Soon, Angel deduced the limitations of the Gate Model from the existing information.
Once Angel used this new Gate Model, the special energy contained within it would reset to zero again.
That is to say, when Angel cast the new Gate Model, if he wished to use it again, he would need to wait for the special energy within the model to diffuse again before it could be used.
Angel did not know how long it would take for the special energy to diffuse and fill up after resetting to zero.
But due to this limitation, it undoubtedly told Angel that this new Gate Model should not be used casually.
Moreover, this limitation on usage was only what Angel could deduce so far.
Beyond this, Angel could feel that there should be some other limiting conditions for the Gate Model, but he was currently unable to deduce what they were. Only when he really used it would these limitations gradually become apparent.
