When Mu Feng arrived at the 60th cave, he encountered a huge obstacle.

Because, starting from the 60th cave, the formations in each cave are super imperial formations.

This level of imperial formation is not something that Mu Feng can crack. Even with Ao Ling's help, it will basically be useless.

Although Mu Feng was unwilling to give up, he had to give up.

Of course, if he passes the law mark, he can temporarily gain extremely powerful power. It is no problem for him to destroy the super imperial formation.

But the price paid in this way is too great.

Besides, the holy spring in the Golden Book world is almost dry, so Mu Feng dare not do so randomly anymore, otherwise he would have to rely on himself to recover after he was exhausted, so the speed would be much slower.

"Master, the villain is really incompetent and cannot share his worries. Please punish him!"

Seeing Mu Feng's face was disappointed, Ao Ling bowed and said with a guilty face.

"This has nothing to do with you! The higher the cave, the stronger the formations arranged, and the super imperial formations have exceeded the scope we can solve! If I had known this, I would have asked Senior Ji to come and help me break these formations before entering the space of the Three Saints!"

Mu Feng immediately thought of Ji Chen and muttered to himself with some annoyance.

Ji Chen is a powerful lord-level lord. Although he only has four limbs, his strength can be compared with ordinary lords. It is naturally no problem to break the formation on the surface of any cave in these three sacred mountains.

However, Mu Feng could not disturb Ji Chen now. After all, Ji Chen is now focusing on cracking the seal that seals his head and body. It is not a good time to disturb others now.

"Since there is no other way, then practice!"

Mu Feng no longer struggled with other caves on the Three Saints Mountain, but took Ao Ling away and returned to the central fragment continent where the Holy Spring was located.

Now, Jiuyuan was sleeping, Ji Chen was concentrating on breaking the seal, and Mu Feng didn't dare to leave alone in controlling the wordless golden book.

He simply planned to use this period of time to practice hard.

He knew very well the hidden nature of the wordless golden book. As long as he did not move, even if he could not detect it, even if he was close to him, he would not be able to detect it.

Once it moves, it may be possible, and the risk of being discovered is quite large.

"Continue to take the Phoenix Nirvana Flower!"

Mu Feng's eyes fell on a elixir that looked like the wings of the phoenix not far from the central continent. The surface was still burning with golden and red flames that seemed to never-ending.

At this moment, nearly one percent of the petals on the left of the Phoenix Nirvana Flower have been digested and absorbed by Mu Feng during this period.

Now, after Mu Feng's cultivation level reached the fifth-level Martial Emperor, he has improved from absorbing one thousandth of the Phoenix Nirvana Flower at one time to directly absorbing two thousandth of the Phoenix Nirvana Flower.

This time, Mu Feng was preparing to try to absorb three thousandths of the Phoenix Nirvana Flower. He hoped that he could directly attack the sixth-level Martial Emperor during this period.

Thinking of this, Mu Feng took a deep breath, looked at Ao Ling not far away, and said, "Ao Ling, you are protecting the Dharma next to me. Once I have any problems, will you stop me immediately?"

Ao Ling nodded repeatedly, his eyes became much more serious. At the same time, he looked at the phoenix's Nirvana Flower, and was also shocked and frightened, and there was a hint of heat.

After all, the Phoenix Nirvana Flower is a holy medicine. For Ao Ling, it only exists in the legend.

During this period, he watched Mu Feng's cultivation progress by leaps and bounds, and this Phoenix Nirvana Flower made an indelible contribution.

Ao Ling also understood that with Mu Feng's talent and the assistance of the holy medicine, he would probably be able to catch up with him or even surpass him in less than a few years of cultivation.

Thinking of this, Ao Ling became more and more awe of Mu Feng.

After instructing Ao Ling, Mu Feng was highly focused and grabbed three thousandths of the index finger and thumb on his right hand on the petals of the Phoenix Nirvana Flower.

The moment Mu Feng contacted the Phoenix Nirvana Flower, he could clearly feel the resentment and resentment in the latter's thoughts.

Almost all of the holy medicines have given birth to spiritual intelligence and have already had the instinct to survive, so the holy medicines will transform into shape and escape.

If the Phoenix Nirvana Flower had not been trapped by Jiuyuan's early use of the power of the 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 conveyed from the petals of the Phoenix Nirvana Flower, but slowly divided the seized petals into three parts and swallowed them one by one.

Rumble! But after swallowing all three petals, Mu Feng's eyes widened, and a thunderous sound broke out in his body.

I saw the surging medicinal power quickly digesting along Mu Feng's stomach and circulating towards the limbs and bones. The rich energy made Mu Feng's hair and hair stand up all over his body.

If you look closely, Mu Feng's hair and hair actually emitted dazzling brilliances, like glass forged, and looked very crystal clear.

Even Mu Feng's skin seemed to have turned into glass, flowing with mysterious light, like a god in the world.

But Ao Ling noticed that Mu Feng's expression was hideous and terrifying, as if he was enduring some severe pain.

"Master! Are you okay?"

Ao Ling hurriedly stepped forward to check, but was stopped by Mu Feng.

"I'm fine, keep watching, I'll say something if I have something!"

After Mu Feng finished speaking, he closed his eyes and began to circulate the Eternal Bible wildly, moving it to the extreme, and quickly transporting all the surging medicine from his stomach to his limbs and bones 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 use the mental method to transform the medicinal power, a considerable amount of medicinal power was still accumulated in his body and could not be released.

Time gradually passed, and half a month later, Mu Feng's body's expansion trend 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 and changed toward a normal form.

Until a month later, Mu Feng's body returned to normal, and his aura increased by a large part, and he actually reached the peak of the fifth-level Martial Emperor, infinitely close to the sixth-level Martial Emperor.

Mu Feng did not stop and continued to grab three thousandths of the petals of the Phoenix Nirvana Flower, swallowed them directly, and began to attack the sixth-level Martial Emperor.

Two months later, on the Central Debris Continent, a shocking aura surged into the sky, and a terrifying pressure spread around.

On this day, Mu Feng opened his eyes, and an amazing divine light burst out from his eyes, and his breath had changed drastically from two months ago.
