Colin smiled slightly as his thoughts shifted.
The shape of the small elf, Nasi, also began to disappear from the air starting from her arm.
This gave Nasi quite a fright.
"Good Colin!" she cried out instinctively for help.
"Relax, little Nasi, you're invisible just like me." Colin comforted her before instructing,
"I'm going to take you to a place called Siya Continent, which is still a long way away. On the way there, we might encounter bad guys, and then you will hide with me like this.
Remember, Nasi, when you're invisible, you must stay quietly in your little bed unless I instruct otherwise, and don't move."
"Yes, I understand, good Colin!"
Although Nasi's shape was no longer visible, Colin could still imagine her nodding repeatedly.
Colin smiled faintly and removed the Invisible Shadow.
The next second, tirelessly, he cast the Invisible Shadow again.
Thus, Colin continuously repeated the practice.
