Yang Xuan remembered that in the original plot, He Yu Zhu stole the tire of the third grandpa's bicycle because the third grandpa took his things and didn't do anything. He even sold it to a bicycle repair stall for a few yuan.
Coincidentally, the tire was later bought by Ran Qiu Ye. When she rode the bicycle to the courtyard, the third grandpa recognized it.
This incident left a bad impression on Ran Qiu Ye of He Yu Zhu. If it wasn't for this, perhaps Ran Qiu Ye and He Yu Zhu's relationship would have already been established.
But now the plot has been changed by his butterfly effect. Unexpectedly, Yan Bu Gui's tire is still missing.
The bicycle was found at the entrance of the courtyard. It seems that the thief stole the bicycle outside, then took a tire and left.
He Yu Zhu said to Yan Bu Gui with gloating, "Third grandpa, I think the thief had mercy on you. He only stole one tire. It's strange. The thief is too weird. He came all the way just to steal one tire? He could have easily taken the whole bicycle after unlocking it."
"You, you silly pillar! You'd be happy if my bicycle was stolen, wouldn't you?" Yan Bu Gui said angrily.
Yan Jie Cheng said, "Dad, actually silly pillar is right. If the thief came from outside, why didn't he steal the whole bicycle? Why only steal one tire? It's not normal. In my opinion, it must be an inside thief from the courtyard who has a grudge against you and stole your tire to teach you a lesson."
Yan Bu Gui said with a mournful face, "But I haven't offended anyone."
Yan Jie Cheng glanced towards the middle courtyard and was about to speak when Yu Li walked over, pulling Yan Jie Cheng away. "Let's go quickly. We won't get any work if we're late. It's impossible to find your father's bicycle tire anyway."
Yan Jie Cheng had to say, "Dad, don't worry. We'll figure out a solution together when we get back."
Yu Li pulled Yan Jie Cheng hard and walked a long way before saying, "What does it have to do with you? You won't be riding it anyway."
Qin Huai Ru watched the excitement for a while and went back home. She called out to Bang Geng. "Bang Geng, get up. You have to go to school later."
Bang Geng was groggy and rubbed his eyes with his hand, leaving a black oil stain on his face.
Qin Huai Ru quickly grabbed Bang Geng's hand and took a look. Sure enough, she found that Bang Geng's hand was covered in oil.
"Where did you get this oil?" Qin Huai Ru asked.
"I got it on the wrench." Bang Geng wouldn't admit that he stole anything.
Qin Huai Ru's face changed. She lowered her voice and asked sharply, "Did you steal the third grandpa's tire last night?"
Bang Geng panicked. "No, I didn't."
Jia Zhang Shi heard the commotion and walked over. "How can you be a mother like that? You're accusing your own child of stealing?"
"That's right, I didn't steal it." Bang Geng said.
Qin Huai Ru wasn't stupid. The oil on Bang Geng's hand was machine oil, and the oil on the wrench was kerosene. Yan Bu Gui often asked the first grandpa to bring back machine oil in small bottles from the workshop of the steel plant when he maintained his bicycle.
The workshop often had to lubricate the machinery with oil, and workers would often bring some home to lubricate their scissors, wrenches, and other tools. Even if the security guards saw it, they wouldn't bother.
Seeing Jia Zhang Shi coming out to protect her grandson, Qin Huai Ru stopped asking further questions, for fear of making too much noise and letting others know. She started searching in the house.
The Jia family's place was small, so there wouldn't be many places to hide a tire. Not long after, Qin Huai Ru found a tire under the bed.
"Bang Geng! Tell me the truth. Where did this tire come from? You're so small, how dare you do this? If the third grandpa reports it to the police, you'll be sent to a juvenile detention center!" Qin Huai Ru said.
"Why scare the child? Without any evidence, how can anyone send my grandson to a juvenile detention center?" Jia Zhang Shi said.
Everyone watched the excitement for a while and then rushed to their units because they had to go to work.
Yang Xuan naturally rode his bicycle to work today.
Yang Da Cheng didn't take Yang Xuan's car. "You go with Zhu. I'm used to walking."
"I'll buy you a bicycle when I get my hands on a bicycle ticket." Yang Xuan said.
Yang Da Cheng chuckled. "Then I'll wait for you to get me a bicycle."
He Yu Zhu was in a good mood today. "The third grandpa deserves it. He treats his bicycle like a treasure. I once needed to borrow his bicycle for something urgent, but he wouldn't let me. No one in the courtyard could borrow his bicycle. Now he's out of luck. Let's see if he's still bragging. Your bicycle is the newest in the courtyard."
"Who do you think stole the third grandpa's tire?" Yang Xuan asked.
"You don't have to think. It must be someone from our courtyard. Otherwise, why would they only steal the tire?" He Yu Zhu didn't say who it was specifically.
"Who do you suspect?" Yang Xuan asked again.
He Yu Zhu smiled. "It's most likely Bang Geng. The only one who could do this is him."
"I suspect you too. You don't get along with the third grandpa either." Yang Xuan said.
"Although I despise the third grandpa for being stingy, I don't have any grudge against him. Why would I steal his tire? I just want to date Ran Teacher now. Ran Teacher and the third grandpa are colleagues at the same school. I'd be an idiot to steal the third grandpa's tire at this time." He Yu Zhu said.
"By the way." He Yu Zhu said, "Be careful with your car. It might be targeted too."
After everyone went to work, Jia Zhang Shi went out with a bundle of mosquito nets.
"Where are you going with the mosquito nets?" The first grandma asked.
Jia Zhang Shi smiled. "The mosquito nets are torn. I'm going to the tailor shop to get them mended."
"You could just sew them yourself with needle and thread. Why waste money?" The first grandma asked in confusion.
"The tailor shop will sew them more securely." Jia Zhang Shi picked up the bundle and left quickly.
The first grandma looked at her several times. It seemed like there was something hidden inside the mosquito net.
Yang Xuan arrived at the factory and began to work on the technical renovation of the first workshop. This time was different from before. He could directly use the high-precision machine tools that he had modified before for processing, completing the task in one step and processing the required parts. Then he could assemble them directly.
Therefore, the progress was very fast. The time it took to complete the technical renovation of all the machines in the first workshop was not much different from the time it took to complete the technical renovation of the one machine before.
The task of processing the batch of high-precision parts for the ministry has basically been completed, so Yang Xuan could lead the technical renovation team to focus on the technical renovation of the machine tools in the first workshop. After completing a batch of parts, they would renovate a machine tool. The machine tool after the technical renovation could be used to process high-precision parts immediately. This way, the speed of technical renovation kept increasing.
