Although they were somewhat poor, and life was difficult, Xiaomi wasn't afraid. She had a pocket dimension that gave her everything she wanted in the world! Her space was full of spiritual energy, so she grew spiritual plants and spiritual herbs and also raised spiritual beasts there. Every day, she bathed in a spiritual fountain. Besides that, the spiritual energy in the air that leaked out helped the entire Fuan Village by ensuring the crops were large and fresh! For these very reasons, Jiang Xiaomi became the lucky star in Fuan Village. She later used her clairvoyance ability to create ammunition and large ships. Then, someone wanted her to stay in the capital city and become a government official's wife. Jiang Xiaomi waved her hand. This world is vast. I still want to see what's out there!
