There is a particularly eye-catching building in the wealthy residential area of Jiangbei: there are two single-family, exactly the same five-storey luxury villas, there is a magnificent rockery in the middle of the two villas, there is an artificial waterfall flowing down on the rockery all the year round, and under the rockery is a large pool, which is planted with lotus flowers and raises various koi fish. There is a finely carved arched wooden bridge connected to the rooftop of the fifth floor of the two buildings above the rockery, because the magnificent posture of the two buildings will be reflected in the pool when the moon is full, the wooden arch bridge in the sky, the wooden arch bridge in the water reflect each other, so everyone gave these two villas a nice name called Shuangxi Building, this is the house of the famous rich brother in Jiangbei, Cai Chuan, the leader of the Earth Fire Gang, and his younger brother Cai Xiong, the two brothers have one building.

Cai Chuan and Cai Xiong were originally very poor, their father and grandfather were both workers in the Heilong Coal Mine in Jiangbei, because the son passed on his father's business, they should have been the third generation of coal miners, but Cai Chuan was inspired not to be a person like his grandfather and father since he was a child. When other people's children only know stupid Tao all day long, Xiao Cai Chuan is always holding a book and reading.

Cai's father often said to little Cai Chuan, "What do you see, can it be used as food or can it be used as money! You have to pay tuition fees to study! You also spend money to buy books! What a real loser! Cai's family is unlucky! Cai Chuan is on the stall!"

Cai's father didn't like Cai Chuan since he was a child, and always thought that he was an idle eater, but Cai Xiong was different. Although Cai Xiong is two years younger than Cai Chuan, he has been burly and sturdy since he was a child, just like the name "Xiong" given to him by Cai's father, he has brute strength and is big. Cai's father likes this son, and this coal digging job has finally been inherited!

Cai Xiong did not live up to Cai's father's expectations, he didn't like to study since he was a child, he had a headache when he read, he ate and slept all day long, slept and ate, and nourished his fat. Just fourteen years old is already like a young man, Cai's father proudly took him to the mine, although he was younger, but when a burly Cai Xiong stood in front of the foreman, the foreman did not say a word, and immediately agreed that Cai Xiong could go down the mine!

From then on, Cai Xiong could make money, receive food stamps, and eat more! But every time Cai Xiong saw Cai Xiong eating, he would give him his steamed buns with pity, watching Cai Xiong gobble up more than anyone else, Cai's father was full of proud smiles, and he said to everyone: "This is my son!"

In contrast, Cai Chuan's life is even more sad, Cai's father has a tense face every day, and scolds him for eating idle food, he said: As an elder brother, he should immediately drop out of school and go to the coal mine to make money.

Every now and then, Xiao Cai Chuan puts down his rice bowl, takes the book to the door without squeaking, and at night in order not to turn on the lights and not scold Cai's father, he reads in the moonlight, and has a high degree of myopia.

Cai Chuan was not liked by Cai's father, and he was originally very painful, he felt that he couldn't fight against his father, and he couldn't fight against the fate of his three generations of workers.

Cai's mother was not an ordinary woman, she used to be the eldest lady of the landlord's family, and since she was a child, she had a teacher who taught her the Four Books and the Five Classics, and later when she grew up, she was sent by her father to the women's school for further study. Originally may have cultivated a talented girl, but I didn't expect something to happen, his father was knocked down because of the long-term exploitation of the peasants' land, all the family property was confiscated, and she was also sent to the countryside of Jiangbei, and then her parents died, she herself was helpless in the countryside of Jiangbei, although she grew up well, but because she was the daughter of the landlord, no one dared to marry her!

Later, an incident happened, Grandpa Cai had a mining accident and died when he went to the mine to dig coal. Cai's father was in his thirties at that time, and he couldn't afford to buy a wife, so he had to grit his teeth and stomp his feet and reluctantly listened to Cai's grandmother's words: If you are not filial, you will be the greatest! Cai's mother was very competitive, and gave birth to two sons in three years, namely Cai Chuan and Cai Xiong. Although Cai Chuan has not been loved by his father since he was a child, Cai's mother has always favored him. Especially his read-alike appearance, which is the only light in Cai's mother's dark life. Cai's mother always tried her best to save a little from her small rations and secretly gave it to Cai Chuan. secretly saved some from the family's living expenses and paid Cai Chuan's tuition. Regardless of the four seasons, she picked up the scattered black briquettes on the ground everywhere, collected them to exchange for money, and secretly saved them.

When he was about to take the high school entrance examination, Cai Chuan had already succumbed painfully under Cai's father's poison, compromised, and vowed not to study anymore and to go to the mine to make money. It was the first time that Cai's mother, who had always been obedient to Cai's father, had a conflict with Cai's father, Cai's mother hit her head against the wall, and blood flowed everywhere, she just had to fight for her life and insist on letting Cai Chuan study. In the end, Cai's father was afraid that he would really make trouble, so he finally agreed. Cai Chuan, who was sixteen years old at the time, covered Cai's mother's gurgling blood with his hands, and swore fiercely that he must get ahead in this life and take his mother to live a good life!

Cai Chuan really inherited Cai's mother's reading genes, was admitted to Jiangbei University, and was admitted to the geological exploration major, perhaps this is what happened in the dark, and Cai Chuan's generation is destined to still deal with mines.

Cai's mother relied on the money from picking up briquettes for Cai Chuan to finish college, and Cai Chuan graduated from college and was assigned back to Cai's father's Heilong Coal Mine as the deputy mine manager; when Cai's father led Cai Xiong and a group of worker brothers to wait respectfully for the arrival of the new leader, he found that the person who got off the car was actually his unproductive son Cai Chuan, and he was dumbfounded! He didn't understand one thing until he died: How could a stupid son who couldn't even afford a briquette become a mine manager! God was so unfair to his precious son Cai Xiong, Cai Xiong is the one who can be entrusted with important tasks!

But if you don't understand, you don't understand, after all, there is an old saying since ancient times: brothers in war, father and son in battle. Now that Cai's father and son are gathered in Jiangbei Heilong Coal Mine, they will naturally have a earth-shaking action!
