Review Detail of dukroger in I Time Travelled to TITANIC. Help! I want to go home.

The MC is very imbalanced, it got too much power too quickly and too easily, the only reasonable power is that of Skynet and the nanorobots. Maybe it will improve with time, but I couldn't bear to continue reading, I wish the author luck. The initial idea and interaction between characters is not bad, if the negative points are changed it could become a good story, there is a story here in the web novel in which Jhon Snow gains nanorobes and various abilities and powers resulting from this, this would be a more compatible example and without exaggeration for the world the wto is in.
