"Why?" Cheng Luojie asked in surprise.

Leng Yi beckoned her to follow her and returned to the courtyard. Walk to a house next to the collapsed upper room, this house has the same frame structure as the upper room, the difference between the two is the rooms and furnishings inside. Leng Yi pointed to the same short beam on the side of the gable and said, "You imagine this as the beam of the upper house that collapsed, and then look at it, what's the problem?" ”

Cheng Luojie looked here and there, and said, "There's no problem, it's the same." ”

"I mean, if you shoot an arrow from the place you just found outside the wall, you can shoot it here. Will it work? ”

Cheng Luojie looked at it several times and said, "There's no problem!" ”

Leng Yi observed, asked the man to bring two wooden ladders, and on the opposite side of the gable of this house, at a distance of about a distance, the two ladders intersected, and then said to Cheng Luojie: "You go up the ladder, shoot an arrow at a height about the same height as that wall." ”

Cheng Luojie smiled: "Are you testing me?" Piece of cake! - Bring a bow and arrows! ”

The archer caught Wei Du and hurriedly fetched a bow and arrow for her. Cheng Luojie steadily got on the ladder on the opposite side, opened her bow, didn't even aim, and directly released an arrow.

The arrow was like a meteor, and with a thud, it hit the short beam.

Cheng Luojie said triumphantly to Leng Yi: "How? ”

Leng Yi glanced at it, shook his head and said, "The landing point of your arrow is several inches lower than the hole in the short beam of the upper room. I want to shoot to the same height! ”

"What's so hard about that!" Cheng Luojie opened her bow again, but this time, her bow kept pulling, but it didn't shoot. It took a long pause before finally letting go of the strings.

Sou!

The arrow flew out, but it hit the eaves with a bang! A tile was shot to pieces, and the shaft of the arrow was stuck in the eaves.

Cheng Luojie was a little embarrassed and said, "The eaves are blocked." Can't shoot there. ”

Leng Yi said: "That's right, you finally found the problem!" - The flight of the bow and arrow is an arc, and the farther the distance, the greater the arc. At such a distance, the bow and arrow could only fly in a relatively large arc. However, the short beam is behind the eaves, and although the arrow can be seen from a straight distance, the arrow cannot be shot because the eaves are blocked in front. Therefore, the distance of the arrow cannot be so far, and the murderer did not fire the arrow outside the wall. ”

Cheng Luojie nodded: "That's right, my arm strength is already very large, I can't do it, and the murderer can't do it." The place where the archery is shot is not outside the yard. Since it's not outside the courtyard, it means that the murderer is someone from our post station! Otherwise, he wouldn't have had to do it. ”

"Yes, I want to cover up, but I show my feet." Leng Yi said, "We need to find a location to determine where the murderer fired the arrows from." ”

Cheng Luojie carefully searched the open space on the side of the gable of the collapsed upper house, imagining in her mind how the murderer shot this fatal arrow. Finally, she shook her head and said, "I can't think of it, it's an open space, and judging from the archery line shown by the shaft, it's about the same as the wall, at least two people high." Even if he jumped on the spot, it would be difficult to reach such a height and release an arrow! ”

Leng Yi touched his short beard, pondered for a moment, and said, "I can't jump so high, can I use other ways to make myself taller?" It's like we're using two ladders to put together. Of course, he would not take a ladder, because the archery burned the rope, which was very short, and the target of the ladder was too large, and it was placed in the firewood room, so it was easy to be seen. Therefore, he should have used some other method to take off the air and reach altitude and then release the arrow. ”

As he spoke, Leng Yi lowered his head and searched on the ground. The ground of the inn was clean, and the guys had already swept the snow aside. Next to the upper house all the way to the fence, there was a clearing, the snow had been swept away, and the ground was paved with green bricks, so there was no trace left.

Cheng Luojie said: "It doesn't matter what method they shoot, just pull him out, he will confess himself." ”

"Then have you figured out how to find this murderer?"

