What is Inner Dan? Collect the aura of heaven and earth, and absorb the sun and moon and the emperor.

What is Waidan? Gather the essence of the five elements and train all living beings.

Seeking the Tao and cultivating is originally a kind of plundering of all things in heaven and earth, and naturally it has received great cause and effect with this heaven and earth. On the path of cultivation, there are many checkpoints, which are not only tests, but also the means by which the Heavenly Dao keeps cultivators out.

The inner dan is the foundation of cultivation, but the outer dan is just the way to seek the Tao. No matter what the outer pill is, in the end, it is still used to nourish the inner pill, and the cultivation of the Dao to seek immortals is not a mixed yuan purple gold pill in his body?

The strange spirit peach in Zhou Cheng's hand is a kind of Waidan. The essence of plants and trees has a peaceful temperament, and has always been the first choice of Waidan. Without two brushes, refining mercury is pure death. Countless ancient princes and generals confirmed this with their lives.

If Zhou Cheng has already achieved the golden pill now, this spiritual peach is undoubtedly the best elixir. But for Zhou Cheng, who is now only stepping on the threshold with one foot, the spirit peach is poison!

But isn't this a temptation? a temptation that you know you can't do but can't let go.

Zhou Cheng thought about it again and again, but finally didn't dare to joke with his own life, resisted the temptation, and put the spirit peach aside. Even if the old man had already told him to eat the spirit peach first when building the foundation.

Zhou Cheng would rather lose time than gamble on his own.

On the top of the mountain peak, Zhou Cheng crossed his knees and began to meditate, slowly urging the spiritual energy in his body to parade through the hundred veins, driving the air above the mountain peak to form a small spiritual energy vortex.

One day passed, two days passed, and on the third day, Zhou Cheng's forehead began to sweat slightly, and his breath was obviously a little unstable.

Zhou Cheng thought about building the foundation too simply, and he didn't have time to understand how much difference the amount of aura needed to build the foundation was different from the amount of aura needed to enter the body and practice meditation. When he began to compress the aura in his body piece by piece and merge into the dantian, he found that the aura around him was too thin, and Zhou Cheng had slowed down his pace as much as possible, but he never expected that the aura around him was already thinner. The aura inhaled around him couldn't catch up with the consumption at all, and after accumulating little by little, when Zhou Cheng realized that something was wrong, there were signs of spiritual energy drying up in his meridians.

The big river has water, the small river is full, the small river has no water, and the big river is dry. Zhou Cheng noticed the abnormality of the aura in his body. It's just that the cultivation is like a sharp arrow off the string, only to move forward, but there is never a way back. This is not a daily meditation to induce breath, and you can stop when you say stop. As the aura in Zhou Cheng's meridians gradually dried up, the aura contained in Zhou Cheng's dantian began to gradually slow down, and in the end, not only could the aura no longer be able to be stored in the dantian, but the aura in the dantian gradually began to show signs of counterflow.

What does it mean to ride a tiger and be in a dilemma? Zhou Cheng is now!

As the aura whirlpool around Zhou Cheng came to an abrupt end, Zhou Cheng had already stepped on the threshold of life and death with one foot on the broken tendons and broken dantian.

The abnormality on the top of the mountain naturally can't be hidden from the old man at the bottom of the mountain. Seeing the whirlpool on the top of the mountain where Zhou Cheng was retreating, the old man just sighed and knew in his heart.

In the final analysis, Zhou Cheng's predicament had long been expected by the old man. In the final analysis, the old man has taken care of him too much over the years, so that Zhou Cheng's cultivation path is too smooth, and his experience is too shallow. If you don't go through life and death, it is difficult to become a big tool, and you underestimate the hardships and dangers on the road of repair!

"The fairy road is beautiful, but it is difficult to seek the way. Half a step away is the difficulty of life and death. Old man, I can protect you for a while, how can you protect you for a lifetime?" Although the old man had expected it in his heart, he really saw Zhou Cheng in a life-and-death crisis, and the old man was also very unhappy.

