"Thank you so much, Master Dugu!"

Ling Feng bowed slightly to Dugu Yu's father's father. Now Dugu Yu's father is the head of the Dugu family.

Ling Feng did not take back the jade slip because there were restrictions left by him on the jade slip, and he was not worried about people from the Dugu family checking the content behind it.

"Master Qin Xiao, let's go!"

Seeing that Ling Feng and his father had reached a deal, Dugu Yu was also very happy. He took the big seal in front of him in his hand.

Because when he helped Ling Feng, he also helped his own family. For him, this was the best of both worlds.

After all, this time he got back a heaven-defying sword technique for his family.

Their family has inherited it for hundreds of thousands of years, and they have only obtained five complete heaven-defying sword techniques, but now they have one more.

Ling Feng and the red snake girl followed Dugu Yu and left the hall.

"Hahaha, I didn't expect Xiaoyu to be able to get back a heaven-defying sword technique for our Dugu family!"

"This sword technique is not only complete, but also has a very low threshold for practice. It is suitable for most disciples of our Dugu family to practice!"

"And the inheritance on this jade slip can be activated at least a thousand times!"

Duguyu's father and the other two sages were very satisfied.

Ling Feng just used the Heaven-defying Sword Technique to exchange with them to enter the scripture library of their Dugu family to check out the Qi Refining Technique.

And it's still unclear whether Ling Feng can find the right Qi refining technique for him.

For the members of the Dugu family, this is definitely a business that is sure to make a profit without losing any money.

Because not everyone can get close to the advanced Qi Refining Techniques in their family scripture building.

Only those who meet the qualifications can obtain the inheritance of the Qi Refining Technique.

If Ling Feng cannot obtain the inheritance of those advanced Qi refining techniques, there is nothing they can do.

Half an hour later, Dugu Yu led Ling Feng into the space where the Dugu family kept the Qi Refining Technique.

The red snake girl did not come with him. He was arranged by Dugu Yu to live in a luxurious courtyard, where he was provided with a large amount of delicious food and asked to wait for Ling Feng.

Red Snake Girl was very satisfied with this arrangement with Dugu Yu.

The Qi Refining Techniques in this space are also in the same layout as the Qi Refining Techniques in Dan Pavilion. These Qi Refining Techniques are all wrapped in bubbles.

Those in the outer areas of the space are low-level Qi Refining Techniques, while those deep in this space are high-level Qi Refining Techniques.

Dugu Yu held a big seal in his hand and put a mark on Ling Feng's hands.

As long as Lingfeng presses the mark on the palm of his hand on the bubble, he can obtain the Qi Refining Technique sealed in the bubble.

Ling Feng took Dugu Yu and flew directly towards the depths of the book collection space.

His first target is those heaven-defying Qi Refining Techniques.

In the core of the Dugu family's book collection space, Lingfeng saw thirty-seven special items sealed by nine-color bubbles.

Ling Feng knew that these special items must contain treasures containing heaven-defying Qi Refining Techniques.

Because the Heaven-defying Qi Refining Technique is not allowed by Heaven, special things are needed to carry it.

"So many heaven-defying qi refining techniques?"

When Ling Feng saw these nine-color bubbles, he was a little surprised.

"The Qi Refining Techniques in these nine-color bubbles are all heaven-defying Qi Refining Techniques, but only five of the Qi Refining Techniques are complete, and the others are incomplete!"

Dugu Yu opened his mouth and explained to Ling Feng.

If their family really had that many complete heaven-defying Qi Refining Techniques, they would be rich.

"Five complete ones, that's a lot!"

Ling Feng smiled, and then flew towards those nine-colored bubbles. The most important thing he wanted to find these Qi Refining Techniques was to fuse them together to complete his Hunyuan Qi Refining Technique.

Therefore, he does not have very high requirements on whether these Qi Refining Techniques are complete or not.

He began to use the marks in his hands to burst the bubbles and get all the Qi Refining Techniques contained in those special items.

