Given Qiao Dongliang's character, if he stayed in the army, his good prospects would be ruined by him.
A soldier should not have such behavior.
Zhai Sheng knew vaguely that the Qiao family felt that it was because of Qiao Nan that Qiao Dongliang had to leave the army and gave up his chance of promotion.
But in Zhai Sheng's opinion, it was good that Qiao Dongliang left the army because of Qiao Nan.
Otherwise, given Qiao Dongliang's situation, if he stayed in the army, sooner or later, he would commit a grave mistake.
Qiao Dongliang might commit mistakes and make a blunder, but what was serious was that he might implicate his comrades.
Previously, Zhai Hua committed a grave mistake and her brother was injured because of her.
