One Piece: Emperor of the Four Seas

It turns out that the fork on the notebook is the volcano under the hot spring island. The hot spring island has always been on top of the volcano, so no one found it. As the hot spring island sank, the volcano also leaked out.

At this time, the volcano began to erupt without the suppression of the hot spring island. Then a large amount of water vapor filled the air, and then a circular rainbow appeared.

Everyone was fascinated by the beautiful scenery. This is a very rare sight every year and is called a gem on the sea.

Sayu said at this time: "Although I found the final answer, I still haven't figured out what it was that fell to the ground." Robin said with a smile at this time: "Don't you remember it's weird? The colors of the rainbow are upside down."

When Sayu heard this, he looked up and shouted in surprise: "I know, I finally know what the final equation is." Then he took out his notebook and started writing.

Lina was very happy to see that her sister finally found the answer, jumping around with the beaver cat.

At this moment, something started to rain from the sky. Thoreau caught the dropped thing and saw that it was actually candy. Candy was raining from the sky. It was really amazing.

At this time, everyone was eating the candies. Thoreau also took one and tasted it. It was very delicious, sweet and fragrant, and very delicious.

After the candy rain stopped and the circular rainbow disappeared, Solo, Luffy and others separated again. Solo's fleet carried Sayu and Lina and sailed towards the island where their home is not far away. .

It took less than half a day for the fleet to arrive at Sayu and Lina's island. It was very quiet and peaceful. The residents on the island made a living by fishing and were not wealthy. This also led to the lack of pirates. Come and visit this poor island.

Under the leadership of Sayu and Lina, Solo and others came to a house in the mountains. They looked at the dilapidated house. This was the home of the two sisters.

When everyone came to the room, Sayu invited them to sit down, then served tea, and then they couldn't wait to come to the laboratory, ready to start experimenting with the formula.

Everyone was waiting patiently and saw Sayu pour a lot of chemicals into a cup, and then the liquid inside turned into the color of a round rainbow.

Then I saw Sayu holding a bottle of liquid and slowly pouring it into the cup. Then the liquid inside the quilt shone brightly, and then the liquid inside disappeared, leaving only a round bead inside.

Sayu and Lina happily shouted: "Success, we succeeded." Then Sayu took out the jewelry in the cup, then came to Thoreau and said with a smile: "Brother Thoreau, look at the jewelry, we Successful"

Thoreau took a look at the jewelry and found that it was real. This was really amazing. Sayu and Lina's father really thought he was a powerful inventor.

Just as everyone was cheering, the door of the house was pushed open, and then an uncle with slovenly clothes and unshaven beard walked in. He looked like a savage.

When Sayu and Lina saw this man, they immediately shed tears, and then shouted happily: "Dad" and then rushed forward. It turned out that this man was Sayu and Lina's father.

Later, Sayou introduced Thoreau and others to their father, and Thoreau also learned that Sayou's father was called Gates and he was an inventor.
