Because to hammer forge thirteen bones at the same time like he did, not only required a very strong spiritual power and great manipulation capability.
At the same time, the Qi Blood Power had to be extremely strong to condense thirteen Qi Blood hammers to forge the bones within one's body.
From this perspective alone, he knew his efficiency was nearly ten times that of a regular Martial Artist.
And moreover.
Condensing Qi Blood hammers to forge bones was also an extremely draining task, both spiritually and in terms of Qi Blood Power.

Would find it difficult to forge their bones many times in a day.
Yet this was not difficult for him.
Being in the water, he could quickly restore his own condition.
