After the days on the island finally became boring, Luo Yu had to find a way out from the piles of sea dao books in the storage bag, but he also found some unexpected deviations.

One of the 'day-by-day methods' can be based on the position of the two stars of the sun and the shade, and use the star chart to calculate the location of the vicinity against the sea chart, this method is too complicated, and during the dark clouds and sun-obsessed weather, you have to start all over again, even if Luo Yu is also a very patient person, but I really can't raise the slightest interest in seeing this method.

Luo Yu also tried other methods of chasing seabirds and observing reef species.

It's just that all the seabirds on the island leave at sunrise and return at sunset, and the farthest time is only to fly to another group of islands and reefs more than ten miles away for half a day, and then return again, and the islands and reefs are also desolate and primitive, there are really no clues, and there is no need for seabirds to lead the way, Luo Yu flew out of a hundred miles in one breath when his body recovered from his injuries, and he already knew the existence of this island and reef.

Considering the lack of mana and the consumption of too much, he had to go back.

Although it was not Luo Yu's limit that time, he still couldn't find other islands with people a hundred miles away with his divine sense, which could only show that the sea area where he was located was very likely to be some border sea area mentioned in many ancient books.

Luo Yu didn't feel strange that he would fall in such a place, because as far as he knew, the four seas were too vast to really explore the boundaries of the seas, even if the top immortal cultivators in the four seas were gathered together, they couldn't do it.

Because it is just a random sea city in the four seas, it is also the smallest shroud of nearly 10,000 miles of sea territory, and it is possible to cover hundreds of thousands of miles or millions of miles in a large area, and among them, the human race, demon race, and spirit race are all gathered in a certain sea area centered on Haicheng and Haizhen, so the sea frontier controlled by Haicheng and infested by monks is mainly concentrated in certain places, even if it is extended in these places, it is really insignificant compared to the sea frontier of 10,000 miles.

Therefore, from ancient times to the present, there are a large number of unknown sea areas in every sea frontier, and the so-called border barren sea area or 'ancient sea' in the four sea areas refers to such a place.

The sea area is so large, many immortal cultivators have devoted their lives to being able to understand the sea frontier they are in, which is already very good.

The only thing that can be specifically described is that the four seas mentioned in the ancient road book are divided into one hundred and eight cities, which are distributed in various places in the four seas, each sea city controls an incomparably huge sea territory, they may be adjacent to each other, or they may be far away, if you want to know how big the four sea areas are, you can estimate the number of one hundred and eight sea cities, but I believe that the answer drawn in this way will not be true.

Therefore, the sea area where Luo Yu is located must be an ancient sea area in the sea territory, so it can explain why the vicinity is deserted, and if you want to go out from the ancient sea area, unless you know the route to the nearest human sea area in advance, the best way is to wait.

Only when some immortal cultivators happen to pass by can there be any possibility of leaving, and what makes Luo Yu's heart feel better is that situations similar to his occur from time to time in the overseas immortal cultivation world, and there is still a chance of encountering other immortal cultivators.

After all, in the thousands of miles of sea territory near Haicheng, it is a sea area where the three clans of spirits, demons and demons are intensively ruled, and a large number of cultivation resources have long been exhausted, and it has almost become a must-do for sea cultivators to go out to the ancient sea to explore the ancient sea, Luo Yu just doesn't know when someone will come to this sea area for training.

But judging from his many explorations of the surrounding seas, the situation is not so optimistic, with the desert island as the center, none of the sea monsters have been found, and that's it, the most existing in the four seas is not the demon beasts but the sea beasts!

But Luo Yu was immediately depressed to find that the number of Tribulation Sea Beasts in the nearby Hundred Miles Sea Frontier was also extremely rare, not to mention that the spirit veins on the only few islands were sparse and weak, and it was impossible to grow rare elixirs.

Luo Yu is naturally not a person who is waiting to be killed, and as he gradually became familiar with the grass and trees around the island, he slowly came up with some ideas.

Since there are some things that he doesn't have to create by himself, he first arranged the induction formations on various islands and reefs, and set up the main formation on the desert island he is on, once there are immortal cultivators flying over the hundreds of miles of sea around him, he can find it as soon as possible.

This is just one of the steps, Luo Yu put many unused high-level and low-level magic weapons on his body into the belly of some sea fish and a few first-order sea beasts, if these sea beasts are hunted and killed by monks, the other party sees the magic weapon treasures in the body of the sea beasts, and they will inevitably think of some treasure troves or ancient monk caves, so it is inevitable that they can't help but trace the source of these sea beasts.

Although Luo Yu did not hesitate to make full preparations, this difficult wait still lasted for more than two months, and finally one day!

On this day, Luo Yu had just finished releasing a sand tooth fish, and it was a pity that a high-level fire attribute net-like magic weapon might be sunk into the sea, when suddenly a few muffled thunders and roars came from afar, and the beasts, birds, and birds on the originally peaceful island fled in a panic.

At the same time, the sea in the extreme distance immediately set off a wave several feet high, and the naked eye can see a layer of white smoke waves sweeping rapidly, and the waves crashed on the nearby reef with a thunderous sound.

Although Luo Yu had long been accustomed to the fact that the sea had no wind and three feet of waves, it was the first time that such an unusually abrupt change had occurred.

Monsters!

Before he could figure out what was going on, Luo Yu was stunned and almost couldn't hold back his ecstasy, and the mood that had been suppressed for a long time suddenly shocked his spirit.

