A small test?

To develop this world's technology tree, or rather, its medical technology tree, someone must guide me through systematic learning.

Thinking of the classic trope of seeking a master from his past life, Xing Ran didn't believe that with the persistent, grinding effort of Shaolin Temple, he couldn't move Grandma Qiu to take him in.

Sigh, if only Tsunade were in the village, at least there would be a better option. Putting aside other things, with his current gambling skills, reaching a level of mutual learning would be highly promising. Unfortunately, in the village right now, the only medical ninja masters Hai Yi was familiar with were of Grandma Qiu's caliber, and there weren't many. In any case, Xing Ran had no better reason to approach the others, so he could only try to pick fruit from Grandma Qiu's tree.

Adjusting his mindset once more, Xing Ran began visiting Grandma Qiu's shop every day. He wasn't a man of few words and clearly stated his desire for Grandma Qiu's guidance. Following that, came days of being a volunteer, and more volunteering.

Half a month later, Xing Ran had confirmed Hai Yi's cultivation method. It was effective, but for him, it was like a drop in the bucket, only serving as a marginal improvement.

One day, Xing Ran arrived at Grandma Qiu's shop as usual. It was still early, and not many people were buying groceries. There was only a little old man in the shop.

Xing Ran naturally slipped into volunteer mode. After half a month of on-the-job training, he was already a qualified grocery store auntie. First, he'd recommend the shop's backlog of products, then ask what the customer wanted and how much.

However, before he could finish his three-part service spiel, the little old man interrupted him.

The old man was quite bald, with age spots creeping onto his face. He held a plastic bag in his withered hand. It was then that Xing Ran noticed there was already a dead fish in the old man's plastic bag.

"I... I bought this fish yesterday. I planned to eat it after keeping it for a day, but... but it died last night. The fish wasn't fresh when you sold it to me. I... I want a refund... or a fresh one..." The old man tried his best to sound aggressive, but his clearly lacking confidence made Xing Ran suspicious of him.

"Grandma Qiu? Did you sell this fish yesterday?" Xing Ran wasn't sure. He had taken over almost all the work in the shop during this time. Even with a less-than-stellar super-brain, Xing Ran wouldn't have memory lapses. He had never sold a fish to this old man. Could he be trying to scam him?

"...I'm old. I don't remember clearly." Since Xing Ran started volunteering, Grandma Qiu's work had been reduced to bookkeeping and petting cats. She was currently lounging lazily on a deck chair, soaking up the sun.

Normally, it would be perfectly fine for the frail old lady to utter "I'm old, I don't remember." But Xing Ran thought, I don't believe you for a second. Her little ledger clearly recorded even the time the orange cat stole a fish that jumped out of the pool, so there was no reason she wouldn't remember yesterday's events.

"Refund, or give me a fresh one. Otherwise, I'm not leaving." The old man's eyes darted around, realizing things weren't simple. When did this shop get a young man who looked so energetic? Without giving Xing Ran time to pursue the matter, his plan changed, and he activated Plan B.

Seeing the old man about to sit on the ground and start his "little motor," Xing Ran was speechless. What the heck is this sense of déjà vu from my past life? If you want to scam someone, go do it on the street.

The old man saw from Xing Ran's expression that the young man was bewildered by his combo move. His smile gradually became shamelessly wide.

"There will be no refund, nor will I exchange a fish for you. The habit of this fish is to play dead. Stimulate it with chakra, and it will wake up on its own." Xing Ran knew Grandma Qiu wasn't going to intervene, acting as if she couldn't see the old man causing trouble on her turf. Xing Ran knew he had to handle this himself.

As an apprentice without human rights, anything could be a test in front of his master. Recalling how long he had been volunteering here, in a normal script, this would be the time for the master to set a test to see the student's character.

Considering he was here to learn Medical Ninjutsu, and the "dead fish" which was a common practice tool in the Naruto world, the intention was too obvious.

Xing Ran put on a kindly threat, no, a smile.

He took the dead fish out of the plastic bag with one hand and activated the Mystical Palm Technique. Since he had experience reviving a dead fish before, doing it again was very easy.

Within the few seconds it took to take the dead fish out of the plastic bag and present it to the old man, after a flash of green light, the fish in front of the old man suddenly came back to life and started wriggling.

"This... I'm uneducated, don't lie to me. This is Medical Ninjutsu, right?" The old man feigned composure, speaking righteously as if to prove his innocence, saying, "You're all bad people, bullying this old man who lacks culture." But his body was honest. He snatched the dead fish, put it back into the plastic bag, and scurried away.

Xing Ran's lips curled into a smile. He looked triumphantly at Grandma Qiu, who seemed to be fast asleep on the deck chair. This question was too easy. Are there any harder ones?

However, Grandma Qiu clearly had high standards and wasn't impressed by Xing Ran's triumphant display, appearing as if she hadn't woken up yet. Only the little orange cat betrayed Grandma Qiu's inner turmoil. The poor orange cat had inexplicably fled and was trembling behind Xing Ran. A bald patch on its back was extremely unsightly. This... was from being petted bald just now. The young orange cat had endured pain beyond its years.

In the evening, after a day of a terrible volunteer experience, Xing Ran was preparing to go home when Grandma Qiu, who had almost merged with the deck chair, suddenly called out to him.

"Who taught you the Mystical Palm Technique?" Grandma Qiu's tone was somewhat unfathomable. Xing Ran didn't know if Grandma Qiu's reaction to him already knowing the Mystical Palm Technique was positive or negative.

"Not bad, right?" Xing Ran asked tentatively.

"Crude, a waste of chakra, and a waste of cell lifespan. No wonder you want to learn from me. Was it a veterinarian who taught you?" Grandma Qiu mercilessly criticized Xing Ran.

However, Xing Ran wasn't unhappy. Judging by Grandma Qiu's words, was she going to take him in? Yes, train me, this unlicensed veterinarian, into a qualified military doctor!

"No one taught me, that's why it's like this. My apologies." Xing Ran knew it was time to show his talent. Are there any self-taught geniuses? You have one right in front of you. Aren't you going to be amazed and take me as your final disciple, leading me to the peak of my life?

"Hmm, self-taught." Grandma Qiu's expression was calm, as if they had just reached an awkward point in the conversation. She lay back down on the deck chair, leaving Xing Ran bewildered. That's it? The script is wrong. So, your true form is that deck chair, right? You were so excited to see such a genius that you revealed your true form?
