As a Knife, It Makes Sense to Fool the Host, Right?

There are thousands of people who have traveled through time, but I was the unlucky one to become a broken knife! Fortunately, there is no unstoppable path, and I like to mention the "original system of all things". As long as you complete the task, you can evolve, eventually transform into a human form, and reach the top again! But the problem is... How can I complete the mission with a broken knife? In desperation, I chose a girl with mediocre qualifications, cute appearance and easy deception to be my "host". "Ding! Congratulations on being selected by the 'Strongest Supreme System'. Girl, follow me to slay demons and climb to the top of the Immortal Road!" "She believed it. So, she went up the mountain of swords and the sea of fire for me, and I hid behind her and frantically said "mission accomplished" to the real system. When she thought she was the daughter of destiny, I was counting the evolutionary points rewarded by the system with tears in my eyes. The capitalist's smile was so simple and unpretentious.
