After a moment of silence, Han Li indifferently said, "Old monster, when you possessed the puppet, didn't you think of moving your primordial spirit away from the puppet? With your intelligence, it shouldn't be difficult to create this technique, right? After all, you were the one who created the Great Development Technique."
"Do you think that the Soul Attachment Technique I used was very simple? Back then, I relied on my outstanding intelligence that was second to none, so I was distracted by too many things. Not only did I create a secret technique like the Great Development Technique that could strengthen one's spiritual sense, but I also founded the Thousand Bamboo School and figured out puppet techniques that had long been lost in the Heavenly South Region. Just these alone consumed most of my lifespan. Not to mention that I had to cultivate at the same time, allowing my cultivation to advance to the late-Nascent Soul Stage so that I could run rampant and be invincible."
