Sometimes, An Zhe felt guilty for their kindness. It was because he wasn’t human and he felt this kindness was for the human skin he stolen. He started to fear that the prototype would be revealed on he day he died.

He once told Polly that there was no need to worry about this. At that time, Polly used the back of his hand to test the temperature of An Zhe’s forehead and whispered, “You are like my child.”

In Polly’s absence, he asked Run why Mr Polly was so kind to him.

Rum had replied, “Sir loves everyone here.”

“Half of my body was mouldy when I came to the institute and my consciousness wasn’t awake.” Rum rolled up his trouser legs to show his sturdy calves full of scars and bulges like earthworks. The always taciturn man spoke a long sentence, “He spent half a year saving me, regardless of day or night. I couldn’t believe there was such a person in the world.”

He also added, “I wasn’t a good person previously. I killed my teammates when I was a mercenary and now I have rescued three compatriots from the outside, which is atonement. It is good to be a good person and it is better to be a person than a monster. Many people here are like me. There is no one who doesn’t love Mr Polly.”

An Zhe clearly remembered that at that time, he inexplicably thought of what Lu Feng was doing. Immediately after, he shook his head and kicked the silhouette of that person who was the complete opposite of Polly out of his head.

Rum was an amateur music lover. When he had nothing to do, he would play the harmonica from worn-out sheet music and he would sometimes teach An Zhe. The sound was pleasant but Rum said humans had instruments that were millions of times better than the harmonica. Together, they could play an extremely magnificent symphony.

At this time, Polly came to them and joked, “If Run had been born 100 years old then he would’ve been an outstanding musician.”

The always reticent Rum smiled and then took out a worn radio. He turned the tape over and pressed the play button. An intense or gentle rhythm would be emitted from the rusted machine. It was the sound of countless instruments, each with its own tone and melody. These sounds and melody combined to form another magnificent sound. Music reverberated in this laboratory. Below the white building, a man whose left arm had turned into a beast’s claw beckoned this way. Rum hung the radio on the outside railing and turned up the volume.
