"It's really annoying! What do you mean that I won't succeed on my own! If you want to stop the appropriation of our alchemy department, just say it, and you still have to go around thinking I'm a fool?!"

After Master Wen came out of the principal's office, his face turned blue with anger, if he didn't still have reason, he tried his best to control himself, and almost wanted to explode his true qi and destroy it.

This time, the vice principal talked to him, thinking that it was impossible for him to succeed in refining the 'Dragon and Tiger Crossing Erdan' with only the remnants of the recipe, and so far he had not only spent all his savings, but also spent a lot of money.

At first, after reporting to the federal government, there was a huge amount of funding every year, but then it was really unable to support this huge consumption, and the government funding had been stopped more than ten years ago, and until now it is only supported by the funds allocated by the college to the department.

Fortunately, the number of people in the alchemy department is very small, and it has been empty for many years, and it can barely support the cost of refining.

Landing at the door of the alchemy room, Master Wen was still angry and strode into the pill room.

"What's going on, why is Dan Qi so strong!"

He found an abnormality and saw Mu Bei, who was sitting on the edge of a quaint alchemy furnace, surrounded by dozens of high-grade spirit stones suspended around him, providing him with a steady stream of spiritual power, his hands changed and pinched, and one after another spells were played.

The fire under the Dan furnace is extremely violent, and there is a constant sound coming out of the furnace, and the changes are violent!

Looking at the remaining medicinal materials again, he found that the place where he had been stacked before was empty, so he reacted and hurriedly shouted towards Mubei:

"Mubei, what are you doing...... No, how could the alchemy technique he use be so similar to the rumored 'Xuantian Seven Folds' that had been lost! This Dan furnace is a top-grade magic weapon!"

Originally, I wanted to stop it, but when I saw Mu Bei's whole body perfusion, the magic trick in his hand was extremely exquisite, and there was already a trace of Dan incense overflowing from the Dan furnace, which was obviously in the middle of refining, and I was stunned for a while.

Suddenly, as Mu Bei hit the Dan furnace with seven consecutive spells, there was a slight thunderous sound in the furnace, and the overflowing Dan Qi formed a dragon and tiger phantom above the Dan furnace!

"Dan Qi is formed, the dragon and tiger are entrenched, and Dan is thundering! This is the sign of the preliminary condensation of the 'Dragon and Tiger Crossing Erdan'!"

Master Wen didn't dare to make a sound at this moment, he had refined this pill tens of thousands of times in the past hundred years, but he had never succeeded in refining it, and he had only touched the general clue.

I didn't expect that a young man who had only seen a few faces in front of him could do this!

Originally, after the principal talked to him this time, he had already moved the idea of giving up, but seeing this situation, the previous displeasure and helplessness were all forgotten.

He quickly looked around and acted as a protector for Mubei to make sure that no one would come to disturb him.

The light brain sounded out of place, he didn't look at it, he took it off directly, threw it away, and blasted it in the air with one palm.

Day and night alternated, time passed little by little, and three days had passed.

Mu Bei had already played tens of thousands of spiritual decisions, and finally, when a high-grade spirit stone ran out of spiritual power and fell to the ground, he threw the last main medicine 'Ning Dan Fruit' into the Dan furnace.

Another high-grade spirit stone consumed spiritual power, and Mu Bei instantly hit seven seven forty-nine spirit decisions, which is a subtle technique in the 'Xuantian Seven Transformations', with seven different spirit decisions as one, it can speed up the reaction efficiency between medicinal materials, and seven seven and forty-nine spirit decisions are played together, which will greatly shorten the refining time.

The alchemy furnace floated in the air, first rotating rapidly, and then gradually rotating slower and slower, tending to be stable, the dragon and tiger phantom on the Dan furnace became more and more condensed, the dragon was on top and the tiger was below, and there was a faint sound of the tiger chanting and the dragon roaring!

I saw Mu Bei get up and make a spiritual duel around each of the four directions of the Dan furnace at a very fast speed, and put it back on the fire in the far ground.

