Ye Wudao became interested and looked carefully.

"Next is the formation of the eternal late stage, the Nine Dragons Royal Mountain Formation. This formation covers a huge area and can protect the mountain gate and block the attack of two or three eternal late cultivators. It is difficult to crack... The starting price is 30,000 chaotic crystals! "

"Thirty traps in the ground. When this trap is set up, thirty round traps with a diameter of 100 meters can be formed within a radius of ten miles. If you enter in the later stage of eternity, you will be trapped for a while, but... the starting price , 10,000 Chaos Crystals!"

"The cold solid formation..."

The formations in the front are more expensive, they are all defense formations, and there are also killing formations in the back, but the price is relatively low.

Ye Wudao was extremely curious, and asked Elder Wang: "Why are the mountain protection formations more expensive than the killing formations? Some killing formations are stronger than the protection formations."

Elder Wang explained: "The reason why most of the protective formations are precious is that no one wants their sect's formation to be deciphered. Ordinary mountain protection formations will not appear in the auction house."

Elder Wang said: "Ordinary mountain protection formations can be purchased from the outside world, but after all, there are too many, so there is a way to crack them, but the mountain protection formations in the auction house are not so simple."

"Even if it is an ordinary formation from the outside world, if it is placed here, the strong one who sells it will carefully repair it so that it will not be easily cracked, and the security is very high."

Ye Wudao was curious: "How many chaotic crystals are needed in the outside world for the mountain protection formation in the later stage of eternity, I mean the ordinary one."

"You can buy a good finished product with a few hundred chaotic crystals." Elder Wang said: "However, the formation here will be explained in a book, which means that the formation is completely entrusted to you, so you can rest assured."

Ye Wudao understood that buying the formation here is equivalent to buying the experience of building this formation, and it is also beneficial to practice the formation.

It's just... still too expensive!

If Ye Wudao hadn't happened to meet Elder Wang and earned 150,000 chaotic crystals, he might not even have the qualifications to bid.

Ye Wudao was not interested in the formation in the later stage of eternity. What he was interested in was the semi-emperor formation, so after waiting for a long time, he finally reached the final stage.

"Everyone." Only Liu Keqing said in a strong voice: "Next is the Banhuang Formation. The formation of mountain protection and boundary protection has complex functions."

"This set of formations is a multi-polar half-emperor. It is self-improved according to the trajectories of the stars. The maximum coverage of the formation can be a million miles, and the minimum can be ten miles."

"If the coverage area is larger, the power will naturally decrease, but there are many changes in it. The formation can be reduced and condensed within a few breaths, and it can resist several full-force magical powers of a multi-polar half-emperor!"

"Moreover, it is fully functional, capable of self-destructing, and transforming into a killing formation, but its power will be much weaker..."

After Elder Wang talked for a long time, Ye Wudao finally understood that this set of formations is mainly because of its high flexibility and strong effect, so it can be regarded as a treasure.

Through the formation book, the function of the formation can also be changed, and even the strong who lack the experience of the formation can use it.

Isn't this exactly Ye Wudao's favorite thing?

Liu Keqing continued: "This is something that the multi-polar half-emperor temporarily handed over to this auction house for sale, so the starting price is very low, starting at 10,000 chaotic crystals."

Just as Ye Wudao was about to speak, he heard shouts from all around him.

"Thirty thousand Chaos Crystals!"

"fifty thousand!"

"Seventy thousand!"

Ye Wudao was stunned for a while, his face was a little ugly, it seems that many people still value this semi-emperor formation, and it is not so easy to buy it. JrNovels.com
