The sky is gray and blue, and the sun is fiery red.

There is a quiet everywhere, and occasionally there is a cool breeze blowing, and it is very comfortable to blow on people, just like a mother's little hand, stroking the hair of the wanderer, so that Mu Zifeng also feels a burst of comfort, and there is a desire to close his eyes and fall asleep.

But at this moment, he didn't have time to feel that kind of comfort and comfort, because he was concentrating on breaking the formation, and the breaking process had reached the most critical moment.

Seventeen major formations, he has broken the fifteenth layer, and now he is working the sixteenth layer, and the sixteenth layer formation is also quite weird, Mu Zifeng estimates, I am afraid that it has reached the level of the Tianzi formation.

Mu Zifeng is like a miner, constantly pushing forward. The formation that wrapped the palace was like a huge piece of ore, and as he continued to advance, the formation also recessed into a big hole, like opening a gap, and Mu Zifeng was like an ant digging a hole, constantly drilling and digging forward.

"Is this the sixteenth formation?" Mu Zifeng smiled slightly, although his face was a little pale and his head was buzzing, the corners of his mouth still curved out of a good-looking arc, because even if he completely cracked the seventeen major formations of breaking through the two-fold formation, wasn't this exactly what he was looking forward to?

At this moment, fifty days have passed, that is to say, five hours have passed outside, and his spiritual power has also been consumed, only a little bit remains, but he is still struggling to persevere.

Almost all the spiritual power pills on his body were eaten by him, and some spiritual herbs that could improve spiritual power were also taken out of the storage bag by him, chewed them raw, and swallowed them in his stomach. Although the medicinal effect of these spirit herbs was limited, at this moment, he didn't have time to refine the pill at all, but raced against time to break the formation.

Because, there were only ten days left, if he couldn't break through the seventeenth formation within ten days, all the formations he had broken before would be restored, and his previous efforts would be in vain. This is what he does not want to see.

Success, not failure!

After closing his eyes and pranayama, he only rested for half an hour, and Mu Zifeng's spiritual power began to operate at a high level again, although the spiritual power was not much, and the speed of advancement was like that of a snail, but as long as he advanced, sooner or later, the sixteenth major array would also be broken by him.

That's his obsession.

At this moment, in front of his eyes, the outline of that hall became clearer and clearer. It was a red hall, just like a temple in the world, and it had a good smell, similar to the smell of sandalwood burning, which came out of the hall in a curling way, so that when he smelled it, he felt that his spiritual power seemed to be strengthened a little.

"I'm afraid there are magic treasures in this hall that improve mental power, right?" Mu Zifeng thought secretly.

And that hall is now his only goal and motivation.

As long as he cracks the last two formations, he can enter the main hall, where at least one thing belongs to him, which is also what Tallinn made clear to him before, he doesn't know what the magic treasure is, but there is still a magic treasure in the process of breaking through, which can be regarded as an unexpected gain.

"Break it for me!"

Mu Zifeng also used all the spiritual power that he had just born, and as soon as the spiritual power appeared, he rushed towards the fluorescence outside the big array, and the fluorescence suddenly dimmed, and something similar to a bead also appeared in his mind, the bead was the size of a football in the world, gray and white, hanging above the sixteenth major array, constantly rotating, and also repairing the damaged part of the big town.

"Is this where the eye of the formation is?" Mu Zifeng's heart was overjoyed, and his spiritual power flew out steeply, surrounding the gray-white beads the size of a football.

The bead was stunned, as if someone was manipulating, and it flew out, and there was a thin layer of synovial fluid on the bead, and the synovial fluid was very viscous, just like the liquid secreted from the surface of the loach in the world, making the bead slippery and very difficult to grasp.

"Come over to me!"

Mu Zifeng also came to be strong, seeing that one move didn't work, he used the second move, and the flying sword was sacrificed steeply, but he didn't choose to split the bead, but scraped off the slippery fluid on the surface of the bead, so that the gray bead revealed its original face, and there were some pitted hemp surfaces on it.

Mu Zifeng's spiritual power moved again, and the bead flew towards him suddenly, but halfway through the flight, the bead began to struggle again, as if it was extremely reluctant.

"Come over to me!" Mu Zifeng suddenly borrowed a part of the spiritual power of all the demon borers in his body, so that his spiritual power grew up suddenly, and the spiritual power that wrapped the bead was like a net, no matter how the bead struggled, it was still stuck in the center of the net, and he couldn't move anymore.

Mu Zifeng stretched out his hand, and the bead fell into his hand, and as the bead started, he felt as if a layer of light mist was broken in front of him, and the sixteenth major array was also successfully broken by him.

The bead whizzed out and disappeared into a mist of light.

The spiritual power radiated out, and the palace became clearer in his mind, and he felt that the space for his broken formation to advance was even narrower, so narrow that he couldn't even stretch his arms and legs, as if the mine hole dug by a mining miner suddenly collapsed.

The coercion around him is like a tide, he is like a frogman diving into the deep sea, his body is full of coercion, the slightest carelessness, the whole person will be crushed into a meatloaf, making him chest tightness and shortness of breath, breathless.

