Seeing the response of the Earth Crystal Spider, Xu Fan nodded his head. Only obedient demons were good demons.
The Five Spirit Monkey swaggered out of the Fire Ant nest and returned to the underground base.
At this time, nearly half of the space in the underground base had been transformed into a rune cannonball production line.
"There's no difference between this cannonball and free stuff, it just consumes a bit of Spirit Iron and Spiritual Qi."
After the first Deputy Cannon Level Rune Cannonball was produced, Xu Fan no longer felt heartache for using them. He even specifically produced satellite versions of the Sky-based Weapon in the later stages.
"Haha, including the consumption of spiritual power, a deputy cannon level shell costs less than 500 Spirit Stones. It's cheap."
Xu Fan imagined himself waving his hand and unleashing thousands of cannon shots at once.
