National Doomsday: I am the master of viruses, I evolve by eating poison

The walls of the corridor of this biochemical factory are made of large pieces of special materials that can withstand hundreds of tons of impact.

Let's pry it away first.

Selling it should make more money than directly extracting it as energy.

After a while, the metal materials in the entire corridor were almost pried off and put into the system.

Tian Mengxue's vital signs were not so weak.

Su Yunfei thought about it, put her on his shoulders and took her out.

This would not affect him much, and he could move freely.

In fact, if possible, he wanted to clamp her under his armpit.

After thinking about it, he decided not to.

His strength was so great, don't clamp her flat...

Su Yunfei felt the soft touch on his body, silently pursed his lips, and felt a little uncomfortable.

The posture of being carried might not be very comfortable for Tian Mengxue.

After Su Yunfei strode out for a while, he heard her low cough.

Anyway, Karen was in the wolf's claws, so Su Yunfei was not in a hurry. He slowed down and asked, "Awake."

Tian Mengxue woke up, but couldn't speak for a while.

Through the system, she said to Su Yunfei, "Brother Yun... we are out..."

Su Yunfei said, "Yes! My injury has healed, of course I can come out."

After a moment of silence, Su Yunfei said, "Thank you this time."

This upgrade was a mistake, but the final result was good.

If it weren't for her mental healing potion, he wouldn't have successfully upgraded his brain width so quickly.

Although he couldn't trust her completely, his trust in her increased a lot after this incident.

"It's okay..." Tian Mengxue coughed twice again and said, "It's a bit uncomfortable like this..."

His shoulder bones were very hard, poking her stomach, which was very uncomfortable.

It hurts a bit.

"It's really troublesome."

Su Yunfei said this, stretched out his hand, turned around, and moved Tian Mengxue to his back.

He stretched out one hand behind her and held her legs.

"Is this okay?"

"Hmm..." Tian Mengxue made a mosquito-like sound.

Now she was lying on Su Yunfei's back, feeling the steam rising and warm.

Her cheeks were flushed.

Su Yunfei walked out slowly, and with a sweep of his mental power, he could detect everything within a hundred meters around him.

There was no danger.

He was not nervous at all. He smiled and said casually:

"Little sister, saving me and me saving you are two different things. You were almost poisoned just now, and I spent 100 million on the antidote."

"Besides, a genius like you, so beautiful, is simply priceless... Your life is barely worth 100 billion energy points."

"I'll give you a discount, half price, 50 billion!"

"So, you owe me 50.1 billion now, do you understand?"

Tian Mengxue was originally sleepy and about to fall asleep, but she opened her eyes wide and blinked.

Su Yunfei was so shameless that she was speechless.

Then she couldn't help but chuckle.

He must be teasing her.

Su Yunfei said casually again:

"If you tell me the past you have concealed, this debt can be written off."

Silence.

After a few seconds.

Tian Mengxue's soft and gentle voice slowly sounded in his ears:

"Because I was born first, you, Brother Yun, could save me."

"Since 'I' is worth 100 billion--"

"I gave 100 billion, and you only gave 50.1 billion..."

"Brother Yun, you owe me 49.9 billion now~"

Hearing this, Su Yunfei stopped.

This time, it was his turn to be slightly stunned, and then laughed.

Su Yunfei laughed: "You often get full marks in math, right?!"
