Starting as a Wallfacer, his defection to the Three-Body Problem shocked the world.

Three days later, PDC brought Lin Xuan the person she was looking for.

"Hello Lin Xuan, I am an academician specializing in microbiology and agricultural cultivation from the Chinese Academy of Sciences. You can call me Liu Chang."

The person in front of me was a refined man who looked to be in his thirties. He wore black-rimmed glasses and spoke in a gentle and friendly voice.

Lin Xuan stared at him for a long time, feeling that the person in front of her looked somewhat familiar.

After carefully recalling the memories of the original owner of this body, Lin Xuan suddenly realized who the person in front of her was.

Good heavens, isn't that their school's vice principal?

When Lin Xuan first entered university, she met Liu Chang once. At that time, the vice principal was standing in front of the podium, while Lin Xuan was just one of the many students in the audience.

Now, their statuses have changed dramatically. Lin Xuan has become the fifth Wallfacer, while Liu Chang has become a hired hand sent to him by the PDC.

"You're not here to ask me for the game, are you?"

Lin Xuan looked at Liu Chang with some suspicion. She had previously told PDC that they could not license the game "Star Wars: Civilization" to her alma mater, and the next second, the vice principal of her school was sent to find her. Lin Xuan did not believe that this was not intentional.

"Of course not. I've heard about the game too. Since Mr. Lin Xuan is unwilling to make a contribution to his alma mater, we can't force him to do anything, right, Mr. Lin Xuan?"

Although Liu Chang spoke in a very gentle tone, Lin Xuan always felt that he was deliberately hinting at her, asking her to get a game license for her alma mater as well.

"Principal Liu, do you live in a Bagua formation? Why are you talking so sarcastically?"

"How dare I? You are now the Fifth Wallfacer, while I am just an ordinary school principal."

Lin Xuan was speechless.

"Alright, alright, I can give you the authorization, but you have to do some work for me first."

"That's easy. PDC sent me here to assist you. Just let me know if you need any help. As long as it's within my capabilities, I will do my best."

Upon hearing this, Lin Xuan nodded slightly and then spoke.

"Principal Liu, have you ever conducted research on cloning technology?"

Upon hearing this, Liu Chang pondered for a moment.

"There are some, but as you know, before the Three-Body Crisis, research on cloning technology was always considered a scientific taboo, so humanity's progress in this area was actually very slow. Although the restrictions on these scientific research have been reduced because of the Three-Body Crisis, it is still not allowed to conduct human experiments."

"If there is no way to conduct human experiments, cloning technology can only be limited to animals and plants."

As expected of the vice president of the Chinese Academy of Sciences University, Liu Chang was able to guess Lin Xuan's general research direction as soon as she asked just one question.

Just as Liu Chang said, scientific research on agricultural products and animals was clearly not of Lin Xuan's interest; what he wanted to do was develop human cloning technology.

"That's easy. Once the Super Dream database reaches the second stage and the synchronization verification function is completed, you can conduct human experiments in the Super Dream world."

Liu Chang nodded first, then shook his head.

"Actually, it's not that complicated. In my opinion, as long as there is a way to get the PDC to pass the relevant bill, that will be fine. After all, although cloning technology is somewhat unethical, what time is it now? The PDC should be able to figure out which is more important."

Lin Xuan shook her head.

"No, Principal Liu, this experiment must be kept secret from the PDC in the early stages. Apart from you and me, uh... and Zhizi, no one else can be told. All experiments must be conducted in secret."

"This is difficult."

Liu Chang gave the result directly.

"I don't know why you hid this research from the PDC. If it's because you're afraid of ethical issues, then no matter how much you try to hide it, your purpose will be exposed the moment the experimental results come out. It would be better to just be open about it from the beginning."

"Actually, I had thought about this research before. You know, gene editing technology has always been a field that I am very interested in. They can use this technology to create newborn humans who are completely immune to HIV infection. But cloning technology is a prerequisite for gene editing technology. Without developing human cloning technology, humanity will never be able to unlock the technology of gene editing in its lifetime."

Lin Xuan naturally couldn't say that he was researching clones to prepare for building a private army in the future, so he had to use his rights as a Wallfacer to gloss over the matter.

"Go ahead and do it; it's part of the plan."

Seeing that Lin Xuan had already said so, Liu Chang had no choice but to nod.

"That's no problem, but you boasted to the whole world at the Wallfacer hearing that you would solve the food problem. Have you come up with any solutions?"

"No."

Lin Xuan answered frankly, saying that she knew nothing about agronomy and planting, and was just talking casually.

Liu Chang: ...

"What will you do if the PDC asks you for something next year?"

Lin Xuan waved her hand.

