After Bulma finished speaking, she hurried back to her laboratory and began searching frantically.
"It's in this room, but where did I put it?" Bulma shouted as she searched.
Suddenly, Bulma shouted, "Ah, I found it, this is it!" After that, Bulma rushed out of the room again, holding a capsule high in her hand.
With a "bang," the capsule opened, and a time machine covered in moss and with a large hole in its glass dome appeared before everyone.
"This is..." Future Trunks looked at the time machine and was about to speak.
But Bulma interrupted, saying happily, "That's right, this is the time machine that Cell used to travel back in time. When you left, I took it."
Holding up her notebook, Bulma continued, "Now that we have this machine and the notebook, we can repair the time machine."
John Doe, Goku, Vegeta, and Future Trunks all cheered happily. John Doe said, "This is great! I must go and beat that Black John Doe senseless for taking over my body."
The atmosphere of sadness that had filled everyone's hearts was instantly dispelled. Without further ado, Bulma took everyone to repair the time machine.
Future Trunks, John Doe, and Goku discussed Black John Doe's strength.
Future Trunks asked Goku, "Uncle Goku, what do you think of Black John Doe's strength?"
Goku replied, "His strength is indeed impressive. In his base form, he fought evenly with my Super Saiyan form, which is quite formidable."
"Then, then, then, Uncle Goku, can you defeat him?" Future Trunks asked eagerly.
Vegeta spoke up at this point, "Don't worry, do you think the power Goku just displayed was our full strength?"
"I'll show you our true strength. Come with me," Vegeta said, leading the way into the depths of the garden. Future Trunks followed behind Vegeta, encouraged by Goku and John Doe.
Goku had already demonstrated their strength in base and Super Saiyan forms to Trunks. Now, in the garden, Vegeta couldn't wait to show Trunks their ultimate power.
Vegeta said to Future Trunks, "Trunks, watch closely. The transformation I'm about to show you will be the direction of your future efforts. If you want to protect your future from evil attacks, you must keep improving."
"Ha!" With a roar from Vegeta, a blue cyclone appeared around his body, spinning around him.
The cyclone then turned into blue flames, and Vegeta's entire body was enveloped in blue light. As the blue light peeled away from Vegeta's body, Trunks saw a new image of Vegeta with blue hair, eyebrows, and eyes.
In Future Trunks' perception, the once formidable aura of Vegeta disappeared.
"What transformation is this?!" Future Trunks exclaimed in shock.
"This is the Super Saiyan transformation with the power of a god, which we call Super Saiyan Blue," Vegeta explained.
Looking at his son's extremely shocked expression, Vegeta smiled coldly and said, "Do you want to test my strength?"
Trunks hesitated for a moment, then nodded.
"Good," Vegeta shouted. "Transform into Super Saiyan 2 and attack me with your full power."
Future Trunks immediately transformed into his Super Saiyan 2 form, and the golden flames around him spread out like sword beams, flashing with arcs of electricity.
Vegeta waved his hand at Future Trunks and said, "I'll let you attack first."
After the previous sparring with Goku, Future Trunks was well aware of the incredible strength of Vegeta and Goku. Facing Vegeta's invitation to attack, Future Trunks dared not relax.
He swung his sword and charged at Vegeta, dragging a white arc of electricity behind him.
"It seems like this is Trunks' full-power attack!" John Doe commented.
However, Vegeta didn't seem to care about Future Trunks' full-power attack at all. He didn't even dodge, and just as Future Trunks was about to strike Vegeta, Vegeta quickly moved in and struck Trunks' abdomen with an elbow.
The powerful attack hit Future Trunks, and a blue light shone through his body from behind.
Future Trunks didn't even have time to cry out in pain. He spat out blood and lost consciousness.
Seeing this, John Doe couldn't help but feel a sour taste in his mouth. "Vegeta, that was too much. He's your son, and you used so much force against him."
Vegeta replied, "I just want him to know the right path to take and not to keep going down the wrong path. Give me a Senzu Bean."
John Doe looked at Vegeta's stern face and shook his head helplessly. Then he took out a Senzu Bean and handed it to Vegeta.
Vegeta fed the Senzu Bean to Future Trunks, and after a while, Future Trunks stood up again.
Future Trunks rubbed his abdomen, which had just been hit by Vegeta. Although the Senzu Bean had healed him, he still felt the pain from before.
Vegeta looked at Future Trunks and said, "Trunks, remember that pain and work hard to become stronger. Don't keep pursuing Super Saiyan transformations; work on transforming into Super Saiyan Blue."
Future Trunks nodded firmly and said, "Yes, Dad."
From the time Future Trunks arrived to the moment Black John Doe traveled through time and destroyed the time machine, only about an hour had passed.
Soon, others gradually arrived, including Krillin, Yamcha, Tien Shinhan, Piccolo, Gohan, and Android 18.
Android 18 approached Future Trunks with Axel Doe and greeted him, "Hi, Trunks, have you already eliminated that future person of mine?"
Looking at Android 18's serious and coldly beautiful face, without a hint of a smile, Future Trunks felt embarrassed. However, he nodded and admitted it.
At this moment, John Doe walked over, put his arm around Android 18's shoulder, and said, "It's okay, don't scare him. He's already feeling very sad."
Future Trunks looked at John Doe and Android 18, then at Axel Doe, and was suddenly surprised. Pointing at Axel Doe, he exclaimed, "This is your child? But Android 18, aren't you an android?"
Android 18 replied speechlessly, "I'm an android based on a human body, not a robot. I'm a person first, and people can have children."
Future Trunks felt embarrassed and scratched his head. Then he apologized for his rudeness.
