In fact, as soon as they returned to school, they went to the principal's office to find Cheng Wenshan. After living in the oxygen-deprived post-apocalyptic world for so long, they had become accustomed to listening to the principal in everything.

But when the two first entered the office, they searched the entire small space but couldn't find a single person.

"Where is he?" Wu Xiuzhu couldn't explain her feelings at that moment. She knew she was very emotional and wanted to find Cheng Wenshan immediately and confront him about why!

Because in the beginning, the idea of ​​having her suck human blood to maintain the city's protective shield was proposed by Cheng Wenshan!

She wanted to ask him face-to-face why he had harmed her. He could have used the crystals to maintain his energy, so why did he force her to drink human blood and turn into a monster?!

Qi Ming was calmer than her and had already figured it out: "He must have run away, right?"

He went straight to the warehouse next door, where all the oxygen cylinders they had collected from the entire town were stored.

Sure enough, they were all gone.

“There’s a lot of stuff here, enough to fill at least a pickup truck. He… has been planning this for a long time?” Wu Xiuzhu muttered to herself, but she couldn’t understand, “Why did he run away?”

Qi Ming shook his head; he couldn't figure it out either.

Just then, a series of "tap-tap" footsteps came from the corridor behind the two.

Both of them thought that a zombie had approached, and their backs tightened instantly. They turned around at the same time.

But then they saw Cheng Wenshan, a man with a big smile on his face, standing behind them, arms crossed, greeting them: "You're back?"

Their tone was calm, as if the thousands of zombies attacking outside were just an illusion.

Wu Xiuzhu immediately rushed forward, her hands clenched into fists, her eyes bloodshot and wide, and angrily questioned, "Principal Cheng! What are you after? Why did you lie to us?!"

"Oh?" Cheng Wenshan chuckled. "What did I lie to you about?"

"I don't need to drink blood, why did you make me suck human blood?!" Wu Xiuzhu said, unable to contain her despair. She was a normal person, why had she become a blood-sucking monster? It was all his fault! He had lied to her and ruined her life!

"Hehe, I'm not lying to you. I'm doing this for your own good. Besides, I told you the truth back then. What, didn't you tell Xiuzhu?"

Cheng Wenshan remained calm and smiling, but his next words were directed at Qi Ming.

Upon hearing this, Wu Xiuzhu was even more devastated. She stared at her boyfriend in disbelief, her lips trembling as she asked, "What? You...you know...?"

"You've been hiding this from me?"

She spoke these words slowly and deliberately, using all her strength to utter them!

Qi Ming's eyes darted away, his face filled with sorrow, and he whispered in defense of himself, "I...I don't want you to be sad..."

But before he could finish speaking, Cheng Wenshan suddenly interrupted: "I said before that I would let the two of you make a choice. I was more optimistic about Qi Ming. After all, he is a man, and his energy is naturally stronger than that of a woman. But I didn't expect that you would be the one to step forward in the end. I thought you knew the truth."

"I don't know!" Wu Xiuzhu felt her ears ringing. She couldn't think straight anymore. She only knew one fact: her boyfriend, whom she had relied on and loved with all her heart and thought would support and cherish her through the oxygen-deprived apocalypse, had lied to her, or even betrayed her!

Cheng Wenshan still felt that it wasn't enough, and chuckled from behind: "Don't get too excited, it's fine as it is. Now that your superpowers are strong, you don't need to be afraid of those zombies outside at all."

With bloodshot eyes, Wu Xiuzhu hopped straight toward Qi Ming. The two instantly began to wrestle, but Qi Ming was no match for Wu Xiuzhu. In just one exchange, a sharp weapon pierced through his abdomen!

Wu Xiuzhu killed him with her own hands.

Cheng Wenshan seemed quite surprised, visibly taken aback for a moment, but then he laughed happily and rubbed his hands together excitedly: "Good! Good! Good!"

"You're great! You haven't let me down! Look at yourself, aren't you much stronger now?! Xiuzhu, let's go, I came here especially to pick you up!"

Cheng Wenshan extended a very warm invitation, and his attitude was so good that people who didn't know the situation would think he was a kind and approachable old man.

"The car is downstairs. Let's leave now. There are too many zombies here. It's not safe."

Wu Xiuzhu stared blankly at her hands, the thrill of killing with her own hands overwhelming her reason. A voice in her head screamed, "Kill him! Kill him! He's the culprit!"

But as soon as she made a move, everything went black before her eyes, and she collapsed limply, unconscious.

Beside him, Cheng Wenshan withdrew his hand, revealing a sinister, triumphant smile.

Meanwhile, Cheng Zhen, after continuously opening the portals of time and space to send away more than a thousand students, exhausted his supernatural abilities and collapsed to the ground.

"Boss, boss?" As the sky began to lighten, Yu Fen's energy from his light shockwave began to recover. He killed a zombie and turned around to see Cheng Zhen like this, which made him feel uneasy.

"I'm fine, I just need a rest. Be careful!" He had barely finished speaking when a zombie suddenly appeared behind Yu Fen.

Fortunately, he was alert enough to dodge first, and then the light shockwave killed him directly.

Yu Fen returned to the battle with all his might, and Cheng Zhen dared not delay any longer. He reached for the crystals on his body, but found none.

Oh no, all the crystals I brought with me were used up when I opened the portals one after another!

Just then, Jiang Wan suddenly placed a bag of colorful crystals in front of him.

Upon seeing this, Cheng Zhen was overjoyed. Ah, he knew this woman cared about him.

"Xiao Shu and Xin Xin dug it."

Jiang Wan said, gesturing for him not to be polite, "They hadn't gone to sleep when we got back. Knowing that you saved so many people this time, they insisted on contributing their share, so they brought out all the crystals they had mined these past two days."

Cheng Zhen silently picked up a crystal, absorbing its energy while secretly grumbling. Although he was happy with the crystal that the two kids had specially given him, he wanted even more the one that she had specially dug for him!

Jiang Wan pursed her lips: What are you thinking? How could she have time to dig for this stuff?

"Xiao Shu told Xin Xin that this was a special gift for everyone."

Cheng Zhen paused, holding the crystal. Half of the joy in his heart vanished. Damn it, what am I going to do when my two kids aren't close to me?!

But he had no time for sentimentality. After recovering a little, he joined the battle, forced back a few zombies, and then took the opportunity to open the portal again to send the adults away.

They fought and retreated, until only their own troops and the dozen or so teachers who originally belonged to the school remained, all of whom were forced to retreat to the office building behind the teaching building.

Outside, there were hordes of zombies, and the number was increasing. Yu Fen gritted his teeth: "What's wrong with these zombies? They're like they've been given stimulants!"

Suddenly, a teacher behind them cried out in alarm, "Something terrible has happened! Qi Ming is dead!"
