The Legend of the Artifact User

In the distant weather galaxy, there is a star. On the Artifact Continent, everyone has their own exclusive weapon. Some people have swords and other fighting instruments. They can continue to temper their weapons through various methods until they reach the god level. We call them artifacts. When the weapon reaches the third level, it can be added with skills, and its combat effectiveness can be continuously improved by tempering the skills. Tian Meng and Emperor Xue Yan were good friends when they were young, but because they only thought about problems, they became unrelenting enemies. What will happen to Tian Meng (male protagonist) and Emperor Xue Yan (male one)?
