Bang!
The metal door shut with an airtight seal.
All the noise was instantly cut off outside, the soundproofing unbelievably effective.
In the dim environment, only multicolored lights flickered across the walls—sealing arrays carrying mysterious power.
"According to Federation textbooks, now that I've advanced to the fifth rank, the success rate is above 99%!"
Seville took a deep breath and began setting up the ritual.
Once everything was ready, he opened the potion bottle and allowed the slightly illusory liquid to turn into mist, which seeped into his body in wisps.
"Ah!"
The next moment, terrifying pain struck him.
Even though he had undergone specialized training and targeted practice beforehand, Seville still let out a muffled groan.
Large patches of darkness emerged across his body, and he suddenly became blurred.
Indescribable sounds came from the void.
They were maddening whispers carrying unnamable information.
Advancing as a Void Demon Spirit was considered extremely difficult even among the many saint paths. It was the price that had to be paid to gain the power of the void.
"Endure it. Ignore these disturbances!"
"Perform Meditation No. 3. Use your mind to regulate your body."
"I will definitely become a fifth-rank warrior!"
Seville's gaze was firm as his body continuously changed.
After an unknown amount of time had passed, all the pain and whispers abruptly faded away.
Seville rose to his feet and found that his body had undergone a certain degree of transformation. Silver light shone from his pupils.
With a mere thought, his body even showed signs of turning to mist.
"I succeeded!"
He did not cheer. Instead, as though he had merely completed an ordinary task, he sat cross-legged and recovered his spent strength and mental energy.
Half an hour later, the door opened from within.
"Congratulations."
A faint smile
