The Burial Tower of Immortals buries the heavens, the earth, and all the immortals.

The final item up for auction was indeed the Spirit Source that everyone had been eagerly anticipating!

Spiritual Source is a super treasure that, once refined, can directly enhance physical strength and even cultivation level without any side effects!

This is also the ultimate purpose for many top figures who are unwilling to travel hundreds of thousands or even millions of kilometers to attend this auction.

Even many top figures refrained from bidding on items they liked at previous auctions, or at least did not bid with all their might.

The purpose is to save spirit stones and use them on bidding for spirit sources, which is the real key!

At this moment, the spiritual energy, about the size of a palm, was in liquid form and contained in a specially made transparent jade bottle.

The entire auction hall instantly entered an unprecedented climax.

Especially those top figures in the front row, their usually calm and composed faces were now filled with excitement, and their originally cloudy old eyes were now shining with excitement.

"This is the last and most precious item in this auction: the Spirit Source!"

On the auction stage, Yan Ruyu's beautiful face was also filled with excitement.

Spiritual sources are extremely rare. Not to mention in the Northern Continent, even in the entire Great Wilderness, they are absolutely priceless treasures.

She has presided over countless auctions, including several Jin Xin auctions, but this is the first time she has auctioned a spiritual source.

For her, an auctioneer, this must be a tremendous honor.

Under the expectant gazes of the crowd, Yan Ruyu continued in a detailed explanation: "This kind of spiritual source probably doesn't need much introduction from me. I'll just mention the starting bid: twenty million spirit stones!"

The moment the words were spoken, the entire audience was stunned.

Although they all understood that the value of this spiritual source was definitely more than 20 million spirit stones, the starting price was still somewhat unexpected.

This almost broke the record for the highest starting price ever recorded for any auction item in the entire Northern Continent.

"Twenty-one million spirit stones!"

"Twenty-two million spirit stones!"

"Twenty-two million five hundred thousand spirit stones!"

……

Despite the high starting price, it did not dampen the enthusiasm of the top tycoons in the front row.

"Something's not right about the spiritual energy in this special bottle."

Qin Changye frowned even more deeply, thinking to himself.

Just now, when these spiritual resources were brought onto the auction stage, he immediately activated his Devouring Heaven Immortal Body, his gaze falling upon them, which emitted only a yellow light.

Items that emit a yellow light are considered good treasures, but they are far from matching the value of the spiritual source.

This is why Qin Changye frowned the moment he saw Lingyuan.

Based on Qin Changye's experience, even a relatively low-grade spiritual source should emit a blue or even pale blue light.

Next, Qin Changye released his spiritual power to perceive the spiritual source contained in the special bottle in detail.

Soon, they discovered that the supposedly pure spiritual source was actually emanating a faint, sinister aura.

"So it was a contaminated spiritual source!"

Qin Changye suddenly realized something.

The spiritual source has extremely domineering internal properties, rejecting external impurities. The probability of it being contaminated by other impurities or evil energy is extremely low, and the difficulty is extremely high.

This is why spiritual resources are so precious, as they are treasures that can directly enhance physical strength and even cultivation level after being refined.

Because after refining, there will be no harm or backlash to the body.

However, there are also exceptions.

For example, nowadays, the value of a spiritual source that has been contaminated by evil energy will be greatly reduced.

"The evil energy that can invade the spiritual source must be extremely terrifying. With my current abilities, it's not impossible to remove it, but it would be time-consuming and exhausting, not worth the effort."

Qin Changye quickly made a decision.

This kind of spiritual source invaded by evil energy, after being refined, does not weaken the improvement of physical strength and cultivation, but may bring unknown damage and backlash to the body.

Moreover, the price has been driven too high, making bidding unnecessary.

"Twenty-five million spirit stones!"

"Twenty-six million spirit stones!"

"Twenty-six million eight million one hundred thousand spirit stones!"

……

The bidding continued at that moment.

The bidders were mostly emperors from the more than twenty dynasties in the Northern Continent.

Many of them hadn't made a single bid since attending the auction, conserving their energy and waiting for this moment to unleash their power.

"Thirty million spirit stones!"

Suddenly, a voice rang out, bidding millions more, coming from the back of the auction hall.

Everyone's attention was drawn to it; no one expected that there was a hidden expert in the back row of this auction.

The person bidding in the back row, just like the one who had bid for the Great Mighty Heavenly Dragon Seal earlier, was also masked and concealing his aura, clearly not wanting his identity to be revealed.

It was none other than the old Taoist priest with red eyebrows.

He traveled hundreds of thousands of kilometers for the Spirit Source, and for that he did not hesitate to auction off his favorite Great Mighty Heavenly Dragon Seal.

The Great Mighty Heavenly Dragon Seal, which had just been auctioned off for 20 million spirit stones, was delivered to him immediately after the Jin Xin Chamber of Commerce deducted a 10% handling fee, as per his request.

Including his remaining savings and the spirit stones he had robbed in the masked days, he had a total of nearly forty million spirit stones.

He was determined to obtain the Spirit Source!

After a brief silence, another bid rang out in the auction hall.

"Thirty-one million spirit stones!"

The bidder was none other than Emperor Wu, the old emperor of the Great Wu Dynasty.

He was over two hundred years old, extremely old, and nearing his end.

To continue to survive, the only option is to improve one's cultivation level, or more precisely, to improve one's cultivation level through external means.

The spiritual source before us is the best choice.

He was equally determined to win.

"Thirty-five million spirit stones!"

The old Taoist priest with red eyebrows gritted his teeth and continued to raise the price.

This drew sighs of dismay.

This price represents almost all the spirit stones that many emperors in the front row could afford.

They lack the courage to risk everything to bid for spiritual resources.

"Thirty-six million spirit stones!"

Emperor Wu continued bidding, and as he spoke, he turned to look at the red-browed old Daoist in the back row: "Fellow Daoist, spiritual resources may only enhance your physical strength and cultivation for you, but for me, they are essential for prolonging life. I am determined to obtain them, and I hope you will grant my request."

He paused for a moment, then continued, "If you can give up the bidding, I will owe you a great favor. In the future, if you ever need anything, just say the word, and I or my Great Wu Dynasty will do everything in our power."

This is giving both face and substance.

However, the old Taoist with red eyebrows replied coldly, "I'm sorry, but I am also determined to obtain the spiritual source. As for your favor, it is worthless in my eyes."

The entire audience erupted in uproar; this showed absolutely no respect whatsoever!

Emperor Wu's face quickly darkened: "You refuse a polite toast only to drink a forfeit? Do you really intend to be my enemy, to be an enemy of my Great Wu?"

As he spoke, he even released his aura, locking onto the red-browed old Taoist in the back row and directly suppressing him.
