Regarding Duanmu Huai's single-handed destruction of a star, Sister Shepard was just briefly shocked, and then quickly put the matter aside.
This is quite normal. If the Tribunal hadn't previously demonstrated the ability to destroy planets, Sister Shepard might have become frantically worried. But, in fact, the Tribunal has eliminated not less than a thousand, possibly up to eight hundred planets, and Sister Shepard has witnessed this several times. Seeing it frequently numbs her, and at most, she just assumes it's likely another new star destruction technique developed by the Tribunal.
Anyway, if the results are good, everything is good.
Then Duanmu Huai listened to the report of gesturing and drawling from Shepard.
Simply put, Sister Shepard is faster than Duanmu Huai, maybe because she has a more explosive temper. After tracing that mysterious signal all the way to the coordinate point, Sister Shepard immediately discovered the yellow-brown planet and decisively landed on it.
