After Du did not forget to jump into this mist-shrouded cliff, as expected, half a foot deep was a boulder platform protruding outward.

After standing firmly on the platform, Du Bu looked in the direction of the platform and found that there seemed to be a deep cave inside.

When he was about to enter the cave, he suddenly felt that a woman in a long skirt on his head also fell from the cliff, Du did not forget to quickly turn around and hug her, naturally this person was Duan Sisi.

Duan Sisi originally closed his eyes and thought that he would fall off the cliff and break his bones, but he didn't expect to suddenly feel that he was in the fall, and he was hugged all of a sudden, and when he opened his eyes, he immediately said excitedly:

"Brother Du, it turns out that you are not dead, we are all still alive?"

Du didn't forget to put Duan Sisi down, and looked at her with an incredible expression at this time:

"Since Uncle Shao let us jump down, how could he harm us?"

Duan Sisi suddenly walked over and hugged Du Yi tightly:

"Even that dead old man still has a little conscience, Brother Du, do you know how scared I was at the moment after jumping off the cliff just now?"

I don't know when Shao Yuanying also stood beside the two of them, and said with a smile:

"This dead girl doesn't know how to be ashamed, she actually kissed me with your brother Du in front of me?"

As soon as Duan Sisi heard this voice, he immediately let go of Du Buzhi, turned around and saw that Shao Yuanying was looking at himself and Du Bucheng with a smile, so he said:

"Okay, you bad old man, you still have the face to jump down with us, you see I don't break your old legs. ”

After speaking, he picked up a branch under his feet and hit Shao Yuanying.

Du Zhifu was also a little angry:

"If you like to make trouble, I will ignore you!"

After saying that, he walked to the cave alone.

Duan Sisi saw that Du did not forget to enter the cave, and after dropping the branches, he said to Shao Yuanying:

"Dead old man, I'll let you go for the time being, you wait for me!"

Let me hurry over and chase Du and forget.

At this time, it was already dark, and Du Yiyi had to walk into the cave with a torch, and after a while, Duan Sisi and Shao Yuanying naturally followed one after another.

Du did not forget to ask Shao Yuanying:

"Uncle Shao, what's in here?"

Shao Yuanying smiled:

"Isn't there a bunch of bananas in there?"

Du did not forget to smile bitterly:

"Uncle Shao, don't make trouble, we're going to do something big now!"

Shao Yuanying's expression also became serious:

"Okay, I'll tell you, this cave can lead directly to an ice cellar in the Shangqing Palace, and in addition to some fruits, there are also some ulterior things in the ice cellar. ”

Duan Sisi asked curiously:

"Dead old man, what is the secret in it?"

Shao Yuanying showed a mysterious smile:

"You'll know when you arrive. ”

After walking for a while, the three of them couldn't help but feel a burst of cold air coming, and Duan Sisi was directly shivering with cold.

Du didn't forget to see Duan Sisi like this, so he took off his coat and put it on her.

After bypassing a corridor, they pushed open a stone door, and the three of them arrived at a huge ice cellar, which was probably the size of the entire palace Taihe Palace.

On both sides of the ice cellar, there are some fruit plates, on which are placed fruits from all over the east, south, and north.

As soon as Shao Yuanying and Duan Sisi saw these fruits, they stepped forward to take them and ate them, and after Du Yiyi also took an apple and ate a few bites, they continued to walk forward.

After a while, I found that there seemed to be a room in the ice cellar, approached the room and took a look, only to see that there seemed to be a steaming ice bed in the room, Du did not forget to go forward curiously to touch it, and was instantly shocked, I didn't expect this ice bed to be warm, not hot at all, and it was very comfortable to touch.

Suddenly, at this time, I heard Shao Yuanjie's voice behind me:

"Brother Du, you still have a good eye, and you actually know that this bed is a treasure. ”

Du Bu Bu turned around and found that Shao Yuanying and Duan Sisi had already entered the room at this time, so he asked:

"Uncle Shao, what is this bed made of, and how does it feel so comfortable to the touch?"

Shao Yuanying smiled:

"This is actually not a bed, it is a warm jade coffin, but on top of this coffin is a suitable place for practice. ”

Du did not forget to quickly push back a few steps:

"Uncle Shao...... You say...... This...... Is this a coffin?"

Shao Yuanying nodded:

"Yes, it's a coffin, but there's no human presence in this coffin!"

Duan Sisi on the side was very curious:

"This coffin doesn't hold people, isn't it a waste to put it?"

Shao Yuanying spoke.

It turned out that this warm jade coffin was left by Zhang Tianshi, who was also the ancestor of Daoling, more than a thousand years ago, and Zhang Tianshi originally planned to make this warm jade coffin a temporary storage place for his body after his ascension, so as to ensure the eternal existence of his body, but later for some reason Zhang Tianshi did not use this warm jade coffin.

Hundreds of years ago, there was an unknown Taoist priest in the Shangqing Palace and a woman from a good family under the mountain had a private meeting in the Shangqing Palace, and the two of them accidentally escaped into the stone room.

At that time, because it was a once-in-a-century winter, this stone room opened to the cliff outside, and it was naturally extremely cold, and the Taoist priest and the woman were naturally frozen and had nowhere to hide, so the two had to hide behind this coffin.

Slowly, the two of them found that they actually felt heat coming out of their backs, and the Taoist priest immediately turned around and touched the coffin behind him, and found that although the surface of the coffin was full of dust, it was made of warm jade, which was naturally a surprise.

The two of them quickly wiped off the coffin dust, and then lay on it, and the two of them actually realized the method of dual cultivation for men and women on this warm jade coffin.

