Has anyone introduced the plot of Bi's trajectory and Zero's trajectory in detail, and made it clear?

Zero trajectory: the protagonist is assigned to the newly established government department (urban management) after graduation. The main job is to solve the citizen's entrustment (to compete with the guerrillas for business). There are only five people in this department, Zhou Ke Johnson, the mayor's granddaughter, a talented Lori, a handsome red-haired boss and a minister. At first, it ended in civil entrustment and civil disputes. Later, with the escalation of the entrustment, it experienced the God Wolf incident, the assassination of the mayor, the underground auction (in order to get a daughter) and the drug incident. Finally, I found out that it turned out to be Bi Biao: there are two new people in the leading role department, the short-haired girl and Cowherd Waji. At first, they also solved some minor problems. Later, Eat Your Own Snake and Red Constellation (Randy's father's mercenary group) also went to Crossburg to join in the fun. At the Lanta Conference, Mayor Dita declared independence (originally a dependency of the Empire and the United States), which led to the national war. As a result, the mayor directly bought three Gundam at a large price, killing the empire and the national army. At the same time, he also exposed the true face of the big boss, stole the protagonist's daughter, and forced the protagonist to dismantle Gundam with his bare hands. Originally, the mayor felt that the victory was in the bag, and the mayor's daughter cheated at this time. The ghost of joint war, the swordsman of the wind, the lawyer selling his father, awakens the treasure of zero. Finally, the protagonist defeated the war ghost, juvenile delinquent, blade master, mayor's daughter and treasure, and got her daughter back!

Protagonist: No legendary life experience. One of my brothers died unexpectedly (for unknown reasons, it was later discovered that the murderer was Feng Zhi's lawyer and blade master).

Big miss: the mayor's granddaughter, there is no special secret about beauty.

Genius Lori: I am proficient in computers. When I was a child, I was abducted by an organization and gained a genius mind by doing human experiments (this organization once destroyed the country and saved Ling).

Handsome red-haired boy: Daddy, nicknamed Red Death, is the head of the strongest mercenary group (killed in battle). At present, it is taken care of by my uncle's war ghost. He accidentally involved his relatives and friends in the battle and left the mercenary group.

Niulang Waji: It's really the holy book of order in the No.9 Star Cup. It's awesome.

Silver: The legendary assassin (who lived for a hundred years, but actually passed down from generation to generation) is Ji Lixia, the dance of the moon.

Seven sisters: the seventh apostle of the snake that eats the body, a steel saint, and a founding father who fought side by side with the imperial emperor (more than 200 years ago). It is said that the snake that eats the corpse has the strongest fighting power, the extreme force and the rational state.

Minister: It seems lazy, but it is always very powerful at the critical moment. I used to be the boss of the blade master and the eldest brother of the protagonist (I am sorry for the death of the eldest brother of the protagonist).
