Though Yelin did not know what kind of relationship the Lord of Moling City had with the Emperor's family, that did not matter. What mattered was that Yelin could see that the Lord of Moling City cared deeply for this pair of siblings, and this pair of siblings currently cared deeply for him... which was practically equivalent to saying that the Lord of Moling City cared deeply for Yelin.
Now that Yelin had a powerful backer behind him, he naturally felt emboldened.
Of course, this could not really be considered using the brother and sister; Yelin genuinely regarded them as friends. Since they were friends, helping each other was only natural. Should they encounter difficulties in the future, Yelin would also be willing to do his utmost. If they were strangers, even if they forcibly tried to become his backers, Yelin would not accept it.
