After Su Han saw the bookshelf, his eyes lit up, and a trace of excitement surged in his heart. Those books were obviously the books that this peerless powerhouse read, and they would definitely not be ordinary.

Before Su Han came to the bookshelf, he picked up those books and looked at them one by one. The color of joy on his face grew stronger.

Of the dozen or so books, each one was extremely precious to Su Han. One of the "Luo Taihe Travels" records the geography and character customs of the entire Great Yan Dynasty and the four major empires of the Golden Wolf Empire, the Wuluo Empire, and the Great Xuan Dynasty, as well as a series of surrounding vassal countries and small countries. A book of "Treasures" records the images and functions of various heavenly and earthly treasures between heaven and earth. A "Detailed Explanation of Sects" records the approximate strength and style of the major sects.

Each of these dozen books is extremely precious, among which Su Han values the most are the three "Formation Foundation", "Demon Book" and "Demon Bird Transformation".

Among them, "Formation Basics" teaches some of the most basic formation principles, and also records the formation layout and breaking methods of the most basic formation "Phantom Formation".

The "Demon Classic" is a secret book, which records the eight-grade martial arts "Earth Demon Gong" for demonic cultivation, as well as an eight-grade martial art "Hidden Breath Gong", and a nine-grade martial art "Soul Searching Dafa". Although "Hidden Breath Gong" and "Soul Searching Dafa" are not attack martial arts, they also have very powerful abilities.

The higher a martial artist's cultivation realm, the more vigorous the qi and blood will be, and after cultivating to the true qi realm, even if they don't do anything, there will be a trace of breath flowing out of the pores of their body. That trace of aura is extremely weak, and ordinary people can't feel it at all, but martial arts powerhouses are different.

Cultivating to the Acquired Sevenfold Spiritual Qi Realm, the martial artist's six senses will be greatly strengthened and become extremely acute. At the same time, with the continuous improvement of the cultivation realm, the six senses of the martial artist will also be continuously strengthened. If you cultivate to the innate realm, the martial artist's body will once again gain a terrifying improvement, and the six senses will become more powerful, and you will be able to see through the realm of the innate martial artist at a glance, and at the same time, you will be able to sense the breath of the strong within a radius of fifty meters.

This "Hidden Breath Gong" can allow cultivators to completely conceal their breath, so that their breath will not be exposed at all. After using the Hidden Breath Gong, as long as he doesn't do anything with others, even the innate powerhouse will not be able to see through the cultivator's cultivation, and will only think that this is an ordinary person.

That soul searching Dafa is a terrifying auxiliary magic skill, once it is cast on the enemy, it can search for what you want from the enemy's brain. Of course, there are limits to this magic skill, once it is cast on the enemy, then the enemy will become an idiot, and the caster will also have a headache, if one is accidentally counterattacked, then the strong person who casts this magic skill will become an idiot.

That "Demon Bird Transformation" is a great martial art, this martial art is to collect the blood of the innate demon bird and refine it into the body, cultivate to the Mahayana realm, you can transform into an innate demon bird-like existence, and fly freely in the sky.

When Su Han put away the secret books of the books, he saw a bronze token placed on the bookshelf, he picked up the token and looked at it, only to see that the token was engraved with the three big characters of Gu Yue Ling.

Seeing the three words of the Gu Yue Order, Su Han's heart moved, and a flash of ecstasy flashed in his eyes: "This token, is it the legendary Gu Yue Order?"

In the Great Yan Dynasty, there were three major martial arts holy places, namely Luoshan Sect, Guyue Sect, and Chivalry Gate. Among these three martial arts holy lands, the masters are like clouds, and the strong are like rain. Each martial arts holy land has more than ten innate powerhouses, and in addition to this, there are also alchemists, talismans, refiners and other powerhouses that are rare in the outside world. Each Martial Dao Holy Land possessed the strength to rival the Great Yan Dynasty. Back then, the Great Yan Dynasty was able to overthrow the Great Xia Dynasty entirely because of the help of the three major martial arts holy lands.

The three innate powerhouses in the Great Yan Dynasty are the three major martial arts holy lands sent to protect the royal family of the Great Yan Dynasty, and the masters who protect the entire Great Yan Dynasty.

It is precisely because of this that the status of the three great martial arts holy lands is extremely high in the Great Yan Dynasty, and even the emperor of the Great Yan Dynasty is a head shorter in the face of the three major martial arts holy lands.

This Gu Yue Decree is a reward specially given by the Gu Yue Sect to those who have completed the various difficult tasks issued by the Gu Yue Sect among the three major martial arts holy lands. As long as you enter the Guyue Sect with the Guyue Order in hand, you will be able to ascend to the sky in one step, avoid all kinds of trials, and become the inner disciple of the Guyue Sect.

Once you become an inner disciple of the Guyue Sect, you will be able to cultivate the superior exercises that are rare in the outside world, and if you are not too poorly qualified, you will basically be able to cultivate to the Acquired Sevenfold Spiritual Qi Realm. At the same time, the status of the inner disciples of the Gu Yue Sect was extremely high, and even the Taishou of a county of the Great Yan Dynasty did not dare to be disrespectful to the inner disciples of the Gu Yue Sect.

Any inner disciple who came out of the Three Holy Lands, as long as he joined the Great Yan Dynasty, whether he was in politics or in the army, he would be able to achieve great achievements. Two-thirds of the top generals in the army of the Great Yan Dynasty were strong men from the three major martial arts holy lands.

If this Gu Yue Ling is placed in the auction house, it will definitely be able to be auctioned for more than 500,000 taels of silver, which is extremely precious.

Su Han had this Gu Yue Order, and as long as he went to the Gu Yue Sect, he would be able to become an inner disciple of the Gu Yue Sect. Once he becomes an inner disciple of the Guyue Sect, the Zhao family in Xiyuan Town is nothing at all, and he can be pinched to death at will.

Su Han was very satisfied and put the Gu Yue Order into the ring, took out the "Formation Basics" and flipped to the Phantom Formation chapter to study it carefully. The Phantom Array arranged around this valley is so mysterious that even if a strong person in the Ninefold Grandmaster Realm is trapped in it, one of them will fall if he is not careful.

"I see!" Su Han closed the "Formation Foundation" and strode into the cave, walking towards the corner of the valley.

In a hidden corner of the valley, Su Han turned over a stone, and then pulled out a black array chess piece that was stuck in the ground.

As soon as the black chess piece was pulled out, all the bamboos around Su Han immediately collapsed, and the valley was restored to the cruel scene full of murderous intent and traps and corpses.

This phantom array needs a total of eight array chess, one array eye, Su Han followed the instructions in the book, and collected all the array chess and array eyes hidden in various parts of the valley.

Su Han took the array disk that was used as the eye of the array and looked at it carefully, only to see that in the center of the array plate engraved with many mystical lines, there was a stone that flashed with earthy yellow spiritual light and was somewhat transparent, which was almost exactly the same as the mysterious stone he absorbed and refined in the small river, the only difference was that the color of the spiritual light they emitted was different, and at the same time, the spiritual light of this spiritual stone was also very dim: "This is the spirit stone? So, the stone I absorbed in the river is the spirit stone?"
