Although Yu Si could clearly feel that the power contained in the blood veins in his body began to become more and more condensed, the golden light emitted was becoming more and more brilliant, and his body was becoming more and more tenacious, but the pain was increasing.

"Snort!"

The entire surface of Yu Si's body was covered by the dark red blood shackles. On the surface of the blood flail, there was a large area of blood red that continued to seep out from underneath, but it was quickly evaporated, and some of it turned into a wisp of dark red, which continued to precipitate into the blood flail, and some of it directly turned into blood mist, floating around.

Yu Si opened his eyes with difficulty, but the vision in front of him gradually blurred the outline, and then his body trembled again, because he could feel that the golden light in his body had become ten thousand times stronger at this time, mixed with his own blood, shuttling through his flesh and blood, carrying out the final tempering and sacrifice.

The pain seemed to penetrate the flesh, wrap him up completely, and turn him to ashes.

The severe pain is spreading all the time, eroding all parts of Yu Si's body, and it is also eroding Yu Si's heart.

However, the origin of ice gold will always appear in time, and the luxurious and fierce aura brought by it made Yu Si, who was a little dazed in consciousness, calm down again, clenched his fists tightly, and the roaring sound also completely resounded in his heart. The mind that had been a little vague before also became sober again at this time.

Yu Si roared in his heart, gritted his teeth, and once again endured the all-pervasive heart-rending pain.

The vigorous golden light spread rapidly around the cave, and the erupting golden light and thick mist also continued to have a suppressed roar, like a beast.

The current Yu Si, without interruption, facing difficulties, is his inherent character, and stepping on difficulties fiercely is his cultivation creed.

This process continued day after day before it gradually showed signs of stopping.

All the tendons and veins in Yu Si's body were also like setting off a monstrous wave at this moment, and everything in the sea of knowledge was quietly undulating with the golden waves, and the golden little ding trembled more and more. The origin of the sacrificial alchemy in his body has undergone a qualitative transformation, and it is obvious that he has reached the critical point of sacrificial refining.

Yu Si's face twitched slightly, suppressing the severe pain, at this moment, the bloodline has almost been tempered, and next, it should be the time for the completion of the sacrifice.

However, when Yu Si's mind swept over the dantian in his body, he couldn't help but be surprised, because at this moment, the dantian in his body was actually showing two golden and white light domains, and the two clearly occupied half of the dantian, and in the middle of it, there was an endless golden light emitting out.

Yu Si suddenly felt a shock in his heart, a mouthful of blood spurted out, and his face became extremely pale.

Yu Si's face also became more solemn at this time, and then he concentrated his energy, and hurriedly put all his mind into the consummation of the sacrifice.

With a decision in his heart, Yu Si also immediately began to move, and there was no difficulty for Yu Si at this moment to refine the wisps of gold essence.

I saw that the handprint was flying, and the dantian on the golden light side of Yu Si's body gradually calmed down, and the wisps of gold essence were also controlled by Yu Si's mind, and gradually moved closer to the middle position.

At present, it seems that as long as the opportunity is ripe, and then as long as it is continuously condensed and compressed, the sacrificial alchemy essence will come naturally.

Yu Si felt the subtle changes in the dantian in his body, and in the next moment, his eyes suddenly flashed a touch of fine light, and then the dazzling handprints flew over, and the side of the dantian of the origin of gold in his body suddenly trembled violently, and it looked like boiling water, which was extremely terrifying.

Under the control of the mind, the wisps of gold essence quietly converged towards the middle of the dantian.

Yu Si's hands suddenly clasped together, and then he saw that the wisps of gold essence also trembled suddenly at this moment, and then swept towards the middle, connecting with each other in an instant, and a ring was formed.

At the moment when the wisps of gold essence formed a ring, Yu Si was also shocked, and he only felt that the earth-shaking changes had taken place in his body, and now, the power in his body also skyrocketed, more than several times stronger than before.

Yu Si only knew at this moment how strong the strength he had after the consummation of the origin of gold, but that qualitative transformation allowed all his strength to advance by leaps and bounds.

Next, there is another work that requires great patience and perseverance, that is, to continuously compress the essence of the origin of gold repeatedly, and only by compressing it to the extreme can it be regarded as a perfect success of the successful cultivation of the origin of gold!

However, if you want to complete this work, it is extremely difficult, because it takes a lot of mental attention to guide the wisps of gold essence to refine your body, and it requires a huge amount of spiritual power to continuously squeeze it to make it more brilliant and condensed.

If the cultivator's cultivation is not strong enough, and his mind is not firm, he will end up in failure if he wants to complete the final consummation of the sacrifice.

Yu Si didn't need to worry about these at the moment, because he had previously used the two opposite powers of destruction and repair to refine his bloodline to be extremely clean and strong, and he could completely withstand the impact of the violent power of the gold origin in his body.

Therefore, in the future, as long as there are no accidents, Yu Si can logically complete the sacrifice, it just takes time.

