Review Detail of liqeye in Heaven-Defying Comprehension, I Make Conqueror's Training

it was a good start but it failed my expectations. I was expecting some more focus on him researching haki and other skills innovating things with it but they just summarized it by saying 4 years has pass and no explanation. they just say his strong yet and good at teaching. they didn't explain what he learned in the 4 years time skip and focused more on the story. I just thought it could be more awesome if he focus on that cause he has ultimate comprehension.
