The men were killing each other while the women were secretly taking control of the Royal Court. Gu Shenwei was willing to be an observer and wait for an opportunity; additionally, he was very curious as to how far Lotus could go.
There was no need for Lotus to act personally and join in on any assassinations taking place in the Royal Court, but she had still invited the Dragon King to join her in hopes of convincing this stubborn killer through reality.
She believed that the Dragon King belonged to the dark night, the shadows, and her.
Gu Shenwei saw that the chaos of the Royal Court had gradually gone out of control as Lotus had expected. The lords had tried to call for a truce but the messengers they sent were either killed or had disappeared, causing more panic.
But Lotus felt that it wasn't enough. She wanted to unleash an inferno of vengeance, regardless of the consequences.
