After Han Feng reviewed the new tasks assigned by the system, he sensed that Zero had changed. He used to be a threat to Zero, but now he seemed different...

"Zero," Han Feng said to the virtual boy, "What changes have you noticed since upgrading to version 3.0?"

"Yes, I feel like I'm even more handsome now."

"...Can't you speak properly?" Han Feng was speechless. Where did you learn this from?

The virtual little boy sat up abruptly and said to Han Feng, "Okay, then I'll explain properly."

Then, with a wave of her hand, a light screen visible only to Han Feng appeared in the air, displaying a row of neat characters:

Name: Han Feng

Age: 19

Skills include: Master of hand-to-hand combat, Master of firearms, Master of assassination, Financial genius, Precise insight, Divine medical skills, Academic proficiency, Professional driving skills, Detection radar, and Weakness scanning.

Looking at the information on the screen, Han Feng asked, "Isn't there a level system? I remember you said that after upgrading to 3.0, each skill level would be upgraded, so why isn't it showing up now?"

Zero scoffed: "I just think you're too weak. You're having so much trouble even with a defective item. If you don't improve, what will you do later..."

"What about later?" Han Feng seemed to understand the implication in the words and asked curiously.

"It's nothing. In short, you're still too weak right now. And as for the system's affairs, you should stay out of it." Zero seemed a bit mysterious, but she just wouldn't tell Han Feng anything.

Han Feng was also somewhat helpless, and then asked the question that had been bothering him: "What is the reward for that hidden quest?"

"You mean the star network diagram?" Ling tilted his head, revealing a half-smile.

"Yes, what does this reward mean? Explain it to me,"

Ling scratched his head, seemingly wondering if he should tell Han Feng about it. But then he thought, since he knew anyway, he might as well tell him little by little.

"Han Feng." Ling unusually didn't address him as "host."

"Huh?" Han Feng was a little surprised. Why was the system calling him by his name?

"Do you think there are anything in the universe or galaxies that is similar to the human body?" Zero asked very seriously.

"Why are you asking this? I'm asking you about the star network diagram."

"Answer my question first." Zero's tone left no room for argument.

"Uh... I don't know either, it just feels like a lot of things are just coincidences," Han Feng said truthfully.

"Then do you think the power possessed by a knight, a person who has been modified, is extraordinary?"

Han Feng seemed thoughtful after hearing Ling's words.

Since knights are the failed foundation of ancient martial arts families or overseas clans, they are indeed a force to be reckoned with compared to ordinary people.

"In fact, so-called ancient martial arts are just some cultivation methods."

Han Feng was astonished: "Cultivation? Zero, you haven't been reading too many cultivation novels, have you?"

Zero ignored Han Feng and continued, "Actually, if you correspond to certain things, you can discover some things."

Han Feng also became interested: "For example?"

"There are twelve months in a year, just as there are twelve meridians in the human body. There are four seasons in a year, just as there are four limbs in the human body," Zero said.

Han Feng immediately realized: "You mean, the body corresponds to certain nodes on Earth?"

Zero nodded: "Think about it again?"

Han Feng continued to think, but the more he thought about it, the more unbelievable it seemed: "Humans have seven orifices, corresponding to the seven days of the week, the twenty-four solar terms of the year, the twenty-four vertebrae, the five elements of heaven and earth, and the five limbs and bones?"

"That's right. Just as the heavens have five phases and six qi, humans have five internal organs and six bowels. There are 365 acupoints in the human body throughout the year."

Han Feng was filled with dread as he thought about it. He looked at Zero incredulously: "You mean that ancient martial arts families cultivate...?"

"Each corresponding part has its own cultivation method. It's not the kind of immortal cultivation in novels, which is somewhat unrealistic."

"What does that have to do with the star network diagram?"

"The Star Vein Diagram is the key to unlocking cultivation; what those ancient martial arts families cultivate is only a superficial understanding," Zero continued.

"And what about this star network diagram?"

After a moment of contemplation, Zero explained, "I don't know how to explain it to you. You can think of it as cultivating immortality. Anyway, once you've mastered this, you'll be at the level of ascending to immortality in your novels." It really didn't know how to tell Han Feng, so it could only say this.

"Isn't this still cultivating immortality?" Han Feng was speechless for a moment, but he seemed to have sensed something from Zero's words, so he continued to ask, "Do you know something?"

"Knowing this too early won't do you any good." Zero guessed what Han Feng was thinking and ended the topic directly.

He paused for a moment and continued, "By the way, you haven't used the system space much before. I upgraded it this time, and there are some changes. You can take a look when you have some free time."

"You could have just told me directly, why go through all this trouble?" Han Feng said, pursing his lips.

“Last time, I made the decision to help you directly absorb the life potion, which was already a violation of the rules. So after this upgrade, unless I issue a mission or provide necessary reminders, I cannot provide you with any other assistance. Otherwise, I will be eliminated,” Zero said solemnly.

Before Han Feng could react, Zero waved his hand and said, "Alright, this system needs to rest now. Good luck to you. But I'll let you in on a secret."

"What news?"

"It's a bit premature for you to get involved with ancient martial arts families. I don't know if it's good or bad for you." After saying that, Zero's figure turned into starlight and disappeared.

No matter how Han Feng called out to him, there was no response.

Han Feng sat blankly on the sofa, thinking about what Ling had said. What cultivation, what star meridian diagram—it all seemed increasingly absurd to him. But based on Ling's reaction and what Liu Xiaoran said about ancient martial arts families, Han Feng had to take it seriously. Maybe it was true.

Just then, the door opened, and a chattering sound came from inside. It turned out that Su Wanwan's parents and their group had returned. Suddenly, it started raining, and they lost all interest in continuing their sightseeing.

As soon as Su Wanwan entered the house, she ran around frantically looking for a towel. Han's parents went to the living room, where Liu Mengran was also present.

Han Feng asked, "Why are you back so soon?"

Liu Mengran chuckled and said, "Look, it's raining, isn't it? My aunt and uncle said they had to come back first, and there really wasn't anywhere good to go with the rain."

"The weather was perfectly fine and then it suddenly started raining, really," came Su Wanwan's resentful voice from upstairs. "We haven't even had a proper look around with Uncle and Aunt yet."

Han's mother sat on the sofa and said with a smile, "It's alright. We've been to quite a few places today. We'll go see more tomorrow."

Mr. Han chimed in, "Yes, that's enough for today. We should take our time to see the good places."

"Okay, okay, then I'll take Uncle and Auntie on our next trip tomorrow!" Su Wanwan had already come downstairs, holding three towels which she handed to the group.

"Okay, you must be tired after playing all day. I'll go cook for you." After saying that, Han Feng got up and went into the kitchen.

"Let me help you." Liu Mengran rolled up her sleeves and was about to walk over.

"No need, you've had a long day, go and get some rest," Han Feng said to Liu Mengran with a smile.
