Realizing the possible effects of the dragon vein earth fire, Chu Feng's heart couldn't calm down for a long time. This time, not only did he find the essence of the dragon vein, but he also got a large amount of terrifying flames, which was an unexpected gain.

Half an hour later, Chu Feng finally calmed down, and began to extract the dragon vein essence from the accompanying bronze bell. In the face of the earth fire dragon vein essence, he did not dare to be careless, this kind of essence formed from the dragon vein earth fire must be as violent as a flame, with a great ability to react, and it is very likely to cause unimaginable damage to the physical body.

In the case of having great hope of breaking through to the Innate Secret Realm, Chu Feng would naturally be cautious, if he was careless and led to the consequences of being strict, it would inevitably have an impact on hunting for precious blood and true blood in the Spirit Realm in the future.

Fire dragons transformed by the essence formed from the dragon veins and earth fire shuttled over the sea of fire within the accompanying bronze bell, and they let out a low dragon groan, as if they were roaring and roaring.

Chu Feng's mind was connected to the associated bronze bell, and he began to urge the bronze bell to absorb the dragon vein essence qi. He was very careful and cautious, only ingesting a wisp of dragon vein essence, and he was not greedy.

"Huh!"

A wisp of dragon vein essence was incorporated into the dantian by Chu Feng, and the blazing feeling spread rapidly, from the dantian to every corner of his body, making him feel as if he was in a sea of fire, and the heat was unbearable.

Chu Feng endured the scorching pain of the fire, and hurriedly ran the "Supreme Overlord Body True Scripture" to refine the dragon vein essence, and the purple-golden blood qi poured into the dantian from all over his body, wrapping that wisp of dragon vein essence and forcibly refining it with the vigorous life essence qi, while dissipating the heat energy.

Although the dragon vein essence was wrapped in the life essence, it couldn't completely cut off the blazing heat, and Chu Feng still felt the pain like fire all over his body, but it was much better than before.

"Boom!"

A moment later, the dragon vein essence wrapped in the life blood qi suddenly exploded, and the violent energy suddenly shook the purple-gold blood qi, instantly sweeping through the entire dantian space, and at the same time, those heat energies were also rapidly subsiding.

The dragon vein essence was refined, and it exploded at the last moment, that kind of energy was terrifying, if it weren't for Chu Feng's special physique and strong body, the dantian would inevitably burst. Fortunately, his dantian was different from ordinary people, very tenacious, and withstood this energy, and those dragon vein essences were also transformed into heaven and earth essences in an instant.

Chu Feng's dantian was completely filled with pure heaven and earth essence, for these refined dragon vein essence, Chu Feng had a very strange feeling, it was very pure, but it was only about the same as the true blood in the heart of the ancient beast, but there was a special energy circulating in these dragon vein essence, which quickly surged from Chu Feng's dantian to all parts of his body, with a very strong penetrating power, which could be said to be pervasive.

At this moment, Chu Feng was not in a hurry to guide those dragon vein essence qi that were pouring all over his body, he was carefully observing and inducing, trying to find out why this dragon vein essence qi with the same purity as true blood essence could help him break through the bottleneck.

In the end, Chu Feng finally understood that the bottleneck of the Innate Secret Realm could not be broken through, not because the purity of cultivation resources was not enough, but because they did not possess the aura and characteristics similar to his True Dragon Divine Body.

However, the essence of the dragon vein is different, because it is the essence of the dragon vein bred by heaven and earth, and it contains a trace of dragon qi, which is more suitable for Chu Feng's physique, so they can penetrate all parts of Chu Feng's body, which is also more conducive to penetrating the barrier of the innate secret realm, so as to break through it.

After refining, the essence of the dragon veins surged to all parts of Chu Feng's body, and in this process, the "Supreme Hegemonic Body True Scripture" operated, and thousands of ancient character seals appeared in the flesh and blood, blending with the refined dragon vein essence, and the flesh and blood were constantly condensed under the dragon vein essence, and the dragon vein essence was gradually transformed into Chu Feng's life blood qi.

Chu Feng was a little surprised, he obviously felt that his physical body had become a little stronger, his life blood and qi were much stronger, and the powerful effect brought by the dragon vein essence shocked him. It's just a wisp of dragon vein essence that is refined, if you refine a transformed dragon vein essence, what kind of improvement and change will it make your physical body?

Prior to this, Chu Feng only knew that the dragon vein essence could help him break through the bottleneck he was currently facing and enter the innate secret realm, but he didn't expect that the dragon vein essence could make such a big improvement in the physical body, which was even stronger than the true blood effect in the heart of the water fly that he had used.

Chu Feng's mood was excited and excited, and he couldn't calm down for a long time. With these dragon vein essences, it is tantamount to being able to improve the realm more quickly and make his physical body stronger.

On this night, the valley was quiet, the sky was full of stars, and the moon poured down like water, covering the earth with hazy silver sand.

The bear child and Xiao Li'er lay on the fur of the lightning beast, and they made a bonfire, so comfortable. In the cave not far away, Chu Feng's treasure body flowed with a faint firelight, which was the light of earth fire transmitted from the inside of his body when refining the essence of the dragon vein.

