There were quite a lot of young men, all twelve sets. Chen An gave the young men twenty-four black crystal stones.

Just as he was about to leave, the young man said, "I have another killing weapon here. With your unfathomable cultivation, I'm afraid you can kill a Saint Realm expert with one strike. I wonder if you're interested?"

Chen An was naturally interested and asked the young man to take it out and have a look.

It was a black sphere, containing a power that made Chen An feel a little uneasy.

Staring at the black ball: "What is this?"

“This is the Hundred-foot Netherworld!”

"How do I use it?"

"There is a bump here. Just press it down and then throw it directly at the enemy. Unless he is a strong man in the Saint Realm Returning to One Stage, he will definitely die!" The young man's eyes were burning.

Chen An was skeptical: "Is it really that powerful?"

"Of course, anything produced by our sect must be top quality!"

"What sect are you from?"

"The Ghost Gate hidden weapon is unparalleled!" The young man said, seeming a bit arrogant.

"How many black crystal stones?" Chen An was indeed tempted.

"Ten black crystal stones will be enough."

Cheap!

It’s really cheap.

Chen An suddenly had a simple feeling, and felt that the more he looked at this young man, the more he liked him.

"Okay, I'll buy it. Do you have any other treasures? Maybe I'll buy more!"

The young man shook his head: "The most powerful one is this Hundred-foot Netherworld, there is nothing else. I just came to the polar region and I don't have any black crystals to use, so I had to sell it."

Chen An could see it without the young man saying it himself.

Then, he took out ten black crystal stones and bought the hundred-foot Netherworld.

The young man said seriously, "Don't try this lightly. This thing can only be used once!"

"OK!"

Not long after, Chen An and his group returned to the edge of the chaotic city.

Tan Tai Wushuang, Lin Hai, He Yu, Yang Yi, and Gu Qingyi, the master and apprentice, all exchanged some black crystal stones at Tianyi Tonghao.

After all, the black crystal stone is too important, so we have to prepare some.

What Chen An didn't expect was that when he exchanged the thousand-year-old spiritual herb for black crystal stones, one plant could only be sold for twenty black crystal stones.

There is a world of difference between it and miracle medicine.

But there is no way. People who have experienced the polar regions have higher standards and simply look down on the thousand-year-old spiritual herbs.

So no one wants to buy it. It seems that Tianyi Tonghao is also going to buy it here and then sell it to the Shenzhou mainland.

However, what surprised Chen An was that Gu Qingyi actually used a pill to exchange for two thousand black crystal stones.

One magical medicine costs only one thousand, but this girl can sell one pill for two thousand, which shows the value of this pill.

Chen An immediately wanted to see it: "What kind of elixir are you selling? Do you have any more?"

Gu Qingyi's voice was unusually gentle: "It's because I sold the Xuanhuang Pill you returned to me last time!"

Chen An never expected that the Xuanhuang Pill would be so valuable.

Then Chen An shamelessly asked if he could apply the rare poison Gu Qingyi gave him on the arrows.

Gu Qingyi directly said: "Aren't you sure that you have come into contact with a little bit of poison?"

Chen An frowned: "It should be okay if I'm careful, right?"

"Can it? This poison can even corrode the protective spiritual energy of the Saint Realm. Otherwise, how do you think it can kill the Saint Realm?"

Gu Qingyi's words immediately disappointed Chen An, but at the same time he was also shocked. The poison in his sleeve was so powerful!

However, Chen An still distributed the twelve sleeve arrows to other people for use in the Saint Realm. They were powerful and were said to have considerable killing power against the Saint Realm.

But at this moment!

He Yu was very surprised: "Your Majesty, this is a ghost gate hidden weapon!"

Chen An heard the young man say that it was a Ghost Gate hidden weapon, but he was just wondering why He Yu was so surprised.

"It's a ghost gate hidden weapon, what's wrong?"

He Yu's eyes brightened: "Your Majesty, this Ghost Gate hidden weapon was once unrivaled, but Ghost Gate was destroyed many years ago. How come there are still people from Ghost Gate?"

However, Yang Yi of the Yang Family said, "The Ghost Gate was destroyed, but perhaps its unique hidden weapon crafting was passed down. I even heard that Ghost Gate hidden weapons once appeared in the Dragon Palace!"

Hear the word Dragon Palace!

Chen An is sensitive, after all, it is a force that wants to kill him.

Could it be that the guy followed me in?

Then, Chen An narrowed his eyes and took out the black ball.

"Can you see the clues of this thing?"

When everyone saw the black ball in Chen An's hand, they were all a little confused.

It seems that there is nothing special about this black thing.

But at this moment, Ji Yu walked in: "This thing is the Hundred-foot Netherworld, it has great lethality!"

Chen An suddenly felt relieved, it seemed that he had not been cheated.

Ji Yu took the black ball and took a look at it: "Yes, it is the Hundred-foot Netherworld. It is indeed a very powerful hidden weapon of the Ghost Gate. However, you need to be careful when using this thing!"

"Seventh Uncle, what do you mean?" Chen An frowned.

"When using this thing, you must be a hundred feet away, otherwise you will be affected and die!"

Chen An's eyes flashed coldly: "That guy didn't tell me this, Huang Ji, Duan Chi, Yu Xing!"

"I'm here!"

Three people responded.

"Go to Tianyitonghao and catch that guy!"

Chen An was very suspicious that the guy had deliberately sold Baizhang Youming to him so that he could kill himself when he used it!

If this is true, then this person must be from the Dragon Palace!

But at this moment!

Ji Yu snorted coldly: "Don't go. If he really has some evil intentions, he will wait for you to go. But this thing is indeed a good thing. I guess even those in the Saint Realm and the Enlightenment Realm can't withstand its power!"
