After separating from the others, Fang An began to dive all the way to the depths of the heavy water ocean, relying on the power of his vast divine consciousness to help, it was quite convenient to search for the essence of heavy water.

It's just that along the way, the essence of heavy water encountered is only the size of a fist, and the power contained in it is really too weak, which is really a drop in the bucket for Fang An.

However, according to the experience of opening the Heavy Water Secret Realm in the past, the deeper you dive, the greater the chance of encountering a large Heavy Water Essence.

Therefore, Fang An didn't bother to touch these fist-sized heavy water essences anymore, but instead began to accelerate towards the bottom of the heavy water secret realm, wanting to find a bigger heavy water essence.

This time, the opening of the Heavy Water Secret Realm is still relatively friendly to these participants on Thousand Star Island.

Because every time the Heavy Water Secret Realm is opened, the location of the entrance to the space is not fixed, and this time the entrance is not too deep in the heavy water ocean, so the pressure of the heavy water is not too large.

And more than 3,000 years ago, when the heavy water secret realm was opened, because the opened space entrance was located in a place that was tens of thousands of miles away from the sea surface, so when that group of 100 spirit masters just entered the heavy water secret realm, they directly turned into blood sludge under the huge water pressure and dissolved in the heavy water secret realm.

After this battle, these ten island masters on Thousand Star Island learned to be obedient, and began to personally send the spirit master into the heavy water secret realm with the power of divine sense, once they found that the water pressure was too high, they would terminate this secret realm exploration and prevent these disciples under their command from dying so casually.

Of course, this kind of thing is still very rare, at least in the 20,000 years since the Heavy Water Secret Realm was discovered, there has only been one time.

Generally speaking, if the entrance to the heavy water secret realm space is opened in the heavy water ocean, the depth will basically be within two thousand miles, which is also the limit that these spirit masters on Thousand Star Island can bear.

And this time, the entrance of the space was only ninety-seven zhang away from the sea, and it was less than a mile, Fang An's divine sense swept upward, and it happened to be able to penetrate the sea, which could be said to be very lucky.

In the past, when the Heavy Water Secret Realm was first discovered, there were naturally many spirit masters who dived into the sea and wanted to explore the entire Heavy Water Secret Realm.

However, after a hundred spirit masters wandered in different directions for two months, there was still a sea of heavy water as far as the eye could see, and the sea was as calm as a pool of stagnant water, and not even a single island was found, let alone plants and animals.

After several times, the result is still the same, as if in this great heavy water secret realm, there is only heavy water and nothing else.

Later, when the essence of heavy water was discovered in the ocean of heavy water, these spirit masters who entered the secret realm of heavy water were ecstatic, and finally stopped wasting time exploring the surface of the sea, and instead began to go to the sea to find the essence of heavy water and enhance their cultivation.

The diving process was very boring, even if Fang An's divine sense could sweep a hundred zhang area, the visibility of the naked eye was still not high, and the eyes were all filled with the blue light unique to heavy water.

Ignoring the heavy water essence that wandered around him from time to time, Fang An dived vertically downwards with his head under the impetus of his spiritual power.

At this depth, the Heavy Water Essence encountered was only the size of an adult's head, but in the depths of the Heavy Water Ocean, there was a Heavy Water Essence that was thousands of times more powerful than it was waiting for Fang An.

Sharpening the knife is not a chopping woodworker, Fang An still understands this truth, and when he goes down to a certain depth, he can casually catch a heavy water essence and absorb it, and the effect of quenching will be thousands of times stronger than now.

Diving all the way, as the depth increased, the heavy water essence that Fang An encountered finally began to grow larger.

Time passed, and after three days, Fang An came to about three thousand miles of the heavy water ocean.

Diving a thousand miles a day, this speed is already very amazing, even on land, to be able to travel thousands of miles a day can only be done by the best black horses, not to mention in the deep sea, resisting this huge water pressure and resistance.

The depth of the heavy water ocean is 3,000 miles, and this is basically the limit range that the spirit masters on the Thousand Star Island in the past generations can explore.

The pressure of the heavy water here is already extremely strong, and the spirit masters of the Immortal Three Realms of Leisure can't bear it at all, even the Thousand Star Island Spirit Masters who have the spirit of sea beasts believe that they will not be an exception.

But for Fang An, these pressures were still within an acceptable range, at least not even his protective spiritual power could be crushed.

Thanks to the fact that the spatial entrance of the Heavy Water Secret Realm was opened at a depth of ninety-seven zhang in the Heavy Water Ocean this time, Fang An could use the power of his divine sense to accurately locate the depth he was in.

In the sea of heavy water, the power of Fang An's divine consciousness can spread a radius of 100 zhang, 166 zhang 6 feet 6 inches is one mile, according to Fang An's calculations, this place is 542,100 zhang from the sea level of the heavy water ocean, about 3,252 li.

At a depth of more than 3,000 miles, the essence of heavy water here is basically the size of two zhang, and the strength of the sea beasts transformed is also equivalent to about the three extraordinary realms.

For the current Fang An, the ordinary transcendent three realms no longer have any threat to speak of, not to mention that these sea beasts transformed by the essence of heavy water don't even have souls, so they are not intelligent beings, and they will not take the initiative to attack Fang An.

Only when attacked, these sea beasts will rely on instinct to fight back, in fact, this is just a way for the spirit of heavy water to vent their energy.

