An Impossible Possibility

Shi Xiaobai was certain that all the rookies had already left Dragon Mountain Valley because he had specially checked the valley before he left. He had confirmed that everyone had left.

Furthermore, the valley was open and expansive, even if a rookie had been playful by playing hide and seek, it was impossible to hide.

But at this very moment in time, the Absolute Choice had failed. It meant that a rookie had died without Shi Xiaobai's knowledge.

How did this rookie die?

Why did the rookie die so silently?

Shi Xiaobai was completely clueless. This was more mysterious than the rookie being killed by invisible monsters.

Shi Xiaobai could only use the time he had to choose for speculation.

Maybe there was really someone left behind in Dragon Mountain Valley? For example, the person was swallowed whole by a monster, dying only a period of time later?
