Marvel: I Can Ninjutsu

Lin Yang travels through Marvel and comes with a ninjutsu skill book. He is an ordinary person and has little chakra. What should he do? I heard that Kyuubi's infinite chakra is due to the "Vulcan Seal". The skill book deduced that there is too much chakra to use up! What should I do if I don't have the Sharingan or the Immortal Body, my physique has nothing to do with Otsutsuki, and the upper limit is low? I heard that the Sharingan and the Senju body are manifestations of Yin-Yang escape. If you deduce it from the skill book, I want to be the ancestor of Uchiha and Senju in Marvel!
