In a secret room somewhere in the temporary residence of the Refining Pavilion.

A bald monk with strong muscles, naked on his upper body, lying on a platform, with a small pit in the center of his chest, and the flesh and internal organs in it were protected by a pale cyan aura.

The bald monk looked fanatical and stared at the sky.

There was a long, flat bone that was wide at the top and narrow at the bottom, scorched by a reddish flame, and this bone was the sternum that had been torn off from the chest.

Yu Xuan stood not far away, his hands burning with dark red flames, or pressing or kneading several blood condensation grasses, which turned into grains of powder at a speed visible to the naked eye, and were thrown into the air by him.

Zhu Siming and Qin Yushu surrounded the bald monk, constantly pinching various legal decisions in their hands, and a very vigorous ball of essence blood and blood condensation grass powder fused together, and under the drive of one after another, it sank into the sternum in mid-air.

Gradually, subtle lines begin to appear on the surface of the sternum, like the intertwined blood vessels on the human body.

Qin Yushu and Zhu Siming looked solemn, as refining masters, it is not difficult to portray this kind of pattern, the real difficulty lies in the depiction at the same time, to protect this sternum of ordinary material.

After about half an hour, the lines on the sternum were completely formed.

If you zoom in, these lines resemble intertwined blood-red furrows, all of which meet at the sternal stem, where there is a circular groove.

After completing the depiction of the lines, Qin Yushu and Zhu Siming glanced at each other, and the two divine thoughts of the knot stage were quickly intertwined, turning into a powerful god thought at the peak of the knot dan.

Then Zhu Siming waved one hand, and a blue and black, bean-sized golden pill emerged.

One after another, the mystical and incomparably mysterious law decisions, under the control of the huge divine consciousness, hit Jin Dan.

Jin Dan trembled quickly, and streams of black mist emerged from it, and Jin Dan shrank at a speed visible to the naked eye, although the aura was weakening, it gradually exuded a pure water attribute aura.

As soon as Zhu Siming's method turned, this shrunken water attribute golden pill shot towards the sternum in mid-air, just stuck in the circular groove on the sternum handle.

Qin Yushu then threw out a bunch of water-attribute mid-rank spirit stones, surrounding the sternum, and under the spell of the two of them, these spirit stones turned into a rich blue mist, enveloping the sternum.

Zhu Siming's expressions became more and more serious, and the law was constantly changing, and one after another spiritual light hit the sternum, and the blue mist slowly condensed inward.

It took a full day for the blue mist to fully merge into it, revealing a brand new sternum.

At this time, Xiao Jindan had disappeared, and the blood-red ravines on the surface of the sternum were all filled with a blue material, forming a unique vein, and the surrounding water attribute aura appeared to be very active.

Zhu Siming said in a deep voice: "Monk Fang, the last step is up to you." ”

Looking at the bald monk's firm and fanatical eyes, Zhu Siming waved lightly, and his sternum fell downward, properly stuck in the center of his chest.

At the same time, Qin Yushu took out a jade bottle and poured the remaining blood inside around the sternum, the connection points between the bones.

The dazzling blue light shot up into the sky, printing the bald monk's strong body blue.

"Ah......h

The bald monk let out an excited roar and covered his chest with his hands.

The muscles of his whole body twitched, and the power of rich qi and blood rose up, and a large amount of bright red essence blood in his body converged towards the position of his chest, intertwined with the blue aura.

The blue aura seemed to show a strong sense of repulsion, and if he wanted to get out, he could be pressed in place by the bald monk.

At this time, the surrounding water-attribute aura seemed to be extremely active, and there was a tendency to converge towards the sternum.

Zhu Siming and the three of them looked at this scene nervously, their consciousness lingering outside their sternum.

"Click......" A faint bone cracking sound came out, and the bald monk seemed to be aware of it, and a complicated look of regret and satisfaction flashed in his eyes.

The next moment, the blue light in his chest burst out, and a not weak energy exploded, and his sternum exploded directly.

