The Dan furnace fire was raging, and heat waves swept out, and the temperature in the entire secret room was as high as nearly 100 degrees.

After waiting for a long time, even the faces of everyone who were masters of the Yudan Stage slipped beads of sweat, but no one complained, their eyes were fixed on the center.

Mu Beipan sat in front of the Dan furnace, holding the magic trick motionless, his face was serious, and his attention was extremely concentrated.

Next to him, the pile of spirit stones emitted a pale blue light, providing him with a steady stream of spiritual power.

Master Wen and Lu Lao were divided into two directions, and they just formed a triangle with Mu Bei, and the fire of True Yuan continued to emit from the Dan furnace in their hands, which was also solemn and abnormal.

At this time, three days have passed since the start of alchemy, and almost all the alchemy materials have been added one by one, and there is a slow smoke on the Dan furnace, and a fragrance can already be smelled.

"Medium and high fire, concentrate on oneness, I am ready to superimpose the fourth magic trick and add the last main medicine 'Ning Danguo'!"

As Mu Bei snorted, Master Wen and Lu Lao increased their strength in their hands, and the flames under the Dan furnace burst into flames.

The magic trick in Mu Bei's hand changed rapidly, and one spirit after another was played, which was the long-lost technique 'Xuantian Seven Changes'!

As he entered, the Dan furnace began to rise into the air and hover, and the furnace began to make a thunderclapping sound, and the reaction was violent.

A burst of tangy danxiang slowly overflowed, making people smell light and have a fluttering feeling.

"Now it has entered the medicinal property purification period, it will take two and a half days to complete, and this is also the period when my true yuan output is the most violent, don't relax, send me true yuan at any time!"

With the experience of the last time, Mu Bei has mastered it this time, and the alchemy has been completed in one go until now, and his method has changed again, and he has continuously played thousands of spiritual decisions one after another.

As he finished saying this, two people came behind him in an instant, one of them holding one hand against his back, ready to deliver the true yuan to him at any time.

"Extract the essence, remove impurities, enter the Dan fire, and condense the Dan type!"

The fragrance emanating from the Dan furnace became stronger and stronger, and the slightest thunderous sound came out, and the overflowing Dan Qi formed a dragon and tiger phantom above the Dan furnace!

"It's going to be done! It's going to be done! I've seen it in ancient books, when the 'Dragon and Tiger Crossing Erdan' Dan is completed, there is a burst of thunder in the furnace, and the Dan Qi turns into a dragon and tiger phantom and is entrenched above!

One of the Dharma Protectors on the side stared at the Dan Furnace without blinking his eyes and muttered. Although I was mentally prepared before, when I really wanted to succeed, I still couldn't suppress the joy in my heart.

At this time, everyone was impressed with Mubei, and the previous contempt and suspicion had long disappeared at this moment.

In their eyes, Mu Bei's exquisite alchemy techniques, as well as the meticulous handling of alchemy details, are only seen in their lives.

(My good man, in this way, it really can be successful! Jin Dan is hopeful! Jin Dan is hopeful! Fortunately, I chose to defend him last time, which is really the most correct step in my life!)

Xu Minghai, the director of the Political Department, had a feverish look in his eyes, and his state of mind after hundreds of years of cultivation could not suppress the agitation in his heart at this moment.

The other seven people also have smiles on their faces now, and Danxiang has appeared, indicating that success is in sight.

Time passed, and it was another three days.

At this moment, the phantom of the dragon and tiger on the Dan furnace began to solidify, and there was a faint sound of a dragon chanting and a tiger roaring!

"Xuantian Sevenfold Transformation! Seventh Fold---- Ten Thousand Transformation Pills!"

Mu Bei played seven seven forty-nine magic tricks in a row, pushing the Xuantian Sevenfold Change to the seventh change!

Rumble!

The Dan furnace, which was originally floating and spinning, fell heavily in place, and the spiritual light of the furnace body flowed, which was a manifestation of the extreme change.

The elixir will be completed, the sky will change, and a cloud and mist cyclone will begin to form, and the thunder will loom, with the cloud and mist cyclone as the center, as if the white paper is stained with ink, and it will begin to become black, as if there is a thunder and thunder in it!

"Everyone, the thunder tribulation is coming, quickly use the trick of deceiving the sky!" Mu Bei shouted.

The other eight people moved in unison, and the magic tricks in their hands were played in unison, isolating the induction of the clouds to the Dan Qi.

The clouds in the sky had not yet fully formed, and gradually began to dissipate as the magic trick entered.

Everyone sighed, this most dangerous level had passed, and the original tense anger was slightly relieved.

The dragon and tiger phantom pill elephant formed by the condensation of Dan Qi above the Dan Furnace began to change, and it was absorbed into the Dan Furnace in a moment, and all the Dan Qi was also inhaled without leaking.

At this moment, the clouds and mist in the sky were about to dissipate, and at the last moment of disappearance, a small thunderbolt fell from it!

"It's not good! Thunder Tribulation!" Mu Bei Shenjue Ling, just played the last trick, and reminded everyone loudly.

But at this moment, it was too late, the speed of that thunder was too fast, and it fell straight down, penetrating the prohibition on the periphery of the alchemy room, and slashed on the alchemy furnace at once!

"It's too late!

"Don't!"

"No!"

Everyone else rushed to the Dan Furnace, and some people even wanted to desperately pounce on it to protect the Dan Furnace.

But it was too late, and the thunder tribulation struck the Dan furnace and exploded directly on it.

Everyone stepped forward to see that a big hole had been split in the Dan furnace, and it was pitch black inside. This high-grade magic weapon Dan furnace has been destroyed, and there is still thunder on the surface of the furnace body, which is terrifying.

This is a catastrophe! If you are not careful, it is not a joke to get contaminated!

"Alas...... It seems that this time it was a failure. Wen Lao's face was full of regret and sighed.

No one expected that the clouds that were about to disappear would give them a big gift like this, splitting everyone who was originally happy back to reality.

"Just... Is this all over?" the only woman among the ten spoke, her eyes full of loss.

Seeing this situation, several people thought that it was okay for Mubei to be fine, and next time they had gathered the alchemy materials, they could refine it again, but they would have to wait for a while.

Mu Bei's eyes kept staring at the broken Dan furnace that fell to the ground, and a smile gradually appeared in his eyes, and he said, "Everyone, maybe it's not the time to be disappointed. ”

When the others heard this, they were a little confused, now even the Dan furnace has been destroyed, and the pill that will be refined has been destroyed, how can they not be disappointed?!

"Borrow a gourd. Mu Bei said to the refining master.

The old man looked at Mu Bei with a smile, and with some doubts, he took out the purple gold gourd and handed it to him.

After taking the gourd, Mu Bei asked for advice on how to use it, and then opened the mouth of the gourd, and controlled the gourd to start absorbing the thunder on the Dan furnace!

Soon, the thunder was absorbed by the gourd, and he grabbed the lid of the Dan furnace.

A brilliant light emanated from it without warning, and an incomparably rich aura diffused.

Everyone was amazed, and the mood that had fallen to the bottom was instantly raised.

"Is it difficult?!"

Looking into the Dan furnace, twelve golden grapes-sized pills were lying quietly in it, crystal clear, easy to turn, and you could vaguely see a dragon and a tiger fighting in each pill!

Different from the last refining, there were vivid lines on the surface of these twelve pills, and their shapes were strange, but they seemed to be very mysterious.

"Dan Yin Dao Pattern! Excellent!" Master Wen exclaimed, already unable to help himself!
