"What?" I said.

"That's right, Professor Lu Youwei was originally scheduled to continue the excavation experiment next to the hole today, but this morning the professor did not show up. The only clue found was that at about 1 a.m. yesterday, Professor Lu Youwei said that an important document had been left in the laboratory, and he did not come out after asking the driver to take him to the laboratory. The driver thought that everyone had already arrived early and didn't think much about going back, and when the others arrived in the morning, Professor Lu Youwei was gone. The young man said this, snorting and spitting.

"Gone?" I said.

"We are tentatively designated as missing, and kidnapping and conspiracy cannot be ruled out." The young man nodded.

I suddenly remembered the email chat my dad sent to me yesterday, and I understood that my dad was in the hole. But he himself clearly said that he was not in a hurry to experiment, why did he suddenly advance it?

The young man looked at me as puzzled, and said again, "We will find Professor Lu Youwei here as soon as possible, but we need to trouble you before that." ”

"Trouble me? Where is Staff Officer Liu? I said.

"The staff officer you mentioned has been transferred due to negligence in handling the matter, and I am now in charge of this matter. My surname is Han Dong, and you don't need to be a spokesperson for the media anymore, Mr. Lu Qiao. Han Dong said.

"And what do you want me to do?" I said.

"Mr. Luqiao seems to be a sensible person, so I won't beat around the bush. We are very sorry for your father's disappearance, but the project must be supervised and executed. We thought about finding someone else to replace us, but the crowd is bound to be mixed. We don't want to make it too public, obviously you can't just leave it alone. So we want you to start taking the position of Professor Lu Youwei now and help us continue the experiment. Han Dong said.

"I don't know about my dad, how can I help you?" I said.

"You don't need to know anything, the information and itinerary are all here. You just need to watch the execution and alert you when something goes wrong on the spot. And we also believe that Professor Lu Youwei once told you what we are going to do next, right? Han Dong said, opening the box he was holding in his hand.

Inside the box are several document contracts that need to be signed, as well as a thick execution book.

I thought about it and said, "Do you want to dig a 1,500-meter hole horizontally not far from the hole, and then measure it in the direction of the hole folding and extending?"

Han Dong took out the pen in his pocket and said, "I know that your father has almost told you about the matter, so it saves us from having to tell you what we are going to do again." Here are a few contracts that you need to sign, so please ask the North Great Wall to supervise the experiment on site in the afternoon. ”

Han Dong handed me the pen and pointed to the place where I needed to sign the contract.

Han Dong said with a smile: "After signing, the next thing you do will be a top-secret file, and you must not disclose it to anyone in any form." Otherwise, it will be treated as a traitorous crime, do you understand? ”

"What if I don't sign it?" I said.

"Because you know too much here, we'll protect you properly. We will let you go until the incident is fully investigated, otherwise please be patient. Han Dong said.

I picked up the pen and signed my name without thinking too much, and when I was done, I said, "My dad won't have an accident, right?" ”

"I just forgot to mention that because of your father's experience, we have tentatively defined it as a conspiracy to escape and treason, so from today onwards, I will be in charge of staying with you twenty-four hours a day to ensure that you do not disappear again, now remove your makeup and follow me." Han Dong said.
