In an instant, Su Mu came to strength, all the pain was swept away, and he hurriedly sat cross-legged and cultivated to recover.

That night, Su Mu stopped cultivating, and his injuries had already healed, but he was still far from healing.

But this state is the best time to open a second dark vein!

took out the school card, looked at the numbers on it, and the corners of his mouth raised.

"More than six thousand seven hundred credits, enough to cultivate for a long time!"

With these credits, open up the second dark vein, and condense the yuan liquid is not in vain!

After taking a shower and changing clothes, he left the dormitory, and after glancing at Guan Yifei's dormitory, he turned around and walked towards Feng Lingjian, now Huang Yiyun's condition will not deteriorate again, and opening up a second dark vein will make her wake up.

When he arrived at the Wind Spirit Stream, Su Mu jumped into the cave where he had cultivated before, even if he had more than six thousand credits now, he couldn't be too extravagant, if his vitality was enough, he would cultivate it temporarily, and if it wasn't enough, he would change it again.

He sat in the cave and practiced for two days.

"The cultivation speed of the rebirth realm double has really gone to a new level, and the yuan liquid has been restored in two days."

Looking at the two hundred drops of Yuan Liquid in the sword vein, Su Mu couldn't help but be happy, with the Yuan Liquid, he had a sense of security, and he was more confident in opening up the second dark vein.

The one hundred drops of Yuan Liquid that were burned off were much more difficult to recover than the Yuan Liquid consumed when they broke through the realm, but it was much easier than the hard work they had before, and the speed of realm improvement and cultivation had accelerated, reaching the speed of fifty drops per day.

"Now it's time to open up the dark veins."

Su Mu took a deep breath, feeling a little apprehensive, last time it was the sword vein that the mad Immortal Emperor helped him open up, and this was the first time he opened up the dark vein.

Running the two hundred drops of yuan liquid in the sword vein, one hundred drops were separated, and they traveled around the body for a week, looking for the best place to open up the dark vein.

"Let's open it up in Zhongdantian."

Looking for a circle, Zhongdantian is the best location.

The human body has three dantians, which are divided into upper, middle and lower dantians, and the lower dantian is in the abdomen, that is, the navel position; The middle dantian is in the middle of the chest, in the most central position of the chest, also known as the Jiang Palace; The upper dantian is located in the center of the eyebrows, also known as the mud pill palace.

The lower dantian is also the positive dantian, which is related to the cultivation of the martial artist's life, and the middle dantian is the gathering of the sect's qi, and it can be opened up to ensure that the heart does not stop and life is endless!

The consciousness of the master of the upper dantian can be opened up to make the soul immortal!

"Zhongdantian is such a good location, you are only willing to accommodate one Tianzun power?" Inside the Futu Tower, the madman Immortal Emperor couldn't help but say, such a good place in the middle dantian is used now, it's a waste.

Hearing the voice of the Crazy Immortal Emperor, Su Mu was stunned for a moment, and then he didn't say anything, waiting for the next step of the Crazy Immortal Emperor.

"Zhongdantian can't be used casually, have you forgotten that your heart is a seven-trick exquisite heart?"

"Once you use it like this, then you will miss the opportunity to open up the Nine Exquisite Hearts!"

Hearing this, Su Mu broke out in a cold sweat on his head, fortunately, there was a reminder from the Crazy Immortal Emperor, otherwise he would have missed the Nine Tricks Exquisite Heart.

The Nine Tricks Exquisite Heart is the heart of the immortals!

Missing it is a huge loss!

"Don't move the Middle Dantian and the Upper Dantian for the time being, at least the Heavenly Venerable level power is not qualified to occupy your Middle Dantian and Upper Dantian yet!" After that, the madman Immortal Emperor fell silent.

After hearing this, Su Mu smiled bitterly, Tianzun-level strength, he only has the share of looking up now, and he is actually said to be unworthy, if this is heard by others, I don't know how it will feel.

"Then let's open it up in the Neiguan Cave."

Su Mu opened his eyes and looked at his hands, the power was basically output through his hands, and opening a dark vein on his arm was undoubtedly a very suitable choice.

