Chu Feng's mood was very heavy, and he came to this hall unintentionally, the cave was sealed, there was no way out in all directions, and there was a mysterious woman and a terrifying black water snake sleeping in the center of the hall.

In such a situation, don't say that people in the realm of Chu Feng, even those powerhouses who have cultivated to several great realms of the Dao Palace Great Secret Realm will probably be terrified.

"It seems that there is no other way now...... Chu Feng turned his head to look at the stunning woman and the black water snake sleeping on the crystal floor in the center of the main hall, although there was some hair in his heart, he gradually got used to it, and he didn't have too much fear.

After a long time, even the big fear in my heart will gradually calm down.

Chu Feng is a very calm person, and he knows that he is currently trapped here, no matter what kind of situation will happen, he can only face it bravely, there is no way to avoid it, and it is completely useless to worry.

"The Black Water Snake has been sealed from ancient times to the present, and its cultivation must be unimaginably strong. Even if such a being is asleep, most of them still retain a wisp of divine thought, and it must have known that I was here, but it didn't make a move. It can be seen that as long as it and the woman have not broken through the Life Stone Source Liquid, they will not attack me. Now, all I can hope for is that the three Divine Dao Immortal Soldiers will bombard the Nine Dragons Dao Peak, and when they collide with the Xinghe Dao Divine Map, they will affect this place, thus destroying the ancient formation here, and there may be hope of leaving at that time......"

Thinking of this, Chu Feng sighed deeply, and he was no longer obsessed with looking for an exit, because there was no exit at all. He sat down on the spot, took out the piece of life stone source ore he had just obtained, and stroked it gently, his eyes gradually brightened.

This Life Stone Source Mine was very large, and with such a volume, the Life Stone Source Liquid contained in it was at least tens of thousands of years, which was a rich cultivation resource for Chu Feng. If you hadn't come to the interior of the Nine Dragons Mountain Range, it would have been almost impossible to get so much Life Stone Source Liquid at once, unless you infiltrated the mining areas of those big forces to steal their temporary warehouses.

If you want to turn it into the source liquid of the life stone, you must refine and condense it with divine energy, and refine and condense all the essence inside the ore into nothingness, and then those life stone source liquid will be condensed into liquid, and then you can judge its quality according to the color of the source liquid.

"If I can leave this main hall, and then find a few such life stone source mines, and get high-quality source liquid, maybe there will be no need to go to the Northern Regions......" Chu Feng stroked the life stone source mine, he couldn't put it down, this is the resource that can make him stronger, and it is also the main resource that the monks under the secret realm of the Dao Palace need to improve their realm.

Of course, in addition to the Life Stone Source Liquid, there are also the treasures of the gods and the dragon marrow in this heaven and earth, but those things are too rare. For other cultivators, they may be lucky enough to break through the realm with a little bit, but for Chu Feng, it is far from enough.

His physique is too special, the resources required for each breakthrough realm increase several times, and compared to other cultivators, the amount of resources required in the same realm is also hundreds of times, or even more, it will scare people when they say it!

"Huh!"

Chu Feng's hands bloomed with a brilliant divine light, he put his palm on the life stone source mine, the divine sea in his body churned, and the divine energy essence poured into the source ore like a great river, and immediately there was a pure life breath overflowing, and with a little green divine radiance, the entire hall quickly turned the entire hall into a green space, full of vitality.

The life source liquid inside the source mine gradually condensed, and those stone slags continued to evaporate under the divine energy essence, but in just more than ten breaths, the inside of this stone source mine was filled with light green liquid, and the surface was only wrapped in a finger-thick crystal stone skin, and the green light of the life source liquid full of vitality bloomed through the crystal stone skin, light green and light green, very beautiful.

"Ordinary Life Stone Source Liquid...... Chu Feng muttered to himself softly, although it was not the high-quality source liquid he was expecting, but it was expensive in large quantities, and he was not disappointed. Even if it is of ordinary quality, it is enough for him to break through to the Divine Bridge Secret Realm!

With so many life stone source liquids, Chu Feng weighed them, there were about twenty-five thousand catties, and he was very excited at the moment, and when his mood calmed down a little, he took the source liquid into his body, and then began to think about what to do next.

"Now that I'm trapped here, there's nothing else to do anyway, instead of wasting time waiting, it's better to cultivate well and improve the realm. Since this hall has been imprinted with ancient formation patterns in ancient years, and it is also the important place for ancient demons to touch a tribe, thinking that these ancient formation patterns must be extraordinary, maybe it may be possible to cut off the heavenly machine, so that the order laws of the outside world cannot be sensed, which means that it will not attract the divine pattern catastrophe!"

Chu Feng thought about it carefully, and had this speculation in his heart, although he couldn't be sure if it was really as speculated, but he didn't hesitate, even if he put the inferior life stone source liquid that he had obtained from the Li family's treasure house in the Divine Sea, he began to refine the divine energy essence and blood qi.

"Boom!"

The seal of the golden phantom in the body was unsealed, and the divine energy essence instantly boiled to the extreme, like the Dao Dao Divine River was surging, making an earth-shattering sound, and the hall that shook the hall rumbled.

The seal suppression was lifted, and a vast heavenly power immediately descended, which immediately made Chu Feng feel a creepy feeling. This is a sign that a catastrophe is coming, and if it falls, it will definitely be terrifying.

This tribulation was different from the past, because Chu Feng's accumulation in the Divine Pattern Secret Realm was too deep, and the five geniuses of the Divine Pattern Secret Realm fell into the Great Tribulation, which was naturally very terrifying.

Just when Chu Feng felt that the heavenly power was shrouded and the catastrophe was about to come, many dao patterns flickered on the stone wall of the main hall, and at this moment, he felt as if he had come to a special space, and the vast heavenly power suddenly disappeared, and he could no longer sense it.

