Himmel Soan was a fast reader because he could scan whatever he was reading with his mental force.
Viclan had reached where he was after spending half of his life in scientific research. Himmel Soan could reach his level in a matter of days.
They had ten days to prepare for the event. The Earth would be affected on the 11th day.
Ten days would be enough.
Himmel Soan was confident that he could master all the knowledge in the next few days.
He knew how the Void Definition worked, but he needed an external device that could work as his body and release an air cannonball with a tremendous force.
He would rather do the research himself than give the job to others.
Before, he didn't think the work was important enough. After all, as a cultivator, his body was his best device, and his spiritual essence was the best form of energy. He could achieve the effect he wanted on his own.
