At the critical moment, it was Feng Xing who found a colleague of his. That colleague's hometown was in the north-east, and eventually, they shipped a whopping ten bags of black earth all the way from there. The soil quality; just as it was poured out, instantly surpassed that of the mixed soil Zhuo Feng had surreptitiously dug from the flowerbeds downstairs.
At the end of August on a weekend night, the lights were rarely on in the old apartment building. Feng Xing set up a rack of bamboo right in the middle of the balcony, hanging a light bulb on top, which was powered by electricity pulled up from the lower floors. Additionally, a hallway light was installed along the corridor from the sixth floor to the rooftop.
To prevent water from seeping down to the lower floors, the area of the rooftop designated for cultivation was entirely covered with a layer of silver waterproof membrane, and then the soil was spread evenly on top.
