At this time, in front of Qin Wuji, there was a gate that shone brightly.

Looking at this glittering door, Qin Wuji felt like his saliva was about to flow out.

Because, this door is actually made of diamonds!

"Are you Hidden Dragons so rich? Even the doors are made of diamonds? Qin Wuji asked in great surprise.

"Diamond, also known as diamond, is the hardest stone in nature, and even a bullet cannot penetrate it. Using it as a door can greatly improve security. Murong Yun explained.

Diamonds do the door? "Hidden Dragon" is really rich! Qin Wuji thought silently in his heart.

Murong Yun quickly entered a long list of complicated passwords, and the thick diamond door quickly opened.

When the door opened, it turned out to be a luxurious elevator inside, which could accommodate about five people.

At Murong Yun's signal, Qin Wuji walked into the elevator, and then Murong Yun closed the door.

"Which floor do you want to go to?" Murong Yun pointed to the button on the elevator and asked.

Qin Wuji immediately looked over at this time, and it turned out that there were five buttons on the elevator, and there were some words written next to the buttons.

The button on the first floor reads "Intelligence"; The button on the second floor reads "Weapon"; The button on the third floor reads "Medicinal Herbs"; The button on the fourth floor reads "Metal Raw Materials"; The button on the fifth floor reads "Special Items".

"Fourth floor!" Qin Wuji said decisively.

Murong Yun glanced at Qin Wuji with some surprise, the first thing ordinary people look at when they come here is basically the "intelligence room" on the first floor, but he didn't expect Qin Wuji to choose the "metal raw material warehouse" on the fourth floor.

After Murong Yun pressed the button, the elevator quickly stopped on the fourth floor.

After the elevator door opened, Qin Wuji couldn't wait to walk out, and was immediately stunned.

On the fourth floor is a huge room, densely packed with many boxes, each with a white sign in front of it, which seems to introduce the contents of the box.

Qin Wuji immediately walked over and immediately looked at a box directly in front of him.

He looked at the white sign on the front of the box and saw that it read: Mithril, a precious metal, a metal that can be made into steel, but light as a goose feather.

Immediately after, Qin Wuji looked at the second box, and the white sign on it read: Extraterrestrial Meteorite, a mysterious metal that can make indestructible weapons and unbreakable armor.

Good stuff! Although he had only looked at two of the boxes, Qin Wuji felt that the materials in these two boxes were all good things.

When Qin Wuji looked at the third box, his eyes immediately widened.

Because the white sign in front of the third box actually reads: Millennial cold iron, precious metal, can be used to make flying swords.

Millennial cold iron! It's actually a thousand-year-old cold iron!

Qin Wuji never expected that he would see such a thing as a thousand-year-old cold iron in this place!

As mentioned above, the Millennial Cold Iron is the raw material for crafting flying swords, and the refiners of the Heavenly Continent can use it to craft flying swords.

The flying sword is one of the most basic and popular cultivation weapons, and it is very popular in the Heavenly Continent.

However, the thousand-year-old cold iron used to create flying swords is very rare, and it usually only appears in large-scale auctions, and the price is also very expensive.

Qin Wuji saw the thousand-year-old cold iron here at this time, which naturally gave him a very peculiar feeling.

Qin Wuji subconsciously opened the box containing the thousand-year-old cold iron in front of him, wanting to take a look at the material that was also very rare in the Heavenly Continent.

But to Qin Wuji's surprise, when he opened the box containing the thousand-year-old cold iron, it was actually empty!

"Where's the stuff?" Qin Wuji immediately asked.

"I forgot to tell you just now, the materials in this are the essence of thousands of years collected by Huaxia. But some of them have been used up, and only a few remain. The chest in front of you is empty, which naturally means that the materials inside have been used. Murong Yun explained embarrassedly on the side.

Used up? Qin Wuji's mood at this time was like accidentally winning five million, but he suddenly found that his prize ticket had expired!

He was already very shocked when he stumbled upon the thousand-year-old cold iron here, but then he found out that the thousand-year-old cold iron had actually been used, which really made him cry and laugh.

Forget it, anyway, I don't need a flying sword at the moment, and it doesn't make a difference if I have it or not. Qin Wuji silently comforted himself in his heart.

Then, Qin Wuji acted as if he hadn't seen the third box and walked directly to the next box.

When he saw the sign on the front of the fourth box, his face immediately showed surprise.

The sign on the front of the fourth chest reads: Empty Stygian Stone, whose purpose is unknown, seems to contain the mystery of space.

Empty Stygian Stone! This is actually the Empty Immortal Stone he has been looking for!

Qin Wuji became excited at this time, he didn't expect to really see the material he was looking for here, the Void Immortal Stone was the best material for refining the Space Ring!

Qin Wuji took a deep breath, and then opened the box in front of him with some trepidation.

