He Yongxing did not leave; he had been outside all along, merely avoiding Bai Zhizhan.
He called Bai Zhizhan over and had Zhu Shijian inquire about the development plans of the Navy under the guise of seeking advice, but in fact, it was He Yongxing's intention.
To make Zhu Shijian take notice of this young officer, He Yongxing brought up the matter of the naval battle at Watcher Strait.
Indeed, it was without possession of any definitive intelligence, without knowledge of the backup battle plan, that he accurately judged the time and place of the encounter with the first Battle Patrol Squad. Moreover, he boldly presented his views during discussions, persisting in his own despite facing skepticism.
According to He Yongxing, having a keen intuition wasn't anything extraordinary; what was key was the high level of confidence in that intuition, a truly invaluable quality.
Of course, it would be more accurate to call it a talent.
