In the secret room, Xu Yan assumed a horse stance and began refining his bones.
As he circulated the formula, his blood and qi surged, his body warmed, and his blood and qi began to grow stronger.
The dragon of qi and blood wrapped around his bones appeared larger and its refining power while traversing his skeletal system became even stronger.
"As expected, the Red-eyed Tiger is the king among tigers, harboring immense qi and blood!"
Xu Yan channeled his qi and blood and started to temper them.
"The tempering speed has vastly increased!"
With the circulation of qi and blood, and continuous refinement, the copper bones started to show a faint glimmer of gold.
This was a sign of the transformation towards gold bones!
"Once the supplement made from simmering Red-eyed Tiger is ready, my bone refining speed will increase even more!"
"At this rate, I can complete the first transformation in five days at the latest!"
