Since this is the case, Xiao Chen did not hesitate, and when the auctioneer announced the start of the bidding, he immediately quoted his price, which was still 10 million taels of gold.

The chaos that Xiao Chen originally imagined did not appear, and the people below were still numb to Xiao Chen's bid, and the only people who felt anxious were those who put up the auction.

Their current mood can be said to be mixed with joy and sorrow, they are afraid that Xiao Chen is just a mouthful, and they also fantasize that Linlang Pavilion has such a big reputation, and it is impossible to do something treacherous.

After the auction ended, someone immediately brought the three items that Xiao Chen had auctioned to Xiao Chen's room and examined them carefully. The inner pill of the colorful flame mang, the lower-grade spirit stone, and the high-grade cold iron, confirm that there is no quality problem.

Xiao Chen didn't go out immediately, handed the cold iron in his hand to Xi Jiao and said, "Can you refine it here?" I feel that there are two people outside, staring at me all the time. ”

Ji Jiao said lightly: "The perception is not bad, there are indeed two flies hiding outside." To refine this high-grade cold iron, there are no special requirements for the location. ”

That piece of cold iron was the size of a schoolbag, and when Xiao Chen held it in his hand, he felt that it was at least more than two hundred catties, and his pitch-black appearance looked extraordinarily thick.

Jiaojiao easily took the cold iron in her hand, easily weighed it a few times, and threw the cold iron into the air. A white flame shot out from her palm, enveloping the cold iron in the air.

Xiao Chen carefully observed Jiaojiao's every move, and memorized every step she took. This high-grade cold iron refining technique is an extremely rare secret art on the mainland, and it has always been in the hands of a small number of people.

The Great Qin Empire only has Tiangong Mountain Villa, and with such technology, it is a good learning opportunity in front of him.

The white flame burned slowly, and Xiao Chen found that this flame was extremely strange, without a trace of the ferocity and domineering of ordinary flames, but made people feel a little warm.

What kind of flame is this, Xiao Chen thought suspiciously.

Ji Jiao had the heart to teach Xiao Chen, and maintained the flame over and over again, while explaining: "This flame is not the flame refined by the martial artist itself, it is a human fire that has existed in heaven and earth for a long time, called the ghost bone fire. ”

"Back then, the Thunder Emperor Sangmu was subdued when he was cultivating in the Nine Shades Purgatory, and after he fell, this flame was handed over to me. ”

It is really eye-opening that there is such a strange flame between heaven and earth, but I don't know what the beauty of this human fire is.

Xi Jiao went on to explain that there are four very cherished flames between heaven and earth, namely human fire, dragon fire, ghost fire, and heavenly fire.

In the Tianwu Continent, on the territory of millions of miles, there are a total of nine huge dragon veins, and at the end of these dragon veins there is the fire of the imperial road.

Of the nine dragon fires, five of the ones that were already known on the continent were taken away, and the remaining four were never found. In addition to the reason why this dragon fire is buried 10,000 meters deep underground, and the environment is extremely harsh, what is more important is that the remaining four dragon veins will change.

Legend has it that the owner of the dragon fire can open up the Great Imperial Dynasty, and it is impossible for anyone who is not the Ninety-Five Honorable Personality to find the dragon fire.

Ghost fire, existing in the extreme yin of the world, is mysterious and unpredictable, and has the power of gods and ghosts. There are two places in the Extreme Yin Land on the mainland, namely the Xuanyin Cave Xuan, which is tens of thousands of meters deep, and the Nine Hells Purgatory, which is known as the hell on earth.

These two places are forbidden places on the mainland, but the ghost fire that exists in them has been taken away by the predecessors thousands of years ago. It's just that over the years, ghost fires have rarely appeared in the world, and outsiders don't know whether new ghost fires have been bred in the two places of extreme yin.

Heavenly fire, recognized as the most terrifying flame in the world, is said to be a flame that can refine the entire world. This kind of flame is only recorded in the history books, and it was owned by the Tianwu Emperor, who opened up the Tianwu Dynasty to unify the continent 10,000 years ago.

With the fall of the Tianwu Dynasty, this kind of earth-destroying flame has long disappeared in the long river of history.

As for the last human fire, it is not a natural fire, it should be said that it was not formed by pure natural forces. It is a special flame formed by the power of the martial god after the most powerful warrior in the world, after the martial god sits, the form and god are destroyed.

After the fall of the Martial God, the huge energy that exists in his body will not disappear with it. After the precipitation of this huge energy over time, it will form all kinds of strange flames, called human fire.

After listening to the introduction, Xiao Chen only felt that his heart was rippling, and all kinds of strange things about the size of the world were definitely not what could be seen in this small Mohe City.

I can't wait to go out immediately, but it's a pity that the ten-year appointment has not arrived, and what Xiao Chen promised will naturally do his best, and it is impossible to leave now.

"Is there really a martial god in this world?" Xiao Chen asked.

