The convoy stopped in front of a fort in the center of the city, which had obviously been fortified by military means, but was absolutely inconspicuous, and after a series of extremely tedious inspections and various identity checks, a high-ranking official from the American side came out to receive Liu Yun and his party.

Because the Chinese are so strange that even any information is extremely correct, the US side still maintains 100 percent vigilance.

There were several US officials who received General Liu Yun, some of whom were extremely familiar with the situation in China, some of whom were extremely familiar with Liu Yun's own situation, and even Liu Yun's old friends.

Liu Yun immediately made a request to meet with a higher-level US commander.

As Liu Yun, it is not too much to make such a request.

After a slight hesitation, the US side gave an affirmative answer.

But only Liu Yun and the four attendants around him could enter the depths of the fortress, and the others had to stand by in place.

Vigilance to this extent, it can be seen that the former world hegemon has now become a frightened bird, frightened by insects, and does not dare to be sloppy in the slightest.

Like China's base cities, the United States is the core command base, which is still underground.

After taking the elevator and going down for at least 600 meters, I stopped and came to a huge and modern base, which felt like an isolated city, with streets and buildings, full of buildings and passages in the style of the futuristic world, and airport-like ground conveyor tracks, extending in all directions.

Liu Yun and others had expected this scene for a long time, similar to China's underground cities, but in terms of technology, it was obviously slightly more advanced than China, which may have something to do with the fact that it took Americans to build this underground base for a longer time, and such an underground city should have been built before the apocalyptic disaster.

Through the conveyor track, Liu Yun and the five were sent to an unknown place.

Enter a large, transparent room.

As soon as Liu Yun and the five of them entered the room, the electronic tempered glass suddenly closed without warning, and they were completely isolated, like guinea pigs locked in a laboratory.

"What are you doing here?" Liu Yun was taken aback, and the attendant next to him asked in English.

If it weren't for the fact that Sun Fei, who was invisible to the Americans, by his side, several people would have begun to worry a little about what tricks the Americans were going to play.

"I'm sorry, General Liu, you also know that according to our latest research results, bugs have an unpredictable ability in terms of spiritual power, and there have been some high-level bugs in the city before, using mental power to control the human body, and then infiltrating the command center, so we must be sure that we are now looking at real Chinese friends, not some walking dead controlled by bugs!"

The American officer, who was familiar with Liu Yun, said apologetically.

Sun Fei suddenly felt strange in his heart.

Looks at this, Americans have experienced a similar thing before, and they have actually found a way to distinguish or break this kind of mind control?

That's really intentional.

What an unexpected surprise.

While speaking, I saw wisps of white mist, through some invisible passages on the ground, injected into the white glass room, and in an instant, the fog completely enveloped Liu Yun and the others, and the air was filled with a strange fragrance.

"General Liu, don't worry, this is a gas that only works on the spiritual power of the insects, and it will not cause any impact on the human body, you only need to stay in this gas for ten minutes to erase all the spiritual power control of the insects. ”

The American officer explained with a smile on his face outside.

Liu Yun didn't have any special expression, he had seen all the scenes, although with his status, it was inevitable that he would be a little angry when he was tossed by the Americans like this, but considering that Sun Fei seemed to have a plan, the old general was not shocked by the honor and disgrace, and kept his composure.

Sun Fei reached out and caught a cloud of white gas.

What kind of substance this is is difficult to justify, but one thing can be determined, this gas does have a certain corrosive effect on spiritual power, especially on the fluctuations of spiritual power in the unique spectrum of the Zerg.

"The Americans actually came up with this kind of funny thing, not bad, haha......"

Sun Fei took some gas samples and waited for the Chinese government laboratory and the [Madman Laboratory] to replicate and study, this was the first time he had encountered that technology had the power of restraint against things within the magic superpower.

Ten minutes passed.

Liu Yun and others were released from the tempered glass laboratory.

"I'm really sorry, everything can be confirmed now, old friends are welcome to come here as guests......" The American officer smiled at the previous time.

"Hmph!" Old General Liu, Tiger Old Yu Wei, snorted angrily.

The Yankees smiled and apologized again and again, and then took Liu Yun and the others to continue walking towards the deeper part of the underground city, talking and laughing along the way, and asked intentionally or unintentionally: "Old friend, don't be angry, after all, the whole world is now under attack from insects, you suddenly came, we can't help but doubt, by the way, it's really incredible, how did you cross such a long distance......"

Liu Yun paused slightly, and then smiled mysteriously: "This is a secret, when I meet your real commander, I will also talk to you about this matter, because we are also very interested in the American defense shield system and superpower weapons." ”

While talking, I took the elevator again, and I don't know how many meters I descended, and came to a more heavily guarded building.

Some researchers in white coats were busy in the building, and then Liu Yun met Vice President Duranlin, the Supreme Commander of the United States.

U.S. President Obara was tragically killed on the first day of the Zerg outbreak, and now everything in the United States is in the hands of this powerful vice president.

Sun Fei's attention was mostly drawn to the various laboratory scenes of architectural physics.

The Americans caught a lot of live bugs, conducted live experiments, tried to find the weaknesses of these monsters, and in addition to the spider monsters and bug monsters, they also caught a lot of high-level bugs, these progress, obviously much stronger than the Chinese military.

Soon, Sun Fei discovered something that shocked him extremely much.
