After some final haggling, Su Yuan secured that Supreme Treasure for a price of 250 billion Dao Sources. After obtaining the Dao Sources, the Lord of the Nine Nether began studying their special properties, seemingly trying to find a way to replicate them. Meanwhile, the Lord of the Nine Pure was also very interested in the Dao Sources and thus requested a private conversation with Su Yuan. He took out a peculiar stone and handed it to Su Yuan. "This is a peculiar stone I found in a secret location. I've divined it, and it seems to be extremely compatible with some kind of Dao Principle. It might be helpful for breaking through to the Dao Lord realm!" Seeing this stone, Su Yuan furrowed his brows slightly. "It does look somewhat interesting, but its value isn't high. At most, I can offer one million Dao Sources." "Deal!" A warm smile spread across the chubby face of the Lord of the Nine Pure. Su Yuan felt speechless internally. That was too high a price! One hundred Dao Sources would have been plenty. Perhaps the items from the Lord of the Nine Nether were too high-level, giving him an extra layer of 'filter' when evaluating items from a Dao Lord. However, he did feel this peculiar stone truly had something special about it. Thus, the two completed the transaction. Afterwards, both the Lord of the Nine Nether and the Lord of the Nine Pure tactfully took their leave and departed. After the two had left, Su Yuan addressed all the Great Emperors present in the hall. "For now, you may trade with me. All items you wish to sell can be remotely transmitted here through the invitation letter. If I am interested, I will give you a fair price!" As soon as his words fell, the Primordial Emperor felt as if all the other Great Emperors around him had vanished without a trace, leaving only Su Yuan before him. Su Yuan looked at him calmly and asked, "Do you wish to trade?" Without a word, the Primordial Emperor immediately connected with his true body and then transmitted all his possessions over, placing them into a storage-type Supreme Treasure. "Dao Venerable, these are all my treasures! Please take a look!" Su Yuan looked into the storage Supreme Treasure. Inside was a God Realm Sea, with countless treasures floating within it. The number of treasures reached an astronomical figure. Su Yuan's consciousness continuously roamed within it and indeed found some treasures worth acquiring. With a wave of his hand, a total of twenty-three items appeared in Su Yuan's grasp. The Primordial Emperor looked curiously at those items. He discovered they were all treasures he hadn't paid much attention to before. On the surface, they all looked very ordinary and had been gathering dust in his treasury. Yet now, the Dao Lord valued them. This showed just how extraordinary these items actually were, didn't it? Su Yuan looked at him calmly and said, "This Sovereign will list a transaction list for you. Take a look for yourself." Su Yuan listed the prices for all twenty-three items on it. The Primordial Emperor looked over. He saw the list didn't include the names of the items, only their images. The price of the first item was a staggering one hundred thousand Dao Sources, which was beyond his expectations. The total for all items combined reached a whopping 1.02 million Dao Sources! A huge sum! Before his joy could last long, Su Yuan had already waved his hand and taken the treasures away. He then took out 1.02 million Dao Sources and directly handed them to him. The Great Emperor excitedly accepted them. These were Dao Sources! He used one directly, and the feeling was wondrous. Now, obtaining so many in one go, he had made a huge profit! A short while later, the Primordial Emperor noticed the other Great Emperors had reappeared around him. Everyone's expressions were calm, but the Primordial Emperor could vaguely sense that everyone was quite happy. Clearly, they had all exchanged for Dao Sources to a greater or lesser extent. Su Yuan then spoke up, "The transactions are concluded. It's rare for you all to gather like this. You may trade or exchange ideas amongst yourselves. The Heavenly Palace will close within three days. You may leave at your leisure." After saying this, Su Yuan's figure vanished, clearly having already departed. The Primordial Emperor was momentarily stunned and looked towards the others. Someone had already taken out a stone mirror, listing the items they desired on it. To his surprise, he saw that the prices those items commanded actually included Dao Sources. Dao Sources had instantly become a currency for transactions among Great Emperors. A thought struck him, and he also began listing his own needs, immediately listing over three hundred items. At that moment, someone transmitted a voice message out of thin air, "Fellow Daoist, I have thirty Chaos Time Crystals, but I don't need anything else. I only accept payment in Dao Sources. For one Chaos Time Crystal, I want three Dao Sources!" "Are you trying to rob me?" The Primordial Emperor immediately glared at that Great Emperor. "Rob? Where can I rob? Tell me!" "The value of Dao Sources is too high. I'm only willing to offer ten Dao Sources to buy all your Chaos Time Crystals!" "Impossible!" The Primordial Emperor immediately began haggling with the other party. In the end, he bought the thirty Chaos Time Crystals for a price of forty-seven Dao Sources. Once that transaction ended, the Primordial Emperor proceeded to trade with others. With Dao Sources serving as currency, transactions among the Great Emperors became fast and smooth. Although the Great Emperors hadn't traded with each other before, using Dao Sources as currency made transactions much easier. The barter method of trading was extremely cumbersome. Three days passed in the blink of an eye. In the end, the Primordial Emperor didn't spend many Dao Sources before successfully gathering most of the treasures he hadn't been able to assemble over countless eons. The one hundred Great Emperors had previously been separated. It was rare for them to trade so freely and satisfyingly. Everyone was very pleased and departed in high spirits. At this moment, Su Yuan was studying that peculiar stone. "Would that fellow from the Nine Pure really be so kind as to trade a good item to me?" Su Yuan possessed the [Tear of Eternity] tag ability. Even though it had merged into the [Nine Stars Land], this tag ability didn't disappear;instead, it had been enhanced! Within the [Nine Stars Land], this peculiar stone could transform into a celestial body of an Eternal Star, with a grade equivalent to the Dao Lord level. This meant this item was truly a treasure of the Dao Lord tier. Although the quality was sufficient, the quantity was too small. Its benefit to Su Yuan was minuscule. Moreover, strangely enough, Su Yuan couldn't figure out the function of this peculiar stone either. Using all the Dao Principles he had comprehended had no effect whatsoever on this stone. What exactly was this? A bluish-black stone that looked like a chipped corner from a brick. Its hardness was extremely high. Even power at the Dao Lord level couldn't damage it. However, within the [Nine Stars Land], he could gather the combined power of the entire Nine Stars Land, plus the dual Status and power of a Dao Lord. He refused to believe he couldn't break this peculiar stone! "Break!" Su Yuan gave a low shout, applying force to crush that peculiar stone. The peculiar stone was finally crushed, turning into a small pile of powder. The powder gradually dissipated, turning into nothingness and slowly vanishing. But Su Yuan, who controlled the [Nine Stars Land], could sense that as the powder disappeared, an infinitesimal detail of a Dao Principle appeared within the Nine Stars Land. Through that tiny detail, he shockingly managed to deduce the origin of this peculiar stone! And the reason why he couldn't determine the Dao Principle hidden within the stone.
