Gu Wenyu didn't know what this formation was for, and she wasn't sleepy at this moment, her green eyes were staring at the brush in Teacher Zhu's hand.

Mr. Zhu put the brush on the formation, and as the tip of his pen moved, the pattern of the formation was also changing, and the original red and gold lines moved with the tip of the pen.

His movements were extremely slow, and it seemed that each stroke required a great deal of effort. After just a few strokes, Mr. Zhu's forehead was already soaked with sweat, and his hand holding the pen trembled slightly.

Gradually, Mr. Zhu had to stop and rest for a long time every time he painted, but he still had no intention of stopping, it seemed that his purpose was to modify the original formation diagram.

In other words, the original red formation was not drawn by Mr. Zhu, and the reason why he came up to the rooftop was to modify or destroy this formation.

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

Just when Teacher Zhu was seriously revising the formation diagram, Gu Wenyu suddenly smelled the demonic qi in the air and became rich, but Teacher Zhu didn't seem to be aware of it, and was still focusing on the formation diagram in front of him.

Gu Wenyu was alert, she stood up, her two hind legs were tensed, and the hair on her whole body stood up, she knew that something was about to get closer.

The demonic qi became stronger and stronger, Gu Wenyu looked around very vigilantly, and suddenly, a black shadow appeared, and it rushed towards Teacher Zhu who was squatting on the ground at a very fast speed.

The black shadow flickered, it was difficult to capture with the naked eye, and Gu Wenyu also turned on the slow motion mode at the moment when the black shadow appeared, which captured the movement of the black shadow.

Mr. Zhu did not perceive the danger after arriving at him, and he still maintained the posture of holding the pen.

"Meow!" Gu Wenyu sent a police call, and then she kicked the ground with her hind legs, and her body jumped out with a "whoosh".

Teacher Zhu was also startled when he suddenly heard a cat meow, but he only looked in the direction where Gu Wenyu was, because the cat meow came from this direction, and normal people's thinking was to look this side first.

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

At this time, Gu Wenyu had already turned on the slow mode, she was calculating the time, it was not difficult to catch up with the black shadow, but the strength of the black cat 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 was already flying in mid-air, and the black shadow was just a stone's throw away from Teacher Zhu.

"Poof", the black cat flying in mid-air suddenly turned into a human girl, and she shouted anxiously: "Brother!"

Teacher Zhu's pupils slowly dilated, and his eyes were full of disbelief, but with his speed, he couldn't avoid Gu Wenyu's flutter.

At the moment when the demonic black shadow 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 couldn't hit it, and immediately flew over again, Gu Wenyu's slow-motion mode was lifted, Teacher Zhu pushed hard, Gu Wenyu turned over with strength, and then rolled to the side from Teacher Zhu, and Teacher Zhu rolled on the spot, which was able to avoid this blow.

The two separated, and the monster did not pursue Gu Wenyu, but continued to attack Teacher Zhu, this monster had a strange speed, on all fours, like a leopard, but its body appeared from time to time, as if it would disappear at any time.

At the same time as the monster pounced on Mr. Zhu, he took the pen and swiped it in the void, and a golden silk thread ejected out like a substance, hitting the leopard monster, a burst of black mist gushed out, and the leopard monster was in pain, was knocked out, and fell heavily to the ground.

"Whew!" the leopard monster let out a miserable scream, and Mr. Zhu took advantage of this time to stand up.

Mr. Zhu drew a big cross in front of him, and two golden silk threads shot out.

The leopard monster's body showed a strange arc, and it actually dodged.

It looked at Teacher Zhu and Gu Wenyu from a distance, and seemed to hesitate for a while, and then spewed out a stream of black gas from its mouth, and the body of the leopard monster was virtualized, and it was far away, and it disappeared into the night in a breath.

Teacher Zhu can't catch up if he wants to, although Gu Wenyu can turn on the slow mode, but counting her remaining energy, she only has one last chance today, and she doesn't have the slightest combat power, even if she catches up, it's just a death.

So neither of them moved, and just watched the leopard monster leave.

And that black gas fell on the formation, and it quickly dyed the formation into a pitch-black color, and the formation disappeared into the concrete floor again.

Teacher Zhu looked at Gu Wenyu, her eyes were full of doubts, Gu Wenyu also knew that this matter could not be hidden, she also looked at Teacher Zhu, and the two were relatively speechless.

In the end, it was Teacher Zhu who was the first to speak, and he asked with a strange expression: "You, are you a demon clan?"

"Huh?" Gu Wenyu's face was inexplicable, "What demon clan?"

Teacher Zhu frowned, he didn't look like Gu Wenyu was pretending to be stupid, so he asked again: "Aren't you a demon clan?

It's no wonder that Teacher Zhu has such questions, in the afternoon, Gu Wenyu pestered Teacher Zhu to ask some questions that have no beginning or end, and appeared on the rooftop of the teaching building at night, disguised as a black cat, which doesn't look like a coincidence.

Gu Wenyu was suddenly questioned like this, and he was also a little unhappy in his heart.

"Teacher Zhu, shouldn't you say thank you first? I risked my life to save you!" Gu Wenyu said angrily.

Teacher Zhu's face is not very good, if it weren't for Gu Wenyu saving his life, it is estimated that at this moment, Teacher Zhu would directly use that brush to draw on Gu Wenyu's body.

After all, the demon clan is not a good stubble, and Mr. Zhu doesn't want to risk dealing with the demon clan.

But he held back for a long time, and finally thanked him, and then said in a relatively soft tone: "This ...... Classmates?"

Teacher Zhu paused, as if he thought it should be called right, so he continued to ask, "Who was the black cat just now?"

Gu Wenyu replied briskly: "It's me." ”

Teacher Zhu: "......" Isn't this a demon clan?

Gu Wenyu knew that Teacher Zhu must have misunderstood again, so he quickly explained: "That black cat is indeed me, but I am really not a demon clan. That...... That should count, uh...... One of my abilities. ”

Teacher Zhu raised his eyebrows again when he heard this, and said, "Soul Power Awakener?"

Gu Wenyu's face was full of doubts: "Soul Power Awakener?
