As a pirate, he wants to be the king but relies on his son to conquer the world.

After chatting with Robin for a while, Sparrow came out.

When leaving, Sparrow was still thinking, what is the attack method of the space battleship?

The attack of the space battleship wiped out most of the lunar people, which shows that it affected a wide range.

Multiple strikes or one strike?

Is it using an energy attack similar to a laser cannon? Or is it using kinetic energy strikes such as electromagnetic guns? Or is it manipulating weather disasters?

Was the moon originally so desolate, or was it destroyed by the space battleship's weapon system?

Let Einstein analyze these questions.

So, Sparrow walked to Einstein's laboratory.

"Einstein, are you busy?" Sparrow walked into the laboratory without waiting for Einstein to answer.

"What's the matter? Please tell me, Father." Einstein, the Tuntun Man, and the Weapon Man did not look back and were still obsessed with research.

So Sparrow walked up to Einstein and told him about the history of the moon and his speculations, and asked him to help analyze it.

"Okay, I'll tell you after I take a look at the murals and the analysis report on the moon." Einstein continued his research without raising his head.

"Wait a minute! How is the research on the Rainbow Mist? Can its time problem be solved? You must know that it is not many years before the Straw Hat Boy goes to sea, and it will not work if he stays in that space for too long." Sparrow stopped Einstein and warned him.

"No problem, research has made breakthrough progress now.

Through methods such as Devil Fruit and energy injection, time can advance smoothly in the Rainbow Mist. The specific time flow rate fluctuates smoothly back and forth between 1.2 and 5.

He even saved a child who accidentally fell into the rainbow mist decades ago.

Now it comes down to how long your “rebirth” plan will take? "

Einstein finally turned to look at Sparrow and said.

"Really? So fast? Indeed, it's time for me to try the power of "rebirth"." Sparrow said in surprise.

Yes, a gentleman does not stand under a dangerous wall.

How could Sparrow use himself as his first experiment?

Although I have had the experience of giving birth to Lei and Yan, there are still some differences.

Although the feedback given by the Devil Fruit on "rebirth" is OK, it does not tell how long it takes and how much energy it takes.

Sparrow thought for a while, and he really should test it in advance to be on the safe side. If something goes wrong with his rebirth, he would be in trouble. Not to mention wasting an opportunity, it would be really troublesome if there are any sequelae.

So he called a few artificial humans who had exhausted their potential and asked the teleporter to take them and Sparrow to the island in the windless zone.

Sparrow is going to do a control experiment.

He told half of the people about the ability to be reborn, to give them more potential, but he didn't tell the other half.

At the same time, the energy of gestation is also different.

Some simply use the flesh and blood energy of the Neptune class, and just replenish the flesh and blood energy regularly.

Some of them added other things, such as the sword intent of famous swords, or the animal genes and flesh and blood energy corresponding to the animal devil fruits they ate, etc., and even used sea floor stones for gestation.

Sparrow used everything he could think of, and even called Einstein to ask him to make suggestions as well.

"Start!" Sparrow whispered after consulting Einstein, and put them into the artificial "womb" to be reborn together, using Neptune's flesh and blood to breed again.

Then use the ability of the pregnancy fruit to sense.

Without the use of Devil Fruit to accelerate pregnancy, it would be the same as normal pregnancy. In fact, there is not much difference in time. They are all "natural" births in ten months.

Without intervention, it would be the same as being pregnant for ten months.

You must know that Sparrow is going to give birth to himself this time. Sparrow does not dare to speed up for the sake of potential. Although the devil fruit is magical, Sparrow is not omniscient and omnipotent, so it is better to be more stable.

And when Sugar faints in the original work, the Devil Fruit ability will also be released.

This means that Sparrow may have to be pregnant for ten months this time. Coupled with the time flow problem of Rainbow Mist, Sparrow thought that it would take a long time, about 1 to 6 years. was conceived.

At the latest, it will be around the time Straw Hat goes to sea.

Okay, done!

As for the experimental products in front of us, of course it is impossible to completely gestate them step by step.

If we really wait ten months, the day lilies will be cold!

Sparrow used the ability to accelerate gestation. Needless to say, he knew that he must have lost part of his potential, but even so, it took about a month to prepare.

After they were all "born", Sparrow did a test.

From a comparison point of view, the potential of artificial humans who are mentally prepared to know "rebirth" is indeed higher than that of artificial humans who are not mentally prepared.

This shows that in the process of "rebirth", people's subjective initiative has a certain positive impact on the results of pregnancy.

When asked if they were conscious during the "rebirth" process, their answer was yes but in a daze.

Let’s compare the pregnancy effects of different pregnancy methods.

Ordinary artificial humans reborn with Neptune-like flesh and blood energy have strong bodies, and their physical potential generally reaches the general level, which is no worse than the potential of ordinary geniuses in the ordinary pirate world. Compared with before, they have a slight possibility of impacting lieutenant generals and generals.

The kendo talent of the androids with sword intent has been significantly improved, but the kendo talent is limited by the type of sword intent and seems a bit mixed. If you want to add specific kendo talents, further experiments are needed.

The compatibility between artificial people and Devil Fruits that has been added with the animal flesh and genes corresponding to the animal type Devil Fruit is even better. There are even many animal type Devil Fruit artificial people that have awakened after being "reborn" as devil fruits, and their strength has generally reached the level of a lieutenant general. .

This is indeed a good opportunity to improve the strength of the family.

It made Sparrow want to rebirth the animal devil fruit users in his family before he could be reborn himself.

But after thinking about it, it's actually not of much use to Sparrow.

The phantom beasts corresponding to the devil fruits of the animal type phantom beasts are difficult to find, and many of them are even extinct.

There are no phantom beast-type animal-type Devil Fruit awakeners. Generally, the possibility of animal-type Devil Fruit ability users reaching the general level is still relatively low.

There is really no shortage of ordinary Lieutenant General Sparrow, and ordinary animal-type fantasy beast devil fruit users have the strength of a lieutenant general.

Not to mention that using "evil medicine" and the like can also spawn a group of disposable lieutenant generals. Anyway, Sparrow's men have not been short of people since he awakened.

Lieutenant generals do not have absolutely overwhelming strength on the battlefield. For Sparrow, the current performance ratio of lieutenant generals is not that high.

Of course, it would be another matter if they could reach the general level.

But the top priority is that Sparrow himself needs to be reborn, and Sparrow cannot waste time.

Because rebirth comes as a baby, although this baby needs quotation marks. You can use pregnancy fruit to accelerate, but you need to consume part of your potential.

But Sparrow's rebirth is for higher potential, and naturally he will not consume his own potential for rapid growth.

So even if Sparrow has learned to return life, it will still take several years to grow.
