Tower Defense World: My Territory Automatically Evolves

Liu Bai traveled through a different world and became a tower defense lord. Everyone in this world must choose a territory when they reach adulthood and build their own tower defense facilities to resist the overwhelming invasion of alien beasts from other worlds. Then stand firm, expand the territory, take in people to live in, become a lord, and become a master of this world. "This time travel has been sent, so let's do it." Liu Bai was assassinated and sent to the Hell-difficulty filthy land to face the endless sea of skeletons and undead. Just when he was about to make a move, he suddenly found that the defense tower in his territory was too good and would automatically upgrade. Your Arrow Tower is worried about your safety, automatically kills a thousand enemies, and is upgraded to a Sword Immortal Tower. Your supply tower thinks you are too poor, acquires a large amount of spiritual energy, and upgrades it to a fountain of life water. Your Soul-Calling Tower takes off and is upgraded to the Tomb of Ten Thousand Demons. Many years later, "Come to live in my territory? Don't you have any territory?"
