The resources of the Tianlian Demon Palace are too advanced. Yuan Feng knew very well that without external force assistance, then with the strangeness of the Zhenwu Divine Art, it would definitely take a long time for him to improve his cultivation level, and even if he had a long accumulation, he might not be able to improve.

However, with these resources in the Treasure House of Heavenly Refining Demon Palace, it is not difficult to improve the cultivation level of the Annihilation Realm.

In less than half an hour, Yuan Feng drove his cultivation level at the fifth level of the Annihilation Realm to the sixth level of the Annihilation Realm. This speed of promotion can be described as horrifying for the strong men in the Demonic Luo Realm.

Of course, then again, if ordinary people in the Annihilation Realm use these resources, then it is definitely not a problem to improve one level of cultivation at this time, even if you improve more realms.

The spiritual plant treasures in Wuwang Realm are not comparable to those in the Moluo Realm and the Dharma Realm.

The cultivation level has been upgraded to the sixth level of the Annihilation Realm. Although Yuan Feng's strength has been greatly improved, there is obviously a gap between the fourth level of the Cave Heaven Realm.

Yuan Feng was not anxious at all about this. Anyway, the battle outside would take a while, and he had a lot of time to slowly struggle in the Tianlian Demon Palace. Moreover, according to the Shaoyang Protector, even if those guys finished fighting, it would be absolutely impossible for them to get in.

The Tianlian Demon Palace has extremely strong defense. If it is not allowed by its master, even if the strongest Creation Realm comes, he can only stand aside and never use brute force to enter it.

Since the Shaoyang Protector has such confidence, Yuan Feng is of course nothing scary, and he also knows in his heart that since the super strong man in the Demon Luo Realm is hidden with the Heavenly Demon Palace, it means that the other party has definitely studied the Heavenly Demon Palace more than once or twice. After so long, the other party has not been able to enter the Demon Palace, and of course it is impossible for the next time to come in so easily.

Continue to improve your cultivation, Yuan Feng chose several identical red spirit plants this time. These red spirit plants also contain extremely huge energy, and the effect will not be bad at first glance.

There are also many such red spirit plants in the treasure house of the Tianlian Demon Palace. During the time of speaking, several red spirit plants were swallowed by Yuan Feng one by one, and his strength began to rise step by step like a rocket.

When you reach the sixth level of the Annihilation Realm, it is almost a watershed in the Annihilation Realm. Speaking of which, the subsequent cultivation level is not a big obstacle. What Yuan Feng needs to do is to swallow a lot of special energy into his stomach and transform it into his own cultivation and strength.

"The realm of the seventh level of the Annihilation Realm should have a qualitative improvement. Once I break through to the seventh level of the Annihilation Realm, then my power can definitely reach the realm of the fourth level of the Cave Heaven Realm. At that time, there should be no problem in subdivating people in the fifth level of the Cave Heaven Realm with the Blood Curse Divine Power!"

Feeling that his cultivation had reached the limit of the sixth level of the Annihilation Realm, Yuan Feng couldn't help but feel a little expectant. Now, it is his limit to subdue the fourth level of the Cave Heaven Realm with the Blood Curse Magical Power. If he wants to refine and subdue the strong man in the fifth level of the Cave Heaven Realm, his strength is undoubtedly insufficient.

However, at this moment, there are a handful of powerful people in the Cave Heaven Realm in the Tianlian Demon Palace, and there are six powerful people in the fifth level of the Cave Heaven Realm waiting for his inclusion. Only when his strength reaches the realm of the fourth level of the Cave Heaven Realm can he be able to subdue the six powerful people in the fifth level of the Cave Heaven Realm.

"Come on, the realm of the fourth level of the Cave Heaven Realm, hurry up and break through to me!!!"

Thinking of this in my mind, Yuan Feng suddenly grabbed a few spiritual plants again and swallowed them all.

"Shit!!!"

After the bright red spiritual plant drank, it instantly turned into a red airflow. The red airflow ended with extremely strangeness. Wherever it passed, every thread of Yuan Feng's power was activated by it. This ability is definitely something that cannot be compared with the Dharma Realm and the Moluo Realm.

“Crunch!!!”

When the energy was activated, Yuan Feng made strange sounds all over his body. As these sounds sounded, his meridians, flesh and blood, and even the internal organs, began to change drastically. The trace of energy merged into his body, and as he watched, his body became more and more tough.

If it were a person at the sixth level of the ordinary Annihilation Realm, if these energy were eaten, ten thousand strong people of this level would be burst. But for Yuan Feng, even if all these energy was integrated into his body, it would be a piece of cake.

Obviously, these energy not only activates Yuan Feng's true martial arts magic, but also activates Yuan Feng's Nine-Turn Profound Art. After this practice, God knows how many times the Nine-Turn Profound Art can grow.

"It seems that the Nine Turns of Mysterious Art is closer to these spiritual plants in the Wuwang Realm. After I improve my cultivation level, I will choose some suitable spiritual plants and strengthen the Nine Turns of Mysterious Art. If possible, I can try the next few turns of mysterious art, and maybe I can improve it!"

