The main room was crowded with scientists, who were chattering and arguing.

The sound of the door opening did not even interrupt their thoughts until...

"This equation is wrong. The number of hydrogen atoms in this material is eighteen..."

Gu Nanzhi's voice woke up an old man who was busy calculating.

"I really wrote it wrong, thank you for reminding me!"

The old man corrected his mistake immediately, and then he realized that the figure standing next to him had not moved, so he raised his head...

It's no big deal to look up.

Next second.

The old man stood up with a whoosh.

"Mr. Gu!"

The scientist, who is over sixty years old, already has gray hair on his temples.

But he stood respectfully in front of Gu Nanzhi, looking at her with eyes full of longing and a little uneasiness.

Ahhhh!

Mr. Gu is back!

Mr. Gu discovered that he had just written an equation incorrectly. Mr. Gu...

You won't dislike him, right?

Many thoughts flashed through the old scientist's mind in an instant, and he was almost ashamed to death!

at the same time.

The other scientists who heard his voice reacted and immediately stopped what they were doing and looked towards Gu Nanzhi.

"Mr. Gu!"

"It's really Mr. Gu! Mr. Gu is back!"

"Mr. Gu, I have a question that I would like to ask you. Could you please..."

"Mr. Gu, I have a question too..."

“…”

“…”

After a simple greeting, a group of scientists immediately surrounded Gu Nanzhi.

Especially Yu Dongchuan and Li Xuewei.

"Mr. Gu, I don't understand two things. Please give me some advice!"

Yu Dongchuan squeezed in front of the crowd with two pieces of paper and said in a deep voice, "Well, the lithography machine uses laser as the light source, and the material of the lithography machine..."

“…”

Gu Nanzhi answered Yu Dongchuan's questions in detail. When Yu Dongchuan asked about the raw materials, Gu Nanzhi replied resignedly, "Don't dwell on it. We don't have probe materials that can improve laser performance and allow it to be used in photolithography machines in Xiaguo at present!"

"What should we do then?"

Upon hearing this, Yu Dongchuan's face darkened immediately, and he said in a deep voice, "We calculated various data on that material and concluded that even if we use synthetic materials, we currently don't have the raw materials needed to synthesize that material!"

"Mr. Gu..."

As he spoke, Yu Dongchuan looked up and said anxiously, "Since you are sure that we in Xia Country don't have that material at the moment, then you must know where to find it, right?"

"Um."

Gu Nanzhi nodded without comment.

She could even reveal to Mr. Xue the location of the materials for upgrading the mushrooms, so there is no reason why she wouldn't dare to tell him about the materials for upgrading the lithography machine!

After all, those rare raw materials already exist in this world, just waiting for someone to mine them. What's more, some people have already mined them...

At a time like this, it wouldn't be a big deal for Xia Guo to go there in advance to get a piece of the pie, right?

It won't destroy the balance of the plane.

"Where is it? Mr. Gu, do you know where the raw materials are?"

Upon hearing this, Yu Dongchuan said excitedly, "No matter where the raw material is, no matter what the price is, we must find a way to get it!"

If they get that kind of raw material, they will have the raw materials to upgrade the lithography machine!

The upgrade of the lithography machine means that they are ahead of the Western world and have mastered the most advanced science...

"The raw materials are in the war-torn rainforest..."

Upon hearing this, Gu Nanzhi gave the name of the country.

It was a historically permanent war zone.

Because of their isolation and tribal existence, they rejected all foreign cultures and have always been in a primitive state of war, living on hunting, with constant tribal conflicts, death and bloodshed...

In her previous life, Gu Nanzhi had also gone there in person for some rare materials...

It was during that trip that the hot and humid rainforest climate, the insects and ants everywhere, and the poisonous plants almost cost her her life.

The country won't allow her to take any risks!

She only stayed in there for three days before she was knocked unconscious by the guards and forcibly escorted out, without ever getting close to the hinterland.

“It’s actually in that place!”

Yu Dongchuan was also shocked when he heard this. "Nine out of ten people go to that place and never return. If the raw materials are really only available there, then it may not be that easy to get them..."

He also studied abroad when he was young, and was well-informed and knew about the existence of that war-torn country.

But it’s really dangerous there!

The other scientists present were also knowledgeable people. When they heard the place name mentioned by Gu Nanzhi, their expressions instantly became solemn.

"If science wants to develop, it must continue to make breakthroughs!"

"Isn't it just the rainforest war zone? I'll take people there!"

"Oh my god! I'm young and strong, so I have a better chance of getting out alive!"

“…”

“…”

Watching the scientists arguing, Gu Nanzhi sighed and stepped aside.

But Li Xuewei appeared in front of him at the right time.

"Mr. Gu."

Because of the offense he had done to Gu Nanzhi, Li Xuewei felt a little awkward when he saw Gu Nanzhi again.

"If you don't understand something, just ask."

Gu Nanzhi was amused by the young lady's hesitant expression and said, "Since I have accepted your call of sir, how can I not teach you anything?"

"Can I really ask?"

Li Xuewei was immediately delighted when he heard this, and then...

Then he took out a small notebook from his pocket.

A small notebook just one or two centimeters thick!

A little notebook full of questions!

"Mr. Gu, I have written down all the questions I don't understand here. I have asked all the professors in Xiake Institute except Mr. Liu, and I wrote down the questions they couldn't answer!"

Li Xuewei held the small notebook in his hand, looking studious and curious, "Please help me, Mr. Gu!"

Gu Nanzhi heard: "!!!"

I took a look at the thick little notebook filled with questions.

He looked at Li Xuewei again.

"Ask again!"

Gu Nanzhi said in a deep voice.

"What?"

Li Xuewei was stunned.

"Can you please ask again? Can you really ask?"

Li Xuewen stared at her blankly and repeated, "Can I really ask?"

Gu Nanzhi couldn't wait and said firmly: "No!"

Li Xuewei: “!!!”

He froze on the spot as if struck by lightning.

"Do you really think I'm the prime minister? Can a belly as big as this hold a boat?"

Gu Nanzhi glared at Li Xuewei and said angrily, "You just offended me and you come to ask me questions one by one. You want to disturb my sleep? You wish!"

As she spoke, Gu Nanzhi turned to look at the other scientists in the room under Li Xuewei's shocked gaze.

"Everyone go to sleep! Health is the capital of revolution. If you really overwork yourself, don't expect me to treat you. I'm very busy!"

Everyone heard: "..."

After saying that, Gu Nanzhi turned around and walked out. When he passed by Li Xuewei, he snorted coldly.

"Come back to me with the notebook when you wake up!"
