Prodigiously Amazing Weaponsmith

The magic circle around the entrance is used to open the gate instead!

Moreover, before the magic circle is actually activated, these formation patterns can also play the role of gathering magic energy, raising all the monsters stocked in the deep pool by more than one level, and also playing a very good defensive role.

This design...is really unexpected.

Even Huang Yueli, a genius spiritual weapon master who claims to be a mechanism master, felt deeply inspired.

"The design of this mechanism is too ingenious, but it can only be achieved with the help of the treasures inside the door. Because the magic energy condensed by the treasures inside the door is too strong, if we don't use the outer formations, even Mo Ying and I can't do it." To break the formation with brute force, we can only rely on mechanisms... But, we don't have the key, what should we do?"

Huang Yueli soon realized the problem, and her heart suddenly became heavy.

The operating principle of this mechanism is too simple to say, but because of its simplicity, it is even more difficult to decipher.

As long as there is a key, it can be opened, but they don't have a key...

"This is troublesome. Where can I find the key now? The only way is to find a way to reverse the shape of the key and the pattern engraved on it according to the direction in which the pattern of the magic circle flows, and imitate it as much as possible." Try the same key..."

However, this is easy to say, but difficult to do in practice.

With Huang Yueli's cultivation level, if she randomly finds a piece of metal material, no matter what shape she wants to carve, or how complicated the lines are, she can finish it in just a few breaths.

But the problem is that just having a pattern doesn't mean it can be recognized by the energy tank.

The key's material, weight, pattern, spiritual imprint, etc. are all closely related to whether it can open the door.

It is almost impossible to reproduce it perfectly.

The problem of this material alone cannot be solved.

But now, she has no better way, she can only treat a dead horse as a living horse doctor.

Fortunately, Huang Yueli has always had the habit of hoarding materials in the Tianhuangjue space, so she took out several rough stones from the space on the spot.

Because this mechanism was discovered in the demon mine veins of the demon race, Huang Yueli's first choice of material was of course the few raw demon mine stones dug out on the mountain wall just now.

She frowned and thought for a while, and then deduced several possible key shapes according to the magic circle patterns around the circular gate. Using the strange fire in her hand, she completed several keys within a dozen breaths.

Without any hesitation, she took the keys and stuffed them into the energy tank to test.

It's a pity that her luck is really bad. None of these keys can open the gate of the organ.

On the contrary, two of them resonated with the surrounding circle patterns, and even caused the demonic energy in the pool to fluctuate obviously.

However, this fluctuation did not cause the demonic energy to flow back into the magic circle as Huang Yueli expected. The fluctuation only lasted for a few breaths before regaining its calm, and the bronze gate remained quietly in place. ground, there is no change.

Moreover, although these fluctuations failed to push the gate, they instead attracted the attention of the extremely cold giant octopus!

This ancient ferocious beast had already been completely enraged by Li Moying, fighting with him, it had long forgotten the gate it was guarding.

However, at this moment, it suddenly realized that the situation...something was wrong!
