"From my observation, unless an unparalleled Martial Emperor personally acts, otherwise even if a Martial Emperor were to forcibly kill you, this Transformation Path Wondrous Object can revive you once."
The so-called death substitution means that if you are killed by a strong opponent, this Transformation Path Wondrous Object can resurrect you, taking your place in death.
Of course, the death substitution ability of this item also has its limits. If it's faced with an unparalleled existence like a Martial Emperor that can obliterate even the Great Dao, death substitution is utterly useless.
If a Martial Emperor decides to kill, they can erase every trace and imprint of your existence from the world, and nothing can bring you back to life.
However, if the Martial Emperor does make a move to kill a Saint Realm expert, never mind just substituting once, even if it could substitute a thousand times, it's still a dead end.
