Well, spirit circuits are inside Mechas. Spirit arrays are cast on spirit tools. Lastly, for nodes i think they are in one of these (either mechas or soul tool) but I wouldn't recommend that you mention nodes at all since we have no info on them. Even for spirit circuits and arrays, I would say that you mention them a little to explain it once if you want and rarely talk about them again. It's just that when you write on stuff that wasn't mentioned alot, there's a higher chance of making mistakes. If you still want to, then I would suggest you read up on Mechas and Spirit Tools for spirit circuits and spirit arrays (Forget about nodes in my opinion).

Here is what I found about Spear Intent and the levels after it that Tang Wulin comprehended. (I guess essence could be thought of as finding your own way? Like some kings are kind, some are tyrants, some are conquerors, etc.) Spear Intent: Appeared as platinum spear projection. Integration of spear and essence. By comprehending the king's heart, he learned to use the king's spear, claimed to be the king of weapons. Spear Soul: A true Spear Soul is a Spear Intent that strikes straight for one’s soul, the true fusion between a man and a spear. It is not One with the Spear, or Uniting with the Spear, but it is the true fusion of one’s soul and spear. Its power affects the target physically and spiritually. The spiritual assault appears to the opponent as if the spear became illusionary and projected into the mind. Integration of spear and energy. Spear Spirit: Alt. Name - Spear God Integration of spear and spirit. The utilization of spear to command the power of heaven and earth laws with his attacks. One with the Nature: Alt. Name - One with the Heaven or One with the World

Thanks for the amazing chapter 😊. Really looking forward to reading more.

Yes, there is sexual content in the novel, but it's after a couple hundred chapters. It's also very light as this novel focuses more on the story rather than the sexual content. Though there is a lot of character development and romance.

Well, there isn't just Acnologia from Fairy Tail that's in Douluo Dalu. Zeref is also with him. Also, we see plenty of abilities from the Fairy Tail world in Douluo Dalu too. Overall, I think it's worth it to read this novel if you're a Fairy Tail and Douluo Dalu fan.

I don't know what you mean by snu snu. If you can clarify, then I can try to answer.
