Since the rock wall in the rock crevice could not be climbed with strength, Fang Zhuo could only slide down vertically from directly above the rock crevice. After he landed at the rock crevice, he reached into the hole that Fu Li had knocked out with both hands, and grabbed the cave wall hard. It's a bit risky, but there's no other way.

Enter the rock crevice, which is a deep cavern inside. Fang Zhuo's eyesight was now amazing, and he was not much affected in the dark. He walked slowly with the silver bat, until he went three or four miles deep, and several forks in the road appeared in front of him.

Fang Zhuo found that the cave slowly extended underground, and the cave was rugged and full of stalactites, which was actually an underground cave. Fang Zhuo randomly chose a fork in the road and walked in, and after walking for another half an hour or so, he gradually heard the murmuring of water in his ears. It is an underground river.

When you come to the Earth River, the cave becomes wider. The silver bat screamed happily and flew out of the city. Fang Zhuo saw it flying back and forth in the cave, although its ability to fly was not so superb, but its flying speed was not slow. There were some bright green points of light flying at high speed in the air of the cave, and every time the silver bat flew by at great speed, Fang Zhuo saw a point of light disappear. It turned out that it was predatoring. I think it usually comes in to hunt for food, just catch these small insects that glow.

In order to get rid of the shadow as soon as possible, Fang Zhuo quickly summoned the silver bat, which was not yet full, and groped its way towards the depths of the cave.

This underground cave system is extremely complex and extremely large. Fang Zhuo felt more and more shocked, this natural creation of the Heart Dao was really amazing, who would have thought that there was such an underground world in the depths of the earth?

For several days in a row, he kept choosing a fork in the road, constantly walking into the depths, and slowly the sense of crisis in his heart began to disappear.

As soon as this sense of crisis was eliminated, Fang Zhuo suddenly felt tired and hungry. The silver bat is okay, it can fly around him every day and catch some small bugs for food. But there wasn't much food on Fang Zhuo's body. He saved as much limited food as possible to eat, if it weren't for the spirit wine, I'm afraid he would have fallen down long ago.

In fact, in Fang Zhuo's jade box, there are still a lot of good things.

During this time, his knowledge of all kinds of wild fruits and spirit grasses was constantly improving. Not for anything else, he saw the grass and trees chapter some time ago. After reading the records and introductions in the book, Fang Zhuo realized that this cliff was simply a treasure trove! It was overgrown with many rare spirit grasses recorded in the book. He carefully interpreted, memorized, and then picked all the good things he saw on the cliffs. During this period of exploration, although there are not many excellent spirit grasses he has picked, they have gained a lot.

This cave seems to be extremely deep and wide, and I don't know how many days it will take to get out of it. In this cave, I don't know if there is any unknown danger in the road. After all, Fu Li's monster came out of this. Therefore, in the cave, Fang Zhuo didn't dare to eat the strange fruits and elixirs in the jade box at will. You must know that the last time he ate a supreme spirit fruit, he slept for more than a month! If he ate and slept for many days, he wouldn't know what monster's stomach he had entered.

What allowed Fang Zhuo to persevere, in addition to the powerful effect of the spirit wine, was also the Spirit Devouring Technique that he had been practicing hard every day for all this time!

Speaking of which, this Spirit Devouring Technique had actually been cultivated since a few months ago, but it had been intermittent and did not attract his attention. Ever since he had a splitting headache from trying to read the general outline of the talisman in the altar, Fang Zhuo had become very wary of this jade scroll in the sea of knowledge. However, some time ago, he couldn't help but open the book.

This time, he had learned the lesson of the last time, and he had only glanced at those basic runes, not looking at them closely. Dozens of pages have been flipped in this way, and new content has appeared.

"To cultivate runes, you must first cultivate the Spirit Swallowing Technique. ”

Fang Zhuo stopped and took a cursory look, and he was interested. It turned out that Xuanyuan Hao and Xuanyuan Hao brothers had once discovered an entrance to a mysterious realm in the depths of the vast ocean that crossed more than a dozen endless seas in the south of the Great Wilderness. After entering the Mystery Realm, there was a continent inside, and they called this continent the Cave Realm.

The so-called mystery world is described in detail in the Great Wilderness Chronicle. In ancient times, people often found some spaces connected to this continent, and they called these spaces mysteries. These mysteries are big and small, and they are very mysterious. According to the records of the Great Wilderness, the big one is even far superior to this continent, and the small one is only "one hundred and twenty steps".

However, judging from the records of the Great Wilderness, there are often great dangers and great opportunities in these mysterious worlds. The book records many cases of powerful people who mysteriously disappeared or died after entering a certain mysterious world, but it also records many legends of ordinary people who discovered the mysterious world and got a great opportunity in it and became a strong man in one step.

The mystery world discovered by the Xuanyuan brothers is very large, and the reason why they call it the cave world is because there is a strange human in this mystery world. This kind of person digs a burrow for his home, does not eat, drink, or move, and does not move for years. According to the book, it seems that this kind of person is even more lazy to move than a turtle.

