After dinner, Ding Chen chatted with Ye Dai for a while, and looked at her tired, so he offered to send Ye Dai upstairs to rest.Unexpectedly, Ye Dai whispered with some apologies: "I still have to discuss tomorrow's arrangements with my father." ”Ding Chen then remembered that the apartment group of five usually met after dinner to exchange opinions and arrange the next day's work.It's just that there are too many things going on these days, and the five-person meeting has become irregular.It's rare that it's okay today, so the meeting will be back to normal.He could guess why Ye Dai felt apologetic.She has always felt that the construction of the waterwheel is due to Ding Chen, and for most of the people here in the apartment who don't know the truth, his experiment with the corn thresher should also be under the guidance of Ye Dai, at most Ding Chen is a person with more ability to act.So he stretched out his hand and gently patted the back of Ye Dai's right hand on the table, and laughed softly: "I have always supported you." ”Ye Dai smiled tiredly, but she didn't expect Ding Chen to suddenly reach out and touch her lips, and then quickly retract before Ye Dai could react.Ye Dai was suddenly ashamed, although the communication between the two of them last night was much deeper than this, and she almost ran to the Seine to see the Louvre.But this time is different from last night's rooftop, and there are still a lot of people in the restaurant.Ding Chen didn't give her a chance to blame herself, took her cutlery and sent it back to the bar, then waved at her from afar, turned around and went out.Ye Dai knew that he was afraid of being scolded, but he was always not good at chasing him to scold, so he had to sit on the seat and look at the people in the restaurant with a weak heart, and then soon found that no one paid attention to him, obviously Ding Chen's movements just now were too fast, and his position blocked the sight of most people, and the people in the restaurant either didn't see it, or they couldn't see what he had just done.Thinking about this clearly, Ye Dai put her mind at ease, picked up the water cup at hand and took a sip, and saw her father come over with a glass of water.He sat down next to Ye Dai and asked in a low voice, "How is the progress" Ye Dai took out a shiny copper-shelled bullet from his pocket and handed it over.Dad took it, looked at it by the light of the oil lamp on the table, and sighed: "Originally, I thought the oil lamp was also good, at least it was better than having a dark eye." ”"But that stupid guy made an electric light to light up our eyes," Ye Dai said helplessly: "Just now he asked me about the electricity consumption here in the past. ”"Really" Dad immediately became interested, and he said to Ye Dai: "Before eating, Ding Chen also told me that he planned to try to see if he could restore the power supply."
Do you think he can succeed" Daddy's question made Ye Dai feel very embarrassed.Like her father, of course, she hopes that Ding Chen can succeed and restore the light of the apartment.And she understands better than her dad what it means to restore the power supply to the apartment.But it is precisely because she knows the difficulty of this job very well, considering the personal relationship between her and Ding Chen, that she is unwilling to let Ding Chen carry such a heavy burden.After all, with Ding Chen's current contribution to the apartment, it can be said that he has gained a firm foothold, and he actually doesn't need to rely on radical methods to brush up his reputation.Ding Chen didn't know that the promise he casually gave could cause so much trouble to his father and Ye Dai.When he returned to his room from the cafeteria, he turned on his battery light and began to study the map and notes left by the unknown warrior.The battery light was displayed in the small dining room for a day, and after receiving countless praises, Ding Chen took it back.This reaction consumes aluminum and sulfuric acid.Since Ye Dai can make nitrocellulose cotton, it is obvious that concentrated sulfuric acid can be obtained here in the apartment, after all, Ye Dai needs concentrated sulfuric acid to desulfurize cotton.But since Ye Dai didn't let him promote this kind of battery, it means that the concentrated sulfuric acid in the apartment is not easy to come by and cannot be used for this consumption.So Ding Chen wisely did not apply to Ye Dai for the material.Since there is no way to open source, he can only find a way to throttle, so he continues to add distilled water to the battery to dilute sulfuric acid.After further reducing the concentration of the reaction solution, the amount of electricity generated by it