He had no idea that his Royal Brother had been poisoned!
That would explain why his Royal Brother had not produced an heir all these years and had hurriedly appointed Long Chi as the Heir Apparent. So, this was the reason.
As for the person who had poisoned his Royal Brother, it turned out to be Empress Dowager Xiaojing.
He asked with concern upon realizing this, "How is Royal Brother's health doing now?"
Zhao Qian darted him a thoughtful look and patted his shoulder as he replied emotionally, "You're indeed a true brother for being so concerned about Master's noble health, Prince of Xiangyang. Master would be very touched to know this."
The Prince of Xiangyang felt a little self-conscious when given that look, and at the same time, he felt a little awkward. "I'm an official and Royal Brother is the Emperor. It is my job as an official to be concerned over His Majesty's noble health. Don't tease me about it, Butler Zhao."
