"Boom!" There was a loud bang, and the Dan furnace shattered, scattering fragments, and among them was a pill that glowed with seven colors of light.

Cheng Ming's eyes were quick, and as soon as he jumped up, he took the pill in his hand, and felt the breath of the pill, and he breathed a sigh of relief.

Originally, he thought that he would be able to refine the pill smoothly, but he didn't expect that when Ning Dan was condensed, the Dan furnace began to vibrate violently, and seeing that it was going to be worse, he had to add the input of true qi to speed up the matter of Ning Dan.

As a result, it didn't take long for the Dan furnace to explode, but fortunately, Ning Dan finally succeeded at the last moment, otherwise he would have wanted to cry without tears.

Cheng Ming hurriedly used his divine mind to check, and found that the fourth-order spirit beast was still asleep, so he checked the Mulberry Pill and found that the medicinal properties were the same as those introduced in the book, and he laughed happily. But after a while, his expression became sad again.

Originally, he still thought that if he couldn't go out, he would cultivate here, and wait until he had successfully built the foundation to go out. But there is a prerequisite for this, he has a Dan furnace to practice Dan, and now that the Dan furnace is broken, he only has to rely on luck to find other ways to get out.

"Why isn't there a spirit stone mine in this place? ”

Cheng Ming muttered, cleaned the cave and made his body breathe to the best state. Only then did he solemnly take out the Mulberry Pill and put it in his mouth.

As soon as the mouth of the Muldan was in his mouth, it turned into a sweet juice and fell into his stomach, and immediately after, all kinds of strange sensations came, cold, fiery, heavy, sharp, and vibrant, as if he had learned all the power of the five elements together.

For Cheng Ming, this is a rare opportunity, and he quickly memorized the five feelings in his heart. However, before he could experience it, a sharp pain came.

Speaking of which, Cheng Ming had some psychological preparations before, but the pain was unbearable for ordinary people, as if he was going to stir up all his internal organs and completely tear his body apart.

But in the process, he couldn't move at all. Otherwise, he would fail, he could only grit his teeth and insist, and after a while, the corners of his mouth were bleeding from the bite of his gums.

I don't know how long it took. The severe pain slowly dissipated, and there was a tingling sensation on his body, as if there were thousands of ants crawling, and the feeling became stronger and stronger, and he wished that he could faint at this time.

Cheng Ming persisted day by day. Just when he felt that he couldn't hold on anymore and was about to give up, a warm current began to emerge in the position of the dantian, and the itchy feeling was swept away where the warm current went.

In an instant, all the discomfort disappeared, and Cheng Ming felt that the cells in his whole body seemed to be dancing happily, and the extremely pleasant feeling made him intoxicated.

Slowly, the impetuosity in his heart began to subside, and the dirt on his soul gradually disappeared. There are no more distracting thoughts, and there are no waves in the ancient state of mind.

Although his eyes were closed, everything around him seemed to turn into an ink painting at this moment, reflected in his mind. Immediately afterward, his divine thoughts began to expand, revealing the cave mansion and rising above the nine heavens, overlooking the earth.

The sea of clouds, grasslands, mountains, lakes, and incomparably beautiful natural scenery have become landscape paintings. It was as if he were nature, and nature was him.

At this moment, Cheng Ming's state is very mysterious, if the foundation building period monks of the Central Continent are here. They will definitely be surprised, because this is exactly the realm of the unity of heaven and man that they dreamed of during the foundation building period. Immerse yourself in nature and become one with heaven and earth.

However, this realm was so ethereal that the vast majority of Qi cultivators could not reach it until they died, so they could only rely on the Tsukidan to break through to the Tsuki-Tsui Stage.

Although it seems that taking Tsukidan is naturally no different from relying on understanding. Cultivating two of the same exercises, the latter will not be much stronger than the former, but those who understand naturally know that those who break through on their own will inevitably go further.

Cheng Ming didn't know that he had unconsciously entered a state of unity between heaven and man, he only felt that he was carefree at this time, no longer anxiously thinking about how to improve his strength, and no longer thinking about how to go home as soon as possible.

There was no longer a trace of worry or sorrow in his heart, and he suddenly felt that his mind was extremely clear. At this time, he thought that the sword intent, which had already fallen into a bottleneck, and those spells that he felt he was already very proficient in, might be able to go further.

However, just as he was opening his mouth, he saw a huge palace suddenly rise in the west, and the palace shimmered with golden light, as if it was beckoning him to hurry over.

"What's going on with the palace, is it the so-called inheritance left by the Yang God True Man?"

Cheng Ming had some doubts in his heart, and then he reacted: "By the way, I am in the sky, why are those demon beasts and elixirs missing?"

Thinking of this, he felt that something was wrong, and then, he felt his body sink, and his thoughts returned to his body.