When the Heavy Water Spirit has finished venting its external abilities, the transformed sea beast will collapse, and the remaining Heavy Water Spirit Core will have no power to resist.

From this, it can also be seen how powerful the energy is contained in these heavy water essences, like this two-zhang heavy water essence, the illusion of the sea beast is already five zhang high. And just the energy that is stimulated and released has reached the level of the ordinary transcendent three realms.

You must know that if you go one step further in the transcendent three realms, you can already rank as the god of Kyushu in the outside world.

Of course, for Fang An, these heavy water essences are not enough.

Perhaps Qing Yu'er and the others could rely on this level of heavy water essence to cultivate the water kidney, but judging from the previous cultivation experience of the Fire Heart, if Fang An wanted to complete the cultivation of the first viscera, the energy required was more than a thousand times that of an ordinary spirit master.

If you want to rely on the cultivation of the Heavy Water Essence on a two-zhang scale, the amount required is probably not a small number, and the Heavy Water Essence is not easy to search, and it is estimated that two months is far from enough.

So Fang An decided to continue diving.

Three thousand nine hundred zhang, the pressure here has reached the limit that the transcendent realm can bear, and even the talisman spiritual power that Fang An has been exerting cannot withstand the test of water pressure, and it directly collapses in the sea of heavy water.

The huge water pressure broke through the barrier of spiritual power and slapped directly on Fang An's body.

With the sound of skin cracking, the clothes Fang An was wearing were directly cracked, and even the inner lining made of demon animal skins prepared in advance also "collapsed" under the water pressure, as if it might disintegrate at any time.

"It's a little uncomfortable. ”

The spiritual power disintegrated under the pressure of the water, and it was no longer even able to penetrate out of the body, feeling a slight stinging pain coming from the exposed skin, Fang An couldn't help but smack his lips.

For Fang An, who was still at the peak of the transcendent three realms, since he had not been able to step into the realm of transforming into gods in the realm of cultivation, his spiritual power naturally failed to produce quantitative and qualitative changes.

Therefore, compared to his physical body and divine sense, the current Fang An's spiritual power can be said to be the weakest part of his strength.

Before entering Fuyun Island, in order to kill the foggy sea octopus that had not yet become the demon king, the "sea splitting" swordsmanship took out the spiritual power in Fang An's body, which also showed that the spiritual power in Fang An's body was far inferior to the majestic transformation of the gods.

"Go on. ”

Fang An knocked on the back of his neck, relieving the discomfort of his skin and muscles after the sudden pressure, and then his legs suddenly kicked hard, and with the sound of "boom" explosion, Fang An's body broke through the heavy water turbulence like a sharp arrow, and dived rapidly.

Whoa!

The inner armor on his body made of the skin of a seventh-order sea fish demon beast finally couldn't withstand this sudden increase in strength, and it scattered into a few pieces in a few "bang" sounds, floating alone in this deep sea, and was thrown away by Fang An.

The sudden exposure of his body made Fang An feel a little uncomfortable, but he was quickly relieved.

Anyway, except for a few foreign spirit masters in this heavy water ocean, the rest are lifeless heavy water spirits, and he is not afraid of being seen by the energy mass in the shape of these sea beasts.

What's more, at a depth of four thousand miles below sea level, it is estimated that those spirit masters of Thousand Star Island will not be able to dive, even Qing Yu'er and others, who have already reached the peak of the transcendent Three Realms, believe that it will be difficult to hunt here for a long time.

Although several of them had cultivated the immortal golden body taught by Fang An, their physical bodies were already close to the powerhouses of the realm of transforming gods, and even their physical bodies might have reached the realm of transforming gods, but compared to Fang An, they were still a little inadequate.

The dive continues.

Four thousand five hundred miles······ 5,000 miles······ 5,500 miles······ Six thousand miles!

In the end, Fang An stopped at a depth of seven thousand miles in the heavy water ocean.

Looking down, there was still a blue heavy water in the eye, and Baizhang Divine Sense did not find any rocks, obviously at a depth of seven thousand miles, it was far from reaching the bottom of the heavy water ocean.

Fang An stopped because the water pressure here had already caused some tiny cracks to appear in his skin, but before the brilliant golden blood could flow out half a thread, the wound had healed again.

Of course, this scar was nothing to Fang An's physical body, and Fang An estimated that if he continued to dive, there would be no problem at least reaching a depth of 10,000 li.

Unless the depth of this heavy water ocean is not 10,000 miles.

The reason why he stayed in this place for seven thousand miles was mainly to facilitate the hunting of the essence of heavy water.

Compared with the 3,000 li under the sea, the 7,000 li here is only more than twice as deep as the difference, but the size of the heavy water essence is more than 20 times.

The core of the heavy water essence with a size of more than fifty zhang appeared in front of Fang An, and the body size of the sea beast that was transformed was obviously more than a hundred zhang, like a shrimp and a fish, with a strange shape, like a blue lantern in the sea, very dazzling.

Even the Kirihai octopus that I encountered before did not reach this level in size.

With such a huge size, it is estimated that the strength is already comparable to the realm of the gods.

The power of divine consciousness was mobilized, and Fang An fixed the water into a sword, and then controlled the huge heavy water sword more than ten zhang long, stabbing directly towards the sea beast in front of him.
