The Door of Mountains and Seas Is Opened for You

My mother is sick and the doctor said there is no cure. I didn't believe it. In order to find the immortal grass, I broke into the mythical world in the Classic of Mountains and Seas. Gods and demons are rampant here, dangers are everywhere, and I only have a backpack full of modern medicines. I used antibiotics to save the Nine Phoenix Goddess who was being hunted. She thought I was a powerful person of some kind. I used electric shock to temporarily paralyze the ancient ferocious beasts, and they regarded me as a thunder god descending from the sky. I used geology to find rare mineral veins, and Yu Minguo honored me as an honored guest. I thought I could find hope of saving my mother here, until I discovered: The mother's medical record is exactly the same as the "scar of heaven" that caused the world to collapse. The goddess I saved casually, her revenge for genocide was actually connected to the source of the real crisis. And the ordinary blood flowing in my body is respected here as the supreme - "Chinese ancestral blood". Now, that cold goddess stands in front of me with a sword, facing thousands of evil spirits. She said: "If you want to save your mother, then accompany me first to save this world that is about to collapse."
