Pirate: I broke Akainu's defense with a bucket of water.

Of course Nami was just talking.

"Mi! Go find Cheng Lang and ask him to come over and pry all this gold away!"

Mi immediately flapped her wings and flew away to find Cheng Lang.

Just as he took off, Chopper hurriedly came out from the side of the cave.

He had a grim expression.

"Chopper?"

"I saved the lives of fifty people, but I'm running out of medicine. I need to find Cheng Lang quickly. He has plenty of medicine."

Chopper's tone was heavy.

When they arrived here, Chopper smelled the smell of decay. He didn't pay attention at the time, but the closer he got, the more obvious the smell became. Finally, he followed the smell and found countless people lying in the cave, some of them were already dead.

Although some are still alive, they may be only one breath away from death.

If it were before he met Cheng Lang, Chopper might really have had to watch these people die.

After all, they have been here for too long, and what keeps them alive is their will, while their bodies have long been exhausted.

Without sufficient nutrition and blood replenishment, death may be waiting for them.

But with the help of MC's unreasonable blood-replenishing potion, everyone who was still alive was kept alive.

But he was just hanging there, after all, Chopper didn't have many potions.

The amount usually prepared is mostly for seven or eight people in case someone on the ship is injured.

The two left.

The rest of the Straw Hat Pirates naturally heard it as well.

They were all ready to help.

The golden ship and other things had long been forgotten.

At this moment, Cheng Lang was on Angel Island. He and Usopp were studying the special shellfish on the Sky Island.

Of course, Cheng Lang mostly converted them and threw them onto the conversion table to record them.

Fortunately, these Sky Island Shells will not lose their original functions after being MCized, but after being MCized, these shells will become durable props.

When the durability is used up, the shell will be directly damaged and disappear. Although it becomes a disposable item, its advantage is that it does not need to be stored.

Before using Sky Island Shells, they need to be stored inside it before they can be released.

Moreover, the storage amount of each type of shellfish is determined by its size.

However, the shells transformed by Cheng Lang are the size of a palm, but their effect is comparable to that of large shellfish.

It can be said to be very strong.

"So why did the Repelling Shell and the Wind-Spitting Shell become extinct?" Babai was puzzled.

He had already eaten the Repulse Shell and the Wind Spray Shell, and understood their logic. The Repulse Shell and the Shock Shell were essentially the same. The only difference was that the storage and release of the Repulse Shell were stronger than the Shock Shell.

Theoretically, under the condition of survival of the fittest, the impact shells should gradually die out.

After saying this, Babai spat out the impact shell.

Gan Fuer looked at the impact bei, who was not drooling, and he felt complicated at the moment: "It was deliberately erased because it was too strong."

Wapa also took back his own scorpion, but he didn't show any disgust or not. He just wrapped the scorpion around his hand with a bandage again.

"How to say?"

"In Sky Island's history, Repulsion Shells were originally more numerous than Impact Shells, even to the point of being rampant. However, Repulsion Shells were too powerful for most people to withstand. If their bodies weren't strong enough, the reaction force would shatter their arms. Similarly, after being used too many times, Repulsion Shells would shatter due to being unable to withstand the impact themselves."

"This shouldn't have anything to do with extinction, right?"

Chapter 247 Ark Proverbs

"Yes, but the Sky Islanders were afraid of us Shandians, so they chose to actively hunt and then artificially exterminate us. After all, we Shandians were crazy at the time. No matter whether we were men or women, young or old, we were all equipped with a swatting shell. Whether we were killed or our lives were threatened, we would use the swatting shells. With the mentality of one for one, we would not lose anything, which caused the Sky Islanders to suffer heavy losses."

Wappa calmly tells a small part of the four hundred years of struggle history.

Ganfor sighed, "This happened when you Shandians had just learned to use shells, about three hundred years ago."

"The Shandians are really... stubborn." Usopp couldn't help but complain.

Although he didn't know how powerful the repelling shell was, he had used the impact shell before. After all, Cheng Lang had deliberately instigated it and he was curious, so his arm was still numb at this moment.

Wappa said nothing.

"In other words, if I change the material of the shell, wouldn't it be possible to store and release energy infinitely?" Babai was a little excited.

He is very adept at changing the material of the Swallow-Swallow Fruit.

Moreover, the repelling shell is also a dead object. He feels that replacing the material is easier and less consuming than replacing the sword.

There were also some unusual movements in Wapa.

After all, Yaobai's Swallow Swallow Fruit demonstrated his abilities, and his ability to change nature had naturally been seen just now.

But after thinking about it, he waved his hand and said, "Forget it. Even if the material of the shell changes, I can't bear it many times."

