Wherever the searchlight went, the visibility had indeed improved a lot. But within Pang Qingshan's field of vision, apart from a mess, he didn't find much.

"Isn't this the same as before?" Pang Qingshan complained.

Unexpectedly, Shi Shishi did not speak, but walked straight to a dilapidated experimental cabinet.

"Qingshan, come and see, there is something wrong with this cabinet."

"There is a problem. What can be wrong with this broken cabinet?"

"This cabinet is much newer than the other cabinets, and judging from the signs of damage on it, it doesn't look like there are very old scars. It seems like someone deliberately made this cabinet older, and the rust spots were also treated."

"Really?" Pang Qingshan took a closer look and found that, as Shi Shishi said, the color of these rust spots was much lighter than that of the cabinet next to it.

"How long has this experimental building been abandoned?" Shi Shishi asked.

"Almost ten years! It was abandoned before Principal Cheng came."

"It's been more than ten years, but this cabinet has been moved for about two or three years at most. It seems like the agency is here."

"There must be something hidden behind this, let me come and have a look!" Pang Qingshan hurriedly groped around on the wall next to it.

"There's no need to look for it. There should be no mechanism in this cabinet."

"No mechanism?"

"If there is a trap, you and Shuangshuang should have discovered it last time."

"There is no mechanism, so how can you move this cabinet? It's hard to rely on manpower to move such a heavy thing!"

Unexpectedly, before Pang Qingshan finished speaking, Shi Shisi had already moved the cabinet away. And behind the cabinet, a door was revealed.

"Brother Fourteen is still awesome."

"This place is already quite safe, and there is no need to cover it up. Having an agency will only arouse other people's suspicions."

"But it's impossible for everyone to be born with supernatural powers like you, Brother Fourteen!"

"Although this cabinet is heavy, one or two people can easily move it with the help of tools."

"I see, then without further delay, let's go in and take a look first!"

After Pang Qingshan finished speaking, he quickly ran to the secret door. He saw that there seemed to be a crack in the middle of the secret door. Other than that, he looked for a long time and found no mechanism.

"It seems that this also relies on human power!" Pang Qingshan said to himself.

"Qingshan, this door..."

When Shi Shishi was about to speak, Pang Qingshan immediately interrupted. "Brother Shi Shi, leave this door to me. I am also very strong!"

After Pang Qingshan finished speaking, he ran over and tried his best to move the secret door open. However, despite all his efforts, the door did not move at all.

"This door can't be opened!" Pang Qingshan was also discouraged.

Unexpectedly, at this time, the door automatically separated from both sides. A ray of light shot out, causing Pang Qingshan to raise his head. It turned out that behind the secret door, there was an elevator.

Just when Pang Qingshan was wondering, Shi Shishi's words came from behind.

"Actually, I wanted to tell you before!" Shi Shisi pointed to the button on the side and said, "The elevator switch is here."

"Uh!" Pang Qingshan almost fell over.

"Okay, let's go in quickly and see where this elevator leads!" Shi Shishi urged.

The two walked into the elevator, and the screen inside showed that the elevator actually led to the underground.

"Is there anything hidden under the experimental building?" Shi Shishi frowned, "It does seem too abnormal."

The elevator door slowly closed, and with the sound of mechanical creaking, the elevator descended to the third underground floor.

At the same time, in the French restaurant, students were enthusiastically studying "The Hundred Years' War between England and France".

“‘hundred                                                                                                                                                                                                                                                                                                   ​

Not more than 116 years ago, the dynasty that ruled England at that time was the Plantagenet dynasty. The participating parties, the French camp, included: the Kingdom of France, the Kingdom of Scotland, the Kingdom of Castile, etc.; and the other side included: England, Burgundy

The kingdom waits..."

"There are so many kingdoms participating in the war! Teacher Sheldon, please continue, continue!" Lu Qi said excitedly while chewing on the leg of lamb.

"It was originally just a question that Yoona asked Teacher Sheldon, but why did it turn into a history lesson!" Morishan couldn't help complaining.

"It's not your brother who is a military fan who is adding fuel to the flames. When he heard about the war, he was as excited as a teenager!" Pan Yi said.

"Sorry, we all seem to be teenagers."

Pan Yi: "..."

Sheldon is worthy of being an educator in European history. He explained the Hundred Years War in a simple and easy-to-understand manner from the aspects of politics, economy, social relations, international relations, etc. Even Lucci, who has average cognitive ability, listened.

With relish.

