The white turtle still stayed, lying on Xia Yu's shoulder.

Whether it is Song Mengfei's unicorn or Li Zhuang's big bird, they are full of fear of this white turtle.

Especially Li Zhuang's big bird, after all, his bird feathers were plucked by this white turtle.

Xia Yu sang psychic songs to the white turtle many times, wanting to sign a contract with this white turtle, but it had no effect.

The white turtle often made a vomiting expression, which made Xia Yu angry.

At night, Li Zhuang and Song Mengfei practiced cross-legged and condensed their bones.

Both of them are already in the three-grade realm, and the key to the three-grade realm is to temper the bones.

There are a total of 206 bones in the human body, and if you refine 60 percent, you can advance to the fourth grade.

Of course, if all the bones are tempered, the physical fitness will be greatly improved.

If the meridians of the second grade are ultimately determined by speed.

The bones of Sanpin determine the hardness of the body.

Xia Yu is bored, his strength is already the peak of the second grade, and he has been holding it back these days, because he can be promoted to the third grade if he can't hold it, and Xia Yu doesn't want to be promoted to the third grade yet.

The last section of his last meridian has reached a bottleneck, and no matter how he practices, he can't practice it, and the difference is just the slightest chance.

The white turtle climbed down from Xia Yu's shoulder, and then wrote a line crookedly on the ground.

Xia Yu looked at it, no need to ask, he definitely couldn't understand it.

But he has a mobile phone, he took a picture, and then translated it through a special software - climb with me!

Climb with me? If you go with me, Xia Yu can still understand, what kind of turtle is crawling with me?

The white turtle rolled his eyes at Xia Yu, and then turned into a white light and disappeared into the distance.

Xia Yu hurriedly chased in this direction.

The speed of the white turtle is very fast, and it is almost a ray of light.

Xia Yu has already opened up nineteen meridians, and his speed has naturally reached the extreme, it can be said that it is impossible for anyone among the second-grade martial artists to be faster than Xia Yu, and even most third-grade martial artists are not comparable to him.

In the end, the white turtle stopped at a lake, looked at Xia Yu who was following closely behind him, and showed a good expression of your kid.

The white turtle scribbled a line on the ground and sand - the middle finger of his right hand was stretched out.

Although he was confused and didn't understand, Xia Yu still copied it.

He put his finger to the white turtle's mouth, and then the white turtle looked at it, opened its mouth wide, and bit it down directly.

A heart-piercing pain made Xia Yu grin his teeth, and then he felt that there seemed to be some magical substance in his blood.

With a bang, Xia Yu felt that the last meridian was hit open by a strange force at the last moment.

In an instant, all of Xia Yu's twenty meridians were all connected, and then hooked together.

The spiritual power did not urge, but spontaneously started from the source of the Dao, and then flowed among the twenty meridians, as if there was an invisible engine that was constantly accelerating the spiritual power in the meridians.

Almost instantly, the layer of barrier between the second and third grades that Xia Yu had so hard suppressed was defeated, and in an instant, Xia Yu's strength entered the third grade from the peak of the second grade.

Xia Yu Dao source has the power left by the spirit peach, and at this moment, all the power accumulated by the spirit peach is activated, and it also enters Xia Yu's meridians, and the spiritual power is refining the bones at an almost crazy speed.

One, two, three...... Thirty-six bones were soon quenched.

Xia Yu didn't know how fast others were, but the speed at which he refined his bones was so fast.

It wasn't until the thirty-seventh bone began that the speed at which the spiritual power was refining the bones slowed down.

It is said that Song Mengfei and Li Zhuang have only refined about twenty bones so far.

Xia Yu's body emitted a blazing light, and a round of the sun appeared above Xia Yu's head, shining in all directions.

This time, the Jiuyang Burning Heaven Skill did not let Xia Yu run naked, the blazing light was fanatical to the outside, but it was very gentle to Xia Yu, and invisibly, Xia Yu's control of this set of exercises was greatly improved.

The second round of scorching sun has already taken shape, only the size of a fist, juxtaposed with the first round of scorching sun, the light is not as hot as the first round, but more restrained and warm.

After a long while, Xia Yu exhaled a turbid breath and slowly converged his breath.

At this moment, he felt that his spiritual power had more than doubled.

The strength of the flesh shell on the body has also doubled on average.

