The Earth Center Pill, one of the hundred kinds of Qi Dan that has been extinct in ancient times, needs to be tempered with the Earth Heart Fire for a hundred years to become a Dan, and the refining materials are all spiritual things that have been extinct long ago, and no one has ever successfully refined them since ancient times.

The spiritual resources required for a furnace of the Earth Heart Pill were not very rare in ancient times, and ordinary people could not afford it at all.

It is extremely difficult to refine the geocentric pill, but the effect is extremely against the sky, it can condense the soul and strengthen the spiritual power, and the legend has a certain possibility that people will have a psychedelic realm for fifty years, during which the understanding of various exercises and secret techniques has increased by more than ten times.

The tenfold comprehension ability is very terrifying, and it is unimaginable to increase the cultivation increase, it is a bit like a Yuan Infant Stage cultivator re-starting the cultivation of the Dan Period, it is completely unhindered!

The effect of the Earth Heart Pill is not much worse than the Root Supplement Pill that repairs the spiritual root qualification.

And now Zhuang Yun actually said that the Dixin Pill is just an imitation of another pill, which is too unbelievable, the Dixin Pill has such an effect, so what kind of effect should the genuine Tianxin Dan have!

"There is a certain possibility that the Earth Heart Pill will make the monk have a big dream psychedelic realm, but the real trigger probability is less than one layer, but the genuine Tianxin Pill is completely different, as long as you take it, you are ten out of ten sure that it will trigger the psychedelic realm, and the time limit has also been extended to one hundred and fifty years!" Zhuang Yun explained slowly, and then said in a tone full of temptation: " Senior Zhu should know what the tenfold comprehension ability is equivalent to, as long as he has this ability, there is almost no obstacle when cultivating the exercises, this is a lot of time left, I think that with this time, coupled with the technique of planting babies, the possibility of the seniors getting married to a baby will be greatly increased!"

Han Ming was silent, if he could trigger the psychedelic realm, it would indeed be of great help to the baby, he could completely use the time of the comprehension exercises to cultivate mana, and it was also very possible to reduce the cultivation progress by half, that is to say, once he took the Tianxin Pill, then he would practice for one hundred and fifty years, which would be equivalent to three hundred years of cultivation under normal circumstances, and it would not be too far away to hit the Yuan Infant Stage in his lifetime!

If the Tianxin Pill really exists, it really can't be let go!

"The Tianxin Pill you said is all one-sided, how can you make me believe that you can't just rely on some of your words to let me go to the secret realm area!" Han Ming said solemnly.

When Zhuang Yun saw Han Ming's appearance, the corners of her mouth loosened slightly, and her heart was moved, she was afraid that Han Ming would look calm, so she refused Mingyan again.

"To tell the truth, in fact, whether there is Tianxin Pill in that secret realm, the younger generation doesn't know, but they just know that there is a Dan furnace connected to the underground essence fire, and there is a furnace of Dan medicine in it, and there is a Dan book on the stone table next to the Dan furnace, which is the formula of Tianxin Pill!" Zhuang Yun explained, and at the same time raised his hand slightly, throwing out a jade slip and flying towards Han Ming.

"Senior Zhu, this is that Dan book, seniors can test it!"

Han Ming took the jade slip, his spiritual power probed into it, and after carefully probing it, he nodded with a small half pillar of incense.

This Zhuang Yun is not lying, this Danshu does record the formula of Tianxin Dan and the refining method, this Danshu is indeed an antiquity, and there is a trace of Dan dirt lingering around, which is formed by long-term immersion in Danxiang, and only an alchemy master like him can detect it.

This jade slip has indeed been kept warm for thousands of years in a kind of Qidan Dan incense.

"According to what you said, there may really be a furnace of Tianxin Pill in the Dan furnace, but now that so many years have passed, some magic weapons are rotten, and the Dan furnace clearly has Dan incense leaking, which proves that it has been damaged, even if there is an elixir in it, I am afraid it will have already turned into dust!" Han Ming shook his head, with some regret on his face.

