Mortal Grandmaster

Every time a rune connected with another rune, they made a sound akin to a cord on a zither being struck. After a minute, 2 large runes formed in the air.

One read "Mortal" and the other read "Heaven"

Although nothing happened, Sheng Tian had memorized the process of which the runes had merged.

Intrigued, he waved his hands and started to piece together the advanced runes. However, he struggled more as most of the runes were unfamiliar, requiring trial and error.

It was as if he no longer cared about memorizing the runes, rather, Sheng Tian had forgotten about the matter, and instead focused on what was more interesting at hand.

Time passed slowly, and Sheng Tian's concentration never faltered.

An hour became 2, and hours became days.

3 days later...

Sheng Tian looked at the last rune and waved his hand. A wave of qi carried the rune into the last missing place. It fit in perfectly.

Weng!
