Steve stayed in the eighth level and began to train. He took the Fantasy Serum and accelerated his training by 3.7 times.
However, after reaching a basic cell value of 300 points, Steve's progress rate had only increased by one or two points each day. This was normal, as the progress rate would naturally slow down as time went by. Then, after reaching a basic cell value of 500 points, it was normal for one's progress rate to once again begin to increase just a little every few days.
But, Steve's progress was in a fast-developing stage. As such, his training speed had improved exponentially with the help of the Fantasy Serum and the Original Gravity Tower!
An hour later, Steve's basic cell value rose to 310 points. Another hour later, Steve's basic cell value increased by two points, bringing it up to 312. Meanwhile, Steve's brain development increased to 11% within two hours!
