With the big killer of supersonic flight, Luffy's upgrade journey has been significantly improved. If you want to talk about the top three countries in terms of population, Lu Feiyang first thinks of the Celestial Empire, followed by the Three Kingdoms, and finally the American Imperialism.

As a member of the Celestial Empire, even in the world of TV dramas, Lu Feiyang can't attack his compatriots for the time being. Even they produce paraffin rice, gutter oil, formalin vegetables, rubber eggs, beef paste brand beef, hydrogenated vegetable oil, etc.

In fact, relatively speaking, killing zombies in the United States is not very cost-effective, the land area of the United States is not much less than that of the Celestial Empire, but the total population of the United States is only a fraction of the total population of the Celestial Empire. The Three Kingdoms, a land of less than 3.3 million square kilometers, has a population of more than 1.25 billion.

It's just that the TV series The Walking Dead was filmed in the United States, so the location where Luffy Yang crossed was the United States, and if he wanted to go elsewhere, he had to work hard. If it was at Luffy's previous speed, and he wanted to change the map, of course, it would be to fly so much that he wanted to vomit. But now, it only takes him more than ten hours to fly to the other side of the world without stopping.

"But when you come to the US imperialists, how can you not go to New York? Even other populous cities like Los Angeles, Chicago, Houston, and Philadelphia aren't planning to make a trip? There's nothing to see in Las Vegas right now, and there's always value in going elsewhere," Luffy thought to himself, and by the way, he also wanted to see if the number of "corpses" left in these cities could make him a few levels.

And it just so happens that Philadelphia and New York are really not too far from where Luffy Yang is now, at his speed, that is, more than half an hour. Of course, there are so many cities along the way, and there must be a lot of zombies, if Luffy Yang hadn't seen the real-time map in Charlotte City, he would definitely have to fly over slowly and clean it up by the way.

Now that he has a definite goal, although Luffy Yang saw several waves of tens of thousands, hundreds of thousands of zombies in the sky, he didn't have the experience to go down to harvest. More than thirty minutes later, Luffy reached the skies above Philadelphia. Look at the long snake-like zombies slowly migrating towards the ocean on both sides of the winding Delaware River. Luffy didn't stop, and after lowering the altitude, he flew out of the Moon Golden Wheel and rushed in the direction where the zombies came.

It's just that the Delaware River is about 90 kilometers long from the location where Luffy Yang landed to the source, and it is impossible for Luffy to fly out of supersonic speed at this altitude, so although Luffy gave up going against the current halfway when the zombies were becoming scarcer, he also flew for an hour to clean up a zombie on the shore.

Looking at the gradually scarce zombies in front, Luffy said: "It seems that there are no zombies in front of you, they have all gone to the back, forget it, I don't bother with these zombies, I turned my head and went to another shore to clean up." ”

After thinking about it, Lu Feiyang didn't care about the zombies that were still slowly swaying in front of him, and as soon as his mind moved, he flew towards the opposite bank.

With the experience of money twice, Luffy Yang also killed the number of hands, and this time he actually killed the zombies here in more than ten minutes faster than the speed on the other side.

After cleaning up the zombies on both sides of the river, Luffy Yang retracted the Moon Golden Wheel and raised the height to see from the air. Seeing that there were no more zombies in Philadelphia, Lu Feiyang flew towards the city center. The main purpose of Luffy's landing this time was not zombies, but the vaults of major banks in Philadelphia.

"As a reward for your efforts to clean up the zombies, I will collect some ownerless property, you should have no opinion, right?" Luffy thought shamelessly in his heart.

Seeing that the time was already in the afternoon, Luffy Yang thought about it and didn't continue to fly towards New York. He thought: "There are still many places in Philadelphia that have not been collected, if you go to New York now, you can't clean up the zombies in New York today, but it will waste the resources of Philadelphia, so it's better to take advantage of the time there is still today to sweep Philadelphia well, and tomorrow there will be time to go to New York." ”

After making up his mind, Luffy Yang did not delay, and his mind invaded the ground with a trace of his mind, looking for those belongings that might have been missed.

Luffy's busy night in Philadelphia was still in the underground conference room, and the screen showed Luffy Yang strangling zombies outside the walls of the Camp Lejeune Marine Corps base. It's just that from the perspective of the picture, this shooting is not a satellite, but a monitor in the base.

"It seems that this man has evolved again!" The tall old man said, and after he finished speaking, he said to the person who was about to grab Luffy Yang to study: "Matt, how is his blood research?" ”

When Matt heard this, he showed a strange expression, and finally said, "Harley, after hundreds of studies, the samples we collected contain all the elements in human blood, and the proportions are all the same. ”

Hearing Matt's words, the tall old general knew that there was something to follow, so he didn't speak, but kept staring at Matt. Matt looked frightened, as if in a dream, "But our hundreds of studies have never unearthed anything valuable from the samples." ”

William, who was sitting in the corner, repeated strangely, "Didn't find anything of value?" What do you mean? ”

In addition to being a scientist, Matt is also an officer, albeit only a technical one. In the time of these few words, Matt came back to his senses and said, "In other words, there is nothing else in the samples we have collected. Except for the elements that make up the blood, there is nothing related to human beings, cells, genes, dyeants, none of this! ”

The whole conference room fell silent.

After a long time, Harley said heavily, "Matt, what do you mean by that?" ”

Matt seemed to have been thinking about Harley's question for a long time, and after hearing Harley's words, he said without hesitation: "I think he may not be a human, but a man-made object!" ”

"Man-made objects?" Another voice said, "Do you mean robots?" ”

Matthew nodded, "That's right, I think it's very likely." ”

"But who could build such a robot?" William pointed to Luffy, who was flying in the air on the screen and controlling the Moon Golden Wheel to slaughter zombies outside the Marine Corps base in Camp Lejeune, and said: "Can fly at supersonic speed, can control metal, even we can't, I don't believe there is more advanced technology than us on Earth!" ”

"Is it possible that alien creatures?" After thinking about it, Harrow asked Matt, "Don't forget how the virus broke out!" ”

Speaking of this, everyone shuddered, and even the smile on William's face, who had been smiling, disappeared. He said, "Harley, you mean ......?" ”

"That's right, immediately transfer manpower, as long as you locate him again, I will catch him!" A cold tone like ice slag came out of the mouth of Harley's tall old man.

Poor Luffy didn't know that someone had already seen him as the culprit of the virus and was thinking about arresting and dissecting him.
