Hai Siyu swam along the surrounding rock walls towards the depths of the lake, around the rocks, there is nothing peculiar, it is still the same as the exposed lake rocks, but the only difference is that there are not so many algae at the bottom of the lake, and the algae are becoming more and more sparse, and there is not even a trace of life around, so to speak, the lake here is really a dead lake. Pen, fun, pavilion www. biquge。 info

The deeper he went down, the more he found that there were no large piles of rocks around him, and there was only one place in the entire lake that had such a large pile of rocks, and these rocks stretched all the way to the bottom of the lake.

Soon, Hai Siyu almost sneaked for about a few hundred meters, and then he vaguely saw the situation at the bottom of the lake, and the scene in front of him at this time made Hai Siyu really stunned.

At the bottom of the rock, there were six huge chains that connected the huge pile of rocks to the surrounding mountains, and the huge chains were already covered with thick moss, and each chain was connected to a rock, so that it formed a hexagonal rectangle, exactly the same as the arrangement of the rocks.

Hai Siyu stayed next to a rock, touched the iron chain with his hand, there was a deep cold on the chain, the cold almost made Hai Siyu shiver, this cold was too powerful.

The iron chain tightly held the rock and the surrounding rock wall together, almost in a straight line, and its length was more than several thousand meters.

"Damn, what's going on?" Hai Siyu couldn't help but stick out his tongue, who had nothing to do, and actually connected the rocks in the center of the lake with a long iron chain with a long iron chain, why did he do this?

Hai Siyu carefully walked around the surrounding rocks and circles, still found nothing, and saw everything in front of him as on the surface of the lake, the six rocks around him were still so tight, wrapping a rock in the center tightly, the only difference was that there were six more long iron chains, and I don't know if these six iron chains had penetrated into a rock inside, and in the four mountains around them, the iron chains went deep into how many meters.

Moreover, these seven rocks actually stretched straight to the bottom of the lake, how could the rocks grow so high, as if a small mountain was artificially cut into six straight and straight rock blocks, if it was naturally formed, it would be too much of a coincidence.

Hai Siyu suddenly emitted a purple fighting aura in his hand, and immediately grabbed one of the chains, shaking vigorously, hoping to find out how tightly this chain connected the two sides.

"Bang. A countershock violently knocked Hai Siyu over several meters, making a large arc in the water, and then stabilized his body, looking at the motionless iron chain with a disbelieving face.

"It's tight, it's tight, and there's a backlash. Hai Siyu said to himself.

Hai Siyu didn't care about the chains anymore, and stepped on the bottom of the lake, and with extreme care, he quickly scraped the moss off one of the rocks, revealing the rock surface inside.

Hai Siyu scraped all the moss on the rocks around him one after another, and finally saw the true face of the rocks, there was almost nothing on the six rocks, and it was just a very ordinary rock, and the only thing that made people feel strange was that it was such an ordinary six rocks, which would be tightly connected by iron chains that were thousands of meters long, you must know that it was such an iron chain that was thousands of meters long, and there was not even a trace of breakage.

Ordinary blacksmiths are to create chains that are tens of meters long, and it is impossible to have the ability to create such a long chain, which is quite difficult, and no one will do that at all, unless you specially customize a chain of such a length, but at a glance, you will know that such a long chain is not as simple as imagined.

Hai Siyu took out a long sword from the ring, this long sword was still stolen in the secret room of the Tianlong family, and it was a low-grade immortal weapon. As soon as the long sword came out, Hai Siyu slashed the long sword into one of the chains.

"Collapse. A subtle voice came out, and the long sword was shattered, and the chain remained intact, without even a trace, but the long sword was completely scrapped.

My God, Hai Siyu couldn't help but look at the long sword in his hand with wide eyes, this is a low-grade immortal weapon, not to mention how to sharpen iron like mud, but if you want to cut an iron chain, it is more than enough, but now it seems that these iron chains are not ordinary iron chains, since this one is not good, then change another one.

"Whew. This time, I changed to a big long axe, and the long axe slammed into the iron chain with a heavy fighting force.

"Hum. The lake was immediately stirred up and tumbled by the sudden attack of the long axe, but after only a moment, the lake regained its calm, and was replaced by Hai Siyu's bitter melon face, this time with the same result, the big axe was also shattered.

In this way, the two immortal weapons were scrapped here, and Hai Siyu only knew at this time that the immortal weapons could not break these chains at all.

Although the immortal weapon was scrapped, it made Hai Siyu also implicated, and the cold air made Hai Siyu's pores immediately close tightly, and his heart contracted violently, and he almost fainted from the cold.

