Matthew had asked about Zeller's physical condition.
However, the latter's mental state was not bad.
He told Matthew that his cough had something to do with his Warlock bloodline and was not a physiological disease, so there was no need to worry too much.
Matthew could only be sceptical.
Rheagar and Zeller were busy.
Matthew naturally did not stay idle. In addition to writing letters to call his friends, he chose two key breakthroughs from the fourth-grade spells that could be learned.
These two spells were quite meaningful for the upcoming war.
They were Isabelle's Flight Spell and the Dragon Immobilizing Spell of the Monster Immobilizing Spell.
Ordinary flying spells could be learned at tier 3, but the effects of this flying spell were very ordinary. The starting and landing actions were very slow, and the speed of horizontal movement was only a little faster than when running at full speed.
