In the area where Xitie was discovered, Wang Lun arranged fifteen enlarged circles before and after, and nothing was found, but he continued to take the area as the center and expand the area of the array around.

After all, if the most magical place in the entire spiritual mine is undoubtedly the place where the iron appears, this area is the most special.

Therefore, Wang Lun's plan is also very simple and clear, that is, to start the formation from this area first, and if there is no gain, it will spread around.

Another hour had passed, and Wang Lun had already been more than three thousand meters away from the Xitie area, because the underground mine was curved and irregular, and he couldn't see the Xitie area when he turned around at this moment, so naturally, Wang Lun was even more unlikely to find the two shadow stones.

After two hours, not tired at all, Wang Lun continued to move forward, and came to the area that had been subdivided before. This area is numbered 22.

This means that he has been deployed 21 times before.

It can be deployed about 10 times in an hour, and it will only dawn in five hours at most, so it can be customized to be able to deploy 50 times, and now it is almost half of the work.

Because he had explored in the "Lingyue Day" so many times before, and had not gained anything every time, Wang Lun would no longer be discouraged when he saw that the magnification circle had not achieved results.

Disappointment or something, when doing this, there is no such thing.

Wang Lun continued to arrange the magnified magic circle.

Soon, Wang Lunbu's array came to the 29th time.

It was the deepest of the 29 areas he had explored. The area has been dug up a deep distance because of the deep burial of the iron, but it is still shallower than the current area.

He also knows why.

This area is a geological loose area, and it didn't take long for the miners to collapse after they dug up the spirit stones. The cause of the collapse was not due to groundwater infiltration, as there were excellent groundwater drainage facilities throughout the mine, because there was less rock and more soil in the area.

After the collapse, it sank and formed a large crater with a deep bottom.

Wang Lun is at the bottom of the pit at the moment.

The area of this pit is huge, and it is divided into three areas by Wang Lun: 29, 30, and 31, which means that three magnified magic circles must be arranged in the pit before the exploration can be completed.

For the 29th time, Wang Lun was still in a stable state of mind, and inserted the newly replaced array flags one by one in the shallow soil at the bottom of the pit, so that all the array flags could stand firmly.

Then Wang Lun released his mana, and all the array flags emitted a layer of bright light, which was lit up, actually forming an energy field.

In this energy field where all the array flags work together, the frequency is the same, that is, it constitutes a whole, echoing the sun and moon essence energy in the "Spirit Moon Day" at this moment.

On the day of the "Spirit Moon Day", the essence of the sun and the moon is the most active, correspondingly, the high-level energy in the secret land will also be extraordinarily active, and the amplification circle that is now arranged has formed an energy field, if somewhere below is a secret place containing high-level energy, then as long as a certain frequency of the energy field, at a certain moment, and the frequency of the high-level energy in the secret land have reached the same level, a resonance will be formed.

At that moment, the change of the formation flag caused by the resonance could be observed with the naked eye.

The subtlety of this approach is that

The first is to choose the day of "Lingyue Day", where high-level energy is the most active and has the greatest possibility of being discovered, and the second is to use the amplification circle to amplify the effect.

If you casually plant a flag on the ground, even if there is high-level energy underneath, the flag will not change in any way. After all, the high-level energy would not show any abnormalities before it erupted, and even if the high-level energy was more active on the day of the "Spirit Moon Day", it was impossible for the monk to perceive it.

If you could sense it casually, those powerhouses of the Transformation God Realm would have already searched for high-level energy in the spirit realm.

The eldest grandson's family can study the magnification array, which Wang Lun admires very much, even if Wang Lun himself, even if he mastered the physical phenomenon of resonance in his early years, he can't use it and arrange the magnification array.

At this moment, the energy field has been formed, and it has begun to absorb the energy of the sun and moon essence. When he found that there were light spots between the array flags connecting all the array flags, Wang Lun knew that the magnification circle was officially arranged.

What the amplification circle borrowed was not Wang Lun's own mana, but the absorbed energy of the sun and moon essence. Now that it's set up, it's just a matter of oscillation.

Wang Lun manipulated the amplification array, gradually oscillating from low frequency to high frequency, looking for the existence of high-level energy in the surrounding underground.

This whole set of actions, Wang Lun has done so many times, and he can't be more familiar, but this time, when the oscillation frequency of the amplified magic circle reached a relatively high level, Wang Lun's calm heart suddenly jumped suddenly.

Because the array flags that had been looking at them with their heads down, they all trembled at this moment!

Wang Lun is sure that this change has really happened, not his own dazzle!