When Zhuang Yun saw Han Ming's appearance, he was afraid that Han Ming would regret it, so he immediately added: "Senior Zhu, don't worry, that Dan furnace is a rare treasure, and it is not damaged, it is connected to the underground essence fire day and night, and the elixir in it is warmed day and night, and it will automatically open every hundred years, releasing the fire essence accumulated in pregnancy, and spewing it out with the danxiang, and it is still running!"

"Oh, there is such a thing!" Han Ming's eyes lit up slightly, but then he added, "How did you know about this matter, and you know it in such detail, can you tell me about it, so that I can rest assured and decide whether to agree to this condition to you!"

"Naturally, it's just a bit long, it may take a long time!" Zhuang Yun said.

Han Ming didn't speak, just raised his hand and motioned for Zhuang Yun to continue.

Zhuang Yun nodded, and told Han Ming all the secrets and dishes she had buried in her heart for decades.

It took two hours before Zhuang Yun explained the ins and outs of the matter.

It turned out that the source of everything started with Zhuang Yun's father, Zhuang Lingfeng, the city lord of Sanmen Town.

Although Zhuang Lingfeng was only the city lord of a small immortal cultivation city, his sphere of influence was not small, seven or eight small immortal cultivation towns around Sanmen Town were all under his jurisdiction, and in an accident, he got a stone tablet from his subordinates.

The origin of this stele is very peculiar, it is said that Zhuang Lingfeng's subordinate killed a mid-stage monk of the Jiedan, and the mid-stage monk seemed to have been hunted down by someone and suffered a very serious injury before ending up in that fate.

At first, Zhuang Lingfeng thought that he had obtained a strange treasure, but he found that the stele had no other effect except for being hard, until one day, he inadvertently released a trace of the soul imprint in the stele, so as to know the origin of the Underworld Continent and the news of the secret realm left by the battle between the two immortals.

Later, Zhuang Lingfeng inquired for more than ten years, and only then did he know the news that there was indeed a secret realm in the depths of the Underworld Plateau, and he also knew that the secret realm area was opened every fifty years.

Zhuang Lingfeng felt that this was an opportunity, so he took advantage of the opening of the secret realm area and entered it, and it really made him discover a secret realm, which was a dilapidated ancient palace with a furnace of pills and two volumes of classics, which were the Infant Cultivation Technique and the Tianxin Dan Book!

At the beginning, Zhuang Lingfeng was like taking the Dan furnace away, but he found that the Dan furnace was very special, it was connected to the underground essence fire, and it couldn't be moved or opened at all, and once the strengthening means were applied, it was very likely to be seriously injured by the backlash.

Zhuang Lingfeng carefully surveyed and came to the conclusion that the Dan Furnace would be opened once in a hundred years, and after hesitating, he chose to leave, preparing to come in the next time the secret realm area was opened.

Leaving the Underworld Bone Plateau, Zhuang Lingfeng was about to return to Sanmen Town, but he met four people on the way, all of whom were masters of the Jiedan, and when he saw him, he asked him to hand over the stone stele, and then they fought without saying a word.

Although Zhuang Lingfeng was at the peak of the late stage of the Jiedan, the four people on the opposite side were equally powerful, he blew himself up and killed one person with skull fire, and only escaped with his life, but he was also seriously injured and was cursed by an enemy.

Zhuang Lingfeng rushed to Sanmen Town, took Zhuang Yun away, and hid, but it didn't last long before he was scattered by the cursed soul.

Before he died, in order to save Zhuang Yun's life and not be chased by those monks in the Dan period, Zhuang Lingfeng used an ancient teleportation array discovered in the early years to send Zhuang Yun away from the western neighbor and come to the Eastern Desert, and informed her about the secret realm, and the art of planting babies and the Tianxin Dandan book were also given to her.

"Senior Zhu, the younger father's deduced a secret method to open the Dan Furnace in advance, but it can only be twenty years in advance, and the Dan Furnace will be opened in more than thirty years, and the secret realm will be opened in twenty-five years, it is our only chance!" Zhuang Yun bowed lightly to Han Ming.

"If there are more than two Tianxin Pills, it would be good for the seniors to divide one for the juniors, if there is only one, it would be given to the seniors, and the seniors would give a little compensation!" Zhuang Yun added. I want to talk about "The Second Immortal Fandao" with more like-minded people, pay attention to "excellent reading literature" on WeChat, talk about life, and find confidants~
