Just when Fang Kun was secretly surprised, a trace of sparks had already emerged from the hole under the huge Dan furnace, and with the extension of time, it was constantly flourishing, and finally turned into flames.

Fang Kun couldn't help but sigh again, the descendants of the Shennong clan were indeed not simple, not only had they found such a hidden space, but they had also discovered the fire in the center of the earth here, if it was him, even if he had divine sense, he might not be able to find it!

Just when Fang Kun was still secretly sighing, Jiang Xiong suddenly spoke.

"Brother Fang, according to what you just meant, do you want to move this Dan furnace away?" Jiang Xiong asked suspiciously.

Fang Kun, who was immersed in the surprise, realized that he was so happy that he forgot the most important things, and hurriedly said: "Yes, I'll do this, and also, turn off this fire in the center of the earth first, and then open it again after the arrangement is completed!"

Fang Kun said excitedly and incoherently, after speaking, he walked directly to the Dan furnace and began to observe carefully.

This Dan furnace is more than one meter high, but fortunately, it is not a stove built like Fu Yuan below, but four stone platforms fixed on the ground, and the huge Dan furnace sits firmly on it.

After Jiang Xiong turned off the flame mechanism, Fang Ku did not hesitate, and used the wooden sword in his hand to cut off the four steel ropes that held the Dan furnace in place, and then picked up the huge Dan furnace and put it aside.

When Jiang Xiong saw the power of the Thunder God Sword again, although he was prepared, he still felt a sense of fear, especially when he felt the slightest electric power from the sword body at close range, he felt that his divine soul trembled a little, but fortunately, the lightning was gone in an instant!

Seeing Jiang Xiong's expression, Fang Kun shook his head a little helplessly, then turned around and walked outside, Jiang Xiong hurriedly reacted and followed.

Fang Kun went straight to the three elixirs, while Jiang Xiong walked to the stone platform, but he didn't take the treasure tripod directly, but lit the incense candles placed on the stone platform, and then retreated to the stone platform, knelt on the ground, and whispered for a while before he began to kneel down reverently.

After nine bows, Jiang Xiong looked at the Baoding on the stone platform in a daze, and it was not until Fang Kun finished collecting the last treasure medicine that Jiang Xiong moved, only to see him grit his teeth, walk onto the stone platform, slowly walk to the Baoding, bow down, and then pick up the Baoding.

Although this Baoding is much smaller than the boiler inside, it is obviously not light, because when Jiang Xiong picked it up, his body could not stand upright, and he was trembling slightly, which was obviously very difficult.

Fortunately, when he walked down the stone platform with Baoding in his arms, Fang Kun had already put the elixir into the alchemy room, walked out again, and took Baoding directly from him.

Seeing Fang Kun easily carrying Baoding into the alchemy room, Jiang Xiong's face showed a helpless wry smile, although he was able to pick up this Baoding, which weighed more than a thousand catties, it was also the first time he tried, he really didn't expect that Fang Kun would hold it so easily.

"Brother Fang, do you need to make any other preparations?"

After walking into the alchemy room with a wry smile, Jiang Xiong looked at Fang Kun who was placing the Dan furnace and asked.

"No need!" Fang Kun didn't look back, and said directly.

Jiang Xiong's face showed a hint of hesitation, he naturally wanted to stay here and watch Fang Kun's alchemy, after all, this was a rare opportunity, and Fang Kun had promised before, but when it came to this time, he was a little embarrassed, as an inherited alchemy family, he knew very well that when the alchemist was alchemy, he needed to concentrate wholeheartedly, and if he was disturbed a little, he might fall short!

Fortunately, Fang Kun seemed to sense his mentality, and said directly: "Brother Jiang, the stone gate should be closed, otherwise it will affect those treasure medicines outside, and besides, please put those foods together, it is best to stay away from the Dan furnace, otherwise once there is an accident, your hard work will be in vain!"

After Fang Kun finished speaking, he smiled at Jiang Xiong, then ignored it, sat in front of the Dan furnace, and slowly opened the mechanism below.

