Bang!

The surrounding river water seemed to explode suddenly, countless bubbles rose one after another, and the mud and stones at the bottom of the river were swept up, forming a huge whirlpool, like an underwater tornado.

Whoa, whoa!

The momentum is amazing!

And Li Yi, who was in the center of the whirlpool, showed a hint of surprise.

The magic power of the wind has finally broken through the realm of Xiaocheng!

Carrying a boulder on his back and facing the turbulent river, Li Yi urged the wind to be supernatural.

He started running!

At the bottom of the Shentian River, going upstream, it is very difficult for ordinary people to even take a step forward, if they are carrying a boulder, it is not bad if they are not flattened, it is impossible to move a step, but Li Yi is actually running!

Knock, knock, knock, knock!

There was a loud shaking sound on the riverbed, like a giant beast passing by.

If he returns to the land, without the resistance of the river, and then puts down the boulder, Li Yi's speed will be even faster to an extremely terrifying point.

This is the power of the Wind Divine Power, although it is very hard to cultivate, but every point of hard work, no point of harvest, the reward is also very rich.

Li Yi ran more and more energetically, feeling a rare freedom, these days at the bottom of the river is difficult, at this moment he can finally run wantonly, like a wild horse.

Unconsciously, he ran to the upper reaches of the Shentian River, that is, near the section of the Netherworld Forest, and suddenly, a purple light appeared not far away.

"Huh?" Li Yi looked curious, "What's that?"

There was no light at the bottom of the Shentian River, and the light was extremely dim, but the light was quite dazzling.

Approaching the past, Li Yi found that the light came from a huge cave, and when he stepped into the cave, he saw two skeletons, sitting in a corner, with their left and right hands on each other's chests respectively, their sternums had been shattered, and they seemed to have died together, and their bodies were covered with a thick layer of mud and sand, and they should have been dead for many years.

The other hand was holding something together.

It was a dark purple object that emitted a harsh glow, and the surface was uneven, looking like a glowing stone.

Li Yi was taken aback, and said secretly: "Why did these two people die here? Could it be that they died together to fight for this stone? What kind of stone, is it worth letting them not even want their lives?"

I was about to reach over and pick it up to take a look, when suddenly a loud roar came from the depths of the cave.

Under the impetus of the sound wave, a huge wave surged, pushing Li Yi back a few steps, stabilizing his body, and showing a hint of surprise on his face.

"This cave is actually a lair of demon beasts?" Li Yi frowned, "What kind of demon beast is it that is so powerful just by roaring?"

Secretly raising his vigilance, staring ahead, after a while, he felt that the mountains were shaking, and a huge figure gradually emerged.

The demon beast was several feet tall, and its appearance was quite similar to that of a turtle, but it was not a turtle, it opened its mouth, it was full of sharp fangs, all four legs had sharp claws, and its eyes were full of fierce light.

"This is ......" Li Yi was slightly startled, "Xuan Turtle?"

He had seen the introduction of this monster beast in a book, and its biggest feature was its long lifespan, and it was rarely found, and the other characteristic was that it had a strong defense.

The tortoise shell is very hard and heavy, and it is the best material for refining defensive magic weapons, and it has always been priceless.

Although it is not among the four realms, its strength cannot be underestimated, especially at the bottom of the river, not on the shore, and Li Yi has a great disadvantage in terms of time and place.

What made Li Yi feel even more strange was that under the skin of the turtle, there was a faint purple light flowing, the same as the light of the strange stone in the skeleton's hand.

"Could it be that it has absorbed the power of this stone?" Li Yi guessed in his heart.

Suddenly, the Xuan Turtle roared and rushed towards Li Yi, with a momentum like a rainbow.

"It's so fast!" Li Yi's heart jumped, and he was very surprised.

It stands to reason that the speed of the turtle is very slow, not to mention that the size of this turtle is so huge, Li Yi thought that it must be extremely slow to act, who knew that it was a rabbit, and after a while, he ran to him, raised his giant claws, and slapped Li Yi fiercely.

Boom.

Li Yi was caught off guard and hurriedly dodged, looking a little embarrassed.

"It seems that it really has something to do with that stone, otherwise this turtle wouldn't have such a fast speed!" Li Yi said secretly, "It can make the turtle mutate, what is that stone?"

The turtle struck again, and its speed became even faster.

Li Yi was still carrying the boulder on his back, urging the wind magic power with all his might, the water was surging, and his body was in a vertical shape, avoiding the attack of the turtle.

Xuan Turtle couldn't succeed in three or four attacks, so he roared angrily and began to launch a more violent offensive, chasing and beating Li Yi hard, claw after claw, chain attack, and occasionally bite with fangs, tail sweeping, and in an instant, dozens of attacks.

But although its offensive is fierce, Li Yi's speed is too fast, even if he is carrying a boulder on his back and is under unfamiliar water, once he urges the wind magic power with all his strength, the speed is doubled, and it is not something that the Xuan Turtle can touch.

While dodging, Li Yi found a gap and flashed onto the back of the turtle.

The turtle rushed violently, trying to throw Li Yi down, but in vain, after knowing the strength of the opponent, he couldn't help but be a little discouraged, and with a swish, he suddenly retracted his head and feet into the depths of the turtle shell.

