...... "Well, he knows that this thousand gold coins are not so easy to earn."

Hey, North Prince, Oriental Son, West Prince, come back quickly!

After a rough explanation, Nan Qingxue immediately set off for the east side of the border, and now she couldn't wait to check the hidden magic circle she had discovered last time.

What secrets are hidden in there?

She had a hunch that after cracking that magic circle, she would be one step closer to the demon cultivation experiment.

"After breaking the magic circle this time, it is very likely that you will directly face the powerful force behind you, you have to be mentally prepared." Bai Jue's expression was solemn.

Nan Qingxue nodded, before this, she was mentally prepared.

To be able to create such a large-scale experiment and quietly take away a city overnight, the strength of the other party will definitely be terrifying.

Bai Jue flew out and rushed to the eastern part of the border with Nan Qingxue to find the tree they had stayed at last time.

Nan Qingxue looked down condescendingly, during the day, there was nothing unusual here, in order not to startle the snake, she still planned to do it at night.

She leaned against the tree and closed her eyes.

When the last glimmer of light on the earth was swallowed up, Nan Qingxue immediately jumped down and used her spiritual power to probe the talisman array.

Now that she has been promoted to the imperial level rune cultivator, it is very easy to see through this rune array.

She probed the words in her mouth, and immediately found the entrance to the hidden circle.

"The person who arranged the magic circle does have some doorways." Nan Qingxue frowned slightly, this magic circle is very strange, there are many entrances, but only one is true, and below the other entrances, there is also a small teleportation array.

What is the purpose of the other party's this?

Placing a small circle under the circle is likely to disrupt the effect of the sigil.

"The other party should be very confident in their own strength." Hearing her thoughts, Bai Jue spoke lightly.

Nan Qingxue nodded, and there was no other explanation now.

Nan Qingxue found the right intersection, ate a pill of breath, and jumped directly from the entrance.

There's still a lot of space underground, and there's a fork in the road everywhere, so you can't see the bottom at a glance.

She didn't dare to act rashly, carefully hid her breath, and asked Bai Jue to help.

"Master, can you draw a topographical map of this area?"

If you can know the route, the rest of the matter will be much easier.

Bai Jue nodded, and immediately covered the place with spiritual power, and an image was immediately imprinted in his mind.

Bai Jue drew the map, looking at the intricate intersection, Nan Qingxue frowned slightly.

"The other party is a mouse, how can there be so many messy forks in the road."

"A lot of the forks in the road are just tricks, so I drew them by the way to make it easier for you to see it clearly."

Nan Qingxue nodded, on that map, there are still many places marked with circles.

"What are these?" She pointed to the circles and said strangely.

"There are a lot of demon cultivators and ordinary people in these places, I'm afraid they are being locked up here for experiments." Bai Jue's tone was solemn, he didn't expect that their place was actually an experimental base.

Nan Qingxue was also shocked in her heart, no wonder the other party was so cautious, it turned out that the place they came from was the nest of those experiments.

However, seeing that the map was densely packed with circles, Nan Qingxue was also a little shocked in her heart.

How many people did the other party arrest, such a large-scale experiment, must sacrifice a lot of people.

Those people are demons, Nan Qingxue clenched her hands, if she had the opportunity, she must kill those demons with her own hands.

Not only that, but now there is an even more terrifying thing, if she doesn't stop this experiment, the entire continent will be destroyed at the hands of monster-like experimenters.

Nan Qingxue pasted an invisibility talisman, hid her figure, and roughly walked along the map, imprinting the terrain in her mind.

There was a stone door in many places, and she secretly pushed one open, and inside was an experimental base.

In the corner, there are quite a few corpses.

Each corpse had a hideous face and looked a little scary.

There was a sudden sound outside, and Nan Qingxue hurriedly closed the door.

There didn't seem to be anyone here, and Nan Qingxue was relieved when she heard footsteps enter a stone gate next to her.

Surveying the lab, she saw that it was full of jars and jars of strangely colored potions, and an unpleasant smell emanating from the air.

Nan Qingxue took out a few small porcelain bottles and took a little bit of the contents of those bottles and jars.

When she returns, she must find out what the mystery is.

"These things smell strange, I seem to have smelled them somewhere, but I can't remember them all of a sudden." Bai Jue looked at those things and frowned slightly.

Nan Qingxue opened her mouth and was about to speak, when heavy footsteps suddenly came from outside.

The footsteps finally stopped at her door, and Nan Qingxue's heart immediately lifted, the time for her invisibility talisman had come, and if the other party came in at this time, she would definitely be found.

"Hide on it."

Bai Jue suddenly reminded.

Nan Qingxue looked up, only to find that there was a cave on it, she immediately jumped on it, there were scratches around it, it should be something that she had let go before.

But she can't do that much now.

Just as she hid, the door opened from the outside.

An old man in a black cloak walked in, the old man was thin, his clothes were loosely draped over him, like a skull frame, his eyes bulged out, his skin was chapped, and he looked indescribably weird.

The old man walked directly to the experimental table, Nan Qingxue stared at the experimental table tightly, after she took the things before, they were all placed back in their original positions.

The other party shouldn't be able to see it.

"I'm afraid things are not going well." Bai Jue suddenly opened his mouth in a low voice, looking at the old man's eyes flashing.

I don't know why, when she heard him say this, Nan Qingxue suddenly felt a little nervous.

Even Bai Jue said so, I'm afraid things are really a bit troublesome.

"Did I just ignore something?"

Nan Qingxue spoke quietly, her eyes staring closely at the old man's actions.

When the old man's hand just touched those bottles and cans, he was suddenly stunned, and he looked around vigilantly, his eyes sharp and vicious.

Nan Qingxue felt that the temperature around her was much lower, and she leaned inside, worried about being discovered by him.

Did she really overlook some detail just now? He found out?!
