Li Bing raised his wrist and looked at his watch, which happened to point to five o'clock in the morning. He was surprised to find that above the Seven Star Cave, at dawn, there were indeed the Big Dipper hanging on it.

Seeing Li Bing raise his head and show a look of surprise, everyone also looked at the sky. Zhang Yuanshan was secretly shocked in his heart, in this mountainous area, the Big Dipper was so clear and bright.

Li Bing muttered: "It seems that He Jie really didn't talk nonsense, he really looked up at the entrance of the cave and saw the Big Dipper and named this cave the Seven Star Cave." ”

Zhao Wan'er said curiously: "Li Bing, why is one of the seven stars of the Big Dipper relatively faint?" ”

Li Bing smiled and said, "Speaking of which, you'd better ask Brother Zhang." Reading astronomy and knowing geography are the basic skills of Taoist priests. ”

Zhang Yuanshan said happily: "Tianshu, Tianxuan, Tianji, Tianquan, the four stars form the doukui; Yuheng, Kaiyang, Yaoguang, and three stars form the bucket handle. Among the seven stars of the Big Dipper, the luminosity of the heavenly power is the darkest, but it is the place where the top handle meets, and it is the most important. The two stars Tianshu and Tianquan form a bucket, and the line of the two stars points to the North Star. ”

After Zhang Yuanshan finished speaking, he looked at it carefully again, and sighed: "Wan'er, you see that the six stars are very bright, and the darkest one is the core Tianquan Star of the Big Dipper." It's just a pity that there seems to be a thin layer of clouds covering the place of Polaris, which obscures the already bright Polaris. ”

Zhao Wan'er had a whim, and grinned: "The cartoon images of the stars are all five horns, so will it represent the five of us?" ”

When Li Bing heard this, his face changed, and he suddenly looked up to the sky and laughed: "I understand, Wan'er, thank you, it can really be said that you woke up a dreamer with a word!" ”

This time it was Zhao Wan'er's turn to be surprised, and she looked at Li Bing puzzled. Li Bing pointed to the sky and said, "Do you see the North Star?" What Wan'er just said was so interesting that I suddenly realized that the position of the five of us was secretly in line with the North Star. And the North Star is dim at this time, symbolizing that we still have mysteries to solve and are in a state of confusion. ”

"The Big Dipper, the six shining stars, correspond to He Jie and his five classmates. And the most critical Tianquan Star is relatively dim, undertaking the Dou Kui and the Bucket Handle. If the Big Dipper is vividly compared to a Tiangang Beidou Formation, then this Tianquan Star is the key point of the Tiangang Beidou Formation. ”

"It is the core of this formation, although it is inconspicuous and seems to be hidden in the shadows, but the other six stars are all at his disposal. Do you see what I mean? He Jie and his five classmates are dead, six of the Big Dipper have returned to their positions, and Tianquan Star is still looming, indicating that we have not yet found the real murderer, and this murderer corresponds to Tianquan Xing. ”

As soon as Li Bing's words came out, everyone exclaimed. Shi Liya's face changed suddenly, she groaned for a while, and said in a trembling voice: "Li Bing, it is impossible for there to be a murderer among the five of us, could it be that this Tianquan Star refers to Officer Huang?" ”

Li Bing thought for a while and said, "Don't worry, let me think about it, I also suddenly found Officer Huang's suspicions." By the way, why don't we speculate that if Officer Huang is the murderer, how did he kill He Jie and his five classmates? ”

Zhao Wan'er said suspiciously: "Li Bing, you are a bit outrageous, right?" How could Officer Huang be the murderer? ”

Li Bing said solemnly: "Wan'er, don't be emotional. We're just assuming it now, and we're not sure that Officer Huang is the murderer. ”

Zhao Wan'er nodded at this time and motioned for Li Bing to continue. Li Bing pondered for a while and said, "First of all, assuming that Officer Huang is the murderer, what is his motive for killing He Jie and his five classmates?" ”

Shi Liya continued: "Li Bing, I think the real motive for Huang Shengjie's murder is aimed at He Jie, after all, he and He Jie's five classmates have never known each other, so there is no need to kill them. ”

Zhao Wan'er retorted: "This doesn't seem to make sense, right? You have forgotten that when we arrived at Xiaohuangzhuang on the first day, we were forced to stay in a small hotel opened by Sanniang due to a flash flood. Didn't Sanniang talk about He Jie and Huang Shengjie? ”

Sanniang said that they were talented people in Xiaohuangzhuang, He Jie was admitted to university, and Huang Shengjie became a policeman. Although the two families originally had a good relationship, so they jointly built a house with the same format on the hillside west of the village, but later the two families became enemies because of trivial matters. ”

However, with Huang Shengjie's parents falling off a cliff and dying at the same time, He Jie and Huang Shengjie have already abandoned the grievances of the previous generation and become good friends again! He had no reason to kill He Jie! ”

Li Bing said: "Wan'er, it's hard to say this. There is a good saying, 'A gentleman takes revenge, ten years is not too late', maybe Huang Shengjie is scheming and the city is deep, he secretly has a deep hatred with He Jie, and he is friendly with He Jie, just to find an opportunity to kill He Jie without letting others suspect him? ”

Zhao Wan'er was speechless for a while, and nodded thoughtfully. Li Bing continued: "Of course, no one knows the real reason why Huang Shengjie killed He Jie, unless he can say it himself. Now, let's put aside the unknown motive for the killing, and deduce how he killed the six people. ”

Shi Liya smiled strangely and said, "Li Bing, you now treat yourself as Huang Shengjie, and you want to kill He Jie." If you think about it from his point of view, isn't it easy to deduce? ”

Li Bing nodded, thought for a moment, and said, "I have to speculate on everything together to be able to solve these mysteries." Think about it first, when Huang Shengjie found He Jie's body yesterday, we all thought that He Jie committed suicide by jumping off a cliff, after all, he left a suicide note. ”

"Now inspired by the Big Dipper, we assume that He Jie killed rather than committed suicide. So, how did Huang Shengjie kill him? It must have pushed him off a cliff. And why didn't He Jie resist? I wonder if Huang Shengjie had already controlled He Jie on the night of He Jie's disappearance, and hid He Jie under the cliff of the big rock, so we didn't find any trace of He Jie when we searched the mountain. ”

Shi Liya said: "Li Bing, I'll cooperate with you." I ask questions, as long as you can answer them, then step by step extrapolation, the truth will not be far away. ”

Li Bing nodded, Shi Liya thought for a while and said, "Li Bing, if I am He Jie, even if I am subdued by you, how can you hide me under the cliff and not let others find out?" Aren't you afraid that I will call for help and run away? ”

Li Bing said: "This question is very critical, but it also solves a little doubt in my heart. When I found He Jie's body yesterday, I wondered why He Jie had a few bruises on his wrists and ankles. Now I've figured it all out. ”

"I think Huang Shengjie must have tied He Jie's hands and feet with ropes, so that He Jie lost the ability to break free and escape! As for why he didn't shout, it was because he had something stuffed in his mouth and couldn't scream at all. ”