A trace of confusion flashed in Cheng Ming's eyes, and immediately, a look of shock appeared on his face, he didn't expect that just now for a while, he actually broke through to the sixth layer of qi refining.

"Isn't it, could it be that taking Mulberry Pill actually has such a great effect?"

"After all, the Five Elements Yin Yang Lotus is an earth-treasure level spiritual object, plus you have entered the realm of the unity of heaven and man, it is normal to have such an effect, if you are in the surface world, you can completely upgrade to three levels in a row. ”

The voice ringing in his ears made Cheng Ming first startled, and then there was a burst of ecstasy: "System, you finally appeared! I thought I didn't know how long it would take to see you again." By the way, can I go back to the watch world now......"

Speaking of this, his mood suddenly dropped: "It's been a few months, my parents should think I'm dead." ”

The system said, "Who told you that time and the watch world here are synchronized?"

"What!" Cheng Ming was pleasantly surprised: "You don't mean to say, just like in myths and legends, a year has passed here, and the watch world has only passed for a day, right?"

"Now it's true to what you said, but it's not without a price. ”

"What price?" Cheng Ming hurriedly asked.

"Psionic energy, you have to use psionic energy in exchange, and now this time ratio, you need a hundred psionic energy. ”

Hearing that only one hundred spiritual energy was needed, Cheng Ming immediately relieved himself, he still had hundreds of spiritual energy, so he didn't have to worry about it at all.

However, the system's words poured cold water on him again: "Don't be too happy, because you rashly planted the Five Elements Spirit Tree this time, which caused the small world to upgrade ahead of schedule, the remaining spiritual energy has been absorbed by the small world, but it is far from meeting the requirements of the small world upgrade." ”

Cheng Ming was dumbfounded: "What do you mean? You don't mean that I need to upgrade the small world before I can go back, right?"

"Yes. ”

The corners of Cheng Ming's mouth twitched: "How much energy does it take to upgrade the small world?"

The system was silent for a moment: "I can't estimate this." ”

Cheng Ming was stunned for a moment, then took a deep breath: "Just tell me, what's the good news?"

"Now you can still use that space in the small world, everything in it is there, and the imp is not dead. In addition, your Sumeru ring can now be put into a small world. ”

Cheng Ming frowned: "You mean to say that let the little ghost go to the watch world to help me do things? Is this feasible? Can he still enter the small world when he goes out?"

"Just have me. ”

"Yes!" Cheng Ming patted his forehead, feeling a little stupid.

"I'll let the imp bring your Sumeru ring now, and then I'll fall into a deep sleep again. ”

Cheng Ming was stunned: "Why did you just wake up and go to sleep again?"

It's just that the system didn't answer, and after a while, he saw an ignorant little ghost appear in front of him with a Sumeru ring.

"See you in a month!" the system put down the sentence, and there was no more sound.

"Lord...... Master, what the hell happened before, it scared me to death!"

The little ghost patted his chest in fright, and then hurriedly handed over the Sumeru ring to Cheng Ming, and then began to look around, and immediately he found that the aura here was many times stronger than that of the surface world.

This made him ecstatic, and he shouted: "Master, what kind of blessed land is this, the spiritual energy is so abundant! If I can cultivate here for a year, I will definitely become a ghost general!"

"Alright, don't scream, there's a fourth-order Wind Splitter Fox outside, if you bring it in, I'll give it to you for breakfast." ”

Cheng Ming waved his hand a little impatiently, at this time he was very depressed, he couldn't even estimate how much energy the small world needed, and the amount would obviously not be less. With so much energy, it is definitely not possible to collect it all in a while.

"It seems that I have to fight a protracted battle, and fortunately, there are little ghosts who can pass on the word, otherwise, my parents will not die in a hurry!"

Since the matter has come to this point, he can only face it calmly.

That's right!

Cheng Ming's eyes lit up, isn't there a chance to get the inheritance now? This is the inheritance left by the Yang God Zhenren, and there will definitely be no fewer treasures in it, even if it can't meet the requirements of the small world, it must be almost the same.

"No, you must get that inheritance!"

Cheng Ming clenched his fists, and then shouted: "Let's go!"

As soon as the words fell, the little ghost said weakly, "Master, aren't we going to cultivate here for a while?"

Cheng Ming waved his hand: "In the future, there will be time to cultivate, by the way, with your strength, you can only stay in the small world." ”

The little ghost suddenly hugged Cheng Ming's thighs and begged bitterly: "Don't! Master, you still let me stay by your side!"

"I don't have time to take care of you, take it!" As he spoke, Cheng Ming gave the little ghost a spirit stone.

This made the little ghost take the spirit stone in surprise, and said again and again that with this spirit stone, it is no different here or in the small world.

"By the way, how long has it been since the change in the small world?" Cheng Ming suddenly thought of the question of time, so he asked the little ghost. (To be continued.) )
