If this matter cannot be resolved quickly, Yu Tianqian will become increasingly restless.
Moreover, before the fake Meng Fang left, he clearly told Yu Tianqian that Shangguan Linlang was not in Nightmare City. 'They' spoke with such certainty, it didn't seem like an act.
That person definitely also has clues about Shangguan Linlang, but 'they' just don't intend to disclose them.
Then there's the matter of the Yan Beast's whereabouts. What change has occurred to make the Yan Beast leave Nightmare City...
All these things are causing Yu Tianqian anxiety. He worries that this is just the 'ripple' on the surface of the water, while beneath where no one can see, a massive undercurrent is brewing, ready to erupt into a terrifying storm at any moment.
And once such a situation arises, a lot of people will probably be affected.
As the Heavenly Emperor of the Eastern Celestial Court, Yu Tianqian is even more worried that the overall situation might not remain stable.
