"Boss, should we continue?" The workers went a few steps backward and asked after they saw the weird smoke. They were all terrified due to they came from the countrysides without high education. That was why they were very superstitious. "Yes, continue, please!" Robert ordered calmly. He opened his ghost eyes. It couldn't be a coincidence with the smoke which came out of Bowman’s grave, even this was a rewarding task from the system. Soon he found out the wisp of blue smoke from Bowman's ancestral grave didn't change even he used his ghost eyes to check! What kind of smoke it was? It was so strange. He knew the Yin spirit should be black under the ghost eyes, so this blue one must be something different this time.
