The recruitment information from Myriad Snake City's Territory's Heart indicated that the weakest creature available was a mere poisonous snake, which could be recruited for 10 gold and 1 sulphur each.
The strongest, however, was a terrifying creature known as the Dark Serpent Dragon, rumored to possess the bloodline of giant dragons.
To recruit one, not only did it cost a large amount of gold, sulphur, crystal, mercury, and Dark Souls, but also a Sub-Dragon Dragon Crystal!
A single Sub-Dragon Dragon Crystal could only recruit one Dark Serpent Dragon, which spoke volumes about the creature's frightening nature.
After considering the resources and materials he currently possessed, Shen Nanfeng used up all of these materials in one go and recruited a large number of Monster Beasts.
"Not enough! Still not enough! A large amount of materials must be sent over before more Serpent Demon soldiers can be recruited!"
"Boom!"
