This was not the first time that Song Shuhang had gotten fortunate enough to touch upon an illusory reality.
In fact, when he had been in the Fifth Stage Realm, he had experienced something similar after meeting Scarlet Pupil in the Black Dragon World.
At that time, he had drawn from his previous experiences of 'death', and constructed an illusory reality five meters around his body—beginning from the slaughter in the scholarly faction's world of the golden lotus, to the tragedy where his body had been refined into an artifact, to when he had gotten his hands on his pseudo-eternity body and resurrected, to when he had imploded on his own, to when he had been stabbed to death by Senior White's clone, and many more.
The experiences that he had built up over his life had allowed him to build an illusion of death layer by layer.
