The boy then set down and thought, the great shadow clone Jutsu have the capacity to create a copy of him with all his memories, then the copy have the same thinking ability and characters of him. Which means that the copy is just another him who can do the same thing as him, and He can have all his memories, doesn't that mean that He can train his hand seals with the copy and have the memories of his training and his copy's training.
The child then began to use the shadow clone Jutsu to create one clone, he tried but failed since he didn't master the hand seals, however he persevered till he succeeded, once created the boy wanted to speak to the clone but the clone had beaten him on it.
The clone : You don't need to tell me what to do as I am you and know your thoughts.
The boy : Thats good.
Then the boy and the shadow clone began training on their hand seals to make it good enough, after all the reason the boy think he failed the Jutsu is that his hand seals are not good enough to be used, why ? Because each time he tried the Jutsu somehow or another he felt pain, this mean that the path that his chakra followed is wrong which means that for each hand seals there is a specific chakra path for the chakra to pass from, and the chakra pathway change slightly each time a new hand seal is introduced.
Thinking till now the child had already a big idea of which pathway is the principle one and which of them is the connector, after all the child had found out that each time he did a hand seal, the chakra pass by a specific pathway, but from a pathway to another the chakra need to pass by a specific passage, however some time their is more than one passage or there isn't any without forgetting that their isn't any difference between the passages and chakra pathway since the passages are the chakra pathways.
The child then figured out that the reason for the disappearance of the entrance is because in the first hand seal the chakra passed not only by its specific pathway but also by the other passages.
He also figured out that they may be more than one right passage but not all the passages are right.
Following this the child decided to focus in his practice but with his clone for the rest of the day till the sun began setting.
The child then dispersed his clone and chose to have a hundred percent of his clone's memories.
He then felt a headache taking over him however it wasn't without reward as he found out that he is more familiar to the hand seal than before and that their is more things that he didn't pay attention to but his clone did and things that his clone didn't pay any attention to but he did.
The boy wondered how many things their is that neither he or his clone put attention to.
He then decided that from today onwards he will always train with his clone, he then began to think what may happen if he trained with more than one clone, and so he decided to try it out tomorrow after his breakfast.
The child then go back to his little home, ate the food that he found in his plate and slept till the morning were he ate the food and gone back to the forest before he was found.
