Caizher searched and searched for the things he has whether it be information or items. He did it for a short period of time but for him, it felt like years
When Caizher almost loses hope his mind locked on the thing he currently doesn't how to use. It was the only thing that is beyond his understanding
It was the ..... red lightning he got from the heavens when he almost died. He got it when he was still in the underworld. He clearly remembered how he almost died from that lightning
If Caizher wasn't able to touch the crystal that contained one of the beings in the universe that tried to reach Godhood, he won't even survive into this day
At that time, Caizher just put this lightning inside his spirit sea without giving it much thinking. He just thought that one day, it might be useful for him
