"Daily mana upkeep?" Jack said.
Their guild's mana cell was currently at level 3. It produced 30 mana every hour. The mana was used for various purposes. Mana was used for the construction and training of high-level units. Some advanced structures and units even had daily upkeep of mana. Members could donate mana cores to increase the mana, but because of Jeanny's divine treasure, mana core donation was no longer used to fill this mana cell. Hence, their need for guild mana was also urgent. Luckily, mana was considered a resource, so they also received mana from the two guild hostage tokens they possessed.
Finished with the exchange, Jack summoned the portal that took him back to the hut. When Jack was about to exit, Janus called him, "Mister Storm Wind, if I may have a minute of your time."
"Of course, you may. What can I help you with, Mister young Janus?" Jack replied with equal poise.
