Although Las Vegas is only a new city developed after World War II in the United States, because of its special background, the city has been full of gangs and villains since its establishment. In addition, the United States attitude towards private arms has created this international casino with heaven and hell.

    Because of the constant murders, feuds and gangs, the Nevada government ordered a national guard to be stationed in the bomb suppression and chaos Bureau in the suburbs of Las Vegas as early as the 1950s. After sun Cheng''s previous reconnaissance of the 119 attack helicopter regiment and the 30th space wing of the air force were transferred to Las Vegas, the temporary base was the residence of the National Guard.

    After the newly captured Decepticon transformed by the [fire source] learned the information of the [fire source], sun Cheng quickly left the city and flew to the National Guard Base in the desert southwest of Las Vegas.

    Not long ago, in order to invade the seventh district, the attack conducted a round of long-range shelling here. Although he believed in his strength, sun Cheng did not completely put down his vigilance.

    The 119th attack helicopter regiment from the National Guard was just enough. According to his previous investigation, this unit was almost fully stationed in Las Vegas before being attacked because it was adjusted in the state.

    However, the 30th space wing of the US air force, who was ordered to be transferred here, is hard to say. The Air Force combat aircraft have higher requirements for the site than helicopters. During his previous investigation, he only heard that a subordinate squadron belonging to the 30th air wing was stationed in Las Vegas, and the rest were temporarily relocated to another larger military base nearby.

    "Area 51..."

    At the thought that the main force of the 30th space wing of the US air force might have been preserved, sun Cheng felt a flutter in his heart.

    The world-famous 51st District of the United States is located in Las Vegas, but it is now included in Lincolnshire. It no longer belongs to Nevada, but to the U.S. federal government.

    This is not the secret base used by the U.S. government to study aliens, as it is said. After all, the seventh district is.

    According to the intelligence seen by sun Cheng''s invasion of the national defense intranet, it was one of the test sites selected by the U.S. government in Nevada for nuclear testing.

    Later, after making adjustments, the Department of defense changed it into a new aircraft research and test site. The U.S. military not only attracted technicians from all over the country to study more advanced military weapons, but also conducted secret tests here for advanced aircraft and missiles developed by American aerospace giants such as Boeing, Lockheed Martin and Raytheon.

    Therefore, zone 51 should be one of the most heavily guarded military bases in the United States. From ground radar stations to underground sensors and then to the dense anti missile system deployed around, all of them prove the importance the U.S. military attaches to it.

    This is also a matter that sun Cheng is worried about!

    Judging from the previous conflict, the Autobots did not know when they joined hands with the Yankees. If the [ignition source] was really sent to area 51, there was a strict guard, and the Autobots helped contain Megatron, attack and vertigo. Even if several people joined forces to attack, they might not be able to please.

    Between his troubles, several smoke pillars loomed. Sun Cheng carefully distinguished them, determined that the place where the dying smoke pillar was located was the National Guard Base he was going to, quickly put all those complicated thoughts behind him and flew towards it.

    Looking down from a height of 10000 meters, the human tracks on the ground are faint, running and crawling like mole ants.

    Sun Cheng didn''t catch the electromagnetic wave emitted by the radar. He was thoughtful.

    It seems that before entering the seventh district, the effect of the raid was extraordinary. I''m afraid most of the forces originally stationed in this base were destroyed.

    He was about to lower some height, and suddenly felt that his body seemed to be swept by a wave, and then the core seemed to be locked by something.

    Sun Cheng quickly reacted. Knowing that he was locked by some mechanical life, he quickly circled in the air and guarded carefully.

    About thirty or forty seconds later, along with a distant sonic boom cloud, a significantly larger aircraft appeared in sun Cheng''s core scanning range, which was different from any aircraft on earth.

    "Megatron..."

    Sun Cheng was a little relieved, but he immediately raised his uneasiness again.

    "Now, tell me where the ignition source is?"

    Almost the next second, Megatron appeared beside him. Megatron circled around him, and his low voice was still angry.

    "Your Majesty Megatron, [the source of fire] should have been brought to this base by humans. I was entangled by a team of human fighters just now. I found it all the way after the battle!"

    He replied somewhat uneasily that human beings do not know what means have been used. Sun Cheng has been unable to capture the fluctuation of [ignition source] since just now.

    Obviously, he was worried that this answer could not satisfy Megatron.

    However, to his surprise, Megatron didn''t mention anything after hearing the answer. He dived directly and rushed down. When he was more than ten meters away from the ground, he suddenly changed back to human form and fell, and then there was a dense explosion on the ground.

    Seeing this, sun Cheng only thought he was dazzled by the [fire source], and then came to the ground together.

    Just landed, he was greeted by a burst of shells from the pavement.

    Naturally, the shell was not fired at him, but Sun Cheng landed at the wrong place.

    After rushing forward and rolling to avoid a shell that would fall near his landing site, sun Cheng followed the track of the shell and soon found several M60 series tanks hundreds of meters away.

    "National Guard..."

    The regular army of the United States has already eliminated this second-generation tank and began to equip the updated M1 series tank. This thing can be seen in China and is still in use. It must be the National Guard.

    He tried to call out the Vulcan gun and raised it to aim at an M60 tank hundreds of meters away. It was a round of strafing. The roaring energy bomb bombarded the armor of the M60 tank and sent out bursts of low and violent sounds. It lasted three rounds of shooting. He saw that the tank burst in a burst of fire.

    "This efficiency..."

    Although the power of the Vulcan gun strengthened by [kindling source] is not vulgar, sun Cheng just looked at it from a distance and raised his hand at will, and it also smashed the Megatron of an M60 tank. The new weapon that was originally very satisfied was suddenly a little out of sight.
