Next came...
The return journey.
There were roughly fourteen days left before departure. The Mortal Domain arranged rooms at an inn in Mortal City for Qian Jue and Green Edge, while Chen Fan got busy. He would spend those fourteen days putting the resources accumulated over this period to use.
First up...
The City Wall.
Many of the Mortal Domain's buildings had reached Level 70 when it advanced to a seventh-level continent. The City Wall was the exception; it was still only level 40.
Mainly because upgrading the City Wall consumed far too much and took considerable time.
His main task during this period was to upgrade the City Wall.
"Phew..."
Chen Fan exhaled softly, drained the strong tea in his cup, and got to work!
Sitting on Xuan Ba's back, Chen Fan traveled along the Eternal Night Defense Line, upgrading as he skirted its edges like an old Beijinger sipping porridge around the rim of a bowl. Bursts of white light flashed up in rapid succession, and the City Wall's level kept rising.
Previously, he had spent 8.91 quadrillion eerie stones raising the Eternal Night Continent's City Wall to level 40. That was an astronomical figure, and each subsequent upgrade demanded even more eerie stones.
Still...
Fortunately, he had found the gift Hades left in Abandoned World 999: an astronomical fortune in eerie stones. It had provided him with an enormous supply.
Ten days later.
The Eternal Night Continent's City Wall had been completely transformed.
Its height and width had barely changed, but its solid, rammed-earth weightiness gave anyone who looked at it an overwhelming sense of security.
Upgrading to Level 50 consumed 17.89 quadrillion eerie stones.
Upgrading to Level 60 consumed 47.82 quadrillion eerie stones.
Upgrading to Level 70 consumed 78.99 quadrillion eerie stones.
Upgrading to level 80