Cheng Luojie was a little embarrassed and said, "I don't have a clue now." ”

Leng Yi said: "You are the head catcher from the six gates of the capital, you should have a hand in solving the case, you can't be too modest, I asked you to study this case with me, I just want to hear your opinion." ”

Cheng Luojie thought for a while and said, "Then I'll tell you my opinion, I think that this case, since it is determined that it was done by insiders, then find it from insiders." This person will definitely shoot arrows, and besides, the archery skills should be not bad. Otherwise, it is really difficult for ordinary people who have not been trained in archery to shoot a rope with a rocket, or to shoot the bottom of the rope. - Among our six entourage, only Xu Feng and Wei Du are archers, and not all four women are archers. Of course, my sister and I, as well as Yin Ying, will naturally do. The hunter must have been able to do it, and the three officers and soldiers, two of whom were archers, would also be able to. ”

"Well, at the moment, there are six people who can shoot arrows, not counting the people at the station. We need to narrow it down further. ”

Cheng Luojie said: "How can this be reduced?" ”

"Think about what else is impossible, that is, the murderer cannot have, such as the time of the crime. Not just the time to shoot arrows, but also the time to saw the beams......"

Cheng Luojie said: "I know! Such a thick beam, to be sawn, at least a meal, and Huang Mei, Lin Ling, the three of us, followed the eldest master you hunting in the mountains, and when we returned to the post station, we have been busy barbecuing, and the two of us have no time for this meal. Therefore, because the two of them did not have the time to commit the crime, they could be ruled out. ”

Leng Yi muttered: "We live in this Yinshan Inn, it was decided temporarily, and besides, this post station has three upper rooms, and I will only know which one to start in after I determine which one to live in." The murderer could not have known the layout of the matter, sawing off the beam. Therefore, the murderer should have waited until we stayed in the inn and determined which room I was in before sawing wood, so it seems that the time of sawing wood was from the time we confirmed that we lived in the Yinshan Inn and determined that I lived in that house until it collapsed. Your two deputies, Huang Mei and Lin Ling, have no time to commit the crime, so they can be ruled out. ”

Cheng Luojie said: "Master Dong and the guys at the post station don't know how to shoot arrows, so they can also be ruled out." ”

"Then we have to find evidence that they don't know how to shoot arrows."

"This is easy to do, I will call them all out later, and each person will know how many arrows to shoot, and those who can shoot arrows can see this action at a glance."

"Okay, for the time being, it is assumed that they don't know how to shoot arrows, and they can all be ruled out. - Who else can rule out? ”

"My sister Cheng Luoyan can also be discharged. There's no way she's going to murder you. ”

"Why?"

"Because she's my sister, I know her very well."

Leng Yi smiled, it is true that the twins have an inexplicable spiritual connection, but this cannot be a reason to rule out criminal suspicion. Leng Yi smiled and said: "I believe in your feelings, but this is how it is to solve the case, you can't talk about feelings, you must eliminate them one by one, and the reasons for being eliminated can only rely on alibi or evidence that it is impossible to commit a crime." Therefore, your sister cannot be ruled out as a suspect for the time being. ”

Cheng Luojie said: "Okay then." After this was ruled out, the only suspects were Yin Eagle and his remaining entourage to capture Wei Du, and my sister and her two entourages to capture Zheng Yan and Li Fen. Then there was the hunter and the two messenger guards. - I think the focus should be on the hunter. A hunter, going up to the mountains to hunt, what kind of post station does he live, this alone is doubtful! ”

Leng Yi said: "What you said has some truth, okay, then let's go our separate ways, you go and eliminate a few of them, and I'll ask the others to make sure they have time to commit crimes." ”

"Okay! However, you'd better ask my sister first, sir. ”

"Why?"

"Because she's my sister, it's inconvenient for me to participate in the inquiry. When you're done asking her, I'm almost done here, so I can come over and help you ask. ”

"That's fine."

Leng Yi asked Cheng Luojie to call his sister Cheng Luojie, and he waited in his room.