After listening to it, Du Buyi was surprised:

"Excuse me...... The dual cultivation kung fu I once learned from Bai Qingtian, the leader of the White Lotus Sect, was it realized by the Taoist priest and the woman on this warm jade coffin hundreds of years ago?"

Shao Yuanjie nodded:

"I heard that it seems to be, but since this warm jade coffin was discovered, the successive masters of the Shangqing Palace have basically regarded it as a holy relic, never let anyone approach, and never enter here, almost all of the people who can enter this ice cellar are their closest people. ”

Duan Sisi stopped these clouds that seemed to be clouds:

"Brother Du, double cultivation, what kind of martial arts is it, is it really that powerful?"

Du Cheng said:

"Sisi, it's better that you still don't want to know, I can only tell you that this double cultivation is a kind of male and female exercises. ”

Duan Sisi grabbed Du Yiyi's arm tightly:

"Brother Du, then let's go up here to practice a double rest, maybe we can be invincible in the world after we practice, and even Shao Yuanjie, who claims to be the number one master in the world, is also defeated by our subordinates?"

Shao Yuanjie laughed a few times at Duan Sisi:

"Dead girl, you really don't know how to be ashamed, and you still want to practice double cultivation with your big brother Du?

Duan Sisi glared at Shao Yuanjie:

"Do you think I don't know? Isn't double cultivation just two people sitting on this warm jade coffin and practicing martial arts together?"

Shao Yuanjie pointed to Duan Sisi:

"Girl, you're so naïve, okay, I won't bother you, I'll help you keep an eye on the ice cellar door in case someone suddenly comes down. ”

And when he had said that, the man ran out.

At this time, Duan Sisi kept pestering Du Buyi, asking Du Buyi to take her to the warm jade coffin to practice, but Du Buyi had no choice but to agree:

"Okay then, I'll practice with you for a while, remember to only practice for a while, you know?"

Duan Sisi nodded:

"Okay, as long as you accompany me to try out what this double cultivation is like. ”

Du did not forget to remind again:

"You remember, you and I are not all the way to martial arts, if there is anything abnormal in your body later, you must stop, you know?"

Duan Sisi nodded excitedly:

"Okay, Brother Du, I'll listen to you whatever you say. ”

The two of them climbed the mountain to warm the jade coffin separately and sat together to practice kung fu.

Du Bu Bu is also practicing on this kind of warm jade coffin for the first time, and naturally he also wants to try if his internal martial arts can go further, after all, in the past two years, his internal martial arts seem to have stagnated, and he can't break through.

Duan Sisi practiced for a while, and saw that Du had been practicing him by himself, and he didn't care about himself at all, so he was a little angry:

"Brother Du, didn't you say that you would accompany me to double cultivate? Why do you only care about practicing by yourself now and ignore me at all?"

Du didn't forget to run the true qi in his body a few times, and wanted to break through, but he still couldn't break through, which was made by Duan Sisi again, so he had to stop and said:

"Sisi, isn't this a double cultivation, what kind of double cultivation do you want?"

Duan Sisi directly pulled Du Yifu's palm, and said with his palm:

"I've heard that other people's double cultivation practices like this, let's try it too!"

Du Chu did not forget to nod:

"Okay, then let's practice with you, you remember, if you feel any discomfort, you have to tell me right away, you know?"

Duan Sisi nodded:

"Brother Du, you've said it a few times, I know, okay?"

At this time, Du Buyi slowly felt another breath from Duan Sisi's body leading towards him, so he quickly collected this breath, and after running around with the true qi of the Buddha Dao in his body, it was led back into Duan Sisi's body.

At this time, a feminine qi came out of Duan Sisi's body and entered Du Buxin's body, so Du Buyi combined this feminine qi with the masculine qi in his body, and then transmitted it back to Duan Sisi's body.

When accepting the true qi in Duan Sisi's body again, Du Buyi found that this true qi didn't seem to be as strong as the two feminine qi before, and after something was wrong, Du Buyi quickly opened his eyes and glanced at Duan Sisi, and found that at this time, Sisi was sweating, and his face was red, and he seemed to be very uncomfortable.

Du Bu didn't forget to quickly withdraw his palm, but he didn't expect Duan Sisi to say:

"Brother Du, don't ...... Don't, I'll hold on!"

Du Buyi saw that Duan Sisi was unwilling to accept his palm at this time, and his rash withdrawal of his palm would inevitably hurt her, so he hurriedly persuaded:

"Sisi, don't insist like this, take it quickly, otherwise you will go crazy!"

At this time, Sisi suddenly untied the skirt behind her with her other hand:

"Brother Du, don't stop, I'm just a little hot!"

Seeing this, Du did not forget to ask:

"Sisi, what are you going to do?"

Duan Sisi seemed to have faded half of his long skirt at this time, revealing the red belly inside.

Du Buyi also found that his body was actually starting to heat up at this time, and this heat was generally from the body, and the other half seemed to come from the warm jade coffin.

And Duan Sisi's hand actually began to relieve his belly at this time, and Du Sisi didn't dare to withdraw his palm, because the true qi in the two of them was now connected together, and if he rashly withdrew his palm, not only would he be injured, but Duan Sisi would also lose his life.

As the body became hotter and hotter, Du never forgot that he had no choice but to unconsciously remove his clothes with his other hand.

After a while, the two were naked and facing each other.

Unexpectedly, after facing each other naked, the heat on the two of them just now actually began to slowly disperse, and the true qi in the bodies of the two of them was actually connected together, and they kept wandering and staggering in the bodies of the two people.
