After a whole day of comprehending his cultivation technique, Ling Xu's progress had advanced from 63% of great success to 68%.
Although it could seem like nothing, he noticed the difference as his speed of circulating his blood qi became faster than before.
Next he would resume on starting the second stage of the technique.
At the end of the second week since he left the tutorial and everything begun, Ling Xu was beginning his practice of the second stage of the Blood Thread Transformation technique.
With his increased control over his blood qi, after transforming it into a dual stream, it wasn't difficult to progress.
Passing through his heart, Ling Xu moved the dual threads of blood qi as they slowly started to rotate between each other.
It all seemed easy, but once the beginning of the dual threads was linked together in this rotating motion, Ling Xu realized the problem the manual had advertised before.
As the rest of both streams of energy passed through the heart, Ling Xu felt his blood qi draining incredibly fast. While enhancing the pressure from his heart, the consumption of his blood qi needed to complete this process was immense.
"Ufff, ufff…"
Sweating profusely, Ling Xu became perplexed at the difficulty
"With my current capacity of blood qi this will probably take months before it is finally completed. I can't believe that exhausting all my blood qi barely helped me rotate an insignificant length from the dual threads."
He felt his blood qi and he could barely perceive the tip of both streams of blood qi rotating as the length was imperceptible.
"I have already started practicing this technique so I can't go back now, there have been no news from the system up until now so I have nothing else to do more than advance with what I can."
…
After a few more hours, Ling Xu started to feel the length of the dual threads rotating a little more as he had repeated the cycle of rotating them using his heart's pressure, resting his heart and recovering his blood qi.
He was now doing it for the last time of the day as the sun was already setting on the horizon and Ling Xu was going to eat before going to sleep.
Rotating where he last left, Ling Xu suddenly felt the path between his eyes open as the feeling of his mind becoming clear came.
"I have been waiting so hard for this, now that the problem has gone I can complete this stage tonight."
Feeling a stream of pure energy swimming in his body, Ling Xu was ecstatic as with the coming of it his blood qi would now recover insanely fast.
His mind entered this ethereal state and Ling Xu's blood qi threads started rotating after they left the heart.
The sound from his blood qi circulating incredibly fast could be heard louder and louder, as the longer time passed more and more of his blood qi entered this rotating motion that increased its circulating speed even further.
…
It was one in the morning when Ling Xu's body came back to normal.
Once his mind came back, Ling Xu's eyes opened wide in shock from the new changes he could feel already.
Feeling his blood qi moving naturally almost as fast as when he circulated his blood qi to refine his body, he felt that his strength had improved once again.
He then circulated his blood qi using his Basic Blood Circulation technique to refine his organs and he could clearly hear the sound of his blood qi out of his body.
Now that the dual threads of blood qi had started to rotate in unison, the speed of his blood qi increased to the point that Ling Xu could feel the strength of his body increase as if he had advanced into the next stage of the Blood Qi realm.
[Name]: Ling Xu
[Realm]: 6th stage of Blood Qi (30%)
[Cultivation]: Basic Blood Circulation (great success 63%), Existence Shadow Will (8,81%)
[Techniques]: Blood Thread Transformation (second stage 100%)
[Skills]: Enhanced Synapsis (high grade), White Heavy Strike (high grade), Swift Steps (middle grade), Copper Skin Iron Bones (middle grade)
Not even a minute had passed but as Ling Xu opened his status panel he realized that his realm had progressed 1%.
It was obvious that the transformation of his blood qi not only improved his combat power but even the speed at which his body could be refined.
Coming out of his excitement, Ling Xu thought about his Existence Shadow Will technique which he didn't know much about.
"After waiting for this cultivation technique to activate its ability for the second time already, I know that the path between my eyes will open once every week. So I only have to wait for another week until I am able to complete the Blood Thread Transformation technique."
…
The next day, Ling Xu tried to start the third stage of the technique but after less than a minute he had to stop.
"Ugh!!!"
He felt his heart in excruciating pain as he had overexerted its strength.
