The Hoover Dam was the brainchild of the 31st President of the United States, Herbert Brown. C. Hoover ordered the construction. It has played a huge role in flood control, irrigation, urban and industrial water supply, hydropower generation, shipping, etc. Of course, this is information on the surface, but secretly it is a secret base. For research and protection, a treasure from the universe.

Throughout Cybertron's long history, the existence of the Tinder Source has been the treasure of the planet, a body of energy with a huge amount of energy. But during Cybertron's long civil war, the Tinder Source was lost, and it crashed down the Earth's Colorado River, where it was discovered by seven explorers in 1913. President Hoover built the Hoover Dam around the source of the fire in order to protect the source of the fire and the discovery of NBE-1 (Megatron) in the Arctic. For protection and research of the source of fire!

And now, with the arrival of the powerful intelligent mechanical life race in the universe, they have gradually found the location of the source of the fire, and are approaching the location of the source of the fire - the Hoover Dam!

"You've all been in direct contact with NBE."

“NBE？”

"Non-biological aliens." And he said, "Remember, what you see next is highly classified!" ”

"Oh my God, what is this!"

Presented to the public was a giant robot, frozen in ice, and the refrigeration equipment was running non-stop, keeping him frozen.

"We believe that the Earth's gravity disturbed his navigation system as he flew over the North Pole. He fell into the ice, probably thousands of years ago. We brought him here in 1934 and we called him NBE-1. ”

Sam, who came with him, said, "I'm sorry sir, I don't want to correct you, but I'm going to say it's not NBE-1, it's Megatron, the leader of the Decepticons!" ”

"He has been frozen since 1935, and your great-great-grandfather made the greatest discovery in human history. In fact, what you see... It is the source of modernization, microchips, lasers, space flight, automobiles... It's all learned from reverse-engineering him, and NBE-1 is what we call it. He walked beside Sam, accentuating the emphasis on naming rights.

……

"Then why did he come to Earth?"

"Because of the source of the fire!" Sam preached.

The people around him were puzzled, "The source of the fire?" ”

"It's a cube-like thing, NBE-1 aka Mr. Megatron, they call him as such, he is the messenger of death, who wants to use the energy body to transform human technology and then rule the universe, that's what they do." Sam popularized Megatron's origins and the source of the spark, "You know where that thing is, do you?" ”

"Follow me!" The person in charge said, "What you will see is the ultimate treasure!" The group followed him to another room, and they saw a huge cube half-suspended in the air. Around the cube are artificially built metal planks and engineering equipment, where many engineers and researchers are studying this huge metal cube.

"Carbon-14 dating estimates that the energy body came to Earth in 10,000 BC, and the Seven Elders only discovered it in 1913, and they knew that it was an extraterrestrial object because... The branding on its surface is very similar to that on the surface of NBE-1, so President Hoover built a dam to hide it in it, and the cement is four football fields thick, so that no one or any alien race outside can detect the energy it emittes. ”

At the moment when everyone was shocked by the source of the fire, as a small spy robot, he also saw the source of the fire hidden by the heavy dam, so he passed on the information of the discovery of the source of the fire.

Subsequently, this set of information was instantly learned by the members of the Decepticons disguised on the earth, the F-22 Raptor fighter disguised by the Red Spider, the police car disguised as the barricade, and the noisy disguised tank... At this moment, they rushed to the location of the source of the fire as fast as they could.

At this time, there was also an evil figure in the outside world who noticed the police car disguised as a barricade, that unusual scene! He quietly turned into a black fog and hid under the police car disguised as a roadblock.

……

"You say the dam hides its energy, what energy?"

"Good question!"

Then, everyone once again saw the power of the Tinder, a small mobile phone received the power of the Tinder, and became a murderous small robot.

Outside the dam, a convoy of Decepticon members is also coming quickly. However, their speed was never as fast as that of the Red Spider, disguised as an F-22 fighter. He was the first to reach Hoover Dam and then attacked! Attacking the power supply, Confusion also takes the opportunity to enter the control room, turning off the refrigeration device that freezes Megatron and raising its surface temperature, causing the ice to melt and wake Megatron up.

At the moment of the Decepticon operation, the Autobots led by Optimus Prime also hurried over.

Subsequently, the released Bumblebee turned off the huge Tinder Source into a small cube, and led the Tinder Source to evacuate as the power supply system failed and Megatron was about to wake up.

And the awakened Megatron then began to wreak havoc, cleanly dismantling everything that stood in his way, and then transformed into a fighter jet and flew to the outside world. The Bumblebee with the source of the fire also quickly joined up with the Autobots' team, but the Decepticons members who followed closely behind also followed behind the Autobots. The attack was the first to move, he changed his form, he was huge, and the human car was a toy in his eyes, and when he raised his hand, he easily tore apart the cars driving on the highway. When the attack came, Optimus Prime quickly changed his posture to block the attack. However, the black fog hidden under the barricade also quickly floated out, and in the process of flying, it turned into a blood-colored mist, attracting everyone's attention.

The blood mist flew extremely fast, leaving the Decepticons and Autobots behind and approaching Bumblebee quickly.

"The purpose of the other party is also the source of the fire!" Although Optimus Prime didn't understand what this blood mist was, it was not difficult to guess his purpose as he watched this blood mist quickly approach Bumblebee's movements.

At his warning, the Autobots blasted their cannons into the air of a mist of blood, but they didn't touch any entity at all. The cannon fire went straight through the blood mist and detonated in the air.

The blood mist didn't pay any attention to the cannon fire, and the moment it approached the bumblebee, it dispersed violently, and fiercely blocked in front of the bumblebee. And the bumblebee hit it straight away. However, it was as if he had entered the liquid glue and could not move! Sam, who was hiding in the car, screamed, completely unaware of what was going on.

Then, under the gaze of a group of alien lifeforms, the blood mist turned into an evil figure. The long black hair was neatly combed, dressed as a medieval aristocracy, and the mouth was slightly open and closed, faintly revealing sharp fangs.

"Give me the spark source, little one!"
