Yusuo, who was immersed in joy, was startled. What on earth was the Comprehensive System, and why did it suddenly appear in his mind?
[Host, I've been in your mind all along. I've been with you in this world for several days.]
Yusuo realized, "You are the Comprehensive System?"
[Yes, but the Comprehensive System is just my host. My true form is a system spirit, a fusion of art and technology during the glorious era of art. After the sudden changes in the world and the leakage of spiritual energy, the amount of spiritual energy that can sustain my normal operation has been decreasing. Just before the complete disappearance of spiritual energy from the world, to avoid complete dissipation, I attached myself to the library's management system.]
[That day, I sensed that my last bit of spiritual energy was about to run out. I had the idea to leave the library and take a look. So, I attached myself to the Comprehensive Art book you took with you. Who knew we were so lucky that your soul unexpectedly returned to the primitive era, and I came along with you!]
Yusuo understood. He knew what a system spirit was. In the glorious era of art and technology, there was a highly intelligent spirit famous throughout the entire art continent. It represented the highest integration of art and technology, overseeing the intelligent systems of the entire continent, a pinnacle of that glorious civilization.
Later, due to the changes in the world and the dissipation of spiritual energy, people were focused on their own survival, and no one paid attention to where that system spirit had gone.
[That system spirit is me.] The Comprehensive Spirit spoke with a shy tone.
Yusuo had guessed it. It seemed that this Comprehensive Spirit was not a simple entity.
Yusuo asked, "If you've been here all along, why reveal yourself now?"
Comprehensive Spirit: [I wanted to reveal myself earlier, but there wasn't enough spiritual energy to activate. If it weren't for the day you accidentally opened the first acupoint, allowing me to finally accumulate some spiritual energy, I still wouldn't be able to activate.]
Yusuo: "Can't you absorb spiritual energy on your own?"
Comprehensive Spirit: [I don't have a true form right now. Before I can reform my true form, I can only absorb spiritual energy through you. So strictly speaking, I am currently a magical tool bound to your soul, and you are now my master.]
Yusuo fully understood. He asked, "What benefits and drawbacks does binding you have for me?"
Comprehensive Spirit: [Many benefits. In addition to the content in the Comprehensive Art, I know a lot of things. Anything recorded in the data can be searched in my system. I can also perform scans, from body scans to large area scans. There's almost nothing I can't scan. I also have a storage space, super large, capable of holding a tremendous amount of things.] The Comprehensive Spirit said enthusiastically.
Initially, Yusuo found it plausible, but as he listened further, he became more calm.
Yusuo said, "Then, give me a big scan now."
The Comprehensive Spirit hesitated, stammering, "I really can scan. It's just that, well, my spiritual energy is insufficient now. I can scan at most ten times a day, and the range isn't that large."
"How large is it?"
[Within a radius of a hundred meters around you.]
"..."
"What about the storage space?"
[Right now, I can only open a space of about one cubic meter...]
"..."
After all, it seemed like it was all talk and no substance.
"What about the drawbacks?"
The Comprehensive Spirit spoke even more quietly, "It requires me to absorb your spiritual power because I can't absorb spiritual energy on my own right now."
Yusuo: "How much do you need to absorb?"
Comprehensive Spirit hurriedly answered, "Just allocate some from your daily cultivation for me. I won't be greedy."
Yusuo contemplated. Even if it was just a small portion, the amount of spiritual energy he needed to absorb every day would still increase. However, overall, the benefits outweighed the drawbacks. He could accept it.
"I have two requirements. First: You cannot absorb my spiritual power without my knowledge, and the amount absorbed must not exceed my tolerance. Second: Without my permission, you cannot probe into my thoughts."
Comprehensive Spirit: [No problem.]
"Words alone are not enough; there needs to be a contract."
The Comprehensive Spirit mumbled that Yusuo was indeed cautious, but it quickly found a contract document. It was a standard template used by the masters during the most glorious era of art. After Yusuo read it, he found no issues, so he signed the contract with the Comprehensive Spirit.
Comprehensive Spirit: [Now, can you rest assured?]
Yusuo: "Reluctantly. As long as you don't harm me, I won't mistreat you."
[Of course, I won't harm you.] The Comprehensive Spirit was able to have this encounter because it attached itself to Yusuo's mind. As long as Yusuo didn't mistreat it, it was quite satisfied. To showcase its capabilities, it even proactively said: [Actually, there's a set of acupoint impact techniques more suitable for you right now.]
