The Past Cannot Be Undone, the Future Can Be Changed

Son Goku looked at Trunks's confused expression and said, "Trunks, I think you must have traveled to a parallel world instead of going back to the past."

Trunks said, "Uncle Goku, how do you make that of it?"

Son Goku said, "Trunks, you should have heard of the theory of Parallel Timelines, right? The development of a world often produces different results due to different processes, and every one of those worlds with different results is a parallel time and space."

Trunks came to a sudden realization and said, "I see. Uncle Goku means that this world can be considered a Parallel Timeline to my original world, rather than the past of my original world."

Son Goku said, "Not bad, and Trunks, I can tell you that your idea of changing the future by going back to the past cannot be realized."

Trunks hurriedly asked, "Uncle Goku, why do you say that?"

Son Goku said, "Trunks, have you ever seen a river flowing backward?"

Trunks said, "No, what's wrong?"

Son Goku said, "Time is just like a long river. From the moment it flows, there is no possibility of turning back. It will only keep flowing forward until the end. Therefore, the world you traveled through time to return to is not the world of the past, but has recreated another parallel world."

Trunks said in agony, "Uncle Goku, is there really no way to change the tragedy of my original world?"

Son Goku said, "Trunks, remember one sentence: the past cannot be undone, the future can be changed."

Hearing this, Trunks pondered for a moment and said, "Uncle Goku, I understand."

Son Goku said, "It's good that you understand. After Vegeta eliminates King Cold and Cooler, I will accompany you to your world to eliminate the Androids."

Hearing this, Trunks said, "That's great, Uncle Goku. With you accompanying me, we will definitely be able to eliminate the Androids."

Son Goku said, "Trunks, I can help you once, but can I help you all the time? Your world is ultimately meant to be guarded by you."

"But my strength is very poor, and I don't know how to train either. I am able to have the strength I have today, and I owe it all thanks to Gohan's guidance over the years. But Gohan was killed by the Androids in order to save me," Trunks said.

Son Goku said, "Don't worry about that. Once we go to your world, I will guide you in your training."

Trunks said, "Then thank you very much, Uncle Goku."

Son Goku said, "Don't mention it. Come to think of it, you are also Bulma's child. Even though you are not from the same world, you are still somewhat related. I couldn't just stand by and watch."

Hearing this, Trunks nodded and said, "No matter what, I still have to thank Uncle Goku."

Son Goku nodded, and then said to Trunks, "Take a look at the battle between Vegeta and Cooler. It will be of some help to you."

Trunks nodded, and then the two of them looked at the battle between Vegeta and Cooler.

During their conversation, Cooler had already been beaten black and blue, covered in bruises and battering by Vegeta.

Although Cooler's fourth form was higher than Frieza's, it was only one hundred and sixty million, and he was far from being a match for Super Vegeta.

You must know that when Vegeta transformed into a Super Saiyan, he had a battle power of five hundred million, and finishing off Cooler in seconds was a piece of cake. The reason he didn't kill Cooler was because Vegeta wanted to thoroughly ravage Cooler to repay all these years of "kindness" Frieza had shown him.

As the saying goes, a father's debts must be paid by his son, and in Vegeta's view, there was nothing wrong with that.

At a certain time period in a parallel timeline, Paragus and Broly thought the same way too.

Cooler was beaten into a fit of rage by Vegeta. After putting some distance between them, he said to Vegeta, "Damn Saiyan monkey, you have successfully angered me. This king has decided not to hide his strength anymore, and I am going to activate my Ultimate Form."

Hearing this, Vegeta sneered and said, "Do you have other transformations? I remember Frieza's Ultimate Form is just what you look like right now, isn't it?"

Cooler said, "Do you think that I am like my foolish younger brother, only able to undergo three transformations? I am a genius of the Frieza Race, so naturally I should have one more transformation than Frieza and my father King Cold, and be stronger than them."

"Oh, is that so? Then transform and let this prince see just how strong you can be in your Ultimate Form," Vegeta said.

"Fine, Vegeta, just wait. I hope you won't regret it later," Cooler said.

With that, he began his ultimate transformation.

They saw Cooler's aura surge violently, his physique grew a size larger, four horns grew out of his head, his mouth was covered by a "mask", his eyes turned red, his pupils disappeared, the bones on his shoulders bulged, and sharp bone blades grew out of his elbows.

Once the transformation was complete, Cooler's aura had increased by nearly three times compared to before.

King Cold down below saw this and was greatly shocked. He had never seen this form of Cooler before, and he muttered to himself, "It seems I really didn't do wrong by having Frieza hold Cooler back before. This brat is stronger than both me and Frieza. If it weren't for Frieza, I'm afraid my empire would have been overthrown by him long ago. However, there's no need to suppress Cooler anymore now. Once we wipe out this group of people this time, I'll hand the empire over to Cooler."

Trunks felt Cooler's aura and said in shock, "This Cooler's aura has become much stronger than before. Will Vegeta be alright?"

Son Goku said, "Rest assured, Trunks. Vegeta was just warming up a moment ago and didn't bring out his true strength at all."

Trunks said in surprise, "Uncle Goku, I really don't know how you guys train. If my father had the strength of the father in your world, the Androids wouldn't be anything to fear at all."

Son Goku said, "Once I pass the training methods on to you, you will also be able to reach Vegeta's strength, and even surpassing Vegeta's strength won't be a problem."

Hearing this, Trunks looked forward to the training methods Son Goku mentioned even more.

In the air, Vegeta felt Cooler's aura and sneered, "I thought your final form could be how strong. It turns out to be nothing much. With this bit of strength you still dare to make wild arrogant claims in front of this prince? This prince will let you see my true strength."

With that, he let out a loud shout and began to raise his own strength. They saw that the golden aura surrounding Vegeta grew increasingly intense, and his aura was twice as high as before.

Vegeta released all of the Super Saiyan's strength, and his battle power reached five hundred million.

Seeing this, Cooler said in great shock, "Impossible, absolutely impossible. In the battle just now, you actually weren't using your full strength."

King Cold down below felt Vegeta's strength and cold sweat poured down, pondering whether he should slip away.

But after careful consideration, he still decided to assist Cooler from the side later, launch a sneak attack to finish off Vegeta, and then the father and son would join forces to eliminate the other Saiyan. That way, the others wouldn't be anything to fear.

Otherwise, if he fled right now, he would instead be picked off one by one by the two Saiians.
