Arknights: The Deathless Black Snake Wants to Live a Simple Life

I, the immortal black serpent, reside in Ursus, a young and promising immortal. I lack the overwhelming power of monstrous calamities, the potent corruption of demons, and the boundless adaptability of the Sea Child. Though I possess strange memories, I am certainly not as old as my predecessors. My only dream is to die a peaceful, natural death. I adopted a simple-minded child who constantly opposes me and urges me to join her in her demise. I befriended a reclusive pen pal who likes to send me landscape paintings, but I always feel she's out of touch with the times. I met a goofy hunter who asked me for [a cool pen].
