"No........... shouldn't be, that guy doesn't have any true qi fluctuations on his body, it looks like he should just be a person who has practiced some foreign kung fu.........", Xue Lingyun muttered in his heart.

"Lingyun, have you heard a word?", at this time, the dragon tooth spoke.

"A word?", Xue Lingyun came back to his senses and looked at the other party with some doubts.

"Well, which will come first, tomorrow or the accident?", Dragontooth exhaled softly and said slowly.

"Which one will come first, tomorrow or the accident..........", Xue Lingyun repeated this sentence to herself, "Dragon Tooth, does this sentence mean that we should cherish the present?"

Xue Lingyun's tone was full of uncertainty, because she knew that Dragon Tooth would definitely not say this to supplement her language knowledge or make her cherish the present or something.

"Ah, this sentence does have such a meaning, but you don't know how many people's nightmares this sentence has been.........." A light flashed in the dragon's tooth eyes.

And the energetic middle-aged man sitting next to the dragon's tooth, his originally plain expression also changed!

"Nightmare?", Xue Lingyun was even more puzzled, what else did this sentence have any special meaning?

"About ten years ago, some of the world's businessmen and nobles, murderous bandits, well-hidden spies, well-known killers, and even terrorists died mysteriously due to various accidents."

"After these people died, the group they belonged to tried to find evidence of his murder after a lot of investigation, but in the end they all came to the same conclusion, that is, 'accident'",

"And it's all kinds of things, so many kinds of tricks, even accidents that can only be possible in theory!", the dragon tooth closed his eyes, as if caught in a memory.

Xue Lingyun didn't interject, she knew that the dragon tooth must have something to say.

"Because those who die in various accidents have a lot of resources and connections in their lives, and if it is one or two deaths, they may really be regarded as accidents",

"Then go to do some investigation of potential safety hazards and the like, but with such a large number of bizarre 'accidents', they firmly believe that the death of these people is definitely deliberate!",

"So, regardless of their previous position, they almost joined forces to investigate, and after a lot of investigation, they finally found that there was one thing in the same thing in the 'accidental' deaths of these people!", said this, the dragon's tooth accentuated his tone.

"What is it?", Xue Lingyun also pricked up his ears and listened at this time.

"That is, these people have heard a word in various ways in their lives, whether it is a relative, or a colleague, or a secretary, or maybe a homeless person on the street",

"'Which will come first, tomorrow or the accident?'", Dragon's Tooth said at an extremely slow pace, as if the sentence had a thousand weights.

"What............ What .............." For some reason, she shuddered to hear the dragon's teeth say it in this way.

"As the investigation deepens, a legend of the killer world has entered everyone's field of vision!", the dragon's tooth tone changed back to normal.

"The legend of the killer world?", Xue Lingyun frowned, she didn't know anything about this.

"Well, ten years ago, there was a very terrifying killer in the underworld, no one knew where he came from, no one knew his name, and no one had ever seen him, not even if he was a man or a woman!",

"But it's just such a person, in just half a year, so that those who have presidential-level security have died in their own accidents",

"Even if they already knew that this ghostly killer had already targeted them, it wouldn't help, they would also die by an accident," Dragonfang replied, nodding.

"I already knew it before?", Xue Lingyun was a little puzzled, since this killer was so powerful, how did the target know that he was being targeted?

As if seeing Xue Lingyun's doubts, Long Ya continued: "Maybe they know that these people have noticed him, or maybe this killer has changed his style."

Later, when he let his opponents die in an accident, he would send them a letter with only one sentence on it: "Which will come first, tomorrow or the accident?"

"And, depending on the goal, the phrase will be translated to the other party in a way that the other person can understand," explains Dragon's Tooth.

"Then this killer assassinated so many targets, didn't he or she fail?, what happened to him or her?", Xue Lingyun suddenly became curious about this killer.

"As far as I know, there is no goal to fail, as for what happened to him .......... later", at this point, the dragon's tooth fell silent.

"How's it going?", Xue Lingyun answered.

"Maybe because he offended too many people, he was rewarded by the world's largest group of killers, that is, the League of Assassins, and .............."

"Like this time, it's a mission to release to all the killers around the world on the World Channel", Dragon's Tooth's face was very ugly, because there were also individuals who were rewarded like this, and they were still the target they wanted to protect.

"Wait............. Dragon Tooth, you didn't say the end of that killer", although he could guess the meaning of the Dragon Tooth's words, but for some reason, Xue Lingyun still wanted to hear the Dragon Tooth say it himself.

"The end of that killer, I don't know, I just know, in the end, the Assassins League canceled the bounty on the grounds that 'the mission has been completed'", Dragon Tooth shook his head, obviously unable to give Xue Lingyun a clear answer.

"But Dragon Tooth, why have I never heard of such a terrifying existence in the killer world? It stands to reason that if there is such a number one person in the killer world, I should have heard about it?"

Because such a number one person must be very famous, when she was trained in the intelligence center of Dragon Soul before, she didn't have even the slightest bit of information.

Moreover, Dragon Tooth did not mention the name of this and that person who became a legend in the killer world from beginning to end, as if he was deliberately avoiding something.

"No, you've heard about it a long time ago!", Dragontooth smiled faintly.

"I've heard of it a long time ago?", Xue Lingyun was stunned for a while.

"The number one killer in the world, Black Caesar!", the dragon tooth said to Xue Lingyun with an extremely serious expression.

"Black ............. Black Caesar............", Xue Lingyun gasped, she suddenly remembered the bizarre death cases that the person in charge of the Dragon Soul Intelligence Center had done before.

Those cases, Xue Lingyun now thinks about it with a feeling of chill in her back, and those accidents are completely coincidental in life.

If someone had set it up, it would have been .............

Xue Lingyun didn't dare to think about it.

"Dragon Tooth, then why do people now only know that the world's number one killer was Black Caesar?Moreover, I haven't heard anyone say that the legendary killer is Black Caesar?", Xue Lingyun looked at Dragon Tooth with some confusion.
