Liu Buqun and Wan Heming were banging around the iron stove, and they hadn't noticed Jin Feng coming until now.

Jin Feng didn't care and walked straight to the iron stove.

I saw a crankset on the chopping board next to the iron stove. Liu Buqun was responsible for forging the iron, and Wan Heming was responsible for fixing the crankset with pliers.

It was only then that the two finally discovered Jin Feng.

"Master, when did you come back?" Wan Heming threw away the pliers and asked in surprise.

"Mr. Jin!" Liu Buqun also put down his hammer and greeted Jin Feng.

"What are you doing here?" Jin Feng asked.

"We're making bicycle cranks!"

Wan Heming excitedly explained to Jin Feng: "Mr. Liu and I discovered that even if a bicycle is not pulling anything, it will be very difficult when going uphill. One time when I was repairing the winch, I suddenly thought, is the bicycle also the same?

Like a winch, can different sizes of chainrings be used to reduce the difficulty of going uphill?

Then I discussed this matter with Mr. Liu and Mr. Zuo. We all thought it was feasible, so we tried to make several different cranksets.

Master, Master, what do you think? Is it feasible?"

"Doable, very doable!"

Jin Feng rubbed Wan Heming's head: "You are doing well, Master supports you!"

The transmission chainring was very common on Jin Feng’s previous bicycle. On the way back, he saw the bicycle climbing a hill. Jin Feng also thought about this problem. However, with the existing technology in Xihewan, it is still very difficult to make a transmission chainring.

, even if it is really made, the cost will be very high, and even the transmission system alone is more expensive than the bicycle itself, so Jin Feng put this matter in the back of his mind and decided to wait until the technology develops for a period of time before doing it.

this matter.

When he came back, he found that Wan Heming had gone with him and had already begun to take action.

Wan Heming is indeed very talented in mechanics and has very strong execution ability. When he came up with the idea, he went to Liu Buqun and Zuo Zhiyuan to discuss it, and then he started to do it.

With talent and strong hands-on ability, coupled with Jin Feng's guidance and the laboratory provided, it would be difficult for Wan Heming not to leave a mark in the history of Dakang.

Jin Feng was very satisfied with Wan Heming, and rubbed his head again to encourage him: "If you have an idea, just demonstrate it and experiment it. You did a good job, and Master supports you!"

"Thank you Master," Wan Heming saluted to Jin Feng, and then said, "But can you discuss something with Master? Master, please don't rub my head in the future. If anyone sees me, it will be a joke!"

Before Jin Feng had time to speak, Wan Yuhong who was behind him was reluctant at first, went up and slapped Wan Heming on the head, then twisted his ears: "Sir, why are you rubbing your head?"

"Nothing, nothing, sister, please let go!"

Wan Heming jumped and slapped Wan Yuhong's hand.

Wan Yuhong didn't care about him at all, and continued to apologize to Jin Feng by grabbing his ears: "Sir, the child can't speak, don't be angry, you are the master, you should beat him and scold him!"

"Okay, okay, let go now."

Jin Feng couldn't laugh or cry and said: "It's a good thing for children to know that being shy means that our little Heming has grown up."

Hearing Jin Feng say this, Wan Yuhong let go of his hand and curled his lips and said: "What are you growing up? Yesterday, a toad entered the house. It was so frightened that it screamed and insisted on sleeping with me..."

"Sister, stop talking!"

When Wan Heming heard that his sister was going to say something embarrassing about him, he quickly reached out to cover Wan Yuhong's mouth, but Wan Yuhong slapped him open.

Wan Yuhong said in disgust: "Your hands are covered with putty, don't touch me!"

Liu Buqun laughed out loud at the siblings' play, and Jin Feng's mood improved a lot.

Wan Heming was worried that his sister would continue to embarrass him, so he quickly picked up the unfinished crankset with pliers and asked Jin Feng for advice.

Although Jin Feng understood Wan Heming's careful thoughts, he still motioned for Wan Heming to put the tooth plate on the table.

Then Jin Feng, Liu Buqun and Wan Heming started discussing around the tooth plate.

The structure of the crankset is not complicated. Jin Feng explained it to Wan Heming without the help of drawings.

Later, Jin Feng extended the discussion from the crankset problem to the gear ratio problem, and did not leave the iron smelting workshop until it was almost dark.

Wan Heming and Liu Buqun did not come to see Jin Feng off, but stayed in the laboratory, preparing to work overtime overnight to verify what Jin Feng just said.

Doing scientific research requires this kind of research spirit, and Jin Feng was very satisfied with the two of them.

Coming out of the iron smelting workshop, Jin Feng originally expected to see the hammer at first sight, but who knew that the first person he saw was Wei Datong.

Jin Feng didn't know whether he was passing by or coming to see him, so he asked: "Master Wei, are you here to see me?"

"Yes," Wei Datong saluted to Jin Feng: "I have something I want to ask sir."

"Mr. Wei, it's not the first day you've met me. If you have anything to say, just say it. Don't ask for anything."

"Then let me tell you straight," Wei Datong said: "I heard that your second batch of large ships in the East China Sea will be built soon. I would like to ask you to get a few ships first."

"What do you want the building for?" Jin Feng asked.

"Transporting grain," Wei Datong said, "Mr., must you have forgotten that I am the transport envoy of Xichuan..."

Wei Datong has been responsible for the construction of Dujiangyan and canals in the past two years. After hearing what he said, Jin Feng remembered that his old job was as a transshipment envoy of the Transshipment Department, specializing in transshipment of grain.

In the past, the tax grains collected by local governments were collected and sent to higher-level departments. Now, the grains shipped from the south of the Yangtze River and the kelp shipped from the East China Sea are sent to various county-level grain depots. In the event of a grain shortage, they can be dispatched as quickly as possible.

Disaster relief.

After the Ninth Princess came to power, she couldn't find more suitable personnel for a while, so she asked Wei Datong to continue working on grain transshipment and raised his rank.

It's just that Wei Datong has worked in the Transshipment Department for so many years, and he is already familiar with all aspects of grain transportation, so he put most of his energy into Dujiangyan and building canals, and most of the work of the Transshipment Department was handed over to his deputy.

, only when the deputy is unsure will he go to Wei Datong for instructions.

Wei Datong was very familiar with this job. There had never been any problems since he took over, and he never asked Jin Feng for help, so much so that Jin Feng even forgot about his position.

"Master Wei, haven't I already given you a batch of building ships before? Why do you want more?" Jin Feng asked.

After the first batch of flat boats were built, except for two for Zheng Chiyuan and one for the Jinchuan Chamber of Commerce, the others were used to transport kelp and grain.

This is the essential work of the transshipment department, so the bulk ships are nominally owned by the transshipment department.

"Sir, I have given you a batch, but it is not enough," Wei Datong complained: "His Majesty just talked to me and criticized the forwarding department's work progress for being too slow, but there is nothing I can do."
