After hanging up the phone, Professor Chen thought for a few seconds and then continued to ask Sun Ju: "Do you think that F is the initial letter of a person's name?" ”

"This is uncertain for the time being, but it is impossible to rule it out, judging by past experience, it will not be so simple."

"There's no movement from that f right now? Haven't shown your head yet, have you? ”

"Yes, he hasn't moved, so we still need to be patient; Section Chief Xing interrogated several foreign prisoners in the city bureau, and now the structure of the gang has been basically determined, but those foreigners are all hired and belong to the outlaw type; I got in touch with the International Criminal Police Organization (ICPO), and I sent some information about the Centipede Cult, including some information about several fugitives, and is now doing the communication of the case and the docking of evidence. ”

"Is there any news of the fugitives now?"

"No, they're gone, there's no trace."

"So, how many suspicious people are there around us now?"

"The people on the list, and the others, at this point, have no direct evidence that they have a problem, and anyone is suspicious based on their feelings alone."

"Personally, I don't think it's possible that everyone will be associated with the tomb robbers."

"Yes, many people should just be for their own selfish desires, and they will not be involved in the tomb robbery group, if the tomb robbery group uses people everywhere, it will be full of loopholes a long time ago."

"Well, the rest of the matter, you have to work hard."

With that, Professor Chen returned to his room and slowly finished his presentation.

When there is something to do, time always flies quickly, and before you know it, it is getting dark. Professor Chen saw that Zhang Gong and the others had not come back yet, and looked at his watch, it was already 18:37. He suddenly felt a little ominous in his heart, so he put on his coat and hurried to the cave.

More than half an hour later, he arrived. Everything here looks normal, and the few people on duty above are laughing, and when they see Professor Chen coming, they all politely say hello.

After seeing them, Professor Chen's heart became a little more steady, and he asked, "What about them?" Why didn't you come up so late? ”

"Situ Fang, they have finished probing the bottom, and now they have also entered the hole in the middle."

"How long has it been since you last saw them?"

"It's been almost two hours."

"Okay, you're still on duty here, I'll go down and have a look first."

A uniformed SWAT officer said, "No, Professor, it's not safe for you to go down alone, or I'll accompany you." ”

Professor Chen looked at the team member, nodded and said, "It's okay, then the rest of you will continue to stay here, in order to prevent another sneak attack, you stand on that side, and ensure that your eyes can see the direction of the passage at any time." ”

After that, Professor Chen put on his climbing gear and slowly slid down the rope.

After entering the hole, the two of them just kept going inside. But until I walked to the end of the passage, that is, the cave with murals, I didn't see Zhang Gong and them, and I didn't see any traces on the way.

Professor Chen chuckled in his heart, thinking to himself: they must have entered another hidden space. So, he decided to go back, and kept pressing the buttons on the walkie-talkie along the way. But it was all in vain, and there was no reply on the intercom.

Soon, they arrived at the entrance of the cave, and Professor Chen said to the special police officer who accompanied him: "You go up, explain what you have found here to Team Fan, and ask him to come over quickly with equipment and people." ”

Seeing that the SWAT team member had gone up, Professor Chan walked back along the passage, carefully looking for clues, but still did not find it. Nearly half an hour passed below, and Team Fan came down with a dozen or so people.

Team Fan saw Professor Chen's hand and asked anxiously, "Professor, are you sure they disappeared in this hole?" ”

"Yes, when I came, I asked a few of the people above, and they all said that they saw them go in with their own eyes."

"Then let's move forward while probing, I think this will definitely be found, don't worry."

"You guys be careful, it's better to keep a distance, I think there's something wrong with this passage, they must be following the new path, going somewhere."

"Okay, let's learn from the last time, let's spread out and search forward."

Professor Chen was a little tired, so he found a place to dry, sat down to rest, and the previous work was carried out by Team Fan. After a few minutes of slowing down, Professor Chen stood up and walked in quickly, trying to catch up with Fan and them quickly. But he walked for about 10 minutes, and he was dumbfounded: the front was almost at the end again, and he didn't find Team Fan and them along the way. He suddenly felt a little frightened, and plucked up the courage to continue walking a few steps forward, only to confirm behind the stone statue that the Fan team had also disappeared.

Professor Chen secretly felt that something was wrong, and after sitting down, he pondered for a while, and walked back to the entrance of the cave. Then, from the entrance of the cave, according to the time and speed, after estimating the approximate location range of the Fan team's disappearance, he made a few marks there, and then carefully searched for it in the direction of the cave entrance. But all he did was in vain, and soon the cave was in front of him.

Professor Chen sat down again in frustration, took out his walkie-talkie and said weakly: "You go find some more people, and at the same time find a ground penetrating imager to come down and ask for three-dimensional imaging." ”

The walkie-talkie quickly responded, and a more stable voice said, "Didn't Team Fan go down just now?" ”

"It's also lost, you find a few more people to come down, and at the same time, notify them again, bring more flashlights down."

While waiting, Professor Chen couldn't figure out how Zhang Gong and Team Fan disappeared, and now there was no one around him to discuss, he felt a little lonely, and that loneliness made him a little flustered.

Soon, under the leadership of the special police officer just now, a few more people came. Seeing so many headlamps and flashlights, Professor Chen felt confident again, and he cheered up and walked in front of the team with a 3D imager. After 7 minutes of scanning, he suddenly felt that something was wrong, but he couldn't say it, and after a slight pause under his feet, he continued to move forward.

Finally, after walking for 10 minutes, he looked at his watch, resolutely stopped, turned to the person behind him and said, "Don't go yet, this is not the original passage!" ”

The SWAT asked, "We haven't encountered a fork in the road, why isn't it the same way we have been going?" ”

"We fell into a passage that looked like that, but I'm sure it's not the original one."

"I look the same, how are you sure?"

"I just drew obvious marks on the ground and the walls of the cave on both sides, but until now, I haven't found it, and I should have seen it a long time ago."

"Could it be that it hasn't arrived yet?"

"Impossible! We've definitely fallen into a new space! ”
