Everyone's a Land Ruler, Rolling Demon Soldier Types at the Start

Everyone landed on Boundless Land and became a land ruler participating in the Ten Thousand Races Conquest Tournament.
At the start of their arrival, each land ruler would receive a random starting Soldier-type Building.
Recruit soldiers, fend against enemies, plunder resources, build an empire, and conquer all ten thousand races!
Joe was surprised to discover that…
he had rolled the unique Soldier-type Building — Demon Transformation Blood Pool!
It could cultivate demons!
“Haha, mine is a high-tier Soldier-type Building, it can summon elves!”
“Mine is a top-tier Soldier-type Building, it can summon dragons to swarm the skies!”
“I can summon the Golden Behemoth, its strength sees no limits…...”
Seeing these gloating messages, Joe couldn’t help but sink into deep thought.
His demons are the dwellers of hell, a unique soldier-type.
Small Demon, Great Demon, Demon King, Demon Ruler, Demon Overlord, Demon God.
Even the weakest Small Demon was Sage Level!
The strongest was a terrifying Lord of the Gods Level being!
Everywhere the demon army went, there would be the silence of death!
