Female Monks from Daojie Continent

I accidentally traveled to a different world. I fought hard with a group of female monks and won each cruel and dangerous battle. Finally, I defeated a big conspiracy and gained the sincere friendship of the female monks. After I traveled through time, I started an adventure in a different world with a weird team of monks, mainly female monks. This world is a world without fossil fuels such as coal and oil. A world-class war is going on. The main force of the war is mechas that can only be used by monks. The conventional weapons used by ordinary people are front-loaded guns and cannons.
