Zhang Xuan could not be said to be a noble and selfless individual. He was selfish from time to time, and the initial reason that he became a master teacher was not to save mankind but to make use of that identity to access more books… However, there were times when one simply could not back down.
If mankind was massacred, what use would his strength be?
He was no longer the same individual as when he first transcended over to this world. He had his family and his students. The Luo Clan and the Jiang clan were looking to him for directions. There were many people in this world whom he wanted to protect.
In fact, the reason he was so determined to mend the relations between the Luo Clan and the Zhang Clan was for this purpose.
Since the threat of the Otherworldly Demonic Tribe was already on their doorstep, there was no way he would back down at this point in time.
"It's truly reassuring to have you as our ally!"
