Chapter 199：

As an interstellar human being 3000 years later, Gu Ruyun knows a lot of scientific knowledge and information technology that is completely incomprehensible to the earth today.

Logically speaking, wanting to make money is easy.

But what kind of technology, Gu Ruyun didn't dare to come up with it at such a time, especially the technology in her mind. In addition to medical aspects, the most important thing is the knowledge of those military weapons mecha warships.

Whether it is the simple production of mecha warships or those particle guns and light energy weapons, any technology is not suitable for the earth that is now at peace with the world.

Once this kind of weapon is taken out, it can immediately change the political status of a country and make the country's military strength take a big step forward. As long as it is produced, the entire earth will immediately become chaotic.

Let this originally peaceful planet be shrouded in war in an instant, and ordinary people are panicked and uneasy all day long.

This is definitely not what Gu Ruyun wants to see!

Especially someone like her who just walked off the battlefield has almost a disgust for war.

The most important thing is that once these technologies come out, it will involve her own safety today.

Even if her current physical quality has reached the peak level of her previous life, and her mental strength is strong enough to affect communication signals, a few atomic bombs are enough to send her to the sky.

so……

Whether in terms of his own safety, his own hobbies, and the wishes of the original owner of this body, it is the most appropriate and safe way to be a doctor who treats and saves people just like in his previous life.

"But it's safe to be safe, and I really don't have any money!" Gu Ruyun almost wanted to leave a tear of sympathy for himself.

Undocumented is difficult...

She had a deep understanding of these words.

After all, not everyone has such good luck. They can casually pick up a few terminally ill patients on the road. It just so happens that she can be cured, and I believe that she is such a stupid and rich unlicensed doctor.

Gu Ruyun raised his hand and wiped his cheeks, and angrily extracted Xiaobai, who was trying to sleep on her bed, and put it on the top of the cabinet beside him.

Xiaobai: "Meow meow meow meow???"

There is a comfortable cat litter, but it is not allowed to sleep! Obviously there is a comfortable big bed, but it is not allowed to lie down!

So why did this female devil pick it up again? !

When it used to wander outside, it still had some tattered clothes and cardboard boxes! Now I can only sleep on the top of the cabinet! QAQ! bully meow!

Xiaobai was grinding her claws in the cupboard with grief and indignation, but Gu Ruyun completely ignored his plans. In the past, when the battlefield was full of flames, she could fall asleep. What is this little sound of grinding her claws?

Gu Ruyun slept well all night.

After having breakfast early the next morning, Gu Ruyun left the dining table while Xiao Qirui glanced at her from time to time at the dining table, and drove to school with Yoko.

Before anyone entered the school gate, Gu Ruyun was baptized by a gaze that was even stronger than yesterday. At the same time, Yangzi, who had been sitting in the driver's seat of the car, was also treated by this treatment. In the car, Shi Shiran drove away without feeling the scorching gazes from other students.

Gu Ruyun walked on the road, glanced around the crowd lightly, and ignored these strange expressions, some slightly sympathetic eyes, and walked in the direction of the classroom.
