Melia was also distressed to see the Green Family Patriarch trained their son so hard, but she understood that it was necessary. If Keiran didn't train and had sufficient strength to protect himself, then he wouldn't be able to stand tall in the three cities' area when the Green Family Patriarch left.
The two of them knew very well that the Green Family Patriarch's time is limited.
Very limited.
The two of them meditated all night and realized that the mana they accumulated could barely keep their body and life force going. But they needed to maintain this meditation every day to make sure that they would last the longest time.
This also meant that the two of them would never be able to leave for a long distance mission or anything like that.
But considering that the Green Family Patriarch would be the head of Wansu City in the future, it was impossible for him to go for a long term mission too.
