The patriarch of the guardian brought Gu Chen and the others to the library and said, "This is the hiding pavilion of my guardian clan, this library is divided into nine layers, each layer contains 10,000 volumes, and the ancient book is in this library pavilion, called the Jiutong Zangjing, which records everything in the valley, it is a yellow animal skin scroll, but this volume has been unread for an era, so the old man does not know where this volume is."

"Shhh...... Ninety thousand volumes, when will this be found?" An Yi said in surprise. Pen Fun Pavilion wWw. ｂiquge。 ｉｎfo

"Patriarch, aren't you afraid that we will steal the exercises of your guardian clan?

"Hahaha...... Gu Chen Xiaoyou, since I can let you enter this library pavilion, I am not afraid that you will be able to check my clan's exercises, my clan's exercises are sealed, if you don't have the method of opening the seal, you can't open it at all, even if you can forcibly open it, the exercise book will be broken in an instant" The guardian patriarch laughed.

"Let's go" Gu Chen looked at everyone and laughed, and took the lead in approaching the library, looking at the various books densely placed, Gu Chen only felt a headache, I really don't know what year and month it will be to be able to find the Nine Passages of the Hidden Scriptures.

Gu Gu picked up a book casually and put it back in its place, he hadn't even read the introduction of this book, it was not easy to find the nine Tibetan scriptures in these 90,000 volumes, Gu Chen didn't want to waste this time.

Gu Chen released his soul consciousness on a whim, wanting to use his soul sense to flip through the books here, but Gu Chen's soul consciousness lost contact with him the moment it was released, as if this library could devour soul consciousness.

"Patriarch, why can't you use your soul sense here?" Gu Chen asked puzzled.

"Hahaha, this place was created by the Venerable of our clan, and there is a seal set by the Venerable of our clan in this library pavilion, and no one under the Venerable can use the soul sense, not only that, but even the spiritual power cannot be used here, if you don't believe it, you can try" The patriarch laughed.

Gu Chen did not shy away from throwing a punch forward, but he found that as the patriarch said, even spiritual power could not be used in this place, no wonder the patriarch could allow everyone to enter the library pavilion before, even if the strength of some of the people was enough to break the seal, but it was obviously impossible to do it in this library pavilion, unless the exercises could be taken away from this place, but who knows if they had the ability to walk out of this place with the exercises, this was built by the supreme.

"Let's be honest," Lei Shi said

"It seems that this is the only way" Gu Chen shrugged his shoulders helplessly, and continued to flip through the books, not letting go of any of them, and everyone began to hurriedly flip through many books, spiritual power, soul sense could not be used, everyone's speed was extremely slow, and it took a full day to turn over these 10,000 volumes of books, but unfortunately there was no Jiutong Tibetan Sutra on this first layer.

Everyone was like this, for one day, two days, three days, they kept looking through many books in this library pavilion, and until the eighth day, they still did not see the Nine Passages of the Canon.

"It seems that this Nine Passages Hidden Scripture is on the ninth layer, so I knew that I would have started looking for it from the top, so as not to waste so much time" An Yi complained on the side, and everyone nodded in agreement and walked towards the last layer.

A day later, everyone flipped through all the books, but unfortunately there was no shadow of the Nine Passages Sutra, Gu Chen looked at the patriarch and said, "Are you sure that the Nine-Passage Sutra is in this Library?"

"This Nine Passages of the Canon is here, have you leaked it?" asked the patriarch.

"Looking for" Gu Chen said with a dark face, starting to flip through the ninth layer, a few days later, everyone turned over this place again, but unfortunately they didn't see the shadow of the Nine Passages of the Tibetan Sutra, at this moment everyone was already physically and mentally exhausted, this time they couldn't use spiritual power, everyone didn't sleep for more than ten days, even if the monk wanted to be strong to ordinary people, it couldn't hold such a toss.

Gu Chen didn't want to give up, he believed that the guardian patriarch would not lie to himself, the Nine Passages Scripture must be in this library pavilion, Gu Chen once again flipped through it from the beginning, although everyone was tired, but they also joined the team, and read it over and over again, after several times, everyone had lost confidence.

Gu Chen began to look restless, "Isn't it possible that I am destined not to be able to embark on the path of the strongest Xuan Body?" Gu Chen muttered to himself.

"Don't worry, even if you can't find this Nine Passages of the Hidden Scriptures, isn't there still Xinyi? As long as she has mastered the Heavenly Separation Fire Technique, she can get the burial soil for you, at most she will have to wait for some time," Lei Shi comforted.

"I don't have time to wait" Gu Chen said angrily, less than two thousand years before the seal of the Heavenly Ruins Cave was lifted, Gu Chen didn't want to see the people around him die in front of him one by one, only by raising his cultivation to the Supreme Supreme Realm before the seal of the Heavenly Ruins Cave was lifted would he have the power to protect everyone.

"Ah......" Gu Chen roared angrily, and slammed his fist into a bookshelf in front of him, originally just wanted to vent, but he didn't expect this bookshelf to shake and almost fall, Gu Chen looked at this bookshelf and found that this bookshelf seemed to be different from the rest of the bookshelves, and there was a gap between it and the wall.

Gu Chen looked towards the gap and found that there seemed to be a book in the gap, which was covered with dust.

