Boom! Suddenly, a golden lightning suddenly appeared in the spiritual barrier condensed around Mu Feng, drew across the barrier, as if torn the barrier into two halves, followed by a deafening explosion.

This sound is so loud that it is like the thunder blew up in heaven and earth, shocking all things.

The golden lightning flashed away, and soon, in the barrier, the second and third... more and more golden lightnings emerged, densely filled the barrier.

The roar sounds echoed one after another, deafening and extremely harsh.

When the golden lightning reached its peak, Mu Feng slowly opened his eyes, and a golden thunder flashed deep in his eyes.

In an instant, all the golden lightning in the barrier stopped, while the mental power surged out of Mu Feng's eyebrows became stronger and stronger, sweeping across the barrier.

Wherever they passed, the golden lightning collapsed and disappeared. Finally, when this spiritual power spread throughout the barrier, all the golden lightning that ravaged the barrier disappeared.

Mu Feng's mental power was also strong to the peak and underwent an unprecedented transformation.

Looking closely, the barrier around Mu Feng was completely substantial, like a thick barrier, indestructible.

The prototype of the spiritual barrier has completely transformed into a real spiritual barrier.

Mu Feng successfully broke through inadvertent enlightenment and was promoted to a true imperial teacher.

He was able to break through the imperial teacher so quickly, so he naturally adapted to the right time, place, and people.

At the right time, he happened to have an enlightenment at a critical moment; at the right time, he was the most abundant energy in the forging of the God Tower; at the harmonious man, he was the experience of Mu Feng in his previous life who had broken through the imperial master without taking any detours.

With the right time, place, and people, it is actually not surprising that Mu Feng can make a breakthrough to the imperial teacher naturally.

Tear! As Mu Feng's eyes opened and closed, a golden lightning flashed through the sky in an instant, and then returned to the depths of his eyes.

Looking closely, there were golden electric wires in the deepest part of Mu Feng's eyes, as if there was a real thunder power inside.

This is the art of divine thunder! Based on the spiritual power, it is mixed and transformed into divine thunder. It has the speed and power of thunder. It is an extremely terrifying spiritual secret technique.

The magic of divine thunder must be used with the essence of the imperial master's spiritual power, so Mu Feng was unable to use such powerful means before, but now he can.

Moreover, many of his spiritual tactics are based on the art of divine thunder and exert various incredible power.

"After advancing to the imperial master, I finally mastered the magic thunder technique! With this technique, although I am just a first-time emperor now, it is enough to fight against the imperial master at the peak of the elementary level! If I can continue to hone myself and reach the peak of the elementary level of the elementary level, then I can fight against the intermediate imperial master."

Mu Feng gently pinched his right hand, and dense golden electric wires suddenly burst out from all around him.

These electric wires are not real lightning, but evolved from mental power. They do not cause much harm to the body, but can easily tear apart the warrior's soul and spiritual master's sea of ​​consciousness, which is an extremely terrible means.

"It seems that I have practiced for thirty-six days, and there is still one day left to switch to challenge mode again! I want to see how much bronze door is my limit after breaking through the Emperor Master!"

Mu Feng's eyes had a sense of fighting, but he quickly calmed down, sat cross-legged on the ground, silently absorbing the surrounding energy to consolidate the state of breaking through.

A day later, the scenery around Mu Feng's room changed again, turning into the valley of the challenge mode.

At the entrance of the valley, there is a broken bronze door. Through the entrance of the valley, you can see that there are equally broken bronze doors inside.

These bronze doors were all broken by Mu Feng before.

Although the bronze door in the challenge mode will be restored every time you enter the Forge Tower, if you do not go out in the tower, but challenge for the second and third time in a row, the bronze door will naturally not be restored. Which bronze door you challenge will be, which bronze door will be.

Soon, Mu Feng arrived in front of the 38th bronze door.

The surface of this bronze door is filled with a faint blue light, but the aura emits is extremely vast and powerful.

More than a month ago, Mu Feng tried his best to break the bronze door.

"break!"

Mu Feng looked calm and walked slowly towards the bronze door. With a void in his right hand, a golden lightning flash came in an instant.

Boom! Golden lightning penetrated through the bronze door, the huge door exploded, and Mu Feng slowly passed through the broken door.

Now, this bronze door is a waving hand to Mu Feng.

"break!"

"break!"

"..." Mu Feng slowly moved forward. Every time a new bronze door appeared, he only needed to wave his hand to summon golden lightning to easily destroy the bronze door.

In this way, Mu Feng arrived at the fiftieth bronze door with great momentum.

The spiritual pressure of the fiftieth bronze door has obviously undergone a transformation, which is completely different from the previous bronze door.

Mu Feng's eyes were solemn, and he sacrificed his spiritual barrier and expanded instantly.

He sacrificed his spiritual barrier for the first time, and it was obvious that the fiftieth bronze door did put a lot of pressure on him.

The dense golden lightning surged out of the barrier, and shot out quickly like a heavy rain, successfully shattering the fiftieth bronze door, and the momentum behind it was still as strong as a bamboo shoot.

In the end, Mu Feng stopped at the 60th bronze door.

He used all his strength to smash the sixtieth bronze door. After arriving at the sixty-first bronze door, he could not bear the terrifying mental pressure and almost knelt down on his knees.

In the area where this bronze door is located, every ten bronze doors are one level, and the spiritual pressure will undergo corresponding transformation behind the ten bronze doors.

After Mu Feng broke through the fifty bronze doors, he had to do all his skills.

Behind the sixty bronze doors, he had reached his limit and could not continue to move forward.

"It seems that my limit is sixty bronze doors now!"

Mu Feng murmured to himself, put away the spiritual barrier around him, and the surrounding scenery was also changing rapidly, turning back to his original room.

After arriving from the 37th bronze gate to the 60th bronze gate, Mu Feng actually extended the practice time for another twenty-three days.

Mu Feng did not continue to stay, but chose to leave.

He has been promoted to the realm of the Imperial Master. Even if he continues to stay, he will not be able to continue to advance. Since that is the case, then leave this extra time for the next time he is about to advance and maximize the use of time.

Mu Feng walked out of the room, went to the first floor lobby, and headed towards the counter in front.

At this moment, the first floor lobby is still deserted and there are no people.

Jian Xia was sitting cross-legged in front of the counter, meditating and practicing mental power.

Mu Feng did not disturb Jian Xia, but stood silently not far from the counter, waiting for Jian Xia to complete her practice.
Chapter completed!
