Round Trip to 70: Becoming the Richest Man from the Prodigal Son's Return

Zhang Yang died suddenly after staying up late and working overtime. Then he opened his eyes and found that he had traveled to the 1970s! Not only did he become a famous second-rate son from all over the country, he also beat his beautiful wife with bruises all over her body. Just when he was worried about his family, he pushed open the backyard door... Damn it! It's actually connected to a modern rental house? ! As a result, Zhang Yang embarked on a crazy road of dimensionality reduction to defeat him. Modern cheap bulk rice → seventies black market hard currency! Profit +1000%! Sugar costs two yuan in modern times → a popular high-end product in the 1970s! Profit +5000%! A century-old wild ginseng from the 1970s → a sky-high price treasure in a modern auction house! Wealth surges! "Zhang Yang, where did you get so much money and polished rice?" The captain was so shocked that his eyes almost fell out. Zhang Yang (takes a deep breath at the front door): "I picked it up, do you believe it?" From a scumbag with nothing to a giant of the era with countless supplies. In that era of lack of food and clothing, Zhang Yang relied on a door and completely won!
