After finishing their visit to the Gathering Spirit Array, the two returned to the Twin Volcanic Islands along the same route. Tian Xu did not destroy this Spirit Gathering Array, God knows if this Spirit Gathering Array will still play a role in fighting against the attack of demonic beasts in the future, and it is better to keep it.

However, for the elixir on the Twin Volcanic Islands, he would not be polite, and honestly and unceremoniously transplanted all the elixirs into the Medicine King Bucket.

At this time, the two kinds of fog that permeated the island had dissipated, and Tian Xu's original idea of taking a part of it for research had also failed, and he didn't have the patience to wait here, waiting for the next outbreak of fog, so he gave up the idea of collecting fog and embarked on a journey to move on.

They have already swam more than half of the Kuril Islands, and there are three islands in front of them to reach the end of the archipelago, Kamchatka. The three islands are almost in a straight line with the southern tip of Kamchatka, and the distance is only a few hundred kilometers, and they can reach Kamchatka in a maximum of four hours without a detour.

They had just swam more than 30 kilometers when Tian Xu suddenly heard a special high-frequency vibration coming from the sea behind them. His olfactory image, which had been mainly extending forward, unfolded behind him, and immediately noticed that something was chasing them at high speed from behind.

The two of them were already swimming at a speed of nearly 200 kilometers per hour, but he didn't expect that something in the sea could catch up from behind him at a faster speed, which couldn't help but attract his attention.

Under the careful observation of olfactory imaging, Tian Xu found that the thing he chased was not too big, about the same size as a person, the whole was cylindrical, and the seawater flowed through the hollow part of the cylinder, and sprayed out continuously at high speed backwards, reaching a very fast speed by the reaction force of the water spray. Tian Xu estimated that the speed of this thing had reached more than 250 kilometers per hour, and even if he was desperate to move at full speed, he might not be able to reach such a speed.

The aura on this thing's body is restrained, and there is no overflow, but it is extremely condensed, and it is obviously not an ordinary sea creature. When it got closer, Tian Xu could already feel the weird and tyrannical demonic aura on its body, this should be a powerful ocean demonic beast. Tian Xu couldn't judge its level for a while, but judging from its performance, this was at least a demonic beast between the peak of the fifth level and the sixth level, and he had to deal with it carefully.

At this point, the two of them stopped moving forward, but stopped and waited for the arrival of the demonic beast.

The speed of the demonic beast was very fast, and it soon came to a kilometer away from the two of them, and before the body arrived, a message of thought had already been transmitted first: "Human cultivator, you stole my elixir, do you want to escape like this?" It didn't wait for Tian Xu to answer, and continued to rush over at high speed.

This thing is extremely fast, capable of advancing more than seventy meters in the water every second, and it only takes more than ten seconds to reach the two of them. It didn't stop at all, and slammed straight into the two of them.

At this time, the two of them had already seen the appearance of this thing. It resembled a carapace cylinder, a little over a foot in diameter, a meter and a half in length, and a wall about a centimeter thick, with sharp edges at the front and back ends, and sharp serrations, which spun at high speed and hit it head-on.

When this thing was still more than thirty meters away from Tian Xu, Tian Xu's directional shock struck it head-on, wanting to test its strength.

Directional concussion is the first technique obtained after Tian Xu Ning Dan, the principle is not complicated, it has been used many times on land, although the suddenness of the attack is strong, the enemy has been hit many times, but the power is not satisfactory, it is difficult to hurt the opponent of the same level.

However, this does not mean that directional oscillation is not very powerful in water, in fact, this technique is designed to fight enemies in water.

At this time, this directional shock attacked the past, and the demonic beast on the opposite side ate the blow head-on without reacting, but it did not hurt its muscles and bones, and with a "pop" sound, it shattered the shock condensed by Tian Xu in front of him, and then continued to rush towards them, but under the obstruction of this directional shock, the speed dropped by more than half.

After the demonic beast broke through Tian Xu's directional shock, he couldn't help but be careful, it seemed that the two human cultivators in front of him were not easy to deal with. It spewed a stream of water forward from the cylinder, stopping a few meters in front of the two men. When the water it spewed out towards the two of them flowed in front of the two of them, it was pushed by the fairing of the two of them and changed direction, passing past the two of them, while Tian Xu and Ziyan were motionless, not pushed by the unexpected flow of water at all.

Such a close distance had already entered Tian Xu's spiritual realm, and this mere flow of water could not shake Tian Xu at all. The demonic beast didn't know about the existence of Tian Xu's spiritual realm, and when he saw that the two of them were not shaken by the current, he was quite surprised, and couldn't help but let out a soft cry of "poof".

