Four cars drove on the highway at high speed. After a while, the sound of a communicator came from Optimus Prime’s broadcast. It was the voice of jazz.

"Optimus Prime, Bumblebee and Sam were captured by humans. Bumblebee was afraid of hurting humans, so he did not resist. Shall we save him first?" Jazz's voice seemed a little anxious.

"But saving him will hurt humans." Optimus Prime's heavy voice came from the radio.

"What about Bumblebee? We can't just make him a human experiment." Sir said.

"However, if we don't complete the task, he will die in vain. Bumblebee is a brave warrior, and he wants us to do it." Optimus Prime's voice sounded on the radio.

"Why are we saving humans? They are primitive and violent races." Tinhide's voice appeared on the radio.

"Aren't we? They are a young race, and there are still many things to learn. However, I have also seen their kindness. Freedom is the right of all living entities. There is only one way to end this war, which is to use the Rubik's Cube. Destroy." Optimus Prime's voice sounded from the broadcast, and the leadership qualities in his words were unobstructed, causing Song Qingge to nodded uncontrollably. "If the mission fails, I will put the fire into my chest."

"That is a suicide, the Rubik's Cube is full of primitive energy, and you will die with it!" The voice of the ambulance sounded.

"For the peace of this planet, sacrifice is inevitable. We cannot let mankind be extinct because of our mistakes. I am honored to fight alongside you." Optimus Prime said in a solemn voice.

"Hehe, in fact, you don't have to worry too much." Song Qingge said slowly at this time.

"Does Commander Song Qingge have other opinions?" Jazz's voice sounded eagerly.

"There are humans on our planet. Through my observations during this time, the culture of this world is similar to ours. Therefore, I can conclude that although the bumblebee will suffer some harm, it will not damage the body, and, We will see him soon." Song Qingge smiled.

"Why?" Ironhide's voice sounded.

Song Qingge said, "Why do you think the Rubik's Cube is located under a dam?"

"You mean they hid the Rubik's Cube on purpose?" Optimus Prime said.

"Yes, human society is more than just one or two factions. They have nations, countries, governments, and disputes. Therefore, they will hide the unknown and unexplorable things to avoid other forces' discovery. "Song Qingge said, "Furthermore, you have also taken human science and technology highly. If you get something far beyond your knowledge, will you dismember it? Or keep it intact for future research? "

"You mean, like the Rubik's Cube, Bumblebee will be hidden by humans to ensure future research?" Optimus Prime's voice sounded.

"Yes, what's more, the human sector has some classification properties. If they find that the essence of the Hornet is the same as the Rubik's Cube under the Hoover Dam, what will they do?" Song Qingge asked rhetorically.

"It will be transported to the Rubik's Cube, sorted and studied." The Jazz said suddenly.

Song Qingge nodded, "Yes, that's it. There is no conflict between going to the Rubik's Cube and saving the Hornet. That's why I said that the Hornet may get some harm, but it won't hurt. Ontology, and we will meet soon."

"Commander Song Qingge, it's really our luck to have an ally like you. We all lost a bit just now. Fortunately, you wake up in time." Optimus Prime's voice sounded.

"It's okay, but I understand a little bit more about the human world." Song Qingge said with a smile, "As for the energy cube, you don't actually have to be pessimistic. You used to be the Autobots facing the Decepticons alone, but now we have us. Joining, we are not necessarily weaker than them in terms of numbers and firepower."

"That said, with the mutual assistance of both of us, I believe this mission will definitely be successfully completed." Optimus Prime said in a deep voice.

"Autobot, speed up!"

"Yes!"

As everyone let go of their worries about the Hornet, they began to accelerate toward the Hoover Dam in Nevada.

On the other side, Sam and Michaela and his parents were all captured, while he and Michaela were carried by helicopter and flew towards the Hoover Dam.

Because of Song Qingge's assistance, Autobots such as Optimus Prime and other Autobots moved far faster than in the plot to reach the vicinity of the Hoover Dam.

Song Qingge glanced at the heavily armed personnel on the dam from a distance, and said to Optimus Prime, who was still like a truck, "It is certain that the Hornet and Rubik's Cube are here, and their defensive strength has been strengthened."

At this time, a helicopter landed on the dam, and several people walked down from it, among them Sam and Michaela.

With the sound of metal rubbing of "Kaka Kaka", the four Autobots present all completed their transformations.

"It's Sam and Michaela. It seems that, as you said, Bumblebee and Rubik's Cube are in this. But the most important thing now is how do we get in here?" Optimus Prime said.

"Otherwise, just break in?" Ironhide lit up the cannon in his hand.

"No, Ironhide, we can't hurt humans." Optimus Prime stopped Ironhide's crazy thoughts.

"Then how do we get in? There must be no way to get in like this." Tinhide said with an angrily retracting the barrel.

At this time, Song Qingge touched his nose, "Otherwise, let's go. My ship mother and I are both humans, and it’s easy to talk to them. Also, you need to stay here to prevent the Decepticons from suddenly Attack."

Optimus Prime nodded, "You're right, you won't cause too much turmoil when you go, but it's too obvious if we go. Autobots, spread out, turn on the detection system to prevent the Decepticons from attacking! "

"Yes!" After the Jazz and the others answered, they ran to the side, looking for a good hidden location. Song Qingge followed his ship mother and walked towards the dam.

Because of the short distance, Song Qingge walked to the side of the dam within a short while. Normally, the entrance is open to tourists, but today, there are soldiers with live ammunition standing on both sides of the entrance.

Seeing a few people from Song Qingge approaching, a soldier immediately said: "Today the dam is not open to visit, please return the same way."

Song Qingge smiled and said, "Excuse me, please inform the engineer Recchi Simmons in District 7 that I am a friend of Sam and I need to find him if I have something to do."

The soldier became serious in an instant, raised his gun at Song Qingge and several people, "Who are you? There is no seventh district here, and there is no Simmonsteer. Leave immediately, otherwise I will shoot!"

"Ah, commander, I just said that this method doesn't work, do you need our help?" Prince Eugen smiled.

Song Qingge shrugged, "Then there is no way. Toast and drink fine wine, just stun them."

As soon as Song Qingge's words fell, a figure rushed up and hit the soldier's neck. Then the soldier dropped his head and passed out.
