"Hmm, is there a problem with that?"

Song Yi felt a little embarrassed, he naturally didn't know how the original Song Yi had spent the past four years, but combined with everyone's reactions before, that Song Yi was a cold young master before.

"It's okay, it seems that going through life and death has also made you think about a lot of things, people always have to come out of the shadows. Song Yuqing didn't bother with Song Yi's affairs at this time, she directly thought that Song Yi came out of the shadow of her mother's accidental death, which was a good thing: "In short, it's good that you are safe and sound." ”

"By the way, have you found out who did it?" Song Yuqing is most concerned about this issue now, she must know who dares to make such a death attack on her younger brother, if the other party is someone outside the Song family, then as long as you know the identity of the other party, then Song Yuqing will definitely make that person's death ugly.

"Looking. Song Yi said, then turned around and walked to the table in the middle of the room, and poured a glass of water for Song Yuqing: "Sit down and rest for a while, drink saliva." ”

"Oh. Song Yuqing didn't know what Song Yi meant by what she was looking for, she reached out and took the cup handed by Song Yi, and immediately sat down at the table, although Song Yi suddenly became so sensible that she was a little uncomfortable, but this was a good thing after all, so she didn't think much about it.

"It's such a nice day that the windows should all be open for ventilation. Song Yi walked to each window and opened the three windows in turn, especially the south-facing window that had been sealed for a long time, and when Song Yi pushed it open, it really shook off a cloud of dust.

And seeing Song Yi open that window, Song Yuqing also had a touch of complexity in her eyes, and she sighed: "Since my mother left four years ago, you have never opened that window, I remember that in the past, every late at night, my mother would see if you had rested from that window." ”

Hearing what Song Yuqing said, Song Yi understood the strange feeling in his heart just now, no wonder this window was closed for so long, it seems that with the unexpected death of their mother, it was the original Song Yi who also suffered a big blow, psychologically speaking, people who had a close relationship with the deceased, through the places that the deceased had been to before his death, the things he used, and the words he had said, these things could easily make others evoke some memories of the deceased even after many years.

For the original Song Yi, when he saw this window, he would think of his mother-in-law coming to visit him every night, but the deceased was no longer there, even if Song Yi looked forward to his mother-in-law standing there again, it was already impossible, so he closed that window from then on.

In this regard, Song Yi also didn't want to expand this topic in front of Song Yuqing, after he opened the window, he looked out of each window, and the ground outside was not covered with mud, but a uniform layer of sand and gravel.

"Sister, is there a layer of sand and gravel like this in the courtyard of our Song family?" Song Yi looked at the sand and gravel outside the house, and asked Song Yuqing behind him.

"I shouldn't have paid much attention to this kind of thing, what's wrong?" Song Yuqing replied when she heard this.

"I just want to know where this dirt came from?" Song Yi stretched out his fingers, picked the little bit of dirt off the second window frame with his fingernails, and put it to his nose and sniffed it.

"Dirt?" Song Yuqing frowned, and immediately put down the cup in his hand and stepped forward, while Song Yi also moved the dirty dirt on his fingers in front of him.

"Whew... It's dirty. Seeing the dirt on Song Yi's fingers, as a girl who loves cleanliness, Song Yuqing felt that she was a little unacceptable.

Song Yi naturally has no such scruples, as a person who often watches the corpses of all kinds of decaying maggots, even if this is a piece of, he will not feel anything.

"The man who wanted to assassinate me came in through this window, it must have been the dirt on his shoes, and he had been hiding in this room before I returned. Song Yi pointed to the roof beam: "I just looked at it, and there are indeed some traces of dirt, which have not yet dried up, and they were left last night." ”

Song Yuqing was stunned for a moment, she didn't expect Song Yi to start investigating the assassin by herself, and she could analyze it through these clues, this is bluffing herself by saying a few random words, right?

"I'll have to go outside. Song Yi walked outside the house, and on the gravel floor outside, he slowly lay down, his eagle-like gaze constantly sweeping over the sand and gravel spread on the ground.

If it were an ordinary person who came to see it, he would sweep his gaze at random and find nothing, but what Song Yi did was not a simple look, but an almost subtle observation, he almost put his face on the ground, and as he expected, as long as he looked closely, these gray-white sand and gravel were covered with all kinds of mud everywhere.

Sniff!

Song Yuqing, who was not far away, saw Song Yi sniffing around on the ground like a dog, and was stunned again, could it be that last night's incident was too exciting for Song Yi? This is the rhythm of going crazy?

"Sister, do me a favor. When Song Yuqing was stunned, Song Yi, who was lying on the ground, suddenly turned his head and said to her.

"What... What?" Song Yuqing came back from her shock, and she immediately said, "What are you doing? ”

"Go and help me find some leaves, or just break a branch and bring more leaves. Song Yi ignored Song Yuqing's words, and after speaking, he turned his head again, carefully looking for all kinds of subtle traces on the gravel ground, and Song Yuqing hesitated for a moment, but really did what Song Yi asked, she walked to a big tree not far away, the lotus step moved slightly, the jade hand was held on the hilt of the sword behind her, and in the next moment, with a cold light passing by, a branch above fell into Song Yuqing's hand.

Holding this branch with more than a dozen leaves, Song Yuqing handed it to Song Yi.

"Thank you, and then you step back a little bit so as not to spoil the scene. Song Yi took the branch and waved his hand to Song Yuqing.

