While thinking about upgrading the Hero Altar to the highest level and summoning four Beastman Heroes.
But I found out that the altar's level is limited by the main city's level, meaning a level three main city can only summon one hero.
Unless the main city is upgraded, there's no way to continue summoning.
After the main city reaches level three, the resource quantity needed for the next level increases exponentially.
Originally, it only cost a few thousand resources; now, it's tens of thousands at every turn, no wonder Tang Xichen's level four main city is so impressive.
Keep in mind Rosen already controls five gold mines, and Sister Tang's situation probably isn't too bad either.
With his current resource gathering speed, he can upgrade the main city to level four within two days and by the way increase the hero altar by one level.
Then summon two heroes.
Rosen now can only summon the Prophet first.
