บท 287: Opening the locked door!

Ace took the fifth insight pill and start learning the Lock Eraser King Technique's first-level, Lock Eraser Master! 

This time, it took him over six hours to achieve the first novice lair of Lock Eraser Master level!

Ace felt quite glad that he used an insight pill because if he tried to learn it normally it would take him at least an entire month, minimum. It was just damn profound!   

Nevertheless, he can now easily erase any array, formation, or even a talisman lock as long as they were Grade One or lower. This technique was truly marvelous and far more powerful than his treasure-opening hands. 

It is just that it can only be used on lock-type rune symbols and not took advantage of flaws like treasure opening hands, and it was a clear disadvantage.
