"There is one question that hasn't been answered in my mind." Theo frowned, contemplating. No matter how hard he worked, he still couldn't find the answer. Ultimately, he asked, "How do you know what kind of power I have? I mean, it's true that you have been watching over me this whole time, but I'm pretty sure that you can also use this power against someone else. This power can only work if you know them inside out."
A smile appeared when Loki heard that question.
"I have been waiting for that question." He walked to Theo and said, "What are the three rules I asked you to follow in the past?"
Theo nodded with a solemn face. "First, I need to know my and the other party's purposes. Second, I need to be known by many. Third, don't lie."
"What do you think is the hardest?" The God of Mischief asked.
