When he first met Dugu Yu, it was in Tianying Xuanjie.

At that time, he and Dugu Yu were both in the innate perfection state, and neither of them could condense the Nascent Soul.

The second time he met Dugu Yu was on Thousand Sword Island in Tianjian City. At that time, Dugu Yu had a sword fight with Ximen Wuhen, the Third Saint Son of Penglai Pavilion.

At that time, he was at the ninth level of the soul.

But now, Duguyu's cultivation has reached the ninth level of Daojun, and he is the second level of Daojun.

The cultivation between him and Dugu Yu was greatly reduced.

"It's all the fault of the Dan Pavilion people!"

Ling Feng cursed secretly. He was trapped in the Bahuang Soul Refining Tower space for a year. Although his strength continued to improve during this year, his cultivation level had stagnated.

In the realm of Half-foot-step.

However, Ling Feng also knew that the reason for his slow improvement in cultivation was because his foundation building platform and Yuan Shen were too advanced, and his current Qi Refining Technique did not reach a level that matched his Yuan Shen level. This resulted in

His cultivation level improved slowly.

"My Qi Refining Technique is still not advanced enough. I have to find a way to complete the rest of the Hunyuan Qi Refining Technique!"

Ling Feng thought secretly in his heart.

According to his situation, he must use the seventh level of Hunyuan Qi Refining Technique at this moment to fully unleash his potential.

If he cannot complete the subsequent Qi Refining Techniques, then when his cultivation reaches Tao Ancestor, the speed of improvement will definitely be slower. It may take several years, or even more than ten years, to reach a small level.

This kind of speed of improvement is intolerable to Ling Feng.

Although there is still room for improvement in his Hunyuan Body Refining Technique, after all, the nine levels of Hunyuan Body Refining Technique are in full order, so it has little impact on Ling Feng.

However, of the Hunyuan Qi Refining Technique he obtained from Xue Wuji, only four levels were complete, and only half of the fifth level was obtained. The remaining four and a half levels were taken away by people from the Yu family in the Holy Land of Yutian Sect.

There was no way he could get the remaining four and a half levels of Hunyuan Qi Refining Technique from the Yu family.

Fortunately, with the help of soul liquid, he can integrate other Qi Refining Techniques by himself, and finally complete the Hunyuan Qi Refining Technique.

If he didn't have a large amount of soul liquid to squander, he wouldn't be able to complete such a feat as the fusion of body refining techniques, because the fusion technique would consume a lot of soul power.

Even those powerful people would not dare to do this.

The next day, Dugu Yu took the disciples from the Tianjian Sect and boarded the ninth-grade battle boat they had arrived from.

Ling Feng and Red Snake Girl also followed.

This ninth-grade war boat can resist the attacks of powerful people.

Only the power of those who surpass the mighty can break through the defense of this battle boat.

However, if those powerful people use this level of power to destroy the war boat, they will definitely attract Tiannu.

Therefore, the safety factor of this ninth-grade battle boat is very high.

Ling Feng and the red snake girl were arranged by Dugu Yu into a spacious cabin.

After boarding the war boat, Ling Feng found Dugu Yu.

"Master Qin Xiao, what's wrong?"

Duguyu asked Lingfeng with respect.

"I want to develop some qi-refining techniques, at least those above the heaven level. If there are qi-refining techniques that defy the heavens, it would be better. Do you have any ideas?"

Ling Feng told Dugu Yu his thoughts.

He knew that Dugu Yu was the Holy Son of Tianjian Sect, with a transcendent status and great influence.

If he collects Qi Refining Techniques for himself, it might save him a lot of trouble.

"That's okay, but the price of the heaven-level Qi-refining art is very high. A complete heaven-level primary Qi-refining art is worth at least 50,000 source stones, the intermediate-level one is worth 150,000 source stones, and the advanced one is worth 50,000.

One hundred thousand Origin Stones, and those at the top of the Heavenly Rank are one million Origin Stones!"

