War Hymn of Prehistoric Times

In the Lich War, are both sides really losing? Why did millions of Lich soldiers suddenly disappear after the war? Where are they all going? Wen Zifeng, a little earthling, traveled to the ancient times, where would he go? Is it singing all the way, killing gods and demons, or is it a "gou" way to carry it out from beginning to end? I can't edit anymore. I'm a newbie. I'm just writing indiscriminately. There's no outline. Just one word: Just do whatever you want. Write when you want to, forget about it if you don't want to. This novel and its characters are purely fictitious. Any similarity is purely coincidental and should not be imitated.
