Mo Wuji quickly pocketed their rings and followed Lou Si.

Lou Si was extremely fast. After half a day, she led Mo Wuji into a bustling marketplace. Hanging outside the marketplace were large characters that read, "Sky Beyond the Sky Corridor Marketplace."

Before entering the marketplace, Lou Si took out a black scarf to cover her face, seemingly aware of her beauty's potential to cause trouble.

Mo Wuji looked at the people coming and going in the marketplace, and was surprised to find that there were demon clans, human clans, magic clans, and some races he didn't recognize.

Before he could ask Lou Si, two cultivators who had been arguing suddenly started fighting. The surrounding people quickly moved aside, and the human cultivator was soon killed. The demon cultivator grabbed the human cultivator's ring and quickly fled.

No one stood up to speak, and no one cared throughout the whole process.

"Lou Si, didn't you say I couldn't come to the Sky Beyond the Sky Corridor? What do you mean by bringing me here? Why is this a marketplace, and why are all kinds of people here?" Mo Wuji asked warily.

Lou Si walked into the marketplace nonchalantly and said in a low voice, "I said you can't go to the human or demon clan areas. This is the Sky Beyond the Sky Corridor Marketplace, and any race can come here at any time. Everyone comes here for one purpose: to trade. You saw those two fighting just now, right? That's because they didn't reach an agreement on the trade."

"You can just kill people here if you don't reach an agreement?" Mo Wuji was taken aback.

Lou Si sneered, "This is a place where the strong prey on the weak, where the strong are respected. However, situations like killing people today are rare. Most people will flee if they can't win. Even if a situation occurs where an opponent is killed, it usually happens between different races."

"If that's the case, who would dare to trade here?" Mo Wuji was even more puzzled.

Lou Si said calmly, "Doing business in the Sky Beyond the Sky Marketplace requires reputation. For example, if you engage in forced buying or selling more than three times, you won't be allowed to enter the marketplace. There's also a marketplace monitoring screen that shows the people who have engaged in forced buying or selling here. Many people check your reputation before trading. Generally, people will go to fixed stalls or commercial buildings to trade. It's easiest to run into problems with casual roadside transactions like the one you saw earlier.

Once a problem arises, the survivor or the person who stays should go to the marketplace's transaction management office to explain what happened. If they don't explain and run away like that demon cultivator, they will basically never enter the marketplace again, and they won't be allowed to enter."

Mo Wuji breathed a sigh of relief and said, "Since I can't go to the human or demon territories, I can stay here, right?"

Lou Si said indifferently, "It's useless. This is a marketplace, and you'll be asked to leave after staying here for more than three days, unless you have fixed property here. That is, you have a fixed commercial building or stall here. Ordinary people can't afford to buy fixed commercial buildings or stalls here. Even if they can afford to buy them, they can't hold onto them. You might say you can come back in three days. Are you just going to keep coming in and out like that? Won't you cultivate? If you don't cultivate, the Sky Beyond the Sky Corridor wouldn't be so famous."

"What do you mean by the last sentence?" Mo Wuji asked, puzzled.

Lou Si explained, "The reason the Sky Beyond the Sky Corridor is famous is that it can produce something called Qing Jing fragments. This substance contains powerful Heavenly Dao rhymes. Cultivating with it is much more effective than even the best Immortal Crystals. So, staying in the Sky Beyond the Sky Corridor, as long as you can survive, your cultivation will increase rapidly."

Mo Wuji was about to ask what Qing Jing was when he saw a man trading with a stall owner. The item the man took out to trade was actually a Hundred-Veined Leafless Fruit.

The Hundred-Veined Leafless Fruit was an eighth-grade Immortal Spirit Fruit, and a rare one at that. In the Immortal Realm, such fruits usually only appeared at auctions, but now it was casually appearing on a street stall.

Mo Wuji stopped. He heard the man with the Hundred-Veined Leafless Fruit wanting to trade for an Immortal Jin Pill. He had Immortal Jin Pills. It was a healing pill, but its effect was much worse than the Qing Pu Pill he had just given Lou Si. It was only a fifth-grade healing Immortal Pill. Not to mention one, even a bottle couldn't be exchanged for a Hundred-Veined Leafless Fruit.

The Hundred-Veined Leafless Fruit was a rare eighth-grade Immortal Spirit Fruit that could be used to refine the Immortal Vein Nirvana Pill. In the Immortal Realm, the Immortal Vein Nirvana Pill could even be said to be the best pill for repairing spiritual meridians. Its value was completely incomparable to the fifth-grade Immortal Jin Pill.

"At most, I can give you two Tranquil Void Pills. It's still a little short of exchanging for an Immortal Jin Pill," the stall owner said nonchalantly.

Mo Wuji almost spat out his drink. Someone was saying that an eighth-grade Immortal Spirit Herb, the Hundred-Veined Leafless Fruit, could only be exchanged for two fourth-grade healing Immortal Pills, the Tranquil Void Pill, at most. If someone dared to say that in front of him, he would kick them away.

What puzzled Mo Wuji was that the guy with the Hundred-Veined Leafless Fruit was still considering, as if two Tranquil Void Pills weren't out of the question.