Can they survive without eating or drinking? In fact, the Xuanyuan brothers discovered that the life expectancy of this kind of caveman is extremely high, "3,000 years long"! Ordinary cavemen can live for 3,000 years! Some of them are said to be able to swallow the aura of the nine heavens and absorb the essence of the universe, so that they can live forever between heaven and earth!

The Xuanyuan brothers stayed in the cave world for a long time, and finally tried their best to get this "Spirit Devouring Formula"! The brothers did a detailed study of this secret technique that cavemen relied on as a treasure, and finally found that this method was extremely powerful!

According to the records in the book, if it weren't for the fact that the brothers had already cultivated at that time, I am afraid that they would not hesitate to abandon the Xuanyuan family's family exercises and directly change to the Spirit Swallowing Technique!

The introduction in such detail in the general outline of the rune is to tell the descendants of the Xuanyuan clan that if they want to be strong and want to control the power of the rune, they must cultivate this spirit swallowing technique. If you can cultivate this strong method well, according to what is said in the book, that is, "the Three Realms can be arbitrarily vertical and horizontal"!

And reading the content of the Spirit Devouring Recipe also made Fang Zhuo smack.

"The one who is angry, the heaven and the earth are clear. Nourish all things and accept the universe, conceive all beings and nurture the ............ of heaven. The vastness of heaven and earth, the complexity of all things, are derived from an innate aura. Therefore, qi is the foundation of all things. Absorb qi from the body, filter it with divine sense, nourish it with soul, refine it with mind, and finally only have a trace of innate aura. The slightest wisp of it adds up to a lot, and it can finally reach the innate body!"

Fang Zhuo was stunned when he read it. The meaning of the book is very clear: this innate is not congenital! People often say congenital, but in fact it means that some people are born with a certain talent. Some people are born with unforgettable eyes, and some people are born with infinite strength, these abilities are born and are called innate by the world. And the innate that this Spirit Swallowing Recipe refers to is the innate before the evolution of heaven and earth, before all things are born!

Is this possible?

The thought of the Xuanyuan Clan's ancestor having a crazy feeling when he saw the Spirit Devouring Technique, so after discovering this Method, Fang Zhuo was also a little excited at first. Although he doesn't fully believe in the theory of immortals, it doesn't affect his moderate YY. However, after cultivating for more than ten days, this guy was a little disappointed.

He practiced the steps of the Soul Swallowing Recipe day by day, but he didn't even have that "slight" feeling! The only thing he gained was that he discovered that the so-called Soul Swallowing Recipe was actually not just a mouth. After cultivating according to the Soul Devouring Technique for a few days, he found that the Heaven and Earth Spiritual Qi could penetrate through every inch of his body!

Is this thing reliable?

Since then, he's been practicing without a match.

However, since seeing Fu Li attack with a thunderball, bombarding such a terrifying crater on the cliff wall, and such a terrifying thunderball silver bat could actually be blocked by the sound wave, Fang Zhuo moved his mind again.

It seems that the theory of magic still exists.

Since the little silver bats are so powerful, why can't I?

Stimulated by this, Fang Zhuo began to cultivate the Spirit Devouring Technique with all his might!

Since the book says that it takes time to make contributions, it is better to do it over time.

After practicing hard every day, Fang Zhuo finally felt the feeling of spiritual power in his body! Although it was very weak, Fang Zhuo could clearly feel that it was like a gas slowly gathering in his dantian, and it was flowing slowly and softly.

This feeling was completely different from the internal skills he had cultivated on the cliff some time ago! So Fang Zhuo could conclude that this was the aura that the Spirit Devouring Technique had brought to him.

Now that he has gained, Fang Zhuo's confidence has increased greatly, and every time he rests, he first has to meditate and practice qi, and slowly develop a habit.

Although Fang Zhuo didn't have the slightest impression of the innate or acquired nature of this aura, he could feel the benefits of this aura to his body. No matter how tired you are, as long as you start to run the Spirit Swallowing Technique,

Soon all the fatigue will be swept away.

As he continued like this day by day, Fang Zhuo's cultivation slowly and gradually found his way, and the problem of hunger was finally solved.

After walking for many days and how many miles he had traveled, Fang Zhuo finally found an underground river. With his current vision and skills, it is still easy to catch a few swimming fish in the underground river and eat. It's just that the fly in the ointment is that there is nothing to make fire on him, and even if there is, there is nothing combustible in this damp and dark cave. Therefore, although the fish caught is fat, it can only be eaten raw.

Although raw fish was difficult to swallow, the appearance of this river brought hope to Fang Zhuo.

This underground river is going to flow out of the mountainside after all, right?" Fang Zhuo thought. With this underground river, you should be able to get out of the ground sooner or later. However, he didn't expect that this departure would take several months!

Fang Zhuo's vision was not affected at all in the dark, plus his light skills were now extremely superb, and his physique was different from ordinary people, even in the rugged karst cave, the speed of walking was much faster than that of ordinary people walking on flat ground!

But even so, the swirling caves, the constant bifurcations, and the occasional dead end caused his progress to be very slow.
