In the center of the square of the Aurora Martial Arts School, Zhang Zhao sat cross-legged, his hands spread out, and placed on his left and right knees.

Today's sky is gray, as if it could rain at any moment.

Looking at the gloomy sky, Gu Qing nodded and said, "This weather is good, it should be easy to lead the sky to thunder." ”

"Well, it's the first time I've taken the initiative to attract thunder, and I don't know what level of thunder I can attract, so I'm going to trouble Teacher Gu to look at it, don't let people cross the thunder pool by half a step, and at the same time, I hope that Teacher you can help me when I can't bear it and can't cancel. ”

"Hmm!"

Gu Qing nodded and said loudly: "Everyone is in a circle, retreat ten meters, and no one can cross the line." ”

When everyone retreated, Zhang Zhao slowly closed his eyes.

"The mind has no distractions, and the mind is empty. Turn emptiness into thunder, introduce itself, and everything in the world retreats. ”

As Zhang Zhao gradually emptied himself, the sky began to change.

Large dark clouds gathered and hung over the entire square.

"Boom!"

A muffled thunder rang out, and raindrops began to fall from the gloomy sky.

The rain was ticking down, and there were gradually fewer people in the square, and no one wanted to walk in the rain except for some people with higher cultivation levels who were cultivating in the distance.

At this time, in the martial arts hall, Chen Yang and Zhao San were practicing against each other, because there were fewer swordsmanship cheats, and he couldn't have no combat effectiveness without a sword, so Liu Yulan instructed Zhao San to teach Chen Yang his Vajra Divine Fist first.

"Hey, it looks like it's raining outside. ”

At this time, Xue Xianxian looked outside, only to see the raindrops the size of beans falling one after another, and countless shallows soon formed on the ground, as the rain became heavier and heavier, the water flow on the ground became more and more rapid, and at a glance, it was almost like a river.

Liu Yulan also walked over, looking at the dark clouds in the sky, she couldn't help frowning, she noticed that the thunder and lightning and rain at this time were natural phenomena, not caused by Zhang Zhao, so he still didn't succeed?

At this moment, the dark clouds above the school suddenly dispersed, the rain stopped, and a beautiful rainbow hung in the sky.

"Boom!"

Another muffled thunder rang out, resounding throughout the sky, and the ears of the people who shook began to tingle.

"Teacher Liu, look!"

Looking in the direction of Xue Xianxian's finger, I saw that the sky above the direction of the square was still overpowered, the dark clouds were thick, and it was only less than two hundred meters away from the ground.

Seeing this, Liu Yulan hesitated for a moment and said, "Students, stop what you are doing first, let's go to the square to have a look, and give you insight." ”

With that, Liu Yulan led the remaining students of the key class to the square.

At the same time, inside the principal's office.

The principal and the military officer have been friends for many years, and it is rare to get together again today, and the two of them sat down and drank tea, chatting about the understanding of so many years of cultivation.

Suddenly, a muffled thunder rang out, so loud that it seemed to penetrate a person's soul, and then the whole earth trembled.

Seeing the teacup on the table trembling faintly, the headmaster tightly frowned.

He stood up and looked out the window, startled.

"Good fellow, is this someone going through our school?"

The officer also came over, and when he saw the scene outside the window, he saw that the sky was clear and cloudless, except for the dark clouds over the square, among which the thunder and lightning were tumbling incessantly, which looked very terrifying.

"Let's go, go over and have a look!"

The two came to the square together, at this time the square seemed to have been cut off from the outside world, with the gate as the dividing line, the sky was clear outside, and the dark clouds were overwhelming inside, and the rain was pouring down.

Ignoring the heavy rain, the two quickly walked in.

After getting closer, I found that it was Zhang Zhao who introduced the heavenly thunder here, and all of this was formed because of him.

"Second uncle, Uncle Zhang. ”

Gu Qing politely greeted the two.

The principal looked at Zhang Zhao, who was meditating and cross-legged in front of him, and asked, "Is he leading the thunder?"

"Well, yes, it should be coming down soon. ”

The officer on the side looked at the tumbling dark clouds, and said suspiciously: "Ordinary martial artists should be able to come down soon when they trigger the heavenly thunder, but how long has it been since there has been no movement?"

"Huh?"

At this time, the officer suddenly let out a suspicious sound, because he suddenly saw that the dark cloud above his head seemed to have a flame, a purple flame.

"No, no, this is not an ordinary Xuan Thunder, this is the Purple Flame Divine Thunder. ”

Hearing this, the principal and Gu Qing also looked up, only to see that the dark clouds in the sky began to change, from the beginning of the irregularity to a dark cloud vortex facing Zhang Zhao below.

In the midst of this dark cloud vortex, the blue thunder and lightning had begun to disappear, and in their place were thunder and lightning mixed with purple flames.

"Qing'er, quickly take the children out of here and retreat out of the square. ”

"Hmm!"

Gu Qing turned his head and shouted, "Everyone, leave the square with me!"

Zhang Zhao's situation surprised the principal, because he directly crossed the Xuan Thunder and attracted the more powerful Purple Flame Divine Thunder, so at this time, he had already resonated with the Heavenly Dao, and the thunder pool below was not only within a radius of ten meters, it was very likely that the entire square was a thunder pool.

Of course, it was not only the principal who was surprised by such a shocking scene, but also the teachers and students of the whole school were shocked.

At this moment, the teaching building next to the square was already full of students, and they did not dare to enter the square to watch it up close, so they could only watch this scene in the teaching building outside the square.

They all felt the horror of this force, but what was really terrifying was not the power it presented, but Zhang Zhao's potential.

In the Aurora Martial Arts School, there are many students from famous families, and when they saw the scene in front of them, they contacted their own families one after another, and let their family members also come to watch.

In the second class, Wu Xiaomin looked at the scene in front of her and fell into hard thought, her expression was very complicated, she hesitated for a long time, and finally ran to the podium, picked up the landline and dialed her father's phone.

"Hey, Dad, come to school. ”

"What's wrong? Is someone bullying you?"

"Oh no, I don't know how to tell you, you just have to hurry up anyway. ”

In the playground, the officer and the principal stepped back ten meters again, watching Zhang Zhao's every move in front of them.

At this moment, I saw a few black shadows flashing in a hurry, and soon, two men and a woman appeared here.

These three people are all middle-aged people about forty years old, the male Qi Yuxuan, calm and atmospheric, the female posture is elegant, sinking fish and geese, and their bodies all exude a terrifying aura.