"What are you going to do?" Song Yuqing looked at the 'abnormal' Song Yi, and suddenly didn't know what to do, perhaps out of curiosity, she was suddenly curious about what Song Yi was going to do.

Song Yi's eyes were focused on the gravel floor in front of him, and after remembering the smell of dirt at the window earlier, all he had to do was to find the same traces of dirt here, provided that the assassin had indeed walked through here, of course.

This kind of on-site investigation has often been done by Wang Hanyuan before, using the principle of material exchange in criminal investigation, which roughly means that as long as two objects are in contact, then there will be an exchange of materials between each other, more or less, just like two cars collide, then on the contact surface, some paint on the surface of a car will definitely fall on another car, and the same is true after a person is hit, and there will definitely be paint or other things belonging to the car will be found in clothes or a certain part of the body.

Through this principle, Song Yi believes that as long as the assassin walks here, then the shoes with dirt under his feet will definitely exchange with this gravel field, and the soil will stay here, and some sand and gravel will also remain at the bottom of that shoes.

However, there must be a lot of people who have walked here, so the dirt or other things left behind will also be divided into many categories, and because of this, Song Yi has to write down the smell of dirt on the window, and then look for it on the ground, which is very troublesome, and the human nose does not necessarily have this ability.

But soon, Song Yi was pleasantly surprised to find that the people of this world seemed to be stronger than the people on the earth in terms of their five senses, and as Song Yi expected, when he searched for a few minutes on the gravel outside the window, he found a piece of sand and gravel stained with a small mud mark, he picked it up and sniffed it, and determined that the smell was basically the same as the soil on the window.

"Sure enough. Song Yi smiled slightly, finding these subtle traces of dirt went more smoothly than he expected, and he immediately found another place about a foot away that was stained with the same smell.

But Song Yi didn't touch the dirt, he plucked a leaf from the branch and inserted it in the coordinate point where the soil was found, and the previous discovery gave him more confidence, and he believed that it was only a matter of time before he restored the assassin's path outside the house.

Song Yuqing, who was not far away, watched with a depressed face as Song Yi inserted those leaves on the gravel ground one after another, but soon, when she saw that more than a dozen leaves planted by Song Yi formed a continuous route and connected to the location of the window pointed out by Song Yi, a conjecture appeared in Song Yuqing's mind.

Could this be the path taken by the assassins?

"There aren't enough leaves, go find some more. When Song Yuqing was surprised that Song Yi was able to restore the assassin's path in this way, Song Yi's voice suddenly came, and Song Yuqing saw that the leaves of the branches in Song Yi's hands had been used up.

"Oh... Good. Song Yuqing immediately set off to intercept new branches, and this time the branches she brought were several meters long, the main trunk was as thick as an arm, and there were countless leaves on it, which made Song Yi speechless for a while, and Song Yuqing's support was a little too much.

Not only that, Song Yuqing also kept helping Song Yi pick those leaves, fold them into a stack and send them forward, which also saved Song Yi a lot of trouble.

"Thank you. ”

After getting more leaves, Song Yi immediately continued his search, taking advantage of the fact that the smell he remembered had not completely faded, he walked slowly, and as soon as he found the trace, he inserted a leaf, and he soon found that this path did not lead directly to the house where he was, there was a bend along the way, like the 'unknown person' hesitated, but he finally made a move.

"Yi'er, what are you doing?" A familiar voice suddenly came, Song Yi raised his head, and found that Song Qing had appeared in front of him at some point.

Song Yuqing, who was not far away, saw Song Qing coming, and also stepped forward quickly: "Dad, are you here? Don't stand there yet, it may disturb the traces." ”

"Disturbing traces, what traces?" Song Qing was as inexplicable as Song Yuqing at the beginning, he saw his son make such a strange move, and suddenly there was an indescribable collapse in his heart, which was... If you let the rest of the Ming Hall and the Song family see it, what will it become?

Could it be that what happened late last night left Song Yi mentally traumatized?

"Dad, Xiao Yi didn't know where he learned a magical method, he was able to find the path taken by the person who assassinated him. Song Yuqing saw that Song Yi was busy, so she explained to Song Qing on his behalf.

"No, does he look too much like that?" Song Qing really couldn't accept that his son was crawling on the ground like a dog.

"Dad, stand back for a moment. Song Yi didn't care what other people thought at all, even if the other party was his father, he continued to bury his head in the search for traces of dirt.

"Can you really find the way with this method?How come I've never heard of it?" Song Qing still didn't believe that Song Yi had a way to do such a thing.

"Dad, look here. Song Yuqing pulled Song Qing and led him to the gravel ground marked by Song Yi with leaves, basically each leaf represents a footprint left by the assassin there, and when these leaves are connected, it becomes a path to the window of Song Yi's house.

Song Qing was still surprised when he saw this path, he took a few steps forward, looked inside the house from the window, and looked back at the path outlined with leaves behind him, although he didn't know if this path was real, but if he followed this route, it was indeed possible to assassinate Song Yi in the middle of the night.

"Huh, isn't that Young Master Song Yi?"

"What is he doing lying on the ground?"

"What's wrong with him?"

Song Qing and Song Yuqing's most reluctant situation finally appeared, as the length of Song Yi's restoration route extended to other rooms, some people from the Ming Hall and the Song family who passed by discovered Song Yi's strange behavior, especially those teenagers and girls, they knew Song Yi's identity.

Dignified young master, how did you become like this?