Among those incomplete Qi Refining Techniques, some only have the front part, some only have the middle part, and some only have the back part.

Ling Feng accepted all these Qi refining techniques without fail.

Three hours later, Ling Feng came out of the Dugu family's scripture library.

He obtained a total of five complete Heaven-defying Qi Refining Techniques in the Poisonous Gu Family's Sutra Collection Building, of which one was advanced, two were intermediate, and two were elementary.

In addition, he also obtained thirty-two incomplete heaven-defying Qi Refining Techniques and more than 800 Heaven-level Qi Refining Techniques.

"Master Qin Xiao, have you found an advanced Qi Refining Technique suitable for your practice?"

Coming out of the Scripture Collection Building, Dugu Yu asked Ling Feng.

"Not yet, we have to keep looking!"

Ling Feng shook his head slightly. He knew that even if he refined all the Qi Refining Techniques he obtained today, he would definitely not be able to complete all the nine levels of Hunyuan Qi Refining Techniques.

Therefore, he still needs to obtain more Qi Refining Techniques.

After burning the incense, Dugu Yu took Ling Feng back to the main hall where the three sages of the Dugu family met with Ling Feng.

At this moment, only Duguyu's father was in the hall, and neither Lord Hongjian nor Lord Yujian were there.

"Master Qin Xiao, have you found a suitable Qi refining technique?"

After seeing Ling Feng, Dugu Yu's father immediately asked.

Ling Feng shook his head slightly and said: "Not yet, I'm afraid I have to continue to look for it. Head of the Dugu family, give me the jade slip and I will open the forbidden seal on it!"

"good!"

Duguyu's father nodded, then took out the jade slip that Ling Feng had given him before, wrapped it with a gentle force, and sent it to Ling Feng.

Ling Feng held the jade slip, unlocked the restrictions he left on the jade slip, and then handed the jade slip to Dugu Yu beside him.

Dugu Yu took the jade slip and brought it to his father, Dugu Fan.

Dugu Fan took the jade slip and examined it with his spiritual sense. He found that the seals on the jade slip had been unlocked and he could see the complete sword formula.

After seeing this complete sword art, he was very happy. The latter part of this sword art was even more amazing than the front part.

"Master Dugu, if there are no problems, then I will leave!"

Ling Feng opened his mouth and told Dugu Yu's father that now that he had got what he wanted, he no longer wanted to waste time with the Dugu family.

He wanted to go to Wenshi Pavilion's headquarters to see if he could get some advanced Qi-refining techniques in the Sutra Collection Building at Wenshi Pavilion's headquarters.

Ling Feng's previous plan was to come to the Central Territory to find Nangong Ziyue. He wanted to see if Nangong Ziyue could let the powerful people of the Nangong family help the sloppy old man refine the magic weapon.

But now he has changed his mind. He should solve his own cultivation problems first.

The headquarters of Wenshi Pavilion is not in Tianjian City, but in the source world of Wenshi Pavilion.

The Heavenly Pattern Source Realm is where the headquarters of Pattern Master Pavilion is located.

And many of the techniques and treasures of Wenshi Pavilion are in the library of Tianwenyuan Realm.

If Lingfeng wants to obtain the Qi Refining Technique of Wenshi Pavilion, he must go to the headquarters of Wenshi Pavilion in person.

Moreover, this time, Ling Feng also planned to go to the headquarters of the Pattern Master Pavilion to conduct the assessment of the eighth-grade pattern interpreter.

Because of the eighth-grade tattoo master, only the headquarters of the Tattoo Master Pavilion is qualified to conduct the assessment.

All eighth-grade tattoo masters of the human race are assessed at the headquarters of the Tattoo Master Pavilion.

Ling Feng found the Red Snake Girl and took the Red Snake Girl to the Wenshi Pavilion in Tianjian City.

In the Pattern Master Pavilion of Tianjian City, there is a flying boat that goes to the source world of Heavenly Patterns.

Moreover, as Lingfeng's seventh-level pattern solver, he can take two people on these flying boats for free.