On this day, Yu Si thought about the golden essence qi of this sacrifice, and pointed it out casually, and suddenly a tyrannical cyclone hit the stone wall of the cave at great speed, and a loud bang came, and the hard stone wall seemed to be opened by a thunderstorm.

An extremely manic storm of energy roared out, condensing into a frenzy of power, erupting and roaring, and overflowing the cave with frenzied power.

Gold, wood, water, fire and earth are the root of the five elements, and the five elements are mutually reinforcing and mutually reinforcing, and there are endless combinations. Stack on top of each other to form a new combination of forces.

"Master, at this moment, you can already touch the Origin Spell, and you have reached the power of power that can only be triggered in the late stage of the infant transformation. As long as the master masters the root of the 'number technique', he can use the magic of supernatural powers. ”

Listening to the thoughts from the Seven Treasures Cailian, Yu Si was puzzled, he didn't know why he was able to send out a novel powerful spell similar to Xuan Daozi and Makino, and couldn't help asking, "What is that number technique?"

"This has to start with the origin of the Three Realms...... Mathematics refers to ......"

It turned out that the lord of the domain, the pinnacle of power, opened the world with an axe, and the chaos of the world was clear, distinguishing between yin and yang. The Kun Domain of the Broken Incarnation and the Human Realm is the Human Realm at this moment, forming the earth of the Human Realm.

There are also turbid two gases. The pure air is light and holy, and it rises to the top of Mount Meru to form a realm, which is the heavenly realm at this time.

The turbidity is chaotic and gloomy, and it descends into the ground of Mount Meru, and it also becomes a realm of its own. That is, this world, the Netherworld.

The Netherworld was originally a filthy Chen Ji, and it was originally the pure Chinese realm of Mount Meru and the turbid liquid that was refined was poured here. This is the origin of the Yellow Spring, and the Lechuan River is the Kunmian of the original underworld, that is, the only form that exists in all the underworld. It can be understood that the underworld is the coldest sea. A sea of filth with great attachment and gravitational pull.

The so-called number technique refers to the technique evolved from the principle of restraint of the five elements of yin and yang. In fact, it is to use numbers to represent the attributes of the five elements, all things living in heaven and earth, and then use number operations to deduce the principle of the operation of heaven and earth. It is like the so-called number of all things, with one as yang and two as yin, there is a comparison of "heaven, one earth, two winds, three rains, four or five thunders, six clouds, seven trigrams, eight worlds, nine laws, and ten".

From one to ten, yin and yang can be split, for example, six is three pairs, and seven is one single and three doubles. After splitting in this way, the number of one, three, five, seven, and nine is a total of five single and ten pairs, so it is said that the dry number is five yang and ten yin.

The number of spells is two, four, six, eight, and ten, a total of fifteen pairs, so it is said that the number of the earth is fifteen yin. And Qianzang has ten yin, Kun has fifteen yin, a total of twenty-five pairs, which is the number of fifty of Dayan.

As for how to use these number operations to deduce the principles of the operation of all things, the truth is profound but can be understood without words, and we must have a heart to feel its soul. However, the way of magic is the secret of the operation of heaven and earth, and it can be deduced and calculated, predicting good and bad, and even the foundation of the operation of the formation, which is really broad and profound, and its use is extraordinary.

Qibao Cailian talked about the way of the five elements he comprehended one by one, although it is still difficult to form scriptures that can be explored by Yu Si, but there are also many places that can be used for reference, so that Yu Siyuan can't help but have a little cognition of the things that exist in the underworld. In this way, the so-called accident and necessity have a certain trajectory to deduce.

At this moment, the three platforms in the Yu Si Dantian are more dazzling, and the blue moon is full and bright, clean and flawless, overflowing with green light, and dazzling.

Haoyang and Fang Tian's painting halberds are gradually climbing endless brilliance. Every time he inhaled the surging power of the Origin, the Pill of the Bright Sun became a little fuller. Fang Tian's halberd is a little more transparent and sharp.

Yu Si's new physical body is also approaching perfection, the origin of the five elements alone but the earth is not perfect, and the perfection of the four origin attributes makes the cultivation power in his body climb exponentially. Suddenly, at this moment, his cultivation had reached the level of the Great Perfection in the late stage of the Transformation Yuan, and there was only a thin layer of separation from the infantile transformation stage.

"Yu Si, you're fine. Pan'er, you go first, Yu Si comes with the old man. ”

Xuan Daozi's words interrupted Yu Si and immediately followed him.

After a while, Xuan Daozi took Yu Si to the lush land of mountains and forests, and looked Yu Si up and down again, "Yu Si, have you seen the battle between the old man and Makino? ”

"Sect Master Xuan, what is the supernatural power?" Yu Si felt this body that was not what it used to be, and stared at the three Dao platforms that suddenly appeared in surprise, just as he was listening to the Colorful Baolian explain the supernatural power, he asked again.

"This has to start with the magic practiced by the monks...... And its owner already has the ability to touch the power of the Dao......" Xuan Daozi said eloquently.