It must be known that demon beasts are different from sea beasts, the latter is born with a strong sense of territory, and will not easily leave the environment of survival, even if there is a foreign enemy intruding, they will only fight to the death.

Demon beasts are different, they are naturally cunning and changeable, and most of them are afraid of the soft and the hard, once they are defeated, they will immediately flee, and Luo Yu has long been familiar with the situation in this area, and there are no demon beasts nearby!

What's more, judging from the roar of this demon beast, it is obvious that it has encountered a strong enemy and has been chased and killed!

Just as Luo Yu was suspicious and released his divine sense to look into the distance, this time he heard it more clearly, and a louder roar like the neighing of a horse actually came from the rolling smoke and water waves.

At the same time, Luo Yu's powerful divine thoughts also pierced through the water curtain in an instant, and he saw the true face of this monster beast that was making trouble.

Hidden inside is a two-headed seahorse that is stepping on the water column, riding the wind and waves, its ears are shaped like agate, its body is unusually large and comparable to a giant elephant, the two heads are fiery red and sky blue, and the body is covered with bright brown bone fragments, and the most peculiar thing is that the eyes of this beast can alternately emit four kinds of light!

It was the first time Luo Yu had seen such a rare strange horse demon beast, and he couldn't find any origin of this beast in his impression, but the cultivation of this beast was very ordinary, just a second-level demon beast.

But Luo Yu didn't really care about these, he didn't mean to stop this seahorse demon beast at all, but his eyes and divine thoughts were cast in the direction behind the demon beast, and his body was quietly unfolding in the pale golden yuan sea, so he hid it and observed.

Soon, as expected, there was a blue-yellow cloud-like escape light that caught up with this seahorse demon beast within a moment of its appearance.

"It's an immortal cultivator! With such a voice, this is indeed the Thunder Sea. In the sea of knowledge, Luo Yu's divine mind saw the three figures inside through the oncoming light, and the gap between the two sides actually made him hear the conversation of the three people, and he was already proficient in the languages of the four seas in the black domain, and suddenly judged that the general sea area where he was now appeared, which was not much different from his original analysis.

At present, the appearance and dress of the three people can't escape Luo Yu's prying eyes, they are a woman in a small shirt with a bare arm and two tall and thin young men.

Among them, the tall woman drove a blue lotus-shaped flying magic weapon, floating on the surface of the sea and also breaking through the waves, quite similar to the water escape technique performed by the two-headed seahorse.

It seems that this woman is only in charge of chasing, and the other two men with several yellow flying swords around her are the real ones who attacked.

Among the three of them, the woman in the small dress and green dress has the lowest cultivation and is only in the early stage of foundation building, and the other two are both monks in the middle stage of foundation building, and the cultivation of the three people is naturally not in Luo Yu's eyes, but the red crown on the head of the two tall and thin young men, the style of the red tassel rope hanging down from the two plates, has been faintly seen.

Just for a moment of distraction, the two-headed seahorse passed by Luo Yu in mid-air without noticing, and the three people who followed closely were only dozens of feet away from the demon beast at this time, and the two sides didn't notice that Luo Yu was hiding nearby.

At this time, the two men seemed to realize that the time had come, and after exchanging a look, they patted their respective storage bags, and tacitly took out a cyan flying fork, with runes entwined on it, and there were bursts of green light beating at the tip, and at a glance, they knew that it was not ordinary.

The two of them almost didn't need to discuss at the same time to urge the spiritual power to decide, and suddenly the cyan flying fork rose to more than two zhang long in the wind, making a 'buzzing' trembling sound, and then the flying fork was thrown away by the two of them to the sea under their feet, and when the two blue lights were still in mid-air, there was a strange sound of water rolling up, and in a blink of an eye, it was like a dragon entering the sea and disappearing on the sea in an instant.

Except for the evasive waves that chased and fled one after another, there was no movement in the nearby sea, as if the two cyan flying forks had sunk to the bottom of the sea.

Just when Luo Yu was curious if the two of them were not throwing in the direction of the demon beast, he suddenly turned around and looked at it with a moving expression!

The two-headed seahorse, which was only more than ten feet away from him, was just about to fly over a calm sea surface in a panic, when two green rainbows suddenly shot out from under the water, and stabbed upwards like crossbow arrows with a piercing whistle that broke through the air.

The seahorse demon beast was originally flying away against the water, and it suddenly didn't have time to dodge, so it hit the edge of the blue light impartially, and two thunderous explosions were immediately released.

The water mist set off by this beast is at most effective against some low-level spells, and when it encounters this ancient artifact or a complete set of treasures, it can hardly play any defensive role, and the fleeing seahorse demon beast is only guarded by a layer of blue water vapor light shield transformed by demonic power outside its body, but it is not the strongest means of life-saving, so as soon as it touches, the shield trembles wildly and shows the appearance of cracking, and then the blue light destroys the decaying hole and passes through the water cover!

A terrible hiss suddenly came from the rolling mist!

Almost at the same time, the surprise laughter of the three people also sounded in the yellow and blue light behind them!

"Quick! The two senior brothers must not hurt it, they must be captured alive!"

"Haha, don't worry, this beast has been hit by the 'green chain fork' of the two of us, and it can't run if you want to. ”

Luo Yu looked at the three of them coming excitedly and eagerly, and had already regarded the two-headed seahorse as a meal on a plate, and recited a few words of 'green chain fork' in his mouth, and couldn't help but look carefully at the injured demon beast.
