with circles of rice-like patterns.

It's like a giant cage.

It's just that the gap between the cage railings is too large.

Free entry and exit.

Between every two pillars, a simple and dignified human-shaped stone sculpture stands.

They are like giants standing in the shadows silently, pale, cold stone eyes staring at the unknown one.

"We killed the demon spirit... and then found a record..." Oaks showed the two of them a page of kraft paper that had been on the past, which seemed to be a page of research notes-

"We conducted a series of studies on the genes of water ghosts as ordered by our teacher Irenius Wasteingard.

After feeding trogatotoxin, all the subjects fell into a coma. After twenty-four hours, all of them lost their signs of life and the experiment could not continue.

Signature: Matiou Sikura”

...

"This is the right one!" Roy took out the previous receipt and said excitedly, "This teacher and the golem buyer are the same person. Renius Wasteingard, the owner of this secret laboratory!"

"The key to opening that door must be on him!"

"Calm down, boy..." Seret immediately poured a bucket of cold water, "We searched all this place, except for this research note and a demon spirit who died. Even a mouse cannot be seen, let alone the key!"

"Maybe that mage had abandoned the entire laboratory and hid in somewhere."

"In the end, I have to get some explosives to explode the laboratory!"

"No! Since you have encountered the demon spirit... it means there should be the remains of a dead man nearby..." Resou said with a determined look on his face.

"Sorry, there are no remains..." Maojiu suddenly walked to a statue and looked closely. There was a small movable lever on the pillar. "But I discovered some mechanism."

Maojiu gently pulled the pull rod down.

"Hydon-Hydon-Hydon-Hydon-Hydon-Hydon-Hydon-Hydon-Hydon-Hydon-Hydon-Hydon-Hydon-Hydon-Hydon-Hydon-Hydon-Hydon-Hydon-Hydon-Hydon-Hydon-Hydon-Hydon-Hydon-H

The ground was shaken and dust was overflowing.

The tall stone sculpture, originally facing everyone, immediately responded and rotated ninety degrees in a clockwise direction.

"Adjust their orientation, you should get the answer...skeletons and keys!"

"The sneaky warlock likes to do these nerve-wracking things. What are you waiting for?" The Hood Hunter walked straight to the westernmost pull rod, "Let Mr. Oaks solve this puzzle!"

"Idiot! Mathematics idiot!" Seret smiled disdainfully, "Do you know how many possible combinations are there? Even if you transfer to three days and three nights, you can't finish it!"

Roy was blinded by the sight of the words and saw seven statues surrounding them, each with four orientations.

"This means the possibility is, to the seventh power of four..."

Roy's heart skipped a beat, "More than 16,000 possibilities!"

Everyone's faces changed drastically.

"So what? After the trial of grass, what we don't need is time!" Ox rubbed his nose, quickly restored his fighting spirit, randomly selected a statue, and began to pull the mechanism, "Even if you use the stupidest method and spend more time trying one by one, it is better than standing still, just complaining!"

"Wait for fools! Don't you make any marks? I can guarantee that you will be messed up in less than a hundred times, and start over!" Seret began to cooperate tacitly with his brothers, and Flius walked over to help.

A fire burned in my chest,

He had to untie the mechanism, open the lab, and meet the cat-spike demon hunter in Roy's premonition.

...

Roy stood there, his eyes turned and he fell into thought.

He only remembered that there was a laboratory under the Temple Island, but the solution of the mechanism had long been blurred.

"Little devil, come and help!"

"This research note... Reso, I remember that the water ghost is obviously immune to toxicity," the young witch hunter asked a strange question. He did not intend to turn the mechanism rigidly. There must be some trick, "Why do you fall into a coma and die after injecting tuterophorus toxin?"

"I am not a warlock and have never done such detailed experiments, but as far as I know, the poison in the body of pufferfish is different from other poisons. It is considered a neurotoxin. Its toxicity is the highest in nature and its mechanism of action is completely different from other toxins."

"Twobufish toxin will not directly corrode or damage the flesh and blood. After being absorbed, it acts on the biological nervous system, paralyzes the nerves, causing them to lose all their ability to move, and thus dies..."

"Even if it is a water ghost, there are nerves in the body."

"I see."

The bald man patiently spread the subject and cooperated with his three companions to pull the pull rod.

Roy repeatedly searched the receipt and the research notes, and searched the entire room twice.

Nothing was found.

"Roy, as a junior, he actually sat down to see his senior take the coolie. If you continue to be lazy," Ox threatened, "If you crack the mechanism and find something valuable, it is owned by your own. Don't think about using it to confiscate it again!"

Roy shook his head and smiled, treating this joke as a breeze in his ears, muttering to himself, "With such a complex mechanism, can the researchers just remember the answers based on their brains?"

"There should be some kind of hint?"

But I have read both documents.

I searched all over the place.

"Did I overlook something?"

What is not used?

He closed his eyes and filtered all the experiences after entering the cave again.

Two minutes later, he suddenly opened his eyes, and his dark gold's pupils flashed with a strange look.

"Is that the sentence-"

A strange ancient saying above the stone tablet!

"Gathering into the abyss, you have to lift it up."

Staring - These seven stone sculptures, with expressionless faces, don't they look like they are staring at something?

Then I should turn the statues so that they face the so-called abyss and untie the mechanism.

But where does the abyss mean?

Roy looked around and saw that outside the statue, there was no distinctive feature on the four walls of the entire room, which was in line with the meaning of the abyss.

So--

He crossed the busy four witch hunters.

Enter the statue and surround the center, a circular clearing.

Squat down and tap the marble floor with your fingers.

"Bang, bang..."

The following is empty.

"Guys, stop!" Roy suddenly stood up, "I think, I know the answer to the agency!"

...

Two minutes later.

With the cooperation of the five witch hunters, all the statues were adjusted to face the central area.

"Click--"
