When the An Ding Si group arrived at the original tea processing factory, it was already past six o'clock in the afternoon. Fortunately, it was July, and the sun set relatively late.

The sun had not yet set, but it only made the dilapidated factory look even more desolate.

On the way here, Li Nan had contacted the "owner" of the tea factory more than once, but the man named Wang Cheng never answered the phone.

Although they couldn't contact the factory owner for the time being, the matter was urgent, so Li Nan took the lead and broke down the factory gate.

Inside the gate, weeds grew rampant, obscuring the path into the factory.

Li Nan drew his baton, identified the direction of the factory, and used it to clear a path through the weeds as he marched toward the factory.

"These weeds are growing so lushly!"

Looking at the shoulder-high weeds in front of him, Ma Jie couldn't help but sigh.

Yang Bairong, who had rural experience, sniffed the air and said, "There's the smell of chicken manure fertilizer here. It's a bit extravagant for a processing plant to use such good farmyard manure for its green belt!"

"You wouldn't realize it until you say so, but this chicken manure smell is really strong!"

Li Nan comes from the cherry blossom capital. Although she has never actually worked in the fields, she still has basic common sense.

Among farmyard manures, chicken manure has the strongest odor, regardless of its fertility.

"This is definitely unusual. Most farmers wouldn't choose this fertilizer. What were these people thinking?"

Qin Wen had been looking at the weeds in the factory area for a long time, and her rich experience told her that the growth of these weeds was not right!

Qin Wen had a vague guess in her mind, but she didn't say it out loud.

Upon reaching the factory gate, the ground had undergone simple hardening treatment, at least preventing weeds from growing.

The factory gate was tightly locked with iron chains. This time, without Li Nan's instructions, Ma Jie returned to the police car and took a hydraulic shear from the toolbox.

"Snap!"

With a sharp crack, Ma Jie cut the iron lock, pulled off the chain, and pushed open the long-sealed door.

It was already six or seven in the afternoon, and the room was pitch black as the lights were off.

Li Nan and his team put on gloves, shoe covers, and masks, turned on their police flashlights, and entered the dimly lit warehouse.

Yang Bairong tried turning on the switch near the door, and to his surprise, the light came on!

"The power company in this area is pretty good; they didn't cut off the power at all?"

Looking around at the empty factory, Li Nan thought, "I'm afraid this isn't thanks to the power company!"

Li Nan pointed to the roof, "I took a look before I got out of the car, and this roof is covered with solar panels!"

The factory is not large, only about a hundred square meters, and is divided into three rooms, one inside and one outside.

The two outer rooms were empty, with nothing inside.

Qin Wen and her colleagues from the Trace Evidence Department took fingerprints and other samples and examined them.

"No valid fingerprints were found; this area has been cleaned!"

Li Nan walked into the inner room, which was slightly smaller than the two outer rooms, measuring only five or six meters in length and width.

Unlike the other rooms, there was a square table in the center of the room.

There were several bags that looked like cement piled up in the corner.

Li Nan walked around the table, stomped her feet, and listened to the slightly different echoes, which gave her a guess.

Li Nan pushed the table aside, squatted down, and examined it carefully.

The seam is clearly visible; in the very center of the house, there is a fault about two meters long and one meter wide.

Li Nan's actions naturally attracted the attention of others, and Ma Jie and Yang Bairong were the first to run over.

"Master, what have you discovered?"

"This warehouse should have a basement; the entrance is right here!"

Li Nan remembered that this warehouse was originally used by Gao Siming to store tea.

It's not surprising that this processing plant has a basement!

The basement environment is relatively stable, and it is easier to control the temperature and humidity, making it very suitable for storing tea.

The seams in the floor were small, so Li Nan couldn't put any pressure on the ground directly. He got up and looked around.

Sure enough, near the light switch, there was a spot with a different color.

Yang Bairong followed Li Nan's gaze and saw it there. He walked straight over and, with a little force, lifted a small cover.

Inside, there is a red up-and-down switch embedded in it.

Yang Bairong flipped the switch, and after a pause of two or three seconds, the cover in the middle of the room slowly rose and rotated, revealing a basement entrance in front of everyone.

This time, Ma Jie ran quite fast. After the cover was opened, he rushed to the front and looked down!

The up and down switches seem to directly control the basement lights; now, standing upstairs, you can see the basement is brightly lit.

"Let's go down and take a look!"

"Wait a minute!" Qin Wen had noticed the situation earlier and came over with an air quality detector.

"Are you all crazy? You can't just go down to the basement like that! Let me check the air quality down there first!"

Fortunately, the test results were fine. Li Nan led the way, followed by Qin Wen and Li Na, and they went into the basement one after another.

The basement was estimated to be five or six times the size of the room. On one side, there were four large restaurant-style refrigerated freezers in a row, and on the other side, there was a fully equipped kitchen with various cooking utensils, cutting boards, knives, and two large, powerful stoves that were particularly eye-catching.

Above the stove, a complete fume filtration system was installed, but the exhaust duct led somewhere on the ground.

On the other two sides were the condiment storage area. Li Nan went forward to check and found that there were very few condiments left in the cabinet, and many of them showed signs of having been used.

Besides these, there were also several huge iron cages in the middle of the basement.
