Grandpa Lou, having lived in the world of Warlords, is indeed very familiar with Vallebang's situation.
He's a healer, and while he has a doctor's benevolence, he also has to consider profits.
In a place like Vallebang, it's impossible to survive without thinking about benefits.
If he only considered morals and not profits, Grandpa Lou might have been killed or starved long ago.
The benefit that Grandpa Lou is considering now is for Weng Xingban and Ruan Yu. Because these two kids, they're carrying too much burden, which is really pitiful. Such a valuable pilot can bring enough money to clear their debts.
For this reason, Grandpa Lou not only carried a medicine box but also brought a handgun.
This handgun, of course, was used by Grandpa Lou when he was living in the world of Warlords. Although it's been more than ten years, he's still kept the gun in good condition, and it fires just fine; the bullets are still good.
