I remember certain arcs and chapters of this story and will be including what I remember so sorry if it spoils the novel if you haven't read it yet. So during one of the arcs, there was a great battle between the humans and beasts. However, the MC has beef with the human's higher ups and actually befriended the beasts. So when he was sent in the front lines to die, the beasts didn't rly attack him. Another thing I remembered was he had a certain tower or pagoda in his body where he unlocks certain abilities which he used to escape the beast's ruler (female) during the battle between the humans and beast I believe. The MC also recruited two beast underlings. which he used to get herbs from them. He also once went to their home and promised to give them a pill in exchange for their herbs.
