The wooden box was empty at this time, and there was nothing. Looking at the wooden box with nothing inside, Cheng Yang also felt surprised, and then Yun Haifeng, who was standing behind him, said: "This wooden box is not for people, it can be analyzed from the symbols on the wooden box." ”

"Not for pretending?" Cheng Yang looked back and said questioningly.

The surrounding historical research scholars also stopped their busy footsteps and looked at Yun Haifeng, Yun Haifeng looked at the wooden box and said: "This kind of wooden box is indeed not used for people, you see that the wooden box lid of the wooden box is engraved with a 7, it is obvious that this is the town palace box used for the town house in the underground palace." ”

"We've seen a lot of Zhengong boxes, but we've never seen such wooden boxes, is it wrong?" At this moment, an old man with gray hair came out of the crowd.

Yun Haifeng shook his head and said: "The general palace box is indeed not like this, but this wooden box is not just for the town to live in this house, Mayor Town, do you hold activities here near here every fifteenth day of the full moon?" ”

When the mayor heard this, he hurriedly said: "That's right, our town will hold an event near this place on the fifteenth day of the full moon every month, and there will be no traces on the ground after the event is held. ”

"You go to the bottom of the wooden box and feel it to see if it's the residue of the burning dust on the ground." Yun Haifeng pretended to be mysterious and said.

The old man on the side made a gesture to the person behind him, and then one of them took a sample from the bottom of the wooden box and took it to a nearby testing machine, and said after a while: "Liu Lao is right, it is indeed dust that has been burned by dust."

Yun Haifeng looked at each other with a smile, but Liu Lao frowned at this time, he had been working in the historical research industry for almost 40 years, but he had never seen such a wooden box.

"How do you see that, friend?" Liu Lao asked.

"It's just common sense, but after so many years, these common sense has basically disappeared, in fact, these wooden boxes are custom-made, and they are used for suppression, and these materials should be able to find out these records if you carefully check the information." Yun Haifeng explained.

Liu Lao nodded and wrote it down, and then asked, "What you just said about 7, do you mean that there are other identical wooden boxes down here?" ”

"That's natural, I think there's a main wooden box underneath here, and there's something to make a noise in it."

Cheng Yang didn't look at the wooden box, but walked out of the crowd, and then came to the machine that was hanging things. At this time, there was no one here, so Cheng Yang easily started the machine.

The loud noise of the machine attracted everyone's attention, and the staff who were originally operating the machine ran out of the crowd and shouted, "Don't touch that machine." ”

Cheng Yang did not stop, but continued to use the touch version to control the machine, and then he stopped. Cheng Yang saw that the detector at the bottom of the hook fed back information, and 6 dense red dots appeared on the display.

"Found it." Cheng Yang said.

The people around were quiet, waiting for what Cheng Yang would do next, when Yun Haifeng and Liu Lao also came over from behind.

Yun Haifeng came to Cheng Yang's side, and then adjusted his position, then the rope tightened, and then the red dot began to slowly move upward on the vertical screen.

The wait was always long, and a wooden box was slowly pulled up from the ground, and a few people came running from the crowd to help.

Soon the wooden box was placed in the tent, and the original unboxer came to the wooden box again, but this time he was careful, the speed of unpacking had been reduced to the minimum, and as the lid of the wooden box slowly rose, he heard someone shouting: "Come out, the wooden box is open!" ”

The originally quiet scene immediately rioted after hearing this, and the historical researchers who were originally resting in the back row also rushed to the side of the wooden box.

"This is, lyre! Oh, my God! Then a voice came from the crowd.

"Lyre, it seems that there are still some things in this wooden box that are worth studying," Yun Haifeng said as he looked at the place where the wooden box was.

Cheng Yang and Yun Haifeng were not in the crowd, Cheng Yang looked at the crowd and said: "There should be something worth looking for down here, find a way to find a reason, let's go down and take a look!" ”

Yun Haifeng thought for a while and said: "We don't need to find a reason, they will invite us to go down, that Liu Lao is a member of the history team just now, but he was originally here to guide." ”

Before Yun Haifeng's words fell, Cheng Yang saw Liu Lao walking out of the crowd, and then said with a smile: "These two little brothers, can you find a place to talk alone?" ”

Lu Qiu was already dealing with Xue Longrui at this time, Cheng Yang made a gesture to Lu Qiu and then went out with Liu Lao.

The three of them came to a simple house, Cheng Yanghuan looked around, this should be the office of these historical research scholars or the usual gathering place, although it is a simple house, but at this time it looks decent.

"Two little brothers, please sit down, this environment is not very good, please forgive me." Liu Lao said with a smile.

Looking at the other party's smile, Cheng Yang suddenly understood why Yun Haifeng said just now that someone would invite him down, Yun Haifeng said with a smile: "Old Liu, you don't have to be polite, if there is anything you can do, you can do it directly, I have done my best to do it." ”

Liu Lao looked at Yun Haifeng and then sighed and said: "In the past few years, my body has slowly developed problems, and it will always be affected by these things after all, I am already old, so I want to ask the two of you to see if you can take the lead this time, so that I can rest assured a lot." ”

Yun Haifeng frowned after hearing Liu Lao's words, pondered for a while and said: "Liu Lao's matter is not such an easy thing to do, we are not professional people, you must know a lot more about professional things than us, and there are so many research scholars outside, they will definitely be better than the two of us!" ”

Liu Lao waved his hand and sighed and said, "They are all half-, and none of them can compare with the two of you, so I want to ask you two to agree to my request as an old man." ”

At this time, Yun Haifeng was thinking without listening, after all, it is a trivial matter to go down, but once something goes wrong, it will be a big matter, and I don't know what unknown dangers exist below.

Liu Lao looked at Yun Haifeng for a long time and didn't speak, and then said: "I can give you the certificate of the historical research institute, and I can give you the maximum amount of protection, and it will not restrict your freedom, what do you think?" ”

Hearing Liu Lao's words, Yun Haifeng's eyes lit up, and then said: "Let's say it first, I can only promise to help you this time, if there is such a thing next time, we will not act easily because of the proof you gave." ”

"No problem, no problem, I swear with my character that I will never force you two back." Liu Lao was very happy at this time, his level had no way to explore the world below, and if there were no two people, even the history team would not dare to go down easily.
