Their previous plan was Plan A, which was to make Meng Die miscarry and thereby prevent Heaven's chosen child from being born.
Obviously, it's no longer possible to execute this plan, so they can only adopt Plan B, to kill Heaven's chosen child in the cradle.
"Hmph, you dream of killing Heaven's chosen child in the cradle, you're dreaming! To be honest, I didn't even put Heaven's chosen child in the cradle, so your Plan B will also fail!"
"What, I didn't expect you actually didn't put the newborn child in the cradle, this way the child will miss a beautiful childhood, you're too cruel!" provoked the Tomb Raider leader, worried that Plan B would also fail because of this.
However, Meng Die saw through the opponent's trick, and said: "Provocation doesn't work on me because I've already transferred Heaven's chosen child into a Gundam, so he will learn superior excavator control skills from a young age, that's a better childhood than a cradle could give!"
Meng Die seemed very proud.