Wang Lun didn't dare to come out at the moment, he was excited, but he was more nervous, for fear that he would miss it, and his eyes continued to stare at the formation flag.

All the array flags trembled for about two seconds before they stabilized again.

With the naked eye, even if the tremor is not large, it is clear that this tremor really happened!

Although the tremor phenomenon has disappeared now, it is entirely possible that the high-level energy is in operation, after all, the high-level energy in this state, first, the frequency itself is different, and the second is that it changes every moment, and the resonance frequency received by the array flag is only a specific frequency emitted by a certain piece of high-level energy.

Therefore, Wang Lun quickly activated the vase mark on his chest and began to summon the Ten Thousand Spirits Treasure Vase to come out.

Because Wang Lun was afraid that the high-level energy was moving. This is what the eldest grandson Wuxiao specifically mentioned to him, the secret place containing high-level energy is not fixed forever, the high-level energy will move around in the depths of the ground, and the secret place will naturally change.

Of course, even if high-level energy moves around, it is basically very slow, but it cannot be ruled out that high-level energy in some cases will move very quickly.

Like the secret place that the eldest grandson family mastered last time, from being discovered, to Wang Lun knowing, and then to Wang Lun's introduction of the sloppy Taoist into the secret place, several days have passed before and after, and the movement distance of the secret place is also very small.

As soon as the treasure bottle came out, Wang Lun immediately held the treasure bottle in his hand, and immediately cast the earth escape spell himself, forcibly breaking through the surface soil and the rock layer below, and moving deep underground.

Because the Wanling Treasure Vase will only be actively absorbed after it is in front of the high-level energy, and the high-level energy is activated. Other words

High-level energy has to be exposed.

So at this moment, there is no change in the Wanling Treasure Vase in his hand.

Wang Lun moved vertically downward, because the magnified circle reacted, showing that there was high-level energy directly below the circle. As for the specific depth, Wang Lun doesn't need to know.

Because Wang Lun moved down vertically, using mana to detonate it. The mana at this moment is like a flame coming out of a lighter, in order to directly detonate the high-level energy after coming into contact with the high-level energy.

Wang Lun had no other suitable way. He couldn't perceive it with his divine sense, and the high-level energy would not show any abnormalities until it exploded by itself, so under ordinary circumstances, he couldn't judge whether he had reached the area where the high-level energy existed.

Of course, if there is enough time, it can be done in the same way that the eldest grandson family determines the specific location and specific size of the secret land, that is, continue to arrange the magnified magic circle underground, and again and again, through the size of the tremor frequency of the array flag, determine where is the real area where the high-level energy exists, and the range of the high-level energy.

That way, not to mention that there are only two hours before dawn, even twenty hours may not be enough.

It was precisely because Wang Lun took this into account that if the location of the secret place was determined in such a safe way by the eldest grandson family, there would be two surprises.

The first is naturally the fear that the location of the secret place will move. If he is on the move, he is using the magnification circle to try to determine the position, and the secret place is moving, and if he doesn't do it, he will be busy in vain.

Of course, this is not the most important reason. After all, the chance of moving in the secret land is not very large, and even if it does, the speed is almost not very fast.

What really made him give up this method was that after dawn, the boy would find that he was gone, and he would take the initiative to look for him, and he would probably be forced to interrupt the investigation, and he would not be able to get the high-level energy in time, or he would be discovered by the boy.

He is now in the Spirit Sect, and the Spirit Mine is in the Spirit Sect, and he is constrained here and there, so he can't spend the time and time to do this slowly, so he can only give up this practice.

High-level energy is indeed precious, this is also a time that he finally discovered, but the reality is so cruel, it is impossible that good luck has always been his, he has thought about it, this kind of safe method will not work, almost 100% will go wrong.

Now directly use mana to try to detonate high-level energy, the method is the simplest and rudest.

At the moment of the explosion of high-level energy, the Wanling Treasure Vase will actively absorb high-level energy.

Moreover, it is not like the last time it dealt with sloppy Taoists, it was the kind of large-scale explosion.

This time, he will only use his mana to detonate a portion of the high-grade energy, even "a horn". It's easy to do this, his mana attack is not scattered everywhere, but is controlled by him in a small range in front of him, and his mana attack is not violent, not powerful, and the effect is to act as a small flame that detonates explosives, not a large fire.

Therefore, if this small bit of mana does detonate high-level energy, on the one hand, the speed of continuous explosion will be relatively slower than the detonation of a large amount of mana, so that the Wanling Treasure Vase will have more time to absorb energy, and on the other hand, he can also make a move in an instant, setting up an enchantment to forcibly isolate the explosion area.

It's not like what happened last time in the Secret Lands.
