Elder Jack raised his brows seeing their reactions and smiled lightly. He thought that they must be feeling shy upon being praised.
He then turned to Max and his expression became solemn as he said "Max, from your fight against the fiery wolf, I noticed that although you've become stronger, your mana core seems to have grown weaker."
"You should know that the mana core is the foundation of everything. If we use some external help to increase our strength in a short time, this foundation becomes unstable, and an unstable foundation causes some irreversible injuries to our mana core and body which hinder our future progress and in some cases leads to death."
"So, I advise you to focus on the consolidation of your foundation before pushing towards the higher realms."
When Max was casting his spell [Calidus Brachium] and after when he used [Death Rain], Elder Jack had noticed the slight change in his expression and guessed that he must be feeling pain in his mana core.
