Otherworld: Summon Heather at the Beginning

[Apocalypse Summoning Style, mainly based on the second game (including Genshin Impact: Collapse of Iron and Desolate Zone Zero) and anime]

Xie Yuhan traveled through time and space and became a dying scavenger, and was about to be devoured by wandering souls from the very beginning!

Little did they know that this was just the most insignificant appetizer of the end of the world!

In the moment of despair, the [Spirit Summoning System of Heroes from All Worlds] is activated!

While others are still contracting imps, my novice gift pack can directly summon the Sword Flag Lord Heatherin from "Starry Sky Railway"!

However, this is just the beginning!

What? The genius of the Ghost Control Association is still gloating over contracting a hundred-year-old vengeful spirit?

Sorry, my "Genshin Impact" Keqing, with one move of Tianjie Patrol, flattened the haunted department store!

My Geo Lord Zhongli, with one Sky Star shot, directly wiped out the D-level restricted area!

Saber's sworn holy sword, Nero's devilish right arm, the hail of bullets from the female wanderer...

Above the demons and gods, shadows called "Apostles" and "Gods" descend...

I will lead the heroic spirits of all realms and cut open the end of the world with one sword!
