Abdin is an old cultivator that has six months left to live. People won't remember him just like they don't remember his dead sister. Abdin won't allow that to happen.
Luckily he is blessed with a unique power to summon castles. And most of his summons come with extra spirit ki that makes cultivation and cultivation breakthroughs trivial. His only problem is where to put his summons. A giant, majestic castle will need a big place to sit. If placed in the wrong place, a castle can easily expand and consume the nearby villages and cities.
Abdin is always meticulous about where to put his things. But you never know what happens with things made of mortar and black iron.
[It's now time to expand.]
[The castle has expanded and consumed three villages and two towns. A total of 63,345 lives are lost.]
[Next expansion will take place in three months. Do you want to continue or do you want to reset the expansion and start over from the beginning? Note that resetting the castle will reverse time to return all lives, villages, and towns to the way they used to be, but it will cost you years of lifespan and can lead to your demise.]
