It is impossible to have no mechanism, in which case there is no way to open it. Yuan Tian had also cracked the mechanism in the trial secret realm and the realm of inaction before, and the most rare mechanism in the trial secret realm was cracked by the fairy flute's junior brother, and Yuan Tian was mainly studying on the side at that time.

But when Yuan Tian entered the formation alley when he was in the realm of inaction, he broke all the way, especially the mechanism formation on the last wall was very complicated, and he and Fang Yin finally broke through through the transmission notes while communicating and cracking it.

"Poof!"

Yuan Tian first tried to poke a sword qi at the copper gate, and he didn't use the flying sword to poke his finger directly.

Cut! Obviously disdainful of this behavior plain girl of Yuantian, if this copper door can be poked open with a finger, can you still call him. No matter how strong the palace master's strength is, he can't break through this copper gate. Why is this foreign man so shameless, even if he wants to attack, he at least shows some real skills, and he only pokes a finger.

Of course, one finger can't poke open this copper gate, but in fact, Yuan Tian is doing a test. His fingers constantly emitted sword qi and the speed was very even, but each blow was neither slow nor heavy, at this time, even the Su Su girl could see that she was trying something.

The reason why Yuantian did this was actually to test the thickness and structure of the door. Although he can't pierce the copper gate, the thickness of the copper gate can be estimated according to the strength of the rebound. Even if the estimation is not accurate enough, at least it is possible to know where it is thicker and where it is thinner, so that the structure is different.

He smiled slightly when all the doors had been poked all over by Gentian, because he had found that different place. Yuan Tian drew a frame on the door, and within that range was the place where the copper gate was different.

What does this mean? The palace master and the Su Su girl didn't understand what Yuan Tian was doing, and the next poke seemed to be testing something, and now they suddenly drew a frame on the door, could it be that they found something. But the copper door is flat and neat, and you can't see anything at all, and there is no knocker or mechanism to draw a frame.

Then Yuan Tian began to pour spiritual power into that frame, of course, his spiritual power was no longer ordinary spiritual power, but the kind of energy that was fused. But it doesn't matter, it's a test to see if anything changes when the energy is injected.

After some testing, it was found that this method was ineffective, and Yuan Tian began to put spirit stones in that frame again, and it didn't take long for him to test all the first-order, second-order, and third-order spirit stones, but there was still no response.

"Do you need to try it with fairy stones?"

Just when Gentian was about to change his method, the palace master, who had been observing from the side, suddenly spoke. As soon as she said this, Yuan Tian felt that there was really some truth. With such a powerful Thousand Machine Valley, maybe it needs something more advanced than the third-order spirit stone, that is, the immortal stone, to open the mechanism.

However, Yuan Tian's heart couldn't help but sour, he got a piece of immortal stone after mixing it for so long, or it was given by the monk named Chen Tingxu, and this big beauty didn't have to work hard to take out so many immortal stones. It is said that the immortal stone is a thing in the heavenly realm, and there is no one in the cultivation realm, where did she get it.

It was impossible for Yuan Tian to ask the palace master where the immortal stone came from, but when he filled the frame of the immortal stone. I saw a burst of bright light, and then all those immortal stones were gone.

"Where did you get the fairy stones, don't try to swallow them privately!"

Miss Su Su was very distressed when she saw that so many immortal stones were gone, although the palace master took out so many immortal stones, it was actually not easy to come by. She has such a good relationship with the palace master, and she has never seen the palace master so generous.

That is to say, the monks of the scattered immortal level have some immortal stones at their disposal, and how can ordinary great monks in the ascension period have such a thing as immortal stones, let alone use them to dominate. Now that so many immortal stones are gone, how can Miss Susu not feel distressed.

"Susu, you blame him wrongly. ”

The palace master is still much calmer than Miss Susu, and she is also very distressed when so many immortal stones are gone, but she is not emotionally out of control. And she noticed that after those immortal stones were gone, there was a trace of spiritual power fluctuations on the copper gate.

That's it, Yuan Tian was not bothered by Miss Susu's questioning. He stared at the place where the fairy stone had disappeared, and sure enough, he saw a complex pattern from there. As the saying goes, everything is inseparable, Yuan Tian observed the diagram in the frame position, which is actually similar to those difficult to crack in the Secret Realm of Trial and the Realm of Inaction.

It seems that it will take a lot of time to do it, and Yuan Tian analyzes it while looking at those complex diagrams. At this time, Miss Susu also noticed those complicated diagrams and knew that she was wrong. However, that Yuan Tian didn't seem to be planning to deal with her, but was seriously thinking about something.

What kind of picture is this, why is it black and white, and there are some things similar to tadpoles and small fish, the palace master's eyesight is good, and he can see the picture very clearly. But it's useless to just see clearly, she can't understand it at all.

I still know a little bit about this picture source, which should be a kind of connection between yin and yang gossip and Luohe map. When the Immortal Flute junior brother cracked the Lotu mechanism, Yuan Tian was also learning a lot by the side. Later, in the alley of the Abandoned Earth City in the Realm of Inaction, the last wall was the river map corresponding to Luo Tu, and Yuan Tian personally cracked it, of course, with some Fang Yin's help, anyway, he had memorized the cracking method.

This should be the node of the wood, so it should be broken with a metallic spell. The metallic spell Source Heaven will be a particularly low-level golden silk duel, that is, practiced by the monks before the fifth layer of qi training, and it is not very useful for attacking, mainly used for Lingtian insect control.

However, this time the Golden Silk Duel came in handy again, because this spell was very detailed and controllable. Cracking this complex formation requires not strength, but sufficient precision. After the first wooden node was broken by the Golden Silk Duel, it disappeared without a trace.

In other words, there is a small point missing from the whole complex diagram at the moment. Don't look at it, it's just a small point missing, but the palace master immediately saw the difference from it. I think how many times she and Su Su have been here, and they have slashed at the copper door tens of thousands of times without finding anything unusual.

This foreign monk was really not simple, and he poked his finger to find out the difference. After putting the fairy stone on it, I found this complicated diagram. After looking at this picture, the palace master understands that the key to opening the copper gate must be on this map.
