That exclusive skill was Demon Hunting Mark.
Long ago, not long after his rebirth, when Qin Feng was fighting the Diamond Tier Nightmare Hellflower outside the Magic City Ruins, he had factored in Demon Hunting Mark's damage boost to kill that Diamond Tier boss.
The most basic version of Demon Hunting Mark only increased the damage demons took by 15%.
But Qin Feng used Blessing Judgment to raise it straight to Epic Grade!
This cost a full 140,000 points of divinity, equivalent to 700,000 years of lifespan, and enhanced Demon Hunting Mark's effect to increase the damage demons took by 125%!
Of course, Qin Feng benefited from upgrading this skill too...
Using God-Stealing Hand, Qin Feng stole the skill for himself.
It became a skill he could use too!
From now on, he could put Demon Hunting Mark on a boss before fighting it, more than doubling his damage again!
Before unlocking Blessing Judgment, a 15% damage boost had held little appeal for Qin Feng, but after he unlocked it...
A 125% damage increase against demons was an entirely different matter!
Of course!
Blessing Judgment had a cooldown when used on the same target.
So, for Late Night, Light Rain, Qin Feng prioritized upgrading her Demon Hunting Mark, since he could only upgrade it for her through Blessing Judgment.
Only afterward did he upgrade her talent, using tradable Talent Seeds.
Qin Feng gave her ten thousand Talent Seeds outright. She quickly used over eight thousand of them before her talent rose by two grades...
For this, Qin Feng charged her only a little over eight million years of lifespan.
Late Night, Light Rain understood perfectly well too.
The value of these things simply could not be measured in lifespan!
A little over eight million was already a friends' rate-or even
