Conundrum

Three months later, an exit suddenly appeared and several people heaved a sigh of relief.

Seeing this, Jiang Yue also sighed and looked at Yu Nianzhen.

"You were right." He said with a solemn look in his eyes.

As Yu Nianzhen theorised, an exit appeared after two conditions were met.

The first condition was the day.

After the first fire attack, nothing happened until a month later.

On that day, another fire attack happened but this time, the fire was several times more powerful.

During that attack, twenty people died but the exit still didn't appear.

Another month later, the third fire attack happened.

As expected, the attack was more powerful than the previous two.

Fortunately, the fire disappeared after three people died.

Otherwise, even Yu Nianzhen and Jiang Yue would have found it difficult to survive.
