[Then go one step further, establish the Internet, develop the Internet and mobile payment, and slowly reduce the circulation of paper money until it disappears.] The monks travel across borders, connect directly to the local network when they arrive at their destination, and automatically settle the exchange rate when they shop. However, the premise of this is that the construction of the Internet in the entire universe must be of unified standards, and there can be no one world that has an independent small region. 】

[As long as there is a place for my Ye family's old shop, don't think about an independent small area. Ye Zhou's words were bullish.

[The Ye family's old shop will not patronize the business of monks in the future, and increase the business of mortals, and unify the currency, there is no reason to divide monks and mortals. 】

[This has to be handed over to you, the large untouched realm of immortal sharing and mortal use is your strength. Ye Zhou shrugged at the candle on the table, [It's like if you get a call, I don't believe that the monks can continue to endure the use of fluorescent stones and candles for lighting. 】

[Tsk, having said so much, we still have to go back to the starting point, there is no electricity. 】

[I just worshipped so many ancestors and masters, and there is no revelation at all? There was a hint of a smile in Ye Zhou's voice.

[I think we should make a primitive voltaic battery first, using salt water as the conductive liquid, and see which metals can be discharged together.] Oh, by the way, it's not sure whether the salt water is a conductive liquid now, and the experiment happened to be done at the same time, if the salt water is not conductive, you have to find another conductive material. 】

[Only voltaic batteries, how do you check whether there is a discharge?] You don't even have an ammeter. 】

[Then add another Leyden bottle.] 】

[Okay, I'll give you a hand, do the experiment yourself, and tell me what materials you want.] 】

Lu Xiaoman's eyes lit up instantly.

[In exchange, you are not allowed to fall behind in any of your cultivation lessons, and you must not neglect one or the other, otherwise no matter how smoothly your experiments on the technology side are done, the spell side will be a mess, and the elders who support you now will be disappointed in you, you know what the consequences will be. 】

Lu Xiaoman nodded vigorously, [Know. 】

[Read the book, tomorrow's formation class, check if there is any omission in the homework. 】

[Hmm.] 】

Lu Xiaoman took out the books and notes of the formation, pulled out a chair and sat down to review it carefully.

The next morning, Lu Xiaoman rushed to the lecture hall after breakfast, Le Lun stood outside the door of the library with a teapot in one hand and a teacup in the other, looking as if he was basking in the sun.

Lu Xiaoman pursed her lips and smiled lightly, turned around and walked into her small classroom in the lecture hall.

Not long after he sat down, there was still some time before class, Kunyu Zhenren Yu Kun pushed the door in, compared to the previous times, this time his face was a little serious, with the majesty of Elder Jindan.

Lu Xiaoman pretended not to see Kunyu's real look, she calmly got up and saluted and said good morning.

Kun Yuzhen stood in front of Lu Xiaoman across the table, looking at her obediently saluting, her eyes widened, and she raised her hand to knock her chestnut, but when her hand fell, it turned into rubbing her head.

"If you are bullied and don't say anything, if it weren't for Le Lun's well-informed, would you plan to secretly take revenge one day?"

"I had the plan, but I didn't take action."

"There is no action, the female disciple who raised the snake will look for her this morning."

"That ......"

"You want to ask that Qin Jingyuan?"

"Well, will he be asked for questioning? The brothers and sisters who lived with him cared about him very much. ”

"Then it depends on whether Qin Jingyuan is looking for you."

Yu Kun remembered the picture of the audio-visual stone he saw yesterday.
