บท 3808: Refinable Metal Synthesis

Feng Wu asked in a serious tone, "Will a copy of 'Refinable Metal Synthesis' be enough to exchange for the metal I just made and the drawing of this arm?"

Of course! Huyan Yichen was so excited that he almost burst into tears.

"But… but how can you have it?" Huyan Yichen wouldn't believe it.

Feng Wu said, "I just do."

Huyan Yichen said, "If you have it, I'll trade with you!"

Feng Wu said, "It's a deal."

Huyan Yichen was thrilled.

"Grandpa! Grandpa!"
