Global Slaughter: From the Start, I Summon Billions of Skeleton Soldiers

One hundred billion people from Blue Star descend into otherworldly realms across the heavens. The people of countries such as Huaxia, Japan, and the Lighthouse Nation fight and kill to survive. Xiao Xing, who transmigrated here, obtains the unique skill [Skeleton Summoning] the moment he enters these realms. An army of hundreds of millions of skeletons surges across the realms like a tide, devouring every enemy. One hundred thousand skeletons unlock Skeleton Swordsmen. One million skeletons unlock Skeleton Titans, who devour everything. Ten million skeletons unlock Skeleton Bone Dragons, who subdue all things. There is nothing in the world that a million skeletons can't handle... And if there is, just add another million!
