This Qinghuo Dan furnace is a little special, the flames in the Dan furnace are rolling, and the vent outside the Dan furnace is still cool.

After the flame martial soul ignited the flint in the alchemy furnace, it merged with the flames in the alchemy furnace.

Ye Kong didn't feel the scorching, but instead had a warm feeling, as if the flame in the Dan furnace was an extension of his flame martial spirit, and he could control the changes in the flame in the Dan furnace with his mind.

Ye Kong sensed it carefully and found that the flame in the alchemy furnace needed not only the flame martial spirit, but also the assistance of true qi.

The Flame Soul can better communicate with the flames, but when controlling the flames, it still needs True Qi to maintain it.

"Whew!"

Suddenly, the flames in the alchemy furnace surged, bursting out of the hole in the lid of the alchemy furnace.

Ye Kong's heart was shocked, and he quickly collected his thoughts, suppressed the flames in the alchemy furnace again, and silently used the Blood Flame Red Lotus Gong, trying to communicate with the flames in the alchemy furnace to control the changes in the flames in the alchemy furnace.

Before refining and purifying medicinal herbs, you must first learn to control the flames.

Ye Kong used the Blood Flame Red Lotus Gong to control the flames in the alchemy furnace to roll, sometimes blazing and fierce, sometimes warm and soft, and his mastery of the flames in the alchemy furnace became more and more exquisite.

Under Ye Kong's control, the flames in the alchemy furnace began to rotate and stretch slowly, pulling out a very fine fiery thread from the flames, and began to circle around the alchemy furnace, forming a spiral, from top to bottom, without intersecting each other.

Soon, the entire alchemy furnace was filled with a spiral of red fire wires, and then, the flames in the alchemy furnace fused back together, forming a small fiery red alchemy furnace in the alchemy furnace, and the flames in it tumbled as if they were real.

Next, the flames in the furnace sometimes turn into flowers, sometimes into branches and leaves, sometimes into mountains, sometimes into rivers and seas.

In the midst of constant transformation, Ye Kong's grasp of flames became more and more flexible.

Ye Kong felt that the time was almost up, and reached out and threw a withered leaf vine into the alchemy furnace. The flames in the alchemy furnace tumbled, engulfing the withered leaf vines in an instant, and burning to ashes in the blink of an eye.

Ye Kong shook his head secretly, in terms of flame control, he believed that there would be no problem, but he still didn't understand the heat required by the withered leaf vine.

If you want to master the heat required for each medicinal herb, you must go through many practices. Of course, the stronger the person who controls the flame, the faster the fire will be able to master the heat required for each medicinal material.

Ye Kong took out the ashes of the medicinal herb from the vent, took out a withered leaf vine again, and threw it into the alchemy furnace.

Ye Kong turned the temperature of the flame to the lowest and wrapped the dead leaf vine, the flame rolled, and the outer skin of the dead leaf vine gradually dried up.

Unfortunately, just as the outer skin of the withered vine became more and more dry, the outer skin of the withered vine fell off, and the green inside turned to ashes again as soon as it was revealed.

It is recorded in the ancient books of the Alchemy Pavilion that the owner of the Flame Martial Soul, when he first purifies the medicinal materials, generally has to waste dozens of medicinal materials in order to gradually find out the heat required for the medicinal materials, and Ye Kong is not discouraged.

Ye Kong took a deep breath, took out a withered leaf vine again, and threw it into the alchemy furnace. A moment later, the withered vine also turned to ashes.

Ye Kong recalled in his mind the alchemy experiences he had seen, and compared with the few dead leaf vines he had refined, Ye Kong's eyes showed a sudden look.

It turns out that if you want to refine the essence of the medicinal herbs intact, you need to constantly change the temperature of the flame with the refining process of the medicinal herbs.

Thinking of this, Ye Kong took out a withered leaf vine again and threw it into the alchemy furnace, the flames rolled, and swallowed the withered leaf vine again.

After consuming seven withered leaf vines in a row, Ye Kong finally knew the heat of each time period of the withered leaf vine purification, and threw a withered leaf vine into the alchemy furnace again.

The withered leaf vine floated in the flames, and soon became yellow, and the leaves controlled the temperature of the flames, and the outer skin of the withered leaf vine quickly dissolved, revealing the green juice inside.

Ye Kong didn't dare to be careless, and quickly transformed the flame in the alchemy furnace into a small fire, and the temperature dropped rapidly, maintaining the flame in the alchemy furnace at a very low temperature, and gradually burning the dead leaf vine into a green and viscous juice.

Over time, a black cloud of impurities began to emerge from the green juice. According to the Danfang record, Ye Kong's technique changed slightly, and he separated a wisp of flame martial soul power, bringing out the black impurities from the vent.

This is not the end of purification, Ye Kong continued to maintain the temperature of the flame, and several black impurities appeared in the green juice, all of which were separated by Ye Kong.

After a quarter of an hour, no more impurities appeared in the green juice, and its volume was reduced by half, exuding a misty glow, filled with a faint fragrance.

Ye Kong's hands shook slightly, and the lid of the alchemy furnace was opened by a wave of heat, and green juice quickly rushed out of the alchemy furnace.

Ye Kong had already prepared a jade bottle and quickly put this ball of green juice into it.

A satisfied smile appeared at the corner of Ye Kong's mouth, and he finally refined the essence of a medicinal material, which can be regarded as the first step on the road of alchemy. He believed that it wouldn't be long before he would become a true alchemist!

At this time, Ye Kongfang felt a very tired feeling, his whole body was sore, and he gasped for breath.

To purify the elixir, you need to use all your mind, and the consumption of spiritual power and true qi is very large.

Ye Kong put away the flame martial spirit, opened his mouth and threw a spirit pill into his mouth.

The medicinal power dispersed, and Ye Kong silently operated the Nine Turns to Return Yuan Gong, quickly refining the power of the Gathering Spirit Pill, and nourishing Ye Kong's limbs and hundreds of remains.

The Gathering Spirit Pill, which contains the majestic aura of heaven and earth, is very easy to be absorbed by the human body and can greatly speed up the speed of cultivation. Similarly, after the consumption of true qi, taking the Gathering Spirit Pill can also quickly restore the true qi in the body.

Cultivating after the True Qi is exhausted can make the replenished True Qi more condensed and refined, and even the power of the martial soul can be enhanced.

Half an hour later, Ye Kong opened his eyes, and his cultivation was completely restored, and he faintly strengthened a little.

Of course, most of the power of the Gathering Spirit Pill was dormant in Ye Kong's body, and it had not yet been absorbed by him. When he cultivates again in the future, he will slowly be refined and absorbed by him.

With the successful experience of purifying the dead leaf vine this time, Ye Kong successfully purified the remaining dead leaf vine successively.

Ye Kong had a complete grasp of the heat required by the withered leaf vine, and he didn't know if it was because of the Chaos Qinglian Martial Soul, when he purified the withered leaf vine, a qiē reaction in the alchemy furnace appeared in the bottom of his heart in detail, allowing him to quickly make an appropriate response. Of the remaining dead leaf vines, Ye Kong only refined and scrapped three or four plants, and all the rest were successfully purified.

Ye Kong's gaze fell on the Blood Spot Grass, and he threw the Blood Spot Grass into the alchemy furnace and continued to start refining the medicinal herbs.
