Suppress the Time-Travelers, It Turns Out My System Is so Powerful

Shen Ci traveled to the world of One Piece and obtained the salted fish system, and the salted fish can become stronger! I thought the system would make him invincible and dominate the pirate world just like in the novel. Who would have thought, this system is extremely weak. After more than ten years of practice, the Sixth Form of the Navy has just reached its full level. Just when Shen Ci wanted to overthrow the system and end his salty life. He discovered another time traveler, who not only came from the same world as him, but also carried a system, and most importantly, it hadn't started to develop yet! Therefore, based on the principle that time travelers are incompatible with each other, Shen Ci took action without hesitation. However, what he didn't expect was that this move actually opened the correct way to use the system! "Congratulations on killing the person carrying the system and gaining the strongest talent." After continuously killing the time travellers, Shen Ci suddenly discovered it. It turns out that my own system is the most defiant, and it is more than a billion points better than other systems!
