A Love Letter from the World of Immortality

Du Shaomu, a rural boy, by chance, traveled to the parallel world of Dragon Territory with seven young ladies. Because he was overage, he could not enter the school for cultivating immortals, and he was living in another world without any relatives, so he had to exchange letters with the seven ladies to express their feelings. With no golden fingers and no upgrade items, in order to survive in a foreign country and to bring his seven wives and children back to his homeland, he relied on his intelligence and wisdom to make his way in a different world. In the end, the aliens from the Snow Kingdom attacked. In the battle to resist the aliens, could they return to their homeland intact?
