To upgrade the Pot Cave Heaven, one must first reach the upper limit of Spiritual Energy for the current level.
Then, after completing the upgrade task, the upgrade will successfully expand the actual usable area of the Grotto Heaven and add functionalities of buildings such as a blacksmith shop, a processing workshop, and a travel merchant shop.
[Pot Cave Heaven: Yunlai Immortal Realm]
[Current Level of Pot Cave Heaven: Level 1（0/100）]
"So, for the first level, I just need to get the Spiritual Energy output to 100, right?"
"Let's give it a try then."
Su Ping examined the specific requirements, thought for a moment, and took out two Building Cards he had obtained from drawing cards that could increase Spiritual Energy.
"Come forth, Evil Exorcism Punishment Stone Lion!"
With a rare quality, the stone lion that could slightly increase the Spiritual Qi of the Grotto Heaven appeared in mid-air with a swish as Su Ping used the card.