He threw out a few more flint stones and used his spirit to keep them to the size of a warm fire.

The refining has reached the stage of raising pills in the later stage, and the size of the furnace fire at this moment must not be wrong at all, otherwise the previous efforts will be wasted.

And so it passed for another three days.

The elixir in the furnace has begun to take shape, and it will not be long before it can be successfully refined.

But at this time, there were thunderclouds condensing in the sky, and they were about to rain down thunderstorms!

Master Wen also discovered the abnormality, and thought that the elixir above the fifth order was a thing against the sky, and when the refining was successful, it would be very likely to attract the Heavenly Tribulation!

He was shocked, he had never been in such a situation before.

(What should I do??The hundred-year-old wish is about to be fulfilled, but we can't let it be ruined under the eyelids!)

For a while, he thought of the principal, who was a super strong person in the Yuan Infant Stage, who could definitely withstand this catastrophe, so he wanted to use the art of sound transmission.

"Master Wen, my true yuan is not good, this trick of deceiving the heavens can only be performed by you, whether it succeeds or not, it can only depend on the will of heaven. ”

Mu Bei transmitted a spell to him, and if he was successful, he could hide the pill and Danqi that was about to be successfully refined, and deceive the heavenly thunder tribulation.

Master Wen was overjoyed, and according to the trick in his mind, a spiritual light went towards the sky calamity clouds, and the second spiritual light formed a light shield to cover the Dan furnace.

Dan Qi was blocked, cause and effect were cut off, and the clouds in the sky could not find their target, and began to gradually disperse.

It was only then that Mu Bei collapsed and sat down and began to close his eyes and breathe.

At this moment, the refining has been completed, and it is only necessary to open the Dan furnace to check.

Master Wen still didn't dare to relax on the side, protecting the Dharma for him, although he was excited in his heart, he still suppressed it.

A quarter of an hour later, Mu Bei finished breathing, got up and nodded at Master Wen, signaling that the Dan furnace was about to be opened.

"Up!"

A spirit duel was struck, the furnace was levitated, and a burst of white mist dispersed, and then a dazzling light came out of it!

What followed was a burst of fragrance, which made people feel a little ethereal after smelling it, and Mu Bei felt the restlessness of the true yuan in his body when he smelled it, and it seemed to be a little stronger!

Looking at the furnace, three golden pills the size of grapes were lying quietly in it, crystal clear, each exuding a rich aura, as if there were dragons and tigers fighting in it.

"Dragon and Tiger Crossing Erdan! Dragon and Tiger Crossing Erdan! Really refined! Still medium quality! Hahahaha!"

Master Wen was already in a state of his own affection at the moment, and he couldn't control his tears.

"It's your herbs, I'll take one and keep the other two for you." Mu Bei said to him.

"By the way, fellow Daoist, how can you refine this Dragon and Tiger Crossing Erdan, and your refining technique and that high-grade alchemy furnace?"

At this moment, Master Wen had changed his words to call Mu Bei a fellow Daoist, and he had a stomach full of doubts, wasn't this a freshman who didn't understand anything?

"My family is an ancient alchemy family, and they have been living in seclusion before. It's hard to say that there are too many, and the family has avoidance, so don't say much. ”

Mu Bei casually pulled a little bit and wanted to fool the past.

When Master Wen heard this, he had a look of sudden realization, the disciple of the ancient alchemy family, but also said in the past, at this moment he was already carried away by joy, and he didn't think about the doubts at all.

After that, Mu Bei refused Master Wen's invitation to talk to him about the way of alchemy, and hurriedly retired.

After he left, seven figures appeared in the sky above the alchemy room, all of them were strong people above the Dan Formation Stage, and one of them was the old man who had talked to Master Wen before.

"Lao Wen, what's the situation?, how did we sense that there was a calamity cloud condensation here just now, could it be that you are crazy and want to forcibly cross the Tribulation Ning Dan?!"

One of them asked him.

Master Wen was smiling at the moment, and he didn't say much, and took out a 'Dragon and Tiger Crossing Erdan' and held it in his hand.

"Look what this is!"
