Her vision was completely dark, and she fumbled to sit up.

During the struggle just now, Lin Wu had lost the flashlight she was holding, so she could only look for a spare flashlight.

But because of falling into the water just now, Lin Wu's backpack was soaked, and most of the things inside were unusable. Only the bag that Bai Jing gave her was waterproof. Lin Wu took out a small flashlight from it and turned it on. The light was weak, but it was enough for Lin Wu to see the surrounding environment clearly.

She was actually on a stone path at the moment, with direct paths on both sides.

The air was relatively humid, and the stone walls were covered with a layer of moss, reflecting a faint cold light. This made Lin Wu wonder if this stone path was under the river, or at least close to it.

There is no secret door in sight. Is it only possible to enter through the passage opened by the mysterious arts? Then the place where the archaeological team members disappeared was here? If so, I wonder if the entrance and exit where Bai Jing and Bai Ning had the accident also need to rely on the mysterious arts, or is it an actual passage.

Thinking of this, Lin Wu propped herself up and stood up. She first checked the things in her backpack, stuffed the still usable ones into the bag Bai Jing gave her, and left the rest where they were to reduce the weight.

Then he looked at himself and found himself soaked. But there was nothing he could do. Lin Wu didn't bring any change of clothes, so he could only make do with it.

She tried her best to wring out the water from her clothes to make herself feel better, and then looked at both sides, both of which were equally quiet and profound.

Lin Wu tried to find any traces of human footsteps, but there was none, so he simply followed his intuition and went left.

The first thing Lin Wu felt in the passage was the chill, which made her sneeze constantly, and she had to keep moving her hands and feet to keep warm. The flashlight could only illuminate a limited area, so Lin Wu kept her spirits up and paid attention to her surroundings as she walked.

Without noticing anything unusual, Lin Wu first realized one thing - she had been walking for more than ten minutes, and the passage seemed to have not changed, as if she had been going around in circles in the same place.

Lin Wu took out a dagger and made a few cuts on the wall to mark each passage he passed. At the same time, he looked at the compass to record the direction and distance he had passed, and drew an invisible map in his mind.

After a while, Lin Wu stopped and frowned as he looked at the familiar mark on the wall that had been left not long ago.

She really hadn't walked out, she just walked around in this area. How could this be? She clearly didn't remember walking the same route again.

Suddenly, Lin Wu wondered, could it be that she couldn't trust what she saw with her eyes? In other words, was she trapped in some kind of illusion caused by a mysterious technique? Thinking of the mysterious technique she experienced when she fell, Lin Wu felt that it was possible, so she bit the wound on her finger and drew a curse seal out of thin air with the blood, and wiped it over her eyes.

When he opened his eyes again, the scene he saw was completely different! There were strands of white light floating in the air, connected to each other to form patterns of magic, spreading in the same direction, looming, and the aura contained was even more profound and exquisite, full of pressure, causing Lin Wu's eyes to hurt after just one glance, and it was difficult to look directly at it.

Lin Wu closed his eyes to relax, then took a step forward and followed.

After a few steps, she stopped in front of a wall, and the flickering lights disappeared into the wall!

Could it be that this wall is just a decoy?

Lin Wu reached out and touched the cool stone wall, then took a few steps back.

According to what she had learned, no matter how powerful the illusion was, it was fake and could not become real. It all depended on whether the person had the courage and determination to believe in it.

Thinking of this, Lin Wu quickly changed her hand gestures and formed a seal on her forehead. A chill instantly appeared in her mind, making her more sober and calm. A layer of vague protective barrier also appeared around her body.

She took a deep breath, rushed forward, and crashed into the stone wall.

At the critical moment, Lin Wu subconsciously closed his eyes.

The expected pain did not appear. Lin Wu staggered a few steps, then immediately stood firm and opened her eyes - she really passed through the stone wall and came to an unfamiliar passage!

The traces of magic were still in the air. Lin Wu calmed himself down and continued walking, passing through the stone wall four or five more times in the same way.

