"Then you think I can see through it?"

Tang Yu looked a little unhappy, what he couldn't even see through with a pair of eyes could be seen through with his eyes?

"Don't worry..."

Yu Chengxuan patiently explained: "Spirit beast wrist storage ring, these things can't be seen through by the gods, but you can easily see through them, so I want you to try it." Don't worry, there is not much danger in that place, although the Tuoyue Phantom Spirit can charm the mind, but the body is very fragile, and it is like the peak of the body, if you can see through the fog, just do it in advance! Even if you can't see through it, I will put a positioning stone on you, and if you don't come out for more than three days, I will go in and forcibly pull you out!"

"Three days?"

"Yes, three days!" Yu Chengxuan nodded and explained: After so many years of capture, there are very few illusions, which is also a reason why I want you to help, after all, it is too difficult to try your luck!"

"That's it..."Tang Yu pondered for a moment and then asked, "Then is this thing the only thing there?"

"Yes!"

Yu Chengxuan nodded and looked at Tang Yu expectantly.

Now Tang Yu was embarrassed, originally he wanted to exchange a little in the system, but it was difficult to do it if there was only that place. He could also exchange it for some other things instead, but he took the time to take a look at the system store, the price of this elixir was too high, it was not cost-effective, and he would not agree to it when he told Yu Chengxuan, and it was even more impossible to post it himself!

After thinking about it, it seemed that there was only one way to agree, and looking at Yu Chengxuan's expectant eyes, he couldn't bear to refuse, let alone for Yu Rong.

Maybe it was because of guilt, Tang Yu nodded and agreed: "Okay, I agreed!"

"Good!"

Yu Chengxuan said happily: "Don't worry, my Yu family won't treat you badly!"

Tang Yu shook his head lightly: "That's not necessary, I'm for Yu Rong!"

Yu Chengxuan waved his hand indifferently: "No matter who it is, I owe you a favor!"

"Okay!"

Tang Yule was happy, although he didn't know Yu Chengxuan's specific cultivation, but judging from the fact that Yu Yangqiu was forced to do so and didn't dare to make a move, it was definitely not low in the middle of the Yuan Infant!

"Let's go!"

Tang Yu asked suspiciously, "Where are you going?"

"Tuoyue Island?" Yu Chengxuan said as a matter of course.

Tang Yu was helpless, and said with a wry smile: "I said senior, do you think my current state is appropriate?"

Yu Chengxuan turned his head to look at Tang Yu, who was pale, and reacted suddenly, smiling awkwardly: "Then tomorrow?"

"Okay!"

Tang Yu nodded.

"Then I'll have you sent back?"

"No need!" Tang Yu shook his head and refused: "Just let my two brothers take me back!"

"That's fine, I'll let them both in. ”

After Wang Chunyun and Yu Yongfan came in, they saw the weak Tang Yu and almost ran away, if Tang Yu hadn't stopped him, Wang Chunyun would have started directly, and it was resolved after Tang Yu's repeated explanations.

The next day, the transparent energy at the center of Tang Yu's eyebrows was restored, and after a night of research, he didn't find anything to do, only knowing that this energy could be used to strengthen his eyes and see places that others couldn't see. The energy recovery also appeared out of thin air, and no matter how much he probed, he could find out where it came from.

But fortunately, the energy recovery is relatively fast, and it can be fully recovered in about an hour. And as long as you don't use it all at once, you won't get dizzy and unsteady on your feet, but it will be a little uncomfortable.

What made Tang Yu most curious was that the place where the transparent energy was stored in the center of his eyebrows was actually highly consistent with the dantian, if he didn't look at the location, it was simply another dantian! And in this case, he had never heard of any monk appearing. But fortunately, this thing didn't have any effect on him, which made Tang Yu feel a little more at ease.

Out of the inn door, Yu Rong and Yu Fei were ready to go. After instructing Wang Chunyun and Yu Yongfan not to run around, Tang Yu followed Yu Chengxuan out of the city.

Seeing Tang Yu again, Yu Yurong looked very calm, just glanced at him lightly and then looked away. This made Tang Yu breathe a sigh of relief and a little lost at the same time. This emotion came inexplicably, but Tang Yu covered up the past very well.

The guards at the gate of the city obviously knew who Yu Chengxuan was, and the way they nodded and bowed was very different from when Tang Yu entered the city.

After leaving the city, Yu Chengxuan waved his hand, rolled up the three of them and galloped in one direction. That speed made Tang Yu envious.

The location of Gu Ya City was on the edge of the Thunder Sea, so it didn't take long for the four of them to rush to the Thunder Sea.

"This is Lei Hai?"

Tang Yu was deeply shocked by the scene in front of him, the black thunderclouds shrouded in front like a curtain, like a boundless black city wall surrounding the edge of the land, and people standing below looked extremely small. But the strange thing is that there is not a single thundercloud floating over the land, and when it reaches the seashore, it stops abruptly, as if it was controlled by someone, and it is extremely accurate.

"Yes, this is Lei Hai!"

