A moment later, Gu Xiuyun followed Chang Bo back to the courtyard of the main vein.

This place is quite remote, surrounded by bamboo forests, if others do not look carefully, they will not think that there is a courtyard hidden in the bamboo forest.

"What a quiet place. Gu Xiuyun exclaimed.

"The old servant built a courtyard in the bamboo forest according to the instructions of the son, the time is in a hurry, the courtyard is a little simple, and I hope the son will not blame. Changbo bowed.

"It's too late for me to be happy, how can I blame you?" Gu Xiuyun smiled, he didn't know anything about the Gu family, if he lived too close, it would be easy to show flaws, so he specially asked Chang Bo to choose a remote place.

First, it is convenient for him to practice, and second, he can also avoid the various clansmen of the Gu family.

The delicacies had already been prepared in the wing, and after Gu Xiuyun had a full meal, he drank the medicinal soup in front of him.

"It's really worthy of the Gu family, there is an endless supply of elixirs every day, just with the medicinal power accumulated by these elixirs, it is worth half of the demon blood!" Carefully sensing the movement in his spine, Gu Xiuyun sighed in his heart.

Shortly before his reincarnation, the original owner of the physical body had just tried to ignite the spiritual vein, although he failed to rush through the level, but the medicinal power in his body had accumulated a lot, coupled with the supply of elixir for nearly a month, there were faint signs of spiritual vein condensation in his vertebrae.

Of course, if you really want to condense the pseudo-spiritual vein, you need at least five parts of the medicinal power of demon blood, after all, the power of the elixir is loose, and if you want to condense the real spiritual vein, you need far more medicinal power than demon blood.

It is better to use the elixir to ignite the spiritual vein, it is better to be safe, and you can try it again and again, but the cost is far greater.

Although the Gu clan is powerful, it can only supply the descendants under the age of twenty, and even Gu Xiudan and the others are not qualified to take it anymore.

"These medicinal powers can't be wasted, let's refine them into true qi!"

Gu Xiuyun sat down cross-legged, his true qi circulating endlessly in the meridians, slowly refining the medicinal power in his flesh and blood, and enhancing his own strength.

If others see it, they will definitely reprimand him for destroying the heavens, the elixir can enhance the power, but the true qi cannot be converted into the spiritual power, he does this, it is undoubtedly a sacrifice of the roots.

But Gu Xiuyun had other plans in his heart.

Although the elixir is less dangerous to condense the spiritual vein, it takes a long time, and you have to take it for at least three years before you can try to ignite the spiritual vein.

If the ignition fails, you will have to endure it for another three years.

But he only has two years left in his life, how can he have time to slowly survive?

The only way is to use demon blood to ignite the spiritual veins.

......

Half a day later, Changbo's voice came into the chamber, "Childe, the martial arts masters you asked your wife to help you search for a few days ago have sent two more, do you want to see them?"

"Let them in!" Gu Xiuyun opened his eyes, his eyes shining brightly.

After half a day of cultivation, his skill has increased a bit, based on the elixir, the potential of this physical body is much greater than that of his previous life, and the true qi that the dantian can withstand is at least twice as much.

"Maybe it's because I've experienced two spiritual veins, and although I failed to rush through the level, my physical body has also strengthened a lot!" Gu Xiuyun said to himself secretly.

Bang dang!

The wooden door opened, and two old-looking warriors walked in.

"The villain has seen Yun Gongzi. ”

"Since you agreed to come here, you should know what I'm going to do, right?" Gu Xiuyun looked at the two old men, "I want to take your strength and refine your physical body, once this method is used, the power in your body will be cut off by at least half, are you really willing?"

"Madame has given us a thousand taels of gold, and told the two of us that whatever the prince commands, we must obey the orders," the two of them said in unison, "even if they die, they must not resist." ”

"Good. Gu Xiuyun nodded slightly.

These two people look to be at least eighty years old, and their penance skills can be described as the peak, but because of the limitations of their dantian, they can't go further.

They are now old, and their muscles and bones are becoming more and more fragile, even if they have the strength, they can't hunt fierce beasts outside the city, so they agreed to Mrs. Yu's request without hesitation.

In exchange for a thousand taels of gold, it is definitely a good deal.

"You come first," Gu Xiuyun pointed to one of the old men, "Slowly inject your true qi into my body, remember, it must be infused with soft energy." ”

"The villain understands. ”

The old man stepped forward and exchanged palms with Gu Xiuyun, and the mellow true qi was injected into his veins like flowing water.

