I will give you the lines:

1. Optimus: The code...the code on these glasses indicates the All Spark is 230 miles from here.

Optimus Prime: The code... The code in the glasses shows that the source of the AllSpark is 230 miles away from here.

Ratchet: I sense the deceptions are getting ready to mobilize.

Ratchet: I sense the Decepticons are getting ready to mobilize.

Ratchet: I sense the Decepticons are getting ready to mobilize.

Ironhide: They must know it’s here, as well

Ironhide: They must also know that the source of fire is here.

2. Optimus: Were we so different ?They are a young species. They have much to learn . But I've seen goodness in them . Freedom is the right of all sentient beings .You all know there's only one way to end this war . We must destroy the Cube . If all else fails ,I will unite it with the spark in my chest .

Optimus Prime: Didn't we do it before? They are a young race and have much to learn. But I've seen their good points. Freedom is the hope of all sentient creatures ("Freedom belongs to all living beings" is the classic saying of Optimus Prime throughout the ages). You all know there is only one way to end this war. We must destroy the energy body. If all else fails I will combine it with the fire in my chest.

Ratchet: That’s suicide. The Cube is raw power. It will destroy you both.

Ratchet: That’s suicide. The energy of the energy body is very unstable and may cause South Korea and Wei to attack each other.

Optimus : A necessary sacrifice to bring peace to this planet . We cannot let humans pay for our mistakes . It's been an honor serving with you all . Autobots ,roll out !

Qing Tianzhu: For the peace of this planet, sacrifice is inevitable (no matter how Optimus Prime's appearance changes, his philanthropic mind and fearless spirit remain unchanged). We cannot make humans pay for our mistakes with their lives. It's an honor to fight with you till now. Autobots, let’s go! (Isn’t this the sentence that evokes endless memories for us?)

It can be seen from the conversation between Ratchet and Optimus Prime that the energy of the fire is very powerful. Energy is very unstable and has two sides. It has the energy to turn objects into Transformers. Too much energy will also cause Transformers to die (similar to a system crash - -), so Optimus Prime prevents Megatron from getting the energy body. , willing to put the Rubik's Cube into his body.

It is estimated that in the end, Sam thought about the instability of the energy body, and also felt that Megatron could not exist in the energy body. He did not want Optimus Prime to die, so he simply took the risk and stuffed the Rubik's Cube directly into Megatron. Chest.... Turns out he was right.
