Told supreme mage everything only a couple chapters in

The beginning of the story and the novel is already just pushing mc and gwen to be together. The mc has the omnitrix but works on joy energy which forces him to be a hero and shuts down on negative energy. After traveling to the marvel movie verse he creates clones of himself and acts as plumbers to join the avengers with different alien forms. Also he basically outs everything about Thanos and the infinity stones from the beginning. He does fix the omnitrix by hacking it so no time out and access to basically any alien.

Becomes terrible after joining rocks.

It's alright in the beginning but later the chapters only write about his actions one day at a time there is no time skip. Up to 350 chapters it's only been 3 months in the story

Why are almost all action scenes just nonexistent? In the beginning there was a few but later it seems to just skip to the ending
