"Dr. Stone" Chapter 221 may finally reveal how Senku and his science crew's epic adventures will play out. The trip to the moon continues and they will soon land their feet on the satellite after all the commotions and disturbances.

Of course, landing on the moon means they can finally face Why-Man. So, will fans see the mysterious and powerful radio wave in "Dr. Stone" Chapter 221?

Senku and his team have come a long way to make their moon mission happen. This event brings them closer to understanding more the purpose of Why-Man's actions, Epic Dope noted.

So, what will be the next challenge they are about to face as they continue their space travel? Ryusui now thinks there is a better pilot than him and it is Stanley, Epic Dope noted.

He believes he is more suitable for handling the spacecraft, but it remains to be seen if everyone agrees with him. There are theories Senku may also get replaced after Tsukasa recommends Kohaku.

Sure, the manga is showing quick progress with how its chapters are flowing, but fans want to see the development in their mission. The series is getting more exciting now that the science crew is on their way to discovering Why-Man's whereabouts.

Meanwhile, in "Dr. Stone" Chapter 220, Gen wanted Ryusui to get excited about their moon mission. Sai joined the team to tell what Ryusiu did when they were just kids, per OtakuKart News.

He loved to build ships back then and even promised Sai that he would set sail one day. As Sai was busy doing math and science then, Ryusui would dream of new adventures that he was about to do.

He started to build his own ship and asked Sai for help with some science stuff about his vessel. Back to the present time, Sai showed everyone the flight simulator for the rocket that made him remember that Ryusuis asked him to build one for his ship in the past.

The crew started to celebrate after seeing Ryusui's work. They, then, started a game and Ryusui beat the high score.

This made Taiju impressed, while Ryusui revealed he used to be the sim game champ. He, then, talked about science and their trip to the moon.

This made the crew realize no one could match Ryusui when it came to being a pilot. Ukyo admitted Ryusui was the best, saying he was the stone world experienced pilot.

However, Ryusui would eventually realize someone was better than him. Fans are about to see this and more when "Dr. Stone" Chapter 221 drops on Sunday, Dec. 5.
