I expected to see that everybody could eat fruits and vegetables again. That didn't really happen. A beginning of that is made at the end of the story, but you don't see that happen.

I also expected more people of the plant system beast department to appear near the end of the story. In the story it is hypothesized that people of the plant system department disappeared because they don't get enough vitamins because of the lack of fruit and vegetables. That didn't happen either. In the end the only ones from the plant system department are MC and his son.

MC lived on a planet that went through an apocalypse. He has a plant system that gives him more plants and more use of these plants when he gets gratitude of others. When he is about to get killed by a zombie his system transmigrates him into the body of someone with the same name on a different planet.

On this planet people usually get a beast sign before their 18th birthday. When they get that sign they can close a contract with beasts corresponding with their sign. People eat mostly flesh and almost no fruits, because a disaster struck the planet hundreds of years ago which changed the soil so fruits couldn't grow anymore. Special centers work on trying to remedy that, but they have only been able to grow little and few kinds of plants in their own centers. What they can grow is very expensive. People get their vitamins by buying nutritional drinks. There used to be people who got plant signs and could close contracts with plants, but they have not appeared for a long time.

The OG committed su*cide because he did not get a beast sign on his 18th birthday. The adoptive parents had died a few years before and grandparents did not care about him. When the grandparents evict him from his parents house after he leaves the hospital, MC moves in with ML whom he has met shortly before.

ML (Maine Cox) is the illegitimate son of a very prominent military family, but has never received any love or attention from them. All the friends he made were taken away by his halfbrother Julos. He is very distrustful of people because of the way his family treated him, but starts to trust MC.

MC finds out he is on a planet he read about in one of the books on earth. Maine Cox is the villain in this book. He decides to try and prevent ML from becoming a villain.

The male and female on the planet look almost the same. Female are usually smaller and have contracts with smaller beasts, but they look all male to MC.

MC gets a job at a beast treatment center and is loved very much by animals, because he has a feeling of nature on him. He gets his gratitude points from the owners of the beasts he helps. The energy of his system has been scattered and damaged when he transmigrated, so he has to build everything back up. The first plant he activates is a red pepper plant, which has supposed to have disappeared on this planet. He can use the plants to fight.

When people think MC has a plant they are delighted about this.

He has to find back the energy of his system or he will die. The first part (fire) he finds on the planet he lives in in the forest. It is guarded by several powerful A-grade beasts. They have become more powerful because of the energy, but it has also affected their minds. MC gets the energy back with help from the beasts (they also realise it affects them in a negative way). MC can talk to the anima.s affected by the energy. The beasts go back with him because they need to get away from the forrest for a while to restore their minds.

As the beasts get bored and want to help MC get money they decide to start a livestream which becomes very succesful. They do all kinds of acts in the livestream. They start to earn money very fast, because people hardly get to see such powerful animals.

ML has planted listening devices with Soria, Julos' mother to keep track of what they do and prevent them from hurting him or MC. The halfbrother has tried to force MC before to become his, which ML prevented. During the fight Julos finds out that ML has an S-class beast sign. When ML finds out that Julos wants to harm them again, he lures Julos out into the woods and kills him. He convinces the police he did not commit this mu*der.

When the system gets more energy he finds out the second part of energy (gold) is on a planet pretty nearby. MC and ML decide to travel to this planet. They find the energy which is guarded by a dragon who loves gold and glitter and MC gets this energy back. The dragon and a few other animals decide to travel back with MC. The dragon signs a contract with one of MC's friends.

Soria is convinced that ML killed her son and threatens MC. MC is then kidnapped by others. One of the beasts, the eagle, sees MC being taken away and follows them and prevents them from escaping. ML, who has put a tracker on MC (with his knowledge), captures them. The kidnappers and mother are convicted and Soria is sent to a prison planet with mentally ill prisoners.

The system finds the 3rd piece of energy (wood) on another planet and MC and his friends travel there. The energy has been taken by a large sunflower and MC's beast sign which is a sunflower appears. MC closes a contract with the sunflower. ML closes a contract with the flying lion attacking it.

Right after that system finds the 4th piece (earth) on a water planet nearby and they travel there. The 4th piece has been attached to a pearl inside a clam and the pearl and clam have become huge because of that. They have been captured and are about to be auctioned of. MC and ML decide to steal the clam and the 2 captured beasts with it. They succeed in stealing it and escaping, but the mermaid prince of this planet knows they did it. When MC takes back the 4th piece of energy he fnds out the 5th piece of energy (water) is also there. It has been scattered in the water. He takes this back as well but a fifth of the water energy is still missing.

ML gets more and more plants thanks to the system and asks someone to pretend to find seeds of some of these plants so they can be planted in an open way. The archeologist he asks finds a hidden military base while going out in which they experiment on beasts, which is forbidden. The eagle helps him escape but is shot with a particle gun. The eagle manages to fly back to MC while wounded. He tells them about the base and ML organises a rescue mission to that base.

In that base they find beasts who have serious mental issues because of the experiments that have been done to them, but MC can calm them down with his energy. He moves them back to his home. Surgeons operate them to get them back to normal.

ML's father is found out to be behind these experiments and is convicted and also sent to the prison planet. ML's grandfather turns in his resignation as general in the army.

When a delegation comes to talk about distributing some new plants to other cities, one person in this delegation turns out to be carrying the last part of water energy in a necklace. This person acts very irritated about everything and is also affected by the energy. MC steals the energy back with the help from ML, so now he has all his energy back.

Now that he has all his energy back, MC decides to tell ML all about himself. ML is very understanding.

During this time several people have closed contracts with the animals that live with MC. Only a few animals still live with MC.

MC gets pregnant and has a baby, who also has a plant sign. The baby can also understand the animals.

In the extra's we find out that the wolf who has closed a contract manages to turn into a male.

Later Tuan Tuan, a bird who has followd MC almost from the beginning, also turns into a human and goes to school with MC's son.
