Yet Jiang Mianmian had no idea that her upcoming trip to Capital City was such a stimulus for Zhaodi.
At the moment, Jiang Mianmian was sitting on the back seat of a bicycle, discussing matters with her dad.
"Dad, let’s not go straight home later, you’ll accompany me to buy some things."
"What do you want to buy, my girl?" Jiang Changhai asked curiously.
"I want to buy some materials for making batteries." Jiang Mianmian never kept anything from her parents and spoke honestly.
"Batteries, you’re making batteries?" Jiang Changhai was somewhat surprised when he heard this.
"Yes, making batteries can reduce the cost of cakes." Jiang Mianmian explained simply.
"Alright, my girl, I’ll go with you to buy the materials first, where shall we go?" Jiang Changhai didn’t know what materials Jiang Mianmian needed, so he asked.
Ever since Jiang Mianmian successfully made a color TV, Jiang Changhai knew of his daughter’s abilities and fulfilled all her requests without a second word.
He was always serious about supporting his daughter’s creations.
Jiang Mianmian gave an address, and the father-daughter duo left Stone Bridge Village, heading straight for the designated spot.
The materials for making batteries were not bulky, so after they purchased them, Jiang Mianmian packed them all into her little backpack to bring back.
After dinner at home, she locked herself in her room and began to make a lithium battery.
Having practiced many times within the system, Jiang Mianmian almost developed muscle memory for these materials. After roughly two hours, she managed to create a rechargeable lithium battery in the real world.
After making it, she first tested the charging technology at home and, finding no problems, she excitedly ran out, eager to call Yu Cheng and share the good news with him.
Jiang Mianmian called, and it just so happened that Yu Cheng answered.
"Hello, Brother Yu, I have good news for you, I finally made the battery. I’ll bring it to you in Capital City the day after tomorrow to show you," Jiang Mianmian said excitedly.
Yu Cheng responded indifferently with a "Hmm," saying, "Alright, I’ll be waiting."
He had already known that if Jiang Mianmian said she would do it, she would definitely make it happen.
However, Jiang Mianmian forgot to tell Yu Cheng that this time she didn’t make a nickel-metal hydride battery, but a lithium battery instead.
So Yu Cheng only thought that Jiang Mianmian had increased the capacity of the battery as she initially said.
"Hmm hmm, it wasn’t easy, I worked on it for a whole semester. Now the cost of making cakes will go down, Brother Tang Lin will definitely be very happy," Jiang Mianmian said excitedly.
Yu Cheng: "That sly merchant, Tang Lin, knowing this, will definitely be over the moon about making more money."
"Pfft, Brother Yu, if Brother Tang Lin hears this, he’ll definitely want to take down your name in his little notebook again," Jiang Mianmian laughed, teased by Yu Cheng.
"Let him write, over the years, his book of grievances must have piled up," Yu Cheng said nonchalantly, caring more about when Jiang Mianmian would come to Capital City so he could notify the material supply department in advance.
"I’m thinking of heading over the day after tomorrow. I just got back from my hometown today. I’ll pack up tomorrow and can set off the day after," Jiang Mianmian planned.
"The day after tomorrow? Mianmian, when you come this time, don’t take the train, take a plane instead," Yu Cheng suggested after a thought.
Upon hearing that she could hitch a plane ride, Jiang Mianmian immediately cheered, "That’s great, thank you so much, Brother Yu!"
Taking a plane would only need two or three hours, while taking a train would take several days.
