Left or right, Long Zehao stood on a three-way intersection, looking at the two passages that appeared in front of him and pondering.

After thinking about it in his heart, Long Zehao finally chose the passage on the left.

I don't know if it's the right choice or other reasons, after entering the passage on the left, Long Zehao didn't encounter any traps after advancing for a certain distance.

After thinking about it for a while, he sent a team of Jiaolong to the right passage to scout together to see how the passage on the right was.

After waiting for a few minutes, Jiaolong came over to report that they had advanced a distance of more than a hundred meters, and determined that the passage on the right was also unorganized.

Long Zehao nodded to indicate that after he knew, he continued to advance with his troops, and as for Jiaolong, who went to the right passage to investigate, he let them continue to scout the situation behind the right passage.

When he was advancing, Long Zehao had never encountered traps or other mechanisms behind the passage, and had always come to a door safely.

Seeing the eye-catching magic aura on the door, under the vision of detecting magic, Long Zehao had only one thought in his heart: the next one is busy.

Because under the field of vision of detecting magic, the magic aura on the door was as dazzling as the sun's rays, and it was obvious that the magic on the door was added by a high-level wizard.

"Magic dispel", a dispel spell hit the door, Long Zehao saw that the magic aura on the door was only a little dim, the effect was weak, and it failed.

The direct magic attack, but after the attack spell hit the door, there was not even a little splash, and the attack magic dissipated directly when it hit the door, and the defensive magic was obviously arranged on this door, and it failed again.

As for directly going up and pushing the door and sliding the door, these have no effect, and the door of the secret room does not move, and it has no effect at all.

After changing several methods one after another, Long Zehao finally chose the spell of magic dispelling, which at least can see a little effect.

It's just that in the end, Long Zehao's forehead has begun to sweat, and when the magic dispersal scrolls he brought are about to run out, the magic aura on the door is still there, and the magic on this door is still not completely dispelled.

"Hum", as if a voice appeared in his ears, after Long Zehao used the penultimate magic to disperse the scroll, the magic aura on the door finally disappeared and could not be seen.

Wiping the cold sweat on his head, Long Zehao took out the door opening scroll.

It uses the first-order magic door opening technique, because the physical lock of this magic door is generally relatively simple, and basically the first-order door opening technique can be opened. Moreover, the first-order magic scroll is also relatively cheap, even if it can't be opened, it won't be much to waste a loss.

Long Zehao injected magic power into the magic scroll of the door opening technique, activated the spells stored in the magic scroll, and used it against the closed door.

With a "click", the lock of this door was opened under the spell of the door opening technique.

After the door was opened, there was a huge laboratory in front of Long Zehao, and the test bench was neatly placed with test utensils and various test drugs.

Around the room are a number of test specimens, containing a variety of animals, some of which are humanoids. Obviously, this laboratory is not conducting those ordinary experiments.

On the right, there is a passage that leads to an underground cell, which is made of steel, with all the handcuffs and leg irons, but there are no creatures inside.

On the left side of the laboratory is the place where the test utensils and test drugs are stored.

On the opposite side of the entrance door are two doors, one on the left and one on the right, with a lounge on the left. The door on the right was locked, fortunately it was not a magic secret door, and after Long Zehao used a magic scroll of the door opening technique, the door was directly opened.

It's just that the way this door opens is different from the previous ones, it is stretched left and right.

When the door opened, what appeared in front of Long Zehao was a shaft.

After observation, Long Ze determined that this was a magical version of the elevator, with formation patterns arranged on the four walls of the shaft. However, now the formation pattern has been damaged, and the bridge compartment in the shaft has also crashed under the shaft.

Here in the laboratory, Long Zehao has already searched, except for those experimental utensils, there are no other things that are too valuable, and no experimental records have been found here, so he handed over the rest of the things to Ao Youlan to pack up.

In terms of vertical descent, the dragon is not good at it, and when he goes down the shaft, Long Zehao is carried down by the winged man.

After descending to the bottom of the shaft, the door of the elevator shaft was opened again using the door opening technique.

Illuminated by magic lamps, follow the passage behind the elevator doors into a lobby.

Standing at the entrance of the hall, the first thing Long Zehao saw was a large number of crystal containers, which were soaked in various strange-shaped creatures.

Long Zehao recognized the function of these crystal containers, which were a kind of culture vessels, and it was clear that this underground laboratory was conducting experiments on the human body.

And among these crystal containers, Long Zehao saw a creature that was very similar to those evil aberrations that had been destroyed in the previous battle in the castle.

I don't know if those aberrants in the wizard's castle escaped from this laboratory, Long Zehao thought when he saw the aberrations in the petri dish.

However, when I saw the crystal vessels in this laboratory, they were all in good condition, and there was no damage inside. Moreover, there are no evil objects in this underground passage, and the door of the laboratory is also intact, so I don't think I came out of here.

The reason why the personnel in this wizard castle were infected and mutated into aberrations should have been caused by other reasons, or leaked from somewhere else. And the most likely of them is the wizard tower where powerful evil things appeared later, Long Zehao thought.

Some of these crystal containers have failed, and the cultivated creatures inside have also completely died, and those crystal containers that are still in effect, but because of the barrier of the container, Long Zehao cannot identify the situation of the creatures inside.

After reading it, Long Zehao lost interest in these culture vessels and the creatures inside, and walked through the hall to the back, where the operating room, the rest room, the data storage room, and so on.

In the data storage room, Long Zehao found a large number of experimental records, but Long Zehao was not very interested in these experimental materials on the human body, and he did not want to develop in this direction.

After a brief flip through the pages, he collected all the experimental materials, he didn't need them himself, but it didn't mean that others weren't interested, he just took these materials out and sold them to other students.

As for the leakage of experiments in the real world after other students bought them, causing other personnel to also be infected and mutated into evil things, Long Zehao is not worried.

First, it is because in this unknown number of years, the player has brought out a lot of information from the game world, and there are many more evil and dangerous materials than the information he has obtained now.

Second, there are rules in the Cosmic Alliance, and some of these experiments are restricted. They are no longer allowed to conduct experiments on a planet where people live, and they need to report before they can conduct restricted experiments.
