One had to remember that Aksai had sent a clone in the 2nd world he had unlocked for himself.
This clone kept on growing on his own with minimal interference from Aksai.
Although he was still yet to become a powerhouse by Acarnis' standards, Aksai's clone had already steadied his position in his world.
Reaching out with his mind, Aksai connected with his clone, Aron, who resided in the Aether World of Acarnis.
Using their soul-based telepathy, Aksai asked Aron to lend him some of his powers.
Thankfully, Aron wasn't busy with his work in the RAD department, where schedules were relaxed and flexible.
Without hesitation, Aron settled into a meditative position, closed his eyes, and began channeling his advanced Aether Cultivation powers. Through their shared Soul Resonance, Aksai felt a surge of energy flood his soul, which was then manifested around his body.
