Sleepy Mira
After bidding farewell to the three loving mothers, Davis cleaned up the rooms and then finally started cultivating techniques in his mental realm. All his three cultivations were maxed out at Level Nine Immortal King Stage when it came to energy, so he directed all his attention to practicing techniques while time for comprehension was less.
Besides, practicing techniques could invoke insights, so he prioritized that and practiced for ten days straight.
His huge chambers also had a battle room where he spent time with Mira for practical purposes. It was affixed with a spatial formation that extended space on top of overlapping with the temporal formation that covered his entire chamber.
Mira had lowered her cultivation to the Early Immortal Emperor Beast Stage so she could train with Davis optimally. If she used all her power, she would be breaking the formations left and right, not to mention his bones.
