Probably because the Tianhe Alliance has been famous in this airspace for a long time, on the day Zhang Tianjiu entered the city, as soon as the news of the upcoming auction came out, a large number of monks also swarmed in.

Because of the ban on Bai Ze City, the originally spacious street was suddenly overcrowded, densely packed with monks who came to participate in the auction, almost to the extent that they rubbed shoulders one after another.

Zhang Tianjiu stood in the inn room, pushed the window and looked down, and suddenly remembered the tourism Golden Week in the ancient era of the world of science and technology, which was exactly the same as the spectacular scenery in front of him.

Secretly amazed for a while, Zhang Tianjiu immediately dispelled the idea of shopping on the street for the first time in the cultivation world, and honestly sat in the room and closed his eyes to cultivate.

The time to stay in the cultivation world is not much, and it is a day to be able to cultivate one more day, and after returning to the scientific and technological civilization, without the support of the spiritual power of heaven and earth, even if he is the five elements spiritual vein, it will be in vain.

Time flies.

In the blink of an eye, it was the early morning of the third day.

Zhang Tianjiu's mind returned, slowly opened his eyes, and exhaled a long white gas.

It was still early outside, but the streets were already full of people, and the loud noise almost lifted the roof.

Zhang Tianjiu smiled bitterly, opened the door and went downstairs and walked out of the room, blending into the crowd and heading straight to the east of the city.

After walking a few steps out of the door, Zhang Tianjiu flashed into a shop selling cultivation items on the street, preparing to follow the example of other monks and buy a black cloak that could hide his face.

Thinking about it, his big bald head is too eye-catching, and in this mixed place, it is better to keep a low profile.

Although with Zhang Tianjiu's cultivation at the moment, even if he faced the Venerable with three or two punches to solve the battle, but in the meditation and cultivation last night, the few faint breaths that his divine sense sensed were at least the realm of a middle-level saint, but he had to be careful to beware.

It seems that the muddy waters of Bai Zecheng are far deeper than they seem on the surface.

Walking into the store, Zhang Tianjiu's eyes swept over, only to find that the scale of the randomly selected store was not small, and all kinds of magic weapons and pills were placed on the counter, which could be said to be dazzling and everything.

It's just that at the moment, most of the monks' minds are focused on the auction, and they basically don't care about patronizing these small street shops, and in the huge hall, except for Zhang Tianjiu, there are only a few leisurely monks in Chinese clothes who are walking around at will.

These people all had a precious long sword tied to their waists, and they looked majestic and extraordinary.

Zhang Tianjiu glanced aimlessly for a while, and was about to ask Wei Wuya if he had anything he liked, anyway, he was not short of money now, his eyes suddenly lit up, and his eyes were attracted by a stone with a whole body of turquoise.

Biyun ore!

Zhang Tianjiu was shocked, and his face showed irrepressible ecstasy.

He never dreamed that he would actually see such a large piece of Biyun Ore Rough Stone in the Xiuzhen World.

Biyun ore itself does not have too many peculiarities, but it can refine a precious stock solution called bixanthin, and bixanthin stock solution is one of the necessary materials for synthesis of high purity.

From CRT3 to CRT5, it is inseparable from the neutralization effect of the bixanthin stock solution.

It's just that the output of Biyun ore is extremely rare on the side of scientific and technological civilization, and each piece is so precious that it can't be measured by value at all.

With more than 300 years of experience ahead of the current world, Zhang Tianjiu naturally controls the production areas of several Biyun mineral deposits, but those places are located in extremely desolate and dead airspace, and are buried under the core of the earth's crust.

For a long time, Zhang Tianjiu thought that this precious ore was only stored in small quantities in the world of science and technology, and he didn't expect to see such a large piece of rough stone in Bai Zecheng today, which was simply a big luck.

"Calm...... Be sure to be calm. ”

Zhang Tianjiu took a few deep breaths, stabilized his excitement, and didn't let the expression on his face betray his true thoughts.

He still didn't know what the purpose of the blue ore was in the cultivation world, but judging from the fact that such a large piece was randomly placed in a cultivation shop, this thing should not be a precious thing in the eyes of the monk.

The most important thing at the moment is to buy this rough stone immediately, and must not let the shopkeeper see the abnormality, and give him a chance to live in a strange goods.

Pretending to be careless and walking to the counter where the blue ore was placed, Zhang Tianjiu casually pointed with his chin and motioned to the fat shopkeeper not far away: "Boss, how can this stone be sold?"

The fat shopkeeper glanced at Zhang Tianjiu, pouted and said, "This is a sword grinding stone that a down-and-out sword cultivator left with me as a mortgage a few years ago, if you like it, take a medium-grade source stone." ”

Sharpening the swordstone!

Zhang Tianjiu almost jumped up.

It is simply mad that such a precious Biyun Ore rough stone is actually used by you to sharpen your sword.

Zhang Tianjiu's strong emotional fluctuations finally aroused Wei Wuya's curiosity: "Ninth Master, this stone is very important to you?"

"Very important, do you know where else to find it?"

Zhang Tianjiu was overjoyed in his heart, but Wei Wuya's next answer poured cold water on his head again.

