I studied abroad in modern times

Senior Sister Zhang's home.

Senior Sister Zhang sat at the desk in the study, holding a pen in her right hand, writing something briskly on the paper.

In her left hand, she held the exercise book that Zheng Fa had submitted before.

She was not the only one in the study. Senior Sister Yuan stood beside her and kept talking, chattering with great energy.

Both of them looked relaxed, as if this was their way of relaxing in their spare time.

Senior Sister Zhang did not mean to complain about Senior Sister Yuan's talkativeness.

Senior Sister Yuan did not seem to need Senior Sister Zhang to respond to anything, but just kept talking about random things.

Suddenly, a question from Senior Sister Yuan brought Senior Sister Zhang back to her senses from the sea of ​​questions: "I heard that Senior Sister and Uncle Pang are still bargaining?"

"Yeah."

"How about you lower your terms?" Senior Sister Yuan frowned and suggested: "I heard that there are not many thousand-year-old purple bamboo tears now, and even Uncle Pang's disciples may not be able to get a share."

"No."

"What if Uncle Pang doesn't agree to you?" Senior Sister Yuan said with a pout.

"They won't disagree." Senior Sister Zhang seemed confident: "The longer it takes, the more likely they will agree."

"Why?"

"Because of Junior Brother Zheng." Senior Sister Zhang glanced at the handwriting on the exercise book and seemed to remember Zheng Fa's face: "He is very suitable for the "Taoism Foundation Building Method", more suitable than me."

Senior Sister Yuan nodded, as if she understood what Senior Sister Zhang meant: "You mean, they will be moved when they see Junior Brother Zheng's progress."

"Senior Sister Zhang, how long do you think it will take for them to agree?"

Senior Sister Yuan asked curiously.

"Uncle Pang's lineage..." Sister Zhang's tone was a bit complicated: "They like to use the Dongxu Spirit Eye to look around - that Junior Brother Sun, I'm afraid he is still squatting near Junior Brother Zheng's house."

"Hee, how would they know? I can't hide these from you."

"You have experience after being watched for a long time. If the top beam is not straight, the bottom beam will be crooked." Sister Zhang cursed expressionlessly.

"Sister, aren't you going to cheat Uncle Pang? How long will they watch?"

"At most ten days or half a month, Junior Brother Zheng's cultivation speed is not fake."

"...Sister is really confident in Junior Brother Zheng." Sister Yuan shook her head, as if she doubted that such a short time was not enough for Master Pang to make up his mind: "But I heard that Uncle Pang now cherishes the thousand-year-old purple bamboo tears."

Sister Zhang opened her mouth and was about to say something, when a golden talisman shot in from the window of the study.

She reached out to take it, and a voice with helplessness and reluctance came from the talisman: "Junior Brother Zhang, the thousand-year-old purple bamboo tears for two people have been prepared."

"You really predicted it, Senior Sister Zhang!" Senior Sister Yuan's tone was full of surprise: "Uncle Pang actually agreed!"

Senior Sister Zhang's tone was a bit complicated: "I didn't predict it, it was Junior Brother Zheng."

"Hmm?"

"The goods are too good, the price will be lower."

Senior Sister Zhang's face showed an expression that was not sure whether she was happy or unhappy.

...

When Zheng Fa walked into the study, Senior Sister Zhang and Senior Sister Yuan both looked at his face.

The inquiring eyes of the two made him feel uneasy.

"Junior Brother Zheng, have you gained anything from practicing the "Talisman Foundation Building Method"?

"I do have some understanding." Zheng Fa nodded, with a hint of hesitation on his face.

He really wanted to find an opportunity to discuss the so-called First Law of Bai's Talisman with Senior Sister Zhang-

It's necessary to discuss it.

This thing is purely derived through topology and computers.

Whether it really conforms to the Fu Dao system of the Xuanwei Realm, we still have to see the results of the experiment.

As for how to experiment.

Is there a better human laboratory than Senior Sister Zhang?

But he didn't know how to start.

After all, he had only received the "Fu Dao Foundation Building Method" for a month or two. He said that he had some ideas and wanted to borrow Senior Sister Zhang's body to do experiments?

Not to mention whether Senior Sister Zhang could believe that he had ideas in such a short time.

Just saying that using Senior Sister Zhang for experiments was a bit offensive.

No matter how much Senior Sister Zhang trusted him and how good she was, she was a Jindan Zhenren after all, and he was just a disciple who had just entered the door - the realms between the Xuanwei Realm were like natural moats, and Zheng Fa didn't think that Senior Sister Zhang had such a high tolerance for him.

Unexpectedly, Senior Sister Zhang actually took the initiative to find him today.

As if seeing the hesitation on his face, Senior Sister Zhang asked.

"Do you have any difficulties?"

"Senior Sister Zhang, I have some ideas - I need you to verify them." Zheng Fa thought about it and said with gritted teeth.

After all, this matter will be done sooner or later. Since Senior Sister Zhang asked about it today, it is a good opportunity.

"You say."

"Can I borrow your Yuanling Dao body?"

"..."

Senior Sister Yuan looked at Zheng Fa slowly on the side, and a sentence was written on her face: You are very brave!

Senior Sister Zhang looked at Zheng Fa for a long time, and seemed a little hesitant.

But she seemed to think of something again, and then nodded gently.

This made Zheng Fa stunned-does Senior Sister Zhang trust her discovery so much?

"What are you going to do?"

"I want to ask you for help to verify the five elements of some talismans."

