Siheyuan: I Enjoy the Double Doors in Zhongguyuan

When Zhou Feng traveled to the world of Siheyuan, he did not have invincible martial arts in his hands. He only had a double door that could be opened once a day and could only carry ten cubic meters of supplies at first. He first exchanged modern food for the old furniture that was regarded as tattered, and then brought the antiques back to modern times for cash, relying on the time difference to make life in both worlds improve at the same time. The Jia family wanted to get supplies for free, Yi Zhonghai wanted to use hospital rules to restrain them, and Xu Damao and Shazhu kept causing trouble, but instead contributed a lot of emotional value to the double door to upgrade. As the capacity skyrocketed from ten cubic meters, what Zhou Feng could take away was no longer just a few bags of grain, but a complete set of production equipment. After his identity is revealed, both modern experts and organizations from another era begin working with him. While others were still fighting for a meal in the courtyard, he was already thinking about how to move a power station to allow the industrialization of another world to take off early.