Yu Chengxuan's reaction to Tang Yu was not strange, everyone who came to the Thunder Sea for the first time would be shocked by this natural power, and even he, a person who grew up on the Thunder Seaside, would feel a ripple in his heart every time he saw such a scene.

Yu Rong and Tang Yu's expressions were similar, their mouths were slightly open, and they couldn't close them for a long time.

Yu Fei looked much calmer, and his expression was not so exaggerated. It's just that from his slightly trembling legs, it can be seen that he is not so calm inside.

Tang Yu walked slowly to the Lei Sea, and as soon as he touched the seawater, a tingling sensation came from the soles of his feet, which frightened Tang Yu and hurriedly jumped away.

Yu Chengxuan explained with a smile: "The Thunder Sea is covered by thunderclouds all year round, and countless tired points are cleaved on this sea day and night, after an unknown number of years of accumulation, this sea water has already become a veritable Thunder Sea!"

"It's so strong!"

Tang Yu sighed, and couldn't help but put his hand into the sea. This time, Tang Yu was prepared, carefully felt the feeling of being electrified, and was surprised to find that even on the very edge, the intensity of this electricity had reached hundreds of volts!

"People who have never been to this place think that the most dangerous thing in the Thunder Sea is the lightning in the sky, but in fact it is not, the most dangerous thing is this seemingly calm Thunder Sea, in the deeper depths, even if the Yuan Infant Monk is not careful, it will be electrocuted into ashes! That's why it is said that the Thunder Sea cannot be crossed by the Divine Transformation!" Yu Chengxuan explained on the side.

Tang Yu listened carefully, and inevitably thought of the black-robed man who let him see Zhongzhou again, he had just heard Yu Chengxuan say that he was very strong, and he didn't have an intuitive concept, but now when he saw Lei Hai, he couldn't help but feel a trace of despair, could he really stop such a strong person?

Yu Chengxuan didn't know what he was thinking about now, and after a brief introduction, he took out a small boat, on which there was a faint flow of light, which looked extremely strange.

"Let's go, Totsuki Island is still in the depths of the Thunder Sea, we have to hurry!"

"Good!"

The three of them did not have any objections and followed on board.

Yu Chengxuan stood at the bow of the boat, his hand on a raised wooden platform on the bow of the boat, and continuously transmitted spiritual power towards it, and the small boat was like an arrow, galloping towards the depths of the Thunder Sea.

As soon as he entered the Thunder Sea, countless thunderbolts crackled towards the boat, and Tang Yu's scalp was numb, and he almost abandoned the boat and fled. Out of trust in Yu Chengxuan, he didn't move.

The boat is like a magnet, attracting countless lightning strikes. At the moment when the thunder and lightning were about to slash Tang Yu, a faint light shield lit up around the boat. The lightning struck on it, like a slippery soap, and slipped from the mask without causing the slightest harm to the people in the ship.

At this time, Yu Chengxuan finally finished charging his energy, and said lightly with his free hand: "This boat is built of thunder wood, and thunderwood is a kind of tree that grows in the thunder sea. This kind of wood has a special function, which is to guide mines. After the construction of the master foundry, engraved with a spiritual pattern, and by inputting spiritual power, this characteristic can be magnified several times, which can be used to build this kind of boat that can cross the Thunder Sea. I'm still quite small, and the City Lord's Mansion is big enough to transport people, and I can send two hundred people across the Thunder Sea at one time!"

Although Yu Chengxuan said that the boat was small, he couldn't hide the smug look on his face. It seems that this so-called Thunderwood is not so easy to obtain.

As the boat deepened, the thunder and lightning became stronger and stronger, and Tang Yu felt a slight tremor on the boat. At this time, Yu Chengxuan's expression was not as relaxed as before, and he concentrated on transmitting spiritual power to the wooden platform.

Looking at the thunder and lightning outside the ship, Tang Yu couldn't help but sigh: "The thunder and lightning are so strong, does there really exist an island in this thunder sea?"

Hearing Tang Yu's exclamation, Yu Chengxuan turned his head and said with a smile: "Not only that, but there are many of them!" There are countless small islands in the Thunder Sea, and the sand and gravel of these islands are no different from Guya City, but for some reason, thunder and lightning just don't split those places!"

"So amazing?"

"It's so amazing!" Yu Chengxuan nodded and continued: "I'm telling you a secret, in this Thunder Sea, every island discovered has some strange places, so they are all occupied by various forces. If you can find a small island without an owner, then congratulations, you have sent it! The island of Totsuki that we are going to is considered ordinary among them, and some of the large islands are considered a small continent in size, and the things on it are even more amazing, but I haven't seen it yet!"

"Then there are no native creatures on these islands? It stands to reason that there should be some spirit beasts or something in such a large area. ”

"Yes!"

Yu Chengxuan nodded heavily, and said with a solemn expression: "I told you that the most dangerous thing in the Thunder Sea is this sea, but in fact, this is not rigorous. To be precise, the most dangerous are the various demon beasts above! Among them, the lowest level is the creatures on the island, some of which are not inferior to the powerhouses of the gods, and because of the thunder sea, these demon beasts are not very easy to use, and they are very violent!"
