Xu Ning naturally knew the rules of the library, so he also came prepared.

Xu Ning took out the original Mending Heaven Sutra that he had copied from his arms, handed it to the old man, and said, "Third Grandfather, what do you think of this exercise?" ”

The old man took the Heavenly Scripture from Xu Ning's hand, opened it and flipped through it.

Seeing the introduction on the homepage of the Mending Heaven Sutra, the old man's expression suddenly became solemn.

"Where did you get this exercise? Is it really as amazing as it says it is? The old man asked.

"This kid got it by accident!" Xu Ning chuckled and replied, "Cultivating according to the method mentioned above, my body has fully recovered!" ”

Hearing this, a look of surprise flashed in the old man's eyes.

Although the old man has been guarding the library building, as a senior of the royal family, he still knows very well about the situation of the juniors of the Wang family.

Wang Ping was a genius when he was young, but unfortunately he was assassinated, and his cultivation was abolished and he was reduced to a wasted person.

Immediately, the old man grabbed Xu Ning's palm, and a wisp of internal qi probed into Xu Ning's body, and sure enough, he found that Xu Ning's meridians and dantian had recovered as before.

Not only that, but his meridians and dantian were also several times larger than ordinary people.

Retracting his internal qi, the old man nodded slightly, "If that's the case, this Heavenly Meridian really has the effect of changing one's life against the sky!" ”

After all, Wang Ping is young, has little contact with the outside world, and does not know much.

But the old man knows very well the preciousness of this miracle book of mending the heavens.

In this world, there is no kind of elixir or treasure that can treat the meridians and dantian.

Once in the battle, the meridians and dantian are in their hands, and the light will be cultivated to fall, and the heavy will become a waste.

In this world, there are countless people whose meridians or dantian have been damaged, and if they learn about the existence of the Heavenly Meridian, his Wang family will definitely become the target of public criticism.

Then, the old friend said to Xu Ning again: "You can go to the third floor to choose an exercise!" However, this Heavenly Sutra is extremely precious, and you must not leak a trace of information! ”

"I know, Third Grandpa, I'll keep it a secret!" Xu Ning nodded in response.

"Well, okay, let's go up!"

After speaking, the old man made way for Xu Ning, Xu Ning saluted the old man, and walked up to the third floor.

The room on the third floor was small and dark, with only one bookcase, and on top of the bookcase were neatly placed more than a dozen boxes, and those ground-level exercises were placed in these boxes.

And Xu Ning's goal is also very clear, that is, in the library building, the only broken heaven-level exercises.

This heaven-level exercise is called the Nine Heavens Pure Yang Gong, with a total of nine layers, cultivated to the extreme, you can incarnate into a pure yang body, condense the power of the nine yangs, burn the sky and boil the sea, and have the power to destroy the world.

However, because the exercises are incomplete, there are only the first three layers, and at most they can only condense the power of the three yangs, and the power is only equivalent to the ground-level lower-grade exercises.

After getting the Nine Heavens Pure Yang Gong, Xu Ning took out a pen and paper and copied a copy of it.

And the original exercises are still put back in the box of the bookcase.

Then, Xu Ning went down to the third floor, said hello to the old man, and hurriedly left the library building and returned to his small courtyard.

Xu Ning came to the study, sat at the desk, and carefully studied this Nine Heavens Pure Yang Gong.

Reincarnated in this world for a period of time, Xu Ning had already figured out the cultivation system of this world somewhat, and coupled with his rich knowledge reserves, it didn't seem difficult to complete this Nine Heavens Pure Yang Gong.

Xu Ning had been studying the Nine Heavens Pure Yang Gong for more than half an hour, and he already had a trace of the idea of completing such an exercise in his mind.

However, Xu Ning not only wanted to complete this exercise, but also wanted to improve it.

After some thought, Xu Ning opened the simulator and started the simulation!

"When you were fifteen years old, you exchanged the Heavenly Sutra for obtaining the mutilated Nine Heavens Pure Yang Gong from the library!"

"After obtaining the Nine Heavens Pure Yang Gong, you want to make up for the Nine Heavens Pure Yang Gong!"

"You practice according to your supplement to the Nine Heavens Pure Yang Gong, and after a month, the power of the Pure Yang burns your meridians, and you are in great pain, and finally you go mad and die!"

......

Seven days later, Xu Ning finally simulated the most perfect fourth-layer exercise of the Nine Heavens Pure Yang Gong.

I have to say that the Nine Heavens Pure Yang is worthy of being a heaven-level exercise, and its practice route is extremely complicated, Xu Ning has simulated it tens of thousands of times, and only one layer has been simulated.

Don't waste time entirely on exercise simulations!

So, Xu Ning decided that half of the time in every day would be spent on cultivation and half of the time would be spent on simulation!

A month later, Xu Ning simulated the fifth-layer exercises, and at the same time, he also condensed the power of one yang, and cultivated to enter the seven-grade realm!

When he was in the Xuanqing World, Xu Ning had Zhou Yuan constantly providing cultivation resources, and there was no bottleneck in his cultivation, and he improved rapidly.

And now, no one provided him with cultivation resources, so he could only honestly absorb the aura in the air to improve his cultivation, so his cultivation improved a lot slower.

Three months later, the sixth layer of exercises was completed, and Xu Ning also condensed the power of the two yangs, and his cultivation reached the fifth grade!

Spring goes to autumn, time flies, and three years have passed in the blink of an eye.

In the study, Xu Ning has grown from a teenager to a masculine and handsome young man.

Xu Ning slowly opened his eyes, and a glimmer of light flashed in his eyes, "After more than three years, I have finally completed all the nine layers of the Nine Heavens Pure Yang Gong. ”

"Not only that, but its power is far beyond what it used to be, and it can be regarded as a heaven-level high-grade exercise!"

"However, I always feel that there seems to be another layer of realm above these nine layers!"

Xu Ning secretly frowned and pondered, in three years, more than 10 million simulations, Xu Ning was already familiar with the Nine Heavens Pure Yang Gong.

After pondering for a moment, Xu Ning seemed to think of something and simulated it again.

Not long after, Xu Ning came back to his senses, and there was a hint of surprise in his eyes, "If that's the case, the power of Jiuyang is unified, and it is the hidden tenth layer of exercises!" ”

In this simulation, Xu Ning actually succeeded at one time.

"The current Nine Heavens Pure Yang Gong should probably be called the Nine Yang Divine Skill, which has surpassed the heaven-level exercises!" Xu Ning thought to himself.

"In the past three years, although I have also cultivated, the improvement speed has not been fast, and now I have only reached the realm of one grade, and I have condensed the power of the six yangs!"

From an ordinary person to a first-class realm in three years, such a cultivation speed is simply unprecedented and unprecedented, but Xu Ning still feels that his cultivation speed is slow!

If you let others know Xu Ning's thoughts at this moment, I'm afraid that I will have the heart to kill him.

"Now, I'm only one step away from the Heavenly Xuan Realm above the first grade! However, the breakthrough movement is too big, and the Wang family is not very suitable! ”

"Moreover, the energy I need to condense the power of pure yang is getting bigger and bigger, the Wang family is not suitable for staying, it's time to go out for a walk!" Xu Ning thought to himself in his heart!

Suddenly, Xu Ning thought that something big seemed to be about to happen recently, and he could take this opportunity to leave the Wang family and go outside!
