It wasn't until this time that the beluga whale figured out that the small animal with long limbs and poor body streamlining on the other side was very powerful, and it was not something that a sea creature like it could handle, so it could only be obedient, at least it thought it had figured it out by itself.

After subduing the beluga whale, Ziyan also took out some pills and fed it. The beluga whale never knew that there was such a delicious thing in the world, and was immediately completely convinced, and said that he would follow the two of them and be their faithful little brother. Tian Xu thought that the two of them were swimming at the bottom of the sea for a long time, and it was not interesting, with the beluga whale, there was also a companion on the road, which could relieve the loneliness, and he took the beluga whale to swim along the submarine mountain range to the northeast.

The length of this submarine mountain is not too long, only 100 kilometers long. The two of them watched the scenery along the way as they advanced, and soon reached the end of the mountain. Along the way, Tian Xu easily collected many undersea creatures into the Medicine King Bucket.

In addition to ordinary animals and plants, Tian Xu also found traces of several demonic beasts in this mountain range, most of them were electric eel demonic beasts, but they did not reach the level of the one he first caught, and they were swept away by him. In addition to the electric eel, there was also a third-order demonic beast shaped like a fish and a small group of second-order demonic beasts like squid, which he easily put away.

After the end of the submarine seamount, there is a deep sea of more than 1,000 meters ahead. Tian Xu had no intention of exploring the bottom of the sea again, and the beluga whales had limited diving time, so they no longer dived, but only advanced dozens of meters below the surface of the sea.

When the diving formation used by Tian Xu and Ziyan advanced below the surface of the sea, it was much faster than on the surface of the sea, and the same was true for the beluga whale. The reason is very simple, there are waves on the sea surface, and it is easy to form turbulence with strong resistance when swimming, which can reduce the speed by nearly half, and it is even more serious at high speeds. They effectively avoided this problem by advancing below the surface of the water.

However, although they did not dive to the bottom of the sea again, Tian Xu's olfactory imaging was able to cover the bottom of the water below them, and they had a basic grasp of the underwater situation.

Proceeding at such high speed without distraction, it took them only one day to reach a relatively northerly position in the Sea of Japan.

Tian Xu had intended to cross the Soya Strait at the northeastern tip of the Sea of Japan, then head north along the Kuril Islands, the dividing line between the Khovintsk Sea and the Pacific Ocean, and then across the Pacific Ocean along Kamchatka and the Aleutian Islands to Alaska.

When he was still dozens of kilometers away from the Soya Strait, Tian Xu unexpectedly received a long-wave communication signal, which aroused his strong interest.

For a long time, Tian Xu has been studying the electromagnetic wave signals of this long-wave communication, as well as the problem of bioelectric fields.

As far as he knows, if he wants to communicate on the seabed, which has a huge shielding effect, he can only use long-wave, but his research in this area has not made good progress, and the difficulties lie mainly in two aspects.

One is that his body is limited in length and is not able to operate collectively to form controlled long waves like a scallop swarm. He can use the Psychic Realm to assist in this process, but this will cause electromagnetic waves to oscillate within the Realm, affecting his control of the Realm.

On the other hand, the electromagnetic waves that he barely emitted can only be emitted at the same time in all directions without distinction, so that with the extension of the transmission distance, the attenuation of electromagnetic waves is very serious, and the distance that can be transmitted is seriously limited.

The long wave he received this time had obvious regularity, and it was obviously emitted by humans. He guessed that it was a technological product of the secular world. He couldn't decipher the contents of the electromagnetic wave, but it didn't stop his keen instincts from sensing the anxiety of the signal.

This set of signals happened to come from the direction of the Soya Strait in front of him, which was in line with his planned direction, so he led Ziyan and Moby Dick Bai Yuan to rush in the direction where the signal came from to see what was happening at that time, and also observe the transmission pattern of the long wave by the way.

Bai Yuan is the name that Moby Dick chose for himself. At that time, Ziyan wanted to give Beluga a name, and the name she came up with was Xiaobai. After Moby Dick asked the meaning of the name, he decisively refused, and then gave himself the name Bai Yuan. Along the way, this name has been called by Tian Xu and Ziyan, and Bai Yuan can already understand the name they called out with sound waves.

After swimming out for a while, Tian Xu determined the source of this long wave, which should be on the bottom of the sea 2,000 meters in front of them. His olfactory imaging could not perceive such a long distance on the ocean floor, but they had received the same long-wave signal three times on the way here, and the signal strength and transmission angle had changed, and they could basically determine the location of the signal.

At the same time, louder and louder knocking sounds made it clear to them that something was happening in the place where the electromagnetic waves were emitted.

