The Second Prince's
Help solve the case [2]

"Their guess could have been one of them. However, this is indeed a little difficult." muttered Yi-Feng.

'Sit difficult?' some people immediately set their sights on the young man who had just been present in this department.

"No clues were left behind, not even the assassin's weapon knew, as if he had found something that could be used to kill everyone. This is where it is difficult for us to find these clues" Yi-Fang said.

"Did no witness see it?" Yi-Feng asked the investigators.

"Witnesses? Forget it, even the witness is unbelievable." Reply Investigator A.

"So, there are witnesses?" Ask Yi-Feng

"We said if the witness was not to be trusted." The researcher B

"Why indeed? Why can't you be trusted?" Yi-Feng was astonished by this attitude of theirs

"Have you ever talked to a lunatic? ..No, right? ..The witness here is a madman who used to roam around the capital" said investigator C.

"Ehh? A madman? This is indeed strange," It's true, the words of a madman are indeed unbelievable, it's fitting that his brother is up to this in handling this case.

"What does the killer kill by breaking the neck? Couldn't it?" Guess Yi-Feng

Everyone shook their heads, "Doctor has checked, there's no severe bone in everyone's body." The researcher B

"Then, a drug or a poison?" Keep Yi-Feng

The others returned to shrug, "no. The doctors have also checked, there's no poison in their bodies."

"In fact, if they were to use even poison, one would experience pain as the poison worked. People's houses are close together on the outskirts of the capital, there's no way no one's listening to their cries of pain."

"Then, if you use poison how can a two-year-old get away? There's no way this is happening."

"Hey, no sign of their necks being slashed? Don't forget that just using a thread someone can kill" Yi-Feng said

"It could be like that?" Yi-Fang asked in surprise

"Of course, there are two arteries in the neck that can make a person die in just one minute. The carotid artery takes 12 seconds and the Subclavian artery 3.5 seconds. Not for a minute, someone could die." Yi-Feng said casually just like he was explaining a schoolboy's lesson.

"Ar-what was it? So where do you know that?" Ask researcher C who became curious.

"Arterial, the roughness is the same as the vein. Someone who committed suicide by cutting off his wrist, a pretty dangerous place." Clearly Yi-Feng again

"Can you explain where you know all this?" Yi-Fang asked.

"Of course learn from books... Anatomy and physiology, I read it in my book." Well he didn't lie okay? It was in the medical books he had read

He wouldn't have known this if his sister hadn't forced him to study. Axila is very hard when teaching her to learn the system of the human body, especially when learning to sword and shoot.she must know the opponent's weak points, weak points of death the fastest and so forth.

He doesn't want to learn these terrible things, but his older sister is a secret agent and his sister-in-law is a mobster. Enemies are everywhere, how can he not learn to protect himself?

Yi-Fang did not ask where this book that his sister said came from. He was curious, but kept his question because there were still people around them, he did not want to make his twin sister even suspected by these investigators.

Yi-Feng turned to his twin sister. "Have you seen the body?"

Yi-Fang nodded, "already."

"Can I see it too? We might be able to find a clue there," Yi-Feng said

Investigators looked at each other, they found no clues. So, how could this Prince get a clue?

"In there it stinks because the bodies are slowly starting to rot, are you sure you want to come in?" Say Yi-Fang again

"I'm going in, we can look for clues in those corpses, no matter how small the clues are and how thorough the killer uses the technique, there must be little things that are not noticed by him." Yi-Feng said quite confidently about this

"Well, be prepared because it stinks in there." Said Yi-Fang resignedly, his sister is quite stubborn as well. They walked to the morgue

"Sure, but is there no cure or potion to preserve the corpse?" Yi-Feng looks towards Yu-Cheng

"Your Majesty, indeed have found this corpse preservative. However, this only lasts for three days, after which the corpse will rot." Yu-Cheng explained

"That means, this preservative has not been effective. The doctors had to do a lot of experiments to find formaldehyde" Yi-Feng murmured

"The preservative of this corpse was also found by a long-dead member of the imperial family." Said Yi-Fang with a hint of pride

"Oh yeah?" The beautiful young man immediately turned to his twin sister.

Yi-Fang nodded, "Of course. Just two different generations from us."

"Who is he?" Yi-Feng asked curiously, "can you tell me without cutting it? I was curious, okay?"

Yi-Fang chuckles softly, the brand continues to walk while chatting so that it has unconsciously arrived at the morgue.

"It was the Empire's great-grandmother, the great-grandmother who took care of the Imperial Father and Aunt when they were young back then.

There is a reason why Grandma created this preservative called formalin. However, the great-grandmother also said that if this is only 40% successful so it can not preserve the body for more than 3 days. The doctors are still looking for ways to make formalin 100% effective and work" Yi-Fang explained proudly

"Grandmother great-grandmother? ... Isn't he so great?.could find this formalin," Yi-Feng was quite happy yet he suddenly stopped his steps which left Yi-Fang, Yu-Cheng and Zhou Yang astonished

"So you said this corpse preservative is called Formalin?" Ask Yi-Feng again

Yi-Fang nodded, "grandmother who called the name of this herb 'Formalin'. What's wrong?" Of course this young man was confused, what was with his younger brother who looked this surprised.

'Formalin? .. Is this not the name that is called in the future? How could there be in this ancient era? ..It's not possible'

[Why are you surprised? ...You look very strange.] Louis' voice suddenly sounded in his mind

[Hyung, what do you think?] yi-feng replied

[When did I become your sister? ..I'm your teacher stinking boy!] Louis is upset by this call, okay?

[Tell me what do you think? ... Formalin is not from the future?] yi-feng asked and paid no attention to Louis who was a little upset.

[Well, this is pretty weird. You can find out about this later, so your curiosity is fulfilled.] Louis reply ya g also felt strange

"Your Majesty, what is it? .. Do you feel unwell?" yu-cheng asked who saw his master had a strange expression on his face.

Yu-Cheng's call brings Yi-Feng back to the real world, "Nothing. I just feel a little dizzy, maybe because it's noon and I'll be in for lunch." Yi-Feng reasoned indistinctly

However, he did not expect it to make them worry
