To Pang Xuelin's surprise, when he went to CERN, he also met Edward Witten, who was attending a meeting at CERN.

In the real world, the two don't have much to do with each other, but in the world of rural teachers, the two have been friends for many years.

This meeting, under the deliberate guidance of Pang Xuelin, Edward Witten soon had a feeling of hating to meet him late.

Theoretical physics has been circling in the circle of the Standard Model for many years, experiments have not kept up with the progress of theoretical research, and string theory cannot be verified until the Year of the Monkey.

Therefore, although Pang Xuelin only stayed in the world of rural teachers until 2002, there was still no obstacle when communicating with Witten in 2020.

Pang Xuelin stayed at CERN for three days, and before leaving, he invited Witten to come to Jiangcheng if he had time.

Witten agreed.

It wasn't until early September that Pang Xuelin ended his trip to Europe and flew back to Beijing with Yao Bingxia.

As a result, as soon as he got off the plane, Pang Xuelin received a congratulatory call from Liu Tingbo: "Hey, Professor Pang, congratulations!" ”

Pang Xuelin was slightly stunned and wondered: "What's wrong?" ”

Liu Tingbo said with a smile: "Just now, the Chinese Academy of Sciences has announced the public list of new academicians in 2020 on the official website, and your name is on it, if nothing else, you will become a member of the academicians of the Department of Mathematical Physics of the Chinese Academy of Sciences at the end of the year!" ”

"Huh?!"

Pang Xuelin was slightly stunned and said with a smile: "Dean Liu, thank you for notifying." ”

Liu Tingbo said with a smile: "Okay, it is estimated that many people will call you to say hello next, so I won't say more." ”

"Well, that's it first, bye-bye!"

Hanging up the phone, Pang Xuelin shook his head with some emotion.

But he wasn't surprised.

With two world-class conjecture proofs in hand, plus a set of Ponzi geometry theories that have had a revolutionary impact on the entire algebraic geometry system, you can't become an academician.

In the eyes of others, the highest honorary title in China's scientific community, which may require a lifetime of struggle, is within reach for Pang Xuelin.

Yao Bingxia on the side was curious: "Brother Xiaolin, what's wrong?" ”

Pang Xuelin said with a smile: "I have been selected into the public list of academicians of the Chinese Academy of Sciences!" ”

"Ah, that's great!"

Yao Bingxia looked even more excited than Pang Xuelin: "Let's go, Brother Xiaolin, let's go home first, I'll call back later and ask my mother to cook a good table of good dishes in the evening, and we'll celebrate." ”

Sure enough, on the way to Yao Bingxia's house, Pang Xuelin's phone rang almost non-stop.

Xu Xincheng, President of Jiang University, Zhang Deye, President of the Chinese Mathematical Society, Qiu Chengtong of Tsinghua University and other bigwigs called one by one, in addition, Xu Xingguo, Li Changqing and other bigwigs who have cooperated with Pang Xuelin also called to congratulate Pang Xuelin.

Some who did not get through the phone expressed their congratulations to Pang Xuelin through WeChat.

These include students from the Ponzi Geometry Workshop and researchers from the Center for Carbon Nanomaterials Research.

Pang Xuelin replied to these people one by one and expressed his gratitude.

However, when he saw the latest WeChat, Pang Xuelin's face was slightly complicated.

The sender's name is [Miss Xin], and the message is only two words: "Congratulations." ”

Pang Xuelin knew that this was Qi Xin's WeChat.

Since she left her job and went abroad, the two have not been in touch for nearly half a year.

Pang Xuelin thought about it and replied with two words: "Thank you!" ”

……

Yao Bingxia is about to start school and enter her senior year.

After staying in the capital for a day, Pang Xuelin said goodbye to Yao Bingxia, who was reluctant to fall in love, and returned to Jiangcheng.

Jiangcheng University is about to open, and Pang Xuelin, who is about to change from Professor Pang to Academician Pang, has returned to his busy state in the past.

On the evening of September 5, 2020, after reading the latest experimental report sent to him by the meter-level carbon nanotube team, Pang Xuelin yawned and was just about to go to bed, when suddenly, the sound of the system suddenly sounded in Pang Xuelin's mind.

"Please note that the plot of the "Three-Body Problem" world has been repaired, and the plane of "Dark Forest" will be opened in half an hour, please prepare accordingly."

The expression on Pang Xuelin's face suddenly became solemn.

Today is the first anniversary of his system, and Pang Xuelin didn't expect that the world of "Three-Body Problem", which had not moved for a long time, would finally open again.

But this time, what he has to experience is the second part of the "Three-Body Problem" series - "Dark Forest".

"Dark Forest" spans more than 200 years, from the first year of the Crisis Era (2007 AD) to the 208 years of the Crisis Era (2215 AD)

According to the calculation of 1:10,000 between plane time and real time, he will sleep in reality for at least nearly a week.

Pang Xuelin pondered for a moment, then took out his mobile phone and made a call to his father Pang Yongnian.

"Xiaolin, it's so late, is there anything to do with me?" Pang Yongnian's gentle voice came from the phone.

Pang Xuelin pondered for a moment and said, "Dad, there is something, I want to ask you for a favor." ”

"What's the matter?" Pang Yongnian said with a smile.

