Within half an hour, Angel used Potential Eye on passersby seven times in total, raising his maximum by seven points. That rate of improvement was undeniably fast.
Unfortunately, with his energy points being consumed and restored at the same time, he could only use the ability once every three to five minutes.
If his energy consumption could keep pace, Angel would even have been willing to stay here indefinitely.
Besides raising his maximum energy points, the seven uses of Potential Eye also gave Angel a deeper understanding of the ability.
For example, he discovered that Potential Eye actually had a limit.
He had discovered this three minutes earlier. At the time, Angel was still doing as before: waiting for his energy points to recover, then casually choosing someone around Companion Star Lake as a test subject for Potential Eye.
Perhaps because of the time, there were not many people around Companion Star Lake. But the lake was enormous, and the surrounding area was almost entirely flat, giving Angel an extremely broad field of vision.
He could even see people several hundred meters away on the opposite shore.
Using Potential Eye depended entirely on one's line of sight. Anyone within Angel's field of vision could become a target, so although there were not many people around Companion Star Lake, there were still enough for him.
The star ratings Angel measured for the first six people were basically low and fluctuating.
The best among them had a three-star domestic-service potential, with culinary skills as the recommended direction.
Angel did not remind this three-star domestic-service potential holder as he had the doorman before, because this three-star potential holder was clearly a homeowner around Companion Star Lake.
Anyone able to buy or rent a home around Companion Star Lake was at least upper-middle class
