Song Xiaotian asked Li Lingtian for thirty million Spiritual Stones when he arrived at the spaceship. He told Li Lingtian that the spaceship needed them.
Li Lingtian did not say anything and handed the fifty million Lower Spiritual Stones to Song Xiaofeng. The rest was considered a tip from him. Money could make the world go round. It was naturally worth it to have other Warriors work for him with just a few Spiritual Stones.
Song Xiaotian's face was filled with gratitude when he saw Li Lingtian giving him twenty million Lower Spiritual Stones for his hard work.
Generally speaking, it would be good enough for a powerhouse like him to safely earn one to two million Lower Spiritual Stones a month. Even for a Martial Emperor powerhouse, it was not so easy to earn Spiritual Stones.
