After confirming that fighting cultivators at the Qi Refining Seventh Layer had little effect on purifying his spiritual power, Luo Chen stopped paying much attention to it.
For the next while, he basically stayed in the Pill Hall.
Pill refining, cultivation, reading, and digging tunnels.
Yes, digging tunnels!
After spending half a month, he forcibly dug through a tunnel leading to the Howling Moon Mountain Range.
For this, he ruined a Low-Grade Rank 1 Flying Sword and even raised the auxiliary Mountain Splitting Boulder Breaking Palm to Grandmaster Level.
And damn, the Grandmaster Level Mountain Splitting Boulder Breaking Palm was genuinely impressive.
With one palm strike, the spiritual power was dense and condensed.
Other than its rather short range of only ten zhang, it had almost no flaws.
The power of a single palm was nearly comparable to one strike from a High-Grade Magic Tool.
"No wonder Brother Wang's book was copied and resold so quickly after he put it up for sale."
"It truly has its merits!"
Luo Chen chuckled. Yet his joy did not stop there.
When cultivators normally fought, unless it was somewhere like the Dao Discussion Stage with its specially restricted environment, they usually kept a considerable distance from one another.
At a distance of ten zhang, it was difficult to hit anyone.
Whose Magic Tool could not casually fly a hundred meters or more to kill someone?
What pleased him was that this palm technique had provided him with four Achievement Points from beginning to end. Once it reached Great Perfection, it could provide one more Achievement Point.
With a soft laugh, Luo Chen lightly expelled spiritual power and shattered the final rock wall before him.
A refreshing nighttime mountain breeze poured in.
Luo Chen stepped out of the tunnel entrance and looked down below.
