Back in the Wu Clan, Tian Xuan is teaching the Yi Sibling in his room while Li Yiyuan is guiding the sect students as well as the slaves the way of cultivation. Earlier before the other started teaching, Wu Xian already gave simple guideline in sword art to Yi Ling, Wu Yunfeng, and Wu Linyi before he stayed in his old courtyard.
For inner sect student and above, Tian Xuan gave cultivation manual of saint or heavenly tier while he bought ten basic manuals for each tier from tier 1 to tier 9 for the outer sect students. He also gave another tier-3 bag filled with only low tier spiritual stones to Li Yiyuan for the students.
The ten basic manual consist of an element in each manual which would be pure Yin, pure Yang, earth, fire, water, wind, holy, darkness, sound, and metal.
Although Tian Xuan could have bought Saint Tier for everyone, he doesn't have so much time to guide everyone in cultivation. Higher tier doesn't necessarily mean better for everyone. Even for someone like Li Yiyuan could not understand heavenly tier graded cultivation manual if not for Tian Xuan guiding him in the cultivation.
The higher tier would mean the higher level understanding a person must have to be able to cultivate the technique in a correct method.
Therefore, even if one able to catch hold on a godly tier book they could not use it if they don't understand a higher tier book. They rather keep it as family heritage or sell it for wealth than forcefully try to understand it while neglecting their own cultivation.
Sure it is faster to cultivate with higher tier technique but without someone that has the higher level understanding to guide the person in cultivation, the cultivator might cultivate the wrong way and ended up destroying his own cultivation.
Even if cultivating with lower tier technique is slow, with the spiritual stone to be absorbed, the gap between talented and non-talented cultivator won't be too large.
In fact, if one is diligent, the non-talented cultivator can surpass the talented people.
In the hall, Li Yiyuan let the students pick the book that matched their cultivation core.
There are a few that choose middle tier but the rest of them chose low tier manuals and choose the same book which is to be expected because they are not as a genius like Wu Yunfeng or talented like Wu Linyi.
[Low tier 1-3 tier; Middle tier 4-6 tier; High tier 7-9 tier; Higher tier Ancient-Heavenly; Highest Tier Godly-Elysian]
Only talented people can understand high tier technique and genius can understand technique higher tier which was ancient and heavenly.
The godly tier can be understood only by the so-called one in thousand year genius and Elysian Tier can be understood only by one in million year genius. Or so that's how it should be but with the extremely useful system by his side, Tian Xuan doesn't have to worry about anything.
The only problem for Tian Xuan, in the system shop, he could not unlock any tier above heavenly tier. The only Godly tier he has was the cultivation manual he got from the universe. Tian Qiu said he needs to level up to advance system to unlock Godly tier but as for Elysian Tier, it is just impossible.
In the whole world, there can only be one Elysian tier for a type of item. If it is a weapon like a sword, there will be only one sword in the whole world to be recognized as an Elysian tier.
Li Yiyuan patiently guided the student after they chose the technique. For low to high tier, he will not have so much trouble to comprehend the cultivation technique but for the higher tier, he will need Tian Qiu or Tian Xuan to help him.
Even if the student chose the same one, they won't fight over a manual because the cultivation technique can be shared. However, it will create a small competition spirit among those that choose the same cultivation technique.
One of the students trembled as he received a low tier spiritual stone from the teacher Yiyuan. "Yuan Shi, is… is this re-really for us to use?"
[Yuan Shi is a nickname for teacher Yiyuan. Shi is a short form of shifu.]
Li Yiyuan curled his lips upward and smiled cordially.
"If you finished absorb it, you can ask for more." He relayed Tian Xuan's message to the students.
The students felt like their world is turning upside down especially for those that have experienced becoming an inner student in a sect. The slaves knew the existence of the spiritual stone but to them, it is the same as gold.
As long as one is rich, they will be able to have one so they aren't too shocked when receiving the white jade brimmed with energy in their hand.
Li Yiyuan clapped his hand and awakened those students that frozen in time.
"Alright, come on. Even if the Lord says that we relax for two days, as your teacher I still need to see improvement in your cultivation!"
"Yes!" The students shouted and sat down in lotus pose.
At the other side, without saying anything further, the Yi sibling walked and sat with a serious expression on their face in front of Tian Xuan.
Tian Xuan smiled in satisfaction as he took out the book that Tian Qiu bought from the shop.
[First Chapter of Hollow Redemption Cultivation Technique] [Saint Tier|70 low tier spiritual stone]
Yi Ling has a solid foundation in her body. She has the ability to absorb all sort of emotion and has a perfect control over them. She doesn't cultivate normally like other people. She used pain to aids in her cultivation which is why she purposely let people wound her all over her body from her face to her leg.
It was the same method as the art of Seven Anguish lost Cultivation Technique, a godly tier cultivation technique. This cultivation technique is also the reason why Yi Ling able to wield such a huge weapon as if it is a common broadsword.
Aside from Tian Xuan that have Primordial Demonic Qi Gathering a godly tier cultivation manual that he received from the universal, only Yi Ling has the luck to cultivate this technique.
Of course, she unconsciously cultivated using a technique without knowing that it is an existed technique.
To forcefully changes her cultivation technique will perturb her solid foundation so Tian Qiu bought the Hollow Redemption Cultivation manual so that it could harmonize with Seven Anguish cultivation technique while double the power.
To unlock a godly tier item, Tian Xuan had to pay 1 Soul jade or 100 high tier spiritual stones and then, he will be penalized with one day to be unable to open his inventory or the shop. Which might not seem so heavy penalized but in a desperate situation, it will be dangerous for Tian Xuan to not be able to open the shop or his inventory where he always keeps his items.
First, he kept all the items that he stored in the inventory to the small world or his spatial ring.
Afterward, Tian Xuan bought the manual of Seven Anguish cultivation technique which cost 100 high tier spiritual stones and additional 100 high tier spiritual stones to unlock the item. It is bloody expensive but for someone who already chose the manual to cultivate, it will be more wasteful not to master it.
He touched the manual cover and absorbed all the information in it.
The reason it is called lost cultivation technique is that it needs other cultivation technique to aid in so that it could be complete and shows more effectiveness in cultivation.
He doesn't delay even a second.
After he understood the contents, he immediately taught Yi Ling the method to cultivate.
Since it is only the first chapter of the Hollow Redemption cultivation technique, all Yi Ling has to do is absorb the surrounding qi without being limited as if she is a black hole that keeps absorbing everything and impossible for the qi to leave her body through the method he taught Yi Ling.
She absorbed the surrounding qi boundlessly but the qi is not enough for her. Tian Xuan told her to take out the spiritual stones to be absorbed.
Only when he thinks that she has absorbed enough, Tian Xuan going to properly teaches her the art of Seven Anguish.
Yi Zhao couldn't feel the spiritual fluctuation no matter how much he watched his sister so Tian Xuan helped him first. He opened the boy's meridian forcefully and inserted his zhenqi to help the boy feel it.
The boy jolted as he felt his body being torn apart but it soothed quickly when Tian Xuan poured his zhenqi into the body.
After Yi Zhao familiarized himself with the energy, he started absorbing the surroundings energy around him on his own.
The process will take quite some time so Tian Xuan called Wu clan servant to watch after the boy.
In the meantime, he brought Yi Ling to the mountain where Wu Xian used to cultivate at and search for a waterfall.
