Level C, Zone 1.

The outer line of defense had completely collapsed, and the soldiers were compressed into a small space in the city. Relying on the terrain, they are constantly retreating and building defensive positions to deal with the infected.

Gunshots echoed through the central city of District 1.

The General Headquarters building has been destroyed by the "Black Body", and the General Headquarters has been moved to the ground below the building. Layton looked at the map of the operational situation in front of the command room. He picked up the gun that hung aside.

"How many people are left?"

The guards beside him saluted. "The exact number is not yet known, and contact with each team has been lost, but judging from what the command has observed outward, we have not been compressed into a narrow area of five kilometers with the headquarters as the center."

Layton sighed. "Four months, only four months."

His hands clenched slowly, and his fists slammed hard against the table. "Layer C, only four months."

The guards hurriedly stepped forward and grabbed Leiden.

In the smoke of gunpowder in the distance, the soldiers fought hard against the enemy. Flesh and blood collided in the flames.

With guns in their hands, daggers at their waists, fists, and feet, soldiers fought with an enemy that was dozens or even hundreds of times their size.

The army of the black-pressed infected poured in like a tidal wave, constantly pouring towards the center of the city. One by one, the heroic bodies fell, and the infected trampled over their corpses, blood spreading across the ground.

Layton climbed one of the upper floors next to the headquarters, and he looked at the city as it was. Once upon a time, this place was a paradise for human beings, and now, it has become a tomb for countless warriors who fought to the death for mankind.

He suddenly remembered a war that happened in Sparta thousands of years ago, three hundred brave Spartan soldiers, defending a city, blocking the attack of tens of thousands of Persian troops, defending their country and people, and defending the territory behind them.

Their souls will forever haunt that land, for it has become their permanent home.

From the time the human government discovered the existence of danger, to the present, the all-out war between the two civilizations has only passed for a short period of nearly two years.

In the distance, a soldier smashed the butt of his rifle at the infected in front of him, his brains splashed on the wall, and the soldier's chest was pierced by a pale and thin hand, and blood dripped to the ground in front of him. Countless infected stood behind the soldiers, their eyes were rich gray, and there seemed to be a smile on the corners of their mouths, as if they were mocking the useless resistance of the weak.

In the distance, the soldiers were still desperately resisting, facing a huge number of enemies, facing a powerful enemy, not a single one escaped, not only the soldiers, but also the unarmed people, who fought the infected with their mouths, hands, and feet.

The army slowly advanced and reached the command post. The infected stopped in agreement, and a huge image in the sky slowly appeared.

Shirakawa Xiao sat on the throne and looked at the high-ranking general of the human race in front of him with a smile.

"General Leiton, I have long admired my name." There was a hint of banter in his tone.

Leiden looked at Shirakawa Xiao, and he didn't speak.

Shirakawa Xiao's fingers lightly tapped around Leiden, and he slowly drew a small circle.

"See? This is the world you are in now," he said, "and you will soon be defeated." ”

"We're not going to wipe out humanity." Shirakawa Xiao uttered something that made Layton unpredictable.

"As long as you surrender, I will give you a higher status among the surviving humans, and even, I can put those people in your hands."

Leiden suddenly aimed the gun in his hand at Shirakawa Xiao in the air, and he pulled the trigger without hesitation.

The bullet whizzed through the air in an arc, through the ethereal impact.

"I don't share the sky." Layton gave only four words of answer. He almost roared in an angry voice.

The soldiers held their weapons aloft. "Don't share the sky!"

A strong voice erupted from the crowd.

Bai Chuanxiao shook his head, his eyes showed deep pity, looking at the helpless people in front of him who had been cut off from the back road. He waved his hand to the infected behind him.

The black-pressed figure slowly pounced.

Bursts of white smoke came out of the muzzle of Layton's hand, and when he ran out of bullets, he pulled out the long knife at his waist.

This was personally delivered to him by Hua Chengyu when he was awarded the rank of general, and he never thought that there would be such a day when he would use this weapon like this. He rushed into the darkness. Silver light flying.

He didn't know how much time had passed, but this was his first swing. There was no strength in his body anymore, he was half-kneeling on the ground, the tip of the knife pierced deep into the ground, he gasped for breath, and the military uniform on his body had already been dyed blood red.

He looked at the infected in front of him, their eyes so gray that it was hard to imagine that they had been one of the normal humans just a few months ago, they were slowly approaching, their movements mechanical and stiff.

Layton pulled out his pistol, his hand running out of strength, and he slowly raised the muzzle.

He struggled to his feet, and all around him, the soldiers had all fallen, clutching their weapons to death, their bodies trampled under the feet of the infected. In the distance, above the wreckage of the city, black smoke and dust slowly rose upward.

