"Take these. Your future lives in the Inner Academy will all depend on this unremarkable little card." Su Qian handed four green crystal cards to Xiao Jin and the others.
Xiao Jin took them all, then handed them out one by one to the other three girls.
Su Qian continued, "These are Fire Crystal Cards. See the number on them? That is the amount of Fire Energy you currently possess. If you want to enter the Inner Academy's Heaven Burning Qi Refining Tower to train, you must spend Fire Energy. Aside from that, buying items, exchanging for Qi Methods and Dou Techniques, and obtaining rare materials can all be done through Fire Energy transactions."
"Fire Crystal Cards are divided into five colors in total: black, blue, green, red, and purple. What you're holding now is the third-tier Green Fire Crystal Card. If you want to exchange it for a higher-grade Fire Crystal Card, you'll need to spend Fire Energy to do so."
Xiao Jin could not help asking, "If I have medicinal pills I want to sell to the academy, will the academy buy them?"
With Xun'er and Xiao Yi Xian's strength, a Green Crystal Card that only allowed them to train on the fifth or sixth floor of the Heaven Burning Qi Refining Tower was nowhere near enough.
They were already very close to becoming Dou Wangs. If they wanted to train through the Fallen Heart Flame, they would at least need to be on the bottommost level.
That would require the highest-grade purple Fire Crystal Card.
"You're an alchemist too?" Su Qian was somewhat surprised. Because of the delay in information, he only knew Xiao Jin was a Dou Wang, but did not know he was an alchemist.
Xiao Jin smiled and nodded, not saying much more.