The Nine-Turn Mysterious Art at this moment was reinforced by the improvement of cultivation, not the realm of mysteries. In fact, if you want to improve the realm of mysteries, the difficulty in it is probably not very great.

Of course, even if it is strengthened and tenacious due to the improvement of cultivation, the growth of the Nine Turns Mysterious Technique is already very terrible. If Yuan Feng faces the four people in the fifth level of the Cave Heaven Realm again, even if he is still a little bit taller than his physical body, he will definitely be able to withstand it for a while.

For the time being, Yuan Feng had to increase the use of heavenly and earth treasures. There was no way, the Nine Turns Mystery's absorption of these energy was like a snatch. If he wanted to improve his cultivation, he had to feed the Nine Turns Mystery, so that he could ensure that he would take two-pronged approach and not delay any one.

Whether it is the True Martial Arts or the Nine-Turn Mysterious Art, the energy demand is too great. Yuan Feng initially used the heavenly and earth treasures used by people from the Annihilation Realm, but in the end, he simply took the treasures used by the powerful people in the Cave Heaven Realm as filling his own energy and let the two magical skills absorb it.

"boom!!!"

Yuan Feng didn't remember how many treasures he had swallowed and how many special spiritual plants he had supplemented. After about two full hours, he swallowed another spiritual vegetation that only a powerful man in the Cave Heaven Realm could use. This time, the Zhenwu Divine Art and the Nine Turns Mysterious Art were greatly satisfied, and his realm finally got another one as he wished, reaching the seventh level of the Annihilation Realm.

"Buzz!!!"

After breaking through cultivation, this time, Yuan Feng's seven mysterious caves were slight shocked. Then, streams of power from the cave, like a volcano erupting, gushing out from the depths of the seven mysterious caves. This time, the power of the cave, which was gushing out this time was definitely much larger than the power of the cave, which was slowly radiantly released before.

"I have finally reached the power of the fourth level of the Cave Heaven Realm!!!"

Feeling the changes deep in the seven mysterious caves, Yuan Feng was overjoyed. He knew that once his cultivation level broke through to the seventh level of the Annihilation Realm, his seven mysterious caves would definitely undergo a qualitative change. Now it seems that the effect is really good.

"Boom boom boom!!!"

When a large amount of power from the cave heaven was scattered, Yuan Feng's Dantian space also began to change drastically at this moment. The already huge cave heaven began to spread rapidly at this moment, and the stability of the entire cave heaven world was greatly improved, and the space level was much higher.

“Crunch!!!”

After breaking through his cultivation level, the Nine-Turn Mystery Art finally underwent a qualitative change. Yuan Feng could feel that all his body, all the meridians, bones, flesh and skin, had become one of them now, and everything seemed to be transforming towards a special form of existence.

"What? My Nine-Turn Mysterious Art... has actually had a trend of advancement?"

When Yuan Feng felt the changes in his body, he was overjoyed and stopped meditating and jumped up from the ground.

"It's great. It turns out that as the cultivation level increases, the Nine Turns Mystery will gradually reach an extreme. After this extreme reaches a certain level, you will naturally advance."

There are nine turns in the Nine-Turning Profound Art. Now he has only practiced the first four turns, but he can ignore the attacks of the powerful people in the fourth level of the Cave Heaven Realm. Now that his cultivation level is advanced, even if it is an attack from the fifth level of the Cave Heaven Realm, he can definitely take it as if nothing is seen. It can be seen that the power of the Nine-Turning Profound Art is beyond doubt.

The fifth turn of the Nine Turns of the Profound Art is to merge the meridians, bones, flesh and skin on the body into a substance that is neither meridians nor bones, flesh and blood. Once this turn is successful, Yuan Feng can almost reach the level of innate spiritual weapons in the prehistoric world. At that time, even a strong man who is much higher than him, he will not cause any loss to his body.

"That's great. If my Nine-Turn Profound Art can go further, even if it is the power of the fourth level of the Cave Heaven Realm, I can completely withstand the full-strength attack of people from the sixth level of the Cave Heaven Realm. At that time, if I encounter someone below the sixth level of the Cave Heaven Realm, even if I stand there and let them fight, they will not be able to hurt me a hair."

The improvement of the Nine-Turn Mysterious Art is even more exciting than the improvement of cultivation. You must know that it is much more difficult to improve this magical art to one level than to improve cultivation.

"Try to improve my cultivation level at another level. Whether or not I succeed or not, I will start practicing the Nine-Turn Mysterious Art. I must reach this fifth-Turn Realm."

With his eyes narrowed slightly, Yuan Feng had decided at this moment that when the next practice was over, he would try to practice the fifth turn of the Nine-Turn Profound Art. Anyway, he still had most of the corpses of the Void Dragon Beast of the Cave Heaven Realm, and that half of the corpses of the demon beast of the Cave Heaven Realm should be enough to support him in practicing the Nine-Turn Profound Art.
