Peerless Taoist

This was his previous life's Underworld God True Fire.    

Although it wasn't as bright as the sovereign level Heavenly Emperor True Fire in terms of quality, it still possessed extraordinary power.    

Once the Heavenly Emperor True Fire appeared, it would cause all flames to submit to it. If that was the case, the commotion would be too great. This wasn't what Lu Yu wanted.    

But even so, the terrifying aura of the True Fire of the Underworld God had deeply shocked the old man.    

The old man was also an alchemist. When he saw the true fire of the Underworld, his pupils contracted. With a trembling voice, he said, "What kind of flame is this? The flame carries a gloomy and cold aura. It's quite extraordinary!"    

Many fire-attributed cultivators were able to control flames.    

However, in order to become an alchemist, one's control over the flame was only a foundation.    

"Do you have the certification from the Elixir Alliance?" The old man's tone became much more polite.    

After all, even though he was an apothecary, he wasn't very knowledgeable when it came to being assigned as a guard.    

Lu Yu shook his head. He had never taken over the Pill Alliance before, so he naturally didn't have the approval of the Pill Alliance.    

This time, he made a mistake.    

The old man frowned. "We only accept alchemists from the Pill Alliance. You'd better go to the Elixir Alliance and get certified before coming back. "    

The certification of the Elixir Alliance was divided into Heaven, Earth, and Mysterious rank 3 apothecaries.    

Other than that, alchemists below the Xuan level are all mediocre. However, if they were to get certified by the Pill Alliance, they would also have a badge to prove their identity as an alchemist.    

A Mystic Rank alchemist was enough to run amok on any star. In many sects, they would be warmly welcomed.    

Because they had alchemists, it meant that this faction would have an endless supply of medicine, nurturing countless experts. This was an invisible wealth.    

"Is there no other way?"    

Lu Yu frowned. He was going to kill the Green Lotus God now, so he naturally couldn't waste his time on this matter.    

"I'm sorry, unless you can really show that you are an alchemist." The old man still refused.    

Although Lu Yu was able to use flames, many fire-attributed cultivators were able to do the same. However, they were still unable to confirm that Lu Yu was an alchemist.    

Lu Yu casually swept his eyes across the place and found a black medicine beside the old man's hand.    

The surface of the medicine was covered with black flaws. There was also a layer of black smoke coming out from it, making it hard for one's nose to breathe.    

Noticing Lu Yu's gaze, the old man faintly smiled, "This is a defective product that my apprentice has just refined. Are you interested in this thing?"    

Lu Yu glanced at the medicine and said, "Iron Sun Flower, Stone Pearl Sand. Cloud Emperor Fruit..."    

He listed out the ingredients needed to refine the medicine.    

The old man's expression immediately stiffened. This was indeed the ingredient that his apprentice had refined.    

The most important point was that the reason why the old man's apprentice failed in refining was because he had placed the ingredients wrongly.    

If it was because he recognized what this medicine was, then the ingredients that were revealed were nothing. But now, Lu Yu even mentioned the ingredients that his apprentice had put in too much.    

If not for his familiarity with medicinal theory and alchemy, he would absolutely not be able to do this.    

"Can you lend me the medicine for a while?" Lu Yu asked.    

The old man nodded in a daze.    

He knew very well that even if he encountered an unfamiliar medicine, he would definitely not be able to easily analyze all the ingredients within the medicine.
