The Empress Tianhong no longer harbored any thoughts regarding Lu Chen reviving her.
If Lu Chen truly had the ability to revive her, he probably would've done so by now.
Now, she suspects that when Lu Chen mentioned resurrecting her on the Immortal Boat, it was merely a ploy to see if she possessed any autonomy.
At that time, her utter lack of reaction likely convinced Lu Chen that she did not possess self-awareness, and thus he lost interest in her, leaving the Feihong Immortal Boat discarded within his inner world ever since.
Well, if she couldn't revive herself with her own strength, how could others possibly do so?
She would continue to accumulate soul strength, hoping that one day she would find an opportunity to resurrect herself.
