"The Great Heavenly Derivative Sutra," Xiao Han said silently.

This is the foundation building technique passed on to him by the Emperor of Man 10,000 years ago.

It is rumored that the Great Heavenly Derivation Sutra is the first volume of the Complete Book of Heaven and Earth.

The roots of the Book of Heaven and Earth can even be traced back hundreds of millions of years to the age of the Apocalypse.

The beginning of the mixed element, the beginning of the heavens.

That era of all saints and emperors coexisted and was extremely glorious.

"The Complete Book of Heaven and Earth" is the supreme practice created by the joint efforts of several emperors in that era.

It's a pity that after the Apocalypse Era, there was a melee between the Ancient and the Ancient, and this volume of supreme exercises was also lost.

Back then, Emperor Tianyu was also by chance, in an ancient forbidden place, found a fragment of mixed Yuan Tianque suspected to record the "Complete Book of Heaven and Earth", and after several years of deduction and improvement, there was the later "Great Heaven Derivative Sutra".

"Heaven is invisible, all things are born, and the world is derived from the ...... by incarnating the heavens"

Xiao Han held his breath and condensed, and quickly ran the "Great Heaven Derivative Sutra".

The Xuanwu world respects martial arts, martial arts cultivation, and the ranks are also extremely strict.

The first realm of a martial artist is called the Xuanqi Realm, and then there are the Xuanling Realm, the Taixuan Realm and the Xuantian Realm, and these four great realms are collectively called the Four Great Realms.

Among the four major Xuan Realms, in addition to the Xuan Qi Realm, which is divided into nine small realms, the Xuan Ling Realm, the Taixuan Realm, and the Xuantian Realm are all divided into six small realms: the early stage, the middle stage, the late stage, the small Cheng realm, the Great Cheng realm, and the peak.

The tutors of Cangzhou Fengling Academy are mostly powerhouses in the Xuanling Realm, and only a few senior tutors have reached the Taixuan Realm.

It is said that in the entire Cangzhou, only the dean of Fengling Academy and the city lord of Cangzhou City have reached the Xuantian Realm.

Ten thousand years ago, when Xiao Han was sealed, although he was only fifteen years old, his cultivation had already reached the peak of the Xuantian Realm.

However, it is a pity that Xuan Qi is one of the origin substances of heaven and earth, even if the existence of the Emperor of Heaven and Earth cannot seal the origin of heaven and earth.

In order to seal it for 10,000 years, Xiao Han had to disperse and cultivate.

Xiao Han held his breath and condensed, and quickly ran the "Great Heaven Derivative Sutra".

The Xuan Qi Realm opens up spiritual veins in the body, condenses the Xuan Qi of Heaven and Earth, and initiates the True Qi, so that the strength of the physical body becomes stronger and stronger, and every time it breaks through a small realm, the strength will increase by a large section.

Under normal circumstances, after cultivating to reach the Xuanqi One Heavy Heaven, there is a stone of power, which is what we usually call a hundred catties.

The gap between the Xuanqi First Heaven Martial Artist and ordinary people is not large, but with the improvement of cultivation, this gap will naturally become more and more obvious.

Xuanqi Dual Heaven has two hundred catties;

Three hundred pounds in three days;

And so on, until the ninth heaven of Xuanqi, he has nine hundred catties of strength.

Of course, this only refers to the general situation, and there are also non-ordinary situations.

Some people practice high-level exercises, and the Xuan Qi they absorb is extremely pure, and it also increases the strength of the physical body.

For example, the "Heavenly Emperor Decision" that Xiao Han cultivated ten thousand years ago was an emperor-level exercise, and as a result, every time he broke through a small realm in the Xuanqi Realm, his strength increased by nearly one hundred and forty catties.

And the level of the "Great Heavenly Derivative Sutra" even exceeds the "Heavenly Emperor Decision" of the Tianyu Emperor, and the Tianyu Emperor once suspected that the "Great Heavenly Derivative Sutra" may have reached the legendary level of the Immortal Sutra.

"The way of the great heavens is formless and selfless. ”

He sat cross-legged under a boulder, holding his breath and concentrating, seizing the time to absorb the Xuan Qi.

The wind howled, the lightning thundered, the rain became heavier and heavier, and the whole canyon was shaken in the storm.

