William waved a series of hand seals in accordance to his technique and muttered, "Yin Spirit Ki Extraction begin!"
He then began a certain set of breathing. With each breath in, a large amount of the grayish misty spiritual Ki of the Spirit Enhancing Yin Flower was taken in through his two nostrils.
Then breath out, expelling foul particles. Like that, he began his Spirit Ki cultivation.
William had already learned a lot of Cultivation techniques. But they were useless to him as his meridian was a complete mess. All the techniques he learned from the Red Dragon kingdom were Yuan Cultivation techniques and he couldn't cultivate any of them.
However, recently with the stroke of luck, he had laid down a strong foundation for Spiritual cultivation with his heart as a foundation.
Yuan qi cultivation was Qi cultivation whereas Spirit Cultivation was mainly based on body cultivation and used Ki as the source of energy.
Cultivating the Spirit Ki was many times harder than cultivating Yuan Qi. So, the old dragon trapped in his pendant even considered and accepted William as his disciple laid down the Legendary Primordial Spirit Root in his heart as the core. There were many other spirit roots and their ranking varies. But the old dragon had only heard of such things in ancient records, he even himself only managed to lay down Heavenly Spirit Root.
So, the first time he witnessed it, he decided to take in William as his disciple decisively.
Laying over the vast world of the pendant, the large luster black dragon watched over the youth, ready to guide any moment he made a mistake.
"Good! He becoming more familiar with the technique. I thought he would take a few days to learn and master it." The dragon muttered praising his disciple. "Thank goodness, he is a human and his comprehension is qualitatively higher than even those sages of the Human Clan."
Feeling satisfied for getting such a great disciple, he added, "For Spirit Ki cultivation, I give him Yin-Yang Dragonic Technique. And I can proudly say that if this self created technique of mine which took me my whole life, blood and experience is number two under the heaven then there will be no technique with rank number one. On the other good point, this technique is perfect for my disciple, more like it was created just for him."
Thinking about that and imagining the youth's growth in the future made him prouder and prouder.
His dragon sense was still observing everything happening inside William. He saw the large amount of grayish Yin Ki were gather with William's thumping heart. As he continued, the mist got more concentrated and pressed, compressing them into his blood.
Those blood left the heart through those blood vessels and began to strengthen his body. A small portion of the blood carrying those grayish Ki began to destroy those messed up meridian and began to reconstruct a brand new meridian. It was a very small process.
"Oh! At this rate, he would possibly able to heal and reconstruct a brand new meridian after a year, then I need to give him a Yuan Qi Cultivation technique perfect for his Dragon Meridian. I better start scorching through all techniques and scrolls I have collected throughout my life."
The next instant, he roared and spat out a reddish ball which turned into a gigantic door hanging in the air.
"Open!" he said and the door opened. At first, a strong Yuan Qi blasted out from behind that door, the dragon devoured all of them like drinking immortal elixir.
The next thing when all those yuan qi entered his stomach, a large amount of scrolls, books, weapons and many things began to pour down.
Mountains of treasures of all kind began to pile up inside the world of pendant.
If William's mind were to visit this place again, he will be bewildered to see the new topography with mountains and mountains of treasures.
Treasures of all kind still continued to pour down without end.
The old dragon stood up and began to search through all of them.
At one time, he would read some scrolls and tossed them away like some trash. Then his boring days of slumbering ended, replacing with finding a proper cultivation technique for his only disciple. He was now motivated to search and read all of them.
Before his eyes were dull, now they were radiated with new zeal of life. Once he considered William as his disciple he had already consider him as his own. In the vast universe, even though he was the great primordial black dragon, he had none to call relative. Now William was his only relative.
On the outside world, William cultivated for two hours and stopped only when all the Yin Ki in the room was drain to the last particle.
He stood up and began to flex his muscle. He grinned as he felt a strange strength coursing all over his body.
He really wanted to test them how strong he had become. So, he began to exercise all martial techniques he mastered as an assassin in the previous life.
At first, he started with boxing. Then he added kick boxing. Next he changed into Shaolin Styles, Kung Fu, Mu Thai and went one, transitioning from one style to another.
As he executed all of those moves he felt quite exhilarating as he was now able to perform all of them even better than when he was the prime assassin of his previous life.
"Oh! Now I really want to fight a strong opponent. If I'm like this and fight uncle Shanon again, I've a chance of beating him within an hour when we fought with equal strength." He said, "Anyway, if I fought him without any restriction in his cultivation, I believe a single breath from him could crush me into meat paste."
Although, the old dragon was scorching through his treasures, one of his Dragon sense still observing the youth. After seeing all those martial styles of various school made him to stop and turned to him.
His mouth agape for a moment and spoke with interest, "Ah! Those martial styles! I've never seen them before. However, all of them could be rank in the top grades in terms of fighting skills. This little mouse is strange. There is no way anyone from this little world could mastered and taught them to him. Even I felt threaten from some of those styles. If someone of my level with equal strength use them, I won't even last ten moves. I need to watch my little disciple and learned the essence of those styles. I was even thinking about giving him my strongest martial styles to him. But forget it, now I want to learn his instead."
Yes, through countless years all those martial geniuses, sages, warriors of earth had honed those styles and developed to those level. So no doubt they reached those level even though none of them were cultivators or immortals.
