In this Xuanzong vault, there are a total of three storage rooms, and in the first storage room, all the gold bricks are stacked, and all the gold bricks are laughed at by Lu Yu.

As for the second storage room that Lu Yu entered at this moment, there were things in it, and it had nothing to do with gold bricks, although Lu Yu saw that this storage room was also full of rotten wooden boxes, but what emerged from the broken boxes was not brick-like objects, but scrolls of paintings and thread-bound books.

Obviously, the items stored in this second storage room were the calligraphy and painting classics in the treasury of the Xuanzong Dynasty, however, to Lu Yu's disappointment, the scrolls and books did not bear the erosion of time, and all of them had weathered into charcoal.

After taking out a black charcoal-colored thread-bound book from a broken box under his feet, but crushing it in an instant, Lu Yu knew that these weathered books and scrolls seemed to be completely finished, and they could no longer be read.

Now that they have become garbage, the realist Lu Yu no longer feels sorry for those "black charcoals", he took a big step decisively, stepped on the "black charcoal", and trampled the completely weathered Tang Dynasty classics into crumbs.

The reason why Lu Yu wants to crush all those "black charcoals" is because, as "naïve", he feels that among these "black charcoals", there may be some things that can withstand the years, and those books that can resist weathering are the real "treasures".

Sometimes, God will reward the innocent, when Lu Yu stepped on and kicked in the world of "black charcoal", suddenly, with a crisp sound of "......", his right foot kicked a piece of emerald object with a thick wrist and a long forearm.

"Hmm......" After snorting, Lu Yu, who found the "baby", became excited again, his eyes widened, he held high the iron-tailed arrow with the light source "Qiming Fu", and rushed towards the cyan object with a smile on the corner of his mouth.

After running to the side of the thing, Lu Yu stretched out his right hand, picked it up from the charcoal ash on the ground, and used the hem of his clothes to wipe off the black ash on it.

"Well...... "When the black ash on the cyan item was wiped clean, Lu Yu found that this piece of thing was a rolled up jade slip, this jade slip, tied by gold wire, showed a very stylish look, when Lu Yu turned the jade slip in his hand half a circle, he saw that the jade slip was engraved with three big gold characters with a small seal - "Three Emperor Sutra"!

"I'm going to go like this......" Lu Yu, who saw clearly what the big golden characters on the jade slip were, his entire right hand began to tremble, the reason why Lu Yu was so out of shape was because he had read a lot of Taoist classics and knew what this "Three Emperors Sutra" was.

According to legend, this "Three Emperors Sutra" is written by the Great Immortal Silk and the Three Kingdoms period, and is called "Three Emperors Astronomy" by the people of the time, and it is one of the supreme Taoist scriptures.

Before he ascended to immortality, he passed on the only copy of the supreme divine book "Three Emperors Sutra" to Zheng Yin, and this Zheng Yin was the father-in-law of Ge Hongge Daxian, one of the three great immortals of Taoism.

And before Zheng Yin ascended to immortality, he also passed his collection of "Three Emperors Sutra" to his son-in-law Ge Hong Ge Daxian, and later, Ge Daxian praised the "Three Emperors Sutra" in his book "Hug Puzi" in the "Miscellaneous Responses" and "Reverie Chapter", the book said: Practicing the "Three Emperors Sutra" can avoid disasters, avoid evil ghosts, and eliminate epidemics.

Ge Daxian's "Hug Puzi" also mentions that there are three articles in the "Three Emperors Sutra", namely "The Emperor's Text", "The Emperor's Text" and "The Emperor's Text". What is recorded in the "Dihuang Wen" is the Taoist knowledge of subduing demons and eliminating ghosts; And what is recorded in the "Human Emperor Wen" is the knowledge of alchemy and curing diseases.

Later, Ge Hong Ge Daxian passed on the "Three Emperors Sutra" to his disciples and grandchildren, and because Ge Hong Ge Daxian collected countless peaches and plums all over the world, so, soon, there were many Taoist priests in the world who knew how to "learn from the Three Emperors".

However, compared with the Taoism in the "Earth Emperor Wen" and the alchemy in the "Human Emperor Wen", the world prefers the study of the number of mathematics in the "Emperor Wen", that is, the knowledge of fortune telling, which is the same in any era.

With the departure of Ge Hongge Daxian, the "Three Emperors Scripture" and the "Human Emperor Text" that are not very popular with the common people in the "Three Emperors Scripture" were lost, and gradually, only the "Three Emperors' Scripture" that was circulated in the world became the book of prophecy in the eyes of the people, and it was not much different from ordinary fortune-telling tutorials.

Because the Emperor's Text is full of a large number of methods for predicting the future, its theories can easily be used by the rioters to control the minds of the ignorant people, and then launch riots, so the aspiring monarchs cannot tolerate the existence of the Three Emperors.

So, in the Tang Zhenguan period, Tang Taizong Li Shimin ordered: burn all the "Three Emperors Sutra" in the world, not a single one, and anyone who dares to hide it privately will be punished by bullying the monarch and exterminating the three clans.

In the end, in the twenty years of Zhenguan, as the last so-called "Three Emperors Sutra" was completely burned, the Taoist canon "Three Emperors Sutra", which cultivated the three immortals of Bohe and Zheng Yin Ge Hong, was completely lost.

What Lu Yu could not have imagined was that in the Great Song Dynasty, the "Three Emperors Sutra", which had completely disappeared, would reappear in the world.

Therefore, when Lu Yu found out that the jade slip in his hand turned out to be the book of immortals in the Han Dynasty, the "Three Emperors Sutra", the excitement in his heart can be imagined.

After raising his hand and inserting the arrow of the iron-tailed arrow into the brick crack of the blue brick on the cave wall, Lu Yu used his slightly trembling hands to hold the jade slip of the "Three Emperors Sutra" and approached the light source of the "Qiming Fu" at the end of the arrow, and slowly untied the gold thread tied to the jade slip, and gently opened the divine book.

"Isn't it......" When Lu Yu's eyes swept the first leaf of the jade slip, and saw the three big seal characters engraved on it, Lu Yu, who was so excited that even his lips began to tremble, muttered indistinctly: "Even the "Human Emperor Text" is there, could it be that this volume of "The Three Emperors" is the ...... of the whole book."

According to historical records, the three articles in the "Three Emperors Sutra", in the Tang Dynasty, there was only one article left in the "Emperor's Text", however, the jade slip in Lu Yu's hand turned out to be ......

"Wouldn't this be the so-called lonely book that Silk and passed to Zheng Yin......" Lu Yu, who was overexcited, began to think wildly, and as he continued to unfold the simple leaves, the three words "Dihuang Wen" came into his eyes......