"Okay, the whole war process is almost like this. I think there should be no problems!" Sheldon asked.

"Thank you so much, Teacher Sheldon." Situ Yuner said respectfully, "The 'Hundred Years War' was explained very clearly. I don't have any questions anymore."

"That's good, I think I can say goodbye!"

"Wait a minute, Teacher Sheldon. There is no problem originally, but you have involved the Kingdom of Burgundy and the Kingdom of Castile. I still know very little about the history of these two kingdoms. Could you please help us?

Please explain it!" Situ Yuner blinked her innocent big eyes, showing a strong desire for knowledge.

"This..." Sheldon naturally didn't want to stay here anymore, but the countless looks from around him forced him to give in again.

"Okay then!" He continued to explain helplessly.

Er Shuang on the side looked at the mobile phone from time to time, thinking: "Shitou, you have to be faster! We can't delay this foreigner for too long."

At this time, Shi Shishi and Pang Qingshan had already walked out of the elevator, and what appeared in front of them turned out to be closed laboratories.

Rows of night lights were arranged under the walls on both sides of the corridor, flashing weak lights. A few flickered on and off, making people a little creepy.

Shi Shishi and Pang Qingshan walked cautiously, fearing that the information here would be disturbed. You must be aware of the alarm device, which is a common device installed in all such secret bases.

The two opened several laboratory doors, but there was nothing strange inside. There were only some ordinary experimental instruments placed there.

"It's a pity that we don't have Yoona's remote support now, otherwise we could still find something valuable." Shi Shisi said to himself.

"Brother Fourteen, look at this room." Pang Qingshan pointed to a door in the corner not far away and said.

This door is completely different from other laboratory doors. In addition to being made of metal, there is a square metal device placed next to the door.

"It seems to be a combination lock!" Pang Qingshan said looking at the metal square box.

"We can't crack the fingerprint identification system now." Shi Shisi looked at it and said, "But with so many security facilities built into this door, there must be something extremely important inside."

"Then what should we do? If we force it open, we might alert the snake!"

"Then we can only go to other places to look. How can we come back empty-handed after entering Baoshan." Shi Shisi said, and began to look left and right again. The inconspicuous mechanical door at the entrance caught his attention.

"This door also seems to have a code lock, but it doesn't use fingerprints." Shi Shisi walked to the door and said while looking at the code lock.

"It's really hard to spot if it's placed in this location. It seems like there must be some ulterior secret hidden inside."

"How to open it like that is a question." Shi Shisi looked at the numbers in the nine-square grid and fell into deep thought.

"I know this section well." Pang Qingshan confidently took out a can of spray and sprayed it. After a while, several fingerprints appeared on the nine-square grid.

"Fingerprint revealing spray, you are already prepared!"

"That's right! Aren't all scenes in movies like this?" Pang Qingshan said proudly, "Then I just need to arrange and combine these numbers with fingerprints."

"There are five numbers in total, but this combination lock seems to have six digits! One of them is repeated, if that's the case." Shi Shishi's mind turned quickly, "If you use the permutation and combination formula to calculate it, it should be: p

(5,1)×p(5,4)=600. You should be able to open it after losing 600 times.”

"Brother Fourteen, you are really made to be a teacher, even though I have no idea what you are talking about." Pang Qingshan said embarrassedly.

"I remember that this permutation and combination was not a high school question! How did you take the undergraduate exam?"

"After all these years, I have already returned it to the teacher! And I am not a science major in university, okay?"

"Forget it, then just press the password 600 times and you should be able to open it."

"This seems a bit much. It takes too much time! What if Sheldon comes back in time?"

Although what Pang Qingshan said was true, how could Shi Shisi listen to it and think that this guy wanted to be lazy? "I didn't expect that after this guy woke up, he would be like the second senior brother." Shi Shisi thought carefully while thinking about it.

Observing the clues nearby.

"Strange, why is there a device similar to a microphone here!" Shi Shisi said, touching a protruding place. And next to the microphone, there seemed to be some small rough spots.

Shi Shisi touched it and smiled slightly. "So that's what it is."

"What's wrong, Brother Fourteen, what did you find?"

"Qingshan, come and see there is a piece of Braille here!"

"Braille?" Pang Qingshan came over and touched Shi Shishi's finger. There were indeed some raised little dots on it.

"That seems to be the case, but I don't know Braille either!"

"You can't, but I can!" Shi Shisi touched a few numbers and popped out a few numbers, "3323, 34323, 212343, 2212."

"Brother Fourteen, you can also read Braille!"
