After Lu Changsheng left the Great Dream Immortal City, the Michen Banner appeared in his hand.
"Boom!"
Might akin to a river breaching its banks poured into the Michen Banner.
But the Artifact Spirit informed Lu Changsheng that this level of mana was far from enough to teleport back to Bi Lake Mountain.
"Since that's the case, let's just spend some more!"
Even though rushing back with all his might would only take about ten days.
Yet Lu Changsheng also wanted to test out the true effects of the Michen Banner!
"Boom!"
The hundred thousand Spirit Stones previously injected into the Mount Sumeru Mustard Seed Space of the Michen Banner frantically combusted.
However, even with all these Spirit Stones burning, it was still insufficient.
Lu Changsheng injected another hundred thousand Spirit Stones, and only then did the Michen Banner emit a brilliant five-colored light, transforming into a colorful cloud that enveloped him, creating undulating ripples like water waves.
