Whittaker was saddened as he got to let go of more than 200 battle energy core. His storage ring was full and he couldn't store it in the inventory that opens up a spatial screen before him. He had to let it go.
"Sigh!" He sighed due to sadness, almost immediately, a small metallic ring decorated with a grayish silver wing on each side dropped from the roof and hit his head.
"Ouch!" Reflexively, his hand moved towards the top of the head where something has crashed. It hurt him because the small ring was made of something heavier than metal and it was dropped from a height, hence it gained momentum. Also, Whittaker bore the frontal brunt of this momentum.
Thanks to the ring dropping on his head, Whittaker also gained deeper knowledge about his Devansha vision.
