In fact, immortals had far less stamina than Mo Qiong and the others had imagined.
Tai Su Qi was nothing like spiritual energy, which could be quickly refined into magic power.
It had to undergo a difficult refinement process before it could become immortal power.
That was why those in the heavens who remained in a Tai Su environment yet stayed at the Taiji Realm were called Qi Refiners.
Only those who had refined immortal power down to the atomic level, and who could remain eternally ageless and deathless as long as they had energy, were true immortals.
True immortals had a somewhat higher refinement efficiency, but they still could not rapidly digest Tai Su Qi.
Otherwise, with so much Tai Su Qi in the heavens, would it not have disappeared long ago? Why would they have needed to Seal the Heavens? Why not simply have all the immortals divide up the Tai Su Qi back then?
It was precisely because refinement was so difficult that so much ownerless Tai Su Qi still remained in the heavens.
For the same reason, an immortal's Tai Su immortal power could not recover while fighting.
Only spiritual energy was endlessly replenishing. Tai Su immortal power, however, grew less with every use.
Yet the high-energy shots Mo Qiong fired were no weaker than an immortal's attacks, and Julu had to use some Tai Su immortal power to dispel each one.
After fighting for more than ten minutes, he had consumed more than half of the Tai Su immortal power he had accumulated over the past three hundred years!
Boom! Julu struck the black armor again.
Swish! The black visor split open.
"Impressive... that strike of yours..." Mo Qiong said with difficulty.
"Shut up!" Julu roared furiously. Why wasn't this man dead yet?
No matter
