Du Yuanyi knew very well that the main purpose of his trip was to clean up Du Yuanruo's mess. Otherwise, his bastard brother would die under the Third Prince's knife.
Even if the Third Prince was on good terms with his scumbag brother, that was only possible if they didn't threaten or harm the Third Prince's interests!
Moreover, the crown prince was still in power.
Now was the critical time for the Third Prince and the Fourth Prince to compete for that position. If he really lost in front of Pei Qian, the consequences would be disastrous.
The Third Prince wouldn't let his useless brother off the hook!
So, here he was.
Yes, his brother was a good-for-nothing! But he never expected him to be useless to this extent!
A northern barbarian had actually infiltrated a small refugee camp!
If this continued, the consequences would be terrifying!
