Chu Tianfeng practiced on the top of the mountain for a long time, and after roughly getting used to the sound of the qin, he wandered around the top of the mountain, trying to find the source of the sound of the qin.

However, he searched for a while, but he didn't have a clue.

The sound of the piano was heard clearly outside every building, but when you walked into the building and closed the door, you couldn't hear anything.

Most of those buildings are low-grade artifacts, their defensive formations are low-grade protective arrays, and the gate is engraved with a formation map as a formation flag, even if it is not a divine array master, as long as it is cultivated to a deep level, it can be easily opened or closed.

Although Chu Tianfeng's cultivation is not high, it will be enough to deal with the lower-grade protection array, and it will only take some effort.

Therefore, he searched one building after another, and tried one building after another, but unfortunately, the result was disappointed again and again.

At dusk on the tenth day, when the remnant sun was gone, Chu Tianfeng came to the last and highest building.

This building is located at the highest point on the top of the mountain, although it is also three floors, but each floor is very high, about nine meters or so, this is not the point, the point is that this building is a high-grade artifact!

There are four doors in total, two are closed, two are hidden, Chu Tianfeng secretly rejoiced, released his divine sense and swept it, "seeing" that it was empty, only some columns and the like, so he walked in lightly.

The interior looks very large, about more than a thousand square meters, and there is a boxy staircase in the middle, Chu Tianfeng swept it with his divine sense, but "saw" that in addition to the three floors above ground, this building also has a basement, and there are as many as nine floors!

Chu Tianfeng walked up the stairs first, and found that the internal structure of this building was similar to that of the Tongtian Palace, there was a hall on each floor, and the hall was empty, oh no, there were some columns, outside the columns, there were still columns.

Of course, these columns, as well as the doors, windows, and walls of the building, are engraved with array diagrams, that is, the defensive arrays of the entire artifact house.

Chu Tianfeng swept layer by layer, but failed, so he had to turn around and go downstairs and enter the basement.

The structure of the basement floor is similar to the upper structure, and when you come out of the stairwell, you will see a large hall in front of you, but its area seems to be smaller than the top, only a few hundred square meters, and the walls are also carved with a pattern.

Chu Tianfeng swept over it carefully, and found that these formations were not exactly the defensive formations of the entire building, some of the formations were self-contained, and they were lower-grade protective formations, and some of their peripheral shapes were larger, like a stone door, and some were smaller, like a niche.

There is no doubt that there is something else in these inferior protection array diagrams!

Chu Tianfeng was overjoyed, and immediately took out the divine sword, facing one of the niches, and the sword qi roared out.

The formation of the niche was weaker than the ordinary formation of the same level, and in less than a day, it was broken with a bang.

However, there was only one word in the alcove, uh, empty!

Chu Tianfeng did not give up, and turned to attack other niches.

The second, empty, the third, empty, the fourth, is empty......

Chu Tianfeng attacked for more than ten days in a row, opened more than a dozen niches, and still found nothing, so in desperation, he had to change his target and attack those gate-shaped protective formations.

In this hall, there are a total of five door-type arrays, each door is engraved with patterns, in turn for the long sword, Dan furnace, iron hammer, talisman, array diagram, Chu Tianfeng is not a rookie, at a glance, these five patterns represent the five aspects of fighting methods, alchemy, refining, talisman making and array.

Chu Tianfeng was born as a formation mage, and he was first attracted by the formation map engraved with the formation map, and after studying it carefully, he found that it was the formation map of the Nine Formation Breaking Formation Banners.

These arrays are all divine array diagrams, which are very different from immortal arrays, their spatial rules are more complex, and the array diagrams are also ever-changing, often in a line, the divine element has changed several times, constituting several degrees of space.

Chu Tianfeng originally wanted to study the Divine Array Diagram so that he could become a Divine Array Master in the future, but he was worried that there would not be enough time, this Eight Sound Valley Ruins would only be opened for three years at a time, and once he missed it, he might not be able to go out of the formation.

Therefore, he still used the old method, directly took out the divine sword, and attacked with sword qi.

Boom! Boom!

The sword qi was like a rainbow, and it slammed into the protective array one after another.

The protective array is the same as the niche protective array, it is also a low-grade protective array, under the rapid attack of the sword qi, in less than a day, it collapsed with a bang, and the stone gate also opened with a bang.

Chu Tianfeng's divine sense swept away, but he "saw" that there was a stone room inside, about a dozen square meters, and there was nothing else in the room, only a pile of jade slips.

These jade slips are also artifacts, stacked messily on the ground, looking messy.

Chu Tianfeng picked up a jade slip and swept it slightly, "See" is the edict of the inferior god array formation, including concealment, defense, attack, teleportation, etc., and the edict is very detailed, specific to the performance of the material and the refining process.

The biggest difference between the Divine Array and the Immortal Array is the use of space rules, and the Jade Slip analyzes this point very well, comparing the similarities and differences between the two one by one, and elaborating on the layout and cracking skills.

Chu Tianfeng is a superb immortal array master, plus he has studied in front of the space passage in the Tongtian Temple for many years, and he also has a deep understanding of the spatial rules of the divine realm, and many things can be understood at one point.

Subsequently, Chu Tianfeng picked up other jade slips and checked them one by one, but "saw" that they were all inferior divine array formation edicts, but they were just from the hands of different people.

After that, Chu Tianfeng cultivated for a month, and the Divine Yuan was fully recovered, and then he turned to the door-shaped protective array engraved with the Dan furnace, and attacked like a storm to break through the protective array.

