Let the system try to save the world

The first two stars of the Big Dipper, Tianshu and Tianxuan, are connected in a straight line, and if the straight line is extended five times, it becomes the fixed North Star.

The Big Dipper in the night sky has been rotating around the North Star since ancient times. Therefore, the Tiangang Big Dipper Formation, which was born from it, needs to rotate around the North Star no matter how it moves.

Xitong cannot see, so naturally he cannot quickly locate the position of the North Star.

Qin Xu and the others knew this very well, and they guarded the North Star position tightly. Xi Tong's slight thought of occupying the North Star position was extinguished, and he was eventually forced to the wall.

On the other hand, Xitong was also retreating towards the wall. If it weren't for the wall as a reference line, how could Shen Anzhi accurately locate the position of the North Star?

Talented people like Qin Xu and others probably wouldn't have thought that the hand gestures Xitong made were not some profound spells.

It was just a very short Morse code. When Xitong was making a telegraph in the classroom, he told Shen Anzhi some of the simplest codes.

After discovering that the other party had set up the Tiangang Big Dipper Formation, Xitong used gestures to remind Shen Anzhi to pay attention to the first and second stars, Tianshu and Tianxuan.

Shen Anzhi received his signal and moved over quietly. Qin Xu's attention was all on Xitong. He was so angry about the tricks of Shen Anzhi and Xitong that he had no energy to focus on Shen Anzhi, an ordinary human being.

After Shen Anzhi came closer, Xitong did not notice that the Tiangang Beidou was damaged. He thought that Shen Anzhi was standing in the wrong position, so he tapped the wall tiles with the heel of his shoe to ask her to adjust her position.

Until that moment, when the aura of Tiangang Beidou was blocked, Xitong knew that they had succeeded.

"The North Star is for you." Qin Xu said coldly. The seven people's uniform steps began to become a little messy. "What's the point of trying to be clever with humans?"

"Indeed." Xitong covered his face with his hands, and a faint black gas began to emanate from his body. Bloody stripes began to grow from under his neck.

His amber pupils gradually turned dark, and his whole aura gradually became evil and terrifying.

Despite this, Xitong still stood in front of Shen Anzhi.

Invite the god to possess me! The heart-eating demon has arrived!

Shen Anzhi, who was closest to him, glanced at Xitong's back with concern. He stepped firmly on the center of the formation. Even though this was within their plan, he still couldn't help but worry about Xitong.

Lu Jingming rubbed his hands. He was a little eager to make a move and stared at one of them shrewdly. However, due to the atmosphere between the two sides, he forced himself to squat where he was.

"I wonder what else you can do?" Qin Xu swung the whip and attacked Xitong's head. "No matter how strong your heart-shaping ability is, it can't affect me. You're wrong!"

"Xitong (system)!" Qinxu laughed, "It must be unpleasant to be affected by the negative emotions of Shaxin!"

"You emotionless monsters..." The water vapor in the air generated a large number of spikes in the few seconds after the whip was swung. By the time it reached Xitong's face, it had turned into a thick mace. "Die!"

Xitong raised his hand, and the mace seemed to be stopped by something invisible, a few centimeters away from him.

"Protective spiritual energy... How is that possible?" Qin Xu's expression was blank for a moment, "You are clearly only in the Qi Refining Stage."

How could I not be able to break your protective aura? !

"There are a lot of negative emotions in my mind right now." Xitong opened his eyes and pushed the mace against his temple with one finger. The ice crystals on it instantly sublimated into mist and disappeared into the air.

My water control technique! Qin Xu's pupils shrank. He didn't feel Xi Tong's action of tearing open the space, which meant...

Xitong completely relied on spiritual power to destroy his water control technique.

Qin Xu couldn't believe it and couldn't help but take a step back. Someone behind him put his hand on the back of Qin Xu to stop him from retreating.

Tiangang Beidou could attack or defend. The others stood together, protecting Qinxu in the middle. One of them said in a deep voice, "Since we've done it, let's do it."

A stream of pure spiritual energy poured into his body. Qin Xu bit the tip of his tongue and pinched the seal again.

Countless water droplets emerged from the air and the surrounding grass and trees, gathering into the shape of millions of water swords, all shooting towards Xitong.

"Xiao Jingming." Xitong said hoarsely, "Do what you want to do."

"Hehe! I've been waiting for you to say this!" Lu Jingming shouted loudly. He jumped up and went straight to one of them.

Qin Xu was startled, a trace of blood flowed from the corner of his mouth, and the water sword in the air forcibly turned its tip towards Lu Jingming.

Lu Jingming didn't even look at the sharp water swords, he just charged forward. Xitong silently chanted a spell while quickly approaching the men. Most of the water swords evaporated before they could pierce Lu Jingming. Lu Jingming passed through the layers of white mist and threw the man to the ground, "I got you!"

Lu Jingming had several new wounds on his face. He was panting and sat down on the struggling man. Qin Xu wiped the blood from the corner of her mouth with a complicated look. If Xi Tong had been a little slower, at least one water sword would have definitely taken Lu Jingming's life.

One person seized the center of the formation to disrupt their formation, one person broke their spiritual power exchange, and one person provided escort.

Is this what Xitong planned?

Qin Xu spat out the blood in her mouth. As the most important star of the Tiangang Beidou, one of the stars was dragged out of the formation by Lu Jingming. He suffered the greatest backlash. Qin Xu raised her hand and whipped again, saying bitterly, "Xinru! Don't you want to be a human being?"

"What are you hesitating about? Kill him!"

"I haven't thanked you yet." Xitong grabbed the long whip in her hand. Qinxu tried to pull it out with force, but this time she couldn't pull it out.

"Dragon tendons, huh?" Xitong threw the whip away in boredom and walked in front of Qinxu, "I have something I have wanted to do for a long time."

Qin Xu looked at Xitong timidly, like a frightened animal.

Xitong suddenly squatted down in front of Qinxu. Although Lu Jingming and Shen Anzhi didn't know what his purpose was, out of trust, they also lay down on the ground.

“I want to blow up the school.”

Xitong squatted on the ground and hugged his head quickly. At the same time, he set up an aura shield in front of Lu Shen and the other person. In the next moment, a loud bang exploded in the space from the direction of the school gate behind them!

The shock wave of the explosion came faster than the sound. Qin Xu, who was attacked by the backlash of spiritual energy, had never seen such a scene before. He snorted coldly and raised his hands flat in front of his chest, trying to withstand the shock wave.

In an instant, the sky and the earth changed color.

Xitong brushed the dust off his body, coughed out the dust in his mouth and nose before standing up. He looked at Qinxu, whose face was covered in dust due to the shock wave of the explosion, with her white hair stained with blood, and she looked extremely embarrassed.

"Xiaolong, Xiaolong." Xitong said, "You underestimate the biogas explosion."

Xitong said calmly, he waved his sleeves to remove the thin layer of spiritual energy protecting the teaching building, and none of the classroom windows were spared, with glass fragments falling all over the floor. Fortunately, with Xitong's spiritual power protecting them, no one would be killed.

"The methane produced by the decomposition of garbage in a first-tier city in a year is equivalent to five atomic bombs." Xitong said, "Never mind, there is nothing to say to you illiterate people. You don't even know what an atomic bomb is."
