Everyone leaned down to look at the narrow arc on the ground, which was as monotonous and abstract as the lines on the jagged walls, and it was difficult to grasp the intention of the maker, and the pattern ahead was hidden by the darkness, perhaps with more hints.

Tarrant stared hesitantly at the ground, to see the whole pattern, he had to open his vision, someone had to go over, and the right people were limited, it was when chivalry came into play, he just wanted to get the safety of his teammates again, "Rex, are you sure this wall won't close?"

"I just think of the wall and the rest of the aisle as a whole," Rex maintains the most conservative point of view, i.e., disagrees and disagrees.

"Well, maybe we should give it a try," Tarrant said, standing against the right wall, "and watch the line go, the clue must be in it." ”

"Wait", Kitty walked up to him, "what if the walls could coalesce?"

"......" Tarrant innocently swept his teammates over embarrassing questions that were difficult to answer, "Ma'am, it's uneasy for me to come up with such an idea before I go. ”

Kitty put away her smile and continued: "It is more appropriate for me to go, if something happens, the bear's strength can last a little longer, and the chances of survival are higher." ”

"The bears are too big, and going in just adds unnecessary risk," Tarrant politely rebuffed the druid's kindness, "It's just right for me to go, you can pick me up here." ”

The teammates no longer raised objections, and Tarrant straightened his spirits, "Guys, pay attention to the clues, don't let me go in vain", he took the first step against the right wall, the horizontal lines on the wall continued to extend towards the front jagged, Tarrant noticed that the reverse did not set those horizontal lines, proving that these lines were indeed clues to enter the passage.

Tarrant waved his torch down, allowing his teammates to see the ground pattern, or an arc, this time the elves seemed to apply their visual art to the simplest lines, allowing the cracker to find clues from the abstract patterns, hoping that Katrina would be inspired by it, he looked back, the mage was sitting against the wall, staring seriously into the aisle, she had never sat in such a dirty place before.

Tarrant kept his breath steady, keeping his nerves at the most sensitive level of reflexes, so he almost pulled out his katana when a dangling brazier suddenly appeared on his right hand.

The brazier appeared at the right time, Tarrant was worried about how to light up the whole aisle, this was the best way, he pulled down the brazier, the fuel in it had dried up, and new materials needed to be added, he took out the pine oil bottle and poured a few drops, the torch was lit, and the faint flame slowly rose, illuminating the things in the right side of the passage, he turned around and asked, "Is there any clue?"

Rex shook his head, "The lines are descending and incoherent, and the patterns on the ground are abstract. ”

"Okay," Tarrant sighed, "let's look forward to what's ahead." ”

The torch gradually moved forward, and new lines appeared next to the arc on the ground, intertwining with each other, spiraling in all directions, "Look at this", Tarrant excitedly reminded, "It must be a clue", he waved the torch vigorously and tried his best to present the whole picture, "It seems to be...... Some kind of mechanical structure, maybe the structure diagram of the mechanism that opens here!"

"But Catrina didn't detect the mechanism here. ”

Kitty's words were like a basin of cold water to extinguish Tarrant's ignition of excitement, "Okay, okay, even if it's not a structural diagram, there must be some hint that you didn't find anything from these things on the ground?"

Teammates put on a pensive look.

"Keep going," Catrina said suddenly.

The tone was firm, she must have a clue, Tarrant was secretly happy, strode forward, and on his right hand side another brazier, he lit the brazier, illuminating the thread-like pattern on the ground.

As Tarrant advanced, the brazier on the right side of the wall rose one by one, a total of five, illuminating the right half of the ten-meter-long aisle, and after lighting the fifth, the end also appeared in front of Tarrant, a wall with four horizontal lines.

"Hah!" Tarrant shouted "I knew there must be a mechanism, this place has been sealed", he leaned forward to take a closer look, there were three neat gaps in the wall in front of him, this was a clear sign of movability, it was a device like a movable sliding door, the elves didn't seem to deliberately hide this, according to this speculation, the intention of the maker was to hope that the entrant would choose one of the doors to activate the passageway.

After such a long period of corrosion, they may have rusted to death, Tarrant's left palm lightly pressed the second trapdoor to advance, the wall immediately collapsed slightly, the ancient mechanism was still working, he retreated to the wall and waved his torch, "Guys, here's a multiple-choice question, four trap boxes, guess?"

"What's the penalty for guessing wrong?" Rex asked, ten meters away, "Will the walls close?"

Close?Tarrant patted the sawtooth beside him, in case the worst happens, he probably won't even leave a bone residue, considering this, his sense of humor suddenly diminished, "So what should I choose...... Maybe you can see more by lighting the brazier on the left", he decided to light the brazier on the left as well.

The mage took Kitty's hand and whispered to her, and Kitty shouted to this side, "Tarrant, press the third piece!"

"The third piece?" Tarrant tapped on the third piece in confusion, "Are you sure?"

The mage nodded in the distance.

"Okay, Katrina, I'll vote for you", Tarrant pushed his palms on the third wall, and the flap sounded a "rustle" sound from the inside when it was pushed by an inch or so, and the wall began to shrink automatically, and a rusty iron chain fell out of the recessed part, Tarrant pulled the chain out hard, and the whole wall shook violently, and began to move slowly to the right, and the dust floated up in bursts.

Granular dust obscured the view, and Tarrant coughed back, and when the dust cleared, a black hole appeared in front of him, a smashed door frame.

"Good, guessed right", Tarrant smirked, "Come here, guys." ”

The three of them walked this way.

Tarrant greeted him, "Master, how did you guess it was the third piece?"

"Stupid, I'm not guessing", the mage glanced at Tarrant proudly and disdainfully, "The elves have shown the way. ”

"What?" Tarrant looked at the other two, "Is it different from what the other classes see as mages?"

Rex shook his head numbly, "I haven't thought of the reason yet. ”

"I didn't see the truth because you didn't adjust to the right height. ”

The mage's profound explanation made it even more difficult for Tarrant to understand, "What the hell is going on?"

The lines were a three-dimensional figure, and Rex could see the lines descending step by step, and to me sitting on the ground, they were always in a horizontal line, connected to the third line on the mechanism activation wall. ”

"Ah, I see," Tarrant said contentedly as he walked into the new passageway, "let's see what is here." ”

As the light of the torches reached into the room, Tarrant was shocked by the sight in front of him, the marks of burning everywhere, the entire wall blackened, the messy shelves falling to the floor, and a layer of black powder covering the floor.

"The burning here is much stricter than in the other rooms, and there may have been a lot of combustibles," Tarrant stopped in the doorway and looked in, the room was airtight, there was no exit, and the wounds of violence and barbarism on civilization were everywhere, and he subconsciously resisted entering.

"Look at the ground," Kitty pointed to the corner.

A book, it seems to be a hard cover, Tarrant stood on tiptoe and walked over, reached out and tried to pick it up, but his fingers poked it directly, crushing the cover into several pieces, "Damn!" Tarrant didn't expect the book to be damaged so tightly, he carefully picked up the rest of the book, a few ancient words blurred on it, he turned around and presented it to the mage, "Can you read what is written on it?"

"Error...... Principle ......" the mage said with less confidence, "fault...... It could also be a mistake...... No, no, it's an illusion!