It is actually very simple to see the correctness of the classification of the five elements of sub-talismans:

Just take the talismans classified according to the sub-talismans and bring them to Senior Sister Zhang for verification-to see if the classification is correct.

Senior Sister Zhang stood up, and a water-blue light flashed on her body.

A delicate and transparent human body appeared in front of Zheng Fa.

"Please take a look at the five elements of the Qingyun Talisman."

He saw a pair of lotus pedestals slowly condensed in Sister Zhang's dantian, and then the symbol on one of the lotuses slowly disappeared, and the symbol of the Qingyun talisman appeared on the blank petals.

It seemed that it didn't match the lotus very well, and the two lotus pedestals shook lightly at the same time and disappeared in Sister Zhang's dantian.

Sister Zhang didn't seem to be affected at all, but condensed another pair of lotus pedestals...

He finally understood how Sister Zhang determined the properties of the five elements talisman - the replacement method.

It's like you have a circuit board and a circuit component whose function you don't know.

In order to know what this component does.

You remove the components on the circuit board and then install this component - if the circuit board can work, you will know what this thing does.

If not, you remove another component and replace this component to try.

The only difference is - it's easy to break the circuit board if you do it this way.

Sister Zhang - it won't break!

"... Water."

Zheng Fa nodded, which was also in line with the judgment of the five elements sub-talisman.

"Golden Light Talisman."

"Earth Element."

"Armor Horse Talisman."

"Earth Element."

...

Zheng Fa was a little excited after finally finding a human laboratory. He tested hundreds of talismans in one breath.

The results all met the classification of the Five Elements' sub-talismans.

Just as he was about to make further efforts and continue the experiment, he felt his clothes being pulled.

"Huh?" He looked back at Sister Yuan who was pulling his clothes, puzzled.

"..."

Senior Sister Yuan didn't say anything, but pointed her finger upwards, motioning him to look at Sister Zhang's face.

Zheng Fa turned around and found that although Sister Zhang's face was transparent, the arc of her mouth was very flat, as if she was pursing her lips in anger.

He looked at the sky outside, and his heart sank again.

When he came, the sun was still hanging overhead, and now it was almost setting.

Sister Zhang was too useful as a tool, and he had too much fun.

He couldn't help but lose some of his respect for Sister Zhang.

The experimental equipment had to be cooled and rested after being used too much.

How could Senior Sister Zhang not have any objections when she was commanded by him like this?

Moreover, there was a huge gap between their status, and Senior Sister Zhang was a peerless genius.

Probably, she had never been commanded like this before.

Zheng Fa looked at Senior Sister Zhang, and then looked back at Senior Sister Yuan.

Senior Sister Yuan took two steps back, a little further away from him, with a look on her face as if she was afraid of blood splashing on her.

Disloyal!

"Anything else?"

Senior Sister Zhang's tone did not reveal any emotion, but Zheng Fa did not dare to go too far, and immediately replied: "No more!"

"Tell me what you were doing just now?"

Zheng Fa heard that there was anger in Senior Sister Zhang's tone, but she was still suppressing it.

"Junior brother is verifying a conjecture." He lowered his head and whispered.

"What conjecture?"

"The five elements of the talisman are determined by the five elements sub-talismans."

Zheng Fa picked up the pen on the desk and drew the appearance of the five elements sub-talismans on the paper.

"Five elements, sub-talismans?" Senior Sister Zhang slowly frowned.

"Yes!"

Zheng Fa drew a water element on the paper: "Sister, look, does this part look similar to the water element sub-element?"

He drew another gold element: "Here, it's the gold element sub-element."

"Wood element sub-element."

"..."

Zheng Fa analyzed each element one by one, and circled the existence of the five element sub-element on each element.

Sister Zhang seemed to gradually understand what Zheng Fa meant. The anger on her face gradually disappeared, replaced by a pair of bright eyes.

"You just..."

"I'm verifying this classification method."

"What's the result?"

"All correct!" Zheng Fa put down the pen, touched his head, and explained: "Junior brother is just obsessed with verification, not disrespecting you, sister."

Sister Zhang nodded gently, still didn't speak.

"Also, Senior Sister, these five elements are originally one, but when I used the "Talisman Foundation Building Method" to condense the Yuan Fu, I found that the Earth and Gold sub-symbols did not fit completely."

"One?"

Senior Sister Zhang heard this and looked at Zheng Fa suddenly, as if she had thought of something.

Zheng Fa drew the appearance of the five elements after the sub-symbols were combined on paper.

"..."

Senior Sister Zhang looked at the pattern in silence for a long time before she said softly: "You can be disrespectful."

"Ah?"

Zheng Fa was stunned.

"If you have such a discovery - you can be disrespectful."

He looked up suddenly and looked at Senior Sister Zhang.

He had never seen such a smile on Senior Sister Zhang's face.

This kind of wanton, proud smile.

Or in other words, a smile that is no longer high and mighty, no longer pretentious.

Zheng Fa was pleasantly surprised in his heart-

Just think about it, a genius of the Hundred Immortals League, a Yuanling Dao body.

It can be called a world-class laboratory with top-notch equipment.

You can do whatever you want!

This is the dream of a scientific researcher!

Senior Sister Yuan on the side blinked her eyes and suddenly said, "I want to play with your body, too!"

"?"

Zheng Fa felt that Senior Sister Zhang's smile froze and her expression seemed to become hesitant.

What a bird's beak!
