Ren Suo had discovered the "Equipment Interface" containing "Mysterious Sovereign's Secret Records (Chapter One)" early on.
Unlike the "Advanced Cultivation Method", the Secret Records seemed to be recognized by the game console as a 'special ability'. However, after equipping it, Ren Suo realized that it was quite similar to his own cultivation.
There was a gap, simply put, Ren Suo's own efficiency in cultivating the Secret Records was about 60%~70%, but after equipping it, he could achieve 100% effectiveness.
Yet, Ren Suo could enhance his proficiency with the Secret Records by continually cultivating it, so naturally, he would not take this shortcut. In the long term, Ren Suo could at least master one Cultivation Technique; from a short-term perspective, Ren Suo could free up a slot to equip another skill.