"And the heaven-defying level Qi Refining Technique is almost difficult to obtain with money. Even if it is available, even if it is a heaven-defying elementary level, it will require at least tens of millions of source stones!"

Although Dugu Yu didn't know why Lingfeng wanted to collect these Qi Refining Techniques in large quantities, he knew that these Qi Refining Techniques and those techniques were the most valued treasures by all the major forces.

"So expensive?"

After hearing the prices Dugu Yu said, Ling Feng raised his eyebrows slightly.

He didn't expect these skills to be so valuable.

"right!"

Dugu Yu nodded slightly!

"It seems that if I want to buy Qi Refining Techniques, this method won't work. I want to complete the remaining Qi Refining Techniques. I don't know how many Heaven-defying Qi Refining Techniques are needed. If I use all the Heavenly Qi Refining Techniques

If so, the number will probably be even more!”

Ling Feng was thinking, and then said to Dugu Yu: "No matter what, please help me pay attention first. If there is a Heavenly Level Qi Refining Technique, go to Wenshi Pavilion and send me a message!"

"Master Qin Xiao, you are a tattoo master. You can definitely go to the library of Tattoo Master Pavilion to check it out. As a seventh-grade tattoo master, you can check out the Qi Refining Techniques in Tattoo Master Pavilion and enjoy a very high discount.

!”

Dugu Yu opened his mouth and said to Ling Feng.

"Well, this is not a bad idea!"

Ling Feng nodded, and then asked Dugu Yu: "Can you go back and discuss with your family members and let me enter your Tianjian Sect's library to check it out? I want to find a Qi refining method that is more suitable for me.

Art, in exchange, I can give you Tianjian Sect a heaven-defying sword art!"

"A heaven-defying sword art?"

A look of surprise appeared on Dugu Yu's face. Their Tianjian Sect didn't have many heaven-defying sword techniques, only five in total.

The most famous among them is Tianjian.

The Heavenly Sword is the inherited sword art of their Heavenly Sword Sect. It is the most powerful and has the lowest training threshold. Even the innately powerful can practice it.

The other four Heaven-defying Sword Techniques have extremely demanding cultivation conditions, and only a very small number of people can practice them.

Their Heavenly Sword Sect has been inherited for more than 150,000 years from the ancient times to the present, and has accumulated five complete Heaven-defying Sword Techniques.

As for those incomplete Heaven-defying Sword Techniques, their Heavenly Sword Sect has quite a few, but those incomplete Heaven-Defying Sword Techniques are not as valuable as a complete Heaven-Level Peak Sword Technique.

"Is the Heaven-defying Sword Technique you gave me complete?"

After Dugu Yu came to his senses, he asked Ling Feng.

"Yes, absolutely complete!"

Ling Feng nodded slightly.

He had obtained seven complete heaven-defying sword techniques on that mysterious island.

The most advanced among them is a sword art with a similar attribute. This sword art with a thunder attribute is an advanced sword art that defies the heavens.

Of the remaining four types, two are heaven-defying intermediate sword techniques, and the remaining four are heaven-defying elementary sword techniques.

When Ling Feng was on Penglai Island, he passed on a heaven-defying elementary sword technique from water and fire fellow practitioners to Ximen Wuhen.

In addition to the Heaven-defying Sword Technique, Ling Feng also received many other Heaven-defying level inheritances on that mysterious island.

Now, it's time for him to use these heaven-defying inheritances to transform things.

Because if he doesn't change it, these heaven-defying inheritances will not be of much use if they remain in his body.

"Okay, I will go back and talk to my family members then. The final decision is in their hands, and I can't guarantee that they will definitely agree!"

Dugu Yu nodded slightly. Although he said so, he knew in his heart that if Ling Feng could really come up with a complete set of heaven-defying sword techniques, then there would be a 90% certainty that the members of his family would agree to Ling Feng's wish.

Require.

Because their Dugu family is a swordsman family, their desire for sword techniques is much stronger than those for Qi refining techniques.

Dugu Yu and Ling Feng chatted for a while, and asked Ling Feng a few small questions, and then he left.
Chapter completed!
