Why Isn't the Lazy God Lazy?

I accidentally transmigrated into the Naruto world. Other people's Systems hand their Hosts all kinds of treasures and bloodline powers, but mine not only drains my energy, it also torments me in my dreams every night. Luckily, the System can use energy to transform my body, and everything I train for in my dreams becomes real. You only see how lazy I am during the day, but you don't know how hard I work in secret.

When I take a nap, no danger can come near me;

When I stretch, every powerful enemy is slain!
