Warhammer: Starting by Saving Horus

This introduction tricked me into it. After reading more than 20 chapters, when can I introduce this plot? Also, at the beginning of entering and exiting the sub-world, I thought there was some foreshadowing, but it turned out not to be the case. I generally feel that the whole plot is that the four evil gods each give some abilities, and then the protagonist of Balabala upgrades and becomes invincible. I thought the protagonist was some kind of hidden god from the beginning, and it is a bit long-winded. I feel a little tired after reading it.
