Le Kai can only put his hope in the last stone house, hoping that there will be something to be gained.

The last stone house really did not disappoint Le Kai, just pushed the door open, there was a strong fragrance in the face, which was refreshing, and instantly forgot the pungent sulfur smell outside, as if in another world, its air was fresh, even more than the sky.

Happy and happy, looking at it, I couldn't help but smile.

This stone house, which was larger than the other two combined, had no treasure scattered all over the place, and no other strange things, just some strange plants. Here, it is shocking that it is a field of medicine. Some fruits or plants that Le Kai has never seen before, full of fragrance, fill the entire space.

And the stone gate didn't know what material it was made of, and when it was closed, there was not even half a breath leaking out, and the space here was like another world, completely isolated from radiation, and these fruits and plants grew extremely luxuriantly. When I take a breath, I feel refreshed, as if I have eaten an elixir.

Le Kai hurriedly closed the stone door to prevent the aura from leaking out.

The treasure of heaven and earth that the teacher said, it is estimated that it refers to these things, the last time I ate a "Three Yang Fruit", I directly produced true qi, and stepped into the ranks of martial artists, if I ate all the hundreds of fruits here, wouldn't it be directly to the level of top martial artists?

Le Kai was overjoyed, this medicine field, I don't know how many years it has been stored, presumably no one has picked it, so it grows extremely luxuriantly, so many fruits, all cheap themselves.

Le Kai is also a child's heart, seeing so many treasures, naturally want to collect them all, only in the watch space, is the safest.

Shen Nian probed into the watch, Le Kai took out all the jerky, and with the baby, who cares about those mundane things. But when the divine mind touched the blank jade slip that had just been put in, something wonderful happened. As soon as the jade Jianpu came into contact with Le Kai's divine sense, it was like a sleeping beast suddenly waking up, opening its mouth and swallowing it.

This sudden and unexpected, Le Kai didn't even react, he was directly inhaled, and suddenly felt that he had entered an extremely ethereal world.

The clouds and mist lingered, like a fairyland, the thick fog was obviously different from the dust shrouded in the basin outside, and a breath was as shocking as if eating a mouthful of sticky jam, making people have a strange feeling that their stomachs were filled. Although the incident was in a hurry, Le Kai's excellent psychological element made him not panic, but looked at his surroundings extremely calmly.

It is the first time that pure consciousness has entered such a strange place, and the feeling of using the space of the watch is completely different, and there is a sense of immersive realism. Naturally, this feeling of satiety in the stomach is just a spiritual feeling.

"I have a good heart, and I can take on a big responsibility. An ethereal, slow, old voice suddenly sounded. The clouds and mist in front of him slowly dispersed, revealing a beard with white hair, dressed in ancient costumes, and an outstanding old man like a fairy wind and bones, with deep eyes and flames, as if there were no eyes, more like two whirlpools, full of endless attraction, as long as one glance, it can make the mind sink into it and fall into the endless void.

Le Xingxing's head was shocked, and he desperately looked away, but he was already sweating profusely, and he was not afraid of the sky and the earth, and he was also full of fear at this moment.

"Who are you, and what is your purpose?"

Le Kai didn't ask why I'm talking nonsense here, but went straight to the point, he believed that although this old man was terrible, he didn't have to kill intent, so he didn't have to worry about his safety for the time being. As for the awe in the heart, it is because the strength of the old man is too terrifying, just like a human being facing a god, even if the god does not want to harm a human being, but the innate power still makes people fearful.

"Don't be afraid, this is just a trace of divine thought left by me, and my true body has long been destroyed. The reason why I save zài is to complete the task assigned by the subject. Little friend, you have a good heart, you have a deep vein, and you are born with fire attributes, which is exactly the talent that my Dan Dao needs. ”

The old man tried his best to restrain his might, but Rao was like this, and Le Kai still felt the endless pressure, if it weren't for him being far beyond ordinary people, he was afraid that he wouldn't even be able to speak.

"Dan Dao, is it alchemy?" Le Kai thought of the empty bottles outside, and suddenly said happily: "Just like those Taoist priests in Xianxia novels, refining the elixir, can you become an immortal by eating one pill?"

Rao is old man is like a fairy, and he couldn't help but laugh dumbly when he heard the words, and said, "How can it be so easy." The so-called Dan Dao is to enter the Dao with Dan and achieve supreme supernatural powers. From the beginning of heaven and earth, people with the wisdom and spirituality have realized the way of heaven and discovered themselves, in order to be able to communicate with heaven and earth, and pursue the way of heaven that is immortal. Those who have great wisdom create the art of cultivation, exercise their own body, transcend life and death, and attain the Tao, which is called internal cultivation. Dan Dao, on the other hand, is assisted by external objects, based on heaven and earth treasures, heaven and earth aura, and integrated into one, which is for Dan. Dan, a combination of heaven and earth, has the miraculous effect of turning things around. This is Waidan. ”

Seeing that Le Kai was confused, the old man said again: "Let's put it this way! Cultivation is all for the sake of 'Dan', but ordinary cultivators use their own bodies as the Dan furnace to breathe and breathe, and finally form 'Dan' in the Dantian, which is the foundation of a cultivator. This kind of cultivation method, one requires a suitable physique to communicate with heaven and earth, and the other requires subtle exercises. But Dan Dao is different, at the beginning of the use of the essence of the Dan furnace, with the elixir as the main, supplemented by the aura of heaven and earth, directly condensed into 'Dan', although this Dan and the human body condensed by itself Dan is not the same, but the nature is similar, more importantly, the speed is countless times faster. Taking the pill can also have the same cultivation effect. The so-called Dan Dao is a shortcut to cultivation. ”

Le Kai seemed to realize and said: "Isn't this the Taoist alchemy, what's the difference? If the elixir is enough, wouldn't the cultivation go up with a swish?"

The old man said: "Strictly speaking, there is no difference. It's just that although the way of alchemy is a shortcut, the requirements for the body are extremely high, and not everyone can learn it. In the tens of thousands of years in my Chinese land, there are only a few people who have attained the essence, and when it comes to my generation, I can't even find a qualified apprentice. ”

The old man sighed gloomily: "The way of heaven is changing, mysterious and unpredictable, there has never been a person with suitable qualifications for hundreds of years, I know that in this life, I want to fulfill the last wish of my ancestors, I am afraid that I can't, fortunately, I finally met you, boy, we are destined." ”
