Ah-choo!
Chen Chen sneezed with a confused gaze.
His cultivation level was already at the Core Formation realm, so why would he sneeze? Is someone from the Wuxin Clan cursing him?
'It seems that I have to be more careful in the future, such things as curses really exist.'
"Detection has shown that the host's cultivation level has reached Core Formation and the tracking distance has been increased to 50 meters. In addition, you will be rewarded with one lucky tracking opportunity."
At this moment, the system's belated prompt suddenly sounded in Chen Chen's mind.
"Fifty meters now? The tracking range has expanded greatly!"
Chen Chen was a little excited. Although the difference between 30 meters and 50 meters seemed to only be 20 meters, the actual tracking area has increased nearly thrice!
The surface area of a circle was equal to the square of Pi, something that he learned in his previous life.
