Kapitel 409: Chapter 389 "Origin Spirit Sea", "Guardian", Step 5 "Shadow of the Demon

Supreme Rune.

It was a level higher than the spirit runes, containing the mysterious runes of enormous power!

Karl only saw the Supreme Rune within his own soul, the "Origin Spirit Sea" like a sea of water, continuously flashing with a subtle pale light. The surrounding runes encircled the Supreme Rune "Origin Spirit Sea" like a constellation around the moon.

They were all influenced by the Supreme Rune "Origin Spirit Sea," gaining a new characteristic "Burden Reduction"; the spiritual power needed for these runes to be used was about half of what was required before.

Before the appearance of the Supreme Rune "Origin Spirit Sea," all runes within Karl's soul were scattered, but after its manifestation, it seemed as if a ruler had suddenly appeared.

Karl couldn't help feeling pleased.

"It's indeed the power of the Supreme Rune, just this one impact has already returned most of the cost I invested into it."
