Ling Feng hurriedly asked, "So you know how to do it!"
"Not really, but at least a tiny bit better than you!"
Zhang He gave him a glance, his face full of helplessness.
"Fine, then I'll just observe and stealthily learn from you," Ling Feng said with a nonchalant smile.
Zhang He took a small portion of each of the dozen or so ingredients and placed them all into the alchemy furnace, then covered it with a lid.
After lighting the charcoal, he dusted off his hands and looked back at Ling Feng, "Now we just wait."
"That's it?"
Ling Feng's eyes were wide with disbelief.
"What else did you think alchemy involved?" Zhang He asked.
"Uh, it's hard to believe. Can elixirs really be created just like that? It sort of feels like a joke," Ling Feng still couldn't believe it.
Zhang He glared at him irritably, "Believe it or not, you'll see soon enough!"
Two grown men squatted on the ground, gazing at the alchemy furnace, silent for a long while.
