Apart from not experiencing the Tribulation Transcendence trial, Meng Chuan was effectively at the Essence Soul Sixth Tribulation realm. He naturally wasn't afraid of Grandsire Three Stones.
If the other party refined and controlled Earth Cloud Mystic Realm as its owner, Meng Chuan would have no chance of fighting him! In a mystic realm, the strength of that mystic realm's owner was terrifying. Sixth Tribulation Eminences would only be sending themselves to their deaths if they went.
It's still too early for him to control the mystic realm since he just headed to Realm Manor. Meng Chuan was rather confident.
"Dad, are you going to challenge him?" Meng An found it unbelievable. Meng An was willing to risk his life to save his wife and child. However, he knew how powerful a Sixth Tribulation Eminence was. He didn't have any intention of barging in. He only wanted to rely on negotiations to save his family.
