Heaven's Stealer Dismantler Manual {First Vol} (2)

Inside the secret underground chamber, Ace was sweating profusely, while his face was pale.

He did not know what was happening inside his knowledge sea, as his entire focus was on enduring the stabbing pain in his head. 

However, the moment that pentagon coin completely vanished inside Ace's dark knowledge sea, the pain suddenly vanished. 

Ace was bewildered by this abrupt change and with a bemused expression, he mumbled, "Strange, I got all this humongous information within minutes?" 

Thereupon, Ace's pale complexion slowly returned to his natural state, and he also stopped mulling over the strange thing that had just happened. 

Ace was now skimming through all the information of Heaven's Stealer Dismantler Manual's three principals. 

Just like that, hours passed and Ace was still engrossed in Heaven's Stealer Dismantler Manual with an impassive face while his eyes were tightly shut.
