"Detection-type wizard spells are divided into two kinds: enhancement-type and probing-type..."
Enhancement-type spells did not require much special research. After all, repeated enhancements brought no additional boost; he only needed to buy a few more corresponding Wizard Artifacts.
The key lay in probing-type detection spells.
"Most conventional probing-type detection spells worked like radar. Each use returned one set of results. Although the consumption was low, it did create gaps in surveillance."
Although there were spells that could continuously return feedback, compared at the same level, their effective range was far smaller than that of probing-type detection spells that returned results in a single burst.
"I can solve that problem, but there's another, more important trouble that can't be dealt with."
Besides the issue of mental power consumption, the most important factor in probing-type detection spells was a wizard's information-processing ability.
His Rune Artifacts had been created on the basis of the Immortal Cultivation System's high-intensity absorption of external energy. They only needed activation and consumed very little energy.
If detection abilities were solidified into Rune Artifacts, he could continuously cast detection spells without worrying about consumption.
But even if he truly made Rune Artifacts this way, Benjamin's results would not differ much from an ordinary wizard casting spells, because his information-processing ability could not keep up.
Too much information would affect his thinking, even clogging his mind.
If he used Rune Artifacts to release detection spells too frequently, then the enemy would not even need to make a move—Benjamin could break himself first.
That was why most probing-type detection spells were designed to take effect in a single burst rather than provide continuous enhancement.
With the wizards' research capabilities, it would be quite easy to develop a probing-type detection spell that could be used continuously while maintaining the same range
