However, what seemed to be a feasible method in theory was difficult for Lin Feng to implement. Because even a highly skilled formation master would be able to calculate the position of the formation eye composed of sixty-four array stones in a short period of time, not to mention that Lin Feng's comprehension of the formation path was still very superficial, and it was definitely not possible to achieve this level in a short period of time.

But if he couldn't find the formation eye, Lin Feng would be trapped and die in this ancient demon hall, and the ** of survival can often stimulate the potential of instinct, and most of the effects are extremely powerful.

After an hour of immobility, Lin Feng didn't even blink his eyes, the sixty-four array stones finally solidified into a pattern in his mind, and Lin Feng could even be sure that this sarcophagus was completely specially created to cooperate with this confinement array, because the position of each array stone on the sarcophagus was set to conform to the effect of the confinement array.

Lin Feng's eyes were fixed on the sixty-four array stones, but in his mind, he was constantly calculating the relevant connections between any array stones, and the only point that could be referred to was the array heart on the coffin lid, which was used as the junction point between the magic array and the sarcophagus, and it could be inextricably linked with the spiritual power of other array stones.

In the high-intensity operation of his mind, Lin Feng had already entered the realm of self-forgetfulness, but unfortunately, with his formation attainments at this time, he could not complete such a huge amount of calculations in a short period of time, and if he had been allowing his consciousness to continue to calculate endlessly, then the final result would probably be to let his divine thoughts fall into a tragedy from which he could never recover!

However, as time passed, the situation in front of him still changed! The scene that Lin Feng saw no longer had the huge sarcophagus, but only the sixty-four array stones left! This is a phenomenon that only appears when consciousness is condensed to a certain extent, and it has reached the realm of removing the false and retaining the truth and the unity of things and people.

This seems to be a life-and-death gamble, Lin Feng has been deeply trapped in it and can't extricate himself, if he can't crack this array as soon as possible to get out of the mystery of forgetting himself, then the final result can only be death!

And an hour passed again, but Lin Feng still made no progress, but the worst thing was that his mind had reached the limit of exhaustion at this time, and when he was about to fall into a permanent sleep, the mysterious immortal net came forward again!

Following "Capture", "Devouring", "Quenching", and "Void Spirit", the fifth nameless magic technique appeared in the fairy net: derivation!

The initial appearance of each nameless magic trick happened when Lin Feng inadvertently or was on the verge of death, the magic formula itself did not have a name, but was just a consciousness forcibly instilled into Lin Feng by the immortal net, but according to this consciousness, Lin Feng instinctively felt that the mystery of this magic trick was "derivation"!

Once the "Derivation" method was put into operation, the Immortal Net seemed to bring Lin Feng into a vast void, and the void was full of countless dotted stars, each star and the surrounding stars would form a strange array association, and the combination of the vast stars was an endless array of Derivation!

Under the urging of the "derivation" method, the sixty-four array stones on the sarcophagus quickly found their corresponding star positions in the endless void, Lin Feng only needed to correspond the array heart at the top of the coffin lid to his own position, and the immortal net would automatically calculate the location of the formation eye of this imprisoned magic array, and the time was only a blink of an eye!

What Lin Feng did next was beyond the reach of any array master! I saw him stretch out his hand, and a white light suddenly shot out, completely ignoring the shield of the confinement array, and directly submerged into the sarcophagus!

If someone could see the situation inside the sarcophagus, they would definitely see the white light emitted by Lin Feng at this time, and it hit a formation stone with incomparable accuracy, that is, the formation eye of this imprisoned magic array! (・)

And the white light was a void spirit power emitted by Lin Feng, the void spirit power ignored the restrictions of spiritual power, and had a powerful destructive effect on spiritual power. This void spirit power did not shatter the array eye, but instead pushed it away from its original position for a certain distance, causing a new change in the confinement array!

Due to the displacement of the array eye, the sixty-four array stones also made corresponding changes, some of them were deeply embedded in the sarcophagus, some protruded from the sarcophagus, and some even extended directly into the air and floated.

Lin Feng once again used the "derivation" technique of the immortal net to accurately find the location of the array eye, and the second void spirit power came out, but unfortunately it was still unsuccessful, the void spirit power was not enough to shatter the heavy array eye, and the power contained in it was all offset by the array eye, but at the same time, it was also reducing the spiritual power contained in the array eye.

After more than a dozen white lights were gone, Lin Feng's face was already pale, but there were already spots and cracks on the array eyes, but he couldn't see it. At this time, in the Ancient Demon Palace, a large amount of demonic qi had already spread, and if he didn't leave this place quickly, Lin Feng would not be able to escape death after all.

The consumption of spiritual power by the "derivation" method of the immortal net is beyond imagination, and the frequent use of virtual spiritual power makes the immortal net even more overwhelmed, and the weakest formation eye in the magic circle still has such a powerful spiritual power defense, it is conceivable how amazing the spiritual power strength of the sixty-four array stones will be!

Lin Feng had no other way to go, he could only use the "Derivation" to determine the position of the formation eye again and again, and then attack it with one by one Void Spirit Power. For all the magic circles, the most labor-saving way to crack is to break its array.

And the most cumbersome way was to break the sixty-four array stones one by one, which was almost impossible for Lin Feng, because it was so difficult to even have an array eye, let alone the sixty-four stronger array stones.

Fortunately, after the twenty-first void spirit power was released, a crisp sound finally came from the sarcophagus, followed by a falling sound of ping-pong, and since the array was broken, the sixty-four array stones on the sarcophagus naturally fell to the ground.

Lin Feng let out a long breath, he didn't have time to take any rest, he hurriedly approached the sarcophagus, and used the giant force technique to open the heavy coffin lid, and after seeing the situation inside the coffin, he was stunned on the spot again!

In the huge sarcophagus, there is actually a space more than ten zhang wide, and the stone wall of the giant coffin alone has a thickness of more than five zhang, no wonder his divine sense cannot see through the internal situation. And in this sarcophagus, there is a huge skeleton without a head, and a strange ancient tree without a canopy!

The four walls of the entire giant coffin were densely filled with countless strange symbols and words, Lin Feng seemed familiar when he saw them, but he didn't have time to think about where he had seen similar words, because at this moment, he was the first to discover the origin of that ancient tree!

This ancient tree without a crown is one of the six sacred trees recorded in the Bailing Bamboo Slips: Requiem Wood!
