The man carried Long Tan down the cave first, Yue Ya'er gave everyone a look, asking everyone to be more careful in the demon city, it seems that he already knows that Yue Ya'er is a human being, fortunately, Long Tan has a high prestige in the demon clan, no one dares to offend him easily, as long as Long Tan is here, they are safe.

Long Tan and the two went down for almost a minute, and there was a sound of knocking stones at the bottom of the cave, Yue Ya'er went down the hole, Long Tan instructed that the hole should be separated, and there were some holes in the hole that were only the size of a fingernail, and there were ' Blind Spirit' (Blind Essence is a kind of demon insect of the demon race, they have no eyes and mouth, only a nose, their strength is smell, the demon city raises this kind of insect on the cave wall in order to distinguish whether to mix in humans), although Long Tan has hidden their popularity, but Yue Ya'er is a demon hunter, and he still has a rune knife on his body, and Captain Li is a policeman, and his righteousness is stronger, compared to ordinary people,' The popularity is even stronger, if you get together in the hole, I am afraid that it will be smelled by the blind spirit, Long Tan also specially explained that they can't exhale hard, but exhale softly and slowly, so that it is not easy to leak the popularity of the body. The cave is very dark, and a small box of corpse wax will be placed every 5 meters (the candle is mixed with the corpse oil of the demon who has been walking for more than 300 years, and the wick of the candle is also made of the demon's bones, called corpse wax), which can be used for illumination. When the corpse wax burns, it will emit a green light, there is a faint air flow in the cave, the green fire is swaying in the hole, it looks very weird, and the smell is also very bad, just like a stinky sock that has not been washed for 100 years, ordinary people can faint after a few sips, but they are afraid of revealing their identity and have to endure it, and when they can't bear it, they take a deep breath and hold it until they can't hold it anymore and then breathe.

Captain Li was very curious about everything in the demon city, and heard Long Tan say that there was a 'blind spirit' in the cave, so when he went down to the cave, he paid special attention to the holes in the cave wall, the blind spirit was black, like a caterpillar, but it had no hair and no feet, and the largest was only half a knuckle long, and it looked like some small black dots from a distance. When Captain Li was observing the blind man in one of the holes, Pan Huanchen, who came down behind him, didn't step on it steadily, got some soil down, and fell on Captain Li's face, making him suck some soil into it, his nose was a little itchy, he fixed himself on the wall of the cave, and scratched his nose with one hand, and then scratched more and more, he realized that he might be sneezing, and hurriedly covered his nose and mouth with his hands. The breath from his nose was sprayed right on the body of a blind man.

At this time, the cave was very quiet, hearing the sound of Captain Li's sneezing, everyone stopped their movements and held their breath, observing whether there was any change in these holes in the cave, suddenly, everyone found that the fire in the cave was not so green, and added a little bit of red, and after a while, the red became more and more vivid and bright, and before everyone could figure out what was going on, Han Xu shouted for everyone to see the holes where the blind spirits lived.

It doesn't matter if you don't look at it, this look makes everyone's nerves tense.

Those red stars are blind spirits! At this time, the blind spirit's body had faded to black, his whole body was red, and he made a 'hiss' sound, which sounded very terrifying. Could it be that the blind spirits have smelled something strange, and this is a signal from them? As time passed, the red light emitted by the blind spirit's body became brighter and brighter, dyeing almost the entire cave red.

"Bud, what should I do now?" Captain Li panicked, he had never seen this kind of battle, and Long Tan said that this blind man was mysterious, he was afraid that his sneezing would cause everyone to lose their names.

"Don't panic, these blind spirits don't hurt anyone, everyone is stable." The man with Long Tan on his back spoke, his voice not loud, but everyone heard it clearly, as if he was standing next to everyone and talking. Hearing him say this, everyone did not dare to stay any longer, and they all quickened their pace, and after about 5 minutes, everyone descended one after another and reached the bottom of the cave.

Long Tan and the man had been waiting at the bottom of the cave for some time, and when they saw everyone coming down, the man grinned and didn't speak, his eyes swept over everyone's face, as if to confirm that there were several humans in it.

"Ancestor, let's go in." What everyone didn't expect was that the man didn't say anything, and turned his face to Long Tan with a signature flattering smile.

"Let's go, you guys," Long Tan's expression was very serious, as if he was saying to everyone, but in fact, he really told Captain Li, "Keep up, don't make any mistakes!" ”

After going down to the bottom of the cave, there is a larger cave, about more than 100 square meters, and the wall is no longer corpse wax, but a red candle lamp that looks a little luxurious and has a carved base, and some paintings are carved on the wall.

Han Xu felt novelty and took out his mobile phone to take pictures, he hadn't seen as much as Yue Ya'er in the Demon Treasure Book, he only recognized Long Tan in the whole mural, and the person walking in front turned around and urged him a few times, Han Xu originally wanted to take a panoramic view, but he was afraid that Long Tan would be angry and had to give up.

They walked for a few more minutes, and a door appeared, the door was originally there, but there was also a painting on it, so it couldn't be seen, but the painting on this door was very strange, it was not a demon, but a person, Yue Ya'er looked at the painting carefully, and suddenly covered her mouth in surprise, she didn't know this person, but she could know the magic weapon pinned to his waist, which was a rune knife.

Each demon hunting clan will make their own rune knife, each family's rune knife is painted with different patterns representing their own family, rich families will do some decoration on the handle, such as inlaid with a gem or crystal, the rune embedded in the tip of the knife is not the same, the rune knife of the Yue family is embedded with a blue crystal at the handle, and there is a circle of silver around the crystal, which is the characteristic of the rune of the Yue family, like the Inner Mongolia Nali family that Yue Yaer knows, the rune knife is made like a sickle, and a wolf head is carved out of the sword...... But she couldn't tell which family the person in the painting belonged to, and there was a red stone embedded in the handle of his rune knife, and she couldn't tell if it was a gem, and the word 'clothes' was engraved on half of the blade, and I don't know what it represented.

The leading man took a string of demon markets from his neck, and put it on the position of the man's eyes in the mural, as soon as the key touched the mural, the man in the painting changed, his eyes became completely black, the position of the eye opened and retreated, and a hole appeared, which matched the shape of the key, he inserted the key and twisted it half a circle to the left, and then pulled it out and took a few steps back, and they also learned from him to take a few steps back, and the door began to rise slowly, and after a minute, it was completely raised.

As soon as the door opened, a long stone corridor appeared, and they heard the sound of a lively market at the end of the corridor, presumably it was the demon market.
