Beneath the manor, the cavern the Banshees had excavated had expanded several more times over. Its underground area was now even larger than the manor above.
And as the Banshees' Turn Stone to Mud technique developed—mainly thanks to Theus—he had successfully combined Turn Stone to Mud with steel reinforcement to create an otherworldly version of reinforced concrete. By all appearances, its strength was no lower than Blue Star's, perhaps even greater.
After all, stone melted by Turn Stone to Mud was less likely to leave voids when poured, and mistakes were exceptionally easy to correct.
Theus no longer had any motivation to make cement. This spell was simply too convenient. If not for the many things that would need to be built in the future, he would have wanted to let the Banshees work full-time in construction.
The Banshees were also enthusiastic about construction, especially when building their own home. They could even be called fanatical.
The feeling was very familiar to Theus. After thinking about it for a long time, he finally remembered—wasn't this exactly how he had been when playing Minecraft on his computer?
It was a building game where players could gather materials and construct buildings.
With Turn Stone to Mud, the difficulty of building and excavating for them really was not much different from the game...
As a result, quite a few Banshees spent all day immersed in digging holes, and the cavern beneath the manor continued to grow larger.
Theus thought about it. If it were him, Castel would sooner or later be hollowed out by his digging... It was just too fun!
Each Banshee had a somewhat different architectural style, but fortunately, adjustments were easy. A single Turn Stone to Mud would turn hard stone into putty that could be kneaded however one pleased.