"Wait..." Mo Wuji was about to step forward to speak. He had Immortal Jin Pills. Since the stall owner wouldn't trade, he could use an Immortal Jin Pill to exchange for the Hundred-Veined Leafless Fruit. Only a fool wouldn't do something that was a guaranteed profit.

"Let's go." Before Mo Wuji could go over to trade, Lou Si pulled Mo Wuji away quickly.

Although Mo Wuji was puzzled, he didn't say much. Lou Si had been here longer than him and understood the various situations better.

After reaching a deserted corner, Lou Si asked in a low voice, "Did you want to trade for his Hundred-Veined Leafless Fruit?"

"Yes, what's wrong?" Mo Wuji asked, puzzled.

Lou Si sighed and said, "If you really called that person out to trade, you would be dead. First, you would offend that stall owner. Not many people who can set up a stall here are simple. Second, if others knew you had Immortal Jin Pills, with your strength, there would probably be a lot of people here who would rather not come to the marketplace and just rob you of your belongings. Also, the Qing Pu Pill you gave me earlier is priceless. There aren't many of them in the entire Sky Beyond the Sky Corridor. So you must not reveal it. Once it's revealed, you'll only have one fate: death."

"What do you mean?" Mo Wuji felt that the Sky Beyond the Sky Corridor was becoming more and more strange.

Lou Si explained, "Here, there's no shortage of Qing Jing, no shortage of various rare ores, and no shortage of various rare Immortal Spirit Herbs. What's most lacking are weapon refiners and pill refiners. Plus, there's almost always a great battle here every so often, so various healing pills and magical treasures are the most scarce. Slightly famous pill refiners will mysteriously disappear."

"Where do those top-grade rare ores and Immortal Spirit Herbs come from?" Mo Wuji quickly asked.

"From the Universe Wall," Lou Si replied calmly. After speaking, she continued without waiting for Mo Wuji to ask again, "The Universe Wall is above the void of the battlefield you saw earlier. Every two to three years, an endless passage will appear in that void battlefield. The passage is unknown, but all that's known is that it rolls in endless shattered Qing Jing, as well as various top-grade Immortal Spirit Herbs, advanced weapon refining materials, and even top-grade magical treasures, etc."

"You're saying those top-grade Immortal Spirit Herbs and various materials come from that Universe Wall?" Mo Wuji asked in surprise.

"That's right." Lou Si nodded. "Every time the Universe Wall opens, the stone walls inside are covered with countless top-grade Immortal Spirit Herbs and shattered Qing Jing. At this time, regardless of their race, cultivators rush into the Universe Wall to snatch these Immortal Spirit Herbs and various treasures."

Mo Wuji fell silent. After a long while, he asked, "Does anyone know what's on the other side of the Universe Wall passage?"

"No one can pass through it. All that's known is that the passage will close after a certain amount of time. Everyone inside will be rolled out and dropped onto the Gobi Wasteland battlefield. That Gobi Wasteland battlefield also came about in this way. Every time the Universe Wall ends, a crazy battle will break out. Both sides will fight over the gains in the Universe Wall..."

Mo Wuji interrupted Lou Si again and asked, "The battle I saw earlier, and your injuries, were they because the Universe Wall appeared and everyone snatched Immortal Spirit Herbs and other treasures?"

"No." Lou Si shook her head. "Because the Universe Wall sometimes appears once a year, and sometimes once every two or three years. Later, when the Universe Wall didn't appear, the two sides would launch battles to snatch resources from each other. What you saw earlier was a battle caused by snatching resources."

Seeing that Mo Wuji didn't seem to understand very well, Lou Si explained further, "After the Universe Wall opens, no matter who you are, no matter how much you snatch from the Universe Wall, as long as you leave the battlefield alive, that thing belongs to you. However, you need to pay a small portion to the area where you live, as a fee. Each war is a time for both sides to plunder each other. The spoils of war need to be divided into a portion for their respective areas. In fact, many Immortal Spirit Herbs and ores are very precious. In fact, what's truly precious in the Sky Beyond the Sky Corridor is Qing Jing."

Mo Wuji understood this time. In short, these wars were a kind of consumption battle launched when the upper levels lacked cultivation resources.

Hearing Qing Jing for the second time, Mo Wuji suddenly thought of the driving crystal stones used by Da Huang. Weren't those also cyan crystal stones? Could that be Qing Jing? Thinking of this, Mo Wuji quickly grabbed a ring, and his spiritual will directly tore open the restriction and swept inside.

When one pale cyan crystal stone after another appeared in Mo Wuji's spiritual will, Mo Wuji was overjoyed. This was exactly the crystal stone he needed. This kind of thing was not only a crystal stone for Da Huang, but it was also extremely beneficial to his cultivation. Don't think that his cultivation speed in the Immortal Realm was not fast even with Immortal Crystals. If he had this kind of crystal stone, he was confident that he could cross the Immortal King level at the fastest speed.

The Sky Beyond the Sky Corridor was really a good place. After coming here, Mo Wuji felt that this place was not bad for the first time.

(That's all for today, good night friends!)
