. . .
[Chapter: 1-10]
-A guy from our world gets transported to the world of Dragon Ball into the body of Master Shen, who was a fellow disciple of Master Roshi when they both trained under Master Mutaito.
-The story begins many years before Goku is sent to Earth. In the first chapter, he awakens while in the midst of training his disciples.
-The transmigrator finds that his personality has merged with that of Master Shen.
-For the first six months, he just improves his strength with weight training and other such methods..
-Afterwards, when Master Shen's brother returns to the school, Shen leaves the school in search of the underwater treasure that Goku finds in the OG Dragon Ball series.
-After secretly stealing the map from Master Roshi, he takes all the treasure, even getting his hands on an antique robot that was guarding the cave.
-Then, wanting to change the underwater cave where the treasure was hidden into a solid base, he goes in search of a good scientist.
-He invests some of his wealth in Dr. Brief's company: Capsule Corporation.. From him, Shen learns about a scientist named Dr. Flappe who lives in some snowy mountains..
-After recruiting the scientist, Shen goes to meet Goku's grandpa: Gohan. After a fight, they both go to climb Korin Tower.
-Sending off Gohan with a Hoi-poi capsule car, Shen remains at the base to take in a disciple.. Bora is the son of a tribal chief who lives in the forest at the base of the tower.
-Just the next day, he recruits two new disciples; one is Nam and the other is Giran (A/N-Search up their names).
-He takes the three disciples and Dr. Flappe to the cave. Flappe starts working on fixing the guardian robot..
[Chapter: 11-22]
-He trains Nam, Giran, and Bora.
-He collects the Dragon Balls with the radar that Flappe made and makes a request to Shenron to turn his old body to its prime, getting a youthful body as a result.
-Then Shen and Gohan go to the Lookout above Korin Tower. There, the two train under Kami and Mr. Popo for 3 years.
-Afterwards, returning to the cave, Shen takes his disciples to the old Crane School.
-In the school, finding out about the tyranny his brother Tao Pai Pai has caused, Shen nearly kills the man, but later opts to just turn him into a brainwashed cyborg, looking like Iron Man.
-Afterwards, he has his disciples participate in the 18th Tenkaichi Budokai.. In the competition.. Giran uses magic he got from Kami. Bora uses his speed and Ki-ko-ho technique, and Nam uses a ki projection technique that looks like a Buddha.
[Chapter: 23-30]
-Shen takes Dr. Flappe back to the snowy mountains to let the guy meet his parents.. There, at Jingle Village, he learns of the Red Ribbon Army's evil deeds..
-Shen goes to the RRA's HQ and crushes them. He also rescues Launch and Android 7, along with the son of Dr. Gero; Gevo, from the prison.
-Additionally, he takes three of the child trainees in the army; Violet, Red, and Silver, as disciples.
-He finds Tien Shinhan. He also sends Launch to train under Roshi's elder sister: Uranai Baba.
-The space pirate, a Saiyan named Turles and his crew, invade Earth.. They want to plant a Tree of Might on Earth that will suck the planet's life force to create fruits that grant its consumer immense power.
[Chapter 31-40]
-Approximate power levels till this point;
Turles - 15,000.
Shen - 9,000.
Giran, Nam, and Bora - around 2,000
-After defeating the aliens with extreme difficulty (Ch: 30-33), life goes back to normal.. Bora marries a girl from his tribe.
-Shen, wanting to improve his skills, decides to go to the Other World and train under King Kai.
-To go to the Other World, one has to die. He couldn't do that, obviously, so he goes to meet Ms. Annin in the Furnace of Eight Divisions.
-Annin helps him traverse dimensions, and so he arrives in the Other World. There, he trains under King Kai.
-Meanwhile, on Earth, Launch also comes back to the underwater base..
-In Shen's absence, his disciples are busy fulfilling the orders he gave before leaving. They create a structure called Dragon Tower where martial artists can come to gauge their strength and grow stronger. (Chappa; someone who lost to Nam in the past, is among those attempting to climb it)
-Dr. Gero and his son Gevo make an appearance again. Gero agrees to reconnect with his wife on his son's request..
-Shen decides to go to space, so he takes the help of Dr. Brief to build a spaceship, referencing the ship that Kami came to Earth in as a base.
-On their way to Planet Namek, they face a trio of bandits, who are swiftly defeated, and their ship is captured.
[Chapter: 41-50]
-Arriving at Namek, the two; Shen and Launch; have their potential unlocked by the Namekian Elder: Guru.
-The whole time, on Earth, the disciples are also busy.. In the area of the ocean near the underwater hideout, they create an artificial island and erect a pagoda, properly establishing a new Crane School for the world to see.
-On the other hand, Shen and Launch leave Planet Namek and head to Planet Cereal, where the Cerealians, alongside a small group of Namekians, lived.
-Rather than directly telling the Cerealians about their impending doom at the hands of Saiyans and Frieza, Shen first informs the wise Namekians.
-The events jump to the Saiyans coming to Planet Cereal but finding nobody on the planet.. Bardock and his team are also among the invading forces.
-Lately, Bardock has been having a bad feeling, and it turns out his fear isn't unfounded, as Frieza kills all the Saiyans and destroys Planet Vegeta with them. Still, Bardock's son Kakarot manages to survive as he is sent away before the destruction occurs.
-Meanwhile, on an unknown planet, the inhabitants of Planet Cereal who survived against the odds have started new lives. They used the Dragon Balls to accomplish this.
-Further, using the Dragon Balls, Shen revives some of the Saiyans, but only those who could change their mindset and become peaceful/good..
-However, the main man Bardock is missing, not because he didn't have the potential to turn over a new leaf, but because of something unexplainable.
-Notable people who are revived are Gine and Bardock's four comrades; Fasha, Leek, Taiga (Tora), and Taro.
-At the same time, upgrades are made to the Dragon Tower on Earth, and Kakarot's spacecraft has also crash-landed near Son Gohan's house.. Gohan decides to adopt the child, naming him Son Goku.
-After returning to Earth, the pair go to space again, this time in an upgraded spaceship.
-Their ship heads to the Galactic Patrol's headquarters.. There, they meet Jaco, a space patrolman who is a friend of Dr. Brief's older daughter; Tights.
-Through Jaco's recommendation, Shen gets to have a discussion with the leader of the Galactic Patrol.
-The Galactic King measures Shen's power, and it's over 500,000. Thus, the two parties settle on a deal. Shen agrees to join the Galactic Patrol and will also help recruit the remaining Saiyans, Cerealians, and strong Earthlings, while the Patrol will provide him and the Crane School with more advanced technologies and other support.
