The man at the stall next to him was the big, fierce-looking man who was in front of Gu Ding at the front desk. He recognized Gu Ding instantly.

Gu Ding looked down at his stall. It was the ax that he had taken to the front desk and had been appraised as "worthless" by the treasure appraisal robot.

"Does this guy really think this ax is worth a lot of money?" Gu Ding did not understand. He had always thought that the big man was deliberately causing trouble at the front desk, but now he had set up his stall in the tower. The tower charged a stall fee every day.

"Hey, kid, don't go!" Gu Ding stopped in front of his stall for a moment. He turned around and walked toward the next stall, but was stopped by the big man.

"What's the matter?" Gu Ding turned around, puzzled.

"I just wanted to ask you if the things you took for appraisal were also appraised as worthless."

"There's nothing wrong with my appraisal results." Gu Ding shook his head. He wanted to tell the man that it was not the problem with the treasure appraisal robot but the ax, but he held back.

"How is that possible?" The man looked down at his ax in disbelief. "It's something passed down from our ancestors. How can it be worthless?"

"Neptune, the treasure appraisal robot shouldn't be wrong, right? Have you seen his ax? "Gu Ding could not help but ask.

"I've roughly scanned his ax and didn't find anything special. The material composition of each part is clear at a glance, and the arrangement of each component can be seen clearly. To be honest, the workmanship of this ax is very average. " Neptune's evaluation of the ax was obviously not very high. "This guy was probably deceived by his family elders since he was young, and he's still in the dark about the truth."

"Before my grandfather passed away, he clearly said that one of our ancestors used this ax to slay a dragon …" Neptune clearly heard the man's whisper.

Gu Ding was about to leave, but Neptune stopped him. "Gu Ding, wait. Pick up that ax and let me scan it carefully."

Although Gu Ding was a little puzzled, he turned around and said to the man, "Can I take a look?"

"You want to buy it?" The man stopped muttering and looked at Gu Ding in surprise. Gu Ding had clearly not been interested earlier.

"I'm just taking a look." Gu Ding felt that the result would be the same if Neptune scanned it again. However, he still picked up the ax according to Neptune's instructions. It was heavy in his hand, but other than that, he did not feel anything else.

He studied the axe in his hand carefully. The axe handle was made of black metal, and the body of the axe was mottled with rust. The rust made Gu Ding frown slightly.

Noticing Gu Ding's expression, the man quickly explained, "These rust stains can't be removed. I've used a lot of cleaners, but none of them worked."

A moment later, Gu Ding heard Neptune's anxious voice. "Gu Ding, buy it! I made a mistake. This is definitely something good! "

Without batting an eyelid, Gu Ding reached out and caressed the few spots of rust. No rust fell off. "How much do you want for this axe?"

"Ten billion Universe Credits!" Gu Ding was completely speechless when the man quoted the price.

When he heard ten billion, he thought that the man was going to ask for ten billion Star Credits. He did not expect the man to ask for ten billion Universe Credits. However, looking at the man's expression, it did not seem like he was joking at all. What surprised Gu Ding was that Neptune remained silent when he heard the price.

"You're quoting this price because you don't want to sell it at all, right?" Gu Ding squinted at the man.

"It's not that I want to quote this price. Before my grandfather died, he said that if one day I lose all my fortune and can't live without selling this axe, I'll have to sell it for at least ten billion Universe Credits. For this matter, he made me sign a curse-type spirit contract. If the price is lower than ten billion Universe Credits, I'll be cursed and have 100 years of bad luck … "

Hearing this, Gu Ding chose to remain silent. He waited for Neptune's reply.

"This item is worth more than the Witch Tribe staff in your hand. Ten billion Universe Credits is considered a bargain." After a long silence, Neptune's reply surprised Gu Ding. "What he said about the curse should be true. I just scanned his body, and there are indeed traces of the curse. This kind of special curse that brings bad luck to people does exist. "

"I don't think it's possible for you to sell it at this price." Gu Ding's words were actually meant for Neptune to hear. "When the auction is over, there should be fewer buyers here. If you still can't sell it by then, you can look for me."

Having said that, Gu Ding turned around and walked away. At this time, he was not in the mood to continue shopping, so he directly left the tower.

Once they were out of the tower, Gu Ding asked, "What was that ax?"

"The owner of that axe should be a deity. Unlike the Witch Tribe staff, this axe is a melee weapon and has been stained with the blood of the Dragon Tribe. The axe itself is in a sealed state, and the remaining dragon blood covered it, concealing the aura of the seal. That's why I didn't notice anything unusual about the axe before. The rust spots you see are the traces left behind by the dragon blood. "Neptune's explanation shocked Gu Ding.

"Did the Dragon Tribe really exist? I always thought they were just legendary creatures. "Gu Ding could not help but ask.

"The Dragon Tribe was one of the first intelligent races to appear in the Cosmic Sea. Not only did they have intelligence no weaker than humans, but they were also born with great strength. As long as the real Dragon Tribe reaches maturity, they will naturally have power comparable to a deity. They were the most active in ancient times and dominated almost the entire era. The entire Cosmic Sea was their world. However, in the end, they could not escape the great catastrophe of the Changing Era. The entire race was almost wiped out, and only a few survived … "

Hearing Neptune's story, Gu Ding was a little distracted. He could not imagine that such a powerful race would still be wiped out.

"The main reason I asked you to buy the axe is not because of the axe itself, but because of the dragon blood. Through the remaining blood stains, I should be able to study the characteristics of the Dragon Tribe's gene chain, which will be helpful for your future evolution. If I get enough genetic information, I might even be able to clone the Dragon Tribe. Of course, there's no way to achieve this in the short term. "

"As for that axe, when you are strong enough, you can erase the original owner's remaining will to fight and refine it again. It's obviously much more valuable than the Witch Tribe's magic staff." The Sea Emperor had everything planned out.

However, Gu Ding thought of a practical problem. "I think if the curse that guy said is true, it's unlikely that he'll lower the price. So, the biggest problem now is that we don't have enough money."

Hearing Gu Ding's question, Neptune was silent for a moment before suggesting his idea. "Why don't we sell the Witch Tribe staff this time? We have no use for it anyway."
