He had a severe headache and couldn't fall asleep.
So he lit some incense by his bed and closed his eyes to sleep.
This incense contained a sedative, and thus, he fell deeply asleep in less than a minute.
However, when he woke up at four in the morning, he suddenly discovered the number one Assassin in black clothes and a masked face lying on the ground beside his bed.
Gu Xichen's gaze landed on where the incense had been lit, now burnt down completely.
Obviously, she was knocked out by the incense in his room while attempting to kill him.
He suddenly felt the urge to laugh.
Had the number one Assassin really fallen into his hands this easily?
Yet, he also felt a chilling terror, knowing that if not for the incense, he would have definitely been killed by her.
Immediately, Gu Xichen carried her to the bed in the secret room, swiftly took an anklet from the drawer, binding her ankles with enough length to walk, then tied each of her arms to the headboard of his bed.
