The soul was the essence of life, as well as the wellspring of spiritual will.
When the soul fused with a Martial Soul and the Martial Soul evolved into a Battle Soul, one could achieve an undying Battle Soul and an immortal soul.
Even if the physical body was destroyed, one could still survive in this world.
Of course, the so-called fusion of the soul and Martial Soul did not mean they became completely one. Rather, they intermingled and complemented one another.
Su Mo's soul transformed into vast spiritual will and entered the Devouring Martial Soul.
According to Ghost Saint Yan Mo, to fuse the soul into a Martial Soul, one needed to use profundity as a medium.
Because the Profound Meaning of Devour had already fused with the Martial Soul, and the Profound Meaning of Devour came from Su Mo's spiritual comprehension, it was an inexhaustible power that could continuously surge forth from his spiritual will.
This was a bridge, a bridge connecting the soul and the Martial Soul.
Su Mo completely immersed himself in cultivation, striving to make his soul and Martial Soul intermingle as he attempted to fuse them.
Time slowly passed, one hour after another.
More than ten hours later, Su Mo slowly opened his eyes.
He had already gained some insight, but success would not come immediately, and there was not much time left.
With a sigh, Su Mo stopped cultivating and prepared to return to Divine Martial Academy first.
Inside the newly built council hall of Azure Divine Palace, Su Mo had gathered all the upper echelons above the Martial Emperor Realm.
"Everyone, I will be leaving once again. The development of Azure Divine Palace will depend on all of you!" Su Mo said loudly as he swept his gaze over the crowd.
