The inside of the small door was pitch black, and Poplar searched for a long time on the wall of the doorway, but he couldn't find the electric light drawstring.

However, after waiting for a while, his eyes had gradually adjusted to the darkness, and by the light in the cellar at the entrance, Poplar could roughly see the situation inside.

The cellar is deeper than the outside, and its height should be more than three meters.

The inside was about the same size as the cellar outside, and the corners of the walls on either side were full of black things.

And in the middle of the cellar, suddenly there was a very high utensil, which reached the top of the cellar to the top of the cellar.

"What is this, it looks so strange!" Ding Lingling said.

"It's too dark to see clearly, or Lingling, you wait down there, and I'll go up and find a candle or a flashlight!" said Poplar.

Ding Lingling agreed, she often went in and out of the ancient tomb, so naturally she would not be afraid of the old man's corpse outside.

Poplar didn't think she would be afraid, but just looked at it and felt that there would be no other danger in the cellar, and the tanuki cat also followed Ding Lingling's feet, so Poplar walked boldly to the cellar with confidence.

The height of the cellar mouth is more than two meters, and there are no steps, but there is a wooden ladder on one side of the cellar entrance, and you only need to move the ladder to go up and down.

But Poplar didn't use a ladder at all, so he jumped out.

No candle or flashlight was found in the bedroom, so Poplar went to the living room again, and found a flashlight in the drawer of the living room.

Poplar returned to the cellar with a flashlight, but still jumped straight in.

Ding Lingling waited at the door of the cellar inside, waited for Poplar to approach, and shone a flashlight inside.

Because the cellar inside was deeper, there were several steps in the small door, and the two of them walked down the steps, carefully examining the extremely tall object in front of them.

Now that I could see it clearly, I realized that the object did not reach the top of the cellar. In fact, the object was only more than a meter tall, and it looked quaint and exquisite, much like another antique.

The lower part of it has three legs with a height of more than 40 centimeters, and the round ones above the legs are like a large copper furnace. The top of the copper furnace has a lid attached to the top of the lid and an iron cylinder.

It was this iron cylinder that reached up to the top of the cellar, and it was clearly a modern preparation, not an original accessory to the object.

Looking up at the iron cylinder, it seemed to be inserted directly into a round hole in the top of the cellar.

Poplar couldn't help but take a breath, and turned his head to look at the black objects around the cellar, only to realize that they were all charcoal.

And in the lower part of the artifact, which resembles a copper furnace, there is also a round groove, and there is a lot of black ash in the circular groove.

Bai Yang turned his head to look at Ding Lingling, Ding Lingling's eyes also showed surprise, almost in unison, and the two of them said three words at the same time: "Alchemy furnace?"

"Not bad!" Ding Lingling nodded, "This is very similar to the alchemy furnace of ancient Taoism, and these charcoal are naturally used for alchemy!"

She said as she turned to the back of the copper furnace.

Poplar followed and found a small closed door at the back of the furnace with a small pull ring on it.

Ding Lingling tried to pull the small pull ring, and the small door opened immediately.

Ding Lingling reached in and took out a few marble-sized black pills from inside.

"Sure enough, it's an alchemy furnace!" Ding Lingling said, looking at the few pitch-black pills in her hand, "According to my estimate, these pills may not be longevity pills, but they are likely to be poisonous." The reason why the old man sitting outside died was probably because of eating these longevity pills that he thought he had cultivated!"

"That's right!" Bai Yang nodded, "It's probably the poison contained in these pills that keeps the old man's body from rotting!" But I'm very surprised that charcoal burning is poisonous, he burned charcoal in this closed cellar to make alchemy, he should have been poisoned to death a long time ago!"

"Maybe this cellar isn't as closed as we thought!" Ding Lingling said, looking up and down the cellar carefully.

Poplar followed and looked around, and soon found that at the top of the cellar on the left and right sides of the cellar, two fine gauze nets were installed, and there seemed to be a round hole in the net.

And under the mesh, a small switch is also installed. Poplar walked over and pulled the switch pull rope, and immediately there was a whirring sound, and it seemed that there was also a small ventilation fan installed in the ventilation hole behind the gauze.

"No wonder charcoal can be burned in this cellar for alchemy, which is originally equipped with a ventilation fan!" said Bai Yang.

"Yes!" Ding Lingling nodded, "There is no sale of such a small ventilation fan on the market until now, not to mention that this house must have been built for decades, I estimate that these two ventilation fans were designed and manufactured by the dead old man outside!

