It wasn't Mou Yunying stopping An Jing, but Mou Yunying stopping himself, from attacking Concealing Shadow True Lord.
Upon hearing this, An Jing didn't ask, 'You can't even defeat me, how would you attack the True Lord?' such a foolish question. It was obvious, the Shangxuan Sect had its means; as long as Mou Yunying completely became their tool, they would have ample methods to deal with Concealing Shadow.
He went straight to the root of the issue: "How do they control you? Mou, with my sword, whether in law or causality, it shall be cut!"
In Mou Yunying's eyes, the sword of [Killing Life·Calamity] shimmered with incredible light, and behind An Jing, five-color bright and dark seven-layer light wheels rotated, making even this young Martial Artist, half-Immortal Fall, widen his eyes: "So, you are..."
"But... too late."
