Several days later, the World Tunnels leading to Qingxin City and Liushi City were successively established.
This meant that from that moment on, from the small southern suburbs of Tianyuan City, one could directly reach three very famous large cities within the Taixuan Realm.
Among these three cities, Qingxin City was the most majestic, with a permanent population exceeding three million and a highly developed variety of industries, including forging factories, scroll-making factories, enchantment factories, and pharmaceutical-making factories among its high-end industries.
It had become very easy for Tianyuan City to purchase ordinary goods afterwards.
The transportation cost was virtually nil.
Moreover, whether it was Han Yue City, Liushi City, or Qingxin City, they were all located in the more central areas of the Great Domain—Taixuan Territory, with direct train routes to the major cities of the region.
