Don't assume that Liu Ji Tong was a benign person; on the contrary, to be able to sit in his position, how could he be a person faint of heart?
Not only did he execute Lang Jun Cai, the old man also gave the Lang Family an empty criminal charge, killing all their elites while the leftover women, children, and old were exiled from the Extreme Yang City; he was truly vicious and merciless, almost destroying the Lang Family.
The old man certainly had reason to be enraged… Liu Qi Yuan originally wouldn't have come into conflict with Ling Han, and it was completely instigated by Lang Jun Cai. If he weren't there that day, then what end would Liu Qi Yuan have met?
This was almost equivalent to hatred of killing his grandson, so the old man naturally didn't hold back when he acted.
With one day's effort, the Lang Family vanished completely from the Extreme Yang City, demonstrating the amazing capacity of an Earth Grade alchemist.
