The combination of the Soul King, Soul Reaper's power, and Menos' Reiatsu.
The creature gave off more of Menos' Reiatsu more than Soul Reaper's. After devouring the Spirit King's power, there have been significant changes in the overall structure.
Please forgive Tokikaze's limited knowledge, he can only discern up to this extent.
Upon devouring the remaining power of Mimihagi, the monstrous Menos before him underwent drastic transformation.
However, there was no doubt that it would have long ways to go if it wanted to evolve from Adjuchas to Vasto Lorde.
This Adjuchas was by no means a mutated species among the Menos.
Without any surprises, it should be artificially made creature that Aizen had modified or created through various means.
Although his Hogyoku was not completely perfected yet, with Aizen's intelligence, creating a Menos of Adjuchas level wasn't too difficult.
Upon sensing Tokikaze's Reiatsu, the Adjuchas abandoned the remaining ruins. Countless eyes all over its body firmly locked onto the figure standing in the wind.
Between a leftover and a sumptuous feast, even a fool would know which to choose.
Its slender tongue extended from the blood-filled mouth with sharp teeth, licking at the corners of its mouth, producing a creepy sound.
The Adjuchas shifted its center of gravity, and the foundation of the shrine cracked under its immense weight.
Just from looking at this colossal creature, most people would have trouble breathing.
And when its Reiatsu erupted, Tokikaze could feel that the atmosphere was heavier.
Above the sky, heavy dark clouds swept in again, covering the few remaining lights in this desolate land.
At this moment, the only light was the Adjuchas' red eyes.
It stared at Tokikaze with dripping saliva, which corroded the already messy shrine.
Seeing this, Tokikaze's eyelids twitched slightly, "He really added everything he could."
"Even his saliva is poisonous..."
Before he could finish his sentence, the colossal shadow instantly closed the distance with its red greedy gaze focusing on him.
It slammed Tokikaze down with his arm. It was quite powerful that the wind could be felt even before its arm hit Tokikaze!
Boom!
The ground was slammed down, forming a huge crater with the Adjuchas' fist at the center.
In terms of physical strength alone, Menos with Hierro alone was almost on par with an average Soul Reaper.
Tokikaze evaded using Shunpo, avoiding the attack by a hair's breadth.
Cold light flashed as his Zanpakuto was unsheathed!
Wind blades were immediately formed and headed straight for the Adjuchas.
Psskk!
The sound of flesh tearing broke the silence. Blood gushed out like a fountain, making the desolate land wet again.
While Tokikaze was leaping back, he did not forget to fire a Kido.
"Hado #63: Raikoho!"
Lightning condensed on his fingertip before he blasted it at the enemy!
Although Raikoho was only Hado #63, it packed quite a punch.
Combined with Tokikaze's Kido proficiency, he could increase the power of his incantation-less Raikoho to half of the one with full incantation if not more!
Boom!
A thunderous explosion echoed. The magnificent golden light soon engulfed the lower half of the Adjuchas's body, burning its spikes and the outer layer of bones with a terrifying heat.
In an instant, almost half of its steel skin was directly burned, and the inner flesh was incinerated at a speed visible to naked eye.
"Roar!"
A roar filled with anger and pain reverberated across the desolate land as the Adjuchas exerted all of its Reiatsu.
A massive trench of hundreds of meters was formed because of Tokikaze's Raikoho.
The moment black smoke dispersed, the battered figure of Adjuchas once again appeared in front of Tokikaze.
The conical body was nearly destroyed by almost half, and its right arm was cleanly cut off because of Raikoho.
This was just an experiment, and it ended with Adjuchas's complete defeat.
However, Tokikaze did not let his guard down because of this. Instead, he calmly watched the scene unfolding before him.
He knew deep down that a creature that Aizen made wouldn't be so fragile.
When dealing with Aizen, Tokikaze was always cautious.
Gulu—
The charred flesh kept squirming and rising, and white substance began to spread across the Adjuchas' body like bubbles.
Eyes sprouted from the bubbles, observing the surroundings with maniacal gazes. The eyeballs were filled with blood, adding a touch of eerie vibe to it.
The flesh of the Adjuchas' severed arm squirmed, and in an instant, its arm grew back!
"Die!"
The simple vocabulary this Adjuchas had indicated that it wasn't as smart as other Adjuchas, but its Reiatsu certainly far exceeded theirs.
A majestic Reiatsu towered into the sky, dispersing the clouds!
Such a terrifying Reiatsu naturally caught the attention of people like Captain Ukitake and others.
Even though they had already left Sakahone and were rushing towards the Seireitei at the fastest speed, some weak Ukitake Clan members instantly collapsed on the ground with despair in their eyes.
Matsumoto Rangiku also stopped on her tracks. She frowned out of concern as she looked back.
"This is the Reiatsu of a Menos. Captain..." she hesitated for a moment, then made a decisive order, "I'll go ahead and seek help from the Seireitei. You take care of these people, Nanao."
Without waiting for Nanao Ise's response, Matsumoto Rangiku burst out with a powerful Reiatsu and disappeared from the spot, heading straight for the Seireitei.
She was well aware that her own strength was far from enough in the face of such an overwhelming Reiatsu.
At this moment, she would just become a hindrance for Tokikaze if she came to his aid.
In such a situation, it was better to ask for reinforcements from the Seireitei as quickly as possible.
Moreover, Seireitei wouldn't overlook Reiatsu of this level of Reiatsu, right?
At the same time, in the Twelfth Division's Research and Development Institute.
Within the Spiritual Wave Measurement Research Department.
Red lights illuminated the entire laboratory, and the ear-splitting warning signals echoed, tormenting everyone's eardrums.
A bizarre creature resembling a humanoid toad sat in front of a computer as it typed various commands on the screen.
Its eyeballs were almost popping out, and an indescribable madness permeated its demeanor.
"Big News!"
"A Menos with nearly Vasto Lorde-level Reiatsu has appeared at Sakahone!"
