"Your Alliance Leader's insight is truly remarkable," Han Li said with a raised eyebrow, nodding.

As he spoke, his divine sense had already entered the jade slip, and his expression shifted slightly.

The jade slip listed over ten thousand auction items, along with their starting prices, etc., all very clear and easy to understand, making it clear at a glance.

However, the order of the auctions was not specified, which was understandable, as knowing the auction schedule too clearly would diminish the excitement.

With Han Li's current memory capacity, he quickly read through all the auction items, memorized them, and had a general idea of what he wanted to bid on.

"May I ask where the two seniors are from? What treasures are you looking to purchase this time? Are you perhaps preparing to advance to the Grand Luo realm?" Lan Mei asked again.

"We are both rogue cultivators, with no fixed abode. We have no specific items in mind for this Sun and Moon Pavilion auction; we'll just take a look first," Han Li said with a chuckle.

"I see. Our Sun and Moon Pavilion attaches great importance to this auction, and we have prepared many treasures, immortal artifacts, elixirs, materials, cultivation methods, and so on. The two seniors are welcome to browse freely and participate in the bidding if you see anything you like." Lan Mei did not press further and smiled charmingly.

Han Li nodded and inquired about some matters related to the auction. Lan Mei was well-behaved and eloquent, answering each question in detail, which pleased Han Li greatly.

Seeing Han Li chatting and laughing with Lan Mei, Ti Hun couldn't help but pout slightly, sulking and ignoring them, closing her eyes to examine the jade slip.

Soon, Lan Mei led Han Li and Ti Hun to a private room.

The room was not large, only about two or three zhang in size, and contained a long bench and a white stone table. The table was set with spiritual tea, immortal fruits, and other extraordinary items.

Although the arrangement was simple, it gave a sense of cleanliness and tidiness. The air was filled with a faint fragrance, from some unknown incense, that calmed the mind.

The room was enclosed on all sides, with a window made of transparent material on the front, providing a view of a huge square, about twenty to thirty li in size. The square was filled with countless seats, almost all occupied, with people waiting for the auction to begin.

The VIP seats, like Han Li's, were arranged in a fan shape, suspended in the air above the square.

"Alright, you don't need to attend to us here. Go down first," Han Li said to Lan Mei, nodding, quite satisfied with the situation.

"Yes, if the two seniors need to summon me, just ring this small bell," Lan Mei replied, placing a small bronze bell on the table before retreating.

After she left, Han Li flicked his sleeves, and a layer of azure light enveloped the entire room.

"Ti Hun, why have you been so quiet?" He turned to look at Ti Hun and asked.

"Master, you were chatting so congenially with that little girl, how could I dare to interrupt?" Ti Hun opened her eyes, but did not look at Han Li, and said with a straight face.

"There's nothing congenial about it; I was just asking her about the auction," Han Li said with a wry smile.

Ti Hun's expression softened slightly upon hearing this, but she still snorted softly.

"Alright, the auction is about to begin, don't be childish. You've been looking at the jade slip for so long, have you found any treasures you like?" Han Li asked.

"I did find two immortal artifacts that I like, but their starting prices are quite high. It will probably cost a lot of immortal essence stones to acquire them," Ti Hun said, pointing out the two immortal artifacts on the jade slip to Han Li, with a hesitant expression on her face.

"These two immortal artifacts are indeed very suitable for you. As for the immortal essence stones, don't worry," Han Li said, scanning the two immortal artifacts pointed out by Ti Hun with his divine sense, along with their starting prices. His brow furrowed slightly, but then relaxed, and he said with a smile.

He had previously consumed nearly twenty million immortal essence stones to operate the Light Yin Heavenly Dipper Formation, but he still had fifty million immortal essence stones. Although these two immortal artifacts were valuable, their contained law power was relatively niche, so he estimated that there would not be many bidders, and it should not be a problem to acquire them.

He had advanced to the Grand Luo realm and could not make new breakthroughs in the short term, so he could temporarily free up these immortal essence stones for use.

"Thank you, Master!" Ti Hun said, with a look of joy on her face.

"Squeak, squeak, squeak..." At that moment, a series of calls rang in Han Li's mind. It was the Essence Flame Boy inside the Flower Branch space.

Although the calls were not coherent sentences, Han Li understood the Essence Flame Boy's meaning: it needed some fire essence to replenish its previous consumption.

"No problem," Han Li transmitted a message with his divine sense, appeasing the Essence Flame Boy.

The auction list contained many materials with rich fire essence, and they were not expensive, so he could buy some.

Xiao Bai was also shouting and clamoring in the Flower Branch space, but he did not ask Han Li to buy him any treasures, instead clamoring to come out and watch the auction.

Han Li was helpless and had to send a wisp of his divine sense deep into the Flower Branch space, projecting the scene of the auction outside.

Just then, three loud bell sounds of "clang," "clang," and "clang" rang out, and the auction officially began.

A red light flashed on the auction stage in the center of the square, and a fat old man with a wide face and large ears appeared out of thin air.

Han Li's eyes flickered slightly. This fat old man was unremarkable, but he was a powerful cultivator in the mid-Grand Luo realm. His presence as the auctioneer was enough to hold the stage.

