Zhang Yue studied the jade box for a while, but couldn't find a way to open it, so he simply clasped the jade box with both hands and broke it to both sides.

The first time he used his own strength, the jade box did not move, and the second time Zhang Yue infused his internal strength.

How powerful the martial arts master's fingers are, Zhang Yue said without exaggeration at this time that ten fingers can break the steel. However, with such a powerful force, the jade box only opened a small crack slightly.

As soon as a little crack was revealed, a foot-long essence light flew out of the jade box, and the cold air was cold, approaching Zhang Yue's eyebrows.

Zhang Yue reacted extremely quickly, his body fell backwards, the cold light swept past his eyebrows, and flew out more than twenty meters in an instant, until he hit the stone wall.

The cold light wrenched silently on the stone wall, and dropped a pile of rubble like cutting tofu, and then turned around and flew in the other direction.

What is this? Zhang Yue was shocked, this cold light was incomparably sharp, and the hard stone couldn't withstand its slight sharpening, but fortunately, he flashed fast just now, if he was stabbed in the center of his eyebrows, he would shudder when he thought about it.

At this time, the Dan furnace sounded: a special material was found, which can be used to refine the Sword Pill.

Zhang Yue searched his memory and found that the sword pill is a very special kind of flying sword, which is made by the method of alchemy, compared with ordinary flying swords, the sword pill is hidden in the body, and it can even be used as a part of the body, which is extraordinary.

Since the Dan Furnace decided that this cold light belonged to the Dan material, it was easy to deal with.

Zhang Yue flew to chase after the cold light, although the speed of the cold light was fast, but he had no intelligence, he just flew around aimlessly, and he would not deliberately dodge, and was quickly blocked by Zhang Yue.

With his left hand, he grabbed the cold light into his palm, disappeared in an instant, and was absorbed by the Dan furnace.

The Dan furnace then gave the Dan recipe for refining the sword pill:

Dan name: Jian Dan

Grade: Congenital Elementary

Efficacy: Water attribute flying sword

Dancai: Han Yan sword embryo

Danhuo: True Yuan

Dan Yin: Han Yan Sword Technique

It turned out that this thing was the sword embryo of the Han Yan Sword, but refining the sword pill also required the Han Yan Sword Technique, Zhang Yue pondered, and took the jade box that had just been thrown on the ground back in his hand.

When the Han Yan Sword Embryo flew away, it seemed to have broken some kind of seal, and the jade box became very easy to open, and on the back of the lid of the box, Zhang Yue found many small words like ants crawling, Zhang Yue didn't know a word, but this was not a problem for the Dan Furnace, the Dan Furnace shook slightly, prompting the discovery of a special spirit body, and asking if he had refined the Lingjue Pill.

Zhang Yue had long been familiar with the Lingjue Pill, and immediately confirmed the refining.

Soon, Zhang Yue had an extra sword trick in his mind, and at the same time knew the origin of this jade box.

Thousands of years ago, when the cultivators had not left, there was a person from the White River who inadvertently obtained a piece of ice pith, and he fused several materials such as cold iron and quicksilver to refine this cold sword embryo, and sealed the sword embryo in a jade box, and placed it in the cold spring spring to recuperate, and planned to take out the official refining flying sword after a hundred years.

The people of Baihe never came back after leaving, maybe it was an accident, maybe there was something wrong and they were in a hurry to leave, and they didn't have time to take the jade box, in short, this jade box and the cold sword embryo had been placed in the spring for thousands of years until they were discovered by Zhang Yue.

Dan Furnace asked, the conditions for refining the Sword Pill have been met, do you want to start refining?

Hey, you can actually refine it, but isn't your true yuan still usable? Zhang Yue tentatively confirmed the refining in his mind.

The Dan furnace is worthy of being a thing against the sky, after Zhang Yue confirmed the refining of the sword pill, the true yuan that can only be sensed but cannot be used in the dantian magically disappeared, and then the Dan furnace shook violently, the furnace lid opened, swallowing the cold sword embryo like a monster, and closed it with a snap, and then the purple light was great, and the patina on the furnace body fell off in large pieces, revealing countless simple patterns.

