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

"What are you doing, Trunks?" Bulma looked at Big Trunks in confusion and asked softly.

"Mom!" Hearing this extremely familiar voice that he hadn't heard for a long time, Trunks was shocked and turned around suddenly.

When he saw Bulma's familiar and kind face, Trunks' eyes instantly became moist and tears slid down his cheeks uncontrollably.

"Mom, you're still alive..." Trunks' voice choked with sobs, and his trembling hands gently stroked Bulma's face, as if he was afraid that all this was just an illusion.

Seeing Trunks suddenly burst into tears, Bulma couldn't help but frown.

"What on earth happened? Trunks." Vegeta, who was standing aside, was also very confused, with worry in his eyes.

Trunks took a deep breath, trying to calm himself down, and then said excitedly: "Great, I successfully went back to the past."

At this time, Beerus, who had been silent all the time, suddenly spoke up and asked Trunks next to him: "Hey, kid, your name is Trunks too, right?"

Trunks looked at Beerus in surprise. Although he didn't understand why he asked that, he nodded and replied, "Yeah, yes."

"So that's how it is. He traveled through time." Weiss also said seriously.

"I'm fine. I'm sorry, Mr. Goku."

Trunks adjusted his emotions, bowed his head and apologized to Son Goku.

"Was it done by Majin Buu? The guy who hurt you." Son Goku's expression became extremely solemn. He frowned and stared at Trunks in front of him.

Trunks shook his head slightly and answered firmly, "No, I have already defeated Dabura and Babidi, and successfully prevented the resurrection of Majin Buu."

"What? Really?" After hearing this, Sun Wukong showed a hint of surprise on his face. He widened his eyes and asked in disbelief.

"Of course, this is also thanks to the help of Lord Kaioshin." Big Trunks nodded affirmatively and added.

"Huh, he is my son after all." At this time, Vegeta, who was standing aside, raised his head proudly and said with satisfaction, with a proud light flashing in his eyes.

"Son... As expected, this one is also..." Pilaf and his gang stared at Trunks in amazement, their mouths opened wide with shocked expressions on their faces.

"Is he really an illegitimate child?" one of them stammered.

"Wait, wait, you are the kid from the future!" Suddenly, Beerus pointed his finger at Trunks next to him and said to Big Trunks with a serious expression.

"Well, yes, you are..." Big Trunks nodded, his heart full of doubts. He looked at Beerus carefully and asked curiously.

"Eh?!"

Trunks opened his mouth in surprise when he heard this.

"Oh my, I'm really shocked. I didn't expect that humans could actually create such a machine! Originally, I always thought it was absolutely impossible to achieve."

At this moment, Weiss's eyes were fixed on the mysterious [Time Machine] brought by Trunks, his eyes full of surprise and curiosity.

Bulma put her hands on her hips triumphantly, a proud smile on her face.

"Haha, this was created by my future self. Isn't it awesome?"

She seemed extremely proud of her accomplishments.

"Ms. Bulma, don't you know that manipulating time is a felony that cannot be tolerated in the entire universe?" However, Whis's expression became extremely serious, and he solemnly warned Bulma.

"Even if you are destroyed, you can't have any complaints." Beerus on the side also showed dissatisfaction and echoed Whis' words.

Bulma panicked when she heard this. She quickly explained, "Wait, you're wrong! I didn't do that. No... To be precise, that was a work created by my future self. It has nothing to do with me now!"

Her tone seemed a little hurried, trying to distance herself from the matter.

"Trunks! Who are the enemies?" Vegeta asked Big Trunks again.

Big Trunks' eyes were equally serious. He took a deep breath and said slowly, "He said... he wanted to wipe out all the humans on Earth for justice."

"He has destroyed the entire planet, killed all the humans on it, and fought them for a year. Now there is almost no one alive... Not even mom..." said Big Trunks with a depressed look on his face.

"What? Even I was killed?" Bulma said in surprise.

Vegeta was shocked when he heard this, his eyes widened and veins bulged on his forehead.

"Hey, who the hell is that bastard?!"

Vegeta's voice unconsciously rose an octave, revealing his inner anger.

"The enemy is Mr. Goku..." Big Trunks whispered.

"Eh? Me?" Sun Wukong pointed at his nose and said in disbelief.

"Ah, no, it's someone who looks exactly like Mr. Goku." Seeing that what he said was ambiguous, Trunks hurriedly explained.

"what?"

"Really? What's going on?"

The rest of the people were even more confused when they heard the news.

"But isn't Goku dead over there?" Bulma asked hurriedly.

"I don't know exactly what's going on, but he really looks exactly like Mr. Goku... My cruel personality is completely different." Trunks said in great confusion.
