In the end, Li Du decided to accept Aubrey and the other men.
Since he had come to Lightning Ridge, the mining was mainly done by Godzilla and Brother Wolf. Godzilla was fine, but Brother Wolf was his bodyguard, so mining was not suitable for him.
Of course, Li Du paid them a huge salary, and Brother Wolf enjoyed the work. However, Li Du himself could not enjoy it. He also participated in mining activities, but he was very tired. If someone could work for him, then he would be free to do other things instead of mining.
As for his secret? This problem was easy to solve. He could arrange for Aubrey and the others to carry out the initial excavation of the mine, and when it came to the gems, Godzilla and Brother Wolf could take over.