The bald monk's strong body was torn apart by this energy, flesh and bones, and stumps were scattered around, and the secret room fell silent for a while.

......

After a long while, Qin Yushu sighed and said, "Although we have perfected the miniature magic circle and reduced the material requirements, when the final fusion is made, the sternum will not be able to withstand the energy impact of refining and fusion. ”

"Monk Fang's sternum is already one of the best among the outer disciples, and the thirty years that the pavilion master said may not be enough. ”

Zhu Siming reviewed the process just now, and said slowly: "Yushu, the current progress has been very fast, you must know that we couldn't even refine the sternal weapon spirit root successfully at the beginning. ”

"The last few disciples have all reached the stage of final refining and fusion, but these few failures, apart from the problem of materials, seem to have something ......."

Zhu Siming couldn't help but fall into deep thought.

Yu Xuan on the side did not participate in the discussion, dozens of dark red sparks popped out in his hands, burned the stumps in the secret room into ashes, received these ashes into a jade bottle, and solemnly put them away.

This Monk Fang is already the fourteenth martial artist who has voluntarily tested the spiritual root.

These martial artists are all top-qualified among the outer disciples, and they have long cultivated the Vajra Duel to the highest level, and the degree of tempering of the sternum is also extremely high.

It's a pity that they started early, and they only began to temper their sternum in their sixties, and with these twenty years of cultivation, their lives are about to come to an end.

In order not to leave regrets, these top martial artists all took the initiative to ask for the test of the Instrument Spirit Root, and even if they failed, the experience of the fusion of the Instrument Spirit Root could be left to future generations of martial artists.

As long as there are martial artists who successfully generate the spiritual root of the instrument and refine the body and cultivate the immortal with the body of a mortal, then their sacrifice will not be in vain!

It is also thanks to Lu Kun who fished in troubled waters in the Qi War and sent back a lot of golden pills, otherwise even if there were martial artists who volunteered, they would not be able to carry it out, because in addition to various materials, the refining of the spirit root also needs to consume golden pills.

In the past six months, although there were fourteen martial saints whose combat strength was comparable to that of the late stage of qi refining, and fourteen golden pills were destroyed in the test, the success was very significant.

The generation of the Spiritual Root is stuck in the final fusion stage.

Zhu Siming suddenly thought of something, and his eyes lit up: "By the way, did you feel it just now, Monk Fang attracted the surrounding aura at the last moment." ”

Qin Yushu was slightly stunned and muttered: "That's right, the water attribute aura has been guided, and this can only be done by the real spiritual root, and the previous few martial artists did not have this phenomenon." ”

Zhu Siming frowned: "How did Monk Fang do it, he was obviously one step closer than the others. ”

At this moment, a terrifying divine thought descended on the secret room: "Could it be because of the essence blood?"

"The Pavilion Master is back?"

"Master!"

Zhu Siming made a decisive move in his hand, opened the ban in the secret room, and a burly figure appeared in front of everyone.

Lu Kun walked in, looked at the jade bottle in Yu Xuan's hand, and sighed, "Not long after I came back, I happened to observe the whole process. ”

"Monk Fang seems to have created a certain physical body method, condensing the essence blood of the whole body in his chest, trying to accelerate the fusion of the sternal organ spirit root with the vigorous essence blood. ”

Lu Kun said regretfully: "It's a pity that Monk Fang has reached his twilight years, and his essence blood is not strong enough to resist the power of the spiritual root, and the material of the sternum is not enough, so he fell short in the end." ”

Zhu Siming heard Lu Kun's analysis, and his expression moved: "Essence blood, could it be that the pavilion master has thought of a solution?"

Lu Kun shook his head: "I don't have a clue about the specific method of refining and fusion. ”

He paused, then continued: "However, there is a disciple who is very suitable for the test of the Instrument Spirit Root, if this person comes to the test, even if he fails, his life will not be in danger, and he will definitely bring us greater inspiration." ”

The others looked at each other, not knowing who Lu Kun was talking about.
