Unfortunately, Wu You's hopes were destined to be dashed. Qin Yu summoned a blackish rock from the Purple Micro Star Ring, along with a sword-shaped magic artifact obtained from the Shanyang Sect.
Qin Yu used the sword-shaped magic artifact to carve the blackish rock into the shape of a T-shaped tube. Soon, Qin Yu finished the carving.
Under the watchful eyes of the crowd, Qin Yu placed the T-shaped tube into the Earth Fire pipeline, then clapped his hands and said, "All done! Please, Uncle, open the Earth Fire Valve."
What? Everyone was stunned. That was it? Just putting in this blackish thing?
Though puzzled, Xiang Wentian did as Qin Yu had instructed and opened the Earth Fire valve!
Whoosh! Whoosh! A wave of heat hit them face-on! It was much hotter than before! The people hurriedly stepped back two paces!
Nangong Wudi stared intently; the flames beneath the alchemy furnace hadn't grown any larger than before, yet the heat they generated was much higher!
