"Your Netherworld Divine Art has reached the tenth level, but to refine the Eternal Heavenly Coffin, you will need some time," said Master Ding's voice.
Yang Xiaotian was startled.
"The way you're refining it, it will take at least a year to refine that mass of evil force and the Eternal Heavenly Coffin!" Master Ding said.
Yang Xiaotian was dumbfounded.
A year?!
He surely couldn't just stay here for a year, doing nothing, not even cultivating, and then desperately try to overturn the Eternal Heavenly Coffin, right?
In a year, with diligent cultivation, he would have enough time to break through to the Saint Realm or even ascend to higher realms.
"Isn't there any other way?" asked Yang Xiaotian.
"Advance your Netherworld Divine Art to the eleventh level," Master Ding said.
Yang Xiaotian was speechless.
Even with the Death God Tree, it would take him years to cultivate the Netherworld Divine Art to the eleventh level.
That would take even longer.
