After returning to the estate in the Holy City, Lette wasted no time and set up a compound barrier array for Emily in an empty room on the second floor overnight.
This array was fully functional, allowing Emily to randomly open different elemental subspaces and bless her with several sets of Life Blessings.
Moreover, there were three tests before entering the subspace to ensure that Emily could continuously participate in the "If you're a mage, hold on for 100 seconds" challenge, version 2.0.
Actually, it wasn't necessary for Lette to add so many layers of safety checks, as he had already placed over thirty Holy Light Spells on Emily.
Among them were Holy Rank and superposition spells, even several forbidden curses.
It's tough for her to die.
But for her safety, Lette made all the necessary preparations.
Then he kicked Emily into an unknown elemental subspace and turned around to return to his room to sleep.
Even Lilith the Demon marveled at his incredible mental fortitude.
