The title of the book is bad and has nothing to do with the text. I was confused at the time.
[Combination of Chinese and Western + dual male protagonists + not brainless + multiple systems + Cthulhu + group portrait]
"The Beginning: From Traveling Through the Octopus to Ascending the Villain's Throne" "Rebirth as a Nation to Cultivation: I Evolved the Forbidden Law"
This book tells the story of what a system is, and how a monk with a system of cultivating immortals and a time traveler with an evolutionary system grow and collide with each other to establish their own power.
Li Jin, a scientific research experiment led him to travel his soul to the world of an immortal, and obtained the evolutionary system at the beginning. However, during his first treasure hunt to become stronger, he met Ye Jin, the other male protagonist of the book. From then on, the two formed a rift and was treated as a villain by him.
Later, he encountered Li Jin holding his sister hostage in the elf world, which once again increased the hatred.
In the battle between humans and demons, Ye Jin took the initiative to rescue him, which made Ye Jin waver.
And every time Li Jin is regarded as a villain, it is actually an accident.
