Summoning from Another World, Summoner's Summoner

Cheng Er swore that he just took a nap while standing guard and definitely didn't fish. Just by closing and opening his eyes, he came to a completely unfamiliar place, a place similar to a gladiatorial arena. Before he could recover, a roar of a beast that he had never heard before interrupted his thoughts, and then he saw a beast that he had never seen before that looked similar to a leopard but twice as big, staring at him with bared teeth, as if staring at a prey. This novel and its characters are purely fictitious. Any similarity is purely coincidental and should not be imitated.
