I Have a Vientiane Refining Furnace

Yan Xiaonao originally thought that by traveling through time and becoming the foolish son of the city lord's family, he could live a life of luxury and wealth. Unexpectedly, he was accidentally contracted by the artifact Wanxiang Furnace. From now on, you must continuously supply profound energy, otherwise you will suffer the pain of burning your soul. So, in order to terminate the contract and avoid the pain of burning his soul, he embarked on the path of study and cultivation. When he came to his senses, he was already unbeatable. "I just want to get rid of this curse, why am I invincible?"
