After Traveling into the World of Beasts, I Turned into a Rabbit

Jian Yi woke up and found out that he was a cannon fodder and knew the contents of the entire book. Before he could counterattack, he traveled to the beast world and had a handsome bodyguard by his side. Jiu, as a system, accidentally killed the host before he could lead the host to counterattack at the beginning. In order to save the host, he could only travel through the beast world. In order to make up for it, Jiu started to be the host's bodyguard, but unexpectedly, he also lost himself.
