The eunuch's ears pressed against the hall gate and asked everyone to whisper, "The Dali Temple Minister and His Majesty are still talking, but they just can't hear clearly what they are talking about."

The guard then stood back.

He stood until the evening before Di Renjie came out.

Pei Xingjian went in and took a look at Li Chengqian's face, but Di Renjie's expression was very calm.

After leaving Ganlu Palace, Pei Xingjian followed Di Renjie's footsteps, "What did you say to him?"

"You are by Li Chengqian's side, wouldn't it be bad to run like this?" Di Renjie said as he walked.

"It's nothing big, I'm responsible." Pei Xingjian asked in confusion, "What did you say to Li Chengqian?"

"I said everything I should say, and I didn't say anything I shouldn't say." Di Renjie lowered his head and walked, "I know you are also very curious about some things about the teacher. The less you know, the better. I don't want you to be involved."

Walking out of Chengtian Gate together, Pei Xingjian sighed, "You are still close to the teacher. Although we are all students of the teacher, the teacher is always close to me, and only you, and the teacher has taken you since childhood."

"Actually, the teacher doesn't have much guidance," said Di Renjie. "Many times the teacher just gives me a direction."

"I understand." Pei Xingjian breathed the air in Chang'an.

"I'll go back first." Di Renjie and Pei Xingjian said goodbye.

After all, there was still a sense of distance. Pei Xingjian brought his loss back to his home, looking at the somewhat simple courtyard, and saw his wife with big belly hurried forward to support her, "How are you doing today?"

"Listen, the doctor said that I will give birth in half a month." Pei Xingjian's wife whispered, "I haven't eaten yet, I'll go and heat up the food."

"I'll do it myself." Pei Xingjian quickly asked his wife to sit down, "I'm going to have a rest soon. I won't go to court during this period and will accompany you to give birth to the child."

"What are you talking about?" Pei Xingjian's wife said again, "You have your own business, how can I delay you by myself?"

"It's okay." Pei Xingjian smiled and went to the kitchen to warm up the dishes.

Di Renjie returned home and went to Gu Qing's place after dinner. The door of the Gu family was very lively.

"Teacher." Di Renjie came to Gu Qing and said, "What are the teacher doing?"

Gu Qing put rubber on the piston inside the engine, "This is something that is cross-age."

Li Tai led the students from the academy to surround the engine, and was very excited. This was the first experiment. The students were still doing the last measurement of the engine, hoping that nothing went wrong.

"Are you okay?" Li Tai asked.

"It's almost done."

"Have the Mo family arrived?" Gu Qing asked Li Tai, "I said that the Mo family and the academy should compete with who will do it first."

"The Mo family members came to the news today and said they gave up." Li Tai said to Gu Qing, I will contact them today. Don't worry, I will definitely bring those people into the academy. We can't miss them."

Gu Qing nodded, although the Mohist craftsmanship is a bit behind the blueprint in his future, the Mohist inheritance must be kept, which is very important to the Central Plains.

The Mohist family pioneered the craftsmanship, which led to a step up the status of craftsmen. In the long history of the Central Plains, with the outbreak of war, the Mohist family disappeared in the Central Plains. Now, not to mention how useful it is to academies, it must be kept for their own selfishness.

"Try it." Gu Qing was ready and signaled that he could start.

A student began to shake the handle of the engine, and the entire engine began to shake as he was about to move. As the refined oil burned, the engine was filled with black smoke.

The handle is off, the engine is still rotating, the wheels below are not stopped, and the speed is also very stable.

"It's successful!" the students cheered.

The smell was a bit pungent, and Wu Mei hurriedly pulled Gu Xiao back to the house.

"Mom!" Little Gu Xiao looked up at Wu Mei and said, "I want to go and have a look."

"Let's see later." Wu Mei said, pulling her son.

Without manpower or animal pulling, the wheels turned on their own. Li Tai couldn't tell the situation, and the excitement in his heart was beyond words. Even he could see how much the engine was.

Gu Qing looked at the engine with a smile on his face. This was made from an old tractor in later generations.

The engine shaking became more and more intense, and the wheels stopped rotating.

The smiles on the students' faces disappeared, the engine trembled intermittently for two seconds before losing movement, but it still failed...

Gu Qing was already very happy, and it was very difficult to achieve this step.

“It should be a bearing problem.”

"Is the space in the inner cavity too small?"

...

The students who calmed down began to analyze the reasons and said to Gu Qing, "Mr. Hou, please give us another chance, I can improve it."

"No, don't worry, I'm very satisfied." Gu Qing nodded, "The scholarship will be given to you. This is a reward for you. Your name will also be written into the academy's records. You have succeeded. You can find the reasons for the engine slowly. If you can start, it means that you are not far from success."

These students who had just left the young felt embarrassed when they heard the words and felt ashamed of being felt.

"Go back, try to be better next time." Li Tai also comforted.

The students pulled the engine back to the academy.

"Hahaha!" Li Tai suddenly laughed, "Gu Qing, there is such a magical thing in this world, and it was made by our academy. I, the second person in the academy, benefited from it."

"In the future, this thing is used in many places." Gu Qing said again, "I'm afraid this thing will be taken away by people in the court."

"Why?" Li Tai was puzzled.

"You can also see that this thing can turn the wheels without pulling animals. What do you think is the first to affect it?" Gu Qing asked.

"Horse!" Li Tai answered immediately.

"By the way." Gu Qing said again, "There are many horse breeders in the Central Plains. If the engine is popularized..."

Li Tai thought backwards, "The horse-raising people will lose all their money, and there is a high possibility that chaos in the horse market will occur. The only way to stop the chaos in the court is to limit this engine to calm it down."

"Yes." Gu Qing nodded, "I have to popularize engines! I can start to prepare for work. I will go to the middle of the morning these days, and I will pave the road before the engines become popular."

"Okay!" Li Tai nodded, "I will stare at the engine that is the most perfect for doing things, and then echo you and spread the engine to all parts of the Central Plains."

The two looked at each other and smiled.

"Teacher." Di Renjie also said, "This thing can be used on a sea boat."
