Zhang Yu instinctively said, "Because I resisted fiercely under extreme pressure, and ultimately broke through with Wang Yin's oppression at Level 1..."
Zhan Xian said, "This is indeed one reason, but is it possible... that there is also the relationship with 'Yu Shu'? Because of the existence of 'Yu Shu,' did you comprehend the hidden mysteries of the 'Residual Bull Sacrifice Technique'?"
"And was it also because of the existence of 'Yu Shu' that you perceived the connection between the 'Refining God Technique' and the 'Breaking Obsession and Casting Divine Technique'?"
Zhang Yu quietly looked at the 'Yu Shu' in front of him, as if recalling the scenes of practice that appeared in his mind every time his cultivation technique leveled up.
"Could it be... that 'Yu Shu' allowed me to gain insights beyond the contents of the manuals during the breakthrough?"
