Freelancers in the Holy Ruins

In the post-civilization era, Li Yan came out to look for opportunities and entered a space where many strange things appeared. I heard that you are known as the master of weapon refinement, you think so; Li Yan: I am a freelancer, and I only make handicrafts occasionally. Besides, we have the Weapon Refining Sacred Tree, so it is possible that we can refine weapons by ourselves. I heard that many powerful people regard you as their mentor. What do you think? Li Yan: I am a freelancer. I may say a few words occasionally. We have a perfect library. There are what they want there. There won't be anyone who can't understand it. According to reliable sources, you can travel to other worlds to find opportunities. How do you explain that? Li Yan: Let me reiterate again, I am a freelancer and I will experience different scenery. This is not too much. In short, this is the life of a freelancer walking in the Holy Ruins world and other worlds. (More than 20 chapters in the first volume of the opening volume are in Douluo World)