"I don't think it's unusual, he must have set up a very clever mechanism at the entrance above, and I want to say that the technology of making ventilation fans is simpler than ordinary tomb mechanisms!"

Ding Lingling nodded in agreement, and said, "So I'm even more curious, what is the identity of this old man, why does he have so many antique collections, and he understands ancient alchemy techniques?"

"I don't think he necessarily knows the alchemy technique, otherwise he wouldn't have practiced the pill to eat himself to death!" Bai Yang said, suddenly his heart moved, and he was a little stunned.

"What's the matter, did you think of something?" Ding Lingling asked immediately.

"I'm wondering if this old man not only sets up mechanisms, but also makes ventilation fans, so is it possible that he is an inverted fighter himself? Could it be that all the collections in this cellar were dug up by him from the ancient tomb? Could it be that he once dug up a certain Taoist tomb, found this alchemy furnace from the Taoist tomb, and obtained the alchemy method and even the elixir formula at the same time? He thought it was an elixir, so he dug the cellar and hid here to practice the elixir?"

Bai Yang's words were all interrogative sentences, but Ding Lingling nodded again and again after thinking about it carefully, and said: "I think your inference is very reasonable! It's just that we entered the house privately, and this old man died inexplicably, we must call the police first, and we can't investigate and search here without permission!"

"Yes!" Poplar nodded, "Then let's go up first, I'll guard here, you go back and report to Uncle Ding, and see what Uncle Ding does!"

Ding Lingling nodded, and the two of them exited the alchemy cellar together.

Ding Lingling picked up the tanuki cat, Poplar placed the wooden ladder at the mouth of the cellar, Ding Lingling first held the kitten and climbed up the wooden ladder, and Poplar followed.

Ding Lingling suddenly had a whim, turned around and asked with a smile: "Do you think that old man will have an immortal medicine list, he is the elixir refined according to the immortal medicine list?"

"How is it possible?" Bai Yang couldn't help laughing, "There can't be such a coincidental thing in this world, we are investigating the immortal pill and the immortal pill list, and there is a person refining the immortal pill here! Of course, this old man must want to refine the immortal medicine, but the medicine list in his hand will definitely not be true!"

"That's right!" Ding Lingling nodded and smiled, glancing at Bai Yang, "After all, we have repeatedly confirmed the medicinal properties of the immortal elixir, it is impossible to poison people, but it does have a miraculous effect!"

The glance she glanced at Poplar was meaningful, and Poplar naturally understood what she meant, so he smiled at her.

I didn't want to just walk out of the door of the room, Ding Lingling suddenly said another sentence.

"You say...... Those alchemists we met, they can live to be two hundred and fifty years old if they eat two immortal pills, and if you eat half of them with Tie Niu, will you live to be over 100 years old?"

Poplar had never thought about this question, and she couldn't help but be stunned when she suddenly asked.

Ding Lingling smiled, pushed open the courtyard door with the tanuki cat in her arms and went out.

Poplar stood in the courtyard, his heart fluctuating for a moment, and he didn't know what he was thinking.

Fortunately, it didn't take long for Ding Sicheng to arrive with Xiang Aiguo and Ding Lingling, and said: "The police have been called, and the public security officers will be there soon! But I have already identified myself with them, we can do exploration first, and then just provide them with a detailed record!"

Poplar naturally obeyed the order, so several people re-entered the house to investigate carefully.

Ding Sicheng took Ding Lingling to the cellar below to investigate, while Bai Yang followed Xiang Aiguo to investigate inside and outside the room.

Soon the two of them found the location of the two vents of the alchemy cellar.

The two vents are cleverly designed, one hidden behind the kitchen tank and the other in the corner of the utility room.

What's even more ingenious is that the chimney of the alchemy furnace is directly connected to the kitchen chimney, and when the alchemy is underneath, the smoke will come out directly through the kitchen chimney, which will not arouse the suspicion of outsiders at all.

Soon the public security officers rushed over, and after doing the scene investigation, they were also very surprised by the corpse of the old man, according to the forensic doctor's words, he had been engaged in forensic work for more than 20 years, and had never encountered such a strange corpse.

So the public security officers took the body back to the public security bureau and made a detailed confession to Poplar Ding Lingling.

One of the criminal investigation section chiefs who led the team said a few words to Ding Sicheng in a low voice, and Ding Sicheng nodded again and again.

After that, the chief of the criminal investigation section left with the public security officers, while Ding Sicheng Baiyang and others stayed at the scene to continue to investigate and sort out those antique cultural relics.