Xiao Han, who was hiding under the boulder, was calm and unaffected by the outside world.

Time passed slowly, and the night finally passed.

The clouds cleared, the rain cleared, and a rainbow hung in the distant sky.

After this storm, the entire canyon regains its amazing vitality, lush greenery, lakes and mountains, and picturesque views from afar.

Xiao Han let out a long breath of turbid air and slowly opened his eyes.

"Xuanqi Four Heavens!"

Xiao Han was speechless, he was cut off eighteen meridians in a row, he originally thought that even if it was repaired, he could only keep the cultivation of the two and three heavens of Xuanqi at most, but he didn't expect to be able to keep the cultivation of the four heavens of Xuanqi.

It's nothing short of a miracle!

The meridians of the others were cut off, and even if they were cured afterwards, their cultivation would be nullified nine times out of ten.

And he even repaid nearly half of his cultivation.

Now that he had Xuan Qi in his body as support, Xiao Han felt that his whole body had inexhaustible strength, and he used all his strength to punch the boulder in the back of his body.

"Boom!"

Gravel splashed, and a huge boulder instantly turned into a pile of rubble.

According to conservative estimates, he should have six hundred catties of strength by now.

The Xuanqi Four Heavens have a strength of six hundred catties, and it is estimated that it will scare a large number of people when they say it.

You must know that ordinary Xuanqi Quadruple Heavenly Martial Artists only have the strength of four hundred catties, but Xiao Han has half the strength of them.

"The initial purity of the Heaven and Earth Xuan Qi that I absorbed is inevitably too pure! ”

"No wonder my father suspects that the Great Heaven Derivative Sutra is the first volume of the "Complete Book of Heaven and Earth", and the initial Xuan Qi absorbed is so pure, even if it is not the "Complete Book of Heaven and Earth", it is estimated that it is also a practice comparable to the "Complete Book of Heaven and Earth". ”

Ten thousand years ago, Xiao Han cultivated the "Heavenly Emperor Decision", and the initial Xuan Qi he absorbed was also very pure, and every time he opened up a spiritual vein, his strength increased by about one hundred and forty-five catties.

For example, when he broke through the Xuanqi Triple Heaven, he increased his strength by one hundred and forty-eight catties, and when he broke through the Xuanqi Fivefold Heaven, he increased by one hundred and forty-nine catties, and when he broke through the Xuanqi Sixth Heaven, he increased his strength by one hundred and fifty catties.

And each realm of the Great Heaven Derivation Sutra has maintained a 50% increase, which is very against the sky.

Xiao Han closed his eyes, took a deep breath, and quickly stabilized his mind.

Great joy and sorrow are all taboos in martial arts, and only with a changing state of mind can a warrior go a long way.

He knew that the reason why he was able to reach the Xuanqi Quadruple Heaven so quickly was not only due to his own cultivation of high-level exercises, but also related to his previous foundation.

After all, he used to be a Xuantian Realm powerhouse, and he had already walked the road once, and if he walked it again, it would naturally be much easier.

It's like a thirsty lake, which can easily be re-formed by pouring rainwater.

Xiao Han slowly exhaled a breath of turbidity, opened his eyes, and said to himself, "I disappeared for a day and a night, and I don't know what happened to Xiaoxuan." ”

Now that he has seen Mu Xiaodie as a person, intellectually, he should disappear and lie dormant for a while.

With the cultivation speed of the Great Heaven Derivation Sutra, within a few months, he would be able to resume his previous cultivation.

However, he couldn't wait that long.

He couldn't let go of the concern in his heart.

After coming to 10,000 years, all the old people in the past have died, even Song Qingyun, who has adopted him in the past few years, has left him.

In this world, his only relative is only a sister who suffers from congenital diseases.

This is his only concern in this world, and no matter where he goes over the years, he will take Xiaoxuan with him.

Now Xiaoxuan is still in the Mu family of Fengling Academy.

Since Mu Xiaodie can abandon him without thinking about his previous merits after he loses his effect, there is no reason to continue to leave Xiaoxuan to live and eat with her for nothing.

Xiao Han's eyes were cold, and his face was like an ice cellar: "Mu Xiaodie, I can bear whatever you do to me, but if you dare to touch Xuan'er, I promise, it will definitely make you pay a heavy price." ”
