Chapter 81 What key, open this lock?!

Several wolves showed a very excited look! From Brad's vague inference about the Twin Lakes, to the surface of the cave, to finally finding this deeply disguised metal mechanism, they took a lot of effort!

In the eyes of several people who have experienced the whole day's rush and two fierce battles and have not even rested in the middle of the night, this kind of joy and worry is really exciting!

Isabella stepped forward without hesitation and carefully studied the concentric metal disk attached to the stone wall! Several other people tacitly took a few steps back, and it would be better to hand over such professional work to professionals!

Brad watched nervously as Isabella took out one strange thing after another and checked the metal mechanism. He knew that since there was such a thing, it clearly proved that this place was not formed naturally!

Dive such a large cave, introduce the lake, set up a light source... Behind these seemingly unreasonable behaviors, there must be a pair of invisible and powerful hands to complete such a masterpiece!

Maybe it is also a dangerous conspiracy to wait for them in front of the unknown!!

Just as Brad was thinking about himself, suddenly the corners of his clothes were gently pulled a few times. Brad suddenly turned around. Not surprisingly, the big eyes that looked at him innocently came from his innocent, cute, impulsive and straightforward fiancee - Xia Fei!

"Brother Bu...Yuan Lai," Xia Fei whispered with some embarrassment. It seemed that she was not used to not revealing Brad's true identity in front of Isabella: "I don't understand why Gu Lie wrapped himself into a big steamed bun just now and could find the mechanism? Does that mechanism need to be touched by magic? If I use my red lotus, can I find the same mechanism?!!"

Before she finished speaking, Xia Fei's expression became like a good baby who couldn't be better. Her big eyes blinked and blinked, making Brad couldn't help but get the girl's short hair!

"Fool, he is not a steamed bun! It's a very subtle large range of thunder attribute magic!" Brad smiled and explained patiently, "You, a talented girl, can't have learned it. Stone is an insulator, and metal is a conductor!" Now that it has been determined that the mechanism you are looking for is metal, as long as you use electric current to test it on a large scale, you will definitely find the position of the mechanism because of the conductivity of the metal!"

"Oh............" Xia Fei nodded as if she didn't understand, looked up in a daze and asked, "So, my Honglianyan is useless for this organ, right?"

She showed a little regretful look, took a sip and muttered, "The blind cat met a dead mouse..."

Brad couldn't help sweating coldly. This guy is not interested in these physical knowledge at all, but he is not convinced that Gu Lie can find a mechanism! This is too competitive!

As Brad was searching for words to deal with Xia Fei, Isabella, who had been immersed in the research institution, suddenly raised her head and said mindlessly, "That's not necessarily!"

"Oh? ~" Several people answered together. Obviously, they didn't know why Isabella meant this word.

"I mean, your Honglianyan may really have some effect on this mechanism!" Isabella turned around and said calmly.

"Really?!!" Xia Fei jumped up excitedly! It seems that this little girl cares more about winning or losing than Brad thought!

Isabella nodded, put away the strange instrument in her hand and said, "If my exploration is not wrong, this mechanism is likely to be driven by magic!" I just tried it slightly with various magic elements, and there is no response to this damn thing. I guess it probably needs to reach a certain strength to touch the mechanism!"

"So..." Isabella paused and continued, "I suggest that everyone try this broken circle with magic above the primary level. Maybe if you get it right, you can open the mechanism!"

"Hu..."

Before several people made a sound of peace, a hot wave had been released around. Obviously, the impatient Xia Fei was ready to go!

Brad didn't have time to remind Xia Fei to pay attention to the strength of the flame, lest the hot red lotus directly turn the mechanism into iron water, and the palm-sized, crystal clear red lotus has taken shape!

Isabella saw that the situation was not good, so she ran away quickly! Just as she staggered her figure, Honglian had already urged, and the target went straight to the metal concentric ring disguised as a stone wall!

The speed of the red lotus is not too fast, but as it moves forward, huge heat waves continue to hit several people! Although this crystal clear red mini lotus does not look dazzling, no one can doubt that it contains enough horrible energy to burn the sky and the earth!

Soon, the red lotus traveled to the edge of the stone wall, and saw Xia Fei's slender hand pointing, and the palm-sized lotus began to spin! Every time it rotates, a small lotus petal falls from the flower tray and falls straight up to the metal mechanism!

So that's it! Brad suddenly realized!

Unexpectedly, the continuous output of Honglian is used to solve the damage that may be caused to the organ due to the too much energy of the red lotus! Look at the beautiful rotation and stable release of energy of Honglianyan, which has been out of the category of attack. It is simply a magical performance art full of beauty!

Xia Fei is indeed a rare genius girl in the demon world for 50 years! Now that the average strength of the team has improved, how can she stay still! Looking at her skillful control techniques and Honglian's leisurely and slow movement, it is obvious that during this period, her control and perception of magical elements have been greatly improved!

The red lotus petals fell, and with the hissing sound of burning, even the dark gray stone wall darkly revealed a red color charm. However, the metal ring has not changed at all, not even a trace of color change!

Xia Fei saw that her best red lotus did not work, and bit her lower lip fiercely. There was a sharp mark on the soft lips of the tiger teeth. When her fingertips turned, most of the flame petals that had fallen suddenly stopped rotating, paused for a moment, and rushed straight up to the metal mechanism!

It seems that continuous output is useless. She wants to activate the mechanism directly with high-intensity flame magic!

"zi............"

The hot red lotus flame was branded on the stone wall, making a harsh burning sound! Everyone stared at the burning red stone wall, and the metal ring painted dark gray remained unchanged!

"I don't believe it!!!" Xia Fei frowned and waited for a move. Judging from the strong magic fluctuation from her body, she was going to be serious!

Brad quickly stopped this impulsive girl. You know, the guy who can open up such a large cave and introduce the lake is definitely not a good match!

They also expect to open this mechanism to get the hidden treasures of their predecessors! If it is destroyed by this female Tyrannosaurus Rex, not to mention that Isabella will be distressed, others will also be extremely disappointed!

"Okay~" Brad softly comforted the angry girl: "Don't worry, Isabella only said that magic can touch the mechanism, but didn't say it must be flame magic. Why are you so hard? Let everyone try it later! I promise that if anyone doesn't care, no matter how you destroy your nature, okay?!"

If it weren't for the person who said this to be her fiance, Xia Fei would never give up easily, but Brad was his own crush, and secondly, it was also well-founded. Xia Fei had to demobilize the gathered magic elements, stamped her feet unconvincedly and walked away!

At this time, the stone wall is still red spontaneously. Several people are afraid that the intersection of water and fire may cause the stone wall to collapse. They dare not let Meru use water magic. They can only be tested by the Wind Wolf King and Isabella with wind and wood magic successively.

It is frustrating that these two series of magics still have not changed the mechanism at all... At this time, including the thunder attribute magic used by Gu Lie at the beginning, several series of magic failed to open the mechanism, and several people couldn't help but become a little impatient!

Finally, the stone wall gradually cooled down. Meru silently stepped forward with one move with both hands. The lively water dragon appeared on her side again. Her wrist was slightly wrong, and the sound of water suddenly rose, and the water dragon had rushed to the stone wall!

"Wan! Wow! ......”

The sound of water is constantly stirring. Obviously, the momentum of the water dragon is also very good. When the water mist dissipates, several people are staring at it. The stone wall is still standing, and the organs are still the same!

Water magic has also been invalid!
