The Secret Passage

Ace asked again, "Assassin?" 

"Yes, I'm an assassin and it's true!" Jason nodded grimly.

"I believe you." Ace said with a weird face, "But what kind of assassin told his real identity outright? And why did you approach me? I wasn't your target, was I?" 

Jason was astonished because he didn't expect Ace would believe him so easily. Although he was telling the truth, it was also a test to check if Ace was telling the truth about finding true or lies.

Now it was even more difficult to fathom this unknown fellow's limit. Jason decided to take the gamble.

"My life is more important than some silly assassin pride!" Jason scoffed, "As for why I approached you; I have a secret skill, with it I can sense 'Baleful Qi' on someone. You didn't have any of it, that's why I approach you, but I didn't think you were so strong. I have never seen someone as strong as you without baleful qi." 

Jason said. He has regained his calm.
