All the children had a premonition that upon entering, they might face something even more terrifying than the experiment, perhaps... death.
So on the last day, Tong Xi ran away.
At that time, there were seven other children labeled as "failures" who escaped with her.
A woman from the lab helped them escape; she was the most reliable assistant of the Doctor, and no one doubted her.
She was a good person, only a few years older than them, a genius who often got food for them secretly and would give them candy when they were in pain.
With her help, their escape went smoothly, but even so, a few children were captured and brought back midway.
Tong Xi did not dare to look back, she could only run all the way, hiding in a train parked by the roadside, reaching the city with the train's journey.
She found a secluded alley as her shelter, scavenging for food in the garbage every day or picking up food discarded by passersby.
