It was said that the underground difference engine network array of this largest human library was driven by geothermal energy. It was available around the clock. The entire library included a lot of information entry clerks and maintenance engineers, who maintained the normal operation of this huge difference engine system. As this difference engine system ran normally when the trouble-reappearance situation came into being, Zhang Tie could normally use this system even though he was alone in the library.
With the trouble-reappearance fruits that Zhang Tie used in Xuanyuan Hill, besides killing Han Zhengfang and Han Yuanhong, he also gained the largest legacy, this huge database in Xuanyuan Hill...
The largest human library and database became Zhang Tie's private study at this moment.
Besides this library, the database in the headquarters of those major human trade unions in Xuanyuan Hill was also open to Zhang Tie completely.
