The Tatsuya Library was something not even the elders of their Clan could freely enter. Only Ryu and a select few others could since he was the son of their Patriarch and the grandson of their Saint.
This was to say that knowledge was very important to those of the martial world, so much so that it surprised Ryu that it was so easy to enter the libraries of the Radiant Star Sect, and even more surprising that no one was taking advantage of it.
However, Ryu wasn't one to bother with the stupidity of others and the matter related to him killing a disciple had already been forgotten by him.
After learning how the books were organized, he quickly found several books on the topic of soul and soul talents. When he opened the first, he was surprised to find that he actually didn't know as much as he thought he did. Or, rather, Sacrum was far more in the dark than he believed. It seemed that there were some talents that simply didn't appear in Sacrum at all.
It wouldn't be until Ryu left this section to read up on lower level worlds that he would come to understand.
According to the books here, lower level worlds could sometimes breed talents that were high level, but they would be restricted by the weakness of the world's Heavens and its Fundamental Runes. Essentially, Ryu's current talent was no less in substance in comparison to a true Phoenix Bloodline of the True Martial World, the issue was that it was born under the weakness of Sacrum and was thus shackled.
If one wanted to undo the shackles of their Bloodline or Talent from a lower world, they had a lot of trouble to go through, and there were different methods depending on what Talent you wanted to unseal.
For Bloodlines, as an example, the best methods were beast meat, Body Realm Cultivation pills and Beast Cores. This was in order of most efficient to least efficient.
It was also important that the class of the beast be exceptionally high. And it was at this point that Ryu realized that he had made a foolish error in judgment.
The Astral Ship he had been on hadn't fed him Heaven Grade beast meat like he had thought. Rather, it had fed him Black Grade beast meat. The difference was that these Black Grade beasts had been in the Immortal Ring Realm, or rather, the Seventh Order.
For Ryu, who had come from Sacrum, the idea of a Black Grade beast reaching the Seventh Order was unheard of. And, the beasts that he was used to did carry nearly the same pressure as beasts from the True Martial World. So, he had made an error in judgment with his eyes sealed.
But, this wasn't entirely Ryu's fault either. The Astral Ship had advertised it as Heaven Grade meat, and even the Sky God beauty that had served him also thought it was Heaven Grade meat as well. However, it was clearly a piece of false advertising, known to fool those like Ryu who came from smaller worlds.
Of course, now that Ryu thought about it, the advertisements weren't for Heaven Grade meat, it was more like "Heavenly Meat". Even if he went to complain, the Twin Phase Merchant Group would have plausible deniability.
Ryu couldn't help but shake his head. When had he, Ryu Tatsuya, ever been fooled like this before?
Still, this was still a bit of good news. After suffering at the hands of Common Grade beasts like he had, if so much Heaven Grade meat could only unshackle his Bloodlines to the Black Grade, it would be too exaggerated.
'So, three months worth of Black Grade meat at the Seventh Order was enough to push my Bloodlines from the Peak Common Grade to the Lower Black Grade… I'll either need stronger Black Grade beasts, or I'll have to see if I can find some Earth Grade meat… Or…'
There were two other options, and that was, of course, Body Realm Cultivation pills or Beast Cores.
Beast Cores were the most efficient, especially those with Dao Runes. If Ryu found a single Black Grade Beast Core was a compatible Dao Rune for his Fire Dragon Bloodline, for example, he could instantly unshackle it to the Higher Black Grade. If he was lucky, maybe even the Peak Black Grrade.
As for Body Realm Cultivation Pills, they had to be for the Blood Tempering Realm.
Ryu had fallen out of the Blood Tempering Realm and back into the pinnacle of the Vessel Tempering Realm after his Rebirth, so these pills were perfect for him. Due to the point he was in his cultivation, it also wouldn't raise any suspicion unless he went overboard.
Unfortunately, unsealing his other talents would be far more troublesome, especially his Bone Structure.
According to the books, in order to unshackle Bone Structures, one could only use two methods: Beast Cores and Dao Bones.
Dao Bones were even rarer than Dao Rune Beast Cores were. Beasts with Dao Bones had had their Dao Rune Beast Cores for an extended period of time and managed to transfer some Dao Runes to their bones, multiplying their power several times over.
Ryu's Ice Jade Crystal Body was actually considered to be at the Peak Black Grade currently, potentially due to his rebirth or its mutation, Ryu wasn't sure. But, if he wanted to break free of its current restraints, he would need to absorb compatible Beast Cores, preferably ones with Dao Runes, and it would be even better if he could absorb Dao Bones.
While unshackling Bone Structures was troublesome, unshackling Meridians was quite easy… Sort of.
Unshackling Meridians required nothing other than cultivating with high level qi of the True Martial World. The more quality qi your Meridians were baptized with, the better.
For Ryu, who had access to the Chaos Plane of the True Martial World, this wasn't difficult. In fact, so long as he started to cultivate once again, it wouldn't be long until his Meridians directly broke into the Heaven Grade.
The bad news though…
