The magic circle outside the entrance is used to open the door!
Moreover, before the magic circle is actually activated, these formation patterns can also play a role in gathering demonic energy, raising all the monsters in the deep pool to 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 calls himself a master of mechanisms, felt deeply inspired.
"The design of this mechanism is so clever, 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, even Mo Ying and I can't do it without the help of peripheral formations. To break the formation with brute force, we can only use mechanisms... But we don’t have the key, what can we do?”
Huang Yueli quickly realized the problem, and her heart suddenly became heavy.
The operating principle of this mechanism is too simple to say, but precisely because of its simplicity, it is more difficult to crack.
As long as they have a key, they can open it, but they don't have the key...
"This is troublesome. Where can I find the key now? The only way is to find a way to reversely deduce the shape of the key and the patterns engraved on it according to the direction of the pattern of the magic circle, and imitate it as much as possible. Let’s try the same key..."
However, this is easy to say, but extremely difficult to do.
With Huang Yueli's level of cultivation, he could find a piece of metal and carve it into whatever shape he wanted, or how complex the patterns were, and he could do it in just a few breaths.
But the problem is, just because there are array patterns, it doesn't mean that they 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 copy it perfectly.
This material problem alone cannot be solved.
But now, she has no better way and can only treat a dead horse as a living horse doctor.
Fortunately, Huang Yueli had always had the habit of hoarding materials in Tianhuangjue's space, so he took out several rough stones from the space on the spot.
Because this mechanism was discovered in the demonic ore veins of the demon clan, Huang Yueli's first choice of materials was, of course, the few rough demonic ore 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 array patterns on the outside of the circular door. Using the strange fire in her hand, she completed several keys in a dozen breaths.
She didn't hesitate at all. She took the keys and stuffed them into the energy tanks one by one to test.
Unfortunately, her luck was really bad. None of these keys could open the door of the mechanism.
However, two of them resonated slightly with the surrounding magic array patterns, and even caused obvious fluctuations in the demonic energy in the pool.
However, this fluctuation did not cause the demonic energy to flow back into the magic circle as Huang Yueli had expected. The fluctuation only lasted for a few breaths before calmness was restored again, and the bronze door remained silently in place. There is no change at all.
Moreover, although these fluctuations failed to push the door, they attracted the attention of the extremely cold giant octopus!
This ancient ferocious beast had been completely angered by Li Moying and was fighting with him. He had already forgotten the gate he was guarding.
However, at this moment, it suddenly realized that something... was wrong!
