Before, Teyvat didn't really have a mechanism like the Thunder Tribulation. At most, powerful Electro element lifeforms would sometimes draw in lightning to strengthen themselves.
But just as Ryan's alchemy differed from ordinary alchemy, the Thunder Tribulation he drew for his pills was also different from the natural lightning people knew.
— —!!!
As the tribulation lightning struck, the rampant lightning pierced through Osial's body, which was almost entirely composed of Hydro element, causing it to let out a pained roar towards the sky.
Under the rampant lightning, its divine power, which had not yet fully condensed, disintegrated, preventing it from launching an effective attack.
'Baal...'
The name of this God immediately came to Osial's mind after it was pierced by the tribulation lightning.
As one of the strongest Gods in the ocean, Liyue and Inazuma were like the two borders of its marine territory, so it had heard of Inazuma's God.
And this "Baal" was the most powerful Electro element God in its impression, said to be called the Raiden Shogun by mere humans.
During the thousand years it was sealed, did Inazuma's God and Liyue's God form an alliance...?
Thinking of this, such a thought arose in Osial's mind.
Subsequently, the continuous heavenly lightning piercing its body brought it back to its senses, accompanied by painful and angry roars echoing across the sea.
"H-how amazing! Is this also an Adeptus Art?"
Paimon said in shock, seeing Ryan and Ganyu summon heavenly lightning to attack Osial.
Keqing, beside them, also had a solemn expression.
Compared to this heavenly lightning, the Electro element power provided by her Vision seemed as insignificant as a glowworm under the bright moon.
However, Paimon's words made Cloud Retainer scratch her head.
Adepti could indeed summon wind and rain using Adeptus Arts, but heavenly lightning capable of harming a God already belonged to the clearance of the Electro Archon, one of the Seven Archons.
Wait... does this mean... my disciple Ryan has the potential of an Electro Archon!
Thinking of this, Cloud Retainer proudly raised her head again.
The Thunder Tribulation did not cease in the slightest due to the shock of the people on the Jade Chamber, striking Osial's body again and again.
Each clap of thunder was accompanied by flashing lightning. Paimon had to cover his eyes as he watched; the flashes were a bit blinding.
Under the Thunder Tribulation, Osial tried to dive directly into the sea, but painfully resurfaced due to the rampant electric currents.
It didn't know that the heavenly lightning was drawn by a small pill beside it, so it never left the range of the Thunder Tribulation.
After the long Thunder Tribulation, the dark clouds that had gathered in the sky due to the God's rage also dispersed.
Osial, covered in scars, had electric arcs constantly flickering on its body, and it looked incredibly weak. Blue blood, like viscous water, flowed into the sea from its wounds, which were split open by the electric currents.
"It seems to be over."
Seeing Osial in such a weakened state, Lumine no longer felt the previous pressure. She felt that now any Adeptus could easily seal it back.
"I think I probably know how to glaze pills in the future..."
Ryan muttered to himself, watching Osial endure the Thunder Tribulation for his pill.
As the Thunder Tribulation ended, the pill floating on the water finally completed its glazing. An ethereal colorful light emanated from the sea, like a rainbow, and at the same time, a medicinal fragrance wafted out.
The weakened Osial also seemed to catch the scent of the medicine. One of its less injured heads lowered, carefully observing the pill on the water.
"Oh no, my pill!"
Seeing this, Ryan exclaimed and quickly leaped down from the Jade Chamber.
"Ryan!"
"Eh? Child, don't be reckless!"
The Adepti on the Jade Chamber cried out in alarm, while Ryan, using Spirit Invocation, glided towards Osial with the help of Cloud Retainer.
But it was still too late. Osial opened its mouth and swallowed the pill from the sea.
Seeing this, Ryan naturally wouldn't continue to rush up and offer it more food; he could only hover in mid-air, heartbroken.
After swallowing the pill, Osial slowly shed its scarred body like a snake shedding its skin... In the end, only four giant snake heads without necks remained suspended in mid-air... One head had already been struck by the Thunder Tribulation and showed no signs of life, and the injuries on these four heads also remained.
After all, the One Head Two Arms Pill only simply puts a person into a one-head, two-arms state.
The next moment, four incredibly huge arms grew out from both sides of Osial's four heads.
Even though its heads looked like giant sea snakes, these four pairs of arms still resembled human arms, only their surfaces were covered in sea snake scales.
And unlike Yun Zuo Xu and Yun You Xu, who appeared when Ryan previously consumed the One Head Two Arms Pill, the arms that grew from Osial's heads were so massive they seemed capable of easily propping up Mt. Tianheng.
"..."
Osial's appearance after swallowing the pill left everyone on the Jade Chamber, both humans and Adepti, with slightly agape mouths.
This scene was something even Adepti who had lived for thousands of years had never seen... Fortunately, the One Head Two Arms Pill had no healing or strength-restoring effects, so Osial consuming it wasn't exactly aiding an enemy.
It was just that the mortals observing the battle from high places within Liyue Harbor might have nightmares.
Furthermore, even Osial's four heads were greatly shaken by its own appearance.
Already weakened, it momentarily felt a surge of retreat, powerless to resist the sealing force, and was pulled down into the sea, slowly disappearing.
The sea became quiet, but Osial's appearance just now was deeply imprinted in the hearts of everyone who saw it.
"Eh?"
At this moment, Ryan noticed something.
The seal beneath Guyun Stone Forest pulled back Osial's body, which had been shed after consuming the One Head Two Arms Pill, but it uniquely missed the detached head that no longer showed signs of life.
Ryan's eyes lit up, and he quickly flew towards that head.
"Awo!"
...With the help of the Adepti, Lumine and Paimon descended to the sea surface, stopping near Osial's head.
"Ryan, are you alright?"
Cloud Retainer landed and asked with concern.
"I'm fine, I just accidentally got shocked by the residual element power, but I wasn't injured."
On Osial's detached head, Ryan, who had reverted to his white fox form, looked up and explained to everyone.
"Speaking of which, Osial looked so scary just now, but now it actually left a head behind..."
Paimon looked at Osial's lifeless head and said with some surprise.
"In that case, residual God limbs might also give rise to resentment. How about we work together to seal it?"
After Paimon finished speaking, Mountain Shaper, among the Adepti nearby, suggested this.
However, no sooner had he spoken than Ryan, in his true form, instantly bristled, lowering his body and baring his teeth, instinctively letting out a few low growls.
"Ryan is... guarding his food!"
Seeing Ryan's reaction, Paimon's eyes widened in shock.
After Cloud Retainer raised his wing and patted Ryan's head, he finally quieted down.
But he firmly disagreed with sealing this head; such rare God-level material was hard to come by.
The Adepti couldn't argue with him, and since he was also a major contributor to repelling Osial, the Adepti could only warn him to be careful of any resentment that might arise from it.
And so, Osial's head fell into Ryan's hands. The qiankun bag's inner space was not difficult to fit a large head.
"I ate one of my pills, and I got one of its heads back. That's a fair trade, I suppose?"
Ryan, after putting away the head, glanced in the direction of Guyun Stone Forest and muttered...
