"First, I'll go to Source Ruins Ancient City and exchange for a Dao-Tier Ninth-Grade Battle Mark!"
Lu Ren spoke calmly.
With that, he left Blackflame Territory and headed straight for Source Ruins Ancient City.
Source Ruins Ancient City.
It was the most unusual city on the second layer of the Ten Thousand Dao Source Ruins.
No territory controlled the city. Anyone could exchange Ten Thousand Dao Origin Crystals for cultivation resources there.
Dao pills, Great Dao Spirit Weapons, Dao-Tier Battle Marks—it had everything.
Lu Ren went straight to the trading house at the city's center.
"I want a Dao-Tier Ninth-Grade Battle Mark!"
Lu Ren got straight to the point.
At his words, the expressions of many cultivators in the trading house changed.
A Dao-Tier Ninth-Grade Battle Mark!
It was the best Battle Mark for inscribing the thirteenth mark.
Its price was a staggering one million Ten Thousand Dao Origin Crystals.
An ordinary Source-Integration Realm expert could never produce that many crystals.
The old man in charge of the trading house glanced at Lu Ren and said flatly, "A Dao-Tier Ninth-Grade Battle Mark costs one million Ten Thousand Dao Origin Crystals!"
Lu Ren waved his hand, sending a Storage Ring flying before the old man.
The old man probed the Storage Ring with his Divine Sense. After checking its contents, he accepted it and took out a jade box.
The box opened. A golden Battle Mark floated quietly inside.
The Battle Mark resembled a tiny golden Dao dragon. Nine halos faintly flowed across its surface, radiating immensely powerful fluctuations.
It was indeed a Dao-Tier Ninth-Grade Battle Mark.
The old man said, "This Battle Mark came from slaying a Battle Soul of the Ninefold Dao-Unification Realm. It has a very high chance of successfully inscribing the thirteenth mark, but success isn't guaranteed.
