Just Out of the Furnace!

Three days later, in the refining room.

Over these three days and nights, Li Yao didn't sleep a wink. His eyes were almost blood-red, his hair was disheveled, and incoherent mumblings could be heard coming from his mouth.

A silver-white metal ring was wrapped around his forehead, engraved upon which were a few dozen freezing array glyphs. Whenever his body temperature shot higher than 40 degrees, it would automatically start operating, releasing a cold stream of air which would keep his brain temperature lower than 38 degrees.

"Whish! Whish!"

From the metal ring, a cold stream of air was constantly released, forming a faint layer of mist around Li Yao's forehead. It made him look almost like an extremely mysterious immortal.

Licking his dry lips, Li Yao inputted over a thousand blueprints and spiritual energy flow diagrams into the command crystal processor of the crafting furnace.
