After swimming for a minute, Yuan immediately gave up on trying to swim normally and propelled himself forward using spiritual energy.
Not only did this help him travel many times faster but it also protected him from the cold. However, because every drop of water in the Sword Pond is covered in Sword Aura, it would shred his spiritual energy constantly.
Fortunately, he could recover his spiritual energy faster than the Sword Aura destroyed it.
About a hundred miles down, the temperature in the Sword Pond changed drastically.
It was no longer cold, but scorching hot, almost as though he was swimming in lava, and it burned through his spiritual energy like a hot knife in butter.
This sudden change in temperatures caught Yuan off guard, and he had to quickly adjust to it.
The temperature was so hot that it constantly burned his skin. If it weren't for his regeneration ability, he would definitely die if he continued diving deeper.
Yuan endured the burning sensation that consumed his entire body and continued moving forward, swimming deeper and deeper into the Sword Pond.
Two hundred miles deep, the temperature changed again, returning to being extremely cold, but it was at least two times colder than before.
This same pattern continued until he reached a depth of 500 miles.
'What is this sensation? It feels cold and hot at the same time.'
Yuan was baffled by this phenomenon that he could not fully describe. His skin felt like it was being burned, yet it also felt like he was cold. It was a weird feeling that he has never experienced before.
However, even more horrifying was the fact that his regeneration ability was barely keeping up with the destruction done to his body, which was a first as well.
'If I continue diving deeper without any plans, I will definitely not make it to the end and die.'
He stopped moving temporarily to ponder a solution.
A moment later, he recalled something that he'd done in one of his previous lives.
'To temper the body is to embark on a journey of destruction and rebirth, tearing down the old and rebuilding the new, like a phoenix rising from the ashes…'
'Ahh… I understand what I have to do… This Sword Pond… It's the perfect environment to temper my body…'
And for the next week, Yuan would remain at the 500 miles mark without moving an inch, letting the hot and cold water continuously destroy his body.
Ding!
<Your skill 'Perfect Regeneration' has reached its maximum potential>
With his improved Perfect Regeneration, Yuan's body was regenerating at a much faster pace than previously.
'Perfect. Now I can continue.' Yuan smiled inwardly as he began moving again.
For the next 500 miles, Yuan would experience even harsher temperature conditions, which made him wonder if there was a limit to it.