Zhang Yue's true yuan turned into a cyan brilliance, flowing along the lines on the furnace wall, and there was a muffled thunderous sound in the Dan furnace, and sometimes there was a huge noise, as if thousands of troops were fighting inside.

In the past, the alchemy speed of the Dan furnace was very fast, but this time it lasted for a long time, and it could not be completed for a long time, and the cyan brilliance on the furnace wall gradually weakened.

Could it be that the true yuan is not enough? Zhang Yue tried to cultivate the qi induction technique, and generated another drop of true yuan in the dantian, and sure enough, as soon as the true yuan appeared, it was immediately sucked by the dan furnace, and at the same time reminded Zhang Yue that he still needed more true yuan.

Zhang Yue simply sat on the edge of the pool, refining the true yuan day and night for the Dan furnace to consume.

I thought that one day would be enough at most, but I didn't expect that this sitting would be more than a whole month, and the Dan furnace finally announced that the sword pill refining was completed after a thunderclap-like movement.

Take the sword pill in your hand, and carefully look at this "pill" that has been successfully refined after suffering a lot.

The sword pill is only the size of a dragon's eye, the whole body is silver, and there is a little blue light on it, which looks mysterious, pinched in the fingers, as if pinching an ice pill, and the tentacles are cold.

"How is this thing going to be used?" Zhang Yue asked the Dan Furnace with his mind.

Dan Lu's reply was like an elixir, just swallow it.

This-Zhang Yue hesitated for a while, plucked up the courage to swallow the sword pill into his stomach in one bite.

The sword pill entered the abdomen, and instead of turning into sword light as Zhang Yue feared, it turned into a mess of the stomach and intestines, but turned into a chill, and went straight to Zhang Yue's dantian, entrenched in it and never moved again.

Trying to use the sword technique to drive, the sword pill shook for a while, and finally lazily responded to Zhang Yue's command, turning into a wisp of cold qi, flowing along a meridian, and finally flowing into Zhang Yue's right index finger.

With a flash of cold light, a silver snake rushed out from the tip of his index finger, circling flexibly in the air with Zhang Yue's mind.

"Go!"

Zhang Yue shouted, and the silver light rushed towards a stone pillar, and as soon as he rushed through, the stone pillar broke in two.

"Back. ”

With an order, the silver light retracted into his body and was still suspended in the dantian.

Good baby, really good baby, Zhang Yue is endlessly happy, this is a flying sword, a treasure that can only be used in the innate period, I can't imagine that the Dan furnace will let me have it in advance during the qi induction period.

Imagine that when you move your sword trick, the silver light is separated from the body to kill the enemy, who can stop it under the Heavenly Master?

I also wanted to try out the Cold Mantis Sword again, but I sensed it, and I had already consumed a drop of my true yuan in the few seconds just now.

It seems that this cold sword can't be used lightly, and he still has to accumulate true yuan, preparing to break through the innate nature, and the true yuan can not be easily consumed.

After the joy, Zhang Yue suddenly patted his head, oh no, after so long in the belly of the mountain, the family should be in a hurry.

Thinking of this, Zhang Yue couldn't stay any longer, the qi induction recipe had been completed, the sweet green fruit had been eaten, and he had also won the Han Claw Sword, and there was nothing to be nostalgic about in this place.

Removing the stones blocking the road, Zhang Yue walked out along the cracks in the stones, and it didn't take long for him to see the dazzling skylight again.

After not seeing the sun for a long time, Zhang Yue had a feeling of not adapting, and it took a while to recover.

Mobile phones and other devices have long been out of battery, so turn on the solar panels while the sun is strong to charge your mobile phones.

Turn on the computer, connect to the Internet through the satellite locator, and turn on Tianxun. Suddenly, the beeping sound kept going, and a lot of news jumped out.
