Dinosaur Summoner

As Tang Ze celebrated his 60th birthday with his girlfriend, who had promised him a house, he couldn't have foreseen the extraordinary twist awaiting him the next morning.
Blinding light dazzled his eyes, the roar of the waves was deafening, and despite the sweltering heat, the sweat trickling down his forehead was from fear and bewilderment.
How could he have fallen asleep in his comfortable bed beside a beautiful woman, only to awaken on a deserted island?
"Ding! The summoning system has been activated!"

The response surged directly into his brain, accompanied by a robotic voice. And yet, amidst the confusion of new identities and acquired systems, one word seized his attention: "Belly."
Although an older man, he had always been an avid reader and a passionate anime enthusiast. That knowledge instantly resonated – he had transmigrated into the One Piece world.
Now armed with a mighty system that allowed him to summon dinosaurs, Tang Ze stood at the crossroads of an extraordinary destiny. He could become the legendary Pirate King, or perhaps even ascend to the rank of Marine Admiral. The choices were boundless, and adventure beckoned.
