Six and a half years ago, Zhang Fei visited that clan to upgrade his Demon Extermination Sword. He had long wanted to upgrade his sword, but they didn't have the Immortal Soul Crystal, and they said it would take at least ten years to find one. Since he already got one from the system, he decided to go see You Feng and You Jian again.
"Oh? What brings you here today?"
"Here." You Feng's and You Jian's expressions became ecstatic as soon as Zhang Fei took out the Immortal Soul Crystal. He summoned the Demon Extermination Sword out of his body and handed both items over to the two brothers. "You two already have the remaining materials, right?"
You Jian accepted the sword and the soul crystal. "We already got the remaining items long before you removed those gates, so we can start upgrading your sword today."
"How long will it take you guys to upgrade my sword?"
