Lin Xinghe did not know where this huge green head came from. It did not roll fast, but when it hit the ground, the impact was silent.

It rolled around blindly in the huge city for an hour, stopping every so often as if it were searching for something.

Lin Xinghe hypothesized why this metropolis was like an empty city after 10 pm—the inhabitants seemed to be hiding from this green head.

Lin Xinghe flew to a high altitude and did not bother to follow the green head.

She took out her phone and checked out the photos and videos she had just taken.

When playing the video, she accidentally made a little noise. The green head instantly detected it, and, flying much faster it rolled, approached  her in the blink of an eye.

But she was wearing an invisibility cloak and held her breath, and the green head remained stationary in the air for a few seconds before rolling down again and continuing to wander the city streets.

Lin Xinghe enlarged a photo, and the previously jocose audience also could not help but sharply draw in their breath.

Beneath the green light on the screen, there was an ocean of ghostly faces.

Lin Xinghe calmly zoomed in and out, adopting a thoughtful look.

The audience began to discuss.

【Ah, what is this thing?】

【After experiencing the previous exam, I think this is nothing for Lin Xinghe. It’s not as scary as the five-mouthed Xiao Xue Ji at the beginning!】

【This exam feels pretty easy.】

【Yes, the green head looks quite weak and can’t even detect SL. It just rolls around the city quietly without destroying anything …】

Lin Xinghe stashed her phone, picked up a rock, calculated the distance, and stoned the green head.

The stone flew close to the head, but thick black hair abruptly sprouted from the head and wrapped itself around the whole head until the eerie green light no longer shone through. The stone smashed against the hair-wall, the crisp impact ringing through the air.

Once the stone fell to the ground, the tightly wrapped hair slowly revealed a slit. In the dark night, the slit, leaking green light, was eye-catching. The whole green head slowly rotated until that slit faced the stone on the ground.

Also at this time, the slit issued a shocking hissing sound.

A black lock of hair shot up, curling around the stone and raising it into the air.

A thin lock, set in the middle of the stone like a snake, slowly, layer by layer, rolled across the whole stone. A blast sounded, the hair loosened, and rock dust drifted like snowflakes.

Also at this time, not far down the alley came a song.

The green head instantly turned, and it flew towards the alley.

Lin Xinghe was about to follow, and found that from the other side of the alley also came a song, and in just a minute, different songs sounded in all directions.

The green head flew from the east to the west and then to the south like a brainless fly.

At the same time, a bald head suddenly emerged from the nearest tall building, its owner waving a cell phone with the flashlight on, as if gesturing to her.

Lin Xinghe was slightly stunned. She donned the invisibility cloak, so  no one should be able to see her.

The bald head suddenly raised a tablet.

Words flashed across the tablet screen in large font, forming several sentences:

Come in while the devil is attracted by the song! I see you! I know you’re invisible!

Lin Xinghe was a little surprised, and after some contemplation, she flew to the tall building on her magic broom.

It was an office building.

Despite the hour, many people worked overtime.

The bald head was a delicate, gentle girl, smiling with curved brows. She was the only one in the corridor as she held the tablet by the window.

Lin Xinghe remained invisible, but when she entered, the girl seemed to notice and closed the window.

Lin Xinghe was a little surprised.

And at this time, the bald girl said, “There are cameras here. Come with me to the bathroom, it’s not monitored.”

After entering the bathroom, the bald girl asked, “Are you here now?”

Lin Xinghe hummed.

The bald girl immediately locked the door of the bathroom.

Lin Xinghe took off her cloak now, but she was still in disguise.

She asked, “How did you know I was invisible?”

The bald girl blinked, seemingly enthusiastic. Her smile was overflowing out of her eyes, and she said, “I just happened to see you fly into the alley and then disappear. I’ve been watching you. After the devil appeared, I guessed that you might want to go and defeat it, and I monitored its whereabouts. I prepared the song in the alley. The devil has no weaknesses, and I was afraid you wouldn’t be able to defeat it.”

Thinking of something, she asked, “You are a witch, right! Everyone who rides  a broom is a witch! I always wanted to be a witch! Can you take me as your apprentice?”

Lin Xinghe didn’t expect there to be youthful girl NPCs in this world, but without thinking, she said, “Congratulations, young lady! You located me, so you proved your destiny. As long as you pass my test, I will take you as an apprentice. What is your name?”

“Yu Ying.”

“Do you accept the witch’s test?”

Excitement in her shining eyes, Yu Ying said, “I accept!”