was also reduced, and it has finally stabilized to the extent that it is just enough to supply an ED bead to light up.Ding Chen lifted the upper cover of the battery box and let the lamp head go down, restricting the light so that it could only be projected on the desktop.Then close the curtains, and it will be difficult to see the light inside the house from the window.Just now he asked Ye Dai about the power supply of the apartment in the past, and learned that the apartment was once powered by the power grid, and the power of the grid came from a wind power station on the mountain in the distance.The power station was supposed to supply the old town at the same time, but for some unknown reason, it was changed to supply only electricity to apartments, and it is said that after the apartments were converted into shelters, they were continuously supplied with electricity from this wind farm until they were suddenly interrupted a few years ago.But Ye Dai had never been to that wind farm, and the news she told Ding Chen came entirely from a paraphrase of what her father said.Ding Chen had read through the diary and found that the scavenger's attention had been focused on the old city.In the diary, the power station in Ye Dai's mouth was never mentioned.And the interest of this person should be more on the objects of personal life, and he should not care about this public infrastructure.Ding Chen was very suspicious that even if this person knew about the existence of that power station, he would not be interested in exploring it.Similarly, on that map, Ding Chen found no record of the location of the wind power station.In fact, if Ye Dai is right, then the hill where the wind farm is located should be outside this map.Despite this, Ding Chen still studied the map very carefully, after all, this is the only material that can provide an intuitive reference other than exploring it himself.From the map, he could at least tell the terrain he might pass on the way to the power station.I looked at the map for a while.Ding Chen felt a little sleepy, so he was about to get up and wash, when he heard a knock outside the door.Ding Chen felt very strange, at this time, the people in the apartment should have been asleep, who would knock on his door at this time He walked to the door, leaned on the cat's eye and looked out.The hallway was pitch black, and only a vague figure could be seen.He thought for a moment, opened the door, and immediately recognized that it was Rogge standing outside the door.Thinking of Rogge's hint to him today, Ding Chen's heartbeat couldn't help but start to accelerate.He stood by the door, and didn't mean to let Rogge in, and asked, "Is there something wrong" Rogge pursed his lips slightly, and did not take the opportunity to have an affair with Ding Chen.Instead, he asked directly: "I heard that you have a bow and arrow made by yourself" Ding Chen hesitated for a moment, and said to Rogge: "You have seen Zheng Yu" Many people know that Ding Chen has a bow and arrow that is used as a weapon, but there are not many people who know that he has the ability to make weapons.Ding Chen once admitted to Zheng Yu that the black knife was made by himself.Considering that other people don't have such a mouth, he guessed that Rogge heard the news from Zheng Yu.This kid's level of forgetfulness is really not covered.Of course, Ding Chen would not admit to Rogge that he supported Zheng Yu in pursuing him, so he had to ask knowingly.Otherwise, with Rogge's shrewdness, he would definitely be suspicious.Fortunately, Zheng Yu was not stupid enough to confess everything to Rogge, so Rogge didn't expect Ding Chen to know that Zheng Yu had dinner in her room.She was a little embarrassed to explain to Ding Chen that Zheng Yu took the initiative to bring her dinner."
Zheng Yu, this kid is good."
Ding Chen interrupted her words, nodded and said, "He's a warm-hearted. ”Rogge paused, looking relieved, she said to Ding Chen: "My archery skills are good, but the bow was broken by you before, so I want to make another one, can I ask you to help" Ding Chen thought for a while, and did not refuse directly, but asked: "What kind of bow do you want to make" Rogge's eyes lit up, and she asked Ding Chen: "Can I go in" She explained: "I want to see your bow first." ”Ding Chen couldn't help but hesitate.This big night let Rogge into his room.After it was passed out, it had to be explained to Ye Dai.But it seems that he has no reason to refuse, even if he wants Bo Fu, it can't be too obvious, so he took a step back, let go of the door, and motioned for Rogge to come in.Rogge smirked, walked into Ding Chen's room, and closed the door with his hand.aa2705221，，； mobile phone reading,
