Later, although Dr. Daimori's goal was to travel back in time and save his companions and wife, at that time, he could no longer get financial and human technical support, so he could only make changes to the time machine samples that had been developed, and naturally he was never able to make substantial progress. Later, although he didn't have to worry about the funds (the capsule company gave 150 billion), he has been monitored by Gack and the government (Gack doesn't need to say, he really thinks that Guru went to the island to be his companion?), so the research is limited to some theoretical collations. ”

"In short, on the basis of the Dasheng time machine, I completed the practical application of the time machine through the transfer of performance focus, but when it comes to the real ancestor of the time machine, it is actually Dr. Dasheng. ”

After listening to Bulma's talk about the development history of the time machine, Leping was only amazed - not only by Dr. Dasheng's wisdom, but also by Bulma's transformation. Although this girl is very understated, I know with my toes that it will be very difficult to make a little improvement on a high-tech device like a time machine, needless to say that Bulma is a half-finished product of Dr. Daimori...... That scrap product was improved to be practically usable.

However, she didn't talk about her contribution at all, and she opened and closed her mouth with Dr. Daimori, this humble attitude...... It's completely different from the Bulma I knew.

After talking about the history of the development of the time machine, let's talk about the ......

"The success of the time machine has made a lot of things possible. The first thing to do is, of course, the test - I'm not talking about the time machine itself, which was already done back in the Dasheng era. I'm talking about a series of paradoxes or paradoxes based on time travel – do you understand what I'm talking about?"

Feeling as if he was being underestimated, Leping was slightly unhappy - but thinking that the person who underestimated himself was Bulma, this unhappiness disappeared again, and people do have this qualification. So he replied very calmly, "Is it something like the great-grandfather paradox?"

Bulma nodded, "This is it. Well, since you know I won't explain much. After sorting out his thoughts a little, he continued, "It stands to reason that the time machine should complete a series of tests before it can actually be put into use, otherwise it is likely to cause unknowable changes in time and space. However, it is not easy to obtain the energy of the time machine, if you verify all the known paradoxes of time and space, and then want to accumulate enough energy, you don't know when you will have to wait - not to mention, at that time, to go to your side, it is not 'back to 20 years ago', I am afraid it is 'back to 30 years ago' or even '40 years ago'. ”

Speaking of this, Bulma shook her head slightly, "We can't afford to wait. ”

Leping: "......"

"So, we have to rush the time machine to use, as for what impact it will have on history...... To be honest, I don't know, and I can't care about it. Only one thing is certain, no matter what it becomes, it's better than this world ravaged by androids, right?"

Leping glanced at Trunks, and then he understood why this kid had been worried about his appearance. Judging from the development of the story later, whether Trunks appears or not in the main plane will obviously not affect his own existence (otherwise, when Shalu in the main plane is eliminated by Kobayashi and Trunks, the two Shalu in the future space-time should disappear).

It turned out that he wasn't sure.

Then he said some untenable words, until it suddenly darkened outside the window-this is the sun fist released by Leping The energy was exhausted and extinguished-and the three of them went back to their rooms to rest.

At half past four in the morning the next day, when Guixian Liu got up, Leping got up on time. Then, he found that Trunks didn't seem to be up yet.

"This kid ......"

But it's not strange to think that the young man's training was not Kamesen-ryu, but the "piccolo stream" given by Gohan, or an incomplete "crash version". The first step in the crash course is survival training in the wild - no matter who you are, it is estimated that it is difficult for a person to develop a good habit of working and resting on time under the conditions of survival in the wild.

However, people trained in this way must be very sensitive to danger. As long as you suddenly lift your anger......

Forget it, just let him sleep more. Leping finished tidying up, opened the door and went out for a jog.

This is certainly not exercise, it can only be said to be a habit. As for how the next stage of cultivation should be carried out, he already had a plan.

After running around the city (running too fast, even a circle around the city is nothing), and when I returned to the Cupule house, it was almost six o'clock, but the mother and son had already gotten up. Bulma seems to have a good lifestyle and is doing exercises, while Trunks is busy in the kitchen. This child has been thoroughly cultivated into a good family man.

"Good morning. ”

Seeing Leping running over, Bulma took the initiative to say hello.

"You...... Is it really 50 years old?" saw Bulma doing frog jumping with ease, Leping was a little puzzled. Among ordinary people, Bulma's physical fitness is inevitably a little too good. "I don't think you look like you're 50 years old, I thought it was good maintenance, but now it seems that your physical fitness is about 30 years old. ”

This Bulma here was raided by Vegeta, but in her own plane, Bulma was still her girlfriend - more likely to be a lifelong partner.

What man doesn't want his lover to be young and beautiful for the rest of his life?

"Oh, it's the medicine that the old cat found for me, and it's said to prolong people's lives. Because my research is important, the old cat feels the need to keep my body in good shape. Bulma explained casually, and at the end, he did not forget to add, "It is said that this medicine old turtle has also eaten." ”

Leping was taken aback: this ......

I didn't know what to say, but I heard Trunks greet him and went to dinner.

"Mr. Leping, what are we going to do today?" Trunks asked as he ate. Again, the Bulma family doesn't have any rules of "eating without saying a word, sleeping without a word".

"Didn't I tell you a long time ago, just stay in Super Saiyan condition. ”

"Oh......" Trunks nodded, no more.

"But......" Leping thought for a moment, "aside from the practice, we do have some things to do today. ”

————

(Finally, I will spit out: in "Dragon Ball", Trunks' use of the time machine is really problematic, and here is a solution to the android with a time machine: go to Trunks a day ago, and then go two days ago, bring back Trunks two days ago...... By analogy, as long as you can concentrate five Trunks in five different time and space, it is easy to form an absolute advantage over two artificial humans.

In fact, if there is no problem with the time machine, then keep repeating this method, and Majin Buu or everything is a floating cloud.

The ground effect will try to change two times in three days. Let's take it slowly. Three books at the same time, the ground effect is really a bit unbearable)
