Stepping into the realm of the Four Tribulations, Ye Feifei found that the system had actually turned on the farming mode in the dream realm.

"Mystery Farm?"

What exactly is the function, the system did not introduce, and the opening method did not tell him, but simply told him that there is such a function to open.

For this damn function, Ye Feifei could only grit his teeth and accept it, and also derived a lot of questions and inferences, since he wanted to farm, seeds were essential, and he needed to get some seeds in case of emergency.

After repeatedly deciding, Ye Feifei fell asleep, and in the dream world, he fished the dreams of a group of people from the Yan family, the Liu family, and other big families who fought with the Xun family, refined a lot of energy liquid, and divided a drop into a small bottle (normally, Ye Feifei couldn't catch so many dreams at one time, but he took a trick and used to integrate those dreams into one, and used a large-scale dream bait to evolve the treasure to catch a net, which led to a large-scale dream fishing event).

One drop is enough, the system says that as long as you drink one drop, you can make up for the excessive consumption of indulgence, even a strong person like the head of the Kaoru family can make up for one-third of the energy.

What Ye Feifei wants to auction is this drop of energy liquid.

There is an auction house called "Treasure Appreciation" in the center of Tianzi City, which is also the largest trading market in Tianzi City, and it is also managed by the royal family of the Great Zhou Empire, but no one dares to pay attention to them, it is a good place for trading.

In the Great Zhou Empire, the wealth of the Treasure Appreciation Auction House can also be ranked, and the reputation can naturally be guaranteed, which is also the reason why Ye Feifei decided to auction the energy liquid here.

With a different face of Xiao Martin, Ye Feifei wore a black cloak to cover his face, and quickly walked towards the huge auction house in the center of the city.

As for the cloak worn by Ye Feifei, it is the same robe as the fighting horse sold by the system, only one point, not to mention the material, that is, the breathability and durability are second to none, it is simply half sold and half given.

Covered by a cloak, Ye Feifei's appearance is not clear, unless they hold the light over, otherwise they don't want to see his true face, even if they see it, it doesn't matter, Xiao Martin's little fresh meat shape and aura can still dispel everyone's vigilance.

Eyes were glaring on both sides of the street, but no one had any idea, and he was not the only one who was hiding his face, just one glance at him and no longer paying attention.

Relieved, Ye Feifei knew that he had blinded a group of people, and they probably regarded themselves as their own kind.

It is said that the black cloak of the fighting horse is an artifact, and it is invincible as soon as it is worn, and it seems that it does live up to its name.

The effect of the energy liquid is very attractive to some family forces, especially the Yan family and the Zhang family, many people have been seriously depleted of energy recently, and as soon as the energy liquid comes out, it can naturally make people think of it at once, so his identity must not be revealed.

If the energy liquid is refined on a large scale, a group of people stuck at the bottleneck can use it to break through, which is undoubtedly a miracle medicine against the sky, even those big forces will hit his attention, so he has already thought of the reason before he comes.

Under the gaze of several strong men holding sharp weapons at the door, Ye Feifei calmly walked into the auction house, but his footsteps paused at the moment of stepping.

The system prompts that some kind of formation has been set up in the area, which seems to be used for exploration.

Spending a point to conceal the investigation, Ye Feifei easily found the treasure room in many rooms and knocked on the door gently.

"Come in!" The old voice came out.

Pushing open the door and walking in, Ye Feifei closed the door and came to the chair like applying for a job, and the old man who was in the position of the boss put down his work and looked up at him.

"Treasure appreciation?"

"Hmm." With a European and American timbre, it sounded, but it was a cold and abnormal feeling, and the hidden mask not only made him look great, but even the human voice became a voice corresponding to his appearance.

Sitting on the chair, Ye Feifei took out a three-milliliter test tube from his arms and handed it to the old man.

There was a rubber plug inserted in the test tube, and the transparent glass tube alone made the old man's eyes widen, and he thought that the old man had golden pupils or something through the liquid of the test tube.

This is the first time I have seen glass products for many years, and the old man's expression can be described as shocked.

"What is this?" The old man carefully picked up the test tube, squinted his eyes at the viscous liquid in the tube that flashed with a little yellow light, and pulled out the rubber plug and sniffed lightly.

In an instant, the original fatigue disappeared in an instant, and the person became refreshed.

The old man's eyes flickered, and his gaze became a little restrained, and he asked softly, "This is a kind of energy-restoring potion?" ”

"Hmm." Ye Feifei was a little surprised, it seemed that the old man still had two brushes.

"Excuse me... What is the name of the potion? Hearing this, the old man was sure of his thoughts, but although he knew the efficacy of the potion, he had never heard the name of the potion.

"Energy liquid, can make up for excessive energy consumption, eliminate fatigue, use it during breakthroughs can make the mind highly concentrated, and the use of the fluid realm can increase up to three percent of the energy."

"Make up for the energy!" The old man was a little moved, this is a good thing, if a fluid realm powerhouse breaks through the realm, he will already be mentally exhausted when he deals with the tribulation, if he drinks the energy liquid, when he is energetic, it will be easier to deal with the tribulation, increasing the chance of crossing the tribulation.

"It can be taken orally, or it can be diluted with water and provided for some weak people to use, without any ......side effects," said Ye Feifei and seriously introduced the use of energy liquid to the old man.

The old man thought for a while, handed the test tube to Ye Feifei, and said respectfully: "Forgive the old man for being clumsy, in Xia Zhang Zheng, he is an alchemist, I don't know if your name is ......"

The old man looked ordinary just now, but he became energetic just after smelling the energy fluid, and his temperament was completely different from the sloppy just now, a proper old drama bone.

"Is there any problem with Nicholas Shaw Martin in the next country?" Ye Feifei asked.

"No... No problem..."

"When is the auction scheduled?"

"I'll auction it later, this is your auction card..."The old man didn't get what he wanted, but he was not annoyed, and handed over a golden sign.

Holding it in his hand, Ye Feifei couldn't help but be surprised: "King Kong wood? ”

"Your Excellency has good eyesight!" The old man was a little surprised, but more respectful, the person who could recognize the best material was definitely not an ordinary person.

"If you see more, you will naturally know it, and you will be disturbed." Hugging his fists slightly, Ye Feifei didn't stay and slowly walked out of the room.

The door was shut, and Zhang Zheng frowned and thought for a while.

"Master Zhang Zheng, is the origin clear?" A secret door in the treasure room opened, and a middle-aged man walked up quickly.

"Overseas casual cultivation, the energy liquid is either extracted from a certain plant, or it is extracted from a certain animal, the yield should not be high, and it may also be obtained from a certain ruin..."Zhang Zheng shook his head, frowned, and said to himself with some doubts: "He should need something, otherwise he will definitely not take out such a spiritual liquid and sell it." ”

"Need to investigate his origins?" The middle-aged man bowed and said.

Zhang Zheng shook his head slightly, squinting at the middle-aged man: "Have you forgotten the rules of our auction house?" As long as he is not from an enemy country, we don't care about his origins, if he comes from those scattered cultivation alliances, the royal family can't afford to be guilty, can you guarantee that there is no huge organization behind him? ”

The middle-aged man was in a cold sweat, obviously frightened.

Zhang Zheng glanced at him and said lightly: "This time it should be a temptation, maybe there will be good things sent to auction in the future, you know what to do, right?" ”

"My subordinates understand..."

"Use your brain... Let's go down..."

"The subordinates retired..."The middle-aged man was sweating profusely and slowly exited the room...
