Du Gu Bo's change seemed so easy, perhaps because of his absence for over a month.
Combining this with Quan Yi's understanding of Du Gu Bo, he guessed the reason was likely his granddaughter.
Seeing Quan Yi stunned in place, Du Gu Bo said displeased, "What? This is a Title Douluo's promise. There are few things in this world that a Title Douluo can't accomplish. Moreover, I mean what I say. As long as it doesn't violate my principles, I can agree to anything."
The corners of Quan Yi's mouth slowly rose, and his heart was filled with joy.
He smiled and said, "This is what Senior said, so I won't be polite."
Seeing the not-so-benevolent expression on Quan Yi's face, Du Gu Bo felt a sense of foreboding, but the words had already been spoken, and he couldn't go back on them.
"Boy, you better think carefully. You only have one chance," Du Gu Bo warned uneasily.
However, the next moment, Du Gu Bo saw Quan Yi take out a peculiar device from his storage soul tool.
Immediately afterward, Quan Yi said to Du Gu Bo, "Senior, I've just thought of something I'd like to ask of you."
"So fast? Don't you want to think about it some more?" Du Gu Bo was startled by the speed of Quan Yi's decision.
Quan Yi shook his head firmly, "No need. I've already decided on this matter."
Seeing that Quan Yi didn't seem to be joking, Du Gu Bo said,
"Alright, speak."
"The thing I want to ask of Senior is very simple. I just want to share all research results related to the herb garden with Senior."
As he spoke, Quan Yi handed the device in his hand to Du Gu Bo.
"Research?"
Du Gu Bo took the device, puzzled, and said, "Is that all? Not to be modest, I actually know very little about this herb garden. Moreover, I'm not a specialized herbalist or physician. Most of my research revolves around poison.
Even so, you still want to make this request?"
Quan Yi said, "Of course, but my request has a key point. The research results mentioned here don't just refer to the past and present; they also include the future."
Quan Yi knew that Du Gu Bo would focus on solving his own problems next.
In this process, Du Gu Bo would have to research medicinal herbs.
This information would all be valuable assets, and Quan Yi couldn't miss it.
"The future… you're a greedy kid," Du Gu Bo understood that Quan Yi was planning to use him as his research staff.
Moreover, this term was for a lifetime.
However, this ultimately didn't violate his principles, and he could only nod and agree, "Alright, I agree."
Quan Yi nodded in satisfaction.
Quan Yi valued two things the most: strength and knowledge.
In terms of strength, Quan Yi himself didn't need Du Gu Bo's help.
That only left knowledge.
Therefore, Quan Yi used this only promise to gather knowledge.
Especially knowledge about herbs, which he was very lacking in. Now that he had Du Gu Bo, he could supplement this knowledge.
After Du Gu Bo agreed, he raised his hand to examine the object in his hand, asking curiously, "What is this?"
Quan Yi replied, "This is a gift I'm giving to Senior to help with your research.
Its name is a microscope. It's a research tool I specially prepared for you.
With it, I can guarantee it will be of great benefit to your research."
"Microscope? How do you use this thing?"
Du Gu Bo turned it over and over, discovering that its main body was a metal cylinder, but he didn't know what it was specifically used for.
Moreover, he had never heard of anyone researching medicinal herbs needing the help of a device.
Quan Yi smiled faintly and said, "Come, I'll tell Senior how to use this device."
Quan Yi reached out and took the microscope, then took out a small piece of transparent glass.
Immediately afterward, Quan Yi took out a small piece of jerky in front of Du Gu Bo.
Then, Quan Yi stretched out his finger, condensing his soul power into a knife, and cut off a thin slice of meat.
Beside him, Du Gu Bo, who was watching Quan Yi, was amazed by Quan Yi's delicate control of soul power.
This was pure soul power control. After the soul power left the body, it could still be condensed into a sharp blade. Not everyone could achieve this kind of operation.
This was different from soul skills. It required persistent practice to reach this level.
Quan Yi aligned his eye with the eyepiece and began to adjust the angle.
After adjusting, Quan Yi signaled Du Gu Bo to come to his side and observe.
"Come, Senior, take a look for yourself, and you'll know what it can do."
Du Gu Bo walked to Quan Yi's side and, imitating Quan Yi's actions, aligned his eye with the eyepiece.
When he saw the scene on the other side of the lens, even a powerhouse of Du Gu Bo's level let out a surprised sound.
"This, what is this?"
In the eyepiece, a pattern with dense and complex structures was displayed before his eyes.
Quan Yi explained from the side, "This is the piece of meat from just now, but this is the scene after being magnified hundreds of times by the microscope."
Du Gu Bo was no longer listening to Quan Yi's words. He was currently stunned there, observing with rapt attention.
After a long time, he slowly raised his eyes, astonished, "Microscope, truly living up to its name.
I never thought that the meat we usually eat would be so complex when magnified."
Du Gu Bo felt that his worldview had been impacted at this moment.
Even an extremely small piece of meat had such a complex structure.
"This is the research tool I'm giving to Senior. In the past, when researching medicinal herbs, people could only use the method of personally trying them to test their medicinal effects.
But with it, we can see its structure and effects in a more fundamental way."
This microscope was a high-quality product that Quan Yi had specially manufactured before coming.
Not only were the materials excellent, but the performance was also the strongest at this stage.
Du Gu Bo stared blankly at Quan Yi, and Quan Yi's unexpected actions caused a shock in his heart.
He had never thought that Quan Yi would have such methods.
After testing it, he could observe that this microscope wasn't a soul tool.
Moreover, the outer metal was still the most ordinary metal.
Just relying on these ordinary things, he could make such a magical thing.
Du Gu Bo had deep suspicions about Quan Yi's origins.
He didn't believe that a successor of an ordinary Soul Douluo family would have such peculiar things.
"I know this thing is very peculiar, but how exactly do you use it?" Du Gu Bo asked curiously.
Quan Yi said, "This microscope can see the structure of animals and plants.
With it, you can put a drop of your own blood into the lens, and then use some medicinal herbs to observe its specific effects on the human body.
In this way, you can observe the specific effects of medicinal herbs without harming your own body.
There are many uses for the microscope. What I've proposed is just the simplest method. Senior can study more uses on your own."
