How long has it been since the start of this training? Truen had lost track of time with the constant visits between the time-space dimension and Merlin's library. Sometimes, it felt as if the elf had gone through five years of studying but other times, it only felt like two days worth of magic sparring. Zero's mana regeneration pills were put to good use and the bodyguard smiled. Without them, he would have lost track of the days that went by in the real world.
