When Zhang Feng walked to the door of the banquet hall, Professor Quirrell stumbled towards the banquet hall with a strong stench, but did not notice Zhang Feng by the door, and as a result, Zhang Feng tripped and rolled into the banquet hall, gasping for breath and saying, "The troll—in the underground classroom—thought you should know." With that, he fell headlong to the floor and passed out.

There was chaos in the restaurant. Professor Dumbledore had to make a few screeching fireworks explosions on his wand's head before everyone fell silent. "Prefect," he said in a deep voice, "bring the students of your academy to the dormitory at once!"

And Zhang Feng, who heard Professor Quirrell's words, had already rushed to the underground classroom at this time.

As soon as he walked into the corridor of the underground classroom, Zhang Feng smelled a foul smell. It was the smell of smelly socks mixed with a public toilet that was never cleaned. Then he heard a muffled grunt and the sound of huge soles dragging on the ground. It was a horrible sight. It was twelve feet tall, its skin dull and gray as granite, and its massive, dumb body resembled a huge pile of mud with a small head like a cocoa bean. Its short legs are as thick as tree stumps, and underneath are flat, thick, calloused feet. The smell emanating from it was disgusting. It holds a thick wooden stick in its hand, which is dragged on the ground due to its long arms. The troll stopped at a door and peeked inside. It wiggled its long ears, made a decision with its small head, and then lowered its head and slowly slipped into the room.

At that moment, two first-year children sprang out of the opposite hallway, it was Harry and Ron, and they turned sideways to the open door, grabbed the key in their hands, slammed the door, and locked it firmly. Their faces flushed with excitement from their success, and they began to run back down the passage.

But as soon as Harry and the others came around the corner, they heard a sound that almost stopped their hearts—a terrible, terrified voice—coming from the room they had just locked.

When Zhang Feng heard this voice, he seemed to have suddenly comprehended teleportation, and in the blink of an eye, he ran to the door that had just been locked. A palm struck out, and the door shattered, but it was Zhang Feng who used the warrior monk's skill - Thunder Light Fist, and it turned out that this was the women's toilet occupied by the crying myrtle.

Zhang Feng looked into the room, Hermione and Zhang Qiu were holding their wands and were dealing with the trolls, but the huge wooden stick in the troll's hand brought them a lot of pressure, and the toilet was already in a mess at this time, and the toilet partition had been destroyed sideways by the big wooden stick in the troll's hand.

Seeing this, Zhang Feng drew his short sword, Ricksat's Elegy, and ran towards the troll. For trolls, physical attacks are far more effective than magical attacks. In front of the sharp short sword, the wooden stick in the troll's hand was not stronger than tofu, and soon the wooden stick in the troll's hand had become a chopping mound, looking at the wood grain, the wooden stick was still beech.

The troll felt that the weight in his hand was not quite right, and looked at the "front stick" with only one wooden handle left in his hand, and it was a little stunned, and its brain probably couldn't figure out why its weapon was gone.

Zhang Feng didn't wait for it, picked up his short sword, and quickly circled the troll's legs. At first, the troll didn't feel it, and when it tried to raise its legs to chase after Zhang Feng, it suddenly found that its legs were not listening. Then it felt the whole world rising, and with a bang, it fell to the ground. Only then did it feel a sharp pain in its legs, and it turned out that Zhang Feng had cut off his legs. It has lost its ability to resist.

Suddenly, there was a loud knock on the door and loud footsteps, and all three people in the room looked up. They didn't realize what a commotion had just happened, it must have been the people downstairs who heard the violent collision and the roar of the trolls. Moments later, Professor McGonagall burst into the room, followed closely by Snape, Quirrell at the end, and Harry and Ron followed. Quirrell glanced at the troll before letting out a feeble sob, sitting on a toilet bowl and clutching his chest.

Snape stooped down to look at the troll. Professor McGonagall looked at Zhang Feng, Zhang Qiu, and Hermione. Her lips turned white. "What the hell are you guys up to?" Professor McGonagall said, with a cold anger in her voice. "You're lucky not to have been killed by it. Why don't you stay in the dorm honestly?"

"Professor, I suppose my sister and friends don't know about the trolls, so I should come and inform them and bring them back!"

Professor McGonagall's face was much better.

"Well, I'll still say you're lucky, there aren't many first-year students who can take on an adult troll. Each of you earned five points for Ravenclaw. I'll inform Professor Dumbledore about this. You can go. ”

A storm passed.