As expected, there was also a small stone room in front of him, and there were also a lot of jade slips inside.

These jade slips are all about alchemy or Dan Dao, all of which are the lowest level of lower-grade divine pills, such as Chu Yuan Dan, etc., including the composition and properties of various materials, etc., no matter how big or small, there are full and detailed discussions.

As for the other three gate-type protection arrays, Chu Tianfeng guessed that they must be related to refining, fighting methods and talisman making, so he didn't bother to ask, his body shook and he moved to the second underground floor.

The layout of the second basement floor is exactly the same as that of the basement floor, and it is also a hall, surrounded by some large and small niches, as well as five stone gates, five stone doors engraved with long swords, Dan furnaces, iron hammers, talismans, and array diagrams.

Chu Tianfeng first broke through a niche, and seeing that there was still nothing in the niche, he immediately changed to attack the gate-shaped protective array engraved with a formation diagram.

The moment the stone door opened, there was a bang, and a large piece of jade slips was blown up by the wind, like fallen leaves.

This time, it's still the formation jade Jane!

It is still a low-grade god formation, but it is a composite formation, such as the combination of concealment formation and protection formation, the combination of concealment formation and killing formation, the combination of killing array and killing array, and so on.

Then, Chu Tianfeng turned to attack the gate-shaped protective array engraved with the Dan furnace.

No surprise, it turned out to be a lot of jade slips, Dan Dao jade slips.

The difference is that this time the Divine Pill has been upgraded, but it is still a low-grade Divine Pill, such as the Illusory Divine Pill, the Illusory Yuan Pill and other cultivation Divine Pills, as well as the auxiliary Divine Pills of the same level, the Healing Divine Pill, and so on.

Since then, Chu Tianfeng has searched layer by layer, layer by layer.

The content of the jade slips in those stone chambers is more complex than the first layer, such as the formation jade slips, the first to third layers are the lower grade formations, the fourth to sixth layers are the middle grade formations, and the seven layers and more are the upper grade formations. Each three layers are divided into a single formation, a compound formation, a triple formation, and so on.

Dandao Yujian is also roughly the same, the first to third layers are the lower grade divine pills, the fourth to sixth floors are the middle grade divine pills, and the seven layers and above are the upper grade divine pills.

Chu Tianfeng was full of energy, and it took him more than half a month to reach the ninth layer.

The ninth floor is basically the same as the upper eight floors, except that there is an extra rudder-like thing in the hall, which is connected to the building, and there is a faint sound of the piano coming from the inside, which must be the source of the piano sound.

Chu Tianfeng didn't have time to take a closer look, and ran straight to the stone gate marked with the formation map, and attacked sharply, breaking through the protective array.

With a bang, the stone gate retreated open, and a large number of jade slips flew up.

Chu Tianfeng released his divine sense as usual, checking one by one.

The first piece, the triple high-grade formation edict, the second piece, the triple top-grade array edict, and the third piece, or the triple top-grade array edict......

Chu Tianfeng checked thirty-one pieces in a row, and when he reached the thirty-second piece, his divine consciousness had just been imprinted, and suddenly, with a bang, his divine consciousness spread sharply to all sides, and the top of the mountain, the main hall, the medicine garden, the narrow valley, the entrance of the Eight Sound Valley, etc., were instantly in full view!

Needless to say, this is the Broken Array Jade Jane, the Broken Array Jade Jane of the Eight Sound Valley!

Chu Tianfeng was overjoyed, and hurriedly took out a thin thread of spider silk, tied the broken array jade slip, and solemnly hung it around his waist.

Previously, he was also worried that when the ruins were closed, Xiliujin's father and daughter would wait for him at the entrance, and he had been entangled for a long time about this, thinking of many ways, and even planned to take the initiative to hand over a few furnaces of divine spirit grass to Xiliujin.

Now, with this jade slip, he no longer has to worry about this problem, he even wants to stay in the Eight Sound Valley to cultivate without going out after the ruins are closed.

There is plenty of spiritual energy here, and there is no great power, it is simply a good place to cultivate!

Thank God! Thank you to the Valley of Eight Sounds! Oh, I have to thank Miss Si Li, the precious daughter of Xiliujin, if it weren't for this fat girl who gave him a place in Yujian, he wouldn't have been able to get in!

Chu Tianfeng was so excited that he immediately drilled into the Heavenly Dzi, told Feng Mingxue, Long Fei and others the news, and asked for their opinions.

"Haha! I agree!" Long Fei was the first to agree.

"I also agree, as long as the ruins are closed, this is our world!" Feng Mingxue raised his hand second.

"That's right! Xiao Yunmeng was the third to agree.

．．．．．．

Chu Tianfeng raised his hands slightly, and said loudly: "Since this is the case, then we have decided to cultivate here for a period of time before leaving." ”

He thought that he would at least become a low-grade Divine Pill Master, and if possible, strive to break through to the tenth layer of the Illusory God in one fell swoop!

"Hehe, hey, you'd better let us out early!" Long Fei rubbed his hands together, "I'm about to suffocate to death if I stay here every day." ”

"That's it, why don't you take us out to have a look now?" Feng Mingxue listened to the wind is rain, and pulled up Chu Tianfeng.

Chu Tianfeng was embarrassed, so he had to tell them about the situation of the Eight Music Valley Hall, especially the terrifying sound of the piano, and let them wait for a while.

Feng Mingxue and the others felt helpless, so they had to reluctantly agree.
