Looking at the deep dark sea hole, Qin Shiou couldn't help swallowing his saliva.

Since he got the heart of Poseidon, he has maneuvered in all oceans. His mood is either curious or calm. There has never been a trace of panic like this moment.

Qin Shiou knows something about the ocean blue cave. This geology belongs to the calcareous platform, which was formed 130 million years ago. In the ice age two million years ago, the cold climate frozen water in the earth's ice caps and glaciers, resulting in a sharp decline in sea level.

Because of the alternating erosion of fresh water and sea water, many karst cavities will be formed in the calcareous zone. The location of the Blue Cave was once a huge cave. The porous and loose calcareous dome collapsed one by one due to gravity and earthquake, becoming an open shaft.

In this way, when the ice and snow melt and the sea level rises, the sea water will pour into the shaft, forming a strange blue hole embedded in the sea.

However, due to the characteristics of calcareous geology, the opening of this cave will not be very large. For example, the most famous Blue Cave in Honduras is known as one of the world's top ten geological wonders, but it is only 400 meters in diameter and 150 meters in depth.

However, looking at the current submarine black hole, Qin Shiou looked around and visually observed that the diameter of the black hole was at least one kilometer. He was familiar with the color and seemed unfathomable!

Honduras blue hole is called the eye of the ocean. Qin Shiou looks here and feels that this black hole is the mouth of the ocean.

The giant demon was far away from the black hole and swam slowly around it. Its membrane continued to shrink and relax, and thick water columns ejected from its abdomen, pushing it to swim on the seabed like a rocket.

For the black hole, the giant demon seemed to be afraid. Ten tentacles held the mace tightly, and even the first forelimb, which was still in the recovery period, raised the mace.

After feeling the arrival of Poseidon consciousness, the giant demon relaxed, sprayed water to the bottom of the sea, and moved slowly forward by the power of his tentacles.

At this time, a shadow quickly swam over the head of the giant demon. Qin Shiou expanded the control range of Poseidon consciousness and found that a long tailed shark swam above his head, which relaxed his nervous mood.

He brought the long tailed shark back from the sea area of Binghuo Island, but this guy seems to have little sense of belonging to the fishing ground. Qin Shiou rarely met it after he came back. He thought it was going to the South Atlantic to avoid the cold, but he didn't expect to meet it here.

The long tailed shark swims very fast. After it appears, it swims in the water above the giant demon. Occasionally, it pours down, and its slender tail beats the sea water, producing circles of ripples.

The giant demon ignores the long tailed shark. In its recipe, this thing is just a slag.

But the long tailed shark wanted to provoke the giant demon. After swimming in the upper sea for a few times, he killed the giant demon when he didn't pay attention. His slender tail swayed quickly and rushed to the top of the giant demon.

The giant demon naturally couldn't bear the provocation of the long tail shark. Its eyes suddenly widened like a lantern. The membrane absorbed water and ejected. Ten tentacles dragged a mace to meet it.

Both sides are murderous. It seems that it is an endless war. Qin Shiou feels sad for the long tailed shark. It is certainly not the opponent of the giant demon. Even if the king squid does not use a mace, it can be easily killed by its own strength.

Long tailed shark and King squid are not heavyweight. The former is only 45 meters long, while the latter has more than 10 meters tentacles!

The two sides hit head-on. When the long tailed shark rushed down a distance and saw that it was about to enter the attack range of the king squid, it fiercely shook its tail, pulled up its body, shifted its direction, and swam straight ahead. It seemed that it wanted to escape.

The giant demon follows the long tailed shark forward. It is large and explosive, but its flexibility is far less than that of the long tailed shark.

The long tailed shark obviously knew this. It swam forward with the giant demon for a kilometer or two, then changed direction, lowered its head and plunged into the sea bottom.

The giant demon who wanted to kill the long tailed shark followed, covered the membrane to absorb water and spray water again, and bowed his head to the downstream.

The king squid moves forward by the reaction force of water spray, which is doomed that it does not have strong continuous movement ability. It needs to stop for a short time after a fast movement, and can accelerate only after absorbing water and spraying water again.

The long tailed shark ran smoothly all the way. It bent down for a distance, suddenly pulled up its body, shook its tail with the fastest speed, and swept forward crazily, faster than before.

At this time, it is not so easy for the king squid to change direction. It is like a mine, roaring to the bottom of the sea. After a certain distance, it loses its power and stops in the water for a short time

Qin Shiou suddenly felt that at this time, the giant demon suddenly became very nervous. His tentacles opened and waited for Dan!

Looking down from the giant demon's eyes, Qin Shiou was surprised to find that the king squid was in a strange position at this time, just at the edge of the huge black hole!

At this time, the water around the black hole was boiling, and suddenly there was a wave. A huge monster circled out of the water and rushed towards the king squid floating at the mouth of the black hole.

At this time, the giant demon is in the state that it has just sprayed the water column and has not absorbed the sea water. At this time, its movement force is the lowest, and the monster rushed out is very fast. It spirals forward and climbs out along the four walls of the black hole. Then its body shrinks and attacks the giant demon.

This scene greatly surprised Qin Shiou. He took a breath and looked at the scene in shock: what monster is this?!

The thing rushed out of the black hole is very long, very big and flat. It is a bit like a centipede. Its body is flat and connected in pieces, but its pieces of body are very large. One piece is two or three meters long and one meter wide.

And the one-time appearance, there are more than ten or twenty pieces, a full 30 or 40 meters long, showed in Qin Shiou's vision!

The giant demon calmed down at this time. Obviously, it was not the first time to fight with the monster. In the face of the fierce opponent, it stretched out ten tentacles and wound up subconsciously.

The most terrible thing about King squid is this kind of death entanglement battle, because their tentacles are too strong. Even a small boat can be crushed. Ordinary opponents such as whales and sharks will almost die if they are entangled.

But the monster was not afraid. After the giant demon's tentacles were wound, its body turned over and even wound the giant demon. Then the giant demon trembled in pain, and there were many ferocious wounds on its body!

Qin Shiou screamed bad. He hurried up to control the monster and wanted to let go of the giant demon, but something frightened him happened - he couldn't control the monster, or he felt that he had controlled the monster, but it was still attacking the giant demon!

This is the first time he has encountered such a treacherous situation that he can't control marine life!
