Wood Beats Fire, Makes Sense, Right?

Liu Fei awakens an E-rank wood attribute, widely considered useless. Just as he's in despair, a bead falls from the sky and hits him on the head.

'This system has lived for three thousand years, and you're the first E-rank trash host.' Updates daily at a fixed time! — Description from novelcodex.org
