The big golden tooth pondered for a long time and said, "Second master, Miss Yang, forgive me for not listening to a word, I think the next clue is obvious." ”

All three of us were shocked to hear this. I only heard the big golden tooth continue: "Hu Ye's previous analysis was right, that is, to focus on large, easy-to-preserve buildings, so as to ensure the long-term preservation of clues. And looking at the southeast 54 degrees, there are not many buildings before the Ming Dynasty on this route, except for the Great Wall, Sanqing Temple, and Mengjiang Temple. The third line of the poem is '100,000 unjust souls pave the long road', which is obviously talking about the Great Wall. In order to defend against foreign enemies, it is said that 100,000 people were mobilized to build the Great Wall, and the bones of the tired people were filled in the Great Wall. Although the Great Wall of Shanhaiguan is the Great Wall of the Ming Dynasty, the meaning should be the same. ”

The words of the big golden tooth made the three of us suddenly enlightened, and the more we thought about it, the more we felt that the next clue was in the Great Wall. The fat man grabbed the hand of the big gold tooth and said: "Lao Jin, he really deserves to be the genius of Panjiayuan, who knows astronomy and geography." Every time I see the chic of your expedition, I can't help but sigh at my simplicity and ignorance. ”

I quickly stopped the conversation: "Forget it, Chubby, it's true to say that you are ignorant, but don't spoil the word 'simple'." You look like you're full of fat, you can't be linked to simplicity. But Lao Jin, your analysis is really meticulous, and I am convinced. ”

The big golden tooth said with a smile: "Where and where, you three are fans of the authorities, and I am nothing more than random speculation, just a false mouth." ”

Shirley Yang lowered his head and compared the drawings on the map and said, "Brother Jin, according to this analysis, the location of the next clue should be the intersection of the Great Wall and the 45th parallel line in the southeast. That's it. As he spoke, his fingers slid down the 45-degree red line and stopped in one place. Here, the old dragon head. ”

The three of us looked down and found that this old dragon's head was on the seaside, which was the entrance to the sea of the Great Wall. Shirley Yang said: "Oops, the clue may be in the sea, and it is really inconvenient for us to have no scuba!" ”

I muttered, "At present, it may be very difficult to find a few pairs of scuba in the county seat, and I am afraid that it will be delayed for many days to go back to Beijing to find them again." Let's go to the old faucet first, maybe the clue is not in the water. ”

The fat man said: "Now that the guy has arrived and the clue location has been found, then what are we waiting for, let's leave tonight." Fat man, I want to see what other tricks this Chen family can make. ”

I said to the big golden tooth: "Lao Jin, thank you for coming here to send off a guy, you can go back this afternoon if there is nothing to do, and you can't do without the business of Panjiayuan." ”

The big golden tooth said: "Master Hu, otherwise I will wait for you here, if there is anything you need, you can still have a care." Compared with the friendship between us, Panjiayuan's business is a trivial matter. ”

I waved my hand and said, "It's okay, you better go back first." To be honest, the process of finding the Chen family's tomb was more difficult than we expected, and we don't know what will happen next, and you are also scared to wait here. It's better to go back to Panjiayuan first to settle the rear for us, and we will inform you as soon as there is news. ”

When the big gold tooth saw that I insisted, he didn't say anything more. The four of us had lunch, sent the big gold tooth away, and then went back to the hotel to rest and prepare, waiting for the evening to go to the old dragon's head. It was finally dark that we found the carriage we had agreed with at noon, and ran to the old dragon's head.

Before it was dark, there were many fewer pedestrians on the road. The more we walked to the beach, the more there was no one, and by the time we reached the old dragon's head, it was already dark, and there was no pedestrian on the road. The uncle who drove the car turned around and asked, "Little dolls, what are you doing in this dark day?" The scenery is good, but the sky is dark and you can't see anything, so be careful to fall into the sea. ”

Shirley Yang replied: "Uncle, we are from the Academy of Natural Sciences, and we mainly want to record the relationship between the changes in the lunar cycle and the tides, so we must go to the beach at night." Thank you for your concern. ”