Li Yi was stunned, so he had to use his mana and slam his fist into the turtle shell.

Bang!

A powerful anti-shock force almost shook Li Yi away, and the boulder almost got out of his hand, he had a special physique, and his mana was extremely strong, this punch could be said to be indestructible, but the turtle shell was much harder than he imagined, and a punch blasted out, not only did not leave a mark, but shocked himself.

"What a hard turtle shell!" Li Yi secretly exclaimed.

But he didn't give up, and threw more than a dozen punches in a row, one punch heavier than the other, and each punch hit the same place.

Bang, bang, bang, bang!

The powerful fist power still couldn't break through the defense of the Xuan Turtle Shell, but every punch made Li Yi bear a huge force of shock, which shook his qi and blood, and his internal breath began to be disordered.

"This turtle shell is so hard, no wonder the turtle can live for so long, this is probably one of the reasons, the defense is really strong!" Li Yi felt a little helpless.

Suddenly, his mind moved, and he sacrificed the nameless sword.

"This sword is made of strange materials, extremely sharp, I don't know if it can break the turtle shell?" Li Yi was not too sure, but he had to give it a try, if it didn't work, then he would have no way to take this turtle.

Cast the "Sword Chopping Technique", a heavy and fierce sword, and slashed fiercely on the turtle shell.

Click!

The incomparably hard turtle shell was cut out of a gap!

Li Yi was pleasantly surprised, the power of the nameless sword with the "Sword Chopping Technique" exceeded his expectations, and he couldn't even resist the turtle shell, if it was slashed on a person, I don't know what the effect would be.

He aimed his nameless sword at the crack and stabbed it hard, killing the turtle.

Li Yi also used the demon refining technique to refine the essence blood of the Xuan Turtle.

The Xuan Turtle has a long lifespan, and the vitality in the essence and blood is extremely mellow, like drinking elixir, turning into a stream of life essence, which is integrated into Li Yi's flesh and blood, greatly enhancing his qi and blood.

The power of supernatural powers is not only related to the realm, but also related to qi and blood, and the stronger the qi and blood, the stronger the power of supernatural powers.

At the same time, after the qi and blood were strong, Li Yi's physique also became more refined, and the meridian dantian expanded again, which could accommodate more mana, which made him far superior to others in the same realm.

A few hours passed, Li Yi had finished refining all the Xuan Turtle essence blood, and his whole body exuded a solemn aura like a mountain, and his blood had been condensed to a very high level, very viscous, like gelatin, slowly circulating in his body.

Li Yi was satisfied, threw down the boulder, and wasted a long day of effort before peeling off the turtle shell and carrying it into a storage bag.

The tortoise shell was extremely heavy, much heavier than the boulder.

At this moment, his face suddenly changed.

He had been paying attention to the enhancement of qi and blood, and ignored the mana, and at this time, he suddenly noticed that the mana in the dantian had changed strangely compared to before.

Mana is formless and substantial, invisible and intangible, colorless, and weightless, but at this moment, the mana in his body clearly has a faint purple color, and it looks a little heavy.

"This ...... It's ......" he was amazed in his heart, almost in disbelief.

This is a sign that the mana has undergone a metamorphosis and is about to turn into true qi.

True Qi has a body and color, and has a variety of different attributes.

But if you want to transform mana into true qi, there is one of the most important conditions, that is, you must refine a heaven and earth spiritual object and integrate it into mana, so that you can have a chance to condense true qi.

Different heaven and earth spiritual objects condensed into different true qi, such as Li Tiancheng's heavy water true qi, which was condensed by a drop of ancient heavy water.

"Could it be that this stone is actually a kind of heaven and earth spiritual object?" Li Yi fell on the two skeletons, his heart was pounding, the turtle absorbed the power of the strange stone, and he refined the turtle essence blood, and the mana was mutated, and the connection between them could not be more obvious.

Stepping into the Quadruple Passage and condensing True Qi has been his dream for many years, and the reason why Li Tiancheng is crushing him to the death is because he has refined a heavy water True Qi.

It's just that the heaven and earth spiritual objects are so easy to obtain, so although Li Yi is very eager, he doesn't have much hope.

Hope was right in front of him at the moment, but it felt very unreal for him, like a dream.

Carefully remove the strange rocks and take a closer look.

After I started it, I felt heavy and a cold tingling sensation.

"With such a small stone, let them fight with their lives and finally die in this demon beast's lair, I thought it was strange," Li Yi said secretly, "But if it is a heaven and earth spirit object, then everything can be explained, but I don't know what kind of heaven and earth spirit thing it is?"

He tried to slash hard at the stone with his nameless sword, but was unscathed, much to his surprise.

The nameless sword can even cut through the shell of the turtle, but it can't help this small stone?

"It seems that this stone is indeed not simple, and when I get back, I will find out what it is. Li Yi suppressed the excitement in his heart and put the strange stone and the nameless sword into the storage bag.

Urging the wind supernatural power, his body was longitudinal, like an arrow from the string, rushed out of the water, and with a bang, it fell heavily on the riverbank, smashing two deep footprints on the ground.
