Stay away from beasts in the world of Siheyuan

"Comrade, comrade, we are closed."

"Oh, okay, I'll leave now. I'm so sorry."

Xu Changping, who was immersed in the sea of ​​books, was awakened by the voice of the library staff. He glanced at his watch and found that it was almost eight o'clock, so he hurriedly apologized.

He stood up and twisted his sore waist, then he realized that he was the only person reading in the library. He hurriedly helped the staff put the book he had taken out back to the bookshelf.

After leaving the library, Xu Changping touched his rumbling stomach and couldn't help shaking his head and laughing. Heshen's life was so fascinating that he even forgot to eat.

However, the gains of this day were not small. Xu Changping discovered that after Qianlong awarded Shuchun Garden to Heshen, he had extensively renovated it. If Heshen wanted to leave some escape route, that would be the best time.

Looking at the tightly closed gate of the courtyard, Xu Changping felt inconvenient for the first time. He thought about it and decided to go forward and knock on the door, just in case someone came to open it.

"Bang bang bang."

Here, Yi Zhonghai took advantage of the fact that the aunt was asleep and secretly took a bag of corn flour, preparing to deliver it to the Jia family under the cover of night.

There was a knock at the door. He quickly put the things in the jar at the door, then walked to the door and asked:

"Who!"

"Uncle, it's me, Xu Changping."

When Xu Changping heard that it was Yi Zhonghai's voice, he quickly replied.

"Why are you back so late? If I hadn't come out to get something, I wouldn't have heard you knocking on the door."

When Yi Zhonghai heard Xu Changping's voice, he walked to the door, took down the bolt, and scolded Xu Changping.

"I was so engrossed in reading in the library that I forgot the time. I'll come back later next time." Xu Changping explained with a smile.

"Well, let's go home quickly." Yi Zhonghai nodded secretly after hearing Xu Changping's words. It would be fine as long as he didn't mess around outside.

"Thank you for opening the door, sir. I'll go home first." After saying that, Xu Changping ran towards the central courtyard.

After taking a quick shower, Xu Changping sat at the table holding a map of the city and thinking about the information he had read today.

Shuchun Garden is now divided into several parts. Over the years, the buildings left by Heshen have been almost destroyed, and no information about Heshen's treasure has been leaked.

Xu Changping guessed that it was either very low underground or somewhere at the bottom of the lake.

He felt that the most likely location was somewhere at the bottom of the lake, because based on his current understanding of the topography of Shuchun Garden, it should be a wetland. It would be unscientific to dig a very deep basement, as it would easily turn into a lake.

Tomorrow night he will go to the bottom of the largest lake to explore. It just so happens that the system mall has the most advanced diving equipment.

I have to say that although Xu Changping's method was not very good, it did calm down the infirmary.

He worked in the clinic all day and went straight home after get off work to wait for the arrival of night.

Taking advantage of the moonlight when everyone in the courtyard was asleep, Xu Changping climbed over the wall and left the courtyard, took out the bicycle from the space, and rushed all the way to Peking University.

Arriving at the lake of Beijing University in the dark, Xu Changping simply warmed up, took out the diving suit he bought in the system mall, changed into it, and went into the water.

Xu Changping had some experience in diving. In his previous life, when he took his students to summer camp, he learned some from his coach. Although he was not very good, it was definitely no problem for the depth of a small lake.

Given Heshen's caution, the secret room where he hid his treasure must be very well hidden. Xu Changping swam to the center of the lake before diving down.

Excuse!

What a big fish.

A huge black fish, nearly two meters long, was startled by the noise of his diving and swam up.

No wonder he didn’t see any fish in the lake for so long. It turned out that they were all eaten by this guy. If this guy were stewed, I wonder how delicious it would be.

Xu Changping thought about what he had to do tonight, and watched it swim away reluctantly before continuing to dive.

It didn't take long for Xu Changping to dive to the bottom of the lake. Through his glasses, he looked at the lake bottom that was in full view. For a moment, Xu Changping wondered if he had guessed wrong.

Based on the principle that since he was already here, Xu Changping swam to the lake and prepared to take a walk underground along the lakeside to take a look.

He had not walked 20 meters when he heard the alarm of an underwater metal detector in his headphones.

Xu Changping fumbled around nearby and fished out something that looked like an incense burner. After he put it into the system space, the underwater detector stopped ringing.

Xu Changping walked halfway along the river bank and came across a lot of broken bronze artifacts. He didn't know the exact year of them, so he put them all into his space.

“Beep, beep…beep, beep.”

The detector sounded again. Xu Changping turned it off manually and then concentrated on searching the area nearby.

After searching for a long time, Xu Changping found nothing.

Is the detector broken?

No!

Xu Changping turned the detector back on, narrowed the detection range, and began searching carefully.

After a while, Xu Changping heard the detector beeping continuously towards a moss-covered stone.

"What is this stuff."

Xu Changping turned off the sound, reached out to pick it up and take a look.

Ok?

So heavy?

Could it be a large piece that was sticking out?

Xu Changping put the underwater flashlight in his other hand into the space and exerted force with both hands.

Wave~~

Xu Changping saw that after he pulled the stone out, the hole left behind began to absorb water frantically.

His heart skipped a beat:

"Shit, no way, did he make the secret room leak?"

Just when he was thinking of some way to remedy the situation, the wall next to him suddenly split apart.

I don’t know why, but the water didn’t flow in from the cave entrance. Instead, it formed a water curtain cave.

I took out the underwater flashlight again, turned it on and shone it inside, and saw that it was empty, with nothing in it.

Xu Changping thought about it, took off his two flippers and put on a pair of slippers. He was not afraid of the lack of air circulation inside even though he was wearing an oxygen mask, so he just walked in.

After walking for a while, a huge stone door appeared in front of him.

After observing carefully for a while, Xu Changping found that the stone gate was smooth, which made him feel like he had no idea where to start.

He couldn't help but frown and set the detector's range to the maximum. As he expected, a series of warning sounds rang out.

After confirming that there was indeed something inside, Xu Changping could only ponder over the stone gate.

After carefully observing the walls around the stone gate, Xu Changping began to search inch by inch from the bottom.

Have it.

Soon he touched a somewhat movable stone in a hidden place in the lower left corner of the stone gate.

When he pried it open casually, a small black hole appeared in front of Xu Changping's eyes.

Haha

Xu Changping smiled silently. It seemed that this should be the keyhole.
