By angry brain shell pain, Professor Du pointed to the remaining two students: "you two go down, I'll give you double credits, papers I don't make you difficult, speed point."

When they heard this, their eyes were full of light. My darling, this is the rhythm that graduate students can graduate from. Great, ha ha.

"Professor Du, we must keep a good attitude to do research."

After expressing their attitude, they immediately ran back to get the equipment and instruments, and then quickly went down to check the geology of the collapse.

"Lin fan, what's going on?"

After seeing Professor Du's apprenticeship play, Guo Yuyan asked in a voice that only two people could hear: "is it dangerous to let them go down like this?"

"There is a price to be paid for stupidity, and even if there is danger, it is their own fault."

Seeing Professor Du with a nervous face, Lin Fan joked, "let's have a look first. Even if the soil collapses, they will not die."

Just now, although he didn't pay attention to it, it doesn't mean he really ignored it. The mud and stone under the construction site is very hard, but it can be ignored.

What's more, there's no rule in this kind of collapse, which means that the thing is doing what it wants. You can come whenever you want to, which makes it more difficult to find.

Now the students of all professors go down to test, and the sound wave emitted by the instrument may not be effective. In fact, it was also true. Just as the two men were testing, a faint vibration began to emerge from below the ground.

"Professor Du, we checked it. It's all right."

Looking at the data displayed in the device, the student below waved and exclaimed, "everything is normal. This collapse should be an accident, an accident."

"Mr. Lin, do you hear me? There's no problem with geology. It's an accident. "

After hearing that there was no problem, Professor Du's heart fell to the ground: "we are professional, we have checked, and if there is no problem, we really have no problem."

"Garbage, the problem begins."

Feeling the vibration of the ground, Lin Fan snorted coldly: "shut up, don't bother me."

"Mr. Lin, what do you mean, even if you don't like to listen to me."

Infuriated by Lin Fan's attitude, Professor Du scolded: "I tell you, today's matter..."

Boom ~

another blast broke out, interrupting what he wanted to say again. But this time the movement is obviously bigger than the one just now, so I close my mouth and look at it anxiously.

Damn it, it's really a sin to come to any pot without mentioning it.

Just ready to reprimand Lin fan to get back to the court, however, he was beaten in the face after half of his words. He really wanted to slap himself in the face and become a crow's mouth.

Where is this time? Which direction will collapse?

Although the vibration of the ground was observed, it could not be locked, and there was a problem. Under the half excavated foundation, only the surrounding soil can collapse, right?

However, a flash came out of his mind, and Lin Fan found that he had neglected one thing. The two students tossed out the equipment and equipment, and the sound wave emitted attracted the object.

It controls the soil, which means it may be deeper down. Thinking of this, Lin Fan secretly yelled at the following two students: "you hurry up, danger, there is danger below."

Lin Fan's voice is so loud that the whole construction site can be heard clearly. The following two graduate students listen very clearly, but their faces are curious and puzzled.

They all checked the geology. The collapse was just an accident. What's the danger? Look around. Everything is safe.

"Damn it, it's really at the bottom."
