Ordinary People, but the World Tree

How does it feel to wake up and find that you have become a sapling about to break ground in the world? ——Thank you for the invitation, I am currently contacting Zulong Daba, asking him to save the cub! At midnight on her eighteenth birthday, Yingying Huangliang, who grew up in an orphanage, had a dream and returned to the Qin Dynasty. When she woke up, she found an emerald crest emerging from her palm, and above her head, there was a World Tree sapling, which was eager to absorb nutrients and grow quickly. When the first emerald green leaves grew, countless afterimages of civilization blossomed into towering trees in Yingying's mind. At the moment of reincarnation of the era, all worlds converge here: ——The emperor star fell and new sprouts broke through the ground! ——You will use the dragon's body as soil to rebuild the world's crown! ——You are also the World Tree, and the World Tree is also you! Yingying:? ? ? Yingying: "..." Just when Yingying felt incredible, thousands of soldiers and warriors in the mausoleum suddenly opened their eyes, and the star map of the underground palace hung upside down and poured into her blood... In 72 hours, the world she lives in will be overrun by high-dimensional creatures and turned into a cruel game ground. Born from the body of a dragon and the incarnation of the World Tree, her mission is to connect the corrupted and semi-corrupted worlds, devour them, and nurture the fruits of the gods. Yingying: Huh? Maybe I can... Ever since, a large-scale surreal and magical live-action game has been launched, and all participating players have only one mission, which is to conquer doomsday worlds one after another, provide nutrients for the world's saplings, and protect the blue planet. Yingying: Zulong Daba, you see, this is the country that Zai has won for you! Reading guide: ①The heroine and the ancestral dragon are super direct blood relatives, which can be understood as the heroine was born from the ancestral dragon. The heroine was originally the seed of the World Tree, which was obtained by the Ancestral Dragon. Later, the Ancestral Dragon fed the heroine with his flesh and blood, so that the heroine could be born! ② The dragon soul of the ancestor dragon Baba is still there. It did not disappear because of the baby. Instead, it became the first god because of the heroine! ③This is the setting for now. If you like it, remember to save it! Intention: When I wake up, I become the world tree!
