If the Star Progeny Master were a farmer, the current situation would be akin to him diligently cultivating some crops, only to find that when it's time to harvest, the land has been seized by others and the crops have been safeguarded by them.
So, he set a fire outside the farm, intending to burn the crops down, but discovered that the fire had been repurposed by others to construct a fire wall, extinguishing his flames.
The Star Progeny Master's heart was filled with the anger and humiliation of having his harvest snatched away by dogs, and even upon returning home, he was unable to shake off the bitterness.
He forcefully slashed open the Void before him, and with the opening of a massive rift, an intense red light seeped through. Gazing into the fissure, the entire field of vision was filled by an immense fireball, which turned out to be the sphere-like space used to cultivate Mourning Undead Soldiers.
