Fang Li was not a Magus and had no way of supplying magical energy to a Servant.
Even ordinary magi knew such things. How could Fang Li possibly have failed to consider it?
Not only did a Servant's manifestation and combat require the consumption of magical energy, but even a Servant's strength was affected by the amount of magical energy possessed by their Master.
If Fang Li simply summoned a Servant, leaving aside how to handle manifestation and combat, even the Servant's strength would be reduced.

Since it specifically stated that he had to assist as a Master, that meant Fang Li could not participate in the battle directly and could only provide support from the sidelines.
In that case, if the Servant was too weak, it would greatly hinder the mission's progress.
With that in mind, Fang Li had no choice but to consider the issue of supplying magical energy.
And when that problem presented itself, Fang Li immediately thought of Yggdmillennia.

Under such circumstances, Masters and Servants were essentially in a
