So at that time, they were all very grateful to her.
However, Yan Ji wasn't polite with them, and directly demanded that they make a promise to unconditionally agree to one condition of hers. They agreed, forced by social pressure and by Yan Ji's authority.
Yan Ji saved their lives and made such a request. If they did not agree, she might send someone to the Western Paradise!
But later, after Yan Ji died, they forgot about this matter, thinking they would never have to fulfill the promise in their lifetime.
Now, suddenly hearing Hao Yansen bring it up, everyone was surprised.
What is he bringing up this matter for? Is he going to demand they unconditionally agree to something?
"Asen, you wouldn't be asking us to unconditionally agree to let you marry Luoyun, would you?" Hao Zaiye instinctively asked, "We do owe your mother a favor, but it's owed to her."
Not to you.
So they would not unconditionally agree to anything from Hao Yansen because of the favor owed to Yan Ji.
