Until Death do us Part

Two spherical objects of palm size that were glimmering in purple and obsidian appeared on his chest out of nowhere. They could feel they were a little heavy...The obsidian one, the mystic egg, was glowing black and giving a warm feeling as if it was ready to hatch...On the other hand, The lord beast's core was just like any other core.

"You might be surprised to see the lord beast's core but they don't disappear like other cores so you can still use it. 

As for the second one, I have infused one of my precious treasures with this mystic egg, this would let you receive a hundred times better reward than you were supposed to get when you hatch it...But remember to infuse your mana in this mystic egg only in front of all three girls..." The girl reminded him of the condition and told him how she enhanced the mystic eggs to a higher level.

"Why would you do that???" he asked, scrunching his eyebrows.
