Professor Argon is most likely to be the only person who can help him solve the problem without compromising anything, but he can't risk a misunderstanding drifting the two of them apart. So after careful consideration, he had to go with the second option only. Even if this person's trace wasn't discovered by his men accidentally he would still send royal guards and investigators to search for someone who has the capability to prevent Xixi from leaving this world.
The person who captured his heart was yet to be aware of this dark side of his and he couldn't be more grateful for that.

Ziran turned to look at Xixi blankly. He was yet to register her question in mind but her way of addressing him made his brain go empty.
