"A person who finds here in advance may find something. If he can tell us something, we don't need to start looking for clues from the beginning."

Zelin always believes that before doing anything, it is best to collect as much useful information as possible and find helpers, just like before hunting monsters, you have to talk with witnesses and check the attack scene to judge the enemy's strength and level.

"I don't have the ability to perceive like a demon hunter, so go and look for it. Albert and I stay here to see if there are any mechanisms or illusions." Cynthia shrugged, not interested in it. "When we find something, you'd better come back as soon as possible, otherwise we won't wait for someone."

"No problem."

There were drag marks on the ground, indicating that the person fighting the monster was injured. In this case, he could not go far. Zelin estimated that it would not take long to find the other party-or the corpse.

Following the trail of drag, Zelin walked into another circular hall. The hall is very dark, and a step divides the hall into two parts. The Griffin badge did not move, Zelin followed the traces step by step up the stairs. The traces finally disappeared behind a slate wall.

"Slate wall." Zelin stepped up, reaching out and touching the wall. "It's physical. It is impossible for an ordinary human to pass through the wall..."

Soon, the demon hunter set his eyes on the rusty torch stand beside the wall.

The torch holder is upside down. Even a lizardman, it is impossible to fix the torch head down on the wall.

"So..."

He grabbed the torch holder and turned it vigorously. The torch holder turned abruptly for a half turn, then bounced back and returned to its original shape. Zelin stepped back and stared at the wall in front of him.

Accompanied by the rubbing of stone bricks, a slab of stone retracted behind the wall, exposing the dark hole behind it.

"Interesting."

There was no trace of light inside, and even the eyes of the demon hunter couldn't catch any light. Zelin fumbled in his pocket and found that he seemed to have forgotten to bring something for lighting when he came out this time.

But this is not difficult for him.

Zelin drew out the silver sword behind him, and the magic infusion rune on the sword emitted a bright orange light. With this ray of light, he saw clearly the situation in the secret room.

This is a small rectangular secret room. The wall on one side of the secret room collapsed, and the fallen stones were piled on one side, blocking the exit at the other end. At the side door of the secret room, there is a handle similar to the base of the torch holder outside. It may be the mechanism that controls the door inside. At least the outer mechanism was made by later explorers to place the torch. Under the pile of rocks, lying a sturdy bald man, his eyes closed, motionless, his chest and abdomen were bloody, and the solid breastplate could not stop the spikes that the scavengers sprayed when they exploded at close range. Zelin knelt down, put his fingers under his nose, tried his heartbeat again, and shook his head.

"Seriously injured, she hid in a safe place and waited for rescue, but died due to excessive blood loss."

On the corpse, Zelin found the badge of the Kariyas brothers.

It's a pity that he can't ask any answers here.

The demon hunter carefully searched the corpse again, and finally, he found a tattered piece of paper under the breastplate. It seemed to be a letter in an envelope, but it was soaked in blood that it stuck together. Zelin carefully separated the letter paper and took out the part still carrying the handwriting.

[...The old stupid donkey has been defaulting on the payment that should have been given to us, and we can't continue to drag on here. Let other people take orders and make more money before the fall. I stayed with another brother. As long as he doesn’t hand over the money, we will make him uneasy forever...]

Zelin tried hard to see the rest, but the coagulated blood had already covered up the writing. But even so, this letter has left some clues.

Someone owes the Carrias brothers a sum of money, and hired them before, but has not paid the remaining money. It seems that most of the people in this mercenary group have already left, and they have been commissioned to make money elsewhere, just like this soldier. They only left a few people in the city, asking for compensation from their previous employers. Then, Zelin only needs to determine which noble camp has debt-collection mercenaries in and out, and then he can judge who hired the Kariyas brothers.

Putting the letter in his pocket, Zelin left the hall and returned to where Cynthia was before.

"Have you found someone?" Two professors and two warlocks were standing in front of a stone wall. Hearing footsteps, Cynthia turned her head and asked Zelin. "Any clue?"

"No." Zelin shook his head. "The mercenary is dead."

"I said, searching for the wounded in such a dangerous place is just a waste of time." She waved her hand. "But we found a clue. There is an illusion here and something is hidden in it. Step back, Demon Hunter, the anti-magical metal on your armor affects my spells."