"The Ten Thousand Treasures Festival of my Great Golden Source Immortal Domain, held once every ten thousand years, officially begins today! Welcome, fellow Daoists, for gracing my Sun and Moon Pavilion with your presence. I hope everyone can bid on their desired items and return with a full load. Well, I won't say any more unnecessary words. Let's start with the auction of the first treasure. Please take a look, everyone." The fat old man cupped his hands. Several burly men in blue vests carried a jade box onto the auction stage.

Inside the jade box was a yellow crystal stone the size of a millstone, with countless earth-yellow rays of light rotating and flashing around it. A thick and unparalleled earth law power radiated from it violently.

The gravity near the auction stage was also affected by this crystal stone, becoming thousands of times heavier. The burly men found it very difficult to lift the jade box.

"Please take a look, everyone. This Earth Sovereign Crystal comes from the Earthen Earth Immortal Domain, born in the endless depths of the earth, absorbing the essence of the earth for hundreds of millions of years. The material is extremely hard and contains an abundance of magneto-gravity law power, more than enough to refine a fourth-grade earth-attribute immortal artifact. The starting price of this treasure is five million immortal essence stones, with each bid increasing by no less than one hundred thousand," the fat old man said in a plain tone, without much praise for the treasure, but this instead gave people a more reliable feeling.

As soon as the old man's voice fell, the venue buzzed with discussion, causing a huge wave of sound, and many people showed excited expressions.

Han Li's eyes lit up when he saw the Earth Sovereign Crystal on the stage.

Although he had seen this item on the jade slip, it was still not as shocking as seeing the real thing.

The Earth Sovereign Crystal is considered to be the most top-grade earth law material, not inferior to the Heavenly Gold Drill in the gold law material, and is the most sought-after treasure in the eyes of all cultivators who practice the earth law.

Moreover, this Earth Sovereign Crystal can actually be used to refine a fourth-grade immortal artifact.

In the grade of immortal artifacts, the fourth grade is a watershed.

Although there are not many fifth-grade immortal artifacts, there are also not few. Generally, those with the power to reach the Grand Luo realm will eventually have one with some effort or capital. After all, as long as the material for refining the immortal artifact is not bad, one can slowly refine and nurture it with time, and increase the grade of the immortal artifact to the fifth level.

Han Li's Azure Bamboo Bee Cloud Swords were like this. Relying on the Azure Bamboo Bee Cloud Swords' not weak foundation, and with the help of the power of the Five Lights Thunder Sea and the refining method in the *Five Thunders Celestial Scripture*, they were completed in one fell swoop.

But the fourth-grade immortal artifact is not possible. To refine a fourth-grade immortal artifact, the requirements for material quality and refining technology are extremely harsh, even to the point of being heaven-defying. It is said that after it is refined, there is also a Treasure Tribulation.

He was not very clear about the specifics.

However, once refined, the power of the fourth-grade immortal artifact can destroy the world, far more than the fifth-grade immortal artifact can compare.

The number of fourth-grade immortal artifacts in the True Immortal Realm is extremely small, and even among the Grand Luo cultivators, only a very small number of people have them.

This Earth Sovereign Crystal can actually be used to refine a fourth-grade immortal artifact. The quality is extremely high among similar materials, and the value can be imagined.

Han Li looked at the Earth Sovereign Crystal on the stage, his eyes flashing constantly.

As expected, it was worthy of being the Ten Thousand Treasures Festival. The first auctioned item was so precious.

Although this Earth Sovereign Crystal was good, he did not need it, so he did not bid.

Although Han Li did not need it, many cultivators in the venue below wanted this treasure, and they bid enthusiastically. Many of those in the VIP seats also participated.

In the blink of an eye, it broke through the price of ten million immortal essence stones, and was finally bid on by a cultivator in the VIP seat for the high price of twelve million immortal essence stones.

"The next treasure is a Fire Dao Pill, fifth grade..." The fat old man continued to introduce the second auction item.

The Ten Thousand Treasures Festival lived up to its name, with one rare treasure after another appearing, dazzling the eyes and constantly pushing the atmosphere of the venue to one climax after another.

Although the auction prices were high, many cultivators were still willing to buy the items they needed. After all, these treasures were rare opportunities. If they missed this opportunity, they would not know when they would encounter them again.

In the blink of an eye, half a day passed, but Han Li remained seated in place, without making a move.

"The next treasure is a fifth-grade immortal artifact, called the Underworld Ghost Claw. It was refined using the claws of a Grand Luo realm Underworld Ghost Beast from the Underworld Sea Immortal Domain, combined with countless fierce souls, eighteen kinds of ghost blood, thirty-six kinds of ghost energy, and burned in the Underworld Fire for millions of years. It contains an extremely powerful Yin Ghost attribute law, with extremely strong penetration and corrosive effects." On the auction stage, the fat old man took out another treasure, which was a black claw about ten zhang in size.

This black giant claw had nine fingers, and the gaps between the fingers were full of webs. Countless black qi swirled around it, emitting bursts of powerful ghost wails, like the hand of a demon.
