She was afraid they would drink her blood, and they were afraid she would be hungry and cold.
She thought she was a reserve of food, but they treated her like their life.
Until the commander, whose face was covered in black markings, spoke to her haltingly in his newly learned Chinese:
"Drink this, it's a nutrient solution, it doesn't suck blood."
"Sleep, this is a hibernation pod, not a coffin. We are not vampires."
"You are the guide, and we are the sentinels."
"Our mission is to protect you."

By chance, Ye Lingxi discovered that Qimen talismans could actually reduce the contamination level of sentinels.
From then on, the legend of the Xuanmen Celestial Masters began in this interstellar space.
With a compass in one hand and a talisman in the other, Ye Lingxi can pull even a berserk sentinel back from the brink of death.
...
Much later, everyone in the Federation knew that on that most remote, desolate planet lived twelve madmen who had crawled back from hell.
They stayed by their only guide's side, never leaving him for a moment, until their deaths.
