At the beginning of One Piece, you get the Phantom Beast Devil Fruit

Carr carried Blackbeard and returned to Tiger God Island at night.

At this time, the burnt black beard had been handed over to Rena.

Rena is doing various examinations and experiments on Blackbeard.

Daphne immediately came to the underground laboratory in the forest after knowing that Karl had returned.

"Husband, how are you? Nothing unexpected happened, right?"

Daphne asked Karl worriedly after arriving at the laboratory.

"Don't worry, I'm fine."

"Blackbeard is not that strong without the Dark Fruit."

"But his physical skills are pretty good. No wonder he can leave scars on Shanks' face."

Karl said warmly to Daphne.

"That's good. I've always heard that this guy is very evil. Did Reina find out anything?"

Daphne breathed a sigh of relief when she heard Karl say it was okay.

"The results haven't come out yet, but the theory of three hearts can be ruled out."

"I've checked my knowledge, and Blackbeard only has one heart."

"If you say you can eat as many Devil Fruits as there are hearts, then Octopus Hachi can eat eight. So this statement is wrong."

"As for the reason why he can eat multiple Devil Fruits, I think it may be the reason for the Dark Fruit."

"Since the Dark Fruit can attract the power of demons, maybe those with Dark Fruit abilities have a dark space to store the power of demons."

"This way, you can release it directly when you need to use it. However, there should be a limit to the stored Devil Fruit power. It is estimated that it cannot exceed three."

Karl thought for a while and expressed his inference.

"Is that so?" Daphne also became thoughtful after hearing this.

"Master Carl, Master Daphne!" Rena came over at this time.

"How is it? Rena, is there anything special about this person?" Daphne asked immediately.

"There's nothing special about his body structure, but his brain is weird."

"I can tell from the reaction measured by his brain waves that he actually has multiple independent personalities."

"This is the first time I've met such a person!"

Rena was a little surprised. It was unheard of for one person to have several sober personalities.

"It seems that my guess is good. Blackbeard's ability to possess multiple Devil Fruits has nothing to do with his body. It should be the Dark Fruit."

"Otherwise he wouldn't have endured it for so long on Whitebeard's ship, but now he actually chooses to swallow the fruit, which is a bit strange."

Karl took out the Tuntun fruit and looked at it carefully.

"Tuntun Fruit? Wasn't it eaten by Valpo? Why is it here, Karl?" Daphne was a little shocked.

"Blackbeard killed Valpo, and the Tuntun Fruit reappeared on Drum Island."

"It is probably a unique setting of some Devil Fruits that can only appear on the island where it was born."

"Just like Alabasta, those two Devil Fruits will appear in that country for generations."

"And Blackbeard was Whitebeard's ship on Cigu Island from the beginning, so he should have chosen to swallow the fruit because he knew more specific information about the Tuntun Fruit."

Karl said after thinking for a moment.

It’s just that my wish to eat multiple Devil Fruits was shattered.

"Husband, what are you going to do with this Tuntun fruit?"

"Since Blackbeard spent so much effort to return to Drum Island from the New World just because he wanted to get the Tuntun Fruit, then this Tuntun Fruit should be somewhat special."

Daphne took the Tuntun fruit in Karl's hand and looked at it.

Carl also thought seriously after hearing Daphne's words. He was a little confused about what purpose the Tunton Fruit had besides being able to create that kind of memory alloy.

Could the Tuntun Fruit really be able to swallow all things?

correct! Devour and strip away!

"Daphne, do you think it is possible for the Tunton Fruit to strip away the demonic power of a person with abilities?"

"Why else would Blackbeard go to such great lengths to get the Tun Tun Fruit?"

"His purpose from the beginning was very clear, which was to build a team with all Devil Fruit members."

"Since there is no hope for the Dark Fruit, then Tun Tun Fruit is his second choice!"

"It's just that the Tunton Fruit is not as powerful as the Dark Fruit!"

Carl had an idea, and he thought this might be the reason why Blackbeard took the Tuntun Fruit!

Daphne's eyes lit up after hearing what Karl said!

It's very possible!

In the comics, the first thing Blackbeard did after getting the Dark Fruit was to attack Drum Island, but Valpo escaped.

"Rena, how about giving you this devil fruit?" Daphne looked at Rena.

Rena is a technician, she knows how to synthesize various materials, and giving her the Tuntun fruit will better reflect the value!

"Hey? Shall I eat?" Rena was a little surprised.

"Yes! This Tuntun fruit can swallow all kinds of things, and it can also synthesize various materials according to the characteristics of the swallowed things."

"You are a technician, you should know the value of being able to synthesize various materials, right?"

After Daphne finished speaking, she handed the Tuntun Fruit to Rena.

"Synthesize various materials?" Reina looked at Tuntun Fruit with shocked eyes.

Karl also understood what Daphne was thinking. It would be a good choice to eat the Tuntun fruit for Rena. She could be trusted, she was a scientist, and she knew how to use this fruit.

"I understand, thank you Lord Carl and Lord Daphne!"

After thinking for a moment, Reina understood the value of this devil fruit, and then bit it down.

Just after eating the Tunton fruit, Rena's small body suddenly became a lot fatter!

"Huh? Why has my body changed?" Reina looked at her bloated appearance in surprise.

"Rena, can you try to control your body shape?" Karl said suddenly.

"It seems okay! My belly has become a small factory now!" After finishing speaking, Rena contracted her belly and her body gradually shrank.

"Very well, Rena, you should make good use of this Devil Fruit from now on!"

"I'll find some esper people later and let you try to see if you can strip away the devil's power from the esper people." Karl said to Rena.

"I understand, Master Karl, I will develop the Tunton Fruit and awaken it as soon as possible!" Rena said seriously.

The next thing Karl considered was to capture some ability users to test them out.

If it can really be peeled off, then they can have many powerful devil fruits without waiting to find the dark fruit!

"Let's go, wife, I'm starving after flying all day. Let's go to the food city to eat something!" Karl turned to look at Daphne and took her hand.

"Yeah! Lucille is also in the Food City now. She was chatting with Yixiao when I came over."

"It seems like Lucille quite likes playing with this uncle Yixiao."

Daphne said with a smile, and then walked out of the underground laboratory with Karl.

"Then have you told Yixiao about the satellite? Don't let him summon meteorites to hit our satellite." Karl suddenly remembered and said.

"Don't worry, I've already told him. Yixiao was a little surprised when he found out why we were looking for him, and even joked that he saved a life."
