Tang Long now had roughly guessed why Zhang He had been so good to him before. He has the identity of a preparatory disciple, and he has a waist card with great magical powers, and he doesn't have to pay for spending less than one hundred gold coins in Agni City when he uses this waist card!

One hundred gold coins is not a small amount, even if it is a big meal, it is only thirty or forty gold coins, even if you go to some places to find those very expensive women, even if it is an all-inclusive night, it will definitely not exceed thirty gold coins.

Zhang He is not a member of the Netherworld Ghost Clan, and his status in the Demon Heaven Sect is not high, so naturally he doesn't have much money, he is attentive to Tang Long, just to be able to play outside with Tang Long's waist card!

Where is Tang Long in the mood to play now?

He went out to breakfast, then returned to his room, first taking out the Transfiguration Inheritance Scroll.

"I don't know if it's hard to learn, and I don't know what herbs are needed for disguise. Tang Long thought secretly, opened the inheritance scroll, and immediately his mind was absorbed into the inheritance space in this scroll.

After half an hour, Tang Long's mind finally withdrew from the inheritance scroll.

"I really didn't expect that this was a very magical martial art, it was unbelievable!" At this time, Tang Long's eyes had already revealed a thick surprise, he didn't expect that there was such a magical martial art in this world!

This is indeed a disguise technique!

However, this disguise technique is completely different from the disguise technique that Tang Long understands, because this disguise technique does not need to use any props at all, what is needed is only the vitality and magic that Tang Long has cultivated!

This disguise technique turned out to be a martial art that only magicians can use, but the use of disguise requires the cooperation of magic power and vitality!

Tang Long learned the disguise technique, but he had some doubts about Hua Piaoling in his heart.

Hua Piaoling, the woman, recognized at a glance that the elixir he refined was something that only a magician could refine, and she could tell at a glance that the elixir was refined by a six-ring magician, and she also had this kind of disguise technique in her hand that only a magician could learn.

Hua Piaoling is so familiar with magicians, Tang Long feels that Hua Piaoling is probably also a magician.

"I don't want to do this, let's practice the disguise technique first!"

Tang Long took a deep breath, put aside his distracting thoughts, and then began to cultivate the disguise technique.

First of all, the work of unclogging the meridians is carried out.

Running the Nirvana Technique, the scorching vitality in his body slowly flowed in his meridians, and his whole body was wrapped in a red flame, but in this red flame, there was a trace of pitch black, exuding an incomparable scorching aura!

Gradually, in Tang Long's epidermis, strands of fine energy slowly filled, slowly moving under the skin like insects, opening up the extremely subtle meridians of Tang Long's epidermis slowly little by little.

This process took more than three hours!

Finally, Tang Long's preparations were completed, and all the meridians of his epidermis were completely opened by the Yuan Qi at this time.

Now next, let's start the most crucial part: disguise!

The Divine Demon Spirit was summoned, and then with the Yuan Qi, it slowly spread Tang Long's whole body, and it turned into a human shape very strangely, and then this humanoid energy body slowly merged into Tang Long's body, and became one with Tang Long!

"Change, change!"

Tang Long clasped his hands together in front of his chest, and quickly changed his handprints!

At this moment, his whole body, a stream of energy began to move around extremely strangely, and then all parts of Tang Long's body, the shape began to change, and even the various parts of his face began to change!

In less than two minutes, Tang Long really seemed to have become another person at this time!

He looked about thirty-seven or eighteen years old at this time, and he had become a little taller, but he was stronger than before, and his face had completely changed from his original appearance!

At this time, even in front of the mirror, he can't see himself at all!

"Hey, hey, hey, it's really good!"

Some sharp voices were a little muddy, coming out of Tang Long's mouth, this voice was already different from his original voice, there was already a difference between heaven and earth, he couldn't even believe that this was actually the voice he made!

It's amazing that this disguise technique can change the voice at the same time!

"While this transfiguration technique doesn't change me into anything at will, and it doesn't last long, it's pretty good enough for me to last a day, hehe, it's perfect!"

Tang Long was very satisfied with this disguise technique, because he learned the disguise technique in order to enter the Heavenly Demon Tower.

"Next, it's time to find a way to find the energy crystal. ”

Tang Long dispersed the disguise technique, and immediately returned to his original appearance, not even feeling any discomfort at all, he walked out of the room very satisfied, and then strode towards a place in Agni City!

Auction houses!

He is now considered a rich man, so the easiest place he can think of to get energy crystals is the auction house!

