"Marx! I think... I have the keys to the treasure!"

Seeing that Marx was about to take everyone home, Luo Xiaotian no longer considered whether it would be too abrupt to take out the key now.

"Really! Let me see... It's like a key, at least the right shape and size! Where did you come from?"

Everyone's attention, including some of the mercenaries, was focused on Luo Xiaotian, if the key was right, he wouldn't run in vain today.

"Hmm, I'm going to say that you picked it up on the way here, will you believe it?"

“...... Now that we have the key, let's see if we can open the entrance to the treasure!"

Luo Xiaotian handed the diamond-shaped key to the mercenary who was still hanging on the tree, and the mercenary rushed forward with the patterned side, inserted it and turned it slightly.

With a "click-click" sound, part of the bark on the trunk slowly shifts away, revealing a dark entrance.

"Is it really the key, Helen, where did you get it?"

"I picked it up in the lake at school, I don't know who threw it in, I looked at it and put it away. ”

"It's really beautiful, it looks like it's made of crystal!"

Taking advantage of the fact that the hole in the trunk was still completely open, Luo Xiaotian discussed the beautiful crystal with Helen and Nina, and gradually changed from crystal to discussing gems, corals and pearls, and Luo Xiaotian, who couldn't keep up with the rhythm, had to lose.

It is said that in the middle of the distant ocean buried a palace of the god of the sea, which was built in the middle of a whole stunningly large coral, covered with precious stones and pearls.

The sound of "click" finally stopped, and the dark hole silenced everyone present. Looking inside from the opening, there is a staircase that leads downward, and because there is no light inside, it is difficult to see how deep it is.

"Master Karl, don't you want to go in today? It seems that this is not an ordinary buried treasure, but more like a secret laboratory established by an ancient mage. I recommend organizing a professional expedition to get in again, as it's hard to know exactly what's down there. ”

"Albert, how do you know this is a lab? This is obviously a treasure map, I don't think a lab needs to map its location with a map, and besides, this treasure map is definitely not that old that year, it is only two hundred years at most, otherwise it would have lost its effect a long time ago. ”

Perhaps in order to strengthen the conviction of his fellow travelers, Marx explained his ideas and rationale in great detail.

"I can't prove it, but my friend told me that ancient magicians preferred to build their secret laboratories deep underground, and then set up safety devices that only they could open. ”

"I don't see any safety devices, don't worry, Albert, even the ancient magician's laboratory has passed at least five thousand years, do you think what can be left in it?"

“... Okay, Master Karl, at least let's be prepared to enter in case we go?"

"No problem, I trust your professionalism. Let's rest in place for a while, and when we go in, follow the people next to you, and don't get separated!"

Luo Xiaotian didn't plan to persuade Marx, looking at their high spirits, he didn't think he could persuade them. However, at least protect Nina and Helen around you, after all, Nina and the mermaid princess Helen are basically brought out by themselves, and they have this responsibility.

Although Luo Xiaotian was very suspicious of who was protecting whom. One of them could use the magic of the Zero Ring, and the other had not seen her do it, but at least the magic of the One Ring was fine. Taking the key handed over by the mercenary, Luo Xiaotian put it in his pocket casually.

"Illumination!"

After resting for a while, everyone walked towards the entrance under the leadership of Marx, and a luminous light spell illuminated the ground within ten meters of the front and back, and the mercenaries who were good at finding and cracking traps slowly advanced within the range of the light spell ahead. A thick layer of dust covered the entire staircase, and everyone had to walk as lightly as they could when going down, otherwise the dust that would permeate the entire passage would be enough to disgrace everyone.

Speaking of which, Zero Ring's Light Technique is exactly the same as the Light God Cult's Holy Light Technique, and in comparison, the Holy Light Technique has a better effect on restraining the undead.

The long staircase became more and more secluded as it descended, and everyone seemed to be infected by the atmosphere, just walking silently, observing the unchanging layer of walls around it, and the hemispherical grooves that appeared in the walls from time to time.

Marx made a gesture to stop, and as far as the eye could see, a brown door had brought the long staircase to its end. I don't know how deep the ground is now, but Luo Xiaotian knows that there must be some kind of ventilation device here, although there is no wind, but there is no feeling of lack of oxygen due to the closure and depth.

The mercenary at the front cautiously walked to the door, and after checking that everything was free of mechanisms, the door was pushed open.

The door is unlocked.

Two new rooms appeared behind the door, and what was inside was only known after entering it.

Opening the room on the left, the breeze stirred up a thick layer of dust on the floor when it was opened, and it was not until the dust fell back that the group entered the room.

