Back at the Luoxia Inn, Leng Feng carefully studied the selection terrain that Duan Daguang said, and this selection was more beneficial to him, so he didn't worry too much.

There are still three days before the official start of the selection, and in these three days, Xuanyuan Gate is still recruiting students in Qinglong Square, but Leng Feng has nothing to do, so he simply walked around in Tianyong City.

In addition to the NPCs fixed in the system, there are many aborigines in Tianyun City, their level is not low, and there are stalls in the big and small markets, selling some medicinal materials and materials.

"Exercise cheats, exercises below level 20, heart method, body method, formation, all kinds of invincible exercises, the owner is invincible in the world, fifty spirit stones are on sale....."

"Herbs, materials, all kinds of rare materials, magic cores, everything, take a look."

Feihong Lane, the largest bazaar in Tianyong City, where there are all kinds of elixir materials, weapons and exercises, etc., are even more dazzling, although there are many samples, but it is difficult to have real good things.

Leng Feng wandered around the alley, looking at all kinds of ancient weapon fragments, and some broken ancient books, these are said to be ancient things, either imitations, or useless, if you want to get valuable treasures, it is almost a needle in a haystack.

"Hey, this guest officer, I see that your Yin Tang is red, and you will definitely be able to find a good treasure today!"

A chubby middle-aged vendor grabbed the cold wind, looked at the cold wind with a thief in his eyes, and in his hand was a black broken knife, which looked like it had been some years.

"Oh? Thank you for your good words, I still have something to do, so I'll go first."

Leng Feng laughed and glanced at the black ancient knife in the fat vendor's hand, although it was full of vicissitudes, it did not have a trace of spiritual power fluctuations, it was obviously a low-level weapon.

"Alas, this little brother, it's not too late to go again, I still have a lot of them here."

Seeing that the cold wind was about to leave, the fat meat on the fat vendor's body trembled, and hurriedly pulled the cold wind to the stall, pointing to all kinds of antique weapons on the stall.

"Quick! Buy the black ancient knife in his hand, there is a treasure in it! ”

Xiaomi shouted excitedly, staring at the black ancient knife with his eyes, he felt a simple aura coming from the knife, he couldn't tell what it was, but it was definitely an extraordinary thing.

"Boss, what is the use of your broken knife, if you really use this, it is better to be empty-handed"

Leng Feng took the fat merchant's black ancient knife, his mouth was disdainful, but his hand grasped the knife very tightly, and there was a bit of cunning hidden in the deepest part of his eyes.

"This little brother, although this ancient knife is not powerful, but it has good feng shui, often carried on the body, prosperous wealth, you look at the lines of the knife, this is the black dragon in the sky, it must be to help you soar!"

The fat trader squinted his eyes with a smile, blew his beard and pointed at the black ancient knife, startled, he had been walking the rivers and lakes for many years, and he had become half a great immortal.

"Okay, okay, I want this fragment of the Dragon Flame Formation, by the way, let's change this ancient knife to feng shui"

Leng Feng picked up a yellowed formation scroll from the stall, although he had a magnetic Xuan Array Armor, it was good to read one more book for reference.

"Well, this little brother, your vision is really not ordinarily good, although this Longyan Formation is a fragment, it is said to be a famous work created by the Formation Grandmaster Longyan Ancestor eight hundred years ago, and it is comparable to a fourth-level formation when it is perfect!"

"Even if I have a fate with you, this Dragon Flame Formation Fragment will collect ten spirit stones from you, and the ancient knife will be given to you."

The fat merchant first boasted about it, and then pretended to be generous to give the ancient knife to Leng Feng, and still tugged at Leng Feng's sleeve in his hand, for fear that he would leave.

"How about you take a look at this spirit stone?"

Leng Feng put away the black ancient knife and the fragment of the Dragon Flame Formation, and a blood-red spirit stone appeared in his hand, this is a special spirit stone in the Blood Remnant Realm, and the spiritual power inside is extremely pure, if it can be absorbed regularly, it will definitely be of great benefit to cultivation, but I don't know if it can be used outside.

Source ..... Source Stone?! ”

The fat vendor's small eyes, which were originally thieves, were full of eyes at this time, and he took the blood-colored spirit stone from Leng Feng's hand like a heavy treasure.

"Source Stone? How many spirit stones can this source stone be worth? ”

Leng Feng was a little puzzled and asked Xiaomi.

"Alas, there are so many treasures, I forgot to tell you"

"This source stone is the first batch of spirit stones that will be produced in a space after a long period of brewing, the aura is extremely pure, and it also contains the origin of heaven and earth, which is not comparable to the spirit stone at all."

"One source stone can be exchanged for five hundred spirit stones, this is before, and I don't know what the market is now."

Xiaomi looked helplessly at the mountains of source stones in the blood remnant realm, thinking that those old stubborns were really willing to pay for it.

"Yes, this little brother, take whatever you want at this stall, you're welcome!"

The fat vendor looked at the source stone with a smile, and didn't look at the stall behind him.

Leng Feng's face darkened, slightly embarrassed, and he was probably the only one who could use the source stone as a spirit stone.

Leaving from Feihong Lane, Leng Feng went back to Luoxia Inn directly, there is still one day before the Xuanyuan Gate selection, and he must adjust his state, if he can be a personal disciple, he is undoubtedly one step closer to seeing Ruoyun.

Leng Feng arranged a few simple detection spirit arrays in the room as usual, and the black ancient knife appeared in his hand as soon as he stretched out his right hand, except for the fact that this appearance was really a bit of a black dragon, the other cold wind really didn't feel anything unusual.

"What I sensed should be inside this blade, I'll open it and try it."

As soon as the light of the Dharma bracelet flashed, millet appeared on the opposite side of the cold wind, still a fleshy child, making people want to play with it when they went up, and he was always ravaged by the cold wind A large part of this is the reason.

With the continuous change of millet handprints, the ancient knife continued to fall off, getting smaller and smaller like a cocoon, and gradually only a piece of black ancient token remained.

"Black Dragon Order!"

Leng Feng took the black token and looked at it carefully, the quaint aura came out spontaneously, and he looked at it as if there was a black dragon rushing straight into his mind.

"I don't feel like it has any other effect now, it should be the key to a mysterious place, put it away first, maybe it will be of great use later!"

Xiaomi also carefully looked at the Black Dragon Order at this time, and did not dare to draw conclusions easily.

Let Xiaomi bring the Black Dragon Order back to the Dharma space, Leng Feng took out the fragment of the Dragon Flame Formation in his hand, this formation is composed of three parts, illusion, dilemma, and killing, the three parts depend on each other, and the combination is infinitely powerful.

Leng Feng is now getting the illusion chapter, and a single part can only exert the power of the second-level spirit array, but it is just very useful for Leng Feng!
