Through the magic circle, Ye Chu saw the situation with his heavenly eyes. It turned out that there was a huge black castle in the mountains, and there were some black-robed men in the castle at this time.

The castle covers an area of ​​about a hundred miles, and the highest iron tower in the middle is thousands of feet high. However, the castle looks a bit weird, and it is as dark as ink on the outside but you can't see anything inside.

"What is this?" Ye Chu asked Wang Kai.

Wang Kai said: "This castle was created by the lord himself. It is said that it was made of meteorites outside the sky. Even if it is a strong holy sword, it cannot be slashed at all..."

"What's inside?"

"There is nothing special inside, just some large fire veins and some mysterious places that we can't enter..." Wang Kai thought of it and said, "If the Lord of the Mansion comes to the branch hall, he seems to enter a forbidden area. If he doesn't know what is there, we can't enter and observe..."

"Okay, then let's go there and take me in." Ye Chu also felt the strangeness of this castle.

Wang Kai said awkwardly: "Mr. Ye, I can't take you in now. I will only be allowed to come here once every five years. If I go there now, it will definitely arouse their suspicion."

"So that's what it is..."

Ye Chu didn't expect that the organization of their Demon Palace would be so strict. He thought for a while and said, "Forget it, I'd better take you in. I'll be smart after I wait..."

"good……"

Ye Chu flashed and took Wang Kai to the magic array outside the castle, and directly pushed it in with the green lotus, without causing any abnormal movements in the magic array.

They came to the outside of the castle successfully. Several men in black robes happened to pass by here, but they did not find them. They successfully arrived in front of a huge gate at the bottom of the castle.

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

Ye Chu looked at the door and it was indeed a bit strange. It seemed that there was a magical force suppressing this place. This force reminded Ye Chu of the power of the alchemist's magic array.

"Mr. Ye, 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 that looked like iron. There were a lot of weird runes on the surface, and he couldn't recognize what was branded on it.

Wang Kai seemed to have no idea of ​​the meaning of these runes. At this time, two men in black robe walked over from a distance, preparing to open the door from here and enter the castle.

"Mr. Ye, these two are the two deputy team leaders of this branch..." Wang Kai was shocked and reminded Ye Chu.

He was afraid that the two deputy team leaders would appear, which would cause unnecessary trouble.

Ye Chu was unmoved at all. He saw the two of them coming to the door without any notice. One of them took out the pass token, and Ye Chu took Wang Kai and followed him in immediately.

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

The four walls of the passage are shiny iron walls, which look extremely smooth and not high, only more than two meters away, making it a bit depressing to walk in it.

"Why did those people in the imperial capital not respond? You need to send someone to find out this matter as soon as possible and report to the Lord of the Black Mansion..." Two men in black robe walked into the passage, and one of them said a little depressed.

"Yes, you see who should send to this matter?" asked another person.

"Send a small team to go there. I think it's not a big deal. After all, we went to the palace to see it not long ago. There is a holy-level magic array created by the Lord of the Palace. There are more than 20 people guarding it. There should be no big problems..."

"But I heard that the old emperor and Lian San have disappeared for a while. I wonder if something happened to them?" Another person worried.

The man said, "This matter is indeed a bit strange. If Refining San is obsessed with refining alchemy, the emperor is confused. However, the emperor is also a person at the peak of the quasi-saint. If he had not met a saint, he would have been afraid that nothing would have happened."

"That's true..."

The other person thought about it and found that there were not many saints in the love realm and would not be so easily killed. Moreover, the emperor was the largest leader of the royal family, representing a large-scale force, so how could anyone kill him?

The two of them didn't say much, and soon walked to the end of the passage and came to the front of a black iron gate. They took out a silver pass token and pressed it on the black gate. The black gate slowly opened.

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

This heat was too strong, a bit like the earth-center firepower he had gone to the center of the earth to look for the golden spirit fruit when he was on Biling Island.

The black gate opened, and Ye Chu sneaked into it. Only then did he realize that the inside of the castle was like this structure.

There are some small rooms around, and there are a large number of alchemists inside, who are refining alchemy. In addition, some areas are blocked, which he cannot see with his heavenly eyes.

But what is most impressive is that there is a winding fire vein under the ground inside the castle. This fire vein is black. Those alchemists rely on this fire vein to refine alchemy.

"Mr. Ye, this matter is a bit strange. I came here five years ago. At that time, there were no alchemy rooms and alchemists. These alchemists seemed to be a little different from us..." Wang Kai frowned and secretly sent a message to Ye Chu.

Ye Chu nodded. These alchemists were indeed a little different. At least they did not have any strong hostility in their eyes, unlike those like Wang Kai who practiced with magic stones.

Although they were all wearing black robes, these people did not wear masks. Ye Chu could see from their eyebrows that these people seemed to be nothing special, nor were they ghosts.

However, the pill they were refining made Ye Chu very curious and wanted to know what pill it was.

At this time, the two men in charge of the affairs also walked over and came to an alchemy room first. When the alchemy man saw the two coming, he immediately wanted to stop the alchemy work in his hand.

One of the managers waved his hand and said, "Don't worry about us, continue your alchemy!"

"Yes, sir!" The alchemist's cultivation is not as high as Wang Kai and the others, and it is about the ninth level of the sect. He immediately continued to refine the alchemy and added a powdery herb to the alchemy furnace. A rich fragrance immediately emerged from the furnace.

"Um……"

"good……"

Both the officials praised 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. If you work harder, wait until you have refined this furnace pill, I will ask you for me to the Lord of the Mansion on your behalf..."

"Thank you, my elders, I am very grateful..."

The alchemist looked very excited, as if he had picked up something to eat, and he was very excited.