"It really looks like a laboratory, and you can see these metal shelves, where test tubes and other lab tools are placed. It's a pity that only these stone platforms and metal frames are left, and the time is too long. ”

The lab wasn't too big, and most of the stuff had decayed and disappeared, turning into dust all over the floor. Maybe the things that used to exist in this laboratory were valuable experiments, or there were materials about the study of ancient magic, but unfortunately, nothing can be seen now.

"These metal racks may have some value, and they haven't rotted or even rusted after all this time. ”

Marx handed a few metal racks to the people behind them to put them away, Luo Xiaotian also got one, he didn't have any expectations for Marx's treasure map before, but he didn't expect that there would still be a harvest, even if he didn't know what the metal frame was made of.

"Let's go to another room. ”

After carefully examining it to make sure there was nothing left, the group made their way to the room on the other side.

Opening the door, it seemed to be a large hall, and Marx's light technique could only illuminate the space in the vicinity, and some large outlines could be faintly visible from further afield.

Luo Xiaotian was also observing this left and right, and suddenly found a button on the wall near the door, and he pressed it without thinking about it.

After pressing it, he remembered that this was no longer the modern city he had lived in, and the switch installed in the door was not necessarily connected to a light bulb.

There are no light bulbs here either.

As soon as the light came, the magic lamp that suddenly lit up made everyone's eyes squint, Luo Xiaotian didn't light the bulb, but lit the magic lamp.

Ronald ?... Next time, will you say it in advance? And don't press the button when you see it, what if it's a trap?"

"Uh, I'm used to it, I'm sorry!"

After getting used to it for a while, they finally saw what the behemoths in the distance were.

It was as if entering a museum of Warcraft, with a huge skeleton standing in the hall, two empty eyes staring at nowhere. There are many such skeletal specimens, some of which have long tailbones, some have tusks, and some have wings.

The others, the "lifelike" specimens of Warcraft soaked in huge glass jars, some of them still maintained their hideous expressions, as if they were staring viciously at this group of invading uninvited guests.

"Oh! it's disgusting!"

Nina, who was disgusted, couldn't help but grab Luo Xiaotian's robe.

This hall is full of specimens like this, and importantly, it is full of huge magical beasts, and you can see from the size of the body how dangerous these magical beasts were during their lifetime.

Luo Xiaotian had a few questions, first of all, if this was the laboratory of an ancient magician, then it was really a very strange thing that the magic lamp that had been placed for at least five thousand years still had energy, and it could work smoothly.

Second, how did such a huge beast get from the original passage into the underground, or was there another passage elsewhere?

Thirdly, what did the magician who had made so many specimens of Warcraft want to do with only a small laboratory that is less than one-tenth the area of this hall?

Finally, except for the sharp-beaked pterodactyl with wings in the glass circle, the other specimens here have not been seen in the textbooks for the identification of magical beasts.

"Marx? I think that's all for today, right? As you can see, there's nothing noteworthy here, there's no treasure at all, and I'm afraid your map isn't a treasure map. ”

"Hmm... It seems that so, then, we are... Wait Ronald, there's another door there!"

There is also a door near the corner of the hall, which will be blocked by these huge specimens if you don't go inside.

"Open this door, and we'll go back!

Looking at Marx's eager expression, Luo Xiaotian shrugged his shoulders, and was ready, he always felt that it was not easy behind the door.

Unlike the other doors, this one is made up of two closed stones, which slowly open to both sides when the button on the side of the door is pressed.

Does it look like an elevator?

Inside, the room was small, with words in ancient languages carved into the walls around it.

"I'll see, 'Where did we come from, where are we going, will we be the next time we will make a choice?'... What do you mean?"

After reading the words on the wall, Marx looked at each other with everyone.

Luo Xiaotian always felt that this sentence was familiar.

Some of them were still admiring the huge specimens in the hall outside, but only some of the mercenaries and Max Roy entered the small room and saw the writing on the walls.

Suddenly, the stone gate closed inward without warning, and compared to the slow way it opened, one wondered if it was the same stone door.

No one had time to get out, and the mercenaries at the door tried to open the closed stone door with their hands, but it didn't work.

"Master Karl?what now?!"

"I... I don't know..."

A terrified Marx could only shake his head mechanically, feeling that he might have made a wrong decision.

A rumbling sound sounded, and a strong sense of weightlessness shook everyone who had never tried this feeling before.

Luo Xiaotian finally confirmed that this was indeed an elevator, as if it were fake.
