The two of them raised their heads, and there was almost a rock wall above, stabilizing their bodies and not being moved by the current.

But once you move forward, the whole person has to dive into the water.

Fifth-order professionals, or in other words, occupations that have not yet reached the transcendent level, their bodies are still mortal, they can't leave the air, and they also need to eat to replenish their energy.

This is why places such as the ocean are taboo places for human professionals.

Many of the fierce beasts there are located thousands of meters below, and even if their bodies can withstand the huge pressure brought by the sea, they will be defeated if they fight below for too long and cannot breathe.

This is also the reason why, in the academy, in the spiritual spring, students are forbidden to poke their heads into the water.

After all, the spiritual power under the spiritual spring is mixed, which will disrupt the operation of the spiritual power of the entire body, and eventually be "drowned".

It's drowning, indeed.

Of course, it is also a mortal body, and now the strength of the fifth-order Du Hei and Zhang Hao is not low, if it is a situation of holding their breath, it is not much of a problem not to breathe air for more than a quarter of an hour.

But the problem is, no one knows if there will be any other dangers below.

Like the beast.

For example, the same vines as before.

If you get entangled in these things below, it will naturally be full of danger.

"How?"

Zhang Hao asked, "Shall I go down?"

"You're in the back?"

Du Hei shook his head: "There are guys who go down." ”

After finishing speaking, the spiritual power moved slightly.

A few seconds later, Du Hei and Zhang Hao felt something appear under their feet.

Zhang Hao was slightly stunned, and Du Hei said at this time: "Don't be surprised, the fourth-order summoning skill, the deep cold thorn fish." ”

"A street fighting skill, the first time I used it. ”

Du Hei's words were very casual.

It was a skill he had been learning for a long time, and he had never used it.

As for the reason, it's simple.

This skill summons beast is only suitable for fighting in the water, and can release cold currents, plus its own spiny fish appearance, it is extremely fast.

But if on the shore......

Except for two flutters, it's no different from salted fish.

Naturally, there is little opportunity to use it.

But now, if the next road is water, there is nothing better than this skill.

Du Hei grinned at this time: "Let it explore the path first." ”

After finishing speaking, the deep cold stinging fish below, the streamlined body burst out with extreme speed in the water.

Moment......

In the rippling waves, it has already shot out a distance of dozens of meters.

Dividing a wisp of spiritual power and attaching to the body of the deep cold thorn fish, Du Hei did not take control of its body, but only observed the surroundings and the front through its sight.

The speed of the deep chill stinging fish in the water is comparable to that of a cheetah on land, almost a second at a distance of tens of meters.

After about a minute, Du Hei was finally in good spirits.

"Huh?"

Ahead, he saw a glimmer of light.

With a sudden movement of his mind, the speed of the stinging fish slowed down a lot, and he gradually stopped in place.

"Seems to be something?"

After waiting quietly for a moment under the water, Du Hei clearly heard some sounds coming from the light through the deep cold thorn fish.

"Tick, tick. ”

"It seems to be the sound of water droplets?"

Du Hei was a little stunned.

Just as he was a little puzzled, suddenly, he saw a drop of green liquid slowly seeping down the bright position.

Although the seepage water is also liquid, it is as if oil and water are incompatible, and it is not fused.

Instead, he was alone, floating in the water.

"Hmm. What is this?"

Du Hei noticed the extraordinaryness of the green liquid, which reminded him of the spiritual liquid secreted by Wumao every week.

Seeing this drop of green liquid, slowly drifting towards this side along the water waves, Du Hei gave an order to the Deep Cold Thorn Fish at this time.

Bump into it!

He wondered what this green liquid was.

The Deep Cold Thorn Fish swam towards the green liquid, and in an instant, it came into contact with the green liquid.

The moment they made contact with each other, Du Hei felt that an inexplicable force instantly poured into his body.

"This is?!"

Du Hei was a little stunned.

He felt a huge and extremely powerful force, which instantly caused the entire body of the Deep Cold Thorn Fish to begin to collapse inch by inch, and then turned into spiritual power and dissipated.

......

Outside.

Du Hei's body trembled, and his face was a little shocked.

"What's wrong?" Zhang Hao saw that something was wrong with Du Hei and said a little nervously.

"Huh?" Du Hei came back to his senses at this time, and there was a bit of confusion in his eyes.

"What kind of power was that just now?!"

Duhei was a little distracted.

What he could be sure of was that the force did not seem to be aggressive.

Before the body of the Deep Cold Thorn Fish collapsed, he clearly felt that the aura of the Deep Cold Thorn Fish's body had skyrocketed in an instant.

It seems to have made a life leap, but in the end the evolution failed?

Confused for a moment, Du Hei's eyes suddenly lit up at this time.

"Like, a huge life force?"

He reacted.

The aura that erupted from the body of the Deep Cold Thorn Fish just now seemed to have a tendency to evolve from summoned creatures to complete lifeforms.

But in the end, because of the lack of foundation for its own existence, the body collapsed.

This explanation makes perfect sense.

After all, the Deep Cold Thorn Fish does not have a soul, and its body is only composed of a small amount of void spirit power, which cannot accommodate the infusion of life force at all.

And, most critically, ......

If this is the case, then it is clear why those strange poplar mizuki before evolved to that level.

An ordinary plant absorbs a huge amount of life force, and plants need life force to grow and evolve, and it is completely common sense to reach a higher level when the needs are satisfied.

However, Du Hei is not sure yet.

After all, the whole process of exploding just now was too fast, so fast that there was almost no time to react.

His feelings about that power were only for a second.

Looking back, looking at Zhang Hao, who was still confused, Du Hei said at this time: "Let's go down." ”

"There is no danger along the way, but this stretch of water is not a short journey. ”

"After a while, I summoned two deep cold thorn fish, and you and I, each pulling the fins above them, went straight over. ”

"There's something magical up there. ”

Du Hei's heart was throbbing at this time.

After saying his words to Zhang Hao, he directly began to summon.

A few seconds later, the two of them dragged the deep cold thorn fish, and in its rapid movement, it headed towards the depths of the waterway.

At the same time as the layers of waves rolled over, a moment later, the light reappeared.

It's just that this time, it's no longer seen through the sight of the summoned beast, but really relies on its own eyes.
