Wang Yuan walked alone on the mountain road, and along the way he kept thinking about the two tree stumps in Liu Industrial Courtyard, when was it cut down? He thought about Professor Zhou's photo and the fact that he got the box before, if someone deliberately arranged it together, then someone must be secretly observing his movements, so he and Xiaoying suddenly appeared in Zhao Cripple's broken house, and someone must be secretly observing all this. But he arranged Qi Zhuang and Zhao Bin's counter-reconnaissance and did not seem to find anyone's existence. On the contrary, without anyone's prompting, he went to Zhao Cripple, but found two locust trees, which shows that it may be as Xiaoying said, the previous thing was that he thought about it too much, but these two locust trees are definitely not a coincidence, the fragments that his father said in the letter, then there must be some hints, these two locust trees are likely to be the key to finding the fragments.

Wang Yuan went to Liu Shiye's house and found that although the door was not locked, the main gate was locked, Liu Shiye did not come back, and it seemed that he was still at Li Fangzheng's house, and the sun was about to set at this time. Rhubarb found out that Wang had turned out, and ran forward and wagged his tail at him.

"I cooked so much at noon, Uncle Liu must not eat there at night......" Wang Yuan thought to himself.

Wang Yuan saw the two stumps covered by fallen leaves in the southeast corner of the yard, it seemed that Liu Industrial would pile up the fallen leaves there every time he cleaned the yard, as if he was deliberately trying to hide them, the stumps had rotted, and the distance between the two trees was only about two meters, if this was the stump of the locust tree, it should be two big trees before it was cut down.

"There is a locust in the house, which is easy to attract ghosts." Wang Yuan recalled what Zhao Bin said in his mind.

"You kid didn't go back to Li Fangzheng's house to have a good meal, why did you come here to me? I wanted to eat there again. At this time, Liu Xingye walked in from outside.

"Uncle Liu, I have something to ask you." Wang Yuan said.

"What's the matter?"

"What are these two trees?" Wang Yuan asked, pointing to the two tree stumps.

"What's there to ask about the dead tree stump?" Liu Industrial said.

"It's a locust tree, isn't it?"

Liu Shiye's face changed and said, "How do you know?" ”

"When was this cut?" Wang Yuan then asked.

"This was originally in your parents' yard, but when the house was rebuilt, the two trees had been burned to death, and some people in the village said it was unlucky, so they cut it down." Liu Industrial said. "But how do you know it's a locust tree?"

"Look at the stumps."

"Ao~ You still have this ability, amazing, I guess you saw it by looking at the two big locust trees in Li Xuanfeng's courtyard." Liu Industrial said.

"I can't hide anything from you." Wang Yuan said.

"That's right, I've eaten more salt than you kid can eat." After Liu Shiye finished speaking, he called Rhubarb to the house.

"Uncle Liu, next Saturday I'm going to go to the mountains with Professor Zhou to see the square lake, will you go?" Wang Yuan asked.

"What?"

"Uncle Liu, maybe he'll make a big discovery." Wang Yuan said.

"Just let him go alone, what are you going to do with him?" Liu Industrial said.

"Uncle Liu, you should go along, don't you feel bored staying in this old house all day? Or is it ...... Are you afraid of the fire in Yan Shengshan? Wang Yuan said.

"This ...... I'll talk to Li Fangzheng about it. Liu Industrial said.

"If I knew I wouldn't have to come here, then I'll go back to dinner first." Wang Yuan said.

"Wait, don't you want to eat here, stinky boy? It made me run all the way back. Liu Industrial said.

"No, in fact, I'm just here to tell you about entering Yan Shengshan, goodbye Uncle Liu." After Wang Yuan finished speaking, he turned around and ran out quickly.

Liu Xingye stood in the courtyard for a long time and did not return to the house, he looked at the gradually darkening sky and said, "Two locust trees...... This kid is really good......"

That night, Wang Yuan lay in bed and kept thinking about what happened today, as well as the things that Liu Xingye had told him before. When he woke up the next day, Wang Yuan looked at his watch and it was almost ten o'clock, he got up and put on his clothes, and ran out without bothering to brush his teeth and wash his face, he went to the home of Qi Zhuang and Zhao Bin, and found that both of them were not at home, it seemed that the two of them were going to investigate the matter of the locust tree, so he wanted to look for the two of them in the village to see if there was any result.

