At the peak of the third mortal coil, his power was at a whopping 1,126,400F, or 112.64D, or 1.1264C. That was five times as much as the best of the best in the Blood Skull sect and ten times as much as the best of the best of other sects.
Now that he has advanced to the fourth mortal coil, his power has become 4,096,000F, or 409.6D, or 4.096C. So his power improved by 3.636 times.
This kind of increase is perfectly normal. Every human who advances to the fourth mortal coil experiences a 3.636 times boost of their power.
This increase to one's power after ascending didn't happen at the third mortal coil. But it happened at the second mortal coil. At that time, cultivators at the first transformation of the second mortal coil were two times stronger than those at the tenth transformation of the first mortal coil.
