When Mu Feng arrived at the sixtieth cave, he encountered a huge obstacle.
Because, starting from the sixtieth cave, the formations in each cave are super imperial formations.
This level of imperial formation is currently not something Mu Feng can break. Even with Ao Ling's help, it will basically be of no help.
Although Mu Feng was unwilling to give up, he could only give up.
Of course, if he passes the mark of law, he can temporarily gain extremely powerful power, and destroying the super imperial formation is not a problem for him.
But the price paid is too high.
Moreover, the holy spring in the Golden Book World is almost dry now, and Mu Feng does not dare to act so recklessly again. Otherwise, when he is exhausted, he will have to rely on himself to recover, which will be too slow.
"Master, this villain is really incompetent. He can't help his master. Please punish him!"
When Ao Ling saw Mu Feng's disappointed look, he immediately bowed and said with self-blame.
"This has nothing to do with you! The higher you go up the cave, the more powerful the formations are. The super imperial formation is beyond what we can solve! If I had known this, I should have asked Senior Ji to come over and help me break it first.
After these formations, enter the space under the Three Holy Temples!"
Mu Feng immediately thought of Ji Chen and muttered to himself rather annoyed.
Ji Chen is a Holy Lord-level powerhouse. Although he only has four limbs left, the strength he can exert is comparable to that of an ordinary Holy Lord. It is natural that he can break through the formations on the surface of any cave in the Three Holy Mountains.
.
However, it is impossible for Mu Feng to disturb Ji Chen now. After all, Ji Chen is currently concentrating on breaking the seal that seals his own head and body. It is not a good time to disturb others now.
"Since there is no other way, then just practice!"
Mu Feng no longer bothered with the other caves on the Three Holy Mountains, but directly left with Ao Ling and returned to the fragmented continent in the center where the holy spring was located.
Now, Jiuyuan is sleeping, Ji Chen is concentrating on cracking the seal, and Mu Feng does not dare to leave alone with the wordless golden book.
He simply planned to use this time to practice hard.
He was very aware of the concealment of the wordless golden book. As long as he stood still, he would not be able to detect it even if it was close at hand.
And once it moves, it might be possible, and the risk of being discovered is not small.
"Continue taking Phoenix Nirvana Flower!"
Mu Feng's eyes fell on an elixir that looked like the wings of a phoenix not far from the Central Continent, and its surface was burning with flames of gold and red that seemed to never go out.
At this moment, nearly one percent of the left petals of the Phoenix Nirvana Flower had been digested and absorbed by Mu Feng during this period.
Now, after Mu Feng reaches the fifth level of Martial Emperor, he has progressed from absorbing one thousandth of the Phoenix Nirvana Flower at once to directly absorbing two thousandths of the Phoenix Nirvana Flower's medicinal power.
This time, Mu Feng was going to try to absorb three thousandths of the Phoenix Nirvana Flower. He hoped that within this period of time, he could directly attack the sixth-level Martial Emperor.
Thinking of this, Mu Feng took a deep breath, glanced at Ao Ling not far away, and said: "Ao Ling, you are protecting me next to me. If anything happens to me, you will stop me immediately, do you know?"
Ao Ling nodded in agreement, and his eyes became much more serious. At the same time, he looked at the Phoenix Nirvana Flower with a look that was frightened, frightened, and also a little fiery.
After all, the Phoenix Nirvana Flower is a holy medicine. For Ao Ling, it only exists in legends.
During this period of time, he watched Mu Feng's cultivation improve by leaps and bounds, and this Phoenix Nirvana Flower was a major contributor.
Ao Ling also understood that with Mu Feng's talent and the assistance of the holy medicine, he might be able to catch up with him or even surpass him in cultivation within a few years.
Thinking of this, Ao Ling became more and more in awe of Mu Feng.
After giving instructions to Ao Ling, Mu Feng was highly concentrated and used the index finger and thumb of his right hand to grab three-thousandths of the petals of the Phoenix Nirvana Flower.
The moment Mu Feng touched the Phoenix Nirvana Flower, he could clearly feel the resentment and resentment in the latter's mind.
Almost all of the holy medicines give birth to spiritual wisdom and have the instinct to survive, so the holy medicines will transform and escape.
If the Phoenix Nirvana Flower had not been trapped by Jiuyuan early by using the power of law, Mu Feng might have been knocked away just now, and then the Phoenix Nirvana Flower would have escaped.
Mu Feng ignored the deep resentment transmitted from the petals of the Phoenix Nirvana Flower, and instead slowly divided the petals into three parts and swallowed them one by one.
Boom! But after swallowing all three petals, Mu Feng's eyes widened, and a thunderous sound erupted from his body.
I saw the surging power of the medicine, quickly digested along Mu Feng's stomach, and circulated towards his limbs and bones. The rich energy made all the hair and hair on Mu Feng's body stand up.
If you look carefully, Mu Feng's hair and hair actually emit streams of bright brilliance, as if they were forged from glass, and they look very crystal clear.
Even Mu Feng's skin seemed to have turned into glass, flowing with a mysterious radiance, like a god alive in the world.
But Ao Ling noticed that Mu Feng's expression was ferocious, as if he was enduring some kind of severe pain.
"Master! Are you okay?"
Ao Ling hurriedly stepped forward to check, but was stopped by Mu Feng.
"I'm fine, just keep watching and I'll tell you if anything happens!"
After Mu Feng finished speaking, he closed his eyes and began to run the Eternal Bible crazily in his body, operating it to the extreme, transporting all the surging medicinal power in his stomach to his entire body and limbs through his blood.
Of course, Mu Feng's body was also expanding at a speed visible to the naked eye. After all, although he was trying his best to convert the medicinal power, a considerable part of the medicinal power was still accumulated in his body and could not be released.
Time gradually passed, and after half a month, the swelling trend of Mu Feng's body had gradually eased.
And his body has expanded to about five times its original size.
In the next half month, Mu Feng's body no longer swelled, but gradually shriveled up, changing towards its normal form.
It was not until a month later that Mu Feng's figure returned to normal, and his aura increased a lot. He actually reached the peak of the fifth-level Martial Emperor, and was infinitely close to the sixth-level Martial Emperor.
Mu Feng, on the other hand, did not stop and continued to grab three thousandths of the petals of the Phoenix Nirvana Flower, swallowed it directly, and began to attack the sixth-order Martial Emperor.
Two months later, on the Central Fragment Continent, a shocking breath was heard rising into the sky, and the terrifying pressure spread towards the surrounding areas.
On this day, Mu Feng opened his eyes, an astonishing brilliance erupted in his eyes, and his aura had undergone earth-shaking changes from two months ago.
On this day, he was successfully promoted and became the sixth-level Martial Emperor.
