Cain Scarlet's idea was also quite straightforward. As a Lord whose sleeves were clean, there were quite a few Sects and Family Clans within his city. As long as he returned and requested as a Lord, he believed these clans and sects would be willing to contribute. If each family were to give one million Spirit Stones, ten million Spirit Stones would not be a problem.
Actually, if there were ample time, he could simply mobilize the tens of millions of people in the city. Relying on his past prestige and image within the city, the ordinary people would definitely be willing to contribute, but it was a critical moment in dealing with the Demonic Sky Gate, and Cain Scarlet understood that there wasn't much time.
