[System + high martial arts + cool writing + protagonist's decisive killing + growth and upgrade]
When Gu Ye woke up, he traveled to a distant alien world.
The world is full of demons and evil spirits.
Gu Ye didn't panic because he had awakened the deduction system.
As long as you hunt monsters, you can obtain deduction points.
[Kill the first-level monster and get 50 deduction points, which can be used to deduce any martial arts for 50 years.
The deduction begins:
[You are not satisfied with your perfection-level swordsmanship yet and want to take a step further.
[In the first year, you get nothing.
...
[In the forty-ninth year, you still gained nothing, but you are a paranoid pervert, even if you hit the south wall, you will not look back.
...
[In the seventy-second year, you finally caught that glimmer of light and entered an unprecedented realm of Taoism.
After obtaining the deduction system, Gu Ye has since turned into a demon harvester. The demon that everyone avoids, he can run towards.
[You start to deduce the 'Five Ghost Transport Technique']
[The five ghost transporting skills are perfect.
[You begin to deduce the ancient magical power 'Dharma, Heaven, Elephant and Earth']
The Dharma, Heaven and Earth are perfect
Endless years later, demons and alien races invaded this world again.
The young man waved lightly, and the sword flashed across thousands of miles, dividing the world into two parts.
The bright sword light is so brilliant that it makes your heart tremble.
With one strike of sword, all races will be destroyed.
"Under the universe, only the human race is eternal."
