After that, Xu Yi found that his seal had been unsealed, and the dantian could mobilize his aura and move freely.

After knowing this, Xu Yi was stunned at first, and then ecstatic in his heart.

She was kidnapped by Lao Dao for no reason, and used it as medicine for alchemy, but this Lao Dao would never have thought that these medicinal powers were the key to Xu Yi breaking through the tail acupoint.

If the alchemy fails, it will be a wedding dress.

Under normal circumstances, it would take a few days for Xu Yi to break through the tail lu acupoint before he could try to impact the second layer of qi refining, and whether it succeeded or not depended on the will of heaven.

Now that she is not dying, but has such a strong and pure medicinal power, her body has already accumulated a huge amount of energy, and this is an opportunity to break through.

Xu Yi calmed down, drew qi with intention, and began to try to guide the huge energy towards the tail acupoint.

Zizi!

The moment the energy was mobilized, Xu Yi's body crackled, and her heart trembled slightly, this energy was majestic and mighty, as if it had the ability to destroy the world and destroy the earth.

"How can you survive when you are born in the world. Although it is a desperate situation, there is also a glimmer of life, which needs to be firmly grasped. ”

Xu Yi gritted her teeth, and the energy she tried to restrain was instantly released by her, like a roaring thunder, smashing into the barrier in front of her.

Rumble!

Inside the stone cave, the black tripod suddenly shook, and a dull explosion exploded in the tripod, and the entire black tripod seemed to have swelled in a circle due to the explosion, bearing unimaginable damage.

The leper was lucky to control the fire, and this sudden movement frightened him, and the aura in his body was disordered, and the fire under the ding grew wildly, and the fire was fierce in vain.

"What a move!"

Lao Dao blew his beard and stared, and hurriedly breathed the aura, and after the aura subsided, Lao Dao looked at the black tripod, and heard the sound of "crackling" in the tripod.

"It's ...... Signs of Ningdan? Right! It must be the sign of the Ning Dan, and only when the Ning Dan will there be such a vision! The old man was overjoyed, and the wrinkles on his face stretched out like a blooming daisy.

He didn't think that this movement was caused by Xu Yi's impact on the tail point.

Lao Dao patted the storage bag, took out a few pills and swallowed them, and when the aura was almost recovered, he began to re-condense the qi and control the fire.

"The most critical time is the condensation of the pill, this is the time when the medicinal power is mixed and condensed, regardless of the fire, temperature, or the Dan furnace will affect it, once there is a mistake, the medicinal power will be repulsed, resulting in the failure of the condensation. And once Ning Dan fails, it will be the end of Ding Bang Dan. ”

Lao Dao carefully urged the aura, and the spirit was raised to the extreme, guided by divine consciousness, so that the fire was slowly slowed down, and he did not dare to be careless.

Bang!

Sound... Syllable!

Listening to the sound of the explosion in the ding, Lao Dao was not only worried, but became more and more energetic.

Such a vision shows that the medicinal power is extracted very sufficiently, and the effect of Ning Dan is even better! Sent a ......"

Dingnei.

Xu Yi was also extremely nervous, the veins of the wall like a copper wall had been torn open a small hole, but just a hole had exhausted the medicinal power accumulated before.

This made Xu Yi slightly surprised.

"When I opened up the dantian, I didn't have such a hard time, and even the perineum was not very difficult, but this tail acupoint was several times more difficult."

Xu Yi breathed and breathed, ready to reabsorb the medicinal power and start the next round of impact.

That leper old Taoist has created such a unique cultivation environment for her now, and Xu Yi must speed up the improvement of her strength and increase her chances of survival.

Otherwise, after waiting for seven days, Lao Dao Kaiding found that not only was he not dead, but he also absorbed the "medicinal materials" he prepared for alchemy, and he would definitely put her to death

After all, this is the "medicinal material" used by the old Tao to break through cultivation and increase longevity.

"Life should be like the brilliance of jade, the dazzling gilt, the peak of the world, the small of the mountains, the weak pass away, and the fittest survive." Xu Yi's eyes were burning, and her cold eyes flashed with determination, she wanted to control her own destiny.

