Chapter 228
And that's because Oliver was the [Circuit of Abyss], which meant he already had extremely well-defined abyssal channels in his body, like a complex and intricate circuit.
All the paths in his body were already mapped out like a blueprint, refined by the abyss, ready to be traced. So, all he had to do to create the espera channels was to follow those abyssal channels in his body and create adjacent espera channels.
This way, he was able to perfectly lay down the foundation of his espera channel and begin the path of a physical exorcist with a strong base.
Even the most experienced elders would have found it difficult to achieve such perfection in channel formation. After all, seniors could only assist externally; ultimately, a person had to be familiar with their own body internally.
This was also the reason why he was confident in attempting to create espera channels on his own without anyone's help.
