Dragon Ball: I have the wrong system and I have entered the wrong world

"How is Dad? Is he okay?" Son Gohan asked Chi-Chi.

"Don't worry, your father is fine. He is lying in bed resting. You'd better not disturb him." Qiqi took a sip of water and explained the condition of Sun Wukong.

"By the way, Mom, Dad's heart disease is viral. You should take some medicine just in case." Son Gohan said to Chi-Chi.

"Haha, our Gohan is the best boy as expected. Don't worry, I have also thought about this situation. I have already taken medicine." Chi-Chi said happily when she saw that her son cared so much about her.

"I have an idea now. Everyone, help me think about the feasibility of this method. If I take a time machine and travel back to the time when Dr. Gallo had not yet debugged No. 17 and No. 18, I will kill Dr. Gallo first... This means that I already know the location of Dr. Gallo's research institute..." Big Trunks said after thinking for a while.

"Haha, that's a good idea. He's Bulma's child, indeed. He's very smart." Chi-Chi said to Trunks.

"I just realized after writing this that I don't know where I put Yamcha. I don't remember what he is doing in this book. Forget it, it doesn't matter. Just think of him as playing with Ajirobe. Anyway, he has nothing to do with the Cell arc."

Yamcha: Is there no one speaking up for me? {{(°△°; \“}}!

"Wait a minute, is your time machine 100% accurate? I've also heard from Goku that it's very difficult to generate the energy for a round trip." Krillin looked at Trunks with a serious face when he heard this.

"Will you be able to return to the future by then?" Krillin continued to ask. It was better to ask clearly about such dangerous matters. If something dangerous happened on the way, no one could save him.

"This..." When Trunks heard Krillin mention this, he was a little hesitant.

"Also, I have a question. Suppose, if Trunks went to the time before Dr. Gero captured all kinds of innocent people and transformed them into androids, and then killed him, what would happen to his sister and the other androids now? Would they disappear out of thin air?" Son Gohan also expressed his doubts, pulling everyone's thinking in the right direction.

"Oh, I forgot to tell you that even if I went back to the past and successfully killed Dr. Gero, I can only save the future of that world. The androids in this world have already appeared, and I can't change it." At this time, Trunks suddenly remembered that there was such an important information that he had not told everyone.

"What's going on?" Krillin looked at Trunks in surprise, wanting to hear his explanation.

Originally, when Chi-Chi heard Son Gohan say "sister", she was about to ask what was going on, fearing that he would be led astray by the bad women outside and become a bad boy, but she was interrupted by Trunks and Krillin, so she temporarily suppressed the idea.

Chi-Chi thought about it and decided that after all, Son Gohan was relatively obedient, had good grades, and was a strong-willed person, so there shouldn't be any problem. Plus, there were guests at home, so it wasn't really appropriate to discuss such family matters right now. So she planned to wait a while before asking Son Gohan alone about the so-called "sister".

"For example, I brought a special medicine from the future and saved Son Goku in this world...but in the future world I live in, Son Goku still died of a heart attack. In other words, two futures exist at the same time, and our actions will only form one more future." Trunks said slowly, looking out the window.

"Wait, wait! That is to say, even if we really destroyed the androids in this world, will androids still exist in the future world where you live?" Krillin said, sorting out his thoughts.

"Yes..." Big Trunks said, looking down.

"If that's the case... then why did you come to this time and space? Your life won't change at all." Qiqi asked very confusedly.

"It's because of mom... Mom doesn't want to see androids destroy the world, so she hopes for a peaceful world. But there is one more very important point, which is that in the battle between everyone and the androids, I want to find a way to find the weaknesses of the androids!" Trunks also stated the main reason why he came to this time and space.

"That's a good idea indeed." Klin said, stroking his beardless chin.

"If that doesn't work, we can only let Sun Wukong take a time machine to the future to destroy the androids... However, there is a very important thing that bothers me now, that is, what is happening now is very different from what I know about the past." When Trunks said this, his expression became a little serious.

"First, there was Brother Gohan. He was able to turn into a Super Saiyan before Frieza and his son came to Earth. Then, my father was able to turn into a Super Saiyan. If you don't count me, you actually have three Super Saiyans at the same time. I think, even if I hadn't come to this time and space, you would definitely be able to destroy the evil androids."

"Son Wukong's illness time has also changed, and several androids that I have never seen before have appeared..." Big Trunks continued.

"Why is this happening?" Klin asked in confusion.

"I don't know...how could it turn out like this...did I change history? No, I wasn't there when Brother Gohan became a Super Saiyan." Big Trunks thought about it over and over, but still couldn't figure out why history had deviated so much. He could understand everything else, but he had no idea why Son Gohan could become a Super Saiyan.

"It's strange that you can figure it out. I'm not the same Son Gohan as before." Son Gohan curled his lips in his heart, but in reality he still maintained the same expression as before.

"Don't be discouraged. If it weren't for you, I would have died long ago. Gohan and I should thank you very much. As for the android from your time and space, you can just ask him for help when the time comes. I don't think he will refuse something that requires a fight." Chi-Chi was also comforting Trunks. After all, since he saved Son Goku's life, Trunks could be said to be the benefactor of their family.

"Yes, we will always find a way, hahaha!" Krillin also encouraged Trunks.

"There will always be a solution!" Trunks also cheered himself up.