Jiang Xiong showed a helpless wry smile again, then turned around and closed the stone door, and then began to put the food in place according to what Fang Kun said.

Fang Kun's face gradually became a little solemn, staring at the hole under the Dan furnace. As the black slate slowly opened, the hot breath quickly escaped, and a few minutes later, a spark appeared, obviously, it would take some time for the fire to fully extend, and he just used this time to start studying the control mechanism.

Obviously, with the extension of time, the fire in the center of the earth will become stronger and stronger, and he must always keep the flame in the Dan furnace in the best state in order to successfully refine the Pei Yuan Dan, however, these are not difficult things for him who has divine sense, what worries him the most is that after he really starts alchemy, can he persist in the consumption of his true qi and divine consciousness until the end, as long as there are no problems in this aspect, he will have full confidence and succeed at one time.

After pondering for a while, Fang Kun untied the top cover, then turned around and picked up an elixir, then closed his eyes and began to quietly comprehend.

It took nearly an hour for Jiang Xiong to put all the food in a corner of the cave, away from the Dan furnace, after being busy, he hesitated, and walked directly to Fang Kun's side not far away, two or three meters away from the Dan furnace, seeing Fang Kun holding a magic medicine in his hand, his eyes were closed, as if he was cultivating, and as if he was contemplating something, he couldn't help but be a little curious, and even more full of doubts, for example, why did Fang Kun let the Dan furnace burn empty, and there was no movement for a long time, but he didn't bother, but sat cross-legged on the ground, quietly waiting for Fang Kun to start alchemy。

However, he waited for more than four hours, fortunately, he had enough patience, although he had many doubts in his heart, but he did not bother Fang Kun, in the process, Fang Kun kept picking up every magic medicine or treasure medicine, each time it was almost half an hour, until the afternoon, Fang Kun stopped and opened his eyes.

At this time, the fire in the center of the earth had already entered the Dan furnace along the small hole under the Dan furnace, and it was burning vigorously, and the alchemy room was very hot.

Fang Kun put down the treasure medicine in his hand, took out a jade bottle and put it beside him, and then began to move the mechanism next to him, and with that, the flames in the Dan furnace began to gradually weaken.

It's not that Fang Kun thinks the fire is too strong, on the contrary, he still thinks that these Earth-centered Fires are too weak in his heart, after all, this Earth-Heart Fire, although it is much stronger than ordinary flames, is also much stronger than the fire he used in alchemy before, but because it has not formed a real fire, therefore, it can't be regarded as a different fire, and it is too much worse than the Golden Crow Fire he had in his previous life.

And the reason why he wants to do this is because the flame in the Dan furnace, although it is very vigorous, but when the fire in the center of the earth reaches its strongest, it does not need so many flames, which is like a car that can only run two hundred yards, when its speed reaches the limit, even if you step on the accelerator hard and consume more fuel, his speed will not be able to improve, the reason is the same!

At this time, Jiang Xiong was attracted all his attention by the jade bottle beside Fang Kun, he naturally saw at a glance that the six pills in the jade bottle were the Xiao Peiyuan Pill he had taken before, watching Fang Kun take out six pills at a time, saying that he was not shocked, it was definitely a lie!

On the other side, after feeling that the flame in the Dan furnace had reached the best state, Fang Kun closed the furnace lid, and after waiting for more than ten minutes, he opened the already hot furnace lid, and with a casual wave of his other hand, a wisp of black smoke flew out from the flamed Dan furnace!

After that, without waiting for Jiang Xiong to react, Fang Kun quickly put a treasure medicine beside him into the Dan furnace, and then directly closed the lid of the furnace.

Seeing the scene where Fang Ku threw the treasure medicine into the Dan furnace, Jiang Xiong almost screamed, but fortunately he covered his mouth in time. In his opinion, Fang Kun threw the treasure medicine directly into the flames like this, it was definitely a waste, because, when the flame in the furnace was so strong, the treasure medicine was not instantly burned into ashes?

However, the moment Fang Kun closed the lid on the furnace, his eyes widened, as if he had seen a ghost.
