It was clear.
The Great Tang Emperor was not entirely spineless.
Right now, he was bowing to both Guangyin Buddha and Cleansing Thought Buddha only because he did not know their intentions. Moreover, he did not understand why the Western Buddhas suddenly appeared at this time and what their purpose was.
He also did not know why these two Buddhas had suddenly appeared in his Yangxin Hall and what they were here for.
With a mindset that more trouble is less welcome than less, the Great Tang Emperor thought to avoid angering Guangyin Buddha and Cleansing Thought Buddha as much as possible. If they had any requests, he would try to accommodate them for the time being. Later, after he regained control of Tang Chang'an City from the unknown Cheng Guang, he would make further plans.
The things he had lost,
he intended to take them all back, one by one.
