Li Chaoyang, a top student in science and engineering, traveled back in time to the 1960s and became the orphan of an anti-special hero in a steel rolling mill. When he opened his eyes, he was in a desperate situation. The real estate savings left by his uncle were usurped by the "beasts" in the courtyard. The original owner was even plotted against, and his life was hanging by a thread. Thanks to Lou Xiao'e's rescue, he relied on modern thinking and historical foresight, and with legal certificates in hand, made a strong return under the witness of the sub-district office and the police. He ripped apart Jia Zhang's arrogance, exposed Yi Zhonghai's moral kidnapping, and confronted Silly Zhu's unreasonableness. He even accidentally activated the live broadcast system and spread the famous "animal abuse" scene in the courtyard to modern times.
On the one hand, he wants to take revenge and rectify the monsters in the courtyard; on the other hand, he cares about his family and country, and relies on the system to build a bridge connecting the two parallel dragon kingdoms. From the technological breakthrough in the steel rolling mill to the spark of a prairie fire in the secret scientific research institute, from the small land of the courtyard to the vast journey of the stars and the sea. Personal grievances and hatreds eventually merged into the rolling torrent of the country's rise. Because of him, the two dragon kingdoms joined hands to break through the shackles of history and soar towards a new era of civilization!