Chu Feng's whole body was soaked with sweat, his thick black hair was messily attached to his back and face, he was suffering from the pain caused by the fire energy in the dragon vein essence, but the benefits he got were also huge.

After repeated ingestion and refining, Chu Feng had already refined an entire dragon vein essence, and his physical body had been greatly improved, his flesh and blood were brilliant, and his essence and blood were extremely vigorous. Within his several main meridians, there was a collection of majestic life qi and blood refined from the essence of the dragon vein.

Chu Feng condensed these life essences in the main vein space to prepare for breaking through the barrier of the Innate Secret Realm.

Time passed slowly, and the life essence in the main vein became more and more majestic, and it simply converged into rivers of essence, and when it surged gently, it made a rumbling sound, like a river rushing!

Such a momentum naturally alarmed the bear child who accompanied Xiao Li'er to look at the stars, and he knew that Chu Feng was preparing to attack the bottleneck of the Innate Secret Realm.

It had been several hours since Chu Feng entered the cave to cultivate, and he had been calm before, but now there was a sudden sound of surging blood, and he didn't need to think about it to know that he was about to reach the most critical moment now.

"I hope that Chu Kid won't make too much noise, otherwise it will be troublesome to attract some ancient beasts before breaking through......," the bear child muttered to himself, and then lay down on his back, his eyes looking at the twinkling stars in the night sky. With Xiao Li'er by his side, this guy seemed very relaxed, he knew that Xiao Li'er's sense of consciousness was very keen, and if an ancient beast approached, it would be discovered far away.

In the cave, Chu Feng's situation was indeed as the bear child guessed, and it had reached the last moment. After several hours of refining and accumulation, the majestic life essence has been gathered in several main meridians, completely filling the space in the meridians.

However, Chu Feng did not immediately mobilize those life essences to impact the barrier of the Innate Secret Realm, but instead continued to ingest and refine the dragon vein essence. In Chu Feng's opinion, if he has the essence of the dragon vein, he must break through in one fell swoop, so as not to waste time on Lang, but if he fails to rush through the level, his own meridians will also be damaged.

Therefore, Chu Feng had to make the most adequate preparations, the life blood qi in the main meridian had accumulated to a saturated state, but the dantian was still empty, he was now going to fill the dantian with life essence, and then cooperate with the life essence in the main meridian to impact the barrier.

If the life essence in the main meridian is weak when it hits the barrier, then it can be assisted by the life essence in the dantian, so that it can become the last energy to break through the barrier.

Time passed slowly, the bonfire outside the cave burned quietly, and the eyes of the bear child and Xiao Li'er also shifted from the stars in the night sky to the cave, they were all paying attention to Chu Feng's situation, waiting for him to break through the bottleneck and enter the innate secret realm.

"Boom!"

Suddenly there was a loud sound in the cave, like thunder, and the entire mountain wall shook violently, which made the bear child's heart jump violently, followed by a rumbling rush, like a thousand rivers rushing, and like a flash flood.

"The kid has finally started to rush through the level!" the bear child muttered to himself, he was a little dazed, and was shocked by the momentum that erupted when Chu Feng rushed through the level.

The dazzling purple and gold light shines out from the dark cave, illuminating the vast area of the canyon in purple gold. Under the illumination of the light, the surrounding mountains and rocks seemed to have turned into the purple gold divine mine of the circulating divinity, making this place gorgeous.

In the cave, Chu Feng sat in it like an enlightened god king, and endless ancient characters appeared on his body, imprinted on the body of Baohui, and his body exuded an indescribable aura.

In Chu Feng's body, the Supreme Hegemonic Body True Scripture was almost running to the extreme, the dense ancient characters were up and down, imprinted in every inch of flesh and blood, and the majestic life essence in the meridians rushed like a divine river to the barrier of the Innate Secret Realm, making a crazy impact.

"Boom!", "Boom!", "Boom!......

The loud noise shook the sky, coming from Chu Feng's body, this kind of sound was too terrifying, causing this canyon to shake violently, and the surrounding mountains and rocks rolled down, and the smoke and dust rushed to the sky.

The vigorous life essence, like a long river flowing, frantically impacted the barrier of the innate secret realm, each impact was like an eruption of a mountain torrent hitting the embankment, and the blazing purple gold light was transmitted out, illuminating the valley, and even reflecting this piece of heavenly dome into purple gold.

The bear child was already dumbfounded, and his mouth was called perverted. He came from a star field full of cultivation sects, and he had seen a lot of ancient blood physiques, but all those with strong bloodlines would be different from ordinary people when they broke through, and even had anomalies. But like Chu Feng, breaking through the innate secret realm can have such a momentum, the bear child is still the only one in his life, he has never even thought about this situation, it is really amazing.

"Nima, is this still a human being? But if you return to the outside world in the future, won't you overturn the heavens and the earth when you break through the big secret realm behind?"

The bear child was completely speechless at the movement made by Chu Feng, although he knew that the true dragon body was powerful, but Chu Feng's breakthrough was still far beyond his expectations, and he had to be shocked.
