Chen Weibin was about to bend down to pick up the handbag between the two tombstones, when suddenly, Chen Weibin found that Zhou Yuncai's tombstone base was a little different from Fan Shuzhen's tombstone base. Although the bases of the two tombstones are embedded in the connection of the two marble floors, Fan Shuzhen's tombstone base and the marble floor are firmly fixed together by cement, while Zhou Yuncai's tombstone base and the marble floor are not glued with cement.

That's weird! According to custom, when the deceased old man is buried, the tombstone will be fixed at that time, and it will not be moved in the future unless there are special circumstances. And why is one of the two tombstones in front of me fixed with cement, but the other not?

Chen Weibin immediately stood up, folded his hands and bowed to Zhou Yuncai's tombstone again, and said, "Old man, I'm sorry!" I'm going to move your tombstone, I hope you know and forgive me! ”

Chen Weibin's hands pinched both sides of the tombstone and began to lift it up vigorously. The tombstone is not heavy, about thirty pounds, Chen Weibin lifted it up about twenty centimeters, and easily lifted the tombstone out of the marble floor, and then gently leaned the tombstone next to Zhou Yuncai's grave.

Seeing this, the three of them immediately stepped forward and looked at the place where the tombstone base was placed.

Chen Weibin tried to move the two marble floors next to the base of the tombstone, both of which were loose and easy to move. Then, Chen Weibin carefully placed the two marble floors next to him, and the situation under the floors was displayed in front of the four people. I saw that there was no concrete under the two marble floors, but a thick black waterproof board was laid to prevent the rain from soaking the things underneath!

Chen Weibin immediately removed the waterproof board, and unexpectedly, under the waterproof board, there was actually an anti-theft door!

"Ahh Automoatic door! It's so cleverly arranged! Zhuo Min exclaimed and hurriedly started taking pictures with the camera in his phone.

Chen Weibin squatted down and tried to pull the inset handle on the security door with his hand to see if he could open the security door, but he couldn't pull it at all.

"It's locked!" Wu Zhenjie said.

Chen Weibin carefully observed the surface of the security door and found that there was a lock hole on the door, and below the lock hole, there was a numeric keypad.

Wu Zhenjie also squatted down, looked at the security door, and said: "This is an old-fashioned security door, it has been a little long, but it was definitely very advanced at that time, and it required a key and password to open." ”

"Huh? So what to do? Where do we have the keys and passwords? Zhuo Min asked anxiously.

"Or ...... Let's smash the security door open! Zhang Peng suggested.

"I guess I can't smash it." Wu Zhenjie shook his head, knocked on the security door with his fist a few times, and then said, "This security door is not an ordinary security door, it is specially customized, the steel plate is very thick, and the lock on the door is also very strong. ”

Chen Weibin looked at the keyhole and keypad, stunned without saying a word.

"Chen detachment ......" Zhuo Min looked at Chen Weibin and shouted.

At this time, Chen Weibin came back to his senses and said slowly: "I'm here...... There may be keys and passwords! ”

"Really?" The three of them looked at Chen Weibin in surprise at the same time.

Chen Weibin remembered that Zhou Xianquan had told him last time that in Zhou Yuanliang's safe, there was a key and a piece of paper with some numbers written on it. I took a photo of Yao Wenjun in Liangdong Group, and I have already asked my master to match five keys according to the film, and I have always kept it in my handbag. And the piece of paper with numbers written on it, I took a picture with my mobile phone camera at the time.

"Try it!" Chen Weibin hurriedly picked up the handbag next to him, took out five keys from the bag, and at the same time took out his mobile phone and found the photo.

Chen Weibin handed the handbag to Zhang Peng, and tried to insert one of the keys into the keyhole. The key was just right to get in, but it couldn't be twisted at all. Chen Weibin changed another key, which could also be inserted, but he still couldn't twist it. Chen Weibin continued to change, and when he changed to the fifth key, he finally twisted the door lock, only to hear a "bang", and the world lock of the anti-theft door was all opened.

"Okay!" All four screamed excitedly at the same time.

Chen Weibin tried to pull the inset handle on the security door again, but he still couldn't pull it.

"Missing the password!" Wu Zhenjie said eagerly.

Chen Weibin looked carefully at the photo on his phone, and then pressed the number on the keyboard according to the number "four-five-six-seven-four-one-two-nine" on the photo. Just a moment after Chen Weibin finished typing the numbers, there was a "beep" sound on the keyboard.

After Chen Weibin heard the sound, he immediately grabbed the embedded handle on the anti-theft door with his hand, and lifted it up forcefully, and the anti-theft door was successfully opened! Then, the security door starts to roll up automatically, and stops when it reaches perpendicular to the ground.

The four of them laughed happily, and Zhuo Min couldn't help but clap his hands!

"Good guys!" Wu Zhenjie looked at the upturned anti-theft door and said, "The steel plate of this door is 20 centimeters thick, there is no key and password, I don't think even professional demolition tools can open it, only by blasting can the door be blown open!" ”

Chen Weibin took off the key on the security door, put it in his right trouser pocket, and then looked under the door, there was a hole, and it was pitch black inside. With the light outside, Chen Weibin saw a wooden ladder at the entrance of the cave, so he immediately turned on the flashlight function on his mobile phone, shone it below, and then turned around, leaned back against the wooden ladder, and slowly moved down the wooden ladder step by step.

"You guys follow me slowly!" Chen Weibin said.

"Yes." Wu Zhenjie, Zhang Peng and Zhuo Min agreed, and at the same time, they also turned on the flashlight function on their mobile phones, shining in the hole, and moved down in turn.

After a while, Chen Weibin went down to the bottom of the wooden ladder, shone around with a flashlight, and found that it was a basement! Chen Weibin saw some emergency lights hanging on the walls of the basement, so he turned them on one by one.

Wu Zhenjie, Zhang Peng, and Zhuo Min had also gone down to the bottom, and followed Chen Weibin to turn on the emergency lights on the wall. There were more than 30 emergency lights in the basement, and when all the emergency lights were turned on, the whole picture of the basement was suddenly presented to the four people.

The basement is about four meters high, about 20 meters long and wide like a dam at ground level, and is made of concrete at the top, bottom and on all sides. In the inner area of the basement, there are large piles of black suitcases.

Chen Weibin walked to the nearest suitcase and looked at it carefully. The surface of this suitcase is black waterproof cloth, and the whole case is about 70 centimeters long, 40 centimeters wide, and 15 centimeters high. On the front side of the trunk, there was a handle. In the upper part of the suitcase, there is a pair of horizontal zippers that connect the left, front, and right sides of the suitcase.

Chen Weibin took off the suitcase with a handle in his hand, weighed the weight, and it was quite heavy, about twenty-five or six kilograms.

What's inside?
