He took out seven copper coins from the pile of copper coins and put them on the table in a row, and clamped the seven copper coins with refining talismans, and then Zhang Yu pinched out a magic trick with both hands, and began to draw talismans out of thin air, pointing to the seven copper coins placed on the table, and chanted softly: "Take Qi as the flame, and use the talisman as a furnace - refining!"

The fourteen refining talismans instantly became natural, and suspended the seven copper coins to a height of more than a foot from the table, and the blue flames wrapped the seven copper coins, calcining them constantly, and the air became distorted.

Fortunately, Zhang Yu was prepared and wrapped in yin and yang qi, which did not cause serious consequences.

It is unimaginable that a few runes made of yellow paper can burst out at such a high temperature, if there is no protection from yin and yang, maybe the villa will be ignited.

Zhang Yu's eyes were fixed on the copper coins, only to see that they were burned red, and there were signs of melting gradually!

It seems that the heat is still not enough, Zhang Yu frowned, he tried to inject yin and yang qi into it, but he didn't expect that as soon as he injected it, the raging flame was like pouring gasoline, and the temperature rose again.

The seven copper coins melted at this point, and they mixed into a reddish mass of copper that sometimes converged and sometimes split into seven separate masses. Between this division and combination, there is actually a kind of heaven and earth truth, which makes the original ordinary copper liquid faintly reveal a bit of mysterious atmosphere.

The yin and yang qi in the dantian were consumed very quickly, Zhang Yu was still patiently calcining, observing, I don't know how long later, the yin and yang qi in his dantian were almost consumed, and he was sweating profusely and persevered.

At this moment, seeing that the yin and yang qi of the dantian were exhausted, suddenly a light blue light flashed in the copper liquid.

Great, right now, Zhang Yu was ecstatic, he opened his mouth violently and bit the tip of his tongue, squirting a mouthful of blood on the tip of his tongue at the copper liquid. The blood on the tip of the tongue is the thing of human yang, and it quickly hit the copper liquid, and the copper liquid instantly solidified into the previous copper coin shape that was round on the outside and square on the inside under the action of the red blood.

What's even more amazing is that the seven copper coins are welded together to take on the appearance of a small sword. And those seven copper coins no longer have a mottled patina. It was smooth and shiny, like a new coin that had just been made.

The words originally engraved on the copper coins, such as Hongwu Tongbao and Zhengde Tongbao, also disappeared collectively at this moment, making it impossible to see which dynasty and which generation they were the products of.

Zhang Yu pinched out a magic seal with both hands, and recited the French text of refining in his mouth: "The upper dynasty Jinque covers Kunlun, regulates the discipline, and controls the Qiankun"

The sound of his incantation was not slow or hurried, revealing a special magical power.

With the recitation of the French, Zhang Yu kept drawing runes in the air with his hands according to the method of refining the copper coin sword, and then advanced the solidifying copper coin sword, as the runes were integrated, the runes actually slowly showed a light blue light, and the seven copper coins appeared on them: Broken Army, Greedy Wolf, Wuqu, Wenqu and other names of the Big Dipper

The words on the seven copper coins are either vigorous and powerful, or sharp, or quaint and atmospheric, and their styles are very different, but they are quite appropriate to the stars they represent.

When Zhang Yu finished playing the last rune, he shouted: "The rune is finished, the instrument is completed!"

Almost at the same time, he squirted a mouthful of blood from the tip of his tongue again, and the names of those Big Dippers instantly merged into the copper coins.

The golden sword qi burst out, dazzling! It kept buzzing, as if a new life had descended on this world.

What Zhang Yu didn't know was that at this time, there was a change in the sky, and the wind and clouds converged, attracting many people from the Xiuzhen sect to stop and watch.

"Could it be that something happened to the strange treasure?" Some of the heads of the big sects pinched their fingers and frowned, and many people from the Xiuzhen sect were sent to the imperial capital to check.

Fortunately, this kind of vision disappeared in an instant, making those cultivators sigh, no matter how powerful they were, it was impossible to calculate their location by relying on such an instantaneous vision.

When the light disappeared, Zhang Yu found a beautiful copper coin sword appear in front of him.

"Successed"

This time, his spirit was tense from beginning to end.

In fact, he was also lucky, and after that, when he made the copper coin sword again, he would find that the failure rate was so high that all the remaining copper coins were turned into pieces due to various circumstances, and he sighed.

The yang energy on this copper coin sword is strong, murderous, and heart-to-heart, so that Zhang Yu can't put it down, but unfortunately by this time, the yin and yang qi in Zhang Yu's dantian has long been exhausted, pick up the copper coin sword and enjoy it for a while, he reluctantly put the copper coin sword on the table.

For cultivators, the Money Sword is one of the lowest level magic weapons. But for Zhang Yu, this is a good thing, not to mention that the combat power has risen a lot, the copper coin sword is still very strong, after Zhang Yu cultivated the Heavenly Master's secret book to recover, he injected the yin and yang qi into it, and unexpectedly found that even if the one-meter-long sword was released, the copper coin sword would not be damaged at all.

"It's better to call you the Big Dipper Sword" Zhang Yu played with the copper coin sword over and over again, and simply gave it a new name. It can be seen that he is in a pretty good mood at this moment.

After playing for a while, Zhang Yu put away the Big Dipper Seven Star Sword and suddenly received a call from Li Song.

"Brother Li, how do you have time to call me?" Zhang Yu asked with a smile after answering the phone. It's been months since we last said goodbye.

"I have something to tell you, recently there is a wanted criminal in the imperial capital, cultivated as the eighth layer of qi refining, he likes soul refining the most, he is extremely vicious, if you encounter it, you must notify me as soon as possible." Li Song's serious voice rang out from the phone.

"This" Zhang Yu couldn't help but be stunned when he heard this, thinking to himself, what does this have to do with me?

After Li Song finished speaking, he patted his head, and then he remembered that Zhang Yu didn't know about the worldly affairs of cultivators.

"It's all because I'm too confused, I'll explain it to you!" Li Song said with a smile.

Through Li Song's explanation, Zhang Yu understood that all the cultivators in Huaxia were registered in the Special Operations Department and were controlled by the state.

Of course, there are also cultivators who sneak into the country and do illegal things, especially in recent years, the Dongying people have been sending people to Huaxia, because the elders are almost the same, so it is particularly difficult to control.

Once this kind of smuggling is discovered, no one will be held accountable even if they are killed. Of course, it is not excluded that some sects will come to take revenge, but generally speaking, there is nothing to do in Huaxia territory.

And that wanted criminal named Liu Yi hunted cultivator disciples everywhere, collecting their souls and refining ghost servants.

After being known by all the major sects, they all sent people to hunt him down, and Liu Yi hid everywhere in order to avoid pursuit. Someone happened to see that Liu Yi came to the imperial capital, and out of love for Zhang Yu, Li Song called him.

"Brother Li, don't worry, I'll be careful. Zhang Yu said gratefully, after all, the imperial capital is so big, and the chance of encountering it is almost zero, but he is still very grateful to Li Song for reminding him.

"Well, I'll also give you a routine notice, okay, remember to come to our special operations department to play when you have time!" Li Song said with a smile, at this time he didn't forget to recruit Zhang Yu, and the two chatted for a few words before hanging up the phone.

"The eighth layer of qi refining, soul refining, it's a bit interesting!" Zhang Yu said as he played with the Big Dipper Seven Star Sword.
