Looking around the cave, searching every inch, he moved with extreme caution, not daring to make any noise, in case he attracted the fire elementals from the depths of the cave. That would be troublesome.

Gradually reaching the corner, taking advantage of the dim light, Nie Yan finally found a dilapidated box.

The box was made of wood, long eroded by the wind, broken and battered, looking extremely inconspicuous. It couldn't compare to the exquisite silver treasure chests and gold treasure chests at all. The only thing that was noticeable was the fire element immunity rune on the wooden box.

It was like an ancient character, printed on the surface of the box, simple and unadorned. However, such a simple character could completely isolate the fire element, ensuring its integrity.

"This should be the box!" Nie Yan opened the box, rummaged inside, and took out a ring. He took a look.

Crawler's Ring: Unidentified.

This, along with the Weaver's Ring, was known as one of the two essential rings for high-end players, the Crawler's Ring!

Nie Yan used Super Appraisal to identify the attributes of the Crawler's Ring.

Crawler's Ring (Bronze): Special Item.

Attribute Description: After using this skill, your hands become sticky, allowing you to climb vertically on rock walls and trees. Duration: ten minutes. Skill cooldown: one hour.

Weight: 1 pound.

Restriction: Usable by all factions.

The Crawler's Ring and the Weaver's Ring were both special items, both good for climbing walls, which was why Nie Yan cared so much.

Nie Yan had come specifically for it!

With it, almost no obstacle could stop Nie Yan!

Nie Yan also put on the Crawler's Ring.

Having obtained what he wanted, Nie Yan thought for a moment. Using a Return Scroll here might alarm the fire elementals in the depths of the cave. That would be terrible.

A rhythmic snore came from the depths of the cave, and waves of heat washed over him.

Nie Yan tiptoed to the entrance of the cave, used the Crawler's Ring, and a strange suction force appeared on his palms. He pressed his hands against the rock wall, and they immediately stuck to it firmly.

Nie Yan was like a spider, clinging to the rock wall, crawling quickly and easily, as if walking on flat ground.

In Nie Yan's eyes, any cliff was no longer a problem!

Climbing down the rock wall, searching for a suitable foothold, Nie Yan finally found a protruding rock on the wall, stood on it, and was finally able to free both hands to use the Return Scroll.

"Below seems to be a level 20+ monster spawn area, with quite a few elite monsters!" Nie Yan looked at the bottom of the rock wall, thought of the Thunderfire Scroll in his backpack, and a sense of excitement rose in his heart.

With his current attack, killing level 20+ monsters was too difficult. He couldn't do it, but Thunderfire could!

This intermediate rare scroll could kill level 20+ monsters!

30 Intelligence, I have to find some equipment to increase Intelligence! Nie Yan thought, and began to read the Return Scroll. Dazzling white light shone from the scroll, and a teleportation array appeared around Nie Yan.

A flash of white light, and Nie Yan returned to Thysor Town, and then took the teleportation array back to Calore City.

Walking on the wide streets of Calore City, people were advertising everywhere: "Buying black phenol potion for twenty-five copper coins a bottle!" Obviously, no one responded. Black phenol potion was now extremely scarce. Every guild wanted it. Who would sell it?

Twenty-six copper coins!

Thirty copper coins!

Thirty-two copper coins!

The guilds were offering higher and higher prices, but still no one responded. They were dumbfounded.

Some guilds simply sent people to squat in the auction house. Occasionally, a few alchemists who could make black phenol potion would take out a few bottles and throw them into the auction house to sell, immediately causing the guilds to scramble. The most expensive bottle of black phenol potion was auctioned for fifty copper coins.

In this life, the shortage of black phenol potion came faster, more fiercely, and more terrifyingly than in his previous life, leaving the guilds at a loss.

With the price of black phenol potion being so high, the guilds' profits from descending to Sothos Valley were already very small. However, Sothos Valley had to be explored. The official website had already revealed a list of various equipment drop rates in Sothos Valley. The werewolves dropped warrior equipment, which was crucial for the development of the team. The werewolves also gave a lot of experience. It was just too difficult. Without at least ten attempts at clearing the valley, they wouldn't be able to get through Sothos Valley. How much black phenol potion would that consume?

At this time, probably only the Holy Roman Empire could descend to Sothos Valley smoothly. The Holy Roman Empire had bought so much black phenol potion from Nie Yan that it was enough for them to use for a while.

Seeing the shortage of black phenol potion in the auction house coming so fiercely, and the price being driven up so quickly, Nie Yan was quite surprised. He thought that the players would have some stock on hand, and the guilds would send people to collect raw materials and recipes to sustain them for a while. He didn't expect that it had only just begun, and the price of black phenol potion had been driven up so much.

