Well, it could be about Naruto suddenly finding out that the broken seal has unleashed some ancient and powerful chakra within him. Maybe he has to learn to control it quickly to face a new, powerful enemy that has emerged because of the seal breaking.
Perhaps the broken seal releases a spirit or entity that was trapped. Naruto then has to make a deal with this entity. It might start as an adversary but then they form an unlikely alliance. For example, the entity could offer Naruto unique powers in exchange for helping it regain its lost form.
It could be an old enemy of the village who has been waiting for the seal to break. Maybe someone who was imprisoned by the same seal long ago and now wants revenge on the village for sealing them away.
In this fanfiction, Naruto might gain new and unexpected powers. Since the seal is broken, the Nine - Tails' chakra could be unleashed in a more uncontrolled way, leading to both challenges and opportunities for Naruto. He may have to quickly learn to master this new - found power or face being consumed by it.
One possible plot could be that Naruto, as a seal master, discovers a new and dangerous seal. Anko, being curious and fearless, joins him in his investigation. They might face various challenges, like enemy ninjas who want to use the seal for evil. Along the way, Naruto could use his seal - making skills to protect them and Anko would use her combat skills to fight off attackers.
One possible plot could be that Naruto's family, perhaps his parents if they were alive in this fanfic, reject him because of his status as a jinchuuriki. They might see him as a danger or a disappointment, which breaks Naruto's spirit who has always longed for family love.
I'm not sure specifically as there could be many different takes in fanfics. Generally, it might involve Naruto dealing with the consequences of a shattered seal, perhaps new powers emerging or new threats arising from whatever was sealed before.
I'm not sure specifically about the plot of this particular 'Naruto Anko Contract Seal' fanfic as there could be many different interpretations and stories out there.

Maybe Naruto uses his ninja skills in the context of Navy Seal missions. For example, his ability to move stealthily could be very useful in covert operations.
Well, it could be about a Naruto who becomes a master of seals in Kumo. Maybe he goes there to learn unique sealing techniques that are different from those in Konoha. He might face challenges from Kumo ninjas who are jealous of his skills or don't trust an outsider mastering their precious arts.
Perhaps in the 'broken lamp fanfic', the broken lamp is a family heirloom. The main character is heartbroken when it breaks and goes on a journey to find someone who can repair it. Along the way, they meet different people who have their own stories related to lamps or broken things in general. The story could also touch on themes of nostalgia and the importance of family traditions as the character is so determined to fix this broken lamp that holds so much sentimental value.
I'm not sure specifically as there could be many different interpretations in such a fanfic. It might involve a story where Naruto's world or a character within it has been damaged or changed in a way that seems irreparable, perhaps due to a great battle, a dark curse, or some extreme betrayal.
