Could it be that this was the direction of the movie's future development?
At this moment, Optimus Prime couldn't stand the bull Demon King's arrogance anymore. He drew out his sword and pointed it at the bull Demon King. Sir, you're too arrogant. I, Optimus Prime, have met many enemies, but they have all fallen under my axe.
The bull Demon King did not seem to be used to Optimus Prime's temper. He said coldly, " it just so happens that I want to see what you're capable of. Today, I'm going to attend my brother, the great sage, heaven's equal's banquet. Tomorrow at this time, at the end of the fifth ring outside you city, see you there.
if you're afraid, you don't have to come. But in the end, you'll be finished. After bull Demon King finished speaking, he ignored Optimus Prime and turned into a car, leaving in a hurry.
There was a traffic jam on the road, but once it was impossible to pass through, he transformed into his transformer form and jumped over.