"The Ninth Master doesn't know, sword cultivation has always been relatively special, according to the different attributes of its cultivation exercises, the quality structure of the natal sword is also different, and the sword grinding stones used by different sword types are also different, so how this stone was obtained, except for the sword cultivator himself, I'm afraid no one knows. ”

Zhang Tianjiu nodded thoughtfully.

I didn't feel so disappointed, this time I was able to get such a large piece of Biyun ore, which was already a huge bargain.

Bring it back to the technology world and hand it to Amy, at least he can refine about ten grams of Bixanin stock solution, which can fully meet his needs for more than half a year.

Zhang Tianjiu was so excited that his palms were sweating, and he hurriedly threw out a medium-grade source stone, and he couldn't wait to pick up the stone when he reached out.

"Bang dang!"

Almost at the same time, two more medium-grade source stones smashed on the counter, and a cold voice came: "This sword grinding stone is a bit interesting, this son wants it." ”

Zhang Tianjiu turned his head suddenly, and saw a young man in brocade who was no more than fifteen or sixteen years old, slowly pacing, it was one of the group of sword cultivators just now.

Holding back the strong killing intent in his heart, Zhang Tianjiu turned around calmly with a calm face, just blocking the Biyun Stone behind him, and said with a smile: "Little brother, I have already bought this sword grinding stone." ”

If the environment was changed, Zhang Tianjiu would definitely not say half a word of nonsense, and he would not hesitate to smash this young man's sword cultivation into a pulp.

Biyun stone is too important to him, no matter who dares to rob it, there is definitely only a dead end.

But it was precisely because of this that Zhang Tianjiu couldn't help but kill without saying a word in Bai Zecheng, because he didn't want to make any extraneous branches.

The brocade-clothed young man sneered, as if he had already made up his mind and said, "If you say it, you have to ask the shopkeeper." ”

When this young sword cultivator just walked over, the fat shopkeeper's eyes lit up, and when he heard his words, he immediately smiled without hesitation: "Young Master Jiang, what are you talking about, you can take this sword grinding stone directly if you like it, how can I accept your money." ”

After speaking, the fat shopkeeper waved his hand, and actually swept Zhang Tianjiu's medium-grade source stone directly to the ground, and at the same time said in an unkind tone: "This fellow Daoist, I'm sorry." ”

The brocade-clothed boy smiled faintly: "Look, I said you can't buy it." ”

Wei Wuya said softly: "Ninth Master, this person is a disciple of the Heavenly Sword Sect. ”

Zhang Tianjiu raised his eyebrows slightly, the rudder of the Heavenly Sword Sect was the veritable boss of Bai Zecheng, no wonder the shopkeeper was so stammering.

It's just that today, let alone a disciple of the Heavenly Sword Sect blocking it, even if the Heavenly Sword Sect Master comes in person, he will have to take this piece of Biyun ore with him.

Facing the sneering gaze of the young man in brocade, Zhang Tianjiu smiled, and with lightning speed, he directly turned around and stretched out his hand to wipe it, and put the blue marble into the storage ring.

The action is done in one go, so fast that others can't react at all.

The handsome face of the young man in brocade immediately became gloomy, he reached out and held the hilt of the sword, and a fierce sword intent broke out of his body, and he said coldly: "Take it out." ”

Zhang Tianjiu smiled calmly: "What if I don't take it?"

"Then die. ”

The young man took a step forward, and the whole person seemed to have turned into an indestructible sword, firmly locking Zhang Tianjiu.

The movement on the counter finally caught the attention of the others.

Several other Heavenly Sword Sect disciples who came with the brocade-clothed boy also quickly gathered around at this time.

One of the burly middle-aged men frowned, patted the brocade-clothed young man on the shoulder, and said, "Young Master Jiang Feng, whoever dares to bully you, I will teach him a lesson for you." ”

Known as Jiang Feng's young man, he glanced at Zhang Tianjiu with disdain: "It's just a garbage in the mage realm, why bother the sixth uncle to do it, I can take care of him with one sword." ”

The middle-aged man laughed: "It is worthy of being the son of Master Jiang Helm, and he really has the true character of sword cultivation, since Gongzi Jiang is interested in playing, then this bald boy will be handed over to you to practice." ”

As the words fell, several other Heavenly Sword Sect disciples also let out a burst of laughter.

He took the initiative to retreat more than ten meters back, leaving a large enough space for manipulation.

From beginning to end, these people didn't take a serious look at Zhang Tianjiu once.

Compared to other monks, sword cultivators are more sensitive to mana fluctuations.

The mana fluctuations on Zhang Tianjiu's body, which was only equivalent to that of a middle-level mage, naturally couldn't escape their divine sense.

It's just that this bald monk doesn't know whether he lives or dies, and he actually dares to offend the son of the Jiang Helm Master, I'm afraid that if he doesn't die, he will have to shed his skin.

"Hey, you said, how many swords can Jiang Gongzi take down that guy?"

"I guess the three swords......"

"Three swords, how can you use so much, Jiang Gongzi has already practiced the sunset sword technique to the fifth layer, I'm afraid that one sword will be enough for that guy." ”

"I see that bald head is calm, how can I say that he can hold up to two swords. ”

"Then let's make a bet, I'll give you five medium-grade source stones......"