"It's the Jiutong Tibetan Scripture" Gu Chen shouted excitedly, and everyone also came over to help Gu Chen slowly move the bookshelf, Gu Chen picked up the books on the ground, and gently brushed off the dust on the cover, and the four conspicuous black characters of the Jiutong Tibetan Scripture appeared in front of Gu Chen's eyes.

"Hahaha, I found it, I found it" Gu Chen roared excitedly.

"Hahaha, it turns out that this book has fallen here, no wonder I haven't seen anything after looking for it for so long," the Guardian Patriarch laughed.

"Please also ask the patriarch to unlock the seal" Gu Chen smiled and handed the Nine Passages Sutra to the patriarch of the Guardian Clan, and the Guardian Patriarch took the Nine-Passage Sutra and made a few seals, handed the book to Gu Chen and smiled, "Let's go, since we have found it, then I will quit later, in order to find this Nine-Passage Sutra, our clan was forbidden to come here, since I found it, then let's leave, so that everyone in my clan can practice the exercises" The patriarch of the guardian laughed.

After walking out of the library pavilion, Gu Chen couldn't wait to flip through the Nine Passages of the Tibetan Scriptures, the previous pages were just the introduction of the blood domain, Gu Chen had no intention of watching, so he turned backwards, and when he turned to the introduction of the guardian clan, Gu Chen carefully studied it.

The record of the Nine Passages of the Tibetan Sutra is indeed consistent with the real situation, even the Tianli Hellfire Technique is recorded, and then Gu Chen saw the explanation of the burial soil, indeed this burial soil is not only only under the prison of the Hellfire this day, there is also a place called the Dark Valley, there is a burial soil here, but this Stygian Valley is extremely dangerous, it seems that this Stygian Valley has a slight connection with the guardian family, and it is said that this Stygian Valley also has the shadow of the Green Hell Fire.

And there is a kind of beast in this valley of the underworld, called the beast of the underworld, this beast is not viviparous, but naturally born in the valley of the underworld, this beast guardian of the valley, prohibits any living creature from entering, and anyone who trespasses will be blocked and killed by this beast.

Although this underworld beast is not highly intelligent, it can perceive any creature that trespasses into the Stygian Valley, and the attack is extremely strong, and the number is extremely large, it should be that this underworld beast is not maintained by spiritual power, so it is more troublesome, and the underworld beast has a very strong earth attribute in its body, as long as it is attacked and injured by the underworld beast, it is very likely to be petrified instantly and die in the Stygian Valley.

"Patriarch, I want to know if you have ever been to this Underworld Valley?" Gu Chen asked.

"Hahaha, I'm not satisfied with you, I've never been there, but according to legend, this Stygian Valley has some great connections with my Guardian Clan, so if my Guardian Clan goes to the Stygian Valley, it should have some advantages, but this is just a legend, even the Supreme of my Clan has never been there, so if you want to go to this Stygian Valley this time, you have to be careful. The Guardian Patriarch laughed.

"Senior Yu, this time I have to trouble you and Elder Yuan to go with me, the two of you have the highest realm here, and the other is that you are a guardian clan, and you have the Green Hell Fire in your body, maybe it is the relationship between this Green Hell Fire, and the Guardian Clan will have some connections with the Dark Valley" Gu Chen laughed.

"What about us?" asked Lei Shi and the others.

"You just wait here, and when Xinyi returns from cultivation, you can wait here for three years, if I don't come back after three years, then go back to the Killing Gate," Gu Chen said.

Everyone still wanted to say something, but Yuan Hongwen laughed, "With me here, you don't have to worry, even if I am defeated, if I want to escape, no one below the Supreme Realm can stop me, and there are few people to worry about."

"Alright then, be careful, when are you going to go?" asked Thunder Lion.

"Don't worry, rest for a few days and get ready" Gu Chen smiled.

"Gu Chen, the old man has a reluctant feeling," the Guardian Patriarch looked at Gu Chen and said.

"What's the matter?" Gu Chen laughed, for this patriarch Gu Chen knew what he meant, so Gu Chen just did it on purpose, and instantly scavenged something useful for this operation in this guardian clan.

"Previously, the six elders of our clan had a conflict with you, except for the Great Elder, the rest of the people had the Green Hell Fire Flame in their bodies all taken away, and I ask you to return it, this fire is the hard work of the elders, if you can return the fire, I will let the Great Elder of my clan do as he pleases, in this way, there are three people from the Disillusionment Realm by your side, and I believe that the success rate of obtaining the burial soil will be much more."

"Okay, it's a word, let no one come, I'll return the Green Hell Fire Tinder" Gu Chen laughed, achieving his goal, of course Gu Chen didn't mind returning the Blue Hell Fire Tinder.

After the six elders of the guardian clan appeared, Gu Chen returned the fire of the Blue Hell Hell, and also signaled Yuan Hongwen to remove the prohibition in everyone's body, only in this way would the great elder be willing to follow, if it was suppressed by brute force, Gu Chen was worried that this person would die at a critical moment, and it would really outweigh the losses.

Sure enough, after Gu Chen returned the Qingying Hell Fire and removed the prohibition that Yuan Hongwen had left in everyone's body, everyone's eyes looked at Gu Chen and the others much kinder than before.

After the patriarch of the guardian clan explained his intention to go to the Stygian Valley with Gu Chen, this patriarch did not have too much resistance, Gu Chen knew that the matter had already been decided, and he could set off as long as he was prepared for a few days.

"Burial soil, I can't live without you," Gu Chen thought silently in his heart.
