Xu Fan left the underground space satisfied and returned to his small courtyard.
A sudden idea popped into his mind. Since using the Mysterious Yellow Qi could improve the realm of an Artifact Refining Grandmaster, then maybe he could consume the Mysterious Yellow Qi to temporarily boost himself to the Golden Immortal Realm.
Although controlling a Golden Immortal Puppet could grant him combat power far exceeding that of an average Golden Immortal, how could this power compare to actually attaining the Golden Immortal realm for his main body?
"Pu Tao, can I use the Mysterious Yellow Qi to temporarily boost myself to the Golden Immortal realm?" Xu Fan asked.
"Master, when I was studying the Mysterious Yellow Qi, I had already thought about this possibility. But the consumption is too enormous and I wouldn't recommend using it in actual battles in non-essential situations." Pu Tao replied.
"How big is the consumption?"
