The novel I recommend to you is Mystic World Envoy. It mainly talks about one of the directions of casting in immortal cultivation-artifacts. The main character, Gu Ran, chose to forge a sword, but he also practiced the Artifact Seal when he cultivated the Blood Seal. In the novel, the power of the Artifact Seal was very great. Gu Ran's senior brother, Li Daoqian, once recommended Zhong He Ding, saying that "a great bloomer who succeeds late will shock the world and can rule the world for thousands of years." In the end, Gu Ran built his own city, Yuqing City. The city had the support of the various artifact seals he had forged, making the city even bigger and stronger. I hope my recommendation can meet your needs. If you like it, remember to tell me~