Cheng Lang seemed to be thinking: "If the reaction force of the repulsion is very strong, if I put an impact shell behind the repulsion shell, can it absorb the reaction force of the repulsion shell and form energy?"

Usopp's mouth twitched: "Are you through the nesting doll?"

But he looked at Wapa and Ganfor curiously.

Both of them shook their heads at this.

"Both the impact and repulsion shells are not resistant to pressure, and if they are stacked straight together like this, the impact shells will break the repulsion shells first." Gan Fule explained with a smile.

Usopp seemed to be thinking about something.

The original method doesn’t work, but the advanced machinery does!

They cannot be stacked directly together, put a baffle in the middle and then connect them with a spring!

Usopp seemed to be possessed by Vegapunk, his mind suddenly opened up, and he began to write and draw on his draft paper.

And Babai also came over.

Then he exclaimed in amazement.

"Usopp, you are a genius."

"Hum~"

"Did you overlook one thing? How to trigger it? And...you two don't need it, right?" Cheng Lang directly poured a basin of cold water on them.

Are the impact shells and repelling shells very strong?

The former can only allow ordinary people to have the power to break walls, while the latter is indeed powerful, but compared to the strength of the explosive fruit and the iron golem itself, to be honest... it is completely unnecessary.

Especially the Explosion Fruit, as long as it reaches the F4 level, it will far exceed the Repulse Shell.

And Usopp can do it himself.

"Ah this..."

The two of them were immediately dejected.

Sometimes people are too strong, which actually hinders the burst of inspiration.

That is at this time.

Mi brought Chopper to the two of them.

After a brief explanation, Cheng Lang finally remembered what had happened and stood up to leave with the two of them.

As for Usopp and Yaobai, they looked at each other.

I chose to stay, after all, they couldn't help me if I went.

But Ganfor chose to stand up. In fact, he was also looking for those missing subordinates today, but no one had found them yet.

When Usopp saw Ganfor leave, he also stood up.

After all, with his current identity, he certainly can't walk around the streets openly, so what about chatting with Wappa?

Looking at the other party's cold and arrogant temperament, to be honest, Usopp still wanted to talk to Ganfor.

Moreover, Ganfor was once a god, and he was older and knew a lot.

This time, Mi couldn't bear it anymore.

It’s not that there are too many people, but simply that the eight hundred is too heavy.

The despised Babai felt helpless.

Finally, Cheng Lang and Gan Fule were taken away.

The three people left behind looked at each other.

The atmosphere was subtly awkward.

"Um...would you like to play an exciting game of Landlord?" Usopp tried to break the awkwardness.

And Wapa glanced at Usopp.

"Well...it's okay if you don't play..."

"How to play?"

Usopp looked at Wapa's serious expression and asked tentatively, "Never played it before?"

"Ah."

Then Usopp began to briefly introduce the rules of playing Landlord.

Soon the three of them started fighting.

……

On the other side, when Ganfor arrived at the place where Enel hid the giant ship.

He saw his former subordinates.

For a moment, no words could describe his inner emotions.

Cheng Lang directly threw splash recovery potions at them one by one.

Then he gave Chopper what he needed.

Recovery potions can replenish a person's condition, but just like milk cannot eliminate the weakness of being soaked in water, if the body is extremely weak or even on the verge of death, recovery potions can only keep one alive. After all, the upper limit of blood volume is gone, and no matter how powerful the recovery is, it will be useless.

Cheng Lang saw Chopper getting busy.

He no longer cared about this place.

Instead, he walked towards the golden ship outside.

This is the "spaceship" that Enel rides in the original work, a spaceship that can be powered by electricity.

To be honest, it looks like a ship, but its technological content seems to be higher than that of the manned space rockets on Earth.

After all, this thing can make a large amount of gold fly just by relying on electricity.

You know, gold is a 'heavy' metal.

If it were just comics and anime, there would be no need to consider physics, but since he traveled through time, physics aside, gravity still exists normally.

It can carry so much gold and fly, this must be a reaction engine, right?

Cheng Lang was naturally curious, but unfortunately he was not a scientist, let alone an old professor of science and technology dynamics. After seeing the countless gears and inexplicable water jars, he was completely confused.

He expected that most of the things here were rotating gears, but there should also be something like a core part, which is what supports it to fly, right?

But after wandering around for a long time...

Aside from the Yamato gear, there really isn't much else.

Moreover, these gears are linked together, and the ultimate goal seems to be just to make the outer gears turn.

You can't say...it just relies on those seemingly small gears to turn and then fly, right?

It doesn't make sense no matter how you look at it.
