In fact, the order Li Tianhua first issued to kill Luo Chao was initially unclear in its description, resulting in Deep Cold internally setting the difficulty between B to A-Class with a ten-person limit.
But upon receiving the news that ten A-Class and B-Class assassins were completely wiped out, the high-level executives at Deep Cold temporarily decided to upgrade the task to S-Class, and also dispatched the S-Class assassin "Humanoid Armored Vehicle" to complete the mission.
Of course, the money required to deploy an S-Class assassin couldn't be covered by Li Tianhua's funding alone.
However, in the many years of operating the assassin organization, Deep Cold has never had a task they couldn't complete.
To maintain the organization's credibility and to uphold its dignity, the high-level executives of Deep Cold dispatched the S-Class assassin for free.