As soon as Wang Yuan walked to the street, he saw Qi Zhuang being chased by a girl running all over the street: "Qi Zhuang, what are you doing climbing the wall of our house?" This girl is also Wang Yuan's classmate, named Zheng Xinxin.

"Oh, that kid Zhao Bin doesn't know where to go, I'll see if it's at your house." Qi Zhuang said as he ran.

"Did you climb the wall to see? I think you're a scoundrel......"

When Qi Zhuang saw Wang Yuan, he ran over and said, "I don't believe you asked Wang Yuan, we are all looking for Zhao Bin." ”

"Is that so, Wang Yuan?" Zheng Xinxin came over and asked.

Wang Yuan looked at the neighbors around him and came out to see the excitement, smiled awkwardly and said: "Alas, hey, yes, yes, we originally made an appointment to play poker, but Zhao Bin's kid couldn't be found anywhere, so we went to the same school to look for it, but I didn't expect this Qi Dazhuang to save trouble, and actually climbed the wall......"

"So that's the case, Qi Zhuang's weight, it's a blessing that he didn't collapse the wall of my house." Zheng Xinxin said suspiciously after listening to Wang Yuan's words. "Where will Zhao Bin go? Why don't I look for it with you. ”

"No need, I think he must be looking for a place to read again, and we won't look for it anymore." Wang Yuan said.

"Okay then, next time you call me when you play cards, it's boring to be at home on vacation." Zheng Xinxin said.

"Okay, definitely." After speaking, Wang Yuan and Qi Zhuang turned their heads and ran into the alley next to them.

"Alas, she's a sixteen-year-old girl, how can she look like a shrew." Qi Zhuang said.

"You're embarrassed to talk about others, now everyone on the street knows that you took me to climb the wall of Zheng Xinxin's house." Wang Yuan said.

"I was dazzled, I thought his door was locked, I just wanted to climb the wall to see if there were any tree stumps in the yard, who knew that I just saw Zheng Xinxin washing clothes in the yard, and she knocked me down with one shoe." After speaking, Qi Zhuang touched the beaten forehead.

"What about Zhao Bin, where did he go?"

"I don't know, I went to look for him at eight o'clock this morning, and he was gone." Qi Zhuang said. "By the way, Wang Yuan, it only took me a few dozen minutes to go door-to-door to look at the outside, a tree as tall as a locust tree, if there is, you will definitely be able to find it outside the wall. But from my observations, only the old village chief and Zhao Lame are planted in the courtyard. ”

"Really? It seems that I made a mistake in judgment, and there is no reason to cut it down......" Wang Yuan said.

"What the hell is going on?" Qi Zhuang asked.

"I'll tell you the truth, I found a letter left by my parents, because the letter they were afraid of being seen by others, so the letter did not write why they went into Yansheng Mountain, but they said that some clues seemed to be told to many people, I only collected these clues, in order to know the reason why they entered the mountain in the first place, that letter was given to me by the old village chief Li Xuanfeng, in fact, Zhao Cripple should also have some clues, but I didn't get him and was burned to death, but I noticed that they both had two locust trees in their yard, So I was thinking maybe these two locust trees were the clues. ”

"I see, no wonder you were a little unsettled yesterday." Qi Zhuang said. "If the locust tree is a clue, there's really no reason to cut it down......"

"You don't seem surprised that I received the letter?" Wang Yuan said.

"I wouldn't be surprised if anything happened to you, I've always felt like you're the most incredible guy among us, growing up, anything can happen to you as long as you play with you." Qi Zhuang said.

"Really?" Wang Yuan smiled.

"If there's anything you need from our friends, just say it." Qi Zhuang said.

"Let's go to Zhao Bin's house and wait for him, maybe he will find something." Wang Yuan said.

"Well, let's go."

When Wang Yuan and Qi Zhuang rushed to Zhao Bin's house, they found that Zhao Bin was sitting at the door of the house, as if waiting for them.

