Transmigrating to the Siheyuan: A Wonderful Life

Zhang Hao's soul transmigrates seventy years into the past, into another world of courtyard houses. After unexpectedly getting together with Qin Huairu, he plans to rely on the System's support so they can build a good life together. But all sorts of temptations keep appearing around him. He can hold fast to his principles, but the foolish woman at home insists on tearing down their defenses herself and inviting trouble in.

Luckily, the System comes through, or he really wouldn't be able to support such a big family.