Soon, Xu Yi re-condensed the majestic medicinal power and began the second round of impact on the tail acupoint.

Bang!

Outside Dading, Lao Dao saw that the crackling sound gradually dissipated, thinking that Ning Dan had been completed, and was about to collect the fire to stabilize Dan's nature, but was frightened by the sudden explosion again.

"Why is there any movement again?"

The old Taoist shook his hand, and the fire was almost uncontrollable. He stared at Da Ding vigilantly, suspicious in his heart.

"I have been in the world for more than 200 years, and I have not heard of the vision of the two Dan lines, but I have only heard that the Dan has Dan patterns. The more Lao Dao thought about it, the more he felt that it was very likely to produce Dan patterns.

"This is a Dan pattern, a Dan pattern that is not more than one in a thousand!"

The fire in his hand was unabated, and his mood was stirring. When I thought of the Danwen coming into the world, it was still from my own hand, but I longed for it.

Rumble!

The explosion continued to sound, and Dading began to tremble violently, and the sound of tremors continued to sound.

Lao Dao did not worry about it, but rejoiced, maintaining the fire to maintain balance, and the elixir in the storage bag was reduced at a very fast speed.

It lasted like this for nearly three hours, and Dading could be reduced to dullness.

Within the Great Ding.

"Whew~ Success!"

Xu Yi's eyes were burning, his eyes flashed, his chest continued to rise and fall, and he raised his hand to wipe the beads of sweat from his forehead.

Feel the surging aura in the body, like a turbulent wave, wave after wave, as if there are countless inexhaustible aura.

"Is this the second layer of Qi training?" Xu Yi couldn't help but sigh, and he yearned for strong strength even more.

But before Xu Yi could rest for long, the black token flashed again, and the cold aura swept in instantly, and began to frantically search for the medicinal power in the ding.

"Again?"

Xu Yi glared suddenly, feeling the majestic medicinal power pouring into his body again, Xu Yi didn't care about the joy after the breakthrough, and began to draw qi to the tail acupoint, ready to hit the life gate acupoint.

The so-called life gate is the door of the human acupoint, located in the center of the waist and eye behind the back, where the nerves of the human are.

You need to be cautious when attacking the door of life, and if you are not careful, you will be delirious and die.

Of course, the gate of life is also the shackles of the three layers of qi refining.

Qi training is divided into nine layers, the first three layers are the initial stage of Qi training, the middle three layers are the middle stage of Qi training, and the last three layers are self-evident.

However, the difference in strength between each layer is huge, and the difference in strength between the early and middle or late stages is even greater.

Therefore, the third and sixth layers and the ninth layer of Qi training are the three life and death tests during the Qi training period.

The path of cultivation is to fight with the heavens, fight for the destiny of the heavens, and go against the top, rather than going with the sky.

Xu Yi held his breath and stared, and the violent energy exploded in the meridians, like thunder, and the aura began to overflow in all directions.

Immediately, it rolled down.

Rumble...... Prosperous!

This time, Xu Yi's ears and nose, which were humming and trembling, were bleeding, his internal organs seemed to be disturbed, and his consciousness seemed to be chopped up and mixed together, and it was extremely chaotic.

And in the stone cave, this movement directly scared Lao Dao stupid.

After the loud noise, the black tripod began to redden, and the whole tripod began to beat "knock knock", as if something was about to rush out.

"This Dan is so powerful?"

Lao Dao stared at the scene in front of him in surprise, and his heart also beat with the red-hot ding, and every time he shook, the heat in his heart became fanatical.

Seeing that the big tripod was shaking more and more, the old way operated the fire with one hand, and the other hand made a seal, and with a "dang" sound, a palm slapped on the big ding.

"Town!"

Lao Dao sighed lightly, and the seal began to suppress Dading, and the power of the tide suppressed Dading until it calmed down, but in the ding, there was still a "crackling" sound.

Lao Dao smiled with satisfaction, revealing a mouth full of big yellow teeth, "In four days, Dan Kecheng!" ”