The 36 bones were all concentrated in the left arm, which caused the hardness of the area to more than triple.

Not far away, the white turtle looked at Xia Yu, and nodded lightly with his little head, which means that you are not bad, and it is not in vain that Benlong will help you.

"That's not right, I've opened all twenty meridians now, and I've advanced to the third grade, but what about the miracle that Dean Tang said, it's not promising. Xia Yu suddenly thought of something.

The opening of the twentieth meridian increased Xia Yu's speed by a loss, and there was no expected quantitative change, nor did there appear the miracle that Dean Tang said.

The white turtle seemed to understand Xia Yu's doubts, and then he scratched the ground with his paws, and quickly wrote a line of crooked words.

Xia Yu glanced at it, naturally he still didn't know it.

I used my mobile phone to Baidu to express the content of the handwriting on the ground - full operation!

Full swing?

What is running at full strength, is it spiritual power?

Thinking of this, Xia Yu began to urge Dao Yuan to go all out to transfer spiritual power.

Since the twenty meridians were opened, Xia Yu's Dao source had automatically urged the rapid flow of spiritual power, and the flow speed of this spiritual power was already very fast, but this passive flow was naturally far less than the active one.

Xia Yu began to take the initiative to urge the flow of spiritual power.

He sat cross-legged on the ground, and with the rapid flow of spiritual power, streaks of light appeared on his body.

The light was white at first, but only the brightness of a candle.

As Xia Yu continued to urge his spiritual power, this light gradually turned golden, dyeing Xia Yu's entire body golden.

As Xia Yu's speed of urging spiritual power became faster and faster, almost ten times the speed of passive flow, a hazy shadow appeared behind Xia Yu.

This shadow is very faint and faint, if you don't look carefully, you can't see it clearly, but it is indeed very powerful.

But I don't know what to start, and a thick black cloud began to appear above Xia Yu's head.

The area of this black cloud is not large, but it is only more than twenty zhang in radius, but it has an oppressive and terrifying aura.

It was as if there was a huge beast hidden in this thundercloud, which could pounce down at any moment and tear the people below the thundercloud apart.

Xia Yu didn't know any of this.

He was just constantly urging the flow of spiritual power, and it was a little difficult at first, but then he couldn't stop at all.

When the speed reached twenty times, the shadow gradually became clear.

It seemed to be a burly figure, dressed in black animal skins at the waist and abdomen, with lush hair on his head and especially strong thigh muscles.

As the figure became clearer, the thunderclouds on Xia Yu's head became thicker and thicker, and a trace of electric arc haunted the thunderclouds.

The white turtle lay on the ground, looked at Xia Yu not far away, and then looked at the thunderclouds overhead, and became more and more interested.

Xia Yu continued to urge the spiritual power, and when it reached thirty times the speed of the passive state, some kind of balance seemed to be broken.

The shadow behind Xia Yu opened his eyes suddenly, and a vast aura flowed out of his eyes, as if he had experienced eternal years.

At the same time, the thunderclouds in the sky also brewed a thunderbolt, blasting towards the figure behind Xia Yu.

The figure seemed to sense the unspeakable crisis, and he opened his mouth and made a roaring motion.

The thunder light seemed to be pulled by some kind of force, and it turned a corner directly in mid-air, entered the mouth of the void, and disappeared.

The figure devoured the thunder and lightning!

As the thunder and lightning devoured, the thunderclouds also began to dissipate, and it seemed that he only had the power of one blow, and after the thunder and lightning was calm.

And at this moment, tens of thousands of kilometers away from Xia Yu, in a gray temple, there was a statue that opened its eyes violently.

Guarding the temple is an old Taoist priest with a crane-haired and childish face, with a strong and restrained breath, who has been meditating at the door of the main hall, looking like a pet is not shocked.

The moment the idol's eyes opened, he seemed to feel something, looking at the idol with his eyes open.

The old Taoist priest was taken aback, stood up suddenly, and the appearance of the fairy wind Dao bone just now was thrown directly out of the clouds.

He rubbed his eyes, and made sure that one of the gods had really opened his eyes.

"Is this an ancient god coming to earth? Let me see which ancient god it is, this statue is an ancient god - Kuafu ......."

The shock in the eyes of the old Taoist priest could not dissipate for a long time.

