Bai Wen Zheng played his cards well this time, revealing only Kang Chen's secret marriage and withholding the news of their divorce, surely keeping some cards in hand.
There is also the news of Ming Mei's pregnancy. Kang Chen is unsure if Bai Wen Zheng knows about it. If he does, it's another card in his hands, as to how he will play it... probably just twisting the facts on a large scale to frame Kang Chen.
However, these things do not greatly affect Kang Chen. He doesn't care.
If he can withstand the storm of bullets on the battlefield, then these minor matters are nothing to him. He doesn't care at all.
What Kang Chen cares about is only Ming Mei. He worries that this matter will affect Ming Mei, and may harm her pregnancy.
Huo Er understands Kang Chen's plan to deceive the world and protect Ming Mei, not letting the rumors and slander from the outside world disturb Ming Mei.
This time, he's determined to protect her and the child completely!
