Since tangsan was 3 years old he started processing the art of paradise road which he prepared beforehand with many things he experienced for 3 years even though Tangdan only just started at the age of 3 years he had cultivated his eye skills because from the beginning Tangsan had received the internal eye of Magekyou, added to the amount of eye art he got from the heaven library but even though he cultivated his eye abilities there would still be limits because tangsan could not yet cultivate inner energy. Inner energy in this world can replace the chakra that is in the world of Naruto, but as a wild student from the sect he is not taught how to treat inner energy due to his physical growth and cannot hide his strength because small physical limits are very dangerous to find out that he could absorb energy from the outside and become his inner energy was one of the factors that weighed heavily on Tangsan's mind since he arrived at Tang Secte.
