As such, being able to stand on the lava lake was a simple thing for him. The heat of the Lava was higher than normal lava that would be found in mortal worlds though, with most things burning and melting in it, if they were not strong enough to endure it.

Even the immortal Qi fluctuation coming from it were different and were not just pure Immortal Qi fluctuations.
'Its a mix of different types of immortal Qis… it's definitely not something common.' Lady Kang thought to herself.
