The modularity of the formation pattern, this is simply a genius idea, why didn't you think of it before?

This is like a primitive handicraft workshop, which has been instantly upgraded to a Foxconn assembly line operation, and the improvement in efficiency is not a star.

Su Can had even forgotten that he was still trapped in this underground cave at the moment, and the whole person was silent in the study of this formation.

Qu Feiyan on the side naturally couldn't see this formation, and he couldn't see the Eternal Night Heavenly Monarch hiding in Su Can's body, let alone hear the conversation between the two, he only saw Su Can looking at him with interest, for the cultivation of the two of them, there would be no problem holding their breath in the water for a long time. Although he didn't understand what Su Can had discovered, he still followed him quietly and never left.

Time passed minute by minute, about a stick of incense passed, Su Can took Qu Feiyan to grope along the edge of the invisible formation in the dark river, the two had already arrived at the cliff position, although the formation pattern had been studied by Su Can, but there was still no way to crack it.

Although this formation made Su Can have an unexpected gain, he was still trapped in the cave, which still made him a little depressed.

It stands to reason that he and Qu Feiyan were washed into this cave from this underground dark river, and they can at least return the same way, how could they be so obstructed by such a formation?

Su Can frowned, and suddenly saw the fish in the water, which seemed to be free, but he noticed a strange phenomenon.

That is, the fish under the formation can swim out of the formation freely, but the fish above the formation will be hindered if they want to sink into the depths of the dark river.

Su Can's heart was sudden, no wonder...... There are so many fish in this dark river, and there are even the bones of fish and beasts on the riverbank, it seems that this formation pattern can enter but not exit!

This discovery made Su Can's heart heavy, and in the end, he could only prepare to return to the riverbank to think about it in the long run, if he couldn't find a way to make a hole, he didn't believe that he couldn't get out.

Su Can was ruthless, but just as he was about to leave, his palm inadvertently brushed over the cold and dark cliff, and in a trance, something seemed to have been touched, and a streamer suddenly appeared on the cliff, and at that moment, Su Can clearly felt that the formation that blocked them was also touched, and it suddenly lit up.

Although the faint light flashed away, it was still keenly captured by Su Can.

Originally about to leave, his body stagnated slightly in the water, and then his eyes fell on the cold cliff wall that he had brushed casually before.

The cliff was dark and cold because it was deep underwater, but at this moment, Su Can was surprised to find that the cliff was as smooth as a knife cut, and that flatness was definitely not formed by the natural erosion of flowing water.

It seems to be a man-made trace.

Su Can's heart moved, and he stretched out his hand to carefully brush the cliff wall, erasing the slippery algae formed by the erosion of time, and a touch of metallic luster appeared in front of him.

To Su Can's surprise, I don't know what kind of metal it was in front of him, soaked in the water of this underground dark river for I don't know how many years, it was still as smooth as a mirror, and there was no trace of rust on it.

Su Can carefully wiped the algae on it and found that it was a metal block in the shape of a stone tablet inlaid into the cliff wall.

Su Can took a closer look and was pleasantly surprised to find that this piece of metal was the eye of this huge magic circle.

If you find the eye of the formation, you will have the possibility of unlocking this formation and leaving this underground cave.

Su Can couldn't stop his ecstasy, but then he had some difficulties, how could he unlock this formation?

Is it possible to break it violently?

This is the most straightforward way to do it.

Although this metal looks extraordinary, it ...... If it's smashed, you can still take it with you.

So Su Can didn't feel the slightest distress, but what made him depressed was that no matter how hard he used, the metal block didn't move at all, not even a trace of crack appeared, and even the true yuan mana he injected into his body was like a quagmire.

Su Can's old face was a little blue, and Qu Feiyan on the side couldn't help but take a hand when he saw this scene.

But even if she was a human king realm, she was a whole realm higher than Su Can, and the True Yuan that also gathered her whole body bombarded the surface of the metal block, and it was still like a quagmire, and there was no response.

Seeing this scene, both of them frowned, and in the end, the two of them who did not give up bombarded the metal block embedded in the cliff wall with all their strength at the same time.

This time, the metal block finally reacted somewhat.

However, it did not explode as imagined, and the formation was not cracked, but the smooth mirror-like surface was filled with extremely complex light, converging into a circuit like the most complex circuit board, and then ...... Su Can keenly sensed that something had recovered.

Su Can and Qu Feiyan glanced at each other, their faces changed, and they suddenly had a feeling that they were in trouble.

He was about to slip away first, but at this moment, a cold and mechanical voice came from the metal block: "The Inheritance Trial Begins!"

The deep voice echoed in the water, making the footsteps of the two who were about to slip away stagnant again.

Legacy Trials?

Su Can and Qu Feiyan didn't understand a little, but at this moment, the dark river around them suddenly surged, and then the light of the formation that blocked them bloomed, and at the same moment, on the metal block that was originally embedded in the cliff wall, the more dazzling light spread out like a circuit board, and even centered on the metal block, turning into thousands of tentacles, densely and instantly covering the entire huge cave.

Su Can and Qu Feiyan were slapped on the river bank by the waves, and they only smashed seven meat and eight vegetables, but the two of them didn't have time to snort, but they were dumbfounded.

At this moment, in the cave where they were, the dense light was regularly covered with every inch of the cliff face, and under the reflection of this fluorescent light, in the dark river in front of the two, a fish that was originally the most ordinary shot out, and was still hit by a ray of light shot out of the metal block in mid-air.

In the incomparably stunned of Su Can and Qu Feiyan, they actually directly transformed into a giant insect with a hideous body and trembling tentacles, and smashed down on the riverbank......

For a while, the gravel was splashed, and the momentum was terrifying.

What the hell is this?

Su Can was dumbfounded on the spot, his shocked eyes almost didn't protrude, and Qu Feiyan on the side was no better, and his pretty face was shocked inexplicably.

When the two of them were shocked, two rays of light shot out from the water, but this time they were aimed at Su Can and Qu Feiyan.

Seeing this situation, the two people who were only frightened were trembling, afraid of being hit by the light, and suddenly turned into that extremely ugly giant insect creature.

The two tried to dodge, but as soon as the thought moved, they were struck by the light.

However, the two of them did not turn into giant insects like the fish before, they only felt a trace of warm air flow sinking into their bodies, and other than that, there seemed to be nothing abnormal.

It's just that the next moment, when Su Can and Qu Feiyan's eyes fell on the giant insect, their expressions became exciting.

Because at some point, a ...... actually popped up on the head of the giant worm Health bar!

What the hell is this?
