Classics Room.

Among them, it was also a mess, the bookshelves were empty, and there were more than a dozen classics scattered on the ground, almost all of which were broken and missing pages, and they were all classics from the Qi cultivation period, and the good Gongfa immortal books had been looted.

Chu Yan couldn't help but be disappointed when he looked at the scene in front of him, why was this former master so unlucky, and the Dark Mansion was also a thief......

Liu Yueying also entered the classic room, and after looking around, she shook her head, obviously, the things in this classic room were of little value, and she was about to leave, but she saw Chu Yan lying on the bookshelf, knocking left and right, and couldn't help but have some questions: "What are you doing?"

"Maybe the previous owner of this cave house hid some secret book or something in a mysterious place, maybe the switch is on the bookshelf. ”

Chu Yan didn't reply, and continued to beat, saying casually in his mouth.

"Is it possible that the previous master of the cave mansion placed the treasure in such a place that is so easy to guess?"

Liu Yueying said a little disappreciatively, but as soon as her words fell, she listened:

"Click..."

A crisp switch twist sounded on the bookshelf......

"Miss Liu, come and see, there is really a dark grid!"

"How could such a thing really happen!"

Listening to Chu Yan's words, Liu Yueying couldn't help but blush, and where she saw it, the bookshelves had already separated to both sides, and a dark grid appeared on the wall.

Chu Yan opened the door of the dark grid, and a thin book lay in it.

When I looked at it, there were a few big characters scribbled on it, "The Law of Ten Thousand Demon Banner Refining", and when he saw these big characters, Chu Yan couldn't help but be shocked.

Seeing the three words Ten Thousand Demon Flags, Chu Yan couldn't help but think of another Demon Dao treasure 'Ten Thousand Demon Flags', which the old man in black robe had used that day, and its power was huge, and Chu Yan still remembered it vividly.

Ten Thousand Ghost Flags, this is a forbidden treasure, to refine this treasure must be condensed with the soul of ten thousand people, as well as flesh and blood, it is the main magic weapon of some big devils in the Demon Dao.

Because according to common sense, cultivators in the Jindan period are unable to refine magic weapons with machine spirits, but these ten thousand ghost flags have found another way, and those unjust souls are not machine spirits, they can be regarded as magic circles arranged in the flags, although they are only magic weapons, they can contain part of the power of the spirit treasure, so those demon road overhauls would rather make people angry and resentful than refine this strange treasure.

Chu Yan opened the first page of the book, and there were still lines of scribbled and wild handwriting on it:

"Everyone in the world refines ten thousand ghost flags, which makes people angry and resentful, and it is only those stupid x demon cultivators who will come up with a stupid way to absorb people's souls and condense magic weapons......"

The so-called ghost is the soul left behind after death, which means that in order to refine this treasure, it is necessary to kill people. Another key point in refining the Ten Thousand Ghost Banner is the need for unjust souls, the greater the injustice of the soul, the stronger the strength of the soul, and the soul is the soul left by the person who died unjustly, that is to say, you must kill those who have no grievances with you to get such a soul.

Seeing this, Chu Yan couldn't help but sigh secretly, the predecessor who wrote this classic was really an arrogant and arrogant person, and continued to look down:

"Haha, the deity knows that it is impossible for those demon cultivators to not think of replacing human souls with demon souls, but the key is that the power of this soul banner mainly lies in the depth of those soul resentments. No matter how wise the demon beast's spiritual wisdom is compared to that of humans, it is much different, and the resentment is also much smaller, and the power of the refined soul banner will not be strong, and the demon soul is very difficult to preserve, and those stupid x demon cultivators will definitely not be able to think of a solution......!

Seeing this, Chu Yan was completely excited, Ten Thousand Demon Banners, I didn't expect that this senior master would actually study such a refining method for a treasure against the sky.

There was a look of astonishment in Liu Yueying's eyes, I didn't expect this guy's luck to be so good, if the refining method of this Ten Thousand Demon Banner was transmitted to him, I am afraid that it would cause a bloody storm again!
