"Let's start the explanation with the soul grade items."
"Soul items are extremely rare in the world as it attaches directly to your very soul, and information about it is also almost nonexistent. But brat, you are lucky that you are talking with me, because I also had a soul item when I was alive and am the few who knows more about them." Old Man Hanxian said with a proud expression.
"Oh, by the way you would never be able to separate with those two soul items now since you have already formed a bond with them, until and unless you die." He spoke.
Kai nodded seriously in understanding. When he dropped his blood on the items, he did get an inseparable feeling so he didn't doubt the old man's words.
"As of their grade… well the soul grade is both the best and the worst grade." The old man said.
"Huh… both the best and the worst?" Kai questioned.
"I meant that it's more like a growth type grade, it grows stronger the stronger you get and depending on your own strength it can be the worst Star Rank 1 grade or even better than my Emperor Grade treasures." He replied.
"A growth type huh…" Kai muttered as he looked at the abyss like marvelous sword and completely mind-blowing overpowered core.
'So, basically the rank of these items doesn't have a limit and will keep rising the stronger I get! That's totally an end game item and super overpowered!!!" Kai exclaimed internally in his mind.
He then inwardly giggled a little and then turned to face the old man again. "Senior, can you tell me about cultivation stages and the other ranks too?" He asked curiously.
Old Man Hanxian smiled in response. 'No matter how talented he is, he is a child at the end!' He shook his head.
Then in a stern tone he spoke. "Listen well! This is basic knowledge you should never forget! The cultivation stages from weaker to stronger are respectively-"
Core Foundation Stage
Core Consolidation Stage
Ascendent Stage
Transcendent Stage
Heavenly King Stage
Heavenly Emperor Stage
"I was a Heavenly Emperor and remember kid even though it looks like there are very few of these realms the time, effort and talent required to break through only keeps increasing the higher you go."
"In this world only 1 Heavenly Emperor is born every era and that is also not assured as no one wants a foreign emperor to rule over them! You hear that! Only 1 out of the thousands of 9th Stage Heavenly King cultivators, you could imagine just how much of a challenge it is." He declared with his head slightly raised and chest protruding outward.
Kai listened like an attentive child listening to his teacher.
The old man then continued. "As for the grade rankings they are-"
Star Rank 1 - Star Rank 9
Mortal
Earth
Heaven
King
Emperor
"There are only a very few emperor grade items in the world and even mortal grade items are pretty rare! You will only commonly find star rank items." The Old Man said and then pointed towards the ring in Kai's hand.
"That's the only kind grade spacial ring of my time. So, make sure to keep it safe!" He said with a serious tone.
Kai merely smiled in response. He already had a way of storage thousands of times larger than the ring already.
They both started staring at each other in awkward silence.
"…"
"…"
*Sigh* 'This brat is so annoying! I can't believe I am giving my precious legacy to him.' Despite saying this there was a small smile evident on his face.
"Well kid, now that you have those amazing soul items, do you still want this old man's inheritance?" He questioned with a grin.
"Is that even a question? Senior is a 'Great Emperor' after all and used to rule over the world during his era, how could I miss this opportunity to become the richest in the world?" With a smile Kai replied.
"Merely senior, aren't you forgetting something important?" Kai asked as he glanced at a particular direction.
The old man raised an eyebrow.
"You still haven't told me about what Lilith is… what world spirits are." Kai said.
"Oh…, hahaha that was your very reason to take my trial at the start huh, how could I have forgotten?" The old man awkwardly laughed.
Lilith pouted and looked at the old man with an angered look which only made her look cuter.
She knew that the old man couldn't see her, but she still held her own grievances towards him for completely forgetting about her.
"A world spirit huh… those are equivalent to a myth even in this world. If not for an encounter I had with a certain someone even I would be completely oblivious about them." The old man said with a slightly angry voice.
*Sigh* He shook his head as he composed himself and continued. "World Spirit's are a noble race from another world that we don't know about. They can directly connect to the origin of any world and can even draw upon its power."
"In the Trial of Comprehension, the cultivation technique you comprehended was also related to the origin source. The origin source or in simpler words the core of the world can attract the world's mana towards it to strengthen itself and simultaneously it provides the world its mana to develop and improve it."
"Therefore, like we have mana core, world spirits have origin core's which helps them to absorb completely pure mana and use this pure form of mana called origin mana. Unlike the unpure mana that the other races use."
"What! Wouldn't that make them the strongest then?" Kai questioned.
Lilith nodded her head in agreement to Kai as she continued listening attentively. She is getting to know so much about herself that she had wanted to know about for years.
The old man faintly smiled as he continued. "Of course, nothing in the world is so good."
"For them to form this origin core they need the help of a person from another race, but there is a major problem... they can't leave their own world on their own."
"To leave and traverse between worlds they need to form a contract with the other party. Although the contents in the contract can be changed according to both parties, many take advantage of this and blackmail the world spirits into becoming their servants and such.
"And since the world spirits need to desperately form their origin core's they are left with no other choice than to obey these selfish demands."
"Who wouldn't want a powerful servant who can't retaliate against them?!" The old man explained.
Lilith had a complicated expression on her face while listening.
"How could they do something so disgusting?" Kai shouted with fury. 'What's with this inhumane treatment? Just because of a single fault they treat them like servants?'
Old Man Hanxian looked at Kai with a worried gaze. 'Looks like he is also a kindhearted person. *Sigh* The chances of him surviving till he reaches his peak are only growing dimmer.'
"Kid, the world is a cruel place. Only the strong have the right to speak while the weak could only obey and serve quietly. Even if you say it's disgusting its not like the world spirit race could do something about it, hence why they get taken advantage of." The old man said.
Kai grew quiet as he lowered his head and clenched his fist.
*Sigh* "By the way I thought about your friend's condition for a while and I think I have an idea of what it is."
Lilith's eyes glinted with a forgotten shine upon hearing this.
Kai quickly clasped his fists and bowed deeply. "Senior, please do tell."
