Cao Yu, who was almost completely immersed in himself, didn't know that those Tianjiao were forced to turn pale one by one, as if he had just climbed off a woman's belly.

At this moment, Cao Yu was still excitedly compressing his true qi, and he found that the more his true qi was compressed, the higher the efficiency and the faster the speed would be!

When Cao Yu's true qi was constantly compressed, the color quietly began to change again, this time becoming a faint silver light.

The Heaven Stepping Double has already been perfected during this period, and he plans to start the cultivation of the third layer.

Thinking of it is to follow the requirements of the exercises, and the true qi is injected into several obscure acupuncture points.

"Boom!"

When Cao Yu injected his true qi according to the mantra of stepping on the sky, and after running for a week, his body suddenly doubled!

Directly double the original triple speed of sound!

Six times the speed of sound!!

Even if Cao Yuke tore through Wu Zong's body, he felt a faint pain, and the speed was too fast! The effects of friction and air pressure in the air were also increasing exponentially.

Qi Zhan, who was still a few kilometers away from Cao Yu, was running wildly, and suddenly felt the speed of the figure behind him suddenly increase.

Looking back, there is no doubt that it is Cao Yu.

"Haha! to my liking!Let's see if my secret method can not be surpassed by you!" Qi Zhan's face was full of excitement.

He will not have jealousy and hatred for beings stronger than him, that is his whetstone, and it is too late for him to be happy.

After saying that, Qi Zhan slapped his chest fiercely, and the essence blood sprayed on a pattern that he had cast out of thin air with his hand trick, and suddenly the golden light flashed, and then it disappeared into Qi Zhan's brain.

"Tianxingbu!"

Qi Zhan drank heavily, and then his body accelerated suddenly, and his speed reached six times the speed of sound compared to before.

"Hahaha! Come on!" Qi Zhan shouted frantically as he ran, like a madman.

In this sonic boom one after another, Elder Mo at the front was alarmed!

"Not bad, not bad! Qi Zhan, this kid is crazy, but it's expected! Who is behind it?" Elder Mo stroked his mustache and smiled.

Feeling that the two figures were getting closer and closer, he was also slowly accelerating, as the presiding elder, his strength was naturally strong, and he was the most powerful one selected this time.

The strength has reached the stage of the Martial Queen, and the Martial Emperor is eightfold!!

If the students who were tried were compared, then he would not have the face to mix in the Tianfeng Academy in the future.

Cao Yu felt some faint pain in his body and didn't dare to increase the infusion of true qi, but the true qi in his body was still compressing with terrifying soul power.

Although the consumption of True Qi was reduced after compression, he couldn't withstand the consumption for a long time, so he also swallowed a few Yuan Qi Pills halfway, which were pills that could only be used by the Martial Emperor's powerhouses.

The reason why only the Martial Emperor is strong can use it is because the Yuan Qi Pill contains is too terrifying, and the ordinary Martial Sect Realm can't bear it at all.

But Cao Yu's monster is an exception, the vitality of the Yuan Qi Pill is just like the true qi in his current veins for Cao Yu, naturally it has no effect on him, and he still wishes for a richer true qi.

Time passed quickly, and in the blink of an eye, Cao Yu and they had already walked two-thirds of the way, and the true qi in Cao Yu's body was shrunk into an extremely thin strand by him, and it ran in the veins for 360 weeks.

The color of that true qi has completely changed to silver

"Boom!"

Again, there was a sound like a breakthrough.

When Cao Yu injected the silver true qi into those acupuncture points again.

"Huh"

The body continues to speed up again on the basis of the six-fold tone!

Seven times the speed of sound!

Eight times the speed of sound!

Nine times the speed of sound!

Qi Zhan, who was in front of Cao Yu, was suddenly dumbfounded and burst into a foul mouth.

"Nima!

Then he flew through Qi Zhan's round pupils, his speed was like a child's running, and Cao Yu was the sprint champion.

"Haha! you are qualified to be my friend of Qi Zhan, I am optimistic about you, and I will surpass the old man in front of me."

Although he was a little unwilling, Qi Zhan was still excited.

"Huh?"

