When Zen was 4 years old he was very smart. He read many books of literature, calligraphy, array formation and on herbs. He also read martial arts techniques. Zen's grandfather had collected them because he was in love with everything to do with martial arts even though he could no cultivate.
While using the divine sense, Zen comprehended all the information in a 1 day. During the process, he thought that he could poems, calligraphy, array and martial arts techniques and so he did. Zen spent 3 months doing that. His grandfather was amazed by the amount. He looked on the poems and they were all master pieces. Ren then looked on the paintings. His heart began to beat faster and faster. When he looked on the martial arts, he became silent for all of them were yellow grade. Martial arts techniques were grade from gray, black, silver, orange, yellow, red then gold.
That became a trigger for his grandpa's poor elderly heart. Ren collapsed on the floor. He was in the state on unconscious. When he was in coma, Zen was still creating things. On the fourth year of being in coma, he died.
