The day after Dead Bone entered the Soul Realm and completed the transformation, Duo Lai also easily broke through this major boundary.
Mu Yuan wasn't surprised.
He always maintained a cautious attitude, but he did not lack confidence in Dead Bone and Duo Lai.
Instead, if even Dead Bone and Duo Lai had difficulty breaking through, he couldn't think of how other beings at the Legendary Realm would manage.
Perhaps, like the powerful nations of the Yongxing Empire and the Holy Griffon Empire, they have Miracle Buildings that greatly increase the probability of breaking through to the Soul Realm.
But Tai Xuan did not.
Nor did he rule out that some Lords might privately possess top-tier breakthrough aids.
Mu Yuan temporarily didn't need these.
The breakthroughs of Dead Bone and Duo Lai indeed didn't hold much reference value.
Not just them, soon in the future, those like him, Isloa, and Lu Liu who would step into the Soul Realm also lacked reference value.
