Hearing the mighty general release a crisp and sweet scream once again, Huo Chongtian narrowed his eyes, and his wrinkled old face burst into a smile.

"Yes, you guys are really superb in medical skills. Come on, come to see the old man, why?"

Seeing Huo Chongtian's expression, Fang Yuan was overjoyed, and hurriedly took out the Devouring Spar, and handed it to Huo Chongtian, "The junior wants to force the senior to refine the Devouring Spar into a weapon!"

"Swallowing spar!" Huo Chongtian muttered to himself with a look of surprise in his eyes: "It's been a long time since these materials have appeared, you guys have some luck."

"The predecessor is absurd, dare to ask when can we start refining?" Chen Fan humbled his hand, and the words followed.

But who knows that Huo Gaotian waved his hand and sat on the ground with such a big thorn, "Don’t worry, you kid, it’s not easy to refine the swallowing spar, and it’s not easy to find any auxiliary materials needed. ."

"Also strong, seniors expressly!"

Upon hearing this, Chen Fan immediately showed a humbly asking for advice.

In fact, he had already prepared for this before he arrived. After all, the refining material of the swallowing spar was not a common product, and naturally it could not be refined at will like other weapons.

If that's the case, he doesn't need to make a special trip here to find the fire soaring to the sky.

"Don't worry, let me ask you again, what kind of weapon do you want to refine, is it tyrannical and lack of stamina, or is tyrannical and slightly inferior, but has great development potential?"

Huo Chongtian finally returned to the grace that the master refiner should have, but he still held the cricket pot in his hand in love.

Chen Fan pondered for a moment, and then said in a deep voice: "What the younger generation wants is a weapon that is tyrannical and has great development potential, that is, the strongest soldier of the Profound Kingdom! I wonder if the senior can refine it?"

"Hey, you guy is a slippery head, and you actually used a radical approach to the old man. No matter, the old man just likes your personality, I can practice what you want, but there are still a few materials that are missing. Could you find it? "

When Chen Fan heard that the fire was so easy to agree to it, he was a little surprised. Originally, he thought that the old man would have to put on a superior demeanor, and what kind of test would he set.

How did he know that Huo Chongtian only loved two things in his life.

One is the fighting cricket, and the second one is naturally a refiner.

Every time he saw some rare refining materials, his hands would be itchy. Don't look at him now pretending to be calm, but he was more anxious than anyone else.

Even after hearing Chen Fan's question about what materials he needed, he immediately opened his mouth and said three things: "Clear water without roots, skeleton python venom, and most importantly, Di Yan Bai alchemy!"

Chen Fan frowned slightly at these three things.

Because of these materials, he only knew two, namely Qingming Rootless Water, and Skeleton Python Venom.

As for the alchemy of Yanbai, Chen Fan had never even heard of it.

"Dare to ask seniors, where can Diyanbai alchemy come from, and what kind of form does it look like?"

Huo Chongtian naturally knew that Chen Fan didn't understand and didn't hide himself, so he patiently answered him.

In the deep underground, there is often magma agitation, and around the magma, associated ores are prone to appear. This associated ores is subjected to high temperature roasting all the year round, which is equivalent to being tempered all the time. The texture is extremely tough, and it is the best material for building weapons. .

And this kind of ore in the center of the earth will change once every year, the texture is tougher, and the color is deeper.

The so-called hundred alchemy means that this kind of ore must exist in the earth's core for a hundred years to reach the target.
