Xiao Yiyuan's back injury is serious. In addition, he hasn't recuperated well these days. He has a tendency of aggravating inflammation.

Dr. Hua is in his room to treat his wound again. Lu Hua suddenly comes in from outside in a hurry and says:

"Lord, the bodyguard outside Xia's room reported that Xia was having dinner, but suddenly rushed out of the room and went to the autopsy room."

"Oh... She is brave enough!"

Xiao Yiyuan was both angry and funny.

In more than 20 years of life, Xia Jin is one of the most wonderful women he has ever met.

"Well, I'll go and have a look. What will she do?"

At the end of the speech, Xiao Yiyuan puts on the clothes that he has taken off to his waist. In the persuasion of the doctor, he leaves the room and goes to the autopsy room.

"Guard Lu, if you don't cherish your body any more, the wound will get worse. You have to persuade him..."

Seeing that he couldn't persuade Xiao Yiyuan, he aimed at Lu Hua and made a long argument.

……

In the autopsy room, Xia Jin lit a candle and shaved off all the hair on the head of zhugehong's corpse with a razor. Then she held a candlestick in one hand and turned over the head of the corpse in the other, carefully observing whether there was a sharp object penetrating into the top of the head.

For a long time, she really found a sign in the dingmen acupoint that was easy to be ignored.

At this acupoint, there is a hole which is hard to see with naked eyes.

Under the illumination of candlelight, press your scalp with your hand and observe carefully. You can see that there is a slight silver reflection in the small hole.

The brain is the most powerful and vulnerable part of a person.

Xia Jin felt that she was getting closer to the truth of Zhuge Hong's death.

She used a scalpel to cut the scalp at the small hole and found that the silver light was a small needle like object less than one millimeter long, similar to a silver needle.

And the other part of it is in the skull, in the skeleton.

Xia Jin tried to draw the needle directly by hand, but failed.

This makes her difficult. The hardness of the human head is between five and six, and the normal bearing capacity is between 200 and 500 kg.

In this world, there is no electric craniotomy device and no craniotomy saw. It's impossible to open a skull to get things. Does she have to make a craniotomy saw?

"What are you doing?"

Suddenly, there was a deep voice behind him.

"Ah..."

Xia Jin, who is thinking hard, is interrupted by this sound. It happens that there is a dark wind blowing outside, which is strange and chilly everywhere. She is scared to let go of the corpse's head and jump away.

The candle flickered in the cold wind, and the light and shadow in the room were bright and dark.

Xia Jin suppresses her horror and looks at the sound source. When she sees Xiao Yiyuan's face in a silver and white robe, she smiles and feels

"Lord Yi, I don't know what you did when you came here so late?"

"How can I sit back and watch you work so hard to investigate the case?"

He would never tell her that he was worried that she was here alone at night.

"Mr. Wang, you have to coordinate the overall situation. You are different from me."

Xia Jin continues her fake smile.

Xiao Yiyuan put her reaction into his eyes and said quietly:

"What do you find?"

"I found something similar to a silver needle at its dingmen point, but there was no craniotomy tool to take it out for further verification."

When it comes to business, Xia Jin gathers a fake smile on her face and corrects herself.

You want to cut your head open?

Xiao Yi's deep eyes flashed a touch of surprise color very quickly.

He stepped forward, held his breath, and looked at the corpse's head with the help of the light of the candle.

The scalp was cut off bloody, even terrible, and in that piece of blood, Xiao Yiyuan acutely caught a touch of silver.

"You stand back for a while."

Xiao Yiyuan stares at the corpse's head, but his words are to Xia Jin.

Xia Jin didn't know what he was going to do, but she took a few steps back.

In her doubts, Xiao Yiyuan moves to the foot of the corpse and secretly gathers his internal power in his palms.

The next moment, his two palms suddenly patted the body's feet, and the candle fire in the room was windless.

At the same time, the needle like object in the corpse's head suddenly shot out under the impetus of huge internal force, carrying a strong internal force, smashed the basin in front of the corpse's head and fell to the ground.

After the initial surprise, Xia Jin quickly steps forward to pick it up and places it beside the candle to observe.

This is a thin spiral needle. The part inserted into the skull adheres to a layer of burnt yellow substance.

The outer part of the skull, however, showed no sign of this, and it glowed silver under the light of pondering.

She rubbed a little burnt yellow substance with her hand and found that it was actually the brain of a human being exposed to high temperature.

This thing into the brain is bound to die, not to mention in the case of high temperature?

At this point, Xia Jin determined that zhugehong's death was caused by this acupuncture.

As for the dead only facial pain symptoms, the rest of the body parts are no different reasons, Xia Jin thought, maybe only catch the murderer, can reveal!

Thinking of this, she could not help but frown. How much hatred could make people take their lives by such cruel and terrible means as spiral needle into the brain?

On one side, Xiao Yiyuan saw that Xia Jin had not moved for a long time and went forward to see what she had in her hands.

When he saw the screw bone penetrating needle clearly, Xiao Yiyuan's pupil shrank and his deep eyes were full of shock.

"How could it be?"

The method of making and using spiral bone penetrating needle has long been lost.

How could zhugehong die of spiral bone penetrating needle?

What does Zhou Boyi have to do with this?

"Lord Yi, have you found something?"

Xia Jin see Xiao Yiyuan come to take incredible, seems to know what, careful to ask.

"This is a spiral bone penetrating needle, which is unique to the Shang family in Mobei. Once it enters the body, it will be difficult to save Da Luo Jinxian in this world. Apart from the Shang clan, no one will make and use it any more... But as early as 16 years ago, the Shang clan was slaughtered by the Youming house. "

Xiao Yiyuan has a cold face and a deep breath, which seems to be related to the Shang family.

"If so, now there are two possibilities. One is that some businessmen are still alive, and the other is that the method of making and using spiral bone penetrating needle has been stolen."

Xia Jin did not go deep into the changes of Xiao Yiyuan and continued:

"But no matter what the possibility is, now that the cause of Zhuge Hong's death has been determined, we can bury him with his wife and children. When Zhou Boyi is cleared up, we can find out who killed him. It can also be regarded as an account for him and Zhuge Yuqi. What do you think of the king?"

Zhou Boyi sent troops to kill Zhuge manmen, but Zhuge Hong, who was the first to bear the brunt of the massacre, did not die by the sword, and the Zhuge people were poisoned by arsenic to get rid of Zhuge Hong.

"I suspect that there are two groups of people who are thinking about Zhuge's idea, but now it is the first thing to deal with Zhou Boyi. As for the one who is related to the screw bone penetrating needle, I will check it later."

Xiao Yiyuan thought for a long time, collected the evil spirit of his whole body, nodded slightly, his thin lips wriggled, and his voice was cool.

His hand hidden in the sleeve robe slowly tightened, hard into a fist, dark eyes already full of storm.

The young master of the merchant was very kind to him, which was one of the reasons why he never dealt with Bai Lihong, who was not strict with the emperor.

The appearance of spiral bone penetrating needle aroused Xiao Yiyuan's hatred again.
