In the blink of an eye, one year of practicing at Hyperbolic Time Chamber has passed.
It seems that due to the effect of gravity, the time to compress the battery liquid becomes faster.
In just one year, more than half of the concentrated battery fluid has been accumulated. It is enough for Son Mirai to go back to the past, but Son Mirai has to let Trunks drive Time Machine back, so it is necessary to leave enough for the return journey.
Moreover, since he was practicing at Hyperbolic Time Chamber, he was basically not afraid of wasting time, so Son Mirai promised Trunks to take him to practice for another year----
Trunks has also made great progress. At least the progress is greater than his own, and he is enough to be his own training partner.
Every battle, Son Mirai has to deal with it seriously.
However, this is better. Only when you have pressure can you have motivation.
In the blink of an eye, another three months have passed.
The two are fighting again.
The battle is no longer a one-sided crushing.
Trunks has been able to keep up with Son Mirai's speed and can take most of Son Mirai's attacks.
After hundreds of rounds of fierce fighting, the two distanced themselves to rest.
This is also taught by Son Mirai. After all, Trunks has no helpers at all, so he even deliberately keeps a safe distance to rest during training.
Trunks gasped for breath, with a lot of bruises on his body and a trace of blood spilling from the corner of his mouth.
The situation of Son Mirai is not much better.
His breathing was also somewhat disordered, fine beads of sweat oozed from his forehead, and his chest rose and fell slightly.
"Great progress."
Son Mirai gave a rare compliment and said, "Three months ago, you couldn't even catch my ten moves. Now it's not easy for me to beat you——"
Trunks grinned and wiped the blood from the corner of his mouth. "It's all Mr. Son Mirai who taught me well."
"Don't flatter me."
"Go on!"
The two rushed towards each other again, fists and kicks pouring out like a violent storm!
"Bang! Bang! Bang! Bang!"
As time went by, their movements began to slow down, their breathing became heavier and heavier, and sweat covered the ground under their feet.
Another punch!
The two of them were knocked back at the same time, kneeling on one knee, breathing heavily.
Trunks felt that his arms were shaking, and his muscles were so sore that they seemed to be torn apart.
But when he looked at Son Mirai, he found that Son Mirai was in a similar condition.
This is the first time that he has really pushed Son Mirai to this point.
Trunks secretly encouraged him. "We must persist, Trunks, and we must not fall before the enemy----"
At this moment, Son Mirai suddenly stood up straight.
He moved his body and said, "It won't work this way. It will consume too much money to kill the enemy instantly, which is not conducive to a protracted war----"
Trunks was startled and asked, "Mr. Son Mirai, do you mean that's the end of the day?"
Son Mirai shook his head. "No, I mean, another way----"
He closed his eyes and took a deep breath.
Trunks looked at him blankly, not knowing what he was going to do.
Then, Trunks felt the breath on Son Mirai's body began to fluctuate up and down.
Soon after, Son Mirai opened his eyes.
At that moment, Trunks felt that Son Mirai's whole person had changed.
The golden flames burned again, but this time, it was completely different!
The hair strands of Son Mirai stand upright, each strand contains the power of thunder!
His whole body was surrounded by crackling arcs of electricity, and his emerald green eyes shone with an unprecedented sharp light!
Seeing Son Mirai's state and feeling his powerful aura, Trunks's eyes widened and he froze in place.
Son Mirai looked down at his hands, feeling the surging power in his body, and a trace of surprise flashed in his eyes.
"It's really incredible. I tried to save my energy as much as possible, but in the end I broke through----"
Not through anger, not through life and death fighting, but through training and fighting, and taking that step naturally.
Trunks asked, "Mr. Son Mirai, is this Super Saiyan 2?"
Son Mirai nodded. "Yeah."
Trunks said in surprise, "You are too strong. Compared with you, my progress is simply not worth mentioning."
Son Mirai looked at him, was silent for a moment, and said, "Do you know how I broke through?"
As soon as he learned it, he wanted to teach him again, and there was a trace of expectation on Trunks's face.
"How did you break through?"
"It's because of you."
"What, because of me?" Trunks asked in surprise.
Son Mirai nodded and explained, "For more than a year, you have practiced hard and made progress. Especially recently, every battle between you and me has almost forced me to use my full strength.
At that moment, I was thinking about how to continue fighting you with less consumption, and then I made a breakthrough."
Son Mirai paused and continued, "Without your three months of training, it might have been a long time before I could take this step."
"Really?"
Trunks was stunned.
Son Mirai stretched out his hand, patted Trunks on the shoulder, and said, "Don't underestimate yourself, you are progressing faster than me.
If you can continue to practice like this, even if you don't experience any major stimulation, you should be able to reach my state within three years."
Trunks stared at him blankly for a long time before a smile appeared on his face.
"Thank you, Mr. Son Mirai."
Son Mirai took back his hand, turned around and walked towards the rest area.
"Get some rest and continue tomorrow."
Hyperbolic Time Chamber has not been transformed and can only be here for two years for the time being. When the time is up, the battery should be fully charged, and Son Mirai is about to leave this time and space.
He tried not to waste any time.
In the blink of an eye, Hyperbolic Time Chamber's two years have run out.
The concentrated battery fluid is basically full, and there is still enough left to go back and forth anyway.
Son Mirai and Trunks walked out of Hyperbolic Time Chamber and went straight to the Hoi-Poi Capsule house of Bulma.
"Mom, we are back----"
Bulma looked up at Trunks and Son Mirai, and said with a smile, "It's out again!"
I have prepared new battery fluid and some canned food for you——"
They practiced for at least three months in Hyperbolic Time Chamber, but for Bulma it was only a few hours. He was busy preparing supplies for them, but she was too busy.
Son Mirai waved his hand and said, "No, Bulma, we have been going back and forth for two years, and the concentrated battery fluid is almost full----"
Bulma blinked in surprise.
"Has it been two years?"
Son Mirai nodded. "Yes, so it's time for me to leave, and it's time for us to say goodbye----"
"Then - are you coming back?"
Bulma felt ridiculous after asking this question, and immediately rubbed his hair and smiled bitterly, "Oh, look what stupid question I asked?
You've already gone back to your own time and space, why are you coming back? I'm the one talking too much, hehehehe--
Son Mirai looked at her smiling awkwardly, her eyes softening a bit.
"Bulma, if you need any help in the future, I will come back. You must take care of yourself."
Bulma was stunned for a moment, then burst out laughing.
"Oh, what are my mother-in-law and mother-in-law doing----"
