If Nangong Li could not give a strong enough reason, the Emperor would not easily pardon him. However, he did not want to expose Asura's existence.
At least not now.
His plan was to use Asura to secretly eliminate Yan Jiuchao and the others, leaving only Yu Wan and her sickly mother. At that time, he would use Asura's advantage to compete with them who had the holy artifact. Without anyone to rely on, they would definitely lose to him like duckweed.
Everyone was happy.
After that, perhaps the Emperor would suspect that he had killed Yan Jiuchao. However, firstly, the Emperor did not have any evidence. Secondly, he was already dead. Could the Emperor abandon him, his only heir, for a few dead people?
But it was different now.
