Zhao Da's cheeks twitched for a moment, and then he gritted his teeth and said, "It's not good to run anywhere, you have to run in front of grandpa!" ”

Zhang Heiniu rode his horse to follow, looked at the human figure full of arrows in front of him, and said with a smile: "Zhao Da, you dare to kill people, I admit defeat." ”

Zhao Da's face turned dark.

A moment later, Chu He, Song Nian and others also arrived.

I saw that the man's left hand was forward, his right hand was pressed under him, and he crawled to the ground, and his back was hit by seven or eight arrows like a flower, and the ground on both sides of his body was stained red with blood.

Lin Lao glanced at it, and shook his head slightly: "It's the border army!" ”

Although this person was wearing a robe, so it was also civilian clothing, but there was a striking tattoo on the back of his left hand stretched forward

"Shu, Ding Yi, three thousand two hundred and seventy-five".

This is the "number" of this person in the border army.

Lin Lao was familiar with this kind of numbering system, so he could tell at a glance that this person was a border soldier.

This numbering ...... But there is no black armor.

Mistakenly killed by the border army...... This is really a big and small thing.

Lin Lao coughed: "My lord, Zhao Da is also an unintentional mistake. What's more, we need the help of the border army to find clues outside the fortress. Therefore, this matter must also be strictly ordered not to be spread to the outside world, so as not to let the border army learn about this matter and cause complications. ”

Song Nian smiled: "Old Lin, I don't agree with what you say. This person has a great stake, but he must inform the border army. ”

Zhao Da glared at Song Nian angrily: "Master Song, I killed this person by mistake, my life is not a pity, just use my life to resist my life!" But tell the border army that it's going to be a bad thing for adults! ”

After all, Zhao Da actually took out a knife and put it on his neck, ready to apologize for his crimes!

"Put down the knife!" Song Nian shouted angrily.

Zhao Da was stunned for a moment, but was taken away by Zhang Heiniu.

"You didn't kill people, why are you in such a hurry to die?" Song Nian stretched out his hand and lifted the robe: "Your bow and arrow are so weak, after piercing the robe, it just pierced this person's skin." ”

"Where is the strength of my bow weak......" Although Zhao Da was not convinced, after opening the robe, he could see that the arrow only penetrated the robe, and only half of the arrow revealed the robe.

This kind of injury is definitely not enough to kill a person. That is, the bleeding looks scary, and the blood flows along the sides of the corpse, but it is not fatal.

"And what was the cause of death?" Chu He also squatted down to check.

"The cause of death is most likely hunger, thirst, dehydration, and lack of electricity...... Lack of salt, and then suddenly encountered Zhao Dazhu's shot, and his heart stopped beating and died. Song Nian almost said that it was a lack of electrolytes, but he temporarily remembered that there was no such word in this era, or that it was easier to understand the lack of salt.

"Lack of salt?" Chu He frowned.

Song Nian reversed the corpse: "You see, the corpse's lips are dry, the skin of the mouth is seriously peeled off, and there are salt spots hidden on the skin, obviously it is a long journey and sweating, which has led to a large loss of salt in the body. The lack of salt will make the human heart weak, and at this time, forcibly running, encountering fright, can easily trigger cardiac arrest. ”

"In other words, it was the lack of salt that caused the frightened death?" Chu He frowned, very puzzled.

"Hey, you've always heard the allusion to the frightened bird."

The allusion of the frightened bird is also spread in this land, and Song Nian can only use this allusion to make Chu He understand the matter of "scared to death".

"But...... Lord Song, this person obviously carries salt water with him. How to go back to dehydration and desalination and die? Zhang Heiniu poked a bamboo tube on the soldier's body with Zhao Da's steel knife, and there was a faint sound of rattling inside.

"Take salt water with you?" Song Nian took off the bamboo tube and tasted it, and sure enough, there was a slight salty taste.

"I'm annoyed, autopsy! You all dodge. ”

Damn, how can you carry this thing with you in this era? The ancients should not be so smart!

The others immediately dodged away, leaving the open space for Song Nian.

This time, Song Nian learned a lesson, honestly took off the clothes and accessories on the corpse, and then began to observe.

The corpse's mouth and nose were slightly blackened, possibly poisoning or lack of oxygen.

The chest and abdomen of the corpse and the north are crisscrossed with diamond-shaped patterns.

……

The corpse had calluses on both its left and right hands, and there were scars on the palms.

……

The corpse's clothes looked tattered, but in fact the workmanship was extremely thick, and it was made of high-quality fabric, deliberately made of civilian style.

……

The corpse carried dry rations, gold nuggets, broken silver, and an oiled paper bag in its arms.

……

The corpse's legs were slightly spread in a slight arc, and the muscles of the legs were strong and the pressure was strong.

……

On the back of the corpse, there is a gold sore medicine, and when the gold sore medicine is scraped open, a scar that has just begun to heal can be seen, and the wound is diamond-shaped.

After fully absorbing this information, scenes began to form in Song Nian's mind.

The frontier army, good at archery, riding horses for a long time, good at running, wearing a coat, carrying salt water, dry food, and gold and silver fragments in his arms...... and wax paper wraps.

Song Nian took a deep breath, sorted out the conjectures and ideas in his mind, and said slowly: "This person should be an elite of the border army, good at riding and shooting, experienced in long-distance travel, and able to use salt water and other things to replenish physical fitness. After disguising himself, he stalked in the wilderness away from the avenue in order to pass on classified information. ”

Chu He thought for a moment and nodded slightly: "Then why did you appear here?" ”

Song Nian pointed to the arrow wound on this person's body and said: "This person should have been ambushed in the wild, and after being hit by an arrow, in order to get rid of the tracking and change the route, he happened to meet Zhao Da Hunting at the valley mouth. ”

"What about the cause of death?"

"The cause of death? I have a few guesses, but I can't confirm until after the dissection. ”

Song Nian slowly dissected the person, and after a while, she put down the scalpel and sighed: "The cause of death ...... Got it. ”

In the stomach of the deceased, in the gastric juice, there was a pill that dissolved a small half. Song Nian tested the silver nugget in his arms, and sure enough, it was black and had sulfide.

"Suicide, death by poisoning! The poison should be arsenic. ”

Unpurified arsenic is often mixed with sulfides, so suspected poisons can be easily tested with silver needles.

"Suicide?" Chu He frowned: "Why did you commit suicide?" ”

Song Nian smiled: "Since he acted secretly, and in the territory, he didn't dare to act as a border army, but hid in the wilderness, he must have a big secret, at this time, he was suddenly shot by Zhao Dazhu's arrow, and under the fright, he thought that he was discovered by the enemy, so he swallowed the poison directly." ”

"There is some truth in this, but where is the thing that is transmitted?"

Song Nian was confident: "Maybe it's not a letter or an item that is being delivered, but a ...... Messages and the like, so that when a person dies, the lights go out, and nothing goes wrong. ”

"This kind of thing...... Unheard. Suddenly someone came to deliver a message, and it was difficult to distinguish the authenticity from the false. Chu He was a little unbelieving, which was inconsistent with what he knew about the secret message in the army.

Song Nian opened the oil-paper bag with a smile: "Look, there is nothing in this oil-paper bag, but I'm afraid it's also a trick." ”
