Take the nun to the world

Under the tide of crossing, our protagonist finally crossed. This is a story about how a person struggles to survive. PS: This book is based on the setting of Warhammer 40K, but for some reasons it does not fully follow that setting, so please don't set the things inside, and then spray me after you find that it can't be set. (Civilized reading, if there are any mistakes in my writing, please tell me in time...
