Three years passed quickly.
At Konoha Hospital, two nurses in white uniforms pushed an emergency bed toward the operating room. The nurse in front shouted, "Excuse me, please move!"
A man in a ninja outfit lay unconscious on the bed. The nurses rushed him into the operating room. " Sir, please hurry. He is from the security team. They said he fainted at the village gate," the nurse called to the medic on duty.
The medic hurried to the bed. A wound on the man's chest oozed blood. Then he cleaned the bloody wound and frowned. "It is poison. Yukino, Dosuke is on duty. Get him now," he said.
"Got it," Yukino said. She ran out, pushing through the crowded hallway to the medical office.
She burst in. "Dosuke, Dosuke, emergency patient. Get ready!"
Dosuke set down his book beside a steaming teacup. He turned to the sweating nurse. "Slow down, Yukino. Tell me about the patient."
Yukino caught her breath. Dosuke's short hair was tied in a neat ponytail, two bangs framing his face. His white short-sleeve shirt made his skin look fair. With the book and teacup, he seemed like a quiet student, not a ninja. "The Konoha Security Force sent him. He was on a mission team. Only he returned alive. Yasumoto says it is poison. He needs you."
"Thank you, Yukino," Dosuke said. He grabbed his medical ninja uniform from a hanger and slipped it on. The loose uniform hung on his slim frame, but he looked sharp, not silly. His slippers clicked as he stood. "Let us go."
"Okay," Yukino said, snapping out of a daze.
As Dosuke walked through the hallway, people greeted him. "Dosuke, thank you! Dosuke, where are you headed? Thank you, Medic Dosuke!"
Since becoming Tsunade's student, Dosuke spent his days at Konoha Hospital and nights refining chakra and ninja techniques at home, sleeping just four hours each day. He rarely trained in the forest now. At first, he only assisted, using the Mystical Palm Technique for small wounds. Now, he was a skilled medic.
For three years, Dosuke worked tirelessly. He helped Tsunade develop the Strength of a Hundred Seal, though Tsunade did the work but Dosuke offered ideas.
He also healed many villagers with the Mystical Palm Technique, earning their gratitude. Not everyone could afford medical ninjas, so Dosuke's kindness made him popular among Konoha's civilians.
* Might Guy sometimes complains I am never around to heal his training injuries * Dosuke thought, smiling as he passed the crowded halls.
He reached the operating room and pushed open the door. Medic Yasumoto was treating the patient. "What is the situation, Yasumoto?" Dosuke asked.
"Dosuke, you are here," Yasumoto said. "The patient is weak. I stopped the bleeding, but the wound is rotting, black and purple. It is a strong poison."
"Can you identify the poison?" Dosuke asked.
"No, he is in a coma. We do not know where his mission was," Yasumoto said, glancing at the ninja.
Dosuke placed his hands over the wound. Chakra flowed into the patient's body. "The blood seems normal, but the wound is rotting. His breathing is weak, and his kidneys are failing. It is likely a mixed toxin. We need tests to know more," Dosuke said.
"Dosuke, he cannot wait for tests," Yasumoto warned, eyeing the patient's shallow breaths.
"Understood," Dosuke said. "Yukino, remove his clothes. Yasumoto, prepare surgical tools and distilled water. Since we do not know the toxin, we will extract it first."
Five minutes later, Yasumoto said, "Dosuke, it is ready."
Dosuke's hands glowed with chakra. He formed a Chakra Scalpel, a precise blade of energy, and cut the ninja's nerve lines to prevent movement during surgery. "Water," he said.
Yukino brought a large basin of water. Dosuke dipped his hands in, gathering chakra into a water ball. He placed it on the ninja's wound. Under his careful control, the chakra-filled water seeped into the body. Toxins rose from the wound, turning the water black and purple.
"Change the water," Dosuke said.
Yukino swapped the basin. Dosuke repeated the process twice. The water stayed clear. The ninja felt relief as the toxins left.
"Scalpel," Dosuke said. A silver blade flashed in his hand. He cut away the poisoned, rotting flesh. His hands glowed green. "Mystical Palm Technique," he said, healing the wound. The ninja's cuts closed, and he slipped into a deep sleep.
"Yasumoto, admit him to the hospital. Someone will question him when he wakes," Dosuke said. He collected a sample of the toxin in a test tube and left the room.
"I understand."
In the laboratory, Dosuke studied the test results. His face grew serious. "This is bad," he said.