And the madman Immortal Emperor said before that there is Ice and Fire Tianzun in the first layer, ice in the left hand, fire in the right hand, a blend of ice and fire, and a strong force!

Immediately closed his eyes and began to control the hundred drops of Yuan Liquid to impact the Neiguan acupoint!

"Humph!"

Almost instantly, Su Mu's eyes widened, and sweat rained down!

With just one impact, he already felt like his arm was about to break!

"If you want to become stronger, what is this pain, rush me!"

Su Mu's expression became hideous, and he continued to control the hundred drops of yuan liquid to rush towards his arm!

"Humph!"

The second impact, Su Mu knelt down directly, his left hand was weakly placed on the ground, and at this moment it was so painful that he wanted to cut off his arm.

"Boom!"

With a fierce face, he pulled out his sword, then threw it on the ground, pulled the scabbard from his back and bit it in his mouth.

Biting the sword, he didn't dare, and his tongue was gone if he was not careful.

"Humph!"

The third impact, a row of tooth marks appeared directly on the scabbard!

"Go on!"

"Humph!"

……

I don't know how many times he was shocked, Su Mu only felt that he was already in pain to the point of confusion, he was so nostalgic for the madman Immortal Emperor to open up the sword vein for him at the moment, even if it was painful, it was only a short-term pain, how could it be like now, it was like this, it was like torturing himself to death.

"Open it for me!"

roared in his heart, Su Mu's eyes were already bloodshot, and the impact was now that the dark veins were about to open up, and he must not give up halfway!

"Buzz!"

With the impact of the force, Su Mu's head buzzed, and he fell directly to the ground with his head up, fainting.

It wasn't until the next day that Su Mu woke up leisurely.

"Has the dark vein opened?" After waking up, Su Mu knew that he had fainted from the pain yesterday, and hurriedly looked inside to explore his arm.

I saw that at the Neiguan acupoint, a dark vein existed!

The size and solidity of the second dark vein are not inferior to the sword vein at all!

"Hahaha...... It's worth it, it's worth it! ”

Seeing that the second dark vein was so strong, Su Mu laughed heartily, no matter how big the pain was, it was worth it!

"It's just a matter of devouring the soul to fill the dark veins!" Su Mu's eyes flashed with a fine light, without the filling of divine soul power, the dark veins that had been opened up would not take long to close, and he didn't want to endure that kind of inhuman pain and torture again.

Sitting cross-legged, consciousness goes directly to the Floating Pagoda.

On the first floor of the Futu Tower, it was still white, and the figure of the madman Immortal Emperor appeared in front of him.

"Senpai." Su Mu raised his hand and clenched his fists, seeing that the soul state of the madman Immortal Emperor was much more transparent than before, and secretly believed in his heart that he must be desperate to get the medicinal liquid and medicinal materials that restore the soul!

The Madman Immortal Emperor nodded, didn't say anything, raised his hand, and a figure walked out of the white mist.

Su Mu's eyes immediately fell on that person, and his face couldn't help but raise his surprise, what appeared in front of him was a young man, wearing an ice blue robe, handsome and elegant, just a weak scholar, it was hard to imagine that this was a terrifying Tianzun-level figure.

"Don't look at him young, in fact, he was thousands of years old before he died." The voice of the madman Immortal Emperor sounded, "The reason why he looks young is because of his ice power. ”

Su Mu bowed slightly, low temperature does have the effect of eternal youth, it seems that the ice power is definitely a woman's favorite power.

"Crazy Immortal Emperor!"

Bing Zun didn't even look at Su Mu, his eyes fell on the madman Immortal Emperor, and the temperature in the Futu Tower dropped sharply in an instant, and those fluttering white mist instantly turned into ice!

Su Mu immediately shuddered, and gasped, not only the low temperature, but Bing Zun was able to condense all the white mist in the Futu Tower into frost, and those white mist were not water vapor, but the pure power in the Futu Tower!

was able to freeze all the energy, Bingzun, it was really terrifying!
