Half a month later, Wu Ruo and Yu Lin, covered in dust, returned from Heavenly River Water Mansion.
In the Xinyou District, inside Lu Ku's residence.
"Yin Sha Dust," Wu Ruo handed a fist-sized clay jar to Lu Ku.
Yu Lin followed closely behind, his gray-white robe still stained with dots of black and red blood.
Clearly, spending a great deal of money to buy Yin Sha Dust had attracted some trouble.
"You two have worked hard," Lu Ku said solemnly.
Both nodded slightly and took their seats.
The other few also looked at the clay jar with delight in their eyes.
"Gongsun Sheng can only use the United Heart Rope to connect to one person at a time. His control over it is still very shallow."
"If we use only half of these Yin Sha Dust, the off-control target might just be achievable."
"The pain of bone-eroding heart-drilling in this cultivation is inevitable. But all we need to do is endure this period."
