Chu Xisheng was taken aback when he heard this: "Wasn't it previously stated to be twenty days, or fifty thousand Demon Silver?"
"I remember incorrectly."
Ye Jingyuan stroked his white beard, his expression unchanged: "A Fourth Grade Secret Skill, how could it be that cheap?"
Even he couldn't resist the excitement, his curiosity unbearable.
If he couldn't figure out how Chu Xisheng had incorporated 'White Horse is Not a Horse' into his Sword Technique today, he wouldn't be able to meditate peacefully and cultivate Nourishing Essence Skill tonight.
Ye Jingyuan thought if this kid didn't write it down, he would raise the price to fifteen thousand Demon Silver, or sixty days of research access to the eighth floor of the Library.
Chu Xisheng's face darkened like iron; he could only pick up the pen and patiently begin writing.