He also understood that this price was already the limit. If it were any higher, these guilds would lose money every time they descended to Sothos Valley. Who would do such a thing?

It was time to sell the black phenol potion!

Nie Yan put ten bottles of black phenol potion in the auction house. These black phenol potions were immediately snapped up, and the price rose steadily, only stopping at around fifty copper coins. All ten bottles were sold, and the profit was good. Nie Yan put another ten bottles of black phenol potion in the auction house. Unsurprisingly, they were still snapped up.

Nie Yan continued to sell in small batches, continuously.

The guild leaders all gathered at the auction house when they heard the news that black phenol potion was being sold.

Nie Yan sat in the back row of the auction house seats, glanced at the entire auction house, and found several faces that were very familiar to him. They were all heads of the guilds. The shortage of black phenol potion was obviously giving them a headache.

Two players sitting not far from Nie Yan discussed in a low voice.

"Now black phenol potion has become a topic of concern throughout the server. Who do you think has so much black phenol potion? Ten bottles at a time. He doesn't seem to be planning to sell all the black phenol potion at once. This guy has good tactics. Selling it all at once definitely wouldn't earn much money. Selling it slowly like this, dangling the big guilds, is the only way to drive up the price."

"Fifty copper coins for a bottle of black phenol potion, what a dark price! He's going to make a fortune. But he hid his name when he auctioned the black phenol potion, so no one knows what he's called."

Nie Yan smiled slightly when he heard this whisper. It was time to make a big profit!

Because there was really too much black phenol potion in the warehouse, if he didn't sell it off in batches, by the time the guild members had collected a large amount of black phenol potion, the black phenol potion in Nie Yan's hands might rot.

Nie Yan just sat in the auction house, taking it easy, temporarily not going to grind monsters to level up, and feeling relatively relaxed and carefree.

Under the huge market demand, Nie Yan's black phenol potion was particularly popular. The guilds that had purchased black phenol potion had already restarted the exploration of Sothos Valley. The guilds that had not purchased black phenol potion were also anxious. Even if they were being blackmailed, the exploration of Sothos Valley had to continue, right?

Although there were small batches of black phenol potion for sale on the market, many guilds did not have alchemists who could make black phenol potion, fearing that the black phenol potion would run out, they had to buy more for backup. Under the huge demand, the price of black phenol potion remained high.

The market boom made Nie Yan's wealth roll in, and the money in his backpack doubled and doubled.

In total, he sold more than five hundred bottles of black phenol potion. After calculating, Nie Yan actually earned a full sixteen gold coins. In the next six or seven days, the profits that those dozens of guilds obtained from descending to Sothos Valley basically fell into Nie Yan's pocket. In the early stages, such a huge amount of money was simply amazing. Moreover, Nie Yan had more than three hundred bottles of black phenol potion, a large amount of raw materials, and two hundred and twenty black phenol potion recipes. The recipes were the main thing. The selling price of a black phenol potion recipe had already been hyped up to twenty silver coins, and there was still an upward trend. Nie Yan was not in a hurry to sell them off. He would wait until the black phenol potion and raw materials were all sold before talking about it.

Having sixteen gold coins out of thin air, Nie Yan immediately became rich. Even some of the big guilds only had three or four gold coins in liquid funds at most. In the early stages, players needed money, and ordinary players didn't even have enough money for themselves, so why would they donate money to the guild? Having not joined the guild for very long, they didn't have a strong sense of belonging to the guild, so it was very difficult for the guild leaders to raise funds. They could only collect funds from the direct troops, but if they scraped too hard, not only would their subordinates complain, but it would also affect their development.

With money, it was not wise to let it rot in his hands. He had to turn it into more money. Nie Yan thought of land!

At this time, the server had already started selling land in Calore City. Some of the houses along the street were to be demolished to build player shops. The land in important locations on various streets was being sold. However, the Calore City Governor Trus, who was responsible for selling the land, had a deserted courtyard. The price of a piece of land was at least one or two gold coins. Some of the better located shops were even worth dozens of gold coins. Even the big guilds could not take out so much liquid funds at once.

The players mostly disliked the location of those pieces of land worth one or two gold coins and were unwilling to buy them. They couldn't afford the better located and more popular land, so they could only give up.

However, in the future, as the liquid funds of the major guilds increased and the game transactions became more prosperous, the land would definitely be snapped up by the major guilds! This was the trend of the future!

Every guild was constantly accumulating wealth, preparing to expand.

If he bought land, whether he opened his own shop or built a shop to rent to others to collect rent, it would be a good plan.

With so much money in his hand, keeping one or two gold coins would be enough for his daily expenses. Buying the remaining money into land would not only preserve its value, but also increase its value. Why not do it?

Virtual real estate, like real estate in the real world, also had value!