Elder Mo, who was leading the way in front, suddenly felt a breath and galloped at a speed that was not inferior to his.

You must know that he is flying in the sky, and he doesn't have to dodge anything at all, while Cao Yu needs to be distracted and always pay attention to avoiding those obstacles that block him.

"Nice boy, but if you want to surpass the old man, you are still a little tender"

After speaking, Elder Mo's vitality sped up, and his body immediately accelerated.

You must know that when you reach the realm of the Martial Emperor, the true qi has been transformed into the vitality of the vitality, and the energy contained in the vitality is not at all comparable to the true qi, and the vitality is also the greatest reliance that the strong of the Martial Emperor can fly above the sky.

With the rapid operation of Elder Mo's vitality, his speed was also increasing towards nine times the speed of sound, and the speed of the strongest peak powerhouse in the Martial Emperor Realm could only reach ten times the speed of sound.

It's not that they can't accelerate anymore, it's that the strength of the body reaches its limit, and speeding up any more will cause damage to the foundation.

Unless it is chased and killed, to the point of desperation, the average strong person will not easily exert such a fast speed.

Of course, physical martial arts are also a limiting factor, and some strong people have no hope of breaking through ten times the speed of sound at all.

Because Cao Yu's true qi broke through to silver, his speed increased sharply, and the limit of his body's bearing was almost reached, so he controlled the amount of true qi injected, and he didn't dare to go any faster, for fear that his body would collapse.

His goal was still to concentrate on compressing his true qi, which also benefited from his soul power and strong body, otherwise he would be an ordinary ordinary cultivator.

Even if the true qi is compressed to bronze, it will explode directly and die.

In the Xuantian Continent, there are almost no demonic teenagers like Oak Cao Yu, the body exceeds the cultivation of two realms, and the soul is even more terrifying, directly exceeding the cultivation of three realms.

Moreover, it is three major realms, not small realms, normal cultivators, especially the power of the soul, can keep up with their own cultivation has already burned high incense, let alone surpass the cultivation of a great realm.

Cao Yu's kind of coincidence has no precedent in the past, and the history of madmen refining bodies abounds.

The strength of the soul is the foundation of Cao Yu.

In some ancient hermit families, there is such a legend.

If a cultivator is able to break through the cultivation with the three transformations of supreme qi when the Martial Spirit Realm begins to break through each great realm, he will become the first person in the same realm of the Tianxuan Continent and even the Ten Thousand Realms.

Previously, many people who knew this legend were thinking hard about what the so-called Three Turns Supreme Qi was.

Some people say that it is the most mysterious and wonderful aura of heaven and earth.

Some people say that it is refined by divine skill, and this divine skill is born from the creation of heaven and earth.

。。。。

All kinds of different legends have been tried, think about how many years and millions of years of history have been passed down from generation to generation since the formation of the Xuantian Continent.

I don't know how many old monster-like characters use their own juniors to try the legendary supreme qi breakthrough.

However, the end result was a failure, and it was once thought to be a false legend.

But the old antiques from that old family came out to clarify.

The legend is true, and his ancestors have indeed reached it, but the specific cultivation method has not been told.

Because no one has been able to do it for countless years, this legend has been hidden.

After all, there are very few people with such a special experience as Cao Yu, and occasionally there are people with strong souls who pay attention to the cultivation of martial arts and exercises, and will not distract their energy anymore, because the powerful techniques have made them become masters, and naturally they will not pursue the tempering of the body.

And by the time he realized that he wanted to improve the strengthening of his body, it was already time to break through the martial spirit realm.

Originally, Mo Kedi thought that Cao Yu was using some secret method to slow down after winning the first place, but he didn't want this kid to maintain nine times the speed of sound.

In this way, Mo Kedi will be bitter, although he is a strong person in the Martial Emperor Realm, but he can't stand it if he continues to consume such a large amount of true qi.

Cao Yu in the rear was like a stunned man, tireless, and kept maintaining nine times the speed of sound.

At this moment, although Cao Yu's physical pain had aggravated a lot, he was immersed in the comfort brought by compressing the true qi, and he was willing to give up the compression, and once again used his terrifying soul power to compress the true qi in the meridians and the sea of dantian qi.