The third stage of Blood Thread Transformation technique consists of merging both dual threads while rotating them into one and putting them under the extreme pressure of the heart.
But not only does it spend an insane amount of blood qi to the point that after a few seconds Ling Xu's blood qi reserves had become as thin as a paper, but the pressure that his heart needs to exert for the rotating dual threads to merge is extremely high.
This was to the point that Ling Xu realized that unless he completed the stage of organ refining and entered the seventh stage of Blood Qi, he wouldn't be able to even start the merging process of the threads of blood qi.
The rest of the day Ling Xu decided to recover as he felt it would be impossible to progress much in his realm as one of the most important organs, his heart, was in no state of going through the refinement process.
In the following days, Ling Xu ate, enjoyed his daily walk and refined his organs once again after feeling that his heart had recovered its strength.
This time, he lowered the time he took to refine his body as he realized that it wouldn't take long before he completed the sixth stage.
…
His guess wasn't wrong as on the last day of the third week, Ling Xu had already completed the stage and reached a 100%.
His current strength couldn't be considered anything more than monstruous as Ling Xu once tried in a black alley to punch a thick wall of concrete and ended up destroying it to the ground.
The commotion was quite big as he decided to run from the scene in case someone decided to come and see what the noise was about.
Now he was continuing the refinement of his body as he felt that something was missing.
Ling Xu felt that he could advance any time and breakthrough to the seventh stage of Blood Qi, but he never tried in the last few days as he felt that his organs could still be tempered as if they hadn't reached their limit.
With his current refinement, Ling Xu's skin was invulnerable to attacks from low grade weapons and his organs had become very strong and solid. Ling Xu felt that even if it snowed he would become cold as he had become resistant to heat and cold.
Even his immune system had increased as Ling Xu never felt, not even once, ill or anything similar since he exited the tutorial.
…
After three hours of refining his organs, Ling Xu was waiting for the opening of the path between his eyes that still didn't come even after the sun had come down and it was midnight.
About to stop circulating his blood qi a change occurred.
"It really is once a week!!"
Letting his body move on its own, Ling Xu realized that his mastery of his cultivation technique was increasing once again.
That wasn't all as his organs had finally shown a sign of being fully tempered as they had stopped strengthening.
An entire hour passed until the increasing mastery of Ling Xu's cultivation technique made a commotion.
Ling Xu's mind was disturbed as it came out of its pacific state, feeling his blood qi following its own rhythm as if it was alive.
With its increase in speed after reaching the second stage of Blood Thread Transformation, his blood qi suddenly started to reach parts of the body that they had never passed before.
Unblocking every extreme of Ling Xu's body, his blood qi made a natural cycle as the refinement of his body had deepened. His blood qi seeped his organs as they started to break free from their own limit.
They started absorbing crazily his blood qi as the golden stream of energy helped in recovering it, compensating the insane speed of absorption that would have suck him dry if not.
For a few minutes, Ling Xu's body was entangled in a dangerous balance between his organs absorbing his blood qi madly and the stream of golden energy helping him recover it.
But once it ended, he felt incredibly strong as his organs had started to feed back to the rest of the body a purer and more refined blood qi.
This wasn't the kind of strength that came from simple raw power from the muscles.
It was the strength that came from having his blood qi become refined twice, once by his muscles and once by his organs just now.
Ling Xu felt a few seconds ago that the path between his eyes had closed as the stream of pure energy had stopped entering and it was becoming thinner every second.
"There is still time to breakthrough, my blood qi is already at its peak with the help of this energy."
Continuing the circulation of his blood qi, it completed a natural cycle after another as he felt that his organs had started to absorb his blood qi once again.
This time, the process wasn't as hard as entering the peak as the amount of blood qi his organs demanded wasn't as intense.
Everything progressed smoothly and Ling Xu felt another movement as he felt his organs strengthening one more time.
He opened his eyes feeling the increase in his body's capacity of blood qi with extreme satisfaction as he revealed a crescent smile.
Opening the status panel, Ling Xu observed several changes.
