Super 17 Saga
After Dr. Myuu died, he met Dr. Gero in Hell. The two created the Ultimate Android, Super 17, and opened a gate from Hell to Earth, where it merged with the Android 17 already on Earth to become Super 17. The other Dragon Ball warriors were no match for him, and even Goku, transformed into a Super Saiyan 4, remained at a disadvantage. In the end, Android 18 disrupted 17, and only then did Goku manage to destroy him with the Dragon Fist and a Super Kamehameha.
Evil Dragon Saga
After the Super 17 saga, Goku and the others intended to find the Dragon Balls to restore Earth, but this time they summoned the Evil Dragons. It turned out that because the Dragon Balls had been used too much since the beginning, they had turned evil. Goku volunteered to defeat the seven Evil Dragons to restore the Earth. After Omega Shenron was defeated, all the negative energy was purified. Shenron appeared suddenly after the great battle, restored the Earth to its original state, and then took Goku away. The Dragon Balls did not appear again for nearly a hundred years!
"Looks like I'll have to go to the Hyperbolic Time Chamber again.
But if I go alone, the results won't be as good."
Lei Chen thought to himself. Right now, Lei Chen wanted to rapidly increase his base combat power, and for the Saiyan physique, the best results come from training through combat.
At this moment, Lei Chen suddenly thought of Vegeta.
"Yes, perhaps this is the person who most wants me to come find him."
Thinking of this, a smile appeared on Lei Chen's face, and the next moment, he vanished from the desert.
Bulma's house.
In the gravity training room, a fully enclosed space of about two hundred square meters, the surroundings were filled with training machines.
The light inside was red, and a screen displayed the number 1000. A man approaching middle age was training desperately inside.
Perhaps in the early stages, a gravity room could allow a Saiyan to progress very quickly, but for Vegeta, whose base combat power had already exceeded ten billion, this gravity no longer meant much.
"Damn it, Kakarot, one day, I will surpass you."
Vegeta was drenched in sweat, the floor covered in droplets, as he gritted his teeth and spoke.
Just then, a figure suddenly appeared in front of Vegeta.
"1000 times gravity?"
Lei Chen, having just appeared before Vegeta, immediately felt a powerful pressure acting upon his body, the immense force nearly forcing him to his knees.
"Ugh!"
Lei Chen gritted his teeth, barely resisting the urge to transform into a Super Saiyan.
Vegeta was stunned; he hadn't expected Lei Chen to appear before him so suddenly, but seeing Lei Chen nearly make a fool of himself, his previously grim expression finally broke into a smile. "I can't tell, your power when transformed into a Super Saiyan 4 is impressive, but your strength in your normal state is actually this weak."
"Give me a break, you've had ten more years of training than I have. You should know that in my era, your power wasn't even as high as mine."
Lei Chen said, annoyed.
Vegeta's face darkened. The version of himself from the other world wasn't as strong as this guy, which made Vegeta's face, which had just shown a hint of a smile, turn black once again.
"Speak, why have you come to find me?"
Vegeta regained his cold expression and said to Lei Chen coldly.
"Heh, do you want to go to a more effective place to train? You should know that this training room can no longer increase your power in the short term."
Lei Chen said to Vegeta.
"Where?"
A flash of joy crossed Vegeta's eyes, his expression improving significantly as he looked at Lei Chen.
"The Hyperbolic Time Chamber. Training with two people is better than training by yourself, right?"
Lei Chen laughed.
"Fine!"
Vegeta replied.
Another two days passed.
Hyperbolic Time Chamber.
"Strange, why has your power weakened so much?"
Vegeta, in his Super Saiyan 2 state, looked at Lei Chen with a strange expression.
Although Lei Chen's combat power was still stronger than his, it was nowhere near as terrifying as it had been when he fought Super Saiyan 4 Son Goku; at the very least, it was ten times weaker than before.
