Chen Ruoyu worked there for fourteen years after studying in Japan. He studied civil engineering and construction and also engaged in related work after graduation. He usually likes to read some novels, and recently became obsessed with doomsday survival series. So when he finally saved enough money to buy his own land on the outskirts of Hokkaido, he used his expertise to design his own house. It not only had a high foundation, but also had a two-story basement, making it the perfect doomsday fortress in his mind. The year after the house was completed, Japan experienced an extremely rare and abnormal blizzard and extremely cold weather, which lasted for more than 60 days with no intention of stopping. Sea levels in coastal areas rose and seawater poured in. There were countless casualties and countless people were displaced. But Chen Ruoyu stayed in his doomsday fortress and had no worries about food and drink. But you can't expose your food and shelter. It's safest to keep others unaware of your little house. Later, he met Xie Heng, a mechanical engineer who was also Chinese, and helped him upgrade the fortress and fight side by side. Time and time again, they repelled the local Japanese who wanted to occupy their fort. Went out several times to replenish supplies. A year later a government-organized shelter was established in Hokkaido. But Chen Ruoyu and Xie Heng did not go. Instead, they waited for another six months to wait until the way back to China was clear, and then returned to China.
