Prodigal son

Shikaku was not doing very good the last couple of years, he knew his son had a mental age beyond his 5-year-old appearance, but as a father he still worries for his son. When Shikamaru finally came back to the clan he was happy but also dreading what new troublesome thing the child would bring up now, His son asked him to sit and meditate while he transmits the information into his mind directly, he was shocked by the applications for such a technique but complied if only to know what his son had found, when he felt his mind receiving the information his eyes widened in shock, gods huh, how troublesome, but it looks like his son already had a plan.

Shikamaru watched as his father processed the information and was pleased that he was waiting to convey his plan, "dad I'm going to apply a seal on you that will boost your battle prowess and help immensely in our clan techniques, there will also be data on how I've improved or changed the clan techniques" He watched as his father mulled over his revelation for a while before nodding, So he got to work on applying his greatest creation, he named it 'the link to the shadows'.
