"Of course, do you have a clear understanding of brain structure?"
"Not entirely, but it's fine. With my skill level, I'll understand it after just one look."
"Alright, I have a surgery scheduled right now. You can come with me, and I'll guide you through it on the spot."
"Okay."
Zhou Hong followed the surgeon into an operating room.
The operating room was brightly lit, and one couldn't tell it wasn't on Earth.
"Is everything powered here now?" Zhou Hong asked. He could replicate all the buildings and objects from Earth, but not electricity.
"Yes, the power was just connected last month. Your sub-world is very rich in coal resources, so we're generating electricity from coal. Once the power is on, everything in this world can gradually start functioning."
"Oh, I see."
On the operating table in the room lay an elderly man, already anesthetized. This elder was over a hundred years old.
"Dr. Wang, the preliminary work for the surgery is ready. We can begin," the surgical assistant said to the surgeon.
"Alright."
Zhou Hong asked, "Why is it an old man?"
"Senior Zhou Hong, don't you remember? In your sub-world, the rules of the world are different. People don't get sick before the age of 100. So now, our hospital is going out of business. The only patients we see are those over 100 years old."
"Heh, I almost forgot. You mentioning it makes me recall," Zhou Hong chuckled.
"So what is this old man's illness?" Zhou Hong asked.
"Replying to Senior, this elder has a glioma. It's in the middle to late stages, and the tumor is quite large. The most difficult part is that the tumor is adhered to a lot of brain tissue. However, the good news is that there's no metastasis. If the tumor can be completely removed, the survival rate is high. But unfortunately, that's almost impossible. It's in the brain, and completely separating it from the brain tissue would damage other tissues. So, we can only do our best."
"Alright, why don't I just do it directly?" Zhou Hong said, looking eager to try.
"This...!"
"What, you doubt my skills? Even though it's my first time, I can assure you I'll do better than you. You just need to tell me what to remove."
"Then alright." The surgeon broke out in a cold sweat.
Soon, the surgery began. The old man's skull was opened, and under the surgeon's guidance, Zhou Hong completed the surgery effortlessly, and with a perfect score.
"My heavens, this is impossible! How could you achieve this?" The surgeon was dumbfounded. He had been practicing for decades and couldn't achieve such dexterity. To separate the diseased tissue without harming the brain tissue even a tiny bit was like performing surgery on the delicate inner membrane of an eggshell, trying not to damage the yolk or white. It was incredibly difficult, especially with complex adhesions.
Yet, Zhou Hong, in such a precise and highly difficult surgery, managed to be so accurate, with not a single deviation. This was already surgery on a micron level. The surgeon suspected Zhou Hong was just showing off.
"This is correct, right?"
"Senior, you're too amazing. Have you done this before?"
"How could I? I followed your guidance. You said to completely detach these parts, and I detached them. Isn't that very simple? Alright, while we're at it, tell me how to perform the surgery I need to do."
"Okay, the surgery you need to perform is to restore this pituitary gland to its complete state and reconnect these nerves...!" The surgeon explained to Zhou Hong point by point, very detailed.
Half an hour later, Zhou Hong felt there were no issues at all. He now had a relatively clear understanding of the entire brain structure.
"No problem, absolutely no problem," Zhou Hong grinned.
Feeling confident, Zhou Hong left the operating room. Of course, as he left, Zhou Hong took a set of tools. After all, some very fine instruments were needed, especially some absorbable sutures and other materials.
After leaving the hospital, Zhou Hong returned home, intending to stay for one night and go out again tomorrow morning.
To Zhou Hong's surprise, no one was at home.
"Strange? Where did everyone go?" Zhou Hong gave a wry smile. If he wanted to find them, he could do so with a single thought, but he was too lazy to disturb them.
Since no one was home, Zhou Hong decided not to stay.
He instantly left the sub-world and returned to his dorm room in reality.
"Mentor Lu, are you there?" Zhou Hong took out his identity plate, which could also contact Lu Qianqian in reverse.
As expected, after a few seconds, Lu Qianqian's mental message came through the identity plate.
"I'm here. What's up?"
"I'm ready. We can set off now to treat your father's illness."
"Didn't you say you'd go tomorrow morning?"
"I thought about it, and I can go now. There's no need to wait until tomorrow morning. We only have three days of vacation, and one day has already passed."
"Alright, then let's meet at the main gate of Tai Gu Academy."
"Okay."
Zhou Hong immediately went to the main gate of Tai Gu Academy. As expected, Lu Qianqian was already waiting there.
In fact, Lu Qianqian didn't believe Zhou Hong could cure her father's illness. After all, so many renowned physicians had treated her father for this difficult condition before. Her father was willing to offer his beautiful daughter as a reward for treatment, willing to marry anyone as a consort. Unfortunately, even with such an incentive, no one could cure him. In short, no less than ten thousand people had tried to cure her father's illness in hopes of becoming a consort, but none had succeeded.
Zhou Hong was merely the 10,001st, and the weakest at that.
However, the reason Lu Qianqian brought Zhou Hong back to try was out of desperation and helplessness. Even with a one-in-a-billion chance, she wouldn't let it pass.
"Mentor Lu, you're so quick."
"My place is close to the main gate. Zhou Hong, are you ready so soon? What preparations did you go back to make?" Lu Qianqian asked curiously.
"You wouldn't understand if I told you. Let's go to your place. By the way, can we reach it in one night?"
Lu Qianqian nodded. "Yes, my home is on Tian Yang Continent. You could say I'm a local."
"This Tian Yang Continent is so vast, isn't it all your family's territory?"
"How could that be? On Tian Yang Continent, there are 12 super empires, 20 intermediate empires, and 50 small countries. The Supreme Empire controlled by my father is one of those 50 small countries, and it's about half a day's journey from Tai Gu Academy."
"Oh, I see. Then let's depart."
"Okay." Lu Qianqian immediately took Zhou Hong and set off for the Supreme Empire.
Although the Supreme Empire was a small country, that was only relatively speaking. If compared to Zi Xiao Continent, the land area of the Supreme Empire was ten times larger than Zi Xiao Continent.
