"Is that so?"
Zhou Taiping looked at Xie Chenkun skeptically. "But the amount of True Yuan from an Earth Level Lower Grade Technique shouldn't be enough to sustain for this long, right?"
Others might have been easily misguided by Xie Chenkun's words.
But this "Sword Mountain Fiery Sea" is the Illusory Realm Treasure of their Blood Sword Sect. They had long since studied it and knew exactly what kind of performance to expect from different levels of strength entering it.
Even the unparalleled Dao Wuming barely managed to pass two levels of Sword Mountain not long ago; as soon as he entered the Sea of Fire, he immediately died!
After his recent breakthrough, he could only barely sustain in the Sea of Fire for a while, unable to pass even the first level of the Sea of Fire!
So, Zhou Taiping was extremely skeptical about Xie Chenkun's claim that Mu Jinyu had cultivated an Earth Level Lower Grade Technique and thus passed the first level of the Sea of Fire!