"It turns out that it can really cut off the induction of the Heavenly Dao order, and you don't need to cross the Divine Pattern Tribulation!" Chu Feng was already ready to cross the Tribulation, but he didn't expect that the Dao Pattern in the main hall flickered, cutting off the Heavenly Dao Induction.

The essence in the life stone source liquid continued to pour into the Divine Sea, being refined by the divine energy essence, Chu Feng's entire body was glowing, every inch of his skin was full of divinity, and the surface of his body was even in contact with a thick light cocoon, and the rumbling sound coming from his body never stopped.

When he was cultivating, under the transparent crystal ground, the black water snake soaked in the divine source liquid looked at him for a moment with diamond-shaped eyes. Although its body did not move, it made people feel that it had already woken up, and those eyes were very intimidating.

Chu Feng could sense a pair of indifferent eyes staring at him during his cultivation, this feeling made him feel cold all over his body, and he knew that it must be the black water snake.

However, since the Black Water Snake didn't make a move, Chu Feng gradually calmed down again, concentrating on refining the Life Stone Source Liquid and interweaving the Divine Pattern in the Divine Sea.

Time passed in a flash, and before he knew it, a whole month had passed, and Chu Feng's internal organs were all branded with divine patterns, and both his divine cultivation and physical body had been greatly improved.

The Life Stone Source Liquid collected from the Li Family's treasure house had already been consumed, and from the Fifth Heaven of the Divine Pattern Secret Realm to the Sixth Heaven, the Life Stone Source Liquid consumed by Chu Feng was terrifying.

Originally, Chu Feng thought that just the thousands of catties of inferior life stone source liquid collected by the Li family would be enough to improve to a realm, but in fact, it was far from enough. This breakthrough consumed a thousand catties of ordinary life stone source liquid.

The Life Stone Source Liquid found in the Li Family's treasure house was a defective product, and thousands of catties were only one or two hundred catties of ordinary Life Stone Source Liquid. If it weren't for getting 25,000 catties of ordinary source liquid, it would be impossible to break through to the Sixth Heaven!

"According to this calculation, the life stone source liquid to be consumed to cultivate to the Seventh Heaven of the Divine Pattern Secret Realm requires four thousand catties. Breaking through from the Seventh Heaven of the Divine Pattern Secret Realm to the Divine Bridge Secret Realm requires five times the resources, that is, 20,000 catties!"

Chu Feng made a rough calculation, this time he got the Life Stone Source Liquid that was just able to allow him to cultivate to the Divine Bridge Secret Realm, and if he wanted the nine realms in the Divine Bridge Secret Realm, the Life Stone Source Liquid needed for each realm had increased by four times, and when he said the last few realms, the source liquid needed for each realm was astronomical, I am afraid that those demigod inheritances, even the divine inheritance and the Eternal God Dynasty would be difficult to support such consumption!

This account was simply unbelievable, in the past, Chu Feng thought that the middle and late stages of the Divine Pattern Secret Realm only needed dozens of catties and a maximum of a hundred catties of source liquid to break through a realm. But I didn't expect that the fifth heaven to the sixth heaven would require a thousand catties!

In this way, it costs 20,000 catties to break through to the Shenqiao Secret Realm One Heavy Heaven, and so on, cultivating to the peak of the Nine Heavens of the Shenqiao Secret Realm requires 1.3 billion catties of ordinary life stone source liquid, what a terrifying number!

Chu Feng hadn't carefully calculated the amount behind before, because he hadn't used the Life Stone Source Liquid to cultivate. Now that he counted this number, his face turned green all of a sudden, and he almost felt that the road ahead was dark, and he couldn't see the light at all.

"It is said that the road of the Primal True Dragon Body is very difficult, it seems that it is not only the enemies encountered along the way, but also the resources needed for cultivation. I don't know how the true dragon bodies of the past generations did it!"

Chu Feng smiled bitterly in his heart, if he said this number, those Eternal Divine Dynasty and Divine Spirit Inheritance would all be scared to death. 1.3 billion catties of ordinary life stone source liquid, I don't know how many large ore veins need to be mined to get it, maybe the treasure troves of all the forces may not be able to gather so many ordinary qualities.

Now, all Chu Feng thought of was the high-quality Life Stone Source Liquid. The exquisite quality is equivalent to ten catties of ordinary quality, the flawless quality is equivalent to a hundred catties of ordinary quality, and the perfect quality is equivalent to the ordinary quality of a thousand catties.

In this way, even if all of them used the perfect Life Stone Source Liquid, it would take more than one million catties to cultivate the last realm of the Divine Bridge Secret Realm, not counting the consumption of those realms in the front, which made Chu Feng feel deeply powerless.

"It would be nice if you could get the Life Divine Source Liquid, one catty of Divine Source Liquid is equivalent to a hundred catties of perfect source liquid, and 100,000 catties of ordinary source liquid. With my consumption, in the end, only a god-level source liquid can solve the problem......"

Thinking of this, Chu Feng couldn't help but cast his gaze on the god-level source liquid sealed under the crystal ground, feeling the dreamlike life essence overflowing from it, and he couldn't wait to take it for himself immediately.

But there is a black water snake inside, not to mention, there is also a mysterious woman, any of them are definitely powerful, if you want to get the god-level source liquid inside, I am afraid that you will not be able to come with Shinto immortal soldiers.

After a long time, Chu Feng's heart gradually calmed down, he abandoned all the distracting thoughts in his heart, and no longer thought about the future, what he wanted to do now was to make good use of this time to refine the source liquid and improve his cultivation realm in this trapped process, no matter how much he thought about in the future, it would only be useless to increase his troubles.
