The pupils of Boya and Lin Lijia dilated and spread, dazed, and the outstretched hand hung in the air, and the skin on the hand actually had a kind of glass-like crystal clarity, and there was a faint light seeping out from under the skin, forming a circle of complicated and strange patterns on the surface of the skin, and then disappeared, but after a while, it appeared on the skin of the wrist part, and then disappeared.

In this way, it spread along the arm in a circle, and the whole body was circulated.

"Feel the flow of energy in your body carefully, you only have one chance."

Xin Yuan's voice was like thunder, reaching the ears of the two. The two of them suddenly trembled, their minds cleared, and they forcibly sat their stiff bodies upright like machines, closing their eyes and carefully feeling every movement in their bodies.

Xin Yuan looked at the two people in front of him with a cautious look, and the corners of his mouth slightly curled.

Teaching these two people secret skills is his own considerations, he can't trust the elite combat power left in the Mingyi Society, and it is impossible for him to come forward in person in the future, so he needs some reliable personnel who can help deal with it, so self-cultivation appeared in his first option.

During this time, he has been studying the hidden dangers and injuries in his body, although he has not been able to find a way to completely eliminate these hidden dangers and injuries for the time being, but it is not for nothing, what he has taught these two people in front of him is a special secret technique that he has studied.

In his previous life, he was already a top figure in the martial arts world, but after arriving in this world, after a series of battles and experiences, he began to come into contact with the mysterious knowledge of runes, secret arts, and void eggs, which made his originally stagnant realm progress forward again, so as to better exert his own combat power.

During this time, the process of his retreat was at the same time a process of reorganizing and integrating all his abilities, knowledge and perceptions, and this special secret technique was inspired by this process.

The original source of inspiration was the method of making the Son of the Church of the Ashes, obtained through the Void Egg. The so-called Holy Son is a special group of people cultivated by the Ashes Church in a unique way, usually no different from ordinary people, but at the necessary moment, they can store their consciousness to another level, turn into an empty shell to accept the infusion of the soul power of the strong of the church, become a clone that the strong of the church can overtake remotely, and exert the power of the corresponding strong of the church according to how much soul power is infused.

It seems that the third sect leader who was killed by Han Lei was actually the Holy Son who was controlled by him from a distance. However, there are also ranks among the Holy Sons, and if they can exert the ability of the Third Sect Leader to that extent, such a Holy Son is also rare in the Ashes Church, and it is extremely precious, and I don't know how many years it will take to re-cultivate one.

Xin Yuan naturally couldn't meet the standards of the Ash Church for cultivating the Holy Son, he just gained some insights from the principles of its operation, coupled with his own fighting philosophy, the research of runes and the understanding of the structure of the secret technique, and finally formed this special secret technique, and the flame he absorbed for the two of them was the seed of this secret technique.

The core of the seed's energy is the pollution energy that is constantly oozing out of his body. This kind of polluted energy itself belongs to the interference and transformation of the high-level spiritual level to the low-level material level, which will have an invasive effect on the materialized body, and if it cannot be digested, it is the most violent poison, just like the sparrow that freezes and explodes after staying on Xin Yuan's body. But if it can be effectively digested, then this is the purest and most efficient energy source, but it has a good strengthening effect on the body, like Xin Yuan, it is not that he can't absorb these polluted energy, but this kind of polluted energy is endless, which has exceeded his absorption capacity, which causes his body to be constantly damaged because of this pollution.

Using this polluting energy as the core of seed energy is not a problem, as long as it is not excessive, it will become a source of evolution for seed absorbers.

If Boya and Lin Lizhi can successfully fuse the seed into themselves, then the seed will start to run automatically, maximizing the potential of their bodies and souls at all times, integrating and transforming all the energy they can to strengthen the energy core, so as to simulate the existence of the source fire, and create a simplified structure, allowing them to exert incredible destructive power.

It can be said that as long as the two of them successfully fuse the seeds, they will be able to enter the F rank immediately, and the speed of progress after that is even faster, far faster than any other person in the formal secret arts, and it is only a matter of time before they enter the E rank.

But correspondingly, taking this shortcut that makes people extremely powerful in a short period of time naturally comes at a heavy price.

As long as the practitioner practices this secret technique, then the practitioner will not be able to stop, and once he stops and wants to give up, then the seed core that has been running automatically will have a serious conflict with the body that cannot move forward or even regress synchronously, and the most fragile internal organs of the practitioner's body will be the first to be injured and continue to accumulate injuries, causing the function of the internal organs to gradually fade, and the whole person will begin to weaken rapidly, and eventually die of vitality.

On the other hand, if they have practiced this secret technique, then it means that their limit is to reach the E level, and then they will not be able to advance an inch again. Because they themselves have been assimilated by the structure that represents Xin Yuan's own logic through the seed at the beginning, they can't ignite their own source fire at all, and can only obtain the power of Xin Yuan's unique source fire through simulation, in this case, they can reach the level of E level at most, which is a big level behind Xin Yuan, unless Xin Yuan goes further and optimizes the structure of the seed in essence, otherwise they can only stay at E level forever.

However, these shortcomings are not shortcomings for Xin Yuan at all, the secret technique is just a tool he uses to cultivate his own power as quickly as possible, these defects can allow him to better control the people who practice this secret technique, there is never a foolproof thing in the world, and it is not a bad thing to keep one more behind.

After waiting for two hours, Boya finally woke up first, and more than ten seconds later, Lin Lizhi also opened his eyes, and the eyes of the two were full of energy, like starlight from the sky, as if the whole person had a good rest and became refreshed.

Lin Lizhi's eyes suddenly flashed a shadow of a cross star, his right hand pressed on the floor, and as soon as he grabbed it, his fingers went deep into the wooden floor without resistance like pinching tofu, and then he easily pulled it up, only to see countless sawdust fluttering down the cracks between his fingers.

"This power...... It's amazing! Lin Lizhi muttered, clenching his fists and slowly letting go, "I feel the ...... that is constantly circulating in my body Incredible......"

Xin Yuan looked at Boya with a smile, only to see that she didn't know what she was thinking. After a few moments, an invisible flow of air flowed around her, and then she raised her right hand, her fingers spread out, as if holding something, and the visible trace of air flowed between her fingers, as if it had a life of its own, and it was wrapped around her palm.

A shadow of a cross star also flashed in her eyes, and in an instant, her right hand had been silently stabbed out and withdrawn, and if it were an ordinary person, she would not have noticed that her hand had moved.

Call!

A second later, the space where her hand had pierced suddenly resounded with the whistling of the wind, which was the one she had stabbed before, even cutting through the air, creating a temporary vacuum.

Bang Bang Bang!

Xin Yuan applauded, his face full of appreciation.

This is the true power of this secret technique, once activated, it can generate terrifying piercing and cutting power by shaking the air on the outer edge of the hand, and it is not limited to air, any matter that exists can be affected, and when practiced to the extreme, it can even induce spatial tremor to complete the spatial cutting.

Seeing that the two of them were obsessively studying their newly acquired strength, Xin Yuan smiled, knowing that they could not come out of this state in a short time, so he got up and walked outside.

Just as he came to the door, Boya's voice suddenly came from behind him.

"Social ...... No, teacher, what's the name of this secret technique you taught me? ”

The door opened, and the sky was filled with stars.

He looked up, paused, and walked out.

"Let's call it the Pole Star Cross."

As the words echoed, his figure had disappeared from the door.
