Zhang Zhongqing smiled, "It's really here, how many people do you say you can seduce in?" ”

Leng Feng shook his head, "I don't know, there are thirty or forty foreign spies found by my subordinates, but now only three have appeared." Let's hope these three people won't rush in. ”

A ground-level thunderbolt, if it kills three people, it's a blood loss!

Hawkers, anyway, taking a ground-level thunder and letting it sound is a loser's behavior. I just don't know if Zhang Zhongqing will be more comfortable if only three people die?

All three squinted at the movements of the three spies, and when they touched the vicinity of the cave, they did not choose to enter, but made a mark and left the place.

Seeing them leaving, Zhang Zhongqing clapped his hands excitedly, "Haha, sure enough, they still have to ask someone to go in together!" I hope more people will come in a while! ”

Leng Feng put down the binoculars and said, "If there are many people, they will definitely find that box." Now are we trying to find a way to protect our safety? ”

The distance between the mountain and the cave is only a few hundred meters, and the sand and gravel brought up by the earth-level thunder explosion are estimated to reach this side.

Zhang Zhongqing also said, "We really have to prepare for protection, our distance is also within the affected range, it's not safe." ”

Regarding gunpowder weapons, Zhang Zhongqing is an expert, and it is right to listen to him.

Leng Feng said to Li Erniu and others, "Move!" Let's move the tent back or behind the tree, and set up a wooden shelf on the top of the tent. ”

Being the boss is good for this, and if you want to do anything, as long as you are told to do it, someone will help you do it.

Soon after, the tent was moved behind three trees and wooden shelves were erected to block the top of the tent.

Everything is ready, just wait for the fish to take the bait.

However, on this day, no one came

At sunset, Zhang Zhongqing put down the binoculars and said helplessly, "This group of turtle grandchildren won't dare to come!" If they don't come, aren't we arranging it for nothing? ”

Leng Feng patted him on the shoulder, but he screamed in pain.

"I'm sorry, I forgot you were hurt."

Leng Feng withdrew his hand awkwardly and continued, "If you don't come today, it can only mean that more people will come tomorrow, what are you worried about." ”

Looking at the sunset in the west, Zhang Zhongqing asked, "They don't plan to touch it at night by taking advantage of the darkness!" ”

Feng Ang shook his head, "Even I know that gunpowder can't be close to fire, so when they come at night, do they just touch it by hand?" ”

Zhang Zhongqing breathed a sigh of relief, he knew all this, but when he thought that his trap was about to be activated, he was in a hurry.

Drilling back into the quilt, Zhang Zhongqing's voice came out through the quilt, "I won't eat dinner, call me up early tomorrow morning." ”

It's not okay to skip dinner, this sick person still has to drink medicine!

So Leng Feng simply got out of the tent and grabbed a handful of snow, threatening Zhang Zhongqing to get out again.

Nothing was said all night

Early the next morning, after Leng Feng and the others had breakfast, they continued to observe the intersection with a telescope.

If they live in Chang'an City, then they can only wait for the city gate to open before entering, and if they live outside Chang'an City, then they can appear as soon as dawn.

Based on the time they came, it is possible to roughly deduce where they lived.

At about midnight, a convoy appeared at the mountain pass, and as far as the eye could see, there were thirty or forty people.

This number of people

Zhang Zhongqing clapped his hands excitedly, "This is enough, how can three or five people do it, how can it take thirty or fifty people to do it!" ”

Feng Ang was surprised: "Why are so many people here?" And horse-drawn carriages. They thought they could move something? ”

Leng Feng was also a little shocked, this guy's, the carriage has come up, these people are too taken for granted!

At first, the Thunderbolt Division was near the Literary Academy, but later moved the place, and when they moved, they were eager to sweep the land and take it away, for fear of leaving any clues.

What if they find the ruins of the Thunderbolts? They couldn't see anything but the building.

The group advanced all the way to the vicinity of the cave, and first sent the three accomplices dressed as woodcutters into the cave to explore the way, and only after making sure that there was no danger before moving on.

Seeing that there were still a few people scattered to check the surroundings, Zhang Zhongqing said anxiously, "Why don't you all go in?" If you're outside, you probably won't be able to blow up! ”

Leng Feng said helplessly: "You really want to be able to take them all together!" This is their normal action, doing sneaky things, how can they let the family have a chance to be sentry! ”

Feng Ang never put down the binoculars, and after seeing a few more people entering, he said, "Now there are more than half of the people who have entered the cave, is your trap so deep?" You're not afraid that they'll give up here if they don't find anything? ”

Leng Feng smiled slightly, "Naturally I'm not afraid, I set some temptations for them, and they will only continue to look inside." ”

At that time, the psychologist Skinner designed an experimental device: he put the hungry mice into the box, and there was a lever on the wall of the box that could be pressed, as long as the mouse pressed the lever, there was a certain probability that the food would fall out, and this device was later the famous Skinner box.

I won't repeat the changes since then, but the truth of the Skinner box is to take advantage of the luck psychology that does not only exist in humans.

In the cave, at first, it was just some broken wood, nothing out of the ordinary.

But in the future, there will be a shattered thunderbolt arrow, a thunderbolt shell without gunpowder, and there will always be something that will make those who find it happy.

That way, they keep going deeper until they find that box.

Even if they opened the box and fled immediately after activating the ground-level thunder, it would definitely be too late.

Of course, it's impossible for them to pee and nourish it. Not to mention that the waterproof gunpowder fuze that Zhang Zhongqing made can avoid being extinguished to a certain extent, even the fuse of the ground-level thunder has now become an embedded type.

As for whether the ground-level thunder can be activated

Leng Feng felt that if there was a problem with the organ, it was estimated that the public would have to roll out of the academy if he broke through.

The three of them rubbed their hands together, eager to hear the roar of ground-level thunder.

Now their mentality is the same as that of children who go to the river with two kicks in winter to blow up Bingbing.

After a long time

Feng Ang suddenly glanced at Leng Feng strangely, "How does the old man feel, that mountain is moving?" ”

Leng Feng nodded, and then stuffed cotton on one ear with Zhang Zhongqing, covered the other ear with his free hand, and opened his mouth.

Feng Ang saw that they all did this, and hurriedly followed their example.

Through the telescope, you can see that the side of the dirt mountain, which was originally "quiet", is trembling like a shivering person.

Then, there is the dust that spews out.

Finally, the mountain above the cave collapsed!

All this is just three seconds.

It wasn't until the moment the mountain collapsed that the roar came!
