To communicate with Nell, there were two possible directions. One was for He Ao to improve his own soul and power. As long as he became strong enough to cross the vast distances of time and space, he could establish contact with Nell.

The red light before him was the gradually dissipating power of the 001 Fragment. Before the 001 Fragment shattered, it had been altered to point toward "K." In other words, "K" also had a strong mystical connection with this red light.
In a sense, He Ao might be able to use that symbolic meaning to temporarily replace the "God of War" with "K" in mystical terms.