"The Secret Method of Transforming Gong!"

Gu Xiuyun immediately operated the Heavenly Mandate Clan's secret technique, and the flowing true qi seemed to have been refined, transformed into pure true qi, walked around his body, and returned to the old man's body.

The old man was shocked, and before he could ask, Gu Xiuyun spoke again: "Don't panic, infuse me with all the true qi in your body." ”

"Yes, Childe. ”

The old man sank down and continued to convey the true qi in the dantian, and finally, the old man's own true qi was all exhausted, and only half of the pure true qi remained in his body after being refined.

At this moment, a burst of suction came, and the pure true qi was like a hundred rivers returning to the stream, merging into Gu Xiuyun's dantian and disappearing.

"Whew!"

The two of them separated their palms, Gu Xiuyun stood up, the true qi in his body was as vast as a wave, almost no weaker than when he was at the peak of his previous life!

To make such great progress, it can only be said that the true qi in the old man's body is too majestic, even Gu Yuncong is far from being able to compare, the spiritual energy in this world is already abundant, plus there are groups of demon beasts, and the elixir is everywhere, and the cultivation of martial artists is much easier.

The old man has been practicing hard all his life, and his skills for more than eighty years are almost equivalent to two Gu Yuncong.

Gu Xiuyun felt the majestic true qi in his body, and he was full of spirit, while the old man turned pale and closed his eyes to breathe.

With this action, not only was his true qi in his body exhausted, but his dantian was also seriously injured because of the storage of outsiders' true qi, even if he practiced hard day and night, his strength might only be restored to half of his previous strength.

"Thank you, sir. Gu Xiuyun bowed.

"Childe doesn't have to be polite, the villain also got a thousand taels of gold, and he didn't suffer. The old man replied.

Gu Xiuyun nodded slightly, a thousand taels of gold was enough to buy a small courtyard, which was indeed a huge fortune for the civilians in Youning City.

After a while, Gu Xiuyun and another old man exchanged palms against each other and began the second round of transmission......

Unconsciously, three hours had passed, and the two old men walked out of the room, their faces a little pale.

"Unexpectedly, after swallowing the power of the two of them, my dantian has reached the extreme. Gu Xiuyun frowned.

It's not that his dantian is not strong enough, it's that the true qi of the two old men is too majestic, and now the true qi in his body is almost condensed into mist, and if he slaps it with one palm at will, he can shatter a large area of green bamboo.

"Now that my skill has reached the extreme, I should also consider igniting the spiritual vein, but the spiritual veins are divided into three, six, nine and so on, which one should I choose?" Gu Xiuyun weighed in his heart.

In his previous life, after he ignited the spiritual vein, he keenly discovered that the purer the spiritual vein, the greater the power, so he respected the monochrome vein.

Now that he has flipped through the classics of the Danjing Tower, he knows that the spiritual veins in the world are divided into five grades and four colors.

The first and second of these are both monochromatic veins.

The first-class spiritual vein is the purple qi spiritual vein.

Only take that wisp of Chaoyang purple qi as the foundation of the spiritual vein, this vein has the strongest power and the highest potential, but the daily morning sun is only half an hour, and it is too late to ignite the spiritual vein, only those who are born with spiritual veins can do it.

The second level is the Rihui Spiritual Vein and the Caixia Spiritual Vein, the two are equal, and the spiritual power of the Rihui Spiritual Vein is blazing, so as to practice the fire attribute exercises, the power is multiplied.

The Caixia spiritual vein blends the essence of the sun and the moon, which is the most neutral and mellow, no matter what kind of exercise, it will not conflict.

The third level is the two-color vein and the moonlight spirit vein.

The spiritual power of the two-color vein is not pure, and it has a great impact on cultivation, and the grade is naturally not high.

Although the Yuehua spiritual vein is a monochromatic vein, the power of Yuehua is congenitally weak, and it is inherently inferior to the spiritual power of the sun.

As for the fourth and fifth grades, they are the three-color veins and the four-color veins, and in the Danjing Tower, this kind of veins are also called waste veins.

Now that Gu Xiuyun knows the difference between the fifth-grade and four-color veins, he naturally won't repeat the mistakes of his previous life, and for him, the best choice is the Sunglow Spirit Vein.
