After Xia Li entered the warehouse, he found a pile of charcoal from the corner, put it into a bag, added a few handfuls of salt, and threw it on the ground.
The special relief of “pop, pop, pop, pop!”
Chen Wenwan, who was reading in the room, didn't know that Xia Li was back. She was startled when she heard a particularly loud noise from the warehouse.
I hurriedly came out to check and saw my roommate throwing a sack to the ground as if he was suffering from "bipolar disorder" to vent his emotions.
Chen Wenwan paused subconsciously, her whole back was a little stiff, her body remained motionless, her head tilted slightly, and she looked at Xia Li pretending to be calm.
"Sister, what are you doing?"
She knew that this sister must have been stimulated by going to the countryside, and it would be normal if she really had any quirks.
But if he smashes things like this every day in the future, should she pretend that he didn't see him, or should he prepare more things for her to smash?
Xia Li turned around after hearing this and saw the cold beauty standing at the door, looking at her with a complicated expression.
Xia Li lowered his head and glanced at the sack in his hand, then raised his head at Chen Wenwan.
"Do you want a light?"
When Chen Wenwan heard this, her eyes became a little brighter, the corners of her mouth curled up slightly, and she said without any politeness: "I think.
What do you need me to do? "
Xia Li simply gave up and handed the sack in his hand to Chen Wenwan, "Grind the charcoal inside into powder."
Chen Wenwan didn't hesitate, she reached out and took the thing away.
"Okay, I'll give it to you later."
After a while, the warehouse once again heard the sound of "Pah! Pah! Pah!" A very decompressing sound of beating.
After Xia Li assigned the work, he went to the kitchen to mix a large basin of salt water, took it back to his room, and closed the door tightly.
A large basin of salt water was placed on the table. Xia Li stretched out two fingers into the water, acting as positive and negative poles and began to release supernatural powers.
Before this time travel, Xia Li would never have dreamed that one day he would use his ability to hunt the zombie king and go to a strange era to electrolyze hypochlorous acid with salt water just to make a few dry batteries. .
A large basin of salt water bubbled up with her electric shock, and soon a basin of hypochlorous acid solution was generated.
Chen Wenwan had also knocked the charcoal into powder. When she walked outside Xia Li's room, she saw the door was closed.
Although she was a gossip, she was not a troubled person. Seeing that Xia Li's door was not open, she just walked to the door and knocked.
He raised his voice and said, "I've polished it, will I leave it at the door for you?"
When Xia Li heard the sound outside the door, he walked out holding the basin of sodium hypochlorite and raised his chin towards the warehouse behind Chen Wenwan.
"Go there and fix it so you don't get it everywhere."
Chen Wenwan had no objection. She glanced at the large basin of liquid in Xia Li's arms, turned around and carried a large bag of charcoal powder into the warehouse.
The two looked around in the warehouse and found two bamboo tubes.
Xia Li poured the charcoal powder and hypochlorous acid solution into the bamboo tube in the ratio of three pounds of charcoal powder to five hundred milliliters of hypochlorous acid solution, and mixed them together.
He took another lid and covered it symbolically.
Chen Wenwan had never seen this thing before and was a little confused, "What is this for?
I thought you would get a generator and put it in our yard. "
Xia Li: "Dry batteries, but they need to be soaked for four or five days first."
As she spoke, she looked helpless, "I also want to get a generator, but the generator requires energy to operate.
Our current engine can indeed be used as power, but it is not safe to burn firewood every day, and we cannot always get up in the middle of the night to add fuel to the fire.
When I get up in the middle of the night, there is no light in the dark sky, so the light loses its effect. "
Today's technological level is not high at all. It is estimated that the principle of solar energy has not been developed yet.
Otherwise, if she can get a solar panel, she can directly build a solar generator, which will definitely be done once and for all.
Chen Wenwan didn't quite understand Xia Li's words about energy and energy, but she knew about batteries.
When he heard that Xia Li was going to use the package of toner and a basin of unknown liquid to make a battery, he looked at Xia Li as if he were looking at some kind of scientific madman who had escaped.
"You can't really come from some scientific research institute, right?"
Xia Li:? ? ?
