Apocalypse Summoner

Not my own i just want to share it!

...

He shall call forth the bone dragon! Summon the lich and the grim reaper! Li Jiayu, the dark summoner, has been reborn and everything returned to the moment before the outbreak of the devastating apocalypse.
Spaces tremble violently and dimensional cracks connected to various worlds appear! In an instant, never-seen-before civilizations invade our homeland. Insects the size of humans and walking corpses sweep through Earth in legions. An imminent crisis is approaching humanity and billions of human lives are at risk!
In regards to Li Jiayu's uncorrupted soul, his summons shall no longer be limited to creatures which lurk in the darkness. They will also include the entities that bask in the light.
Under the lingering shadow of death, he vows to prevent a repeat of past tragedies!
Struggling within the exhausting apocalyptic world, he chooses to trudge on the bloody path of slaughter.