"Is this what Nataring means when he says that if he can't break the formation, he can't go back? It's really a bit of trouble!" Mu Zifeng also felt a thick egg pain, if he really couldn't break the last seventeenth major array, I am afraid that he was really in danger of falling here.

"No, it has to be broken!"

He also clenched his back molars, and secretly cheered himself in his heart, "So many storms have come over, what can a small formation do to me?"

A sky-high pride rose sharply in his heart, and he seemed to see his parents in front of him, his sister Mu Zixin, the mountains and rivers of the Python River Continent, and the blazing and earnest eyes of Rui Sisi, Lei Bao, Cen Long and others.

For them, no matter how difficult it is, they have to fight hard!

These were all his relatives and friends, how could he easily leave them behind? Therefore, this seventeenth major formation must be broken or not!

With such thoughts, he regained his spirits, and he didn't care about how many years the herbs in the storage bag were, and he desperately stuffed them into his mouth as if he didn't want money, until all the herbs related to spiritual power were stuffed into his mouth by him, and then he stopped.

The herb turned into a rolling power, and he felt that his mental strength had recovered very quickly, and his mind was clearer.

Although using the elixir spirit herb to improve the cultivation of spiritual power is likely to leave sequelae, but in this situation, he has no choice, if the person is gone, what is the use of keeping those herbs!

The array and array flags were also taken out of the storage bag by him and placed in front of him, the basin-sized array plate emitted bursts of ghostly light, and the eight array flags were also windless and automatic, making a fluttering sound, making the entire array and array flags look majestic and very windy, which also increased his confidence a lot.

Mu Zifeng chose four corners and planted the array of flags in the direction, and the array was firmly grasped by him.

Everything is ready, only the east wind is owed!

Closing his eyes and adjusting his breathing, he turned the turntable violently, and the eight array flags suddenly merged into the large array, and disappeared at once.

He knew that with the help of the formation flag to break the formation, it was necessary to integrate the array flag into the big array, and then open up a passage in the big array, or go straight to the Yellow Dragon, or find the location of the array eye, and then lock the array eye, use the array disk to control the array flag, and break the array eye, so that the big array finally became an ownerless big array, and then achieved the purpose of breaking it.

And the use of array flags to break the formation will achieve twice the result with half the effort, which is the preciousness of the array flag.

With the integration of the array flag, the big array also sent out a slight vibration, as if it was extremely reluctant, and it actually gave birth to a repulsive force, as if it wanted to exclude the array flag.

Mu Zifeng was also desperate, in addition to his own spiritual power, he also transferred the spiritual power of all the demon borers, so that with the assistance of the herb, his spiritual power returned to eighty percent of its peak, and those demon borers were lying weakly in the gossip plate, unwilling to move, their little eyes rolled over, and they hibernated.

After breaking the formation this time, these demon borers may have no spirit for a long time.

But Mu Zifeng's eyes were red, and he couldn't live that much.

Fortunately, these demon borers have not been used at this moment, so Mu Zifeng doesn't care if they hibernate or not.

With the suppression of his spiritual power, under the two-pronged approach, the big array no longer had time to take care of the eight array flags that he had integrated, and could only be tired of dealing with Mu Zifeng's spiritual power attack.

"Could it be that this is the Tianzi Double Formation?" Mu Zifeng's head was like a computer in the world, constantly calculating, and the ore-like hall wrapped in the formation was also revealed little by little.

Suddenly, a purple light flashed, and the seventeenth major array suddenly became fierce, dark clouds were thick, and the black tide was rolling. Moreover, there was a faint sound of thunder in the air, and the sky above the vermilion hall was also lightning and thunder, and more than one wave of rain and fog also continued to smash towards Mu Zifeng, making his hands and feet cold, and his body was also wet, as if he was falling into soup.

"What's going on?" His heart moved, "Could it be that the array of flags triggered a certain mechanism in the fusion?"

But in any case, he must break this big array, one is related to his third-level assessment results, and the most important thing is that if he doesn't break this big array, he doesn't know if he can get out of it!

"Regardless of your thirty-seven twenty-one, since you are here, let the master stay here!"

Mu Zifeng took out the Wind Thunder Bell from the storage bag, the Wind Thunder Clock, since the combination of male and female, has become more powerful, and the power of the high-grade magic treasure is also vividly exerted.

With a "whoosh", he threw the wind and thunder bell into the air, and the wind and thunder bell rose in the storm, and soon rose to the size of two oil tanks in the world. The diameter is at least ten meters away, the bell mouth is pitch black, and electric snakes are flying.

"Suck it for me!" Mu Zifeng manipulated the wind and thunder clock to suck it at the black clouds in the sky.

The black cloud seemed to have encountered a natural enemy, and it was suddenly swept away by more than two-thirds of the wind and thunder, and the rolling thunder and lightning in it were all sucked in by the wind and thunder bell.

"Buzz!"

After absorbing the black clouds and lightning, the color of the wind and thunder clock turned from gray to dark black, emitting black light like ink, black and bright.

Although the size of the Wind and Thunder Clock has not changed, one after another is far better than the previous coercion, and it is also emanating from the Wind and Thunder Clock, which makes people feel restless at a glance.

Suddenly, there was a "pop", and a black object fell from the sky.