The smoother things went, the more confused Lin Wu became.

Did the people in the archaeological team encounter the same situation? How did they get out? Was there a master in the archaeological team who saw through the mysterious arts here? If not, why didn't she see any signs of other people being trapped when she was circling before?

Not only was there no trace, but it was so quiet here that it seemed as if she was the only one who had been here.

The surface of the stone door was smooth and dull, but there was no carving or lock on it. But Lin Wu saw that the source of the magic was gathered on the stone door.

Lin Wu walked forward and pushed the door, but it didn't budge.

Could this stone door also be a trick? Lin Wu said he would give it a try and he bumped into the stone door directly. But it turned out to be a solid and hard stone door. Not only did Lin Wu not get through, he was also stunned for a while due to the collision.

She had no choice but to feel around the door and its surroundings. She found no mechanism and initially determined that this stone door would also require the use of mystical arts to open.

But if this is not an illusion, what other mysterious arts could it be? To crack it, one must first know what mysterious arts were cast upon it.

As Lin Wu was thinking, she glanced at the connected points of view in the air, and suddenly realized that the stone walls she had passed through before were an illusion, but that did not mean that the light spots that led her here were also traces of illusions.

In fact, she saw many forks in the road after passing through the stone wall. Not only the road she was walking on had traces of magic, but other roads also had traces of magic. And the traces of magic on these roads had something in common, for example, they all originated from behind this door.

Therefore, the most important location here is behind this stone gate, which is the center connecting all directions. It is not easy for such a huge spell to completely hide its weaknesses, and there must be traces to follow.

Lin Wu squatted down and used the tip of the knife to draw all the magic patterns he had seen on the ground. He muttered something to himself, trying to find the operating rules and then deduce the solution based on what he had learned.

This took Lin Wu half an hour.

After all, hard work pays off, Lin Wu really figured it out! She immediately stood up, drew a line on the palm of her hand, and formed a seal with the blood spilling out, hitting the deep magic hidden in the stone door, forcing it to appear on the door. The huge round magic disk slowly floated and rotated, becoming clearer and clearer.

Lin Wu quickly found its weakness and destroyed its blood with one palm.

In an instant, the stone door burst open as the magic collapsed, and the scene inside came into view little by little.

Lin Wu unexpectedly discovered that although there were such obscure and complicated magic protection outside, there was nothing incredible and shocking inside.

There was only a stone room inside, not very big, only about 30 square meters. And it was empty, except for a rectangular stone platform in the middle, and on top of it there was something of the same size, which looked a bit like... a coffin... a coffin? ?

“Is this a tomb?”

Lin Wu rubbed his eyes and looked again, it was still the same, and he immediately became alert.

According to her past experience, if there is such a coffin in such a secret place with layers of protection to prevent outsiders from entering, the coffin is likely to contain something very dangerous.

But her tattoo did not come out to remind her, which meant that the situation inside was still within her control.

After hesitating for a moment, Lin Wu finally decided to go in.

As he approached, Lin Wu shivered with cold, as if there was a thousand-year-old ice in the stone chamber, and there were gusts of freezing wind.

After approaching and holding up the flashlight to look, Lin Wu was stunned.

The coffin had no lid, so she could see directly inside. The first thing she noticed was the light reflected from the coffin wall. There were actually ice cubes. It couldn't be seen from the outside because the coffin was divided into two layers. The inner layer was made of ice, and the outer layer was made of black unknown material to make a coffin next to the ice coffin.

And inside the ice coffin lay a man in a cloth robe. He was tall and straight, and wore a half mask that covered 80% of his face.

Although his appearance could not be seen, the other person's pair of slightly closed narrow phoenix eyes, thin red lips and chin all had clear and sharp lines, which made him look quite cold, indicating that he was probably a very young man.

However, Lin Wu was only surprised at this moment.

——This man has not decayed and looks as lifelike as when he was alive?!