"Don't worry about that, they won't be able to wait until then."

……

Lin Xuan's game was quickly released on the market. All you needed to do was buy a gaming headset to experience an immersive gaming experience.

Because of Lin Xuan's Wallfacer identity, the price of the gaming helmet was also driven down by PDC.

For the average player, it would cost around the same as a Switch console, just a few thousand dollars.

In addition to the game itself, Lin Xuan also added a lot of knowledge about celestial bodies, the universe, and physics, disguising it as a learning machine for sale.

It's the same formula as the Subor game console back in the day.

If you say you're going to spend thousands of dollars on a game console, your parents definitely won't agree. But if you say you're going to spend thousands on a learning machine, especially one that PDC is personally promoting, your parents will definitely praise you as a good child who loves learning.

Sure enough, the machine sold like hotcakes as soon as it was released.

After all, who wouldn't want to try this brand-new gaming experience?

Inside an internet cafe in Los Angeles.

Old Cao was staring at the game character on the computer screen, constantly clicking the mouse to control the character to kill the enemies in front of him.

The network administrator standing nearby was speechless.

"Old Cao, you're cheating in a WWII-themed game. Look at your character, flying and teleporting, with unlimited bullets and a headshot lock. He can even drive a tank into the sky and crash it into someone's plane. If Li Yunlong had your cheat back then, he would have conquered Japan long ago."

Old Cao rummaged through the ashtray, picked up the cigarette butt he had just finished smoking, took two more puffs, and then spoke.

"What do you know? This is what we call a technologically advanced nation."

Network administrator: 6.

"By the way, I heard that a new gaming helmet has recently appeared on the market. It seems to be something developed in our country. Wearing that thing makes playing games so much more fun, just like being on a real battlefield."

When Lao Cao heard what the internet cafe manager said, he couldn't help but become interested.

"real or fake?"

"Why would I lie to you? I saw my boss's son buy one the other day, and I even tried it out. Seriously, the scenes in the game are so realistic, they're like a one-to-one replica of reality. When I touched the tank armor plate, I could still clearly feel the metal on my hand."

Old Cao was somewhat skeptical.

"Is it that evil?"

"Seriously, do you want to get one? I can borrow it to play with sometime."

The network administrator's eyes were full of anticipation.

"Okay, I'll go take a look."

Old Cao opened his phone and, sure enough, saw the gaming helmet as the first item on Taobao.

I glanced at the price, and it wasn't too expensive, only a few thousand yuan.

"Network administrator, lend me some money. I'll use Alipay to pay you back next month when I get my wages."

The network administrator curled his lip.

"Don't give me that nonsense. Your credit score is already terrible. Do you think Alipay would approve a loan for you?"

"I'm using my grandpa's."

Network administrator: 6!

Soon, Lao Cao placed an order for a gaming helmet.

The delivery was fast; the item arrived the next day. After connecting the power cord, Lao Cao couldn't wait to turn on the gaming headset.

"Welcome to the game Star Wars: Modern Warfare, where you will play as an officer in a campaign, personally participating in frontline combat or commanding from the rear."

"Please note that due to the extremely high level of realism used in this game, please carefully select the game's age rating."

Without saying a word, Lao Cao immediately set the age classification to the highest level.

After entering the game, you need to choose your faction. There are 8 factions to choose from.

In addition to the G7 in PDC, there is a new faction option – the Star Force.

This is a special faction with relatively advanced technology compared to the seven other countries. However, once you choose this faction, you will be besieged and killed by the combined forces of the seven countries.

Old Cao didn't know why the game designers added such a strange faction; he just assumed it was to increase the game's fun factor.

He chose the Chinese faction in his first game, but after only about ten minutes, his entire army was wiped out by the opposing American forces.

In the second game, he again chose the American camp.

This time, the defeat was even faster. In less than eight minutes, his forward command post was captured by a densely packed Chinese airdrop force.

"Grass!"

The game's difficulty far exceeded his expectations. Not only were the controls ridiculously difficult, but the game also had an extremely high degree of realism in its depiction of the battlefield environment.

For example, on one occasion, Lao Cao chose the island nation camp and wanted to launch an attack on the American troops. However, when the troops were passing a bridge that had been blown up, the bridge collapsed and all the troops were killed.

He also discovered that, regardless of which of the seven nations he chose, the game seemed to always end in a final battle against that particular Star faction.

The key issue is the vast technological gap between us. We're still using kinetic weapons, while the Star Forces are already using laser guns.

On one occasion, Lao Cao even saw someone in the Star Force piloting a Gundam. Those EMP electromagnetic oscillation shells, thicker than a person, could paralyze an entire tank unit with a single shot.
