Xia Yu hid in the aquatic plants, waiting for the opponent who suited him to appear and temper himself.

After a short time, a black fish more than a foot long with a head like a long knife appeared and slowly swam over.

"Second-level spirit beast, it's you. ”

Xia Yu's body rushed out like a sharp sword.

Xia Yu's appearance had already alarmed the black fish, and the black fish began to startle, but after seeing Xia Yu clearly, it was just a small fish in the body refining realm, and it rushed over in an instant, and the head like a long knife parted the water waves, stabbing Xia Yu directly.

Xia Yu dodged and dodged, and with a swing of the fish's tail, he slammed into the black fish's body, pulling the black fish out more than two meters away.

The body of the black fish rolled, the scales crumbled, and wisps of blood flowed out.

Xia Yu did not stop attacking, and instantly came to the side of the black fish again, and the fishtail was pulled out again, and the black fish was pumped away again.

Under Xia Yu's serial attacks, Heiyu didn't even have a chance to backhand, and it didn't take long for his eyes to roll and he couldn't breathe.

"It's too weak to achieve the purpose of my own training. ”

Xia Yu didn't even look at the dead black fish, and swam into the distance.

There are a lot of fish in the sea without regrets, just like the stars in the sky, and most of them are low-level spirit animals.

Xia Yu had just swam out a short distance when he saw a large yellow croaker more than a foot long, with a faint halo on his body.

"Second-level spirit beast. ”

Xia Yu, who was eager to fight, quickly rushed forward.

The big yellow croaker looked at Xia Yu who rushed towards him, and was stunned for a moment, his eyes were full of disdain, as if to say that Xiaobai, a first-class spirit beast, dared to challenge himself, isn't this the rhythm of looking for death.

As soon as Xia Yu swam in front of the big yellow croaker, he saw the tail of the big yellow croaker swing, breaking through the water and heading straight for Xia Yu.

Xia Yu's figure suddenly turned and rushed to the other side of the big yellow croaker, also swinging his tail, and slammed it on the big yellow croaker's body.

The big yellow croaker flew out more than five meters away in an instant, its scales flying wildly, and blood spurted out.

Xia Yu instantly swam in front of the big yellow croaker again, and once again whipped the big yellow croaker away.

Pump the large yellow croaker several times in a row.

The originally very beautiful scales on the big yellow croaker had fallen off, and it was extremely miserable, and suddenly a mouth opened, and a water sword shot out of the mouth. The speed of the water sword was extremely fast, and it hit Xia Yu's body in an instant.

Xia Yu felt that he was instantly pierced, and his body rolled and flew out.

When Xia Yu stabilized his body again, he saw that a big hole had been pierced in his abdomen, blood was flowing everywhere, and the scales did not know how much had been shattered, and he was weak.

The big yellow croaker saw that he had succeeded in one blow, and instantly swam in front of Xia Yu, and the fishtail was slapped down like a mountain.

Xia Yu also disregarded his injuries and collided with the big yellow croaker for his life.

The water was instantly dyed red, and the scales kept flying.

After a while, the big yellow croaker was still defeated, and its body slowly sank to the bottom, and it was already out of breath.

Xia Yu dragged his seriously injured body and slowly left.

"Hurry up, just enter and leave here, the smell of blood here is too strong, and it will soon attract a large number of spirit beasts, and the spirit beasts in the water are the most sensitive to the smell of blood. ”

Xia Yu cheered himself up while swimming.

Xia Yu swam back to his cave with difficulty, used his last strength to block the entrance of the cave with a stone, and then hurriedly cultivated to recover his injuries, this time the injuries were a bit serious.

Soon, Xia Yu was wrapped in a layer of spiritual mist, and the injuries on his body slowly healed.

I don't know how long it took for the spiritual mist around Xia Yu to slowly dissipate, and Xia Yu slowly opened his eyes.

"The spirit beasts in the water should not be underestimated, a second-level big yellow croaker will hurt itself, and there is still a lot of room for growth. ”

Xia Yu felt his body, and his strength increased a little more, and it was worth it for him to be injured.

Xia Yu began the battle to the death, facing all the second-level spirit beasts.

At the beginning, he was constantly injured, but later, he could easily defeat any second-level spirit beast.

Xia Yu looked at his body that was more than a foot long, the lines on his body were beautiful, and the scales were shining with a halo, and he laughed in his heart: "Now I want to challenge a third-level spirit beast, and if I don't want to defeat a third-level spirit beast, it is a victory to be able to retreat with my whole body." ”

With the attitude of giving it a try, Xia Yu hid in a patch of aquatic grass, waiting for the arrival of the third-level spirit beast.

Groups of small fish swam in front of Xia Yu, all of them were first-level spirit beasts, Xia Yu was completely unmoved, indifferent to these first-level spirit beasts.

There are also second-level spirit beasts that continue to appear, and they are not interested in these defeated Xia Yu.

It wasn't until half a day had passed that I saw a big herring more than two feet long slowly swimming over in the distance.

"Here it is, third-level spirit beast. ”

Xia Yu looked at the big herring that slowly swam over, and as he got closer and closer, the figure of the big herring became clearer and clearer.

There is a faint layer of blue light flashing on the body of the big herring, and the scales are smooth and crystal and arranged in an orderly manner, as if they are like armor.

Xia Yu waited for the big herring to come to him again, and quickly rushed out, and the tail of the fish swung on the big herring's body.

"Smack. ”

The big herring only retreated two feet slightly, not even a single scale fell off, but Xia Yu, who was attacking, was shocked back a few meters away by the force of the shock.

"It's not good, run. ”

Xia Yu knew that he was invincible, the gap was too big, so he turned around and left.

When the big herring saw that he had been attacked by a first-level spirit beast, he was immediately furious, let out a strange scream, and chased after him.

The speed of the big herring is very fast, and it chases the head and tail of the fish in an instant.

Xia Yu suddenly even had the heart to die, why did he provoke the third-level spirit beast well, this was looking for death by himself.

The big herring opened its mouth, revealing two rows of sharp teeth, and bit down on Xia Yu.

Xia Yu suddenly broke out in a cold sweat all over his body, and his body dodged to the side, narrowly avoiding it.

The big herring saw that the blow was useless, and another mouth and a water sword spewed out.

This water sword was hitting Xia Yu's body, and the scales on his body were suddenly shot down, and a large amount of blood was scattered in the water.

Xia Yu's body was suddenly planted in the aquatic plants at the bottom of the water.

The big herring swam into the aquatic plants to carefully look for Xia Yu's traces, but they only rummaged through the aquatic plants, but they couldn't find Xia Yu, and left helplessly after a while.

Xia Yu hid in his stone cave, looked at the departing big herring, breathed a deep sigh of relief, and lay on the ground softly.

Xia Yu's scales fell off at this time, and a deep scar went from the tail of the fish to the head of the fish, almost splitting Xia Yu in half.

Xia Yu began to use the exercises to absorb the aura to heal his injuries, and slowly the aura gathered over, which was much slower than usual, which showed how heavy Xia Yu's injuries were.

As the aura slowly wrapped Xia Yu, the cave became calm.

There are many vegetation on the bottom of the sea, there are more fish creatures, and countless battles are taking place all the time, in order to survive in order to become stronger, in order to stand at the top of the food chain, in order to be able to look down on the common people.

Big fish eat small fish and small fish eat dried shrimp, this is the eternal truth of nature, and it is also the rule of survival in the universe.
