The sunlight slanted, and in an instant, it was covered by a haze of darkness, and at this moment, somewhere in Xuanshi City, a strange scene formed outside a huge lake.

A pale gold, half-zhang high furnace is like a bronze cast, bringing great visual shock, and a young man wearing a purple and gold robe next to it, the extremely shocking expression makes people laugh.

"Wei Ding, what he has is not only the aspect of refining pills, if an alchemist really has Wei Ding, the Ding Spirit that is domesticated later will have the ability to defy the sky, this ability, even if it is me, I am afraid I have to avoid it head-on!" Shaking his head lightly, Ding Lao stroked his long beard lightly, and said with a light smile: "Okay, it's useless to talk more, when you really have the strength to touch such items, I'll tell you slowly!" Now, the refining of this fourth-order pill, the Blood Forbidden Pill, begins! ”

"Hmm!" Nodding thoughtfully, Fang Chen instantly put out all the medicinal materials purchased in the medicinal herb trading one by one!

The figure slowly floated next to the medicine ding, Ding Lao's fingers moved slightly, and suddenly a cluster of small, but extremely high temperature blazing pale golden flames appeared in Ding Lao's hands, the palm sank slightly, and the flame was released from the fire port of the Ding furnace, and when it passed through its fire port into the inside of the Ding furnace, the original small cluster of flames instantly became vigorous and fierce, and when the flame was about to overflow the Ding furnace because of the surging, a faint red film quietly emerged in the Ding, and the flames were about to be kept in captivity.

Listening to the constant 'buzzing' sound in the Ding Furnace, Fang Chen only felt a sudden dizziness in his head, whether it was the flame and the crystal nucleus brown flame he used in the medicine hall, or this pale golden mysterious tripod and the Xuan-rank low-grade medicine tripod used in the medicine hall, they were all dozens of times stronger, or even worse.

With one mind and one mind, Fang Chen stared intently at the refining of the Ding Lao in front of him, after all, this kind of observation was much stronger than refining at will for a while, looking for a way.

Seeing the very vigorous flame in the Ding furnace, Ding Lao nodded with a smile, showing that he was very satisfied with this flame, and immediately went to the side of a purple gold double dragon fruit and put it into the Ding.

When the flames of "Boom ......" rushed inside, the originally bright and appetizing fruit quickly dissolved on the fire film in the Ding furnace like tofu dregs, and in less than a moment, it was completely transformed into a pool of bright red liquid.

It seemed that he liked the process of refining medicine very much, and a faint smile gradually appeared on Ding Lao's old face. With a slight movement of his fingers, the elf-like flames, as if they were extremely spiritual, immediately swept out towards the fire film with the most fierce fire, and the red liquid that was originally enough to cover the palm of his hand quickly evaporated, gradually shrinking at a speed visible to the naked eye.

The relief of removing impurities was boring, and when Fang Chen saw that he was about to fall asleep, the liquid formed by the original Purple Gold Double Dragon Fruit suddenly shrank several times, and it became a puddle of liquid only the size of a thumb, but at this moment, it was already extremely viscous, and I am afraid that compared with the unique viscose on the mainland, it was not much better.

After removing the impurities of the Zijin Shuanglong fruit, Ding Lao began to remove the impurities of other medicinal materials, the steps seem to be a little cumbersome, after removing all the impurities of the nitrogen flower, black jade red crystal nucleus, Xuanzhu grass and other medicinal materials, the sky has been completely dark, the sky is full of dark clouds, obviously, tomorrow's weather, will not be much better.

After that, it is purification, but this extremely important step seems to be extremely easy for Ding Lao, this time the former did not deposit a variety of medicinal materials in batches, but put them all in the Ding furnace, and carried out unified refining and storage.

This was quite an easy thing for Ding Lao, but for Fang Chen, who was extremely cumbersome and important to purify the step, it really made the latter a little embarrassed.

More than a dozen kinds of medicinal liquids that were melted into liquids due to the removal of impurities from medicinal materials were each circled in a unique place on top of the fire film for separate purification, and perhaps because the spiritual consciousness required for purification was too huge, and Ding Lao's current soul body state could not last too long, Ding Lao's originally relaxed expression gradually solidified, and was replaced by a dense fine bead of sweat on his forehead.

All kinds of viscous liquids gradually solidified, and then formed small crystals, and under the blazing pale golden flames, all the medicinal materials had no power to resist, and their necks were waiting to be killed.

"Whew!" After more than an hour, the originally cold Ding Lao instantly lost a long breath, and the liquid of medicinal materials on the fire film in his Ding furnace also turned into a fine pure color powder, obviously, the crucial step of purification was completed.

After picking up several jade bottles from the white ring and filling them separately, Ding Lao took advantage of the gap to glance at Fang Chen beside him, and when he found that the latter's face was full of surprise at the moment, Ding Lao's originally somewhat pale face suddenly appeared a smug smile.

"Ahem, next, Cheng Dan begins!" Turning around, looking at the tiny dragon that was constantly floating on the pale golden Ding furnace, the corners of Ding Lao's mouth rose and fell slightly, but it was a huge guarantee for the probability of Cheng Dan.

And as Ding Lao's voice sounded, Fang Chen next to him suddenly swallowed a mouthful of saliva with a dry throat, and immediately stared at the pale golden Ding furnace in front of him intently again.

As the sound fell, the flame in Ding Lao's hand rose sharply again, so that the fire film in the Ding furnace suddenly sounded a 'buzzing' trembling sound, as if the fire had arrived, Ding Lao's eyes instantly narrowed slightly, and his hands picked up the purification powder on the side, and then put it into the Ding furnace.

"Puff ......" The flames in the Ding furnace are like a dragon crossing the river, when the powder is just placed on the fire film, the powder instantly becomes a little scorched, and Ding Lao's eyes are also suddenly open at this moment, his forehead is covered with a little sweat, and his fingers are constantly moving, controlling this unruly flame.

With the blessing of the flames, when Ding Lao combined more than ten kinds of medicinal powders into one, his flabby left hand picked up a white jade bottle from the ring, and without the slightest hesitation, the former quickly opened it, and poured out a green liquid inside the bottle into the Ding furnace, which was constantly becoming a little blackened powder.

......With the submersion of the green liquid, the originally dry medicinal powder quickly emitted bursts of white smoke as if the scorching sand in the desert met a water source.

"This kind of alchemy, as well as spiritual sense, is it too terrifying!" He rolled his eyes incredulously, and the corners of Fang Chen's mouth twitched slightly from being too shocked.

At this moment, Ding Lao's impermeable spiritual sense diffusion, and his extremely proficient refining technique was Fang Chen's father, and Fang Yan, who was a great pharmacist, was probably less than one ten-thousandth of the former, so it was no wonder that Fang Chen was so shocked.

Just as Fang Chen was thinking, a strange fragrance suddenly came to his nose, and it immediately spread in all directions, obviously, this was a sign of Cheng Dan.

In Fang Chen's eyes, when he forgot about the Ding Furnace through the gradually dissipating white mist, a dark red pill was also slowly forming in the Ding Furnace.

"Roaring ......" abruptly, a low dragon roar sound came out of the Ding furnace, making an extremely joyful sound.

"Haha...... This Blood Forbidden Pill can be regarded as a refining completion! In less than a moment, at the same time as Fang Chen smacked his tongue slightly, an extremely shocked old voice suddenly made Fang Chen's eyes suddenly burst out, and the corners of his mouth twitched extremely violently.
