At that moment,
the Great Tang Emperor took the initiative to speak out and asked,
"Master, may I know the purpose of your visit this time?"
The Great Tang Emperor knew that Cheng Guang would not come to Great Tang Chang'an City without a reason; there must be some other task for him to perform.
Last time, the task that Cheng Guang had assigned him, the suppression and control over the Great Yan Dynasty, the Emperor himself had failed to accomplish.
For this, he had blamed himself for some time.
Now that Cheng Guang had come again, the Emperor was prepared to make amends.
If he were to fail again at the task Cheng Guang set for him, then what else was there to say?
The Emperor could not even forgive himself.
Once or twice was still okay; even if the task wasn't done perfectly, it didn't matter.
The Emperor was just afraid that the Duke's Heir Cheng Guang would be thoroughly disappointed in him.
And then, he would be abandoned, and Tang Chang'an City would be taken back.