However, after two tentative attacks, he had already noticed a trace of abnormality, and when he bombarded those chains, the chains were immediately wrapped with a small light element, and the powerful attack brought by the weapon was immediately forcibly blocked by the powerful shield formed by the light element, and then a powerful counterattack was also issued.

The attack from the immortal weapon held by Hai Siyu had reached the power of the ninth level, and the powerful defense formed by the light element was actually a whole two levels higher than the power of the eleventh level, but this power was concentrated to one point, so that the immortal weapon could be shattered in an instant.

It can be seen that these chains are not too hard, and the only thing that protects them is the light element that suddenly appears.

Previously, Hai Siyu had already noticed that within a hundred meters, the light element was extremely rich, and the eight series of magic elements were extremely thin, and at a hundred meters away, the light element was balanced with the eight magic elements, so if they attacked outside, would these chains still be protected by the light element?

Hai Siyu thought about it, and immediately swam a hundred meters away, and suddenly took out a long knife.

"Hehe, it's up to you this time, I don't believe in evil, if these chains are cut off, then what should happen? Hai Siyu said that it was too late, and he suddenly opened his fighting spirit, and the lake around his body was immediately forced to a few meters away by his own fighting qi fluctuations, and the long knife in his hand broke through the water flow again, and suddenly bombarded one of the iron chains.

"Hum. The chain made a buzzing sound, and it was instantly tightly wrapped by the sudden appearance of the light element, and an extremely strong anti-shock attack immediately rushed towards Hai Siyu, and the flowing water with that powerful attack power was like a sharp long sword, cutting through the surroundings, and it was about to hit the long big knife.

Hai Siyu quickly turned around, and the big knife immediately drew an arc in the water, throwing it towards the left rear.

That strong attack didn't collide head-on with the big knife, and directly hit the bottom of the mountain in the distance, and immediately smashed a big hole at the bottom of the mountain, Hai Siyu was not injured by the strong air current, otherwise he would have scrapped a fairy weapon again. Although immortal weapons are easy to come by, they can't be squandered so much.

But I never thought that just a few chains that looked like ordinary were so strong, and the immortal weapon had almost become an ordinary weapon, and you must know that the immortal weapon was a very powerful weapon outside.

Hai Siyu finally decided to give up attacking these chains, and instead came to the area around the six rocks, if there were any weirdness and mechanism, it would be these six rocks.

Hai Siyu stopped a meter away from the periphery of the rock, carefully infiltrating his spiritual power into the rock, still the same as before, firmly blocked by an extremely strong spiritual defense barrier, unable to move forward at all.

"Hmm. Looks like we have to start here. Hai Siyu once again increased his spiritual power, and his spiritual power formed an invisible dagger, which suddenly plunged into one of the rocks.

"Ahh Hai Siyu couldn't help but let out a scream, the dagger formed by the spiritual power was completely blocked by the rock, and this time he actually launched an attack, shattering the spiritual power emitted by the force.

The fighting qi shield around Hai Siyu disappeared immediately, and the surrounding lake immediately wrapped Hai Siyu tightly, and a trace of water immediately rushed down Hai Siyu's ears and nostrils.

"Whew. Hai Siyu suddenly forcibly turned on his spiritual power, and his fighting spirit was released for a while, and the disappearing shield immediately appeared again, and immediately forced the lake to a meter away, if he hadn't forcibly mobilized it, he would have been choked to death.

The bottom of the lake here is a full hundred meters away from the surface of the lake, although it is not very deep, but the pressure is still a little bit, so once there is no shield protection, the lake water will be driven by strong pressure to completely submerge Hai Siyu's facial features.

Hai Siyu soon sat at the bottom of the lake with a wheezing sound, panting vigorously, and soon returned to the original state. This time, a burst of mental power was released, and it immediately spread to the surroundings, since there is a barrier on the rock, let's take a good look around, hoping to find a clue.

Hai Siyu stood up and immediately followed the surroundings, and a complete image immediately appeared in his mind.

The huge hexagonal rock was tightly swayed by the six long iron chains, and each iron chain was closely connected to the surrounding mountains, and in the surrounding lake, the magic element between heaven and earth was slowly infiltrating the lake at this time, and finally stayed at a position of 100 meters around the rock, and was quickly absorbed by the surrounding lake water, and only the light element was forming a small point of light in an orderly manner and merging into the rock.

This process is extremely subtle, almost difficult to detect, if it were not for his strong mental power and keen magical perception, he would not have been able to detect the subtle flow of magical elements at all.