Among the ancient gods, Kuafu, who is famous for his speed, is about to reappear between heaven and earth?

I don't know which young talent broke the bottleneck in just the second grade and opened up all twenty meridians.

No, the human body has innate shackles, and it is impossible for ordinary people to open up all the meridians when they are in the second grade, could it be that the descendants with the bloodline of the ancient gods have reappeared?

......

"Xia Yu, what happened? I saw a bright light and thunder. ”

Song Mengfei rode a unicorn and rushed over from a distance.

Li Zhuang rode his bird behind.

Originally, Li Zhuang was supposed to be faster, but his bird had lingering fears about the white turtle, so naturally he would not fly in this direction honestly.

"I don't know. Xia Yu looked at the sky and replied confusedly.

As soon as he took the initiative to urge the spiritual power, the spiritual power turned out of control and went out of control.

The so-called bright light is not clear to him.

The so-called thunder is even more unclear to him.

It's just that the sound of thunder seems to be faintly heard.

"Is there any chance to tell the brothers?" Li Zhuang didn't believe it.

It was bright and thundering just now, and he could see it twenty miles away, otherwise he wouldn't have found it directly.

With such a big movement, can Xia Yu not know?

"I really don't know, the turtle has always been here, why don't you ask it?"

Xia Yu pointed at the white turtle.

Li Zhuang immediately shut up.

He still had a lingering fear of the white tortoise.

Such powerful birds are bullied so miserably.

"You guys are here just in time, I just wanted to ask, you are all refining bones, how is the efficiency of refining bones?" Xia Yu looked at Song Mengfei and Li Zhuang and asked.

"My speed is okay, I can temper one piece in about four hours, because I can't devote all my time to cultivation, so I can temper one piece almost every day, and now I can temper twenty-five bones. ”

Concubine Song Meng thought about it and said to Xia Yu with a little ostentatiousness.

"My speed is slower, I can temper one piece in almost six hours, and now I have tempered twenty bones, in fact, my speed is already very good, I have checked on the Internet, and it is generally ten hours to temper one. ”

Li Zhuang defended his speed, and he looked at Xia Yu: "Why are you asking this, have you advanced to the third grade?"

Li Zhuang and Song Mengfei carefully observed Xia Yu and found that Xia Yu's aura had indeed changed.

It turned out that they couldn't determine Xia Yu's strength through his breath, so they could only guess.

It's even more uncertain now, but Xia Yu's current aura is indeed more mysterious than before.

Since it is stronger than the original, it should be a three-product undoubtedly.

"Yes, I didn't hold back just now, and I was directly promoted to the third grade. Xia Yu opened his mouth and said, his expression was a little full of regret.

Li Zhuang suddenly looked loveless.

Others have to work hard to advance to the third grade, but Xia Yu didn't hold back and advanced.

Sure enough, people have to die more than people, and goods have to be thrown away.

"Don't worry, according to your speed, if you cultivate well, it won't take you half a month to reach my level. Li Zhuang patted Xia Yu on the shoulder to express comfort.

"Ahem, I'm sorry, I'm now past you, and I've already refined a full thirty-six bones. Xia Yu patted Li Zhuang on the shoulder and came to a reverse comfort.

"Didn't you just advance, how did you already refine thirty-six bones?" Li Zhuang looked at Xia Yu dumbfounded.

"I don't know, maybe it's because I've been holding back in the second-grade realm for too long, so I refined thirty-six bones as soon as I was promoted. Xia Yu found an explanation for himself.

"Then how many hours can you refine a bone?" Song Mengfei asked.

"Well, I don't know, I haven't tried it, but I guess it won't take more than four hours. Xia Yu hesitated for a moment and said.

In fact, Xia Yu had already felt it just now, in a passive state, Xia Yu should be able to temper a bone in about an hour.

This is still a passive state, if it is an active state, he has not tried it, it will be terrifying to think about.

But he couldn't tell the truth, because it was easy to associate with A-level qualifications, and he didn't want to be sliced in a daze.

Four hours to temper a bone, this speed should be in the category of B-level qualifications.

Well, it should be a very good B grade.

Xia Yu's phone rang, and he called in the middle of the night, Xia Yu was very impatient, but after taking a look, he couldn't help answering.

The call was actually from Li Zhen, at this point, is there anything important?