"How?" Wang Yuan asked.

"I've inquired about it, and there really seems to be a problem here." Zhao Bin said.

"What did you find?" Wang Yuan said.

"Zheng Yang, Li Tieshi." Zhao Bin stared at Wang Yuan and said these two names.

Wang Yuan froze for a moment when he heard these two names, and stood in place without saying a word.

"Judging by your reaction, I will know that the two locust trees you investigated have something to do with your parents." Zhao Bin said.

"I'll tell you more about it later, and you can tell you what you found first." Wang Yuan said.

"Actually, you asked me to investigate the two locust trees with Qi Zhuang yesterday afternoon, and I remembered the two tree stumps in Uncle Liu's yard, but I knew that that place was your parents' old house, so I guessed that it was very likely to be related to your parents." Zhao Bin said. "Your dad used to be medicine pickers in the village with Zheng Yang and Li Tieshi, right."

"Zheng Yang and Li Tiecheng should have no house in the village." Wang Yuan said.

"Actually, we don't need to go door-to-door, and there are not many masons in our village." Zhao Bin said.

"yes, why didn't I think of this method!" Qi Zhuang said.

"The old man Sun Biancai in our village has been a mason all his life, and he has almost participated in the new construction or renovation of houses in our village, so I went to him to ask about it, and he said that there are many flowers and vegetables in the yard of our village, but only those few have planted locust trees, and they have been there for a long time." Zhao Bin said. "Only Zheng Yang, Li Tieshi, Zhao Cripple, Li Xuanfeng and your father's family."

"Are there only these five? But now it seems that only Li Xuanfeng's family remains......" Wang Yuan said.

"Well, I inquired, Zheng Yang left this village when he was eight years old and never came back, so his house was gone a long time ago. And Li Tieshi has already died of illness, so the house has also been renovated, and Zhao Lame's house was also destroyed by fire the year before last, and now only the old village chief Li Xuanfeng remains. Zhao Bin said.

"This is really a headache...... Wang Yuan said as he rubbed his face.

"It looks like there must have been some story in it twenty years ago." Zhao Bin said.

Wang Yuan then told Qi Zhuang and Zhao Bin all the things that had happened from Liu Xingye to him at the beginning, and all the things that happened yesterday, neither of them had imagined that there were so many confusing stories about this Yan Shengshan twenty years ago.

"Oh my God, are you really going to take Professor Zhou to that square lake next Saturday?" Qi Zhuang asked.

"The plan is." Wang Yuan said. "By the way, Zhao Bin, do you think it is very likely that that the Underworld Pool Kingdom exists?"

"Actually, when we were swimming in the square lake, I noticed those symbols, but if you think about the perennial erosion of the current, those symbols are still so clear, and history is definitely not a historical relic." Zhao Bin said.

"No, Professor Zhou also said about this problem, but if you think about it this way, those symbols may have been washed out after the opening of the river in the village." Wang Yuan said. "At first, it was probably a swamp or something like mud, so it was well preserved, but when the water from the river came in, it washed out the contents of the river......

After listening to Wang Yuan's words, Zhao Bin seemed to suddenly realize, and said: "Indeed, I didn't notice this before, it seems that Yan Shengshan is going to make a big discovery!" ”

"Shall we go with us next Saturday?" Qi Zhuang said.

"No, you can't go next Saturday, and you have to do me a favor." Wang Yuan said.

"Huh? Why can't you go. Qi Zhuang complained.

"You have to help me watch out for the fire in Yan Shengshan." Wang Yuan said.

"What? How do we watch out. ”

"You have to watch the mountain in Uncle Liu's house, and block all people from outside us from entering the mountain." Wang Yuan said.

"Will this work?" Zhao Bin said.

"Listen, the fire in Yan Shengshan since ancient times must be man-made, it is nothing more than to get the secret of Yan Shengshan, Uncle Liu has never had a fire since he saw the mountain, this is evidence, if we enter the mountain, it is very likely that it will attract the attention of some people, so you can't let anyone cross the front mountain, and you will still have the opportunity to go to the square lake in the future." Wang Yuan said.

"Okay, we'll listen to you." Qi Zhuang said.
