"No, no, no, this is not a place I've been!" In the pitch-black water, Qi Yu, who was "stepping" on a huge thing of light under his feet, was "swimming" rapidly, and at this time, Qi Yu's eyes flashed with golden light, and he was constantly looking towards the dark area in the sea.

Below Qi Yu, that is, above the "ground" of the seabed, there is a huge ruin of the city, but because there is no light around, it looks a little strange.

However, this is naturally nothing to Qi Yu, with the blessing of mana and divine thoughts, Qi Yu naturally swept away this huge ruin, constantly observing its appearance.

Although this city in the depths of the sea is already in tatters, it is not without things that can be "observed", whether it is the architectural style, style and vague decoration in the city ruins, it is very similar to the ancient sea tribe city that Qi Yu and the three fish people explored on the bottom of the sea before, so Qi Yu will have what he said before.

However, the ruins of the city that Qi Yu "found" at this time seem to be larger, and there are no strange protections of the so-called heavy water protection relics in it, but they are completely exposed to the water, but no matter how you look at it, there should have been a defense system here before, otherwise the city would not have such a regular space.

According to the previous situation above the sea, I think the defense here should have been destroyed by the energy falling from the lightning tribulation many years ago, leaving this area exposed.

As a result, although the buildings here retain the appearance of urban agglomerations, most of them have been destroyed, and the degree of destruction is not low, basically a large area of "foundation ruins".

But this does not mean that there is nothing in this ruin that can make Qi Yu pay great attention, that is, the "building materials" that have survived the thunderstorms over the years.

Some of the building materials here are obviously specially made, so they have been in the sea for so many years, and they have stood under the erosion of thunderstorms, but even the most precious materials are spiritually lost and cannot be used.

Qi Yu's concern about the "building materials", but under this endless thunderstorm to absorb the power of thunder and lightning and keep the material, although I don't know what it is called, but it makes Qi Yu extremely surprised, especially after Qi Yu found a gray pillar flashing with golden thunder, Qi Yu does not plan to leave, because with the thunder and lightning induction of his thunder method, this strange "thunder and lightning stone" will definitely be of great use in the future, and it is impossible to say what magic weapon of thunder and lightning attributes can be refined.

Due to the improvement of mana, Qi Yu's movement speed in the water was extremely fast, and he soon browsed a large area, but the things he wanted did not let Qi Yu find them a few times in the building complex, because there are not many thunderbolt stones, and sometimes there are only so many small ones, which makes Qi Yu smile bitterly when he picks it up.

But in line with the principle of not missing and not letting go, Qi Yu still put away these small thunderbolt stones.

In the whole process of Qi Yu's movement, it can be found that Qi Yu did not turn into a water body, but due to the thundering secret technique, the traceless water integrated into Qi Yu's body has "disappeared", so Qi Yu's traceless water body can no longer be used.

When he first entered the water, Qi Yu was still a little disappointed, but these were just small prices to pay, nothing more, and the use of traceless water bodies was not suitable for most situations, and special treatment was required.

I don't know what the thunder and lightning stone of these stones is, they are scattered very little, and they are extremely "hidden", and the scanning of the divine mind is not enough to distinguish these stones, and only when they automatically show some thunder light can they sense their specific existence.

So many times, Qi Yu flew out of a long distance, and suddenly felt that there was some "thunder light" in the area he had just flown over, and he had to turn back and look for it carefully.

Such a situation naturally makes Qi Yu dare not have any slackness to cover the divine thought to the maximum, so as not to miss this strange material, but the loss of the divine thought is naturally very large.

In the process of flying, Qi Yu had already taken out some of the "small" wreckage of the previous hull at will, but it was those thunder woods, and after comparing these woods with the stone, Qi Yu was even more surprised, because the power of thunder and lightning in this stone was actually more than these wood, which was really a treasure of heaven and earth.

Qi Yu didn't dare to slack off, and his figure continued to search at the bottom of the sea.

"How can this be!" Qi Yu, who was flying, first lit up with thunder in his hand, and then said so, and as the thunder light in his hand dissipated, a round stone that had previously emitted thunder light cracked after a "click".

Without waiting for Qi Yu to do anything, the thunder light on the round stone flourished again, and the next moment when the thunder light dissipated, the round stone in Qi Yu's hand was already "gone", but it was directly turned into powder after being consumed and integrated into the seawater.

