The container was only palm-sized, so inscribing runes on it—especially several different runes that had to work together—naturally cost Chen Mo a great deal of effort. If not for the replenishment from Spiritual Liquid, the consumption of True Essence would have been secondary; the exhaustion of his Spiritual Sea might have been impossible to recover from.
The finished container was ugly, but usable. Completing it in such a short time was also due to Chen Mo's usual practice in inscription techniques.

After finishing the container, Chen Mo swept out with his Spiritual Sense and found the Mother and Child Ghost spacing out at the edge of the formation.
The Mother and Child Ghost had become increasingly transparent, their forms rippling unstably like waves on a lake as they gradually weakened. They had been lingering at the Barrier because they wanted to ram into it, only to discover that their lack of energy could no longer stir even the slightest ripple.
