Actually, the efficiency has become astonishingly fast!
It only took Chen Mu seven or eight months from the moment he stepped into the Six Viscera Realm!
One must know that many martial artists in the Six Viscera Realm, after practicing for five or six years, may only achieve around seventy to eighty percent of the solidifying refinement level, and this level even preliminarily possesses the qualifications to assault the Mysterious Pass and attempt to step into the Marrow Cleansing Grandmaster Realm!
But for Chen Mu, he certainly would not stop there, let alone assault the Mysterious Pass with little chance of breaking through. Even if there was a chance to break through, he would not attempt it now because what seems to be an unattainable extreme tempering of the Six Viscera Realm for ordinary people, for him, if he had enough resources, he could easily achieve it.
