Mu Qing took a deep breath and admitted, "...it is true that Feng Xin was injured by me."
Feng Xin was furious: "I knew it must be you!"
Mu Qing explained to Xie Lian, "But that was because the Immortal Capital was in ruins! At the time, all the divine officials were trying to escape, but he stayed behind stubbornly. Even when I told him to leave, he wouldn’t listen. Staying would only lead to him being burned by the infernal flames! I intended to knock him unconscious and hand him over to you!"
Xie Lian replied, "But you didn’t hand him over to me. Feng Xin went missing and suddenly appeared here."
Mu Qing said, "Because there was a little incident along the way."
"What kind of incident?"
Mu Qing explained, "That fetal spirit suddenly attacked from behind, biting me without mercy, preventing me from bringing him along. I didn’t have time to grab him, and then the Immortal Capital began to fall apart, and so..."
So, Feng Xin got swept away along with the ground beneath him, not knowing where he had ended up.
If what Mu Qing said was true, then he had intended to do a good deed but had inadvertently created a mess for Feng Xin, leaving him in an awkward situation.