Yusuo had it bring out the new method, and upon inspection, he found that it was a set of techniques passed down from the later period of the primitive era.
Comprehensive Spirit: [I found this in a corner of the database. In the later stages of the primitive era, the spiritual energy gradually became milder, and this technique fell out of use. There are only some records in ancient books, and only I have collected them.]
This technique was indeed more suitable, so Yusuo decided to try it now.
The Comprehensive Spirit, seeing this, didn't disturb him and obediently retreated into Yusuo's mind.
The night passed quickly. When it was almost dawn, Yusuo opened his eyes.
In just one night, he had opened all six main acupoints on his feet. It seemed that in a few more days, he could connect the current meridians and gather spiritual energy into his elixir field.
Comprehensive Spirit: [How does it feel?]
Yusuo: "It's indeed more effective than the previous method."
The Comprehensive Spirit was somewhat proud: [Of course, you see how useful I am.]
Yusuo gained benefits, and he didn't mind flattering it a bit. "Not bad, you're indeed quite powerful."
The Comprehensive Spirit was pleased with the flattery.
At this moment, it was still dark outside, and inside the house, it was as pitch black as the wilderness. Yusuo, who slept through the night, curled up like a child without a sense of security. Yusuo lifted the beast skin covering his stomach and tucked it up to cover his arms.
Yusuo hadn't slept all night, but he didn't feel tired. He quietly walked to the side of Jian Yunchuan, who lay on the pile of thatch, and asked the Comprehensive Spirit, "Can you scan people?"
The Comprehensive Spirit proudly replied: [Of course, during the most prosperous period, the medical systems of major hospitals were under my management.]
Yusuo: "Then
help me scan Dad and see what his condition is."
The Comprehensive Spirit gave a sound of acknowledgment and diligently went to work.
[He suffered a heavy blow to the head, leaving blood clots in his brain.]
Yusuo thought so. He asked, "Is there a way to solve it now?"
Comprehensive Spirit: [There's a prescription that can dissolve blood clots; you just need to find the ingredients.]
Yusuo glanced at the prescription and found that there were quite a few listed ingredients, including two rare spirit medicines.
The Comprehensive Spirit explained: [This is the best prescription, safe with no side effects. If you're in a hurry, I can also provide you with a more potent medicine.]
Yusuo: "No need, just this one."
Yusuo noted down the prescription and decided to go up the mountain and search when it was daylight.
When the sky was faintly bright, Yusuo began preparing breakfast.
He took the leftover pig offal, pig liver, and sausage from yesterday, cleaned them again, put them in a clay pot of boiling water to cook, added wild vegetables and mushrooms. When it was almost done, he took the pot down, woke up Yuzhou and Jian Yunchuan, and had breakfast together.
It was fortunate that the temperature was lower last night; the food didn't spoil and could still be eaten.
With several meals in a row having meat, Yuzhou and Jian Yunchuan were both very happy. Jian Yunchuan, who was originally hostile to Yusuo, even softened his gaze a lot. Sometimes, when Yusuo said something to him, he would be willing to listen a bit more. It seemed that he wasn't as unruly as before.
After they finished breakfast, Yusuo brought his sister Yujing over to find Yuzhou.
After spending a day together yesterday, Yuzhou and the others became somewhat familiar with each other and weren't as repulsive at the beginning.
Yusuo instructed them a few words, seeing that they were getting along fine, then took his spear and left.
By the time he reached the village entrance, most of the hunting team had gathered, and the sun had just come up.
As soon as Yusuo arrived, several people greeted him.
After yesterday's impressive performance of kicking the wild boar, the members of the hunting team recognized Yusuo. Only a few people who were friends with Yusuo's brother, Yusuo Da, didn't have a good expression when they saw Yusuo's face.
"Dawdling, everyone's been waiting for you alone." Yusuo Da complained.
Yusuo hadn't said anything yet when Yufeng glared at Yusuo Da first. "I just arrived too. Do you have a problem?"
Reluctantly, Yusuo Da shut his mouth. He couldn't figure out why Yufeng always spoke up for Yusuo. Clearly, he was the older team member.
The hunting team quickly set off. Today, there was no specific destination; they were going to find prey.
This was just what Yusuo wanted. He reminded the Comprehensive Spirit to open the scan when they reached the mountain to see if there were any medicinal herbs to discover.
Comprehensive Spirit: [Understood]
