"Brother, you truly are a kindred spirit!"
The middle-aged man gripped Lu Yi's hand and shook it repeatedly. "After all these years, someone who understands me has finally appeared."
He hurriedly ushered Lu Yi into his private workshop. Once they were seated, he personally brewed Lu Yi a cup of tea before continuing.
"I really am researching a Soul Tool that can measure spirit power. It's just that my peers don't think much of my work. And to be honest, measuring spirit power is far harder technically than measuring physical fitness. So far, I've only begun to find my way."
"After all, things like physique, strength, and speed are straightforward. You can take Beast Martial Soul Soul Masters with Power Attack System Martial Souls as your standard, calculate an average, and that's more or less enough."
"But spirit power is far more abstract. Each person's Martial Soul, training methods, and other factors affect it, so the differences between people can be enormous."
"That makes how to measure it, which Soul Masters to use as a standard, and even how to define the unit of measurement major problems."
"And so far, I've only formed a preliminary idea of how to measure it."
Lu Yi understood what the middle-aged man meant.
In this era, spirit power had barely been studied. Everything was still being explored, and no standards existed at all.
It was like measuring temperature by the height a column of liquid reached at different temperatures.
But the units of temperature had been established using water, the most common substance, and taking the temperatures at which it entered different states as reference points.
Water, however, could be found everywhere in nature. No matter where it was, its essential nature remained the same.
The spirit power of different Soul Masters varied wildly.
