Dark underground.

The underground cave, which was originally formed by the dissolution of thousands of years of flowing water, has been converted into part of the ice cellar - and the lowest level - by the Kassel Academy. Named after the place where the three goddesses of fate weave their lifelines, it is the well of annihilation.

The floor is covered with a thick layer of bronze, and deep grooves are sunk into it, growing, spreading, curling, entangled, and stretching in this dark and wide hall, growing from an unknown territory and ending in a circle in the center, like a mythical world tree.

The blue-gray condensate liquid makes up the body of these lines, outlining an infinite number of bizarre symbols.

They are flowing, in this dark and silent place, meditating year after year, insulating from all the erosion of time.

This is a great alchemy array built under the auspices of the Night's Watch, which can block almost a single invasion of external forces, and also forbid the use of all words and spirits. Relying on the characteristics of mercury, the circulation is endless, supporting a huge field that does not require any energy supply at all.

Even if you look at the generations of Nikola Meler, this can be described as a first-class project. Its grandeur is only second to the Mausoleum of Qin Shi Huang.

'With mercury as a hundred rivers and seas, the machine is instilled, with astronomy at the top and geography at the bottom. With mermaid ointment as a candle, those who will not be extinguished will last for a long time'. Such an exaggerated description is Sima Qian's record of the Mausoleum of Qin Shi Huang in the historical records.

With that kind of giant alchemy array alone, it was easy to maintain the immortality of the things in the tomb for thousands of years, and ordinary tomb robbers had no way to start.

Of course, the Academy's alchemy array could not have been built after obtaining the keel, as the time consumed for such a project was completely proportional to its grandeur. As early as the beginning of construction, there was a keel that was conceived to seal the highest grade of the artifact. And now it does.

Jiude Mai quietly stood against the wall, constricting her breath to a minimum.

Thanks to the rigors of the ninja's training, she is able to reconcile her body temperature with most of her surroundings, think without thinking, and breathe at a rate close to once a minute.

In front of her, the world's second alchemy array, she is helpless, but thanks to the information of the boss of Guò, someone who can break it will arrive tonight.

Is there really a 'person' who can break it?

Sakutoku Mai didn't know, because even if she stood up a little straight, she could feel the repulsive force of this alchemy array, as if a huge spirit and dustless place had pressed her directly against the wall, no different from being unable to move.

Tonight, she was also quite surprised when she received her boss's instructions, the alchemy array in the Well of Annihilation was not only famous in the Kassel Academy, but even in the entire half-breed world, everyone with some status had heard of it.

Some call this the peerless cage, or the most withered seal.

Now, however, she heard the sound of light footsteps.

"It's a remarkable achievement, and humanity has been able to expand alchemy to this extent."

In the boundless darkness, she couldn't see the other person's appearance clearly, but with this hoarse and somewhat sexy voice, she could probably tell that it was a woman, and her age was about ......

Thinking of this, Mai smiled silently.

The occupational disease is still strict, just by walking as usual, it is enough to judge that the other party is not a mixed race, and for the dragon king-level storage zài, discussing age is undoubtedly funny.

"It's been a long time, you're really a wolf."

The footsteps continued for some time before ceased, and the intruder probably walked to the edge of the central lake, looking at the keel stored in the cross. Only the sneer still echoed in the empty and lonely hall.

"Uhhh

There was a short soft sound, as if something had been turned on. Then there was a sizzling sound that made the scalp tingle, Jiude Mai frowned, holding her breath for a while, I don't know what tricks that person used, and the mercury in the entire alchemy array was all evaporating.

The liquid in the deep tank reacts with a strange substance, quenching a dark red sheen in the darkness and eventually vaporizing, leaving some kind of corroded trace.

However, one thing that can be concluded is that it is not a scientific method.

"Troublesome Alchemy Array," the man grumbled softly, "I can't find anything knotted, and as a result, I can only use brute force to erase it." ”

The seal that had suppressed this place for many years had been broken, the air had become less dull, and the antiques of the living spirits were noisy, but the gesture of this person was gone.

"Be quiet, or, play some big tunes." Her voice was cold, "Because next, it's time to reunite." ”

'Mercury vapor ......'

Mercer groped in the dark, the air giving him an oppressive feeling, and the dragon's blood part of his body seemed to be completely inactive. The academy has been trained to distinguish mercury vapor, which is highly toxic to dragons and not a good thing for hybrids.

It seems that the well of oblivion is not far away.

He was secretly vigilant, and the fact that pulse perception alone could not be used here was already putting a lot of pressure on him. Alchemy or anything is not his specialty, and in front of this kind of masterpiece, even if he has taken the subject of "Ancient Alchemy Application" seriously, it will not be no different.

If he was discovered by Xia Mi, who was walking in front, because of the excessive movement, he might really have no way out.

But......

Mercer's eyes flashed with a hint of scarlet, completely overpowering the pale gold of the dragon's blood, like a bloodthirsty demon.

He never imagined that there would be so many delicious ...... in the academy's aquarium Nutrient-rich creatures, especially some hybrid subspecies of dragons, provide him with a lot of stunts.

There are quite a few creatures, in fact, he is completely invincible, and he doesn't have to be in the water to almost lose all of his mobility. Fortunately, Xia Mi's ability is really amazing, and he can kill those water overlords in a light way, which also gives him the opportunity to pick up the cheapest.

And now, after another targeted reinforcement, Mercer is more sure about the next action.

After all, the power of the black light virus has become more powerful.

In addition, I have a terrible headache today, and this chapter is really difficult to write. There may be some water, please forgive me. ）
