Feng Tianlan took the letter while she gave the Emperor a suspicious glance. It was not what she'd imagined. She felt that if such a thing happened, she would be eager to kill him when she saw him. But now there was actually a letter from her mother and it was from more than ten years ago.
"The seal was made with your mother's Spiritual Force. No one can open it except you." The Dongshu Emperor seemed to understand what was on her mind and said this earnestly.
Feng Tianlan frowned and looked up at Si Mobai. She thought of what he had said before. The seal in the safety rune used Spiritual Force. Could it be there was really such a thing?
"If you don't believe it, you can let the Demon King test it," the Emperor said.
Feng Tianlan had not yet replied when Si Mobai took the letter from her to take a look at the seal and ran his hand over it. Next, he gave it back to her and said, "It feels the same as the safety rune, so what he said should be true."
