"Human flesh and blood directly determine that humans are no match for robots in this battle. If we do not find a way to turn the tide, humanity will face the crisis of extinction."

"One of the most outstanding doctors at the time, Dr. X, developed a new type of virus, which he named the X virus."

"The news that the X virus can enhance human physical fitness and give humans super healing abilities has excited everyone. Relying on the X virus, humans have created a group of bio-warriors."

"The situation of the war began to change, but just when humanity was about to win, an accident occurred."

"A large number of bio-soldiers injected with the X virus turned into terrifying monsters because they could not withstand the mutation of the virus. They were ferocious and bloodthirsty, and instinctively craved to eat people."

"What's even more despairing is that once bitten by these terrifying monsters, you become like them. The virus spreads like a plague, and most of humanity turns into zombies."

"Faced with this disaster, humanity made a grave mistake—to deploy nuclear weapons on a large scale to eliminate robots and zombies."

"The impact and harm caused by nuclear radiation far exceed human imagination. Earth's resources are polluted, the environment has become extremely harsh, and nuclear radiation has brought about terrible mutations. It is cruel and dark, and the real apocalypse has arrived."

"Of course, this is only the surface reason," said Number 83. The green text on the projection screen in front of Xia Linyin refreshed, and new content appeared.

"The real cause of the apocalypse: Before the robot strike day, Dr. X put forward two points at a Federal Council meeting. First, robots need human rights and should stand on an equal footing with humans. Second, because humans are heavily dependent on robots, having everything done for them, their bodily functions have begun to degenerate, and in a few hundred years, humanity will perish."

"Everyone considers Dr. X's views to be nonsense. First, robots are programmed to obey human instructions when they are manufactured. Robots will never betray humans; they are machines, not humans, so they do not need human rights. Second, with today's advanced medical technology, human lifespans are increasing thanks to drugs, so the idea of ​​extinction is completely unfounded and alarmist."

"Although his views and requests were rejected by the committee, Dr. X did not give up. His ideal world is one where robots and humans coexist on an equal footing, rather than one side exploiting the other to the fullest extent. If things continue like this, humans will become lazier and their physical functions will deteriorate, while robots may rebel under long-term oppression. Such rebellion only needs a fuse."

"Humans and robots should work together to develop Earth's civilization and explore outer space."

"After the robot strike, feeling that his suspicions had been confirmed, Dr. X devised a plan to create the most perfect robot and named him 'Original Sin'."

"Dr. X concealed the fact that the X virus could turn people into zombies. In his view, the population had exceeded the Earth's capacity, and evolution is about destruction and creation. He planned to use the X virus to eliminate a group of people, leaving behind only humans who had adapted to the X virus and were strong in all aspects."

"As Dr. X had predicted, Original Sin became the leader of the robots. The next plan was for the robots and humans to reconcile, work together to eliminate the zombies, and rebuild their homes."

"But Original Sin did not follow Dr. X's instructions. The war continued, and what happened afterward was beyond Dr. X's control. Nuclear weapons exploded, plants and animals mutated, and the earth became a hell."

"When Dr. X created Original Sin, he entered the instruction 'Robots and humans should coexist equally and develop Earth's civilization together.' However, Original Sin was infected with a virus, causing a program error, which resulted in Original Sin not following Dr. X's instructions."

"Player's mission: To heal the original sin of robots and rebuild human civilization."

After reading the last sentence, Xia Linyin asked, "Where do I need to find the original sin?"

A map appeared on the screen, with a red line winding across it.

"The original sin lies in the central base of the robots, and I have already drawn the optimal route."

As No. 83 was introduced, the starting and ending points of the red line flashed briefly.

How to fix it?

"Find the control panel at the central base. Leave the rest to me. I will eliminate the virus in the original sin and repair it. Once the mission is complete, the task will be finished."

"And what about the next sentence? Rebuilding human civilization."

"Once the original sin is repaired, he will naturally carry out Dr. X's previous instructions to help humanity rebuild civilization."

The sound of rolling stones rang out, and Li Luo, who had gone out to throw away filth, returned to the cave.

He walked to the bedside, took Xia Linyin's slender hand in his large palm, looked at Xia Linyin's weak face, and said with remorse, "Sister, I'm sorry."

"Sister..." Xia Linyin rolled the word around in his mouth, then looked at Li Luo and asked, "Do you know who I am?"

Li Luo placed his hand on Xia Linyin's forehead to check her temperature. "Are you delirious from hunger? Of course I know. You are my sister, and I am your brother."

"Brother?" Xia Linyin frowned. "Are you Li Luo?"

"Sister, what's wrong with you?" Li Luo looked at Xia Linyin with a serious expression.

“He is Li Luo, and you are Li Yin. He is your older brother in this game,” said No. 83.

Xia Linyin lowered her eyes, puzzled by Li Luo's attitude towards her. He seemed to have no recollection of her at all, just like a normal NPC. Had he not yet recovered from the aftereffects of his forced intervention in the game?

Or did something happen after the last game?

Xiao Li once said that the game had erased his memories several times, but he had regained them each time.

I wonder if taking out the crescent blade will remind Li Luo of something, just like when she took out the headshot dice cup during the clown game, Li Luo remembered it.

"Brother, do you love me?" Xia Linyin suddenly asked.

Li Luo paused for a moment, then ruffled Xia Linyin's messy short hair. "Of course your brother loves you."

"No, I don't mean sibling love, I mean the kind of love between a man and a woman. Do you love me?"

The girl's bright black eyes were fixed on him intently. Li Luo got up and walked outside, saying, "Are you really that hungry? I'll go find you something to eat."

She hurriedly limped two steps when Li Luo's body suddenly swayed, and then she fell to the ground motionless.

Xia Linyin's eyes widened, "Li Luo!!"
