Training can be quite boring, but no one felt bored when they had made up their mind.
In the blink of an eye, three months have passed.
On Trunks' side, Vegeta and Future Trunks have roughly understood the key to surpassing the Super Saiyan limit and started their own training.
On Piccolo' side, they have also mastered the essentials of Kaio-ken and started training with higher multiples as their goal.
As for Gohan and Lazuli, they have also both made good progress.
In addition to these Z warriors striving for the future of the earth, in the mortal world, ordinary humans were also struggling to rebuild the human world.
When Bojack occupied Earth, there was actually a considerable number of Earthlings who voluntarily joined him.
This pirate from the milky way galaxy was originally a guy who worshipped power and evil. He enslaved humans but also attracted those humans who already liked violence and chaos to him.
Therefore, Bojack also gathered a considerable number of villains and ruffians under his command.
The humans slaughtering each other that Lin Chen saw when he first arrived in this world were actually battles between these ruffians and the rebel army.
After Bojack and his gang died, those ruffians continued their past habits and kept attacking the remaining human settlements, although they did not know why their leader had suddenly disappeared.
When Lin Chen was guiding the Z warriors' training, the rebel army on the ground, led by Satan, Videl, and Turtle Hermit, fought against and suppressed the ruffians, rebuilding human society's order.
For the sake of convenient publicity, they even claimed to the outside world that Bojack died at the hands of Satan, rallying everyone together under the banner of the hero Satan.
This trick was very effective, and wherever the rebel army went, there were constantly desperate survivors joining them.
In two months, many places had fallen into the hands of the rebel army, and the speed of restoring order was constantly increasing.
Seeing that everything on Earth was going well, Lin Chen prepared to temporarily leave and retrieve the seventh super dragon ball.
"Lin Chen, are you leaving?"
That day, while Lin Chen was gathering supplies in the mortal world and preparing to go into space, Lazuli, who should have been training on Lookout, suddenly approached him.
"I'm just going to travel in space. I came to this world to find something, and it's not on Earth."
Lin Chen didn't explain much.
He turned his head and asked Lazuli, "What's wrong? Are you afraid I won't come back?"
"No, I'm just curious about the world outside of Earth."
Lazuli brushed back her hair and said, "You may not know, but I once talked with Lapis…..Oh, he is Android 17, we once talked about what we would do after killing Goku and completing our programmed order."
"Lapis said he wanted to go see animals, while I wanted to travel through the universe and visit different planets."
"Now I've changed my mind a bit. Compared with different planets, different worlds seem more interesting."
"Lazuli, what are you..." Lin Chen suddenly realized that Lazuli's words seemed to contain a hidden meaning.
"Lin Chen, when you leave this world, can you take me with you to see it?"
"Well..."
Lin Chen hesitated for a moment, then shook his head and said, "I'm afraid not. I use a special power to travel between worlds, and it can only take me, not anyone else."
"Oh..."
Lazuli nodded, but there was no expression of regret on her face.
"Well, then I'll have to think of another way."
"Sorry about that." Lin Chen apologized and said goodbye to Lazuli.
Lazuli silently watched Lin Chen disappear, straightened her drooping clothes, and then turned to look in the direction of West City.
In West City, the rebel army had established a stronghold and was planning to build a new city that symbolized a new order for humanity. Bulma and the others were all gathered there.
...
After leaving Earth, Lin Chen constantly jumped through space and occasionally used the dragon ball radar.
After a month of searching like this, Lin Chen finally found the missing seventh Super Dragon Ball in an endless darkness!
Carefully keeping the Super Dragon Ball, Lin Chen thought for a moment and then went to the Sacred World of the Kai.
However, the place where the Sacred World of the Kai should have been was actually empty.
Looking around at the void, Lin Chen wasn't surprised.
Going to the Sacred World of the Kai was just a plan that Lin Chen had made on a whim.
This was already the second parallel universe that Lin Chen had crossed to.
On the surface, these two worlds should have been parallel universes. Besides the difference in historical trends, everything else should have been the same.
But Lin Chen discovered that these two worlds seemed to have other differences from his own world.
That is the layout.
For example, there is no Sacred World of the Kai in the 228th World where Lin Chen currently is.
And without the Sacred World of the Kai, there could be no God of Destruction's Planet.
Thinking further, Lin Chen couldn't help but wonder if this world might only have one universe, unlike the Dragon Ball world in the original work, where there are twelve universes in existence.
So the layout of this world is actually much smaller than Lin Chen's world.
Why is there such a huge difference between the two worlds? Is there also a classification distinction between worlds?
Lin Chen felt that there is an underlying secret within.
"Forget it, these are not what I should be concerned about now. I should go back and see how Trunks and the others are doing. When this mission is completed, it will be time for me to go back."
Leaving this void space, Lin Chen returned to Earth, where everyone's training was still continuing.
So just like this, the last few months passed.
On this day, everyone gathered in front of the Hyperbolic Time Chamber.
Today is the day mentioned by Shenron when Cell returns to Earth.
At the same time, it is also the day when Vegeta and Future Trunks, who entered the Hyperbolic Time Chamber again, will come out.
The group plans to wait for them to come out and then head to the 28KS5, northwest of Central City, which is the first place predicted by Shenron that Cell will appear after his return to Earth.
"Hey, how come Vegeta and the others haven't come out yet? They couldn't have forgotten that today is the day Cell is coming, could they?" Piccolo calculated the time and said anxiously.
"They won't, Uncle Piccolo. Dad and the other me have been preparing to take revenge with all their might. They won't miss this day," Trunks said, and just as he finished speaking, everyone sensed two astonishing auras.
"Is that Vegeta and Future Trunks? They have become so strong," Recognizing these auras, Piccolo said in astonishment.
