The world is vast and mysterious. In both Cultivation Techniques and Martial Techniques, the Heaven Rank is the highest, with only the Divine Level above it.

The value of a Cultivation Technique surpasses that of a Martial Technique because it is the very foundation of Martial Arts. A person can only practice a single Cultivation Technique, whereas they can learn many Martial Techniques.

The value of a Heaven Rank Cultivation Technique is immeasurable. It can give rise to a powerful faction of martial artists, and such treasures are usually kept secret by the major powers. They rarely circulate in the outside world, let alone get put up for auction.

"It’s actually the Five-Colored Golden Core Technique! It’s said that this technique is extremely difficult to cultivate and requires the right innate talent. Throughout history, those who have successfully cultivated it are few and far between!"

"However, the power of this technique is immense. Every cultivator who succeeds is considered a prodigy, making it a powerful Cultivation Technique!"

The old man’s announcement immediately sparked a wave of discussion. Clearly, the technique was well-known, and many had heard of it.

"The Five-Colored Golden Core Technique, with a starting bid of ten thousand!"

At an auction of this caliber, there was no need to hype up the atmosphere. Everyone knew what they wanted, so the old man directly announced the starting price and began the bidding.

This auction was of a high standard, with all bids in Supreme Grade Spirit Stones. Ten thousand Supreme Grade Spirit Stones were equivalent to ten billion Low Grade Spirit Stones.

To put it into perspective, the sale of all Su Han’s recent spoils had only amounted to thirty thousand Supreme Grade Spirit Stones. But this was, after all, a Heaven Rank Cultivation Technique; despite the difficulty of its cultivation, it was worth the price.

"Eleven thousand!" a Supreme Realm martial artist called out the price through clenched teeth. This was his entire fortune, all risked for a chance at this Heaven Rank Cultivation Technique. If he succeeded in cultivating it, the returns would far surpass this cost.

It took a long time before a second Supreme Realm martial artist made a bid, and even then, he hesitated. Clearly, such a high price was a heavy burden. "Twelve thousand!"

"I bid fifteen thousand. I’ll buy it to have a look; perhaps it will offer some insights for my own cultivation."

Gold Ingot made his bid. Although he was here to kill Su Han, he was also attending the auction. If a suitable treasure appeared, he would bid on it.

While Gold Ingot’s strength couldn’t compare to the established powerhouses, his status was noble and his fortune vast. He was adorned with treasures, any one of which was worth a fortune, so he called out a bid of fifteen thousand with ease.

Once Gold Ingot spoke, the two previous Supreme bidders fell silent. It wasn’t that they feared Gold Ingot, but that their fortunes were limited, and they simply couldn’t afford it.

However, others continued to bid. But with his deep pockets, Gold Ingot raised the price several more times, ultimately purchasing the Five-Colored Golden Core Technique for the high price of twenty thousand!

Su Han witnessed the battle of money firsthand, his gaze sharp and bright as he looked toward Gold Ingot. So wealthy! He’s willing to spend twenty thousand Supreme Grade Spirit Stones on a Heaven Rank Cultivation Technique, so his fortune must be immense. If I could get his Storage Ring, I might become rich overnight! At that moment, Su Han actually hoped Gold Ingot would make a move on him, which would give him the chance to kill the man and take his treasures. In this world, one can never truly know who is the hunter and who is the prey.

The successful sale of the Five-Colored Golden Core Technique was a promising start to the auction. Soon, the second item was presented—a Semi-Holy Artifact of mediocre value.

Generally, an auction places the best treasures as the first and last items—the first to open with a bang, and the last as the showstopper. The items in between tend to be of lesser value.

Nevertheless, even if they were not as valuable as the Five-Colored Golden Core Technique, the other items were still incredibly valuable, with none having a starting bid below three thousand Supreme Grade Spirit Stones.

Su Han did not make a move, choosing to observe quietly. He had a limited number of Spirit Stones. Sun Gold was a Holy Level metal, making it highly valuable and certain to be coveted by many. He didn’t want to find himself unable to compete when it finally appeared.

"Next is the fifty-fourth auction item!"

A charred hand bone, resting on a tray, was brought out. The bone was incomplete, appearing to be only half of the original. However, the fractured surface glinted with mysterious spots of light, crystalline and translucent, making it look quite extraordinary.

"This is a fragment of a hand bone, suspected to be from a demonic entity. Though it is ancient, it still retains a noticeable sheen and energy. Perhaps one could use it to uncover the secrets of demons. Such an item is a rare find! The starting bid is three thousand!"

The old man introduced the item, but everyone in attendance was an astute individual and would not be swayed by his hype. While the hand bone was undoubtedly unusual, there was no guarantee it was from a demon. Furthermore, past cases had proven that a peculiar fracture did not necessarily mean the interior was equally extraordinary.

Most importantly, everyone present was of the Human Race. Even those who practiced Demonic Techniques were vastly different from true demons. Taking this hand bone back would offer little more than research material, making it of little practical use. Therefore, interest in the bone was lackluster, and few placed bids.

"Get it!"

Inside the private box, Su Han was startled. The Great Majestic Demon King had initiated contact with him through the Black Blade. Su Han immediately understood that this hand bone was far from ordinary. After all, the Great Majestic Demon King was an expert of the Divine Demonic Level. Anything that caught his eye could not be a mundane item.

Su Han didn’t rush to bid, instead waiting for an opportunity while asking about the hand bone’s origins. "What is it?"

"If I am not mistaken, this should be the hand bone of a Demon God," the Great Majestic Demon King explained openly. "Although much of its Magic Power has dissipated, what remains is the power of a Demon God. If I can refine it, I can break half of my seal!"

Previously, the Great Majestic Demon King had mentioned that breaking the first seal would require the flesh and blood of a Saint or ten Supremes. Now, if he could obtain this Demon God’s hand bone, he could accelerate the process significantly. The amount of flesh and blood required would be greatly reduced.

Su Han nodded in understanding. Meanwhile, the bidding below had only reached four thousand five hundred. Very few people were willing to buy such an item for mere research.

"Five thousand!" Su Han called out. His voice, altered by the private box’s formations, was unrecognizable.

This was the first time someone from one of the ten major private boxes had placed a bid, drawing many gazes. Unfortunately, due to the shielding Formation, no one could see Su Han.

Gold Ingot also looked over, a curious glint in his eyes, but he said nothing more and placed no bid.

In the end, Su Han successfully acquired the Demon God’s hand bone for five thousand. Saint You Heng even granted him a special privilege, having the hand bone delivered to his box before the auction had concluded.

"That’s right, this is indeed the hand bone of a Demon God! If I refine it, my strength will recover even further!" the Great Majestic Demon King confirmed, his tone brimming with excitement.

Su Han didn’t hesitate, handing the Demon God’s hand bone over to the Great Majestic Demon King to refine. Meanwhile, he continued to follow the auction.

None of the subsequent items were worth a bid from Su Han. One by one, the lots found new owners amidst the rising and falling calls of the bidders.

"The seventieth auction item, Sun Gold!"

Finally, the Sun Gold that Su Han had been waiting for had appeared.
