As for the tribulation alchemy, he took the idea from the heavenly pill tribulation when eighth- and ninth-rank pills are created. The successful pill tribulation removes the impurity and condenses the pill and improves its potency and grants it spirituality, which is some kind of reward from heaven.
Shen Yi used the same pill tribulation principle and created an artificial tribulation using his hybrid lightning aspects in gathering the medicine liquid, then fusing and condensing them in a specific ratio, all with his lightning tribulation. Each pill from rank one to five requires specific lightning intensity.
Despite having heaven-level soul power, it took him a while to find the specific lightning intensity required for different types of pills; still, the research on pills above fifth rank remains, and he has yet to explore the lightning intensity required for those pills.
…
A few more months passed,
It's been a year since Shen Yi joined the Jia Nan Academy.
Back mountain,
"Nine Heavenly Chains!!!"
A heavy rumbling sound spread, mixed with a metal clanging sound.
Boom! Boom!! Boom!!!
Immediately nine purple lightning bolts flashed through the forest as if lightning were tearing through the cloud, and countless trees and stones burst.
Nine heavy purple chains spread around with golden metallic shine and bound everything around. Whether they were trees, vines, or stones, everything was suppressed and scorched with intense lightning.
All these nine purple chains are connected to the figure clad in pure purple lightning as if a dense lightning armor is condensed on his physique.
Meanwhile, another figure of a beautiful young female, about sixteen or seventeen years old, was looking at him brightly with her purple pupils.
She is Zi Yan, whose height increased and whose appearance aged after unlocking her bloodline to seventy percent using the treasure provided by Shen Yi in the past few months.
'This lightning chain looks extremely dangerous; even Dou Huang may not escape their clutches.'
She thought to herself while looking at Shen Yi, spirituality flashed through her pupils, different from her previous ignorance; there is also nobility and arrogance in her demeanor, but while looking at him, all her coldness melts away as if ice in front of the sun.
Shen Yi retracted his dou qi, and the lightning chains dissipated around him.
'With my current disguised nine-star dou spirit strength, this technique can even bind a dou king and dou huang if careless. But if I use my actual nine-star dou ancestor strength, then this may even bind the three- or four-star dou venerate expert. Now it is a proper top earth-class exercise, just a thread away from heaven level.'
Shen Yi nodded satisfied after testing his upgraded nine heavenly chains technique.
In the past few months, he enhanced his chain technique and also his tribulation alchemy; now he can concoct seventh-level pills easily. That's why his strength increased by leaps and bounds in just a few months and reached the nine-star dou ancestor.
"Brother Shen Yi, I have found the sixth-rank medicine you asked me to look for."
Immediately Zi Yan's voice sounded in his mind, and her beautiful figure appeared, landing beside him. She raised her hand, showing the sixth-rank medicine plant.
Shen Yi glanced at the plant in her hand and then smiled, looking at the grown-up Zi Yan. She became more beautiful, and her appearance started revealing distinctive features of dragons, like pointy ears and purple pupils, her appearance now almost rivaling the Medusa of the snake clan. It's just that Medusa has more mature charm than her, which attracts more eyes.
He nodded and took the medicinal herb from her and said, looking at it, "Today I will concoct the eighth-rank pill for you; it will promote and unlock your bloodline to eighty percent, then we will proceed to the next plan."
Immediately the Zi Yan pupils lit up, and she spoke, "Next plan, which means you will tell me about my father's location."
She became extremely excited as she waited for this moment in anticipation each passing day.
While her bloodline was unlocked, she learned a lot of mysteries about her origin automatically, like that she possesses the most terrifying bloodline on the continent, the most powerful Taixu Ancient Void Dragon.
But she didn't know about her father's location, as no one knows beside Shen Yi in the whole continent, and she waited for this day. Finally it's the moment where her patience is going to pay off.
She thought of something and fell silent, looking at Shen Yi.
'What will he gain after helping me so much? It seems he will definitely demand something from my father, as he told me that my father is one of the strongest beings on this continent.'
She felt her guess was right, and a strange kind of loss surged through her heart, and then she hurriedly shook her head.
Shen Yi glanced at her weird actions speechlessly and then, not caring, turned around and walked toward the stone.
'It seems this year freshmen must have arrived in the outer branch; probably Xiao Xun'er also arrived as the new recruit. Previously, Han Yue was the number one peerless beauty in the inner branch; now it's Zi Yan. I wonder if Xiao Xun'er will take her place or not.'
Shen Yi thought to himself and then shook his head. He didn't care who got the number one beauty title; it was just a curious thought.
"Zi Yan, don't let anyone disturb me; there will be heavenly tribulation later, as I am going to concoct the eighth-grade pill. You must stop the elders who want to investigate; tell them that I am practicing a dangerous technique that requires the heaven tribulation… Don't let them know my secrets at all costs, or it will affect our plan."
Shen Yi instructed, looking at her calmly, and then sat down cross-legged on the stone, releasing the eighty-eight different kinds of herbs he got in these months.
Zi Yan nodded, and then her expression became cold as her figure blurred and merged with the void.
In the past few months while unlocking her bloodline, her strength also reached the top tier 6 rank, almost rivaling top dou emperor experts among humans, but because of her bloodline, she can control and use space abilities better than dou ancestor and low-level dou venerate experts.
The whole academy was shocked and curious about her sudden change, but no one found the reason except some elders. Even elders only know that Shen Yi is the true reason behind her achievements, but they don't know how he did it.
