After a small skirmish, everyone reassessed their respective situations: a few shields were damaged, some people were a little dazed after falling, but otherwise they were fine.

Geralt used his witcher senses to scan the room. Since there was a magic mechanism, there must be something wrong with this room.

Suddenly, the witcher's gaze turned to the back of the statue, and in his vision, there was a hazy light attached to the wall there.

He walked over, raised his hand and cast the [Alder Seal]!

Then the entire wall collapsed, and there was indeed a hidden world behind it.

When everyone stepped forward to observe, they saw another simple and plain passage behind the wall. Its style seemed to be completely different from the ancient elf-style buildings they had seen before.

Obviously, the builder of this passage built his own secret laboratory based on this relic. The gold and silver outside were even placed deliberately just to hide the real treasure inside.

Only now have they truly seen the tip of the iceberg of Thomas Moreau's secret laboratory.

Following the tunnel, the group soon reached the end. At the bend ahead, they saw a huge stone ball two people tall, with a broken skeleton sandwiched between the stone ball and the wall.

"Someone seems to have failed to avoid the trap."

Obviously, the stone ball rolled in from the other side of the passage and smashed the tomb robber against the wall.

Lann stuck his head into the passage and looked inside. There seemed to be a few broken bones and pieces of cloth in the darkness. It seemed that the stone ball had achieved great results and crushed many people.

Geralt went forward to search the corpse and found a parchment, which was surprisingly well preserved.

Lann took the parchment and began to read:

"…Since suspicious people have started to appear outside my lab, I have to take more security measures. I think they are probably just common criminals looking for valuables to steal and have no interest in my research, but it's better to be cautious."

[ILLEGIBLE WRITING]

In addition, I decided to follow the advice of an old engineer acquaintance and use a simple mechanical device to protect the laboratory. In one of the rooms on the corridor leading to the laboratory, I installed a mechanism that can lock and unlock the door, which is operated by pressing four protruding stones high on the wall.

I can open the lock with a simple magic, but ordinary thieves will face two challenges: first, they must notice the four stones, deduce the function of the stones, and then they must find a way to press the stones...

[ILLEGIBLE WORD]"

The parchment seemed to be an experimental diary. Large sections of the handwriting had become blurred and unrecognizable due to the passage of time and improper storage, but the remaining text was also very valuable to Lann and his team.

The name of the owner of this diary is already obvious - Thomas Moreau!

The druid sighed, "They are just a bunch of tomb robbers. They actually found Professor Moreau's magic laboratory. It's a pity that they got in alive but couldn't get out alive."

Lann said to Geralt, "Now it's easy. We will definitely find the secret laboratory by following the places these tomb robbers have walked."

With Geralt's witcher senses, the group searched in the reverse direction of the tomb robber's escape and soon arrived at the edge of a huge underground canyon.

At this time, there was no trace of the ruins of the elven palace around, and it was transformed into the simple architectural style of traditional research warlocks.

The rock walls on both sides were simply chiseled out with a drastic approach. The road was very crowded and even two people could barely walk side by side. If you were not careful, you might fall into the canyon below.

There are some traces of buildings on both sides of the canyon, and there is also a small section of bridge wreckage on each side. It is obvious that the two sides were connected to each other in the past.

Geralt pointed to a small rope tied to a pillar on the edge of the canyon and said, "These tomb robbers did not come in through the same entrance as us. They slid down the rope from the other side and established a small base here."

There are some traces of human life on the ground, including food remains that are about to merge with the dust, braziers and torches that cannot be lit, and temporary constructions that are completely inconsistent with the surrounding architectural style.

Geralt pointed in front of him: "And the purpose of their building a temporary camp here is for this. This is a door."

Geralt pointed to the wall in front of him, where there was a small recessed brick "wall".

If it weren't for the witcher's senses, no normal person would think this was a door.

The druid stepped forward to observe it seriously and commented: "It is indeed an engineering building style from hundreds of years ago. This must be the place."

Sword asked, "How do we get in? How about we pile up the remaining bombs and blow them up?"

The Sword Sergeant's face was shining with excitement. After the battle with the water ghost, he seemed to have developed a strong interest in alchemical bombs. Although he said that this method of attacking the enemy was detrimental to the way of knights, he actually tried every means to find an opportunity to explode.

Lan slapped Sword on the head and scolded him angrily: "We are at the edge of an underground canyon. Who knows if a large-scale explosion will trigger a chain reaction such as a landslide. Don't bomb without my order!"

Then, regardless of the servant who was rubbing his head and nodding, Lann took out Geralt's parchment and scanned the surrounding environment.

This was the scene he had experienced in the game in his previous life. His memory of how many monsters he had encountered and how much treasure he had found might be fuzzy.

After all, no matter how strong a monster is, as long as it has a health bar, it can be cut down in the game; no matter how precious the treasure is, it can only be exchanged for coins and become a string of numbers in the backpack. These are not worth occupying Lan's precious memory.

What really sticks out in my mind are those complicated maze puzzles and escape room procedures. For example, the one in front of me had stumped Lan for more than half an hour.

He once thought that he had to go to the other side of the canyon to find the laboratory instead of opening the damn door in front of him!

"Isn't it written in Professor Moreau's diary?" Lann unfolded the parchment so that everyone could see, "One of the rooms in the laboratory corridor is equipped with a mechanism that can lock and unlock the door. It is operated by pressing four protruding stones high on the wall."

Lann looked around again, and everyone followed his gaze.

Geralt had never thought that the environment described in the diary was here. After he finally connected the contents of the diary with the surrounding environment and consciously looked for "protruding rocks", four places on the rock wall suddenly flashed red light in his witcher senses.

“Found it!”