Pang Xuelin said: "Tomorrow at noon, you and your mother come to my school apartment, if I haven't woken up, you will send me to the hospital, let the doctor give me an infusion, to ensure the supply of nutrients to my body, if I am fast, a week, if slow, it may take ten days and half a month to wake up......"

Pang Yongnian's tone suddenly became serious, and he said, "Xiaolin, what's the matter?" ”

Pang Xuelin was silent.

After a while, Pang Yongnian's tone softened: "Can't you say it?" ”

Pang Xuelin said: "Dad, in short, you can rest assured, I will be fine, remember what I said, in addition, don't tell anyone that we are on the phone, including Mom." ”

"Your mom is right next to me......"

“……”

Pang Yongnian said: "Okay, your mother wants to talk to you." ”

Soon, her mother Mei Yuqing's crying voice came from the other end of the phone: "Xiaolin, what the hell is going on with you, don't scare your mother." ”

Pang Xuelin smiled: "Mom, don't worry, it's okay, I'll sleep for a while, you just send me to the hospital to take care of me, I will wake up soon, don't worry." ”

"You are like this, how can your mother not worry......"

Pang Xuelin said: "Mom, it's really fine, and don't tell anyone that I and you are on the phone, this is very important!" ”

"Okay, okay...... Mom knows! ”

Soon, the phone was back in the father's hands again.

Pang Yongnian said: "Xiaolin, you ...... yourself If there's anything inconvenient to say, Dad won't ask. Dad only hopes that you can take care of yourself, don't work too hard, and if you feel too tired to do scientific research, go back to work. ”

Pang Xuelin smiled: "Dad, I know, it's not early now, I'm going to sleep too, you and Mom rest early, good night!" ”

"Good night!"

Not long after hanging up the phone, the voice of the system sounded in Pang Xuelin's mind again: "The dark forest plane will be opened in ten seconds, the host please be ready, ten, nine, eight, seven, six, five, four, three, two, one......"

……

Pang Xuelin opened his eyes suddenly, he was lying on the bed in the bedroom of Xishan Villa, and it was already bright outside.

In his mind, the task that the system instilled in him appeared.

Plane: Dark Forest

Identity: Pang Xuelin, 28 years old, former ETO member, is currently a professor in the Department of Mathematics of Beijing University

Title: Inheritor of Civilization

Mission 1: Become a wall-facing person and destroy ETO completely

Mission 2: In the Doomsday Campaign, keep the stellar battleship for humanity as much as possible (the more starships you keep, the greater the reward)

Task 3: Find a way to evade Tomoko's surveillance

(For the above three tasks, the completion of two tasks is considered as the completion of the tasks)

Reward: Unknown (depending on mission completion)

Pang Xuelin picked up the straight mobile phone on the bedside table and looked at the time, 8:07 a.m. on November 5, 2007.

There is a bathroom in the bedroom and all kinds of toiletries.

Pang Xuelin brushed his teeth and washed his face, and when he came downstairs, the nanny in the villa had already prepared breakfast for him.

Millet porridge, pickles, and steamed buns are simple but have a unique taste.

Pang Xuelin walked out of the villa and came to the courtyard, and the guard took the lead and stopped Pang Xuelin and said, "Mr. Pang, you are still in danger now, it is best not to go out." ”

Pang Xuelin smiled and said, "Am I under house arrest now?" ”

The guard opened his mouth and said, "Mr. Pang, if you really want to go out, I can help you ask your superiors for instructions." ”

"No need to ask......"

A familiar voice came from outside the courtyard, Pang Xuelin turned around, and saw Da Shi walking towards him with a big grin.

"Great history, good morning!"

"Brother Pang, morning! Hey? Dashi glanced at Pang Xuelin, and then let out a soft sigh, "Brother Pang, I haven't seen you for a day, you seem to have become different." ”

"Different? What's the difference? ”

Pang Xuelin smiled, but he was secretly surprised by Shi Qiang's sensitivity in his heart.

Last year, when I first got the sci-fi world adventure system, I was just a little budding.

Whether it is mentality or all aspects, it is still relatively immature.

This time he came back, he spent more than six years in the Martian World, more than 20 years in the Wandering Earth World, 10 years in the Rural Teacher World, and two years in the Whale Song World.

Dashi shook his head, pistled his chin and said: "It's different, it's very different, if it weren't for the fact that your face is exactly the same as before, I doubt that you have changed someone." ”

Pang Xuelin laughed and said, "By the way, Dashi, how long will I live here?" ”

Da Shi said: "It's hard to say now, we will also assess your safety status, ETO has already issued a big hunt and kill order for you, and you may not be able to move freely in a short period of time." ”

"Well, it looks like I won't be able to go to school anytime soon." Pang Xuelin nodded and said, "Then can I go to the hospital to see Zhuang Yan today?" ”

Pang Xuelin naturally did not forget the girl who was almost hit and killed in order to save herself.

Da Shi said: "Tomorrow, Zhuang Yan will be transferred to 301 Hospital today." She has woken up now, her mental state is quite good, and Li Yao has been with her. ”

"That's good."

Pang Xuelin breathed a sigh of relief.
