Comments of chapter undefined of Surviving In The Ancient Times With Limitless Supplies

Feel so bad for Nalan Tuya. In the earlier chapters, didn't she kinda hint/ask her fiancé if they can bring the carbon filter to her tribe but then he acted really angry for some reason....So I dunno what he means by not trusting him enough. He knows how her mom treats her & he doesn't tell her anything. Did he want to force her to 100% choose him? That would mean she need to cut off relations with her widowed mom & abandon her tribe to die...Honestly, the chieftain's judgement is more wise & reasonable. He just decided to kill her off with no alternative...