When he saw an egg-sized hollow stone lying quietly in the box, his face immediately showed surprise.

"Great!" Qin Wuji directly grabbed the Void Stone excitedly, and the expression on his face was extremely excited.

"Selected?" Murong Yun saw Qin Wuji's excited expression and asked lightly.

"If you choose it, you want this piece!" Qin Wuji clenched the Void Immortal Stone and nodded violently.

"Won't you look at the others? You know, there's a lot of good stuff in there. Murong Yun asked with a smile.

Qin Wuji immediately turned around and looked at the dozens of boxes behind him, with a longing expression on his face.

"Can I take more?" Qin Wuji looked at Murong Yun with a pleading expression and asked.

"Everyone who joins Hidden Dragon can only take one thing inside, that's the rule." Murong Yun said coldly.

"Then don't look at it! I'm afraid that after I finish reading it, I can't help but ransack this place. Qin Wuji resisted the impulse in his heart and said firmly.

Murong Yun smiled after listening to Qin Wuji's words and led the other party out of here.

On the elevator, Qin Wuji was very careful to hide the Void Immortal Stone, and he felt indescribable joy in his heart.

He didn't expect that he was so lucky to find the Void Immortal Stone here. After he goes back, he will be able to refine the space ring immediately, and it will be much more convenient when the time comes.

"Since you took our things, then you are officially joining our Hidden Dragon?" After Murong Yun left the treasure vault with Qin Wuji, he said to him.

Qin Wuji's hands were short at this time, and he was embarrassed to refuse again, so he nodded, indicating that he agreed.

"I told you in advance, since you have joined the Hidden Dragon, then you must abide by the rules. If you dare to betray, then you will be hunted down by the two kings! Murong Yun looked at Qin Wuji and said solemnly.

Murong Yun's words startled Qin Wuji, Nima, betraying the "Hidden Dragon" would actually be hunted down and killed by the two kings, this is too terrifying.

Even if in the Heavenly Continent, being hunted down and killed by two strong men in the Jindan period is basically more than lucky, let alone on the earth?

Qin Wuji couldn't help but swallow his saliva, feeling that he was under tremendous pressure.

"Okay, wait a minute, let the ghost doctor take you to register the information, and you will officially become a member of the Hidden Dragon. Old man, I have a lot to do, so I'll go first. After Murong Yun saw that Qin Wuji was intimidated by himself, he smiled faintly and then said.

Qin Wuji stood in place, his feelings were a little low, he felt as if he had been fooled, and inexplicably joined the "Hidden Dragon".

"I forgot to tell you, if you can make great contributions to the country, then you can go to the treasure house and choose any thing, I believe in your ability, do it well." Murong Yun walked halfway and suddenly turned around and told Qin Wuji such a news.

Hearing his words, Qin Wuji, who had a depressed face, immediately raised his head, and a hint of surprise flashed in his eyes.

He didn't expect that "Hidden Dragon" would have such a benefit, as long as he could make great contributions to the country, he would have the opportunity to go to the treasure house and choose one thing at will, which was simply wonderful.

Don't worry, I'll empty you one day sooner or later! Qin Wuji looked at the deepest diamond gate and silently swore in his heart.

"Brother Qin, please come with me and register your information." Just when Qin Wuji was making great ambitions, the ghost doctor suddenly spoke.

Qin Wuji looked at the ghost doctor with the mask and silently followed behind the other party.

"Brother Qin is a good cultivator, I don't know what kind of ability you are?" The ghost doctor walked in front and suddenly asked.

He hadn't figured out what kind of abilities Qin Wuji possessed until now, so he was naturally very curious.

"Anomalous ones? I'm not. Qin Wuji replied.

"You're not a paranormal? So how did you injure Thor? The ghost doctor stopped and asked Qin Wuji.

"I'm a cultivator, and I'm hurting him with a spell." Qin Wuji replied truthfully.

"Cultivator? Are you a cultivator? The ghost doctor suddenly asked with some excitement.

"What's wrong? Is there a problem? Qin Wuji asked with some confusion.

"No, no problem. However, I suggest that you still call yourself an ability, and then think of a random ability, which is better for you. The ghost doctor's voice quickly returned to normal, and he said lightly.

Qin Wuji looked at the ghost doctor with a puzzled expression, but unfortunately the other party was wearing that grimace mask, and he couldn't see the other party's expression clearly.

Although it was very strange in his heart, Qin Wuji still decided to listen to the words of the ghost doctor and follow the customs of the locals, and regarded himself as a supernatural person.

Immediately after, the ghost doctor did not continue to talk to Qin Wuji, and silently led him to his destination.

Qin Wuji didn't notice that when the ghost doctor heard him say that he was a "cultivator", his hand suddenly trembled, presumably his heart was not as calm as it appeared on the surface.