Now, he's the C-layer, the only living human.

Layton unloaded all the extra bullets, and the bullets fell to the ground with a crisp sound. He turned on the communicator and connected Hua Chengyu.

Then pull the bolt and slowly pull the trigger.

The sound resounded throughout the world. The tall figure slowly fell.

The dim light was shrouded in smoke and dust, and the sky was completely gray.

Floor A, Countermeasures Bureau.

People bowed their heads in silence. Hua Chengyu slowly walked out of the hall of the countermeasures bureau.

The guard hurriedly broke into the hall and crashed into Hua Chengyu, who was shocked back a few steps and almost didn't stand firm. The guard raised his head, and he hurriedly apologized to Hua Chengyu.

Hua Chengyu waved his hand at him. "What's wrong?"

Only then did the guard come to his senses. "In power, the outer jurisdictions of District 1 have been attacked by 'black bodies'."

The red light of the communicator flickered continuously, and all floors kept sending reports on the battle situation.

Almost at the same time, after the fall of the C layer, the army of "black bodies" scattered across the layers launched a full-scale attack at the same time.

Zuo Si immediately contacted the troops on the outer defense line of District 1 and strictly ordered him to defend it, and at the same time mobilized all the reserves, ready to go up to the defense line at any time.

Hua Chengyu looked at Zuo Si. "How's it going over there?"

Zuo Si was stunned for a moment, he quickly understood what Hua Chengyu meant, and he shook his head. "There has been no news yet, and the specific situation is not clear at the moment."

Qi Yue walked out of the hall. "In power, the members of the 'Tracing Stream' operation were found to have returned."

"What?" Everyone looked at this side, the members of the 1,000-member detachment that carried out the "Tracing the Stream" plan had not been heard from for nearly five months, and the government had almost acquiesced in the death of all their members.

"How many?" Hua Chengyu asked.

"There are only four members of the Nan Qiyun group left, and according to the situation they reflected, the rest of the personnel were all killed."

"Bring them here." Hua Chengyu said and walked out of the hall of the countermeasures bureau.

When he returned to this world again, although the war had raged, Nan Qiyun still felt a little cordial, he still belonged here after all. They arrived in Area 6, which happened to be inside the defensive line that had previously confronted the "Black Body" army, and they quickly connected with the government officials, who did not dare to slack off and quickly reported the situation to Qi Yue, the supreme commander of the "Tracing the River" operation, and then sent them back to the government headquarters building.

After half a year, they returned here again, and there were many unfamiliar faces in the flow of people coming and going, Nan Qiyun didn't ask the reason, on the way he knew the general situation, and he knew the general reason in his heart.

In the conference room on the 36th floor of the headquarters building, they met with the ruling Hua Chengyu. A few months have passed, and the original impression of the supreme ruler of the human government has changed greatly.

Nan Qiyun directly reported to Hua Chengyu all the events and intelligence information that his group had experienced from the beginning of the operation to the moment before returning to this era.

The situation known by the operation is very different from what has been known for more than 300 years, and the arguments of the edifice threat theory released by the society have become true, and those people's guesses are correct, and the trend of human history has been controlled in the direction of its own disadvantage for more than 300 years since 2102, but human beings think that they have created a paradise.

"Anything else?" Hua Chengyu asked.

Nan Qiyun knew what he meant by asking. He shook his head.

"Oh." Hua Chengyu nodded slightly, and he turned to look out the window.

Now, for the whole of humanity, the meaning of knowing the truth is not very important, if there is no way to save it, then no matter how much you know, you can't change the outcome. The "tracing the stream" operation is actually equivalent to a failed outcome.

Nan Qiyun looked at Hua Chengyu's back, he hesitated for a long time, but he didn't know what to say, in this situation. On his way here, he had learned of the final all-out assault of the Infected.

He suddenly felt dizzy in his brain, his vision slowly blurred, he couldn't see the scene in front of him clearly, something seemed to be in his body slowly rushing up to his head, and his consciousness gradually felt tired.

Chu Han saw Nan Qiyun's body slowly falling backwards, and he hurriedly stretched out his hand to help Nan Qiyun. "What's wrong?"

The words stopped suddenly, and he saw that in Nan Qiyun's pupils, a small patch of gray was slowly spreading outward. Nan Qiyun's palm suddenly slapped towards Chu Han, and the huge force shook Chu Han back a few meters directly, and his body smashed against the wall behind him.

He stood up, looked at Hua Chengyu, then pulled out his pistol from his waist and slowly raised it.

Han first rushed over, he saw Nan Qiyun's muzzle slowly aimed at Hua Chengyu, the crisp sound of the bolt pulling sounded in his ears, and his fingers slowly pulled the trigger.
