In God's Domain, players could gain attributes by leveling up, but permanently increasing their attributes through other means was extremely difficult. Every such treasure was worth a fortune.
Losing 400 HP at once meant losing 20 Endurance points—a significant weakening for any player.
Even someone with attributes like Shi Feng's would feel the sting, let alone anyone else.
Now that he had seen the true nature of the Power of Evolution, Shi Feng still gritted his teeth and chose to sacrifice 400 HP.
Although 400 HP was precious, it was nothing compared to advancing the Heart of Icarus to an Epic item. Besides, Shi Feng knew several ways to permanently increase Endurance, so he could fully make up for the lost attribute points.
The moment Shi Feng clicked agree, the Holy Grail's divine power surged.
Threads of emerald starlight emerged from Shi Feng's body and flowed into the Holy Grail. After absorbing 400 of Shi Feng's HP, the Holy Grail shot a strand of purple radiance onto the Heart of Icarus.
At once, the Heart of Icarus gave off a dazzling golden glow, forcing Shi Feng to close his eyes.
Once the golden light faded, Shi Feng opened his eyes and looked at the Heart of Icarus again. He found that it had changed noticeably—the halo it emitted had turned light purple.
"Did it succeed?" Shi Feng nervously checked the Heart of Icarus's attributes.
If it had failed, he would not only have permanently lost 400 HP, but would also have to wait another ten days before making another sacrifice.
However, when he saw the Heart of Icarus's attributes, even the normally composed Shi Feng could not help clenching his fists in overwhelming excitement.
It had succeeded!
