Listening to the majestic general once again released a crisp and pleasant song, the fire was flying into the sky, squinting his eyes, and his wrinkled old face also burst into a smile.

"Yes, you're really good at medical skills. What can I do for you?"

Seeing the expression of Huo chongtian, Fangyuan was overjoyed. He quickly took out the phagocytic crystal stone, handed it to Huo chongtian and said, "I want to strengthen the elder to refine this phagocytic crystal into weapons!"

"Devour the crystal stone!" The fire flushed into the sky and looked surprised. He murmured to himself, "it's been a long time since such materials have appeared, but you have some luck."

"Master, you are so praised. When can we start refining?" Chen Fan humbly arched his hand, followed by words.

But who knows the fire soared into the sky, but he waved his hand and sat on the ground with such a big stab: "don't worry, you boy. It's not so easy to refine and devour the crystal stone. It's not easy to find any auxiliary materials needed."

"Let's make it clear to our predecessors!"

Hearing this, chen fan immediately showed an open-minded look for advice.

In fact, he had been prepared for this before his arrival. After all, the material of swallowing crystal is not ordinary, so it can't be refined at will like other weapons.

In that case, he doesn't have to make a special trip here to look for fire.

"Don't worry. I'll ask you what kind of weapon you want to refine. Is it strong and strong but weak in strength, or weak in strength, but has great potential for development?"

Huo chongtian finally recovered to the demeanor of the master, but he still held the cricket jar in his hand.

Chen Fan pondered for a moment, then said in a deep voice: "what I want is a powerful weapon with great potential for development, which is the strongest weapon in Xuanguo! I wonder if you can refine it

"Hey, you're a slippery guy. You've even used a lot of encouragement to me. Well, I just like your personality. I can refine what you want, but I still lack some materials. You may find them? "

Chen fan was surprised when he heard that the fire was so easy. He thought that the old man had to put on a good demeanor. What kind of test would he set up.

He didn't know that he only loved two things in his life.

One is fighting crickets, and the second is refining utensils.

He always itches when he sees some rare materials for refining utensils. Although he pretends to be indifferent now, he is more anxious than anyone else.

Even after hearing chen fan asked what materials he needed, he immediately opened his mouth and said three things: "Qingming rootless water, skeleton Python venom, and most importantly, Diyan hundred alchemy!"

Chen Fan frowned a little.

Because of these materials, he only knew two kinds: Qingming rootless water and skeleton Python venom.

Chen fan had never even heard of it.

"I dare to ask you, elder, where to find Diyan hundred alchemy and what kind of form is it?"

Fire into the sky naturally know that Chen fan does not understand, also does not hide, patiently answers for him.

Deep underground, there is often magma agitation, and around the magma, it is easy to have associated ore. this kind of associated ore, because it has been roasted at high temperature all the year round, is equivalent to being tempered all the time. Its texture is extremely tough. It is the best material for making weapons.

And this kind of ore in the center of the earth changes once every year. The texture is stronger and the color is deeper.

The so-called hundred smelting gold means that this kind of ore must exist in the earth's core for a hundred years before reaching the standard.
