Qin Yi reached the sixth floor of the hotel, his breathing slowly calming down.

A 2000-meter run in under 7 minutes and 50 seconds.

Fifty standard military push-ups, two sets.

These were daily mandatory exercises left by his grandfather.

As his grandfather put it, "A strong body wins good battles; the exam hall is a battlefield. A sturdy physique is a crucial asset for victory."

As he stepped onto the small rooftop terrace, a piercing cat’s wail suddenly made his heart clench.

He followed the sound and instantly relaxed.

It wasn’t his cat.

It was a black tomcat in heat.

But… what was it doing on the sixth-floor terrace? The only female cat here… seemed to be just one…

Qin Yi walked toward the black cat, which was trying to call out a pretty female cat for a romantic night.

The black cat spotted him immediately, sensed his ill intent, and darted into the fire escape.

Qin Yi narrowed his eyes, lunged forward, vaulted over the railing, and jumped straight from the sixth floor to the fifth.

Just as the black cat reached the fifth-floor landing, Qin Yi, waiting in ambush, kicked it down to the fourth floor.

"Free upgrade to the fourth floor—good deeds done anonymously. I’m Lei Xiao Feng."

The black cat landed dusty and disheveled, scrambled up without delay, and fled—this freakish human was faster than it.

Qin Yi knew cats well: if you didn’t hurt them badly enough, they’d keep annoyingly coming back to bother you.

He had no intention of raising a litter of black tabby kittens, nor did he want to be the sucker raising another cat’s offspring.

Having efficiently dealt with the thuggish cat eyeing his little female tabby, Qin Yi calmly returned to the sixth floor and swiped Lin Jin’s door with his keycard.

That morning, while Lin Jin was sleeping, he’d asked the hotel manager to make an extra keycard for Lin Jin’s room.

The manager was reluctant at first, but then thought: the room was occupied by Lin Jin, a boy who was good friends with Qin Yi. What scandalous thing could he possibly do?

So he made the card, of course charging a 100-yuan fee.

The keycard slid over the sensor, triggering a soft beep.

The door opened.

The little tabby cat sat obediently by the door, looking up at its future caretaker.

Qin Yi’s eyes narrowed dangerously.

"If you dare go out looking for that black cat, I’ll neuter you on the spot."
