When the stone cutting masters from the Wanlong Gambling House were called out to witness the stone cutting, especially when it was that Wall Shield Turtle, they found it somewhat inconceivable. The Twin Soul Stone was already shattered, so how could there be any soul stone left to extract?
On the Wuji Continent, there are a multitude of demon beasts, which in turn gave rise to many special professions, with the Stone Cutting Master being one quite unique occupation.
Among these individuals, some were Hunter Soldiers in their earlier years, some were butchers; no matter their prior profession, they all possessed exceptional stone cutting skills. That's why they were recruited by the Wanlong Gambling House with high salaries.
When that Wall Shield Turtle was first brought to the gambling house, it was already identified as having a Twin Soul Stone within its body.
