Looking at Dong Tianyu's energetic figure in front of him, the middle-aged man patted the young man next to him on the shoulder: "Xiao Li, you see, he can climb ten to twenty floors without a hitch. Look at your current state. You both are young, but how come there's such a big gap?"
Although Xiao Li had a mind to rebuff his colleague's mocking, his body was not allowing him to do so after climbing for more than ten floors. He hemmed and hawed, trying to keep up with the other person.
If it were simply climbing the stairs, they wouldn't appear so ragged. However, to keep Dong Tianyu in their sight, they had to stick closely to him.
But Dong Tianyu didn't want to waste too much time on the stairs, so he ascended quickly, which accelerated their exhaustion. Therefore, they were panting heavily.
Luckily they were about to reach their destination on the thirtieth floor, so they held their breath, earnestly following Dong Tianyu.