Ji Jiao's eyes kept staring at the cold iron wrapped in flames, and replied: "Of course, although it is rare for countless ghosts in the world to reach the realm of martial gods, it is not nothing. ”

"And according to legend, there is also a mysterious existence above the martial gods. ”

Xiao Chen continued to ask: "That Thunder Emperor Sangmu, did he break through to the Martial God?" ”

Tsundere said lightly: "When you kick the door and are killed, you can only say that your destiny is difficult to do." ”

Xiao Chen's heart was difficult to calm down for a long time, as powerful as the Thunder Emperor, he was killed in the end, it was really hard to believe, could the person who killed him be the legendary Martial God.

Tell Ji Jiao the doubts in her heart, and Ji Jiao just said lightly: "These are not what you are thinking about now, although you have inherited the inheritance of Lei Mu Sword, you do not bear the responsibility of avenging him." ”

This seems to be a little wrong, how can there be a benefit for himself for no reason in this world, and he doesn't have to bear any responsibility, which surprised Xiao Chen.

Xiao Chen has always been more worried than happy about the appearance of Jiaojiao, and when he heard her say this at this moment, he was also a little relieved.

But Ji Jiao's next words made Xiao Chen almost vomit blood, "Although you don't have to bear the responsibility of avenging the Thunder Emperor, it's hard to say whether trouble will find you, so the owner of the scrap wood should become strong as soon as possible." ”

Xiao Chen was completely speechless, there were too many mysteries on Xi Jiao's body, why did the sword in the Thunder Emperor's Cave Mansion break, who killed the Thunder Emperor, and how did he become her master.

Until now, Xiao Chen can be said to know very little, and he usually doesn't know how to ask Jiaojiao, but today he revealed something, but it is also confusing.

Whew!

The black black iron wrapped in flames had turned into a liquid molten iron at this time. It can be seen that this ghost bone fire has a huge contrast with the mildness on its surface.

The conversation between the two was only five minutes, and this high-grade cold iron had already turned into a ball of molten iron, if it was calcined with Xiao Chen's Purple Thunder True Fire. It takes at least half a day, and the huge gap can imagine the strength of the ghost bone fire.

Jiaojiao snorted softly, and her lovely face once again showed that serious look, which made people feel a little unbearable.

In her right hand, a glowing broken sword suddenly appeared, swinging at the molten iron in the flames.

Suddenly, the sparks in the box were shining, and a little flame made a violent explosion in the air, and Xiao Chen hurriedly hid behind Xi Jiao when he saw this.

Every time a wisp of flame was shot, there was one drop less of molten iron in the ghost bone fire, and Xiao Chen secretly said in his heart, this should be to remove the impurities in the high-grade cold iron.

Generally, the quality of cold iron is of the highest grade, and the impurities contained in it are very few, and I want to remove the impurities without wasting the essence of cold iron.

In addition to the need for extremely high eyesight, it is more about the speed of the knife. It seems to be a static molten iron, but in fact, it is flowing at a high speed inside.

Xiao Chen released his divine consciousness and entered the inner world of molten iron, and in front of him was a fiery red world, even if he entered Xiao Chen's divine consciousness, he could feel the terrifying temperature.

In this fiery red world, clusters of Xiao Chen's unknown substance kept squeezing and flowing. Xiao Chen observed carefully for a long time, and finally found some suspicions.

Those pure black substances should be the essence of cold iron, and from time to time, in addition to the black substance, some gray residual iron is removed.

The short sword in Jiaojiao's hand was as precise as those precision instruments in the previous life, and when the gray substance was removed, all those essences were preserved without the slightest waste.

Xiao Chen retracted his consciousness and looked at Xi Jiao's cute little girl-like face again, his eyes full of admiration. This boiling Jiao can not only refine medicine, but the hand that is now exposed is obviously not something that ordinary people can do.

How many secrets are hidden in this little girl's body, can I really trust her completely?

"It's done!" said with some joy.

Withdrawing the ghost bone fire from her hand, with a flick of her hand, a fist-sized piece of cold iron appeared in her petite hand, and a look of joy appeared in her eyes.

"Scrap master, here you go. ”

Xiao Chen took the top-grade cold iron handed over by Jiao, and his heart was extremely happy, this fist-sized top-grade cold iron was more than a hundred times stronger than the top-grade cold iron.

But at this time, Xiao Chen found that the expression on Xi Jiao's face was even weaker, and a fire broke out in his heart for no reason, "You lied to me before, right, your face is so bad, you must have done something dangerous when you went out before." ”

"He also lied to me that the physique of the sword spirit is different from that of humans, so you can't judge things by looking at your face, and your current situation is simply caused by excessive continuous exertion. ”

Ji Jiao quibbled: "You actually look at a sword spirit from the eyes of a human being, you are really a waste material and a stupid person, you can solve the flies outside." ”

After finishing speaking, as if she knew that she was wrong, she got into the Qiankun ring and never came out.

Xiao Chen sighed in his heart, no wonder your sister is called Xijiao, the Thunder Emperor really didn't give her the wrong name, this tsundere attribute is still averagely high.

Releasing his divine sense, he carefully observed the two Tang family disciples hiding outside again, and the corners of Xiao Chen's mouth hooked up a sneer. If you want to fight the idea of this young master, you guys should be a little tender.
