I Am Refining Elixir in the City

[No system, story flow] Twelve years ago, six-year-old Xia Peng was pushed into the Donglin River by bullies and accidentally transported to a different continent through a time and space tunnel. Twelve years later, Xia Peng learned alchemy skills and returned from another world. This time, Xia Peng will use alchemy to control his own destiny. As a kind person, I heal the sick and save people, and I hang the pot to help the world. Evil man, I will give you a half-stepping smile that splits muscles and bones. To save my compatriots, I put myself in danger and lurked in the enemy's country. To kill traitors, I wield a sword thousands of miles away, and I will kill them no matter how far away they are. To defend against foreign enemies, I will protect the land of China with an innocent heart.
