Gu Wenyu didn't know what this formation was used for, so she was no longer sleepy now. Her green eyes stared at the brush in Teacher Zhu's hand.

Teacher Zhu tapped the brush on the formation. As the tip of his pen moved, the pattern of the formation was also changing, and the original red and golden lines moved with the tip of the pen.

His movements were extremely slow, as if every stroke would cost him a lot of effort. With just a few strokes, Teacher Zhu's forehead was already covered in sweat, and his hand holding the pen was trembling slightly.

Gradually, every time Teacher Zhu draws a stroke, he has to stop and rest for a long time, but he still has no intention of stopping. It seems that his purpose is to modify the original array diagram.

In other words, the original red formation was not drawn by Teacher Zhu. The reason why he came to the rooftop was to modify or destroy the formation.

Gu Wenyu didn't know the formation, but just looking at Teacher Zhu's difficult appearance, he knew that this was definitely not an easy task.

Just as Teacher Zhu was carefully revising the array diagram, Gu Wenyu suddenly smelled the demonic energy in the air became rich, but Teacher Zhu seemed to have no idea and was still focused on the array diagram in front of him.

Gu Wenyu felt alert. She stood up, her hind legs stretched, and her hair stood up all over her body. She knew that something was about to get closer.

The demonic energy became stronger and stronger. Gu Wenyu looked around with great vigilance. Suddenly, a black shadow appeared. It rushed towards Teacher Zhu who was squatting on the ground at an extremely fast speed.

The black shadows appeared and were difficult to capture by the naked eye. Gu Wenyu also turned on the slow release mode at the moment when the black shadow appeared, and then captured the movement of the black shadow.

Teacher Zhu did not notice the danger from behind, and he still maintained the posture of holding the pen.

"Meow!" Gu Wenyu issued a warning, then she kicked the ground with her hind legs and jumped out with a "swoosh".

Teacher Zhu suddenly heard a cat's meow, and was also shocked, but he looked up and looked in the direction where Gu Wenyu was, because the cat's meow came from this direction, and normal people's thinking always looked here first.

Gu Wenyu was anxious. Seeing the shadow getting closer and closer to Teacher Zhu, she wanted to save Teacher Zhu, she had to push Teacher Zhu away before the shadow.

At this time, Gu Wenyu had already turned on the slow release mode. She calculated the time and it was not difficult to rush before the black shadow, but the black cat's strength was not enough to push away an adult male like Teacher Zhu.

So Gu Wenyu had to transform into a human form. At this moment, the black cat had already pounced in the air, and the black shadow was just a short distance from Teacher Zhu.

With a "puff", the black cat that flew into the air suddenly turned into a human girl. She shouted anxiously: "Brother!"

Teacher Zhu's pupils slowly dilated, his eyes full of incredible expressions, but at his speed, he could not avoid Gu Wenyu's flying pounce.

Just as the black shadow with awesome evil spirit touched Teacher Zhu, Gu Wenyu flew to the ground at the same time, "Dangerous!"

Teacher Zhu fell to the ground on his back, and he finally saw the black shadow behind him.

The black shadow failed to hit, and immediately rushed over again. Gu Wenyu's slow release mode was lifted. Teacher Zhu pushed hard, and Gu Wenyu took advantage of the force to turn over, and then rolled aside from Teacher Zhu. Teacher Zhu rolled on the spot, barely avoiding the attack.

Gu Wenyu was full of doubts: "Soul power awakened? What is that?"
