Miracle Doctor, Secret Agent Concubine

The poor little boy without a father and mother was sold and beaten to death with a stick. When he opened his eyes again, a fierce light suddenly appeared in his eyes. Anyone who bullied me or insulted me should be beaten back! The Shennong Cauldron that she fought so hard to protect in her previous life has become one with her in this life. With the heaven-defying treasure in her hands, she is not afraid even if she is running away! She vowed to protect her lost brother even to the death. If anyone hurts him, she will hurt his whole family. However, I originally just wanted to lead a leisurely life as a landlord with my younger brother, but why did I become the uncrowned king?