"If I can find enough energy crystals, I can arrange a lot of teleportation arrays, and I can even carve a teleportation array map for Mei'er to take with me, so that if there is something, I can be by her side at any time. ”

Where is the auction house in Agni City, Tang Long already knew from Zhang He yesterday.

According to the route Zhang He said yesterday, more than half an hour later, Tang Long had already appeared at the gate of a towering building, and when he looked up, he saw that on the door of this building, five magnificent characters were carved: Royal Auction House!

"Presumably, this should have been an auction house controlled by the royal family of the Dali Dynasty before. Tang Long thought secretly and strode in.

"Sir, what do you want to auction?" A warrior dressed as a waiter at the door stopped him, looking quite polite: "Our auction house, there are a total of ten auction halls, each auction hall, the auction things are different. ”

"You're trying to ask me how much of value I need, right?" Tang Long smiled faintly: "I need an energy crystal, do you know how much this thing is worth?"

"The value of this thing is very high!" The waiter hurriedly said: "The value of a single energy spar should be about four million gold coins, if you need it, you can go to the auction hall on the tenth floor, there are very expensive things in it, energy crystals, there are also them." ”

"Four million gold coins?"

Hearing this price, Tang Long immediately frowned fiercely!

Originally, he thought that he should already be a big tyrant at this time, but when he heard what the waiter said, he immediately felt that he was ten poor bastards!

Now, although he is very rich, he has scavenged a lot of gold coins from the Demon Heaven Hall in Heavenly Lion City, and there are many valuable treasures, but all of these add up, even if the money scavenged from those destroyed sects is added up, it will definitely not exceed 30 million gold coins!

This money is only enough to buy six energy crystals, not even enough to arrange a teleportation array!

Suddenly, Tang Long's heart became extremely depressed: "It seems that the idea of arranging a lot of teleportation arrays obviously won't work. Tang Long was secretly depressed, but asked the waiter curiously: "This energy spar is not very useful, why is the price so high?"

"Is the energy spar of little use?" The waiter looked at Tang Long and pouted: "So many people want to arrange a defensive enchantment, so many people need to arrange a formation, but the only way to arrange a formation is to use an energy crystal, can you say that this thing is not worth much?"

"Hehe, yes. ”

Tang Long thought about it, what this waiter said was indeed the truth, but he hadn't been in contact with anything like a defensive enchantment before, so he wasn't very clear about the usefulness of the energy crystal.

"Is there an auction of energy crystals on the tenth floor?" Tang Long asked.

"Absolutely. The waiter said, "This kind of thing, there are auctions here every day, and they are often auctioned in groups." ”

"How many are in a group?"

"Ten!"

"I'll take a look!" Tang Long heard the waiter say that there were ten energy crystals in a group, and he immediately became interested, if he could pick up a cheap group and buy a group, then he could just arrange a teleportation array!

Now, he'd love to set up a teleportation array.

The waiter pointed out a passage to Tang Long, and Tang Long walked up the passage, and soon arrived at the auction house on the tenth floor.

The auction house on the tenth floor is extremely luxuriously decorated, and all the equipment is very elegant and luxurious, and the auction hall is also very large, more than 10,000 square meters!

There were hundreds of luxurious wide chairs in the auction room, and most of them were already occupied.

On the auction table in front, an auctioneer is holding a hammer and shouting the price, and these guys below all look very gentlemanly, and when the price is raised, they just raise their hands, and then someone next to them will immediately raise a sign to help shout the price.

These signbearers are all staff of the auction house.

Tang Long found an empty seat and sat down.

He waited patiently for what he needed to appear, and he hoped for good luck and could wait for the energy hedron he needed, and the price was not high.

The things auctioned here are really extremely precious, and the value of any kind of thing is very high, and even Tang Long is here, and he even saw a treasure for the first time!

The role of the treasure weapon is much higher than that of the spirit weapon, and the price of the treasure weapon is, of course, even more terrifying, and the cheapest one is more than 10 million gold coins!

"Do you want to buy a treasure weapon for use?" Tang Long thought of his Death God Treasure Knife, although this treasure knife is a spiritual weapon, but compared to a treasure weapon, of course, it is far behind, to have a treasure weapon, this is definitely a very good thing for Tang Long, this can make his attack methods more powerful.

"Now, what is about to be auctioned is the rarest of treasures: the Spirit of the Night!"

Just as Tang Long was waiting patiently, thinking about whether it was time to buy something, on the auction table, the auctioneer called out a name, this name Tang Long had heard of for the first time.

So, Tang Long immediately walked towards the auction table.

In the audience, everyone's eyes also looked towards the auction table, and their eyes showed obvious expectations!
