When Mountain Breaking is executed to the extreme, even an ordinary person can send three people flying with a single punch. However, the aftermath one has to endure is unimaginable, as it almost drains all of one's energy.
For a martial artist, most can control their strength, so it's generally fine.
But Mountain Breaking is not something ordinary people can train in. When Fang Yi was learning this move from the old man, he was warned that unless he was absolutely sure, he shouldn't use Mountain Breaking recklessly.
Especially emptying all one's energy recklessly, because once used, there's no way out, just waiting for death.
However, Fang Yi had the Seven Turns of Domination on his side, and he was only unable to use inner strength and true qi, thus he was still of Heavenly Level. Now, with the third turn of the Seven Turns of Domination, Fang Yi's strength rose directly to the second rank of Heavenly Level.
It's enough!
