"The Oasis Passage was completed six years ago, a year later than my niece originally planned for the fifteen-year deadline, because we encountered an exceptionally large sandstorm one year, which partially destroyed three previously constructed oases. We had to halt work for a year to repair the damaged oases."
"At the same time, due to the impact of that sandstorm, after the completion of the Oasis Passage, my brother convened our elder council and decided to form a thirty-person Oasis Maintenance Team. The members consist entirely of clan cultivators and guest elders, with each receiving an additional fifty clan contribution points annually as a subsidy."
"This Oasis Maintenance Team is usually stationed at those twenty-five artificial oases, slowly expanding the size of the oasis each year in groups of three. If they encounter a large sandstorm that destroys the oasis, they will receive family orders to gather together to repair the damaged oases."