Tian Xu's spiritual realm is extremely sensitive, but at this time, he has clearly detected that the other party is a pure spiritual gas, this cylindrical carapace is just a prop for it, or it is more appropriate to say that the opening is more appropriate, this should be an earth immortal-level demonic beast, according to the classification method on land, it should be more appropriate to be classified into the category of sixth-level demonic beasts.

The aura body of this monster is not located inside the cylindrical carapace as most people imagine, but outside the carapace, and does not have the shape of limbs like ordinary beasts or humans, but is round and round, like a mollusk, sticking to the outside of the cylinder, forming a lump of bulge. Tian Xu guessed that this thing should have been some kind of mollusk that was accustomed to this amorphous state before it ascended, so it still retained this state after it ascended, but moved its body from inside the carapace to the outside of the carapace in order to confuse the enemy.

It's a long story, but it's actually just a momentary occurrence. At the same time that Tian Xu's domain detected the situation of the Demon Beast, the Demon Beast also launched an attack. The carapace cylinder that had just stopped suddenly lit up, and then a blue light lit up straight from it, shining towards Tian Xu. This was not a sword qi emitted like the two-body immortal toad, but a completely different form of energy—a laser.

However, although the distance of this demonic beast's attack was extremely close, only less than five meters, it was in Tian Xu's spiritual realm, and nothing escaped from Tian Xu's domain monitoring, and at the same time as the attack was issued, Tian Xu had already learned the form of this attack, and the domain gave the most reasonable means of response. A mirror quickly condensed in front of him, just enough to block the laser's blow and reflect it back.

Tian Xu's original intention was to shine the reflected laser on the body of the demonic beast and use it to injure the enemy. However, the direction in which the laser shot out of the cylindrical carapace was not coaxial with the cylinder, and deviated from the angle by one angle. Tian Xu's mirror was disturbed by visual common sense, and it was perpendicular to the cylinder, so that the reflected laser deviated from his expectations, and it could be grazed by the demonic beast on the opposite side, without hurting the other party. At this time, there happened to be an unlucky big fish swimming dozens of meters away, and it was illuminated by this laser, and it was vaporized in an instant and disappeared cleanly.

The demonic beast missed, and the aura body and the carapace quietly separated, destroying the carapace to rotate at high speed, rushing towards Tian Xu like a huge open-hole drill. And its aura body remained invisible, circling to Tian Xu's side.

Seeing that the carapace was weird, Ziyan's heart moved, and he wanted to draw his sword to attack, but was stopped by Tian Xu: "Ziyan, don't move! But he fell in love with this carapace, and was afraid that Ziyan would cut it off with a sword.

After the carapace was separated from the aura body of the demonic beast, it was just a spiritual weapon, although it was powerful, it was not a threat to Tian Xu at all. Tian Xu waited for it to rush in front of him, grabbed the sharp jagged edge in front of it, and put it into the Medicine King Bucket. In the face of the powerful power blessed by the Sun-Chasing Technique, the power of this carapace is like a toy, completely vulnerable.

Just when Tian Xu was dealing with the carapace, the demonic beast had already stealthily come to a position less than two meters behind Tian Xu, who was unconscious. It's just that before it can make a move, Tian Xu's realm has already been activated, making it difficult for it to move. The demonic beast realized that something was wrong and wanted to speed away from Tian Xu's side, but Tian Xu's left hand had already stretched out backwards like lightning, grabbing its body in his hand.

However, the demonic beast is not easy to get along with, its body has no fixed form, after being caught, the second half of its body stretches out quickly like a spirit snake, and suddenly wraps around Tian Xu's arm, wrapping his left hand and forearm.

There were thousands of small thorns on the body of the demonic beast, which were as thin as a cow's hair, extremely sharp, and Tian Xu's body after being improved by the Sun Chasing Jue was even powerless to stop it, and it was directly pierced. Tian Xu didn't notice it for a while, and he was tricked.

These small thorns have a special toxicity on them, a neurotoxin similar to anesthetics, which causes Tian Xu's left hand to be quickly paralyzed, and soon the demonic beast will be out of his grasp.

This toxin is not the kind of aura with a special brand, but a special chemical quality, which acts on nerve conduction, affects the conduction of bioelectricity in the body, and is very compatible with the aura. Tian Xu estimated that this toxin had a strong effect on cultivators before ascension, but for the earth immortals who had changed their aura bodies, the effect would be much weaker. Because the cultivators before the ascension, the nerve conduction in the body was carried out by electrochemical reactions, while the aura of the earth immortal body no longer relied on chemical solutions, but was achieved through the action of electric fields, there was an essential difference between the two, and it was unlikely that this toxin could be universal.

From this point of view, it was only a matter of time for the sixth-level demonic beast in front of him to enter the Earth Immortal Realm, otherwise he would not have used this kind of method that was not suitable for high-level opponents. This toxin should have been present before its ascension, and it was not willing to abandon it after ascension, and it was retained.
