A few days later, the World Tunnels leading to Qing Xin City and Liu Shi City were established one after another.
This meant that, from this moment onward, people could travel directly from the small town in the southern suburbs of Tian Yuan City to three famous large cities within Tai Xuan Territory.
Of the three cities, Qing Xin City was the most magnificent. Its permanent population exceeded three million, and all kinds of industries were highly developed. It possessed many advanced industries, such as Forging Factories, Scroll Production Factories, Enchantment Factories, and Pharmaceutical Factories.
From now on, purchasing Common Star goods for Tian Yuan City would be extremely easy.
The transportation cost was practically negligible.
Moreover, whether it was Cold Moon City, Liu Shi City, or Qing Xin City, all three were located in the core region of Tai Xuan Territory, and all had train routes leading directly to the major cities of the surrounding areas.
Starting from these three cities, one could reach most cities in the territory within three days.
The World Tunnel Alliance had taken shape!
The impoverished Cold Moon City Lord was the most concerned. "How safe is the tunnel? How many travelers can it carry simultaneously at most?"
She naturally understood the stability of the tunnel space. However, once the World Tunnel was opened to all of Tai Xuan and every passerby, no one could tell whether among them there might be lunatics, spies, or suicide warriors from enemy forces.
If the Space Tunnel came under attack, would it become unstable, causing the tunnel to collapse and spatial turbulence to descend?
"That's a good question."
Mu Yuan said, "We can conduct an impact test, but I can say with certainty that the entire Serpent Path, including the stable space around it, won't be easy
