The materials required for a mountain protection formation were only two pages, and even Yan Ning felt it was a bit incredible. When Jiang Wujue was setting up the formation, the list of materials was written for more than ten pages, various stone statues, jade artifacts, and even some century-old trees. It took more than a dozen trucks to transport them.

However, after Yan Ning finished reading the first page of the material list, his face changed instantly, and he looked like a frost-beating eggplant.

"Thirty thousand-year-old spiritual trees, three thousand kilograms of extremely cold black iron, ninety-nine pieces of warm fields and warm jade, each piece is the size of a palm?"

Yan Ning shed tears while talking. None of these things is of great value. The point is that even if Yan Ning has money, he may not be able to buy these things. They are completely priceless.

Just like this thousand-year-old spiritual wood, there are very few trees in the world today. Those over a hundred years old are protected by tourist areas as treasures. It is difficult for ordinary people to touch them, but the Baili Xiaofeng is so good that you need thirty trees in one bite.

You should know that spiritual wood is not just an ordinary tree, it must grow in a place with abundant spiritual energy. If you split the trunk with one knife, what flows out is not the sap, but spiritual energy. Only such a tree can be called spiritual wood!

Yan Ning once saw such a spiritual tree in Longhu Mountain. Although that spiritual tree is from a thousand years old, it is just this one in the entire Longhu Mountain, because when the tree grows to a certain age, it is very likely to cause a heavenly disaster. Ninety percent of the trees are struck by lightning and will die directly. Only those who survive by chance can be considered spiritual trees.

Yan Ning may not be able to get all of this thousand-year-old spiritual wood, not to mention the extremely cold black iron that is difficult to meet now, which is a jade that is so expensive that people have fired.

After a rough calculation, Yan Ning recognized the current fact: relying on the little money from selling tea in his tea shop, he couldn't even afford a thousand-year-old spiritual wood.

This is the first time in the three years since the Taoism practice, Yan Ning is worried about money.

Seeing Yan Ning's embarrassing appearance, Baili Xiaofeng couldn't help but touch his chin and said, "Sure enough, these materials are too difficult for you to get them. After all, the master sect had spent a lot of energy back then, so he could only get them all together."

"What should I do?"

"If you can't find the materials I need, you can use similar or lower materials instead, but the corresponding effects will also be lacking. For example, if you replace them with a hundred years, the effect will naturally be less than one tenth of them in the past. You can deal with more than a dozen celestial immortals, but now you can only deal with one or two." Baili Xiaofeng said.

Yan Ning sighed and looked sad, but after becoming a celestial immortal, who would not be a hero? If the Wanren Yanyang Formation can deal with the celestial immortal, it would be equivalent to creating a mountain-protecting celestial immortal. According to the value of the celestial immortal, this little treasure is indeed nothing.

Yan Ning continued to look down. Other materials are not particularly precious. There are many in Wanbaozhai, the Extreme Fire Immortal.

But when he saw the bottom of the second page, Yan Ning felt a pain again.

"A magic weapon of imperial level?"

Yan Ning was the only one who could take action on his body, but the Sumeru Ring was too important to Yan Ning and obviously was not suitable for being the eye of a large array.

The Kunwu Sword is Yan Ning's weapon, and it's even worse.

By doing this, only the Gutian jade talisman that Huangfu Ci gave to Yan Ning and a small low-grade magic weapon could be used.

"Hey, in this way, this Wanren Yanyang Formation may not even be able to deal with the Earth Immortal." Yan Ning sighed deeply.

Baili Xiaofeng smiled and said, "You can't get some things together, which leads to the weakening of the power of the formation, but you can use better ones to replace some things. This way, counteract each other, and maybe it can be saved a little."

"It's okay? Doesn't the formation pay attention to balance and constraints?" Yan Ning raised his eyebrows and said in a little surprised.

"That's the formation in your eyes," Baili Xiaofeng said proudly, "Besides, if anyone can set up that formation, what else should I, Baili Xiaofeng do?"

Yan Ning nodded quickly, completely impressed by Baili Xiaofeng. If Baili Xiaofeng had not known this formation, maybe Yan Ning would have called Jiang Wujue to come back and learn from his master.

The last two materials are actually the most troublesome thing for Yan Ning.

"Ten thousand flying swords above the earth level?"

Yan Ning took a breath of air. Is the small world of the Extreme Fire Earth Immortal a wealthy? Even he has only thousands of magic weapons at the Earth level or above, and there is not even a single spiritual treasure or immortal level!

Where can Yan Ning find ten thousand flying swords above the earth level?

Baili Xiaofeng said: "The quality of the flying sword also determines the power of the formation. If you can take out tens of thousands of flying swords above the heaven level, you have to kneel even if the Immortal King comes!"

"Nonsense, if I had tens of thousands of flying swords above the heaven level, I could kill the Immortal King by myself!" Yan Ning couldn't help but complain.

Baili Xiaofeng patted Yan Ning's shoulder and said, "Mr. Nephew, there is nothing difficult in the world, I'm afraid of those who are interested! I have this introductory book for refining weapons. If you go back and study it carefully, please ask me if you don't understand anything."

Yan Ning looked at the artifact refining classics in his hand and almost couldn't help crying. Is Baili Xiaofeng's attitude trying to make himself refine the flying sword?

"Ten thousand flying swords, what year will it take to be refined?"

"Don't worry, you are a person with a fire source. It may be a bit difficult for others to refine weapons, but for you, the difficulty is not strong. Besides, the flying swords required by the large array only need to meet the grade standards, and they don't need to be too fine. With your ability, you can definitely do it!" Baili Xiaofeng said confidently.

Yan Ning smiled bitterly: "Forget it, let's talk about it later."

Baili Xiaofeng nodded, looked at Yan Ning with a long way to go, then waved his hand and went back to rest.

In this way, Yan Ning was left at the entrance of the tea shop, Huang Long and others had already fallen asleep at this time, and Yihu was practicing in the small world again.

Yan Ning returned to the villa and was bored alone, so he came to the small world.

In the Chiyan Hall, Long Zhu and Long Xi were sitting next to Chen Yunna, one left and one right, while the three of them were sitting on the steps outside the Chiyan Hall, chatting about Yan Ning’s gossip.

"Hey, Yan Ning is in!" Long Xi suddenly covered his mouth.

As soon as he finished speaking, Yan Ning appeared in front of the three of them: "Long Xi, are you talking bad about me again?"

"Hehe, I just want to say it, what can you do to me?" Long Xi said with a shameless face.
