In a mysterious space, a red-hot crucible was quietly locked in a sea of fire.

In the pill furnace, Chen Feng was bitterly looking around at the increasing number of Spiritual Lights in his surroundings.

"Heavens, are you playing with me?" Chen Feng smiled bitterly as he protected every inch of his body with all his Quintessential Essence.

After an unknown amount of time, the Golden Samadhi True Fire was no longer in the crucible. The only thing left inside was the crimson, bloody Soul Fire.

Just like a military formation that was being commanded, countless Earthly Flames simultaneously surged towards Chen Feng.

"Why are these flames so agile? It's as if they're controlled by an outsider." Chen Feng tried his best to use his Divine Earth Flame to protect his body as he said with surprise.

Two streams of Soul Fire collided around Chen Feng, causing it to be difficult to part with them. However, although the Earthcore Fire that Chen Feng could use was equally powerful, in terms of quantity, it was greatly inferior to the other portion of the pill furnace.

Not long after, Chen Feng felt a wave of exhaustion. Most of the Soul Fire in his body had already been used up.

The other stream of Spiritual Flames seemed to know of Chen Feng's situation. It was like a ferocious tiger descending the mountain as it swarmed forward and fiercely surrounded Chen Feng.

Immediately, a heart-wrenching pain assaulted Chen Feng's heart. In an instant, Chen Feng's sweat fell like rain, but it was quickly evaporated by the scorching temperature.

"Roar! If you give up, you're dead. That's why, I can't give up!" Chen Feng growled in a low voice as his body flashed with golden light. He abruptly activated the "Profound Mysterious Dragon Yellow Scripture" and his pure zhenqi painfully supported the invasion of the Earth Spirit Fire.

However, the Earth's Soul Fire was extremely powerful. Even though Chen Feng's Quintessential Essence had far surpassed the peak late stage of the False Core Stage, it was still unable to sustain him for too long. Time passed minute by minute, second by second. Chen Feng's face became increasingly pale. The golden light that appeared outside his body also gradually dimmed.

"Looks like I'm really going to die here today. All my life, I have been concocting pills, but I never thought that in the end, I would be treated as a pill refiner. " Chen Feng looked bitterly at the Earth Spiritual Flame that was getting fiercer and fiercer as he said helplessly.

Right after he said that, Chen Feng exclaimed in his mind, "Why didn't I think of it? Right now, I'm like a pill that has yet to be concocted."

"In the eyes of a powerful alchemist, a strong flame isn't used to flash a light.

"Pill forging? "For example, pill forging?" Chen Feng suddenly destroyed the pill. The more powerful the flame, the purer the pill would be. "

"Then, I'll transform into a pill and take the initiative to complement your tempering."

"Try to understand how you control the fire and observe every detail of your pill refinement."

"I don't believe that you could deliberately refine me to death!"

With this thought, the protection around Chen Feng quietly disappeared. At this moment, not only did Chen Feng no longer resist the corrosion of the Spirit Fire, he even actively cooperated with it.

"Hahaha, children are worth teaching. I never would have thought that this kid would have actually comprehended this principle at the very last moment. " In the void above the sea of fire outside, one eye was staring at the pill furnace with a look of admiration.

"In that case, I'll help you again." As he spoke, his eyes suddenly shot out a beam of red light, which sprinkled on the pill furnace.

"Rumble …"

Following a slight tremble, the flame within the pill furnace transformed once again. The originally berserk Spiritual Flames suddenly became quiet. The expression in their eyes also gradually became faint, turning into a faint orange color.

"Sky Spirit Orange Flame?" There was neither joy nor sadness in Chen Feng's heart. When he saw the appearance of the orange flame, he was only surprised for a moment before he started rolling back and forth along the flame.

At this moment, it was as if Chen Feng was no longer alone. He was only an incomplete pill, waiting for the apothecaries to temper and polish him.

At the same time, Chen Feng's mind was opened. He concentrated on observing the way the flames were flowing around him, and at the same time, he also sensed the undulations from the unknown laws.

Gradually, Chen Feng was completely immersed in the comprehension of the flames. The little by little changes in the furnace were all exceptionally mysterious to him, causing him to feel extremely satisfied. Unknowingly, Chen Feng's previous cultivation stage, which could not be improved in any way, was gradually increasing.

Even more miraculous was that Chen Feng's body also became more solid under the tempering of the "Sky Spirit Orange Flame". The blood-red Earth Core Fire Source Spirit inside his body also gradually turned pale and turned orange.

"Looks like this kid's pill cultivating talent is not any weaker than mine." This way, I can be at ease and hand over my legacy to him to inherit. " In the middle of the air, that old voice sounded a little relieved.

After that, there was an endless silence.

Time slowly passed. Chen Feng was still in the pill furnace, rotating in waves of flames. His slightly opened eyes revealed a deep sense of comprehension.

After an unknown period of time, the orange flames gradually extinguished and the interior of the pill furnace became dark once more. As for Chen Feng, he sat cross-legged at the bottom of the pill furnace without making a sound, not moving at all.

At this moment, Chen Feng had sunk into a deep state of comprehension. Transforming into a pill had allowed Chen Feng to experience the true meaning of refining pills once. His comprehension of the Dao of alchemy had deepened by a lot. Especially because of the flame's trajectory in the furnace, Chen Feng's fire control skill had improved by a whole level.

Right now, he needed to fully integrate the insights he had just gained.

… ….

From the secret realm, two figures could be seen rushing out of a tunnel. Their clothes were tattered and their bodies were covered in numerous scars.

"Kuang Mang, what should we do?" One of them called out to the other.

If Chen Feng were to continue like this, he would definitely be able to recognize these two to be Wen Ya and Kuang Mang, the top ten experts of the Dragon Group's Elite Hall. This time when they entered the mystic realm, the two of them shared a secret realm jade key and entered.

"Wen Ya, quickly leave. I'll cover your retreat!" Mad and low, he said, "I didn't expect that Joyful Union Sect's beasts would actually sneak attack us. Quickly run and join up with the others, I'll hold them back!"

His wild face was filled with determination, as if he was ready to die at any moment.

"Kuang Mang, if that's the case, you will definitely die!" Warm Cliff was loyal. Seeing Mang Mang acting in such a manner, he was even more unwilling to leave.

"Do you want us to die together?" Mang Mang shouted harshly: "One of us must come out and tell the others about Joyful Union Sect's scheme, or else all of us will die here."

"I'm already severely injured, so I can't escape. Let me stall them and buy you some time!" His tone was bold and decisive.

Wen Ya gritted his teeth and finally nodded resolutely. He looked deeply at Kuang Mang, and said with reluctance, "Kuang Mang, take care!" With that, Wen Ya began to flee towards the distant tunnel.

"Too late!" Suddenly, a cold shout was heard and Wen Ya's escape route was blocked.

"It's you?" Wen Ya looked at the person who had suddenly appeared and cried out angrily.
