Zhang Chi traveled to the world of "The Days of the Jackal" and became the observer of the original protagonist Jackal, codenamed Ghost!

After traveling through time, Zhang Chi is bound to the King of Killers system. Every time he kills a million-dollar target, he can obtain a killer skill rewarded by the system!

"Ding! Sign-in successful! Congratulations to the host for achieving perfect sniping! The perfect sniping skill will correct all external factors, allowing the host's sniping to reach perfection!"

"Ding! Sign-in successful! Congratulations to the host for gaining crisis perception! Anyone within one kilometer of the host who is hostile to the host will be marked.

Targets that are more hostile and threaten the host's life will be marked in red.

Targets with less hostility and that do not threaten the host's life for the time being will be marked in yellow."

Just like that, Zhang Chi started with system skills and walked into the killer world with the jackal!
