Naruto: I'm Really Not Sick, That's a Burst Entry

Traveling through the Warring States Period of Naruto, Gen Uchiha awakens [Entry Plunder Synthesis System]. I thought I would be able to pull out the proud magical skills, but it turned out that the novice gift package actually contained an out-of-print golden entry: [Born to be sick and weak (fake)]! [Effect of entry: face as white as paper, frequent coughing of blood. The weaker you appear and the more blood you vomit, the more terrifying your combat power and critical hit rate will be! Thus, during the cruel Warring States Period, a peerless ruthless man with a unique painting style emerged. On the battlefield, Uchiha Gen was coughing blood crazily and was shaking, while he smashed the mountain with a backhand punch. Uchiha Madara's eyes were about to burst, and his eyes filled with tears: "Xuan! Why are you blocking the knife for me when you are seriously ill? Get out of here!" Senju Hashirama's face was filled with anguish: "How can we attack such a gentle and fragile young man? The Senju clan, retreat!" The enemy soldiers from all walks of life were trembling: "You call this weak? He was vomiting blood while using his full body Susan and killed us in seconds!" Uchiha Gen wiped the blood from the corner of his mouth and sighed helplessly: "I'm really not sick, I just had an itchy throat... System, combine [Shura Soul] and [Immortal Human Body] for me!"