After turning into Silver True Qi, the difficulty of compression increases dramatically, because the True Qi is compressed to a certain extent before continuing, and the required soul power and body strength are multiplied.

If we weren't running at nine times the speed of sound, the compression would be much easier and the body would be much less stressed.

However, he will definitely not be willing to let Cao Yu give up, as long as his body is not at the limit, he will continue to compress.

In the process of compression, Cao Yu himself also had some senses, he should have touched a very wonderful realm, and he believed that when the true qi was compressed to the limit by him, it would bring him a surprise.

Time passed, and another hour passed in the blink of an eye, and the true qi color in Cao Yu's body was compressed by him after running at a super high speed for 480 Zhou Tian and powerful soul power.

The color of true qi began to turn into a faint gold, and this change made Cao Yu almost jump.

"It can really be compressed!"

Holding back the joy in his heart, Cao Yu ran while frantically compressing his true qi.

Elder Mo, who was less than two kilometers in front of Cao Yu, was already slightly red at this moment.

"Won't this little bastard get tired?" Mo Kedi scolded in his heart.

It really can't erase that face if he gives up, so now Mo Kedi has to grit his teeth and insist.

After another hour, Cao Yu had already turned his True Qi for 700 Heavens, and at this moment, the faint golden color of his True Qi was several times richer than before.

Finally after 720 weeks of operation!

"Boom!"

It's still the same break-through sound, only this time it's much louder.

The true qi in Cao Yu's body was all transformed into pure gold!

After the golden true qi was injected, the speed suddenly accelerated!

Ten times, eleven times, twelve times the speed of sound

"Ahh

The body can only withstand nine times the speed of sound, and Cao Yu immediately reduced the input of true qi by half, and the speed is still ten times the speed of sound.

In the end, just by inputting two percent true qi, you can reach nine times the speed of sound.

So at this moment, Cao Yu didn't have to worry about the consumption of true qi by stepping on the sky, but worried about the problem that his body couldn't bear it.

The original desire was compressed again, but neither the body nor the true qi seemed to be able to bear it at all, and the compression to this extent seemed to have reached the limit of this realm.

At this moment, Cao Yu's heart was also patient.

When he opened his eyes and looked high in the air ahead, he saw that Elder Mo Kedi was pouring pills into his mouth.

Seeing this, Cao Yu endured the pain in his body and accelerated to ten times the speed of sound towards Elder Mo.

Elder Mo, who was devouring the pill wildly, felt a tightness in his heart, and that little bastard was still speeding up!

He wanted to cry without tears, but when he felt his true strength, he smiled miserably.

"That's it, there's nothing to be ashamed of, it's just a matter of joy."

Elder Mo slowed down and walked forward at a normal speed.

No, Yu Cao Yu's voice came from below.

"Elder Mo, what's wrong with you? Are you injured? Why do you have to swallow so many pills?"

Hearing this, Mo Kedi almost fell from a high altitude, and said secretly: "It's not you little bastard yet"

"Oh, it's okay, the old man's old illness has recurred, and he needs to take some healing pills every once in a while, it's okay!" Mo Kedi said indifferently.

"That's it, Elder Mo will speed up a little bit when you're rested!

“。。。。 ”

Elder Mo was in an extremely embarrassed mood at the moment, but he couldn't say anything, so he could only reply far-fetchedly: "Wait for the old man to rest for a while, and then speed up a little faster! The people in the rear haven't come so fast, you have already won the first place, you don't have to be so fast."

"What Elder Mo said is reasonable!"

After hearing this, Mo Kedi breathed a sigh of relief in his heart, if this little bastard insisted on hurrying, he couldn't refuse, it would be a shame.

His tongue, which had tired him before, was about to stick out, and now his face was pale, and he used the old wound as an excuse.

If it continues, the old life will be cut in half by this little bastard.

He intends to be cheeky and slowly reach the finish line due to his injury.

When he thought about it, if the old guys in the academy knew about it, he really didn't have a face.

When the presiding officer is forced to do this by the trialist, he is unique!
