The Shang Mang Demon Monarch is a Divine Monarch at the peak of the Seventh Layer Heaven. For Chen Mu, who is not adept at causal techniques, cursing and killing the real body of his opponent from afar is indeed extremely difficult. However, he does not need to curse and kill from a distance; he is a Ninth Layer Heavenly Divine Monarch of the Void Lineage, and only needs to trace along the causal network to determine the location of the Shang Mang Demon Monarch's real body.
Once the location is determined, even if it's at the end of the world, the edge of the universe, he can transcend the void and arrive in an instant.
If the Shang Mang Demon Monarch can break through to the Eighth Layer Heaven, using the techniques of the Creation Lineage at the Eighth Layer Heaven, he might indeed have a chance to completely obscure causality. But at present, the Shang Mang Demon Monarch clearly cannot achieve this.
"Still managed to run quite far."