The first thousand eight hundred and eighty-third chapter Dihenner's puzzle

Cynthia drew a pentagram magic circle on the ground.

Along with her spells and gestures, one layer of walls gradually faded, revealing the stone gate carved with vines.

The hall lights up.

An eye was opened above Shimen, and the light from the eye instantly illuminated the entire hall. The magic eye scanned the five people present. The hall rumbled, and the heavy roar echoed in every corner of the hall.

"Visitor, five people." A black spot in his eyes moved back and forth, and the demon hunter suddenly thought of the evil eye of Sauron on the evil black tower. "Answer the puzzle and enter."

"This must be Di Henner's laboratory! Di Henner's laboratory! Treasure! The treasure is real!" The two professors clenched their fists in excitement. If it wasn't for the dangerous magic light, Zelin believed that they would come forward and touch the door, and then knock something down with a tool. "Look, the standard Dihenna treasure! Magic, anthropomorphic golems, puzzles! This genius mage has in-depth research on golems. It is rumored that his golems have language ability. Although they can't appreciate poetry, they can behave like humans. Talk to outsiders."

"What good things can the savages leave? The time for admiration is over." Albert snorted disdainfully. "Hurry up and find a way to open this door. Only after the contents enter the Imperial Academy of Sciences, can it display its true value."

"By the way, there are puzzles, let's talk about the puzzles, guardian, tell us what the puzzle is?"

The professor looked at the magic eye.

"When I'm caught, you can hold my feet." The two beams of light in the statue's eyes scanned back and forth, sweeping across everyone. "Although I don't have a needle, I can penetrate it. What am I?"

"Typical Dihenner style." Another professor said. "He lived for hundreds of years, but he still liked pranks, just like a small child. But no one can deny how great his research results are."

"Think about it, what is the riddle, Demon Hunter?" Cynthia looked at Zelin. "What do you think it is?"

"Are you kidding?" Zelin raised his eyebrows, spread his hands, and looked at the others. "Look at the people present. Two high-achieving students from the Imperial Academy of Magic and two professors at the most famous Osenfurt Academy in the North. None of them are honorary titles. They are all genuine. Then you must have one who has never attended a university. Demon hunters to solve the problem? Please, you are the explorers. I am responsible for dealing with the water ghosts, scavengers, and Angleworms that may be encountered on the road, or the out-of-control golems in the laboratory."

"Don't worry, this riddle is a piece of cake."

Professor Gaspar cleared his throat and stepped forward. Opened his mouth, his voice was loud and loud.

"The answer is-pain."

The Griffon badge buzzed and vibrated.

Zelin raised his hand and Alderfayin hit Gaspar, who flew out and knocked his head against the stone wall. The next moment, a hotter light burst from his eyes, bombarding the place where Gaspar was just standing. The light was so strong that other people around had to raise their arms to resist the heat waves coming.

"What is this...?!"

"Stop it!"

The light began to shoot in other directions along with the rotation of the eyeballs, and anything touched would wither under the high temperature and melt in the light. Albert waved his staff, chanted a spell, and a light white shield appeared in front of him. The light bombarded the shield, and Zelin could clearly hear the creak of the shield when it cracked.

"Get out of the way!"

Albert and Cynthia fell to the sides before the shield shattered, and Zelin threw a bomb backhand. The anti-magic metal bomb exploded in the magic eye, and the burst of emerald green dust instantly enveloped the magic eye, and the light emitted from the eyeball dimmed a bit.

Zelin threw two more bombs at the same time.

The fire flashed, and the shadows covered the hall again.

In the darkness, there was only a heavy gasp.

"What happened?" Harry was in shock. "What is that?"

"Devil's gold temporarily hinders the flow of chaotic magic." Zelin covered the tip of his nose, and the devil's gold floating in front of the door made him feel uncomfortable. "Fortunately, our ancient genius has not studied the topic of anti-magical metal. It seems that if someone answers wrong and doesn't kill one, the magic eye will not stop."

"Can Anti-Magic Metal solve it? Very good, then take out all your bombs and get rid of this door." Albert said.

Zelin didn't look at him, but turned to Cynthia.

"You have to pay me an extra payment then."
