After Three Years of Blindness, the Disciples Became Emperors of the Sea?

Lin Han came to the pirate world during the Rocks era, but found that he was blind. Fortunately, he activated the system and got the ultimate overlord color. The system informed him that as long as he accepts a disciple with S-level qualifications, he can become stronger. If the disciple achieves great achievements, it will give him a chance to restore his light! But when Lin Han was wondering where to find the S-level disciples, suddenly a little guy calling himself "Duokai" came to the door. A few months later, Kaido went to sea and shocked the world with his outstanding overlord color! Then Lin Han met Akainu and Kizaru, who were only more than ten years old, and taught them the correct use of armed colors. He met the still young and blind Fujitora Issei, and taught him the terrifying uses of sight and color. Barrett, who was only eight years old, took the initiative to come to the door and saw how terrifying it would be to reach the ultimate level of physical skills... Charlotte Lingling and Whitebeard Newgate also became Lin Han's disciples under Kaido's instigation. Then. Many years later, when Lin Han opened his eyes, he found that his disciples were all like emperors of the sea! This novel and its characters are purely fictitious.
