The Soul Filling Technique

Three days later--- Planet Jura spirit domain---

"...." Richard's silver spirit embodiment remained seated with his eyes closed and his hands on his knees, then he opened his eyes and sighed, then looked at his father's back, "Well I've finished digesting all the soul techniques you passed on to me, and I've also absorbed everything you told me about the Soul Domain, I believe I can enter and exit it as I please now."

"Oh, so fast?" Robin let his finger run over the image of Planet Jura and loosened his knitted eyebrows before looking back happily, walking towards Richard, "Excellent, it's time for me to pass on to you the last soul technique I made, if I can combine it with your mass killing methods then I believe that no one will be able to stop you, not in the young planetary belt, nor the middle one!"
