Through the magic circle, Ye Chu saw the situation with the eye of heaven, it turned out that there was a huge black castle in this group of mountains, and there were some black-robed people in the castle at this time.

The castle covers an area of about 100 miles, and the tallest iron tower in the middle is thousands of zhang high, but this castle looks a little weird, and the outside is as dark as ink but you can't see anything inside.

"What kind of place is this?" Ye Chu asked Wang Kai.

Wang Kai said: "This castle was created by the lord of the mansion himself, and it is said that it was built with meteorites from outside the sky, and even the strongest holy sword cannot be used to split it from the outside......

"What's in there?"

"There is nothing special in it, just some large fire veins, and some mysterious places, we people can't enter it...... Wang Kai thought about it and said, "If the mansion master usually comes to the altar, it seems that he will enter a forbidden area in it, I don't know what is in it, we can't enter the observation ......"

"Okay, then we'll go there and have a look, and you take me in. Ye Chu also sensed the strangeness of this castle.

Wang Kai said embarrassedly: "Ye Shao, I can't take you in now, I will only be allowed to come here once every five years, if I go over now, it will definitely arouse their suspicion." ”

"That's ...... so"

Ye Chu didn't expect that their Demon Palace, the organization would be so strict, he thought for a while and said, "That's it, I'll take you in, and I'll be smarter when I go in......"

"Good ......"

Ye Chu's figure flashed, and he took this Wang Kai to the magic circle outside the castle, and directly used the green lotus to enter it, without causing any changes in this magic circle.

They came to the outside of the castle along the way, and a few black-robed men happened to pass by, but they didn't find the two of them, and they came to a huge gate at the bottom of the castle.

"If you want to enter here, you must clear the token......" Wang Kai secretly reminded Ye Chu.

Ye Chu took a look at this door and found that it was indeed a little weird, as if there was a magical force suppressing here, this power made Ye Chu think of the power of the alchemist's magic circle.

"Ye Shao, this is my token...... Wang Kai handed over his clearance token to Ye Chu.

Ye Chu looked at the token in his hand, it was a black token like iron, there were a large number of strange runes on the surface, and he couldn't recognize what it meant.

Wang Kai didn't seem to know the meaning of these runes, and at this moment, two black-robed people came from a distance, ready to open the door from here and enter the castle.

"Ye Shao, these two people are the two deputy leaders of this altar......" Wang Kai was shocked and reminded Ye Chu.

He was afraid that the two deputy team leaders would find out about the two and cause unnecessary trouble.

Ye Chu was unmoved, only to see that these two people came to the door, and did not notice anything, one of them took out the customs clearance token, and Ye Chu and Wang Kai immediately followed in.

The gate closed heavily, and Ye Chu came to the castle, and the first thing that caught his eye was a black passage.

The four walls of the passage are oily iron walls, which look extremely smooth, and they are not high, only more than two meters, and people look a little depressed when they walk in them.

"Why didn't those people in the imperial capital respond, this matter needs to be sent to find out, and report to Lord Heifu......" The two black-robed people walked into the passage, and one of them said a little depressed.

"yes, who do you think is the right person to send on this?" asked another.

"Send a team to go, I don't think it should be a big deal, after all, we went to the palace not long ago, there is a saint-level magic circle personally distributed by the lord of the mansion, and there are more than 20 people guarding it, so there shouldn't be any big problems......"

"But I heard that the emperor Lao'er, as well as Lian San, have disappeared for a while, I wonder if something happened to them?" said the other worriedly.

This human: "This matter is indeed a bit strange, Lian San is obsessed with alchemy, and the emperor Lao'er is also confused, but the emperor Lao'er is also a person at the peak of the quasi-saint, if he doesn't meet the saint, I'm afraid there will be nothing." ”

"That's ...... too"

The other person thought about it, there are not many saints in the love realm, and they will not be poisoned so lightly, not to mention that the emperor Lao'er is still the biggest leader of the imperial family, representing a super power, how can anyone kill him.

The two didn't say anything, and soon walked to the end of the passage, and came to a black iron door, and at the same time took out a silver clearance token and pressed it on the black door, and the black door slowly opened.

A burst of heat rolled in, and even Ye Chu, who was hiding in the void, was shocked.

This heat is too strong, a bit like the geocentric firepower that he used to go to the center of the earth to find the golden spirit fruit when he was on Biling Island.

The black door opened, and Ye Chu followed him into it, only to find out that the interior of this castle was like this.

Surrounded by some small rooms, there were a large number of alchemists inside, who were alchemizing in them, and there were also some areas that were blocked, and he couldn't see them with his heavenly eyes.

But the most impressive thing is that under the ground inside the castle, there is a winding vein of sky-high fire, this vein of fire is a black fire, and those alchemists rely on this vein of fire to carry out alchemy.

"Ye Shao, this matter is a little strange, I came here once five years ago, and there were no alchemy rooms and alchemists at that time, these alchemists seem to be a little different from us......" Wang Kai frowned, and secretly transmitted Ye Chu.

Ye Chu nodded, these alchemists were indeed a little different, at least there was no strong anger in their eyes, unlike Wang Kai, who cultivated with magic stones.

Although they were all wearing black robes, these people were not wearing masks, and Ye Chu could see from their eyebrows that these people didn't seem to be anything special, and they weren't ghosts.

It was the pill they were refining that made Ye Chu very curious and wanted to know what kind of pill this was.

At this time, the two black-robed people in charge also walked over, and first came to an alchemy room, and when the alchemists saw the two of them coming, they immediately wanted to stop the alchemy work in their hands.

One of the stewards waved his hand and said, "Leave us alone, continue your alchemy!"

"Yes, my lord!" The alchemist's cultivation was not as high as Wang Kai and them, and it was about the ninth level of the sect king, so he immediately continued the alchemy and added a powdered herb to the Dan furnace, and a rich fragrance immediately came out of the furnace.

"Hmmm......"

"Not bad......"

The two stewards both exclaimed with satisfaction, and one of them sighed: "I haven't seen you for a month, it seems that your furnace pill is about to succeed, and if you work harder, when you refine this furnace pill, this seat will ask the mansion master for merit on your behalf......"

"Thank you two adults, I can't thank you enough......"

The alchemist's expression was greatly lifted, as if he had picked up something to eat, and he was very energetic.
