Michael spent a long time organizing the storage space of his War Rune.
Since his War Rune's degree of refinement increased a lot compared to the last time he left the Origin Expanse, it was easy to fill it with more stuff. However, he had so much to sell that he had to use his professional Tetris skills to fit most items inside.
"I will be back before the protection barrier disperses," Michael promised his subjects sincerely as the Runic Gate manifested next to him.
It was his 9th day inside the Origin Expanse, and it was not long until the protection barrier would disperse. The protection barrier was up for 10 days, but it was usually not exactly for the entire duration of ten days. Sometimes, the protection barrier would disperse a few hours too early, sometimes it would last a full day longer.
However, there were still rough calculations one could take into consideration to guess how much longer the protection barrier would last.
