Chen Mo left the house quite early because he was bringing Ling'er back in the afternoon.
Taking advantage of the ample time, he headed to the bank to retrieve the gold mine documents and took them straight to Sister Yun. He had always said the same thing, the documents were useless to him if Sister Yun wanted them, Chen Mo would gladly give them to her.
He would rather give them away for nothing than hold onto them, as long as they were going to his own people.
That's really what Chen Mo thought; if he were to sell them for a meager service fee, it would be better to give them away. Having a favor owed was far more valuable than any sum of money. Sister Yun was a capable person; giving it to her would mean her word might be worth even more than millions in the future.
Of course, that was assuming Sister Yun wanted them. If Lew Qingyi didn't want the mine, it was even less likely that Sister Yun would.