As the saying goes: The master leads the door, and the cultivation depends on the individual. This is especially true for cultivating and seeking immortals. Most of the immortals taught apprentices were just a "book from heaven" to send things away. Success or failure is up to people, life and death are up to heaven. If we rely on people to support and teach everything, how can we achieve positive results one day?

Zhou Cheng disappointed the old man...

The old man was disappointed, but how could he really leave Zhou Cheng alone?

"Yin and Yang creation, all things turn into stars, the two instruments return to their places, and the eight directions are locked!" As the dust moved, the array flags around Zhou Cheng suddenly burst into glory and rose from the ground. Later, with the old man's spell order, he began to rotate around Zhou Cheng rapidly, and at the same time stirred the wind and clouds around the mountain peak, quickly forming a large whirlpool that squeezed and rotated from the outside to the inside.

"Get up!" The old man saw that the whirlpool had been completed, and then swept away the dust, far above the top of the mountain, a green light suddenly flashed, and the saturation next to Zhou Cheng suddenly opened, and the thick spiritual mist rose from the treasure box in the whirlpool, and then was squeezed by the whirlpool outside from the outside to Zhou Cheng in the center of the whirlpool.

Zhou Cheng was still entangled with the aura in his body at this time, seeing that the retrograde of true qi had become irreversible, Zhou Cheng himself knew that the general situation was not good, suddenly a spiritual pressure struck out of thin air, and the dried meridians were instantly filled with external aura, and the aura that was about to go against the pulse was instantly restored to control.

But just when Zhou Cheng didn't have time to breathe a sigh of relief for the sudden aura, Zhou Cheng suddenly found that he seemed to have encountered a bigger problem.

Droughts kill people, and so does floods.

Zhou Cheng had just passed the aura retrograde, and the ghost gate of the dantian collapsed. But I didn't expect that I would start to fight hard for the blockage of the aura in my body again. Because the surrounding spiritual pressure was too great, even if Zhou Cheng didn't take the initiative to draw qi into his body, the spiritual energy began to flow in from the outside.

Zhou Cheng's vein capacity was limited, so in order to dredge the meridians, he had to increase the operation of the aura, and transport the aura, which was about to burst in the meridians, to the dantian. But he didn't expect that the aura in Zhou Cheng's body began to operate, and the aura around him was surging like a flood that opened the floodgates, far exceeding the limit that Zhou Cheng could carry.

Zhou Cheng is still difficult to ride a tiger, and he is in a dilemma. On the top of the mountain, Zhou Cheng once again stepped on the threshold of the tendons and veins being broken and the path of life and death was eliminated. The only difference is a change of direction.

Last time, I starved to death, but this time I really died.

In order to channel the aura in his body, Zhou Cheng had to desperately accelerate the flow of aura in his body, but the faster the aura flowed, the more aura poured in. Cycle after week, Zhou Cheng was forced to speed up the circulation step by step, and he was also walking towards the abyss step by step.

On the top of the mountain, the sweat on Zhou Cheng's forehead not only showed no signs of reduction, but became more turbulent. The flow of spiritual energy accelerated the flow rate of blood throughout Zhou Cheng's body. Zhou Cheng's face became redder and redder, and bursts of white smoke rose from his body. The whole person was like a boiled shrimp, and it didn't take long for the whole body to faintly begin to ooze black and red blood and sweat.

If there is hell on earth, Zhou Chengcheng feels that he is in hell now. Zhou Cheng couldn't control the aura in his body now, Zhou Cheng only felt the pain of the meridians of his body breaking inch by inch, and only felt the heat of his whole body like a burning fire.

After all, the circulation of spiritual energy cannot catch up with the speed of the influx of external spiritual energy, and the fragile meridians in the body cannot withstand the rapid circulation of spiritual energy. Zhou Cheng felt the burning of the five internal organs in his body, and felt that his seven meridians and eight veins were blocked, expanded, and then broken.

The pain of life is nothing more than this, but Zhou Cheng's consciousness is extremely clear, and he can't even faint to death.