However, at this time, some flashing lights appeared around him, and Qi Yu only glanced at it and then looked into his palm.

"This heaven and earth treasure is a one-off?" Qi Yu naturally realized what in this situation, these stones have existed in the water for so many years, and after absorbing a huge amount of thunder and lightning power, they actually become extremely fragile, if you can't use some special methods to deal with it, I'm afraid it can't be of any great use, this is really a second to be slapped in the face, it's really a little uncomfortable.

However, Rao is like this, Qi Yu's body still has mana, and he is heading towards the place of light that flashed around him before, after all, this kind of thing is still hard to find.

...........

"There must be some problems here, what do you say, Pixiu?" After a big turn, Qi Yu once again returned to the place where he first flew into the water, looked at the seemingly irregular architectural ruins in front of him, and asked Pixiu.

However, at this time, Pixiu did not have any other reaction except for giving an affirmative message, and even Qi Yu did not feel any emotional fluctuations in Pixiu, and he didn't know what the situation was with these thunderbolt stones he got.

Pixiu already likes natural treasures, so it is not the same as his "vision", in Qi Yu's opinion, the availability of these stones is still very high, after all, after a long time of on-demand, the angle of many things is different in Qi Yu's view.

The reason why Qi Yu returned to this place at this time was because Qi Yu explored a large area, but unexpectedly found that the further he went to the outer circle from this location, the less "thunder and lightning stone" Qi Yu could collect, and the smaller that stone became, not to mention the higher and higher the probability of "breaking".

That is to say, there must be something special here that makes the materials here so well preserved, but I didn't see anything near the middle.

Thinking like this, Qi Yu's eyes narrowed slightly, and he had already taken out a gray stone in his hand, and the power of thunder and lightning flashed in his hand, and several thunderbolts poured into the stone.

The next moment, the stone was already thunderous, like a lit thing that directly illuminated the surroundings, but this also caused the stone in Qi Yu's hand to quickly "disappear", and it dissipated in the water in a few breaths, but a large piece of bright light still lit up around Qi Yu, and Qi Yu's eyes lit up.

Rotate a few times in place, the position of the surrounding bright light, the size of the Qi Yu is sitting cross-legged in the sea, after the eyes are closed, a bright circular figure is in front of Qi Yu, and then some two points appear in this circular pattern, at a glance, you can see that Qi Yu is simulating the light points that he saw before, and from time to time there are some lines between these light points, but soon the pattern is gone, and Qi Yu is restored to its original state.

"No wonder there is this kind of material, it turns out that a giant spirit gathering array is arranged here!" After Qi Yu muttered a word, with a wave of his hand, a large number of blue thunderbolts flew out from Qi Yu's body, quickly shuttling out on the dim undersea ground, but it was to "lift up" and "light up" some of the surrounding building wreckage!

"It's still not enough!" Qi Yu has just learned the control of the power of thunder and lightning, so he doesn't have too strong control ability, although there is a lot of blue light around Qi Yu at this time, but there are still some differences from those that appeared before.

There was no way, Qi Yu waved his hand again, and a large piece of golden light flew out, flying farther away at a very fast speed, and soon disappeared into the surrounding ruins and disappeared, and the surrounding buildings began to hear the sound of building materials moving or something else, and the bottom of the sea was lively for a while.

If it weren't for the fact that it was at the bottom of the sea, if it weren't for the fact that there was indeed a person around and no living beings, this kind of excitement might still be more comfortable, but unfortunately Qi Yu just felt a little "chill down his spine" at this time!

Feeling this situation, Qi Yu could only pout his lips, exhaled lightly and raised his left hand in front of his chest, and there was an extra hexagonal magic disk on his palm, and with a pinch of his right hand, a large amount of light on the hexagonal magic disk in Qi Yu's hand "rushed to the sea" and quickly fell around, and this time, the sound of the surrounding buildings moving became stronger.

At this time, what Qi Yu had to do was to activate the Spirit Gathering Array in this area, because although Qi Yu had "accumulated a lot" and rapidly improved his cultivation before, there was always a sense of unfinished business, and Qi Yu felt that he still had some potential in his body, which had not been fully stimulated.

But who knew that "it didn't take any effort to get it"! Actually let himself encounter such a good spirit gathering array, Qi Yu naturally wanted to "cherish it", and when the time came, he would definitely be able to make his cultivation speed reach the fastest, and maybe he could try it when he got married.
