Seeing Zhang Heng and Fan Mei Nan's reactions, Ma Lu wavered for a moment.
But he still found something so surreal difficult to accept. A tunnel with no end sounded absurd.
Yet he had indeed seen Zhang Heng pick up that one-yuan coin from the ground. Logically, no one should have entered this tunnel since it had been abandoned fifty years ago. One-yuan coins had not even been designed back then, so the coin could only have been dropped recently.
Of course, there was another possibility: it had been left behind by the two people who had jumped down from the platform earlier. At that thought, Ma Lu's eyes lit up again. He felt he had found the only possible explanation. What he did not understand was why Zhang Heng would lie about this. Thinking back to how Zhang Heng had insisted on hearing the rumors about this place, it seemed he had deliberately been trying to make the atmosphere more frightening.
Only then did Ma Lu remember that he did not actually know Zhang Heng and Fan Mei Nan's identities. He had not cared much about it before. After all, anyone who was not new to the workplace knew that less trouble was better than more. Zhang Heng and Fan Mei Nan had been assigned by their superiors to participate in the rescue operation, and Ma Lu had always been polite to them.
But now he could not help wondering about Zhang Heng and Fan Mei Nan's identities. Their attitudes had seemed strange from the beginning, and they focused on different things than ordinary people did. What happened next surprised him even more: Ma Lu watched Zhang Heng set the large travel bag he had been carrying on the ground.
He opened the zipper and took out a longbow.