Intuition told Tian Xu that things ahead might be urgent, so he no longer waited for Bai Yuan, who was relatively slow, and rushed towards the place where the sound came from with Ziyan at full speed. After swimming a short distance, the scene in front of him had already entered the perceptual range of olfactory imaging, and Tian Xu finally saw what was happening.

A huge submarine painted black is lying on its side on the bottom of the sea at a depth of more than 200 meters, it seems that it has lost its ability to move, and the culprit who caused the problem of this submarine is busy attacking the behemoth in front of him that has lost the ability to resist, which are two huge octopuses.

It may not be appropriate to say that it is an octopus, because on closer inspection, the difference between these two things and an octopus is quite obvious. Like an octopus, both animals have only one head-like body, but this one is not as round as the octopus's head-like body, it is obviously longer, and it bends horizontally from the rubbing, forming a brain gate like Shou Xinggong, which looks a little weird.

What's even more peculiar is that this guy has four eyes, not on the head like an octopus, but on four long stalks that grow from the top of the head, and can turn in all directions independently.

Their long tentacles are very similar to those of octopuses, only longer, but only six. At the end of each tentacle, there is a fork that becomes like two fingers.

This strange octopus has a head less than a meter in diameter and a height of nearly two meters. The six tentacles were more than fifteen meters long, and the two monsters were wrapped around the head and tail of the submarine, as if two huge monster hands had grabbed the submarine at the same time.

The most amazing thing is that these two "giant hands" are not going their own way, but are working together sincerely and are trying to break the submarine apart. They apparently couldn't do that, and after some hard work, the two monsters began to work together to lift the submarine and smash it against the rocks at the bottom of the sea.

On these two strange octopuses, Tian Xu clearly felt the cold aura of the demonic beast, there is no doubt that these are two demonic beasts. Judging from the operation of the aura on their bodies, these should be two fifth-level demonic beasts.

The submarine that creates all kinds of evil with secular technology is still relatively powerful, and it has been more than ten minutes since he received the submarine's long-wave distress signal, and under the full toss of these two fifth-level demonic beasts for so long, they have not been broken yet.

Tian Xu didn't know if the people in the submarine were still alive, as long as the demonic beast didn't use strong sound, electricity and other long-range attack methods, the problem shouldn't be too big. Since the submarine is still intact, the possibility of survival of the people inside is still quite large.

Judging from the attack methods of these two large octopuses, they seem to be only good at physical attacks, and at the same time, the two octopuses can cooperate quite finely, which also adds a lot of points to their combat effectiveness.

Tian Xu and Ziyan's high-speed swimming a few hundred meters away was quickly discovered by the octopus, they let go of the submarine at the same time, each took a large mouthful of water, and then the six claws landed alternately, and quickly greeted Tian Xu and Ziyan from the bottom of the sea.

Tian Xu's olfactory imaging searched the tentacles of the two octopuses, and found that there were three bony hook-like things inside the bowl-sized suction cups on their tentacles. If you are touched by them, it is estimated that it will not be comfortable.

The two big tentacles more than ten meters long climbed the rocks at the bottom of the sea, moving quite fast, Tian Xu estimated that they could reach more than 40 meters per second. He guessed that this should not be their fastest speed, and immediately reminded Ziyan to be careful.

Unexpectedly, Ziyan said: "Look at these two guys, they should be powerful magical beasts, such guys basically have no other spells, just like the flying crane camel, just give me practice." "Since she practiced the technique of chasing the sun, she has never relied on the practice of physical combat, and when she saw these two big octopuses at this time, she couldn't help but itch.

The two separated slightly, preparing to deal with an octopus each, and the two octopuses also tacitly rushed towards the two of them, and before the body arrived, two long tentacles each stretched out far away.

Just a moment before engaging the enemy, Tian Xu's olfactory imaging suddenly smelled an uncomfortable special smell, and hurriedly reminded Ziyan: "Ziyan be careful, this thing will release poison." ”

Ziyan has Tian Xu's refining diving formation to protect his body, and his body is isolated from the surrounding seawater, and he doesn't care too much about the poisoning of the octopus, so he only says: "Got it." She drew her sword and struck at the octopus that was near her.

The two tentacles of the octopus on the opposite side intertwined gently in front of her, wrapping around her waist and neck, respectively. With a swing of his feet, Ziyan's body accelerated suddenly, and he rushed past the tentacles before they reached his body, and slashed at the intersection of the two tentacles, cutting off a third of both tentacles.

The severed tentacles retreated at a rapid speed like an electric shock, leaving only one tentacle to land on the ground, and the other three tentacles surrounded her from different directions at the same time.
