Before Lu Ming started to recruit people, he selected a group of experts to cultivate under the statue of the primordial god.
As soon as these experts started cultivating, they were shocked by the effects of the primordial god statue. After they finished cultivating, the news about the primordial god statue naturally spread.
It wasn't just in the sky Chaos Star field. Even the surrounding star fields knew that the hidden Dragon General's mansion had a primitive god statue. Cultivating under this statue was very effective.
When the news of the hidden Dragon General's estate recruiting people spread, naturally, a large number of people came to join them.
Of course, these people who came to seek refuge couldn't make others swear on their life source. That was unrealistic. If that was the case, even if there was a primordial god statue to attract people, not many people would want to seek refuge.
