"Useless?" Kadel's face was a little unsightly. If it wasn't for Xiao Yi who was still standing by, he would have scolded him directly.

This is a good idea that he thought about for a long time, but the outsider actually said it was useless?

Although he himself is not sure whether it can be used or not, it hurts people to say it so bluntly!

Xiao Yi clearly saw Kadel's unhappy look, and immediately said: "Wang Gong, please tell me the situation of this part carefully."

Kadel looked at Wang Xingfeng with a bad look on his face, but he wanted to see if this person could say one, two, three!

Wang Xingfeng nodded, pointed to the blueprint, and explained it.

"This part should be used to improve the transmission efficiency of a certain machine, but this part is a bit taken for granted, look here..."

Wang Xingfeng continued to talk, Kadel was a little disdainful at first, but slowly his face became serious and serious.

As Wang Xingfeng's story continues to deepen, Kadel has transformed into a primary school student, constantly raising questions that he doesn't understand.

Under Xiao Yi's instruction, Wang Xingfeng knew everything and said everything.

"I see, it turned out to be like this!" Kadel's eyes lit up, "No wonder our machine is so slow!"

After sighing with emotion, Kadeer bowed his hands to Wang Xingfeng: "Wang Xingfeng, I want to worship you as my teacher, please accept me as my apprentice!"

Seeing Kadel's reaction, Wang Xingfeng was stunned for a moment, and then hurriedly said: "There is no need to be a teacher. We can discuss the mechanical issues with each other."

Kadel shook his head: "In front of you, I can only listen and ask questions, and I have no qualifications to discuss at all."

Xiao Yi laughed and said, "Apprenticeship seems too serious. In the future, Kadel can come over to ask Wang Gong more about mechanical issues. That's all right!"

Kader frowned slightly, and then replied: "That's fine, but I want to ask how this part can be modified to improve the transmission efficiency."

Wang Xingfeng thought for a while and replied, "Imagination is impossible without seeing the specific machine. Any part serves the whole. Even if we design a part with very high transmission efficiency, if it does not fit the whole machine , that's useless!"

"Well said, Island Master Xiao, help us move a mining machine!" Kadel hurriedly said to Xiao Yi who was beside him.

"Okay, I've become a tool man, wait!" Xiao Yi replied with a smile, then walked out, found the nearest island monument, traded back a mining machine, and then pushed him to Wang Xingfeng's side.

"Wang Gong, look, it's this kind of machine, I want to improve this part..." Cadel dragged Wang Xingfeng to the machine, pointed to a part, and said.

Xiao Yi saw that they were seriously studying the mining machine, and he had nothing to do here, so he quietly left.

Walking out of the machining factory, there was a loud noise in the distance, and Xiao Yi followed the sound.

"Why did you arrest me, is it not allowed to sail on the route?" A young man in his twenties said with his neck stuck.

The Yi Ranpin soldier on the side replied solemnly: "Allow, but as long as you enter our territorial waters, you must accept our inspection, please cooperate!"

"The territorial waters? The sea here is public. Which one stipulates that this is your territorial waters?" The young man asked rhetorically.

The soldier frowned, Xiao Yi walked up and patted him on the shoulder, the soldier looked back and saw that it was Xiao Yi, and immediately said respectfully, "Island Master!"

"Are you the head of this island?" The young man looked at Xiao Yi curiously.

Xiao Yi nodded: "Did you find it according to the coordinates, or did you just pass by?"

The young man replied: "Naturally, I passed by here. I just drove along the route. Who knew that your island was on this route!"

"In this case, then please leave, please don't do anything to make our soldiers misunderstood, otherwise if they hurt you, you will suffer." Xiao Yi waved his hand and motioned for him to leave.

Who knows that the young man replied: "Since you are here, you must have a tour here!"

Xiao Yi asked curiously, "Are you alone?"

"Of course, but I'm recruiting crew members, are you interested in joining me? I'm the man who wants to become the Pirate King!" the young man said excitedly.

"Well, come on, I'm not interested in a man who becomes a man!" Xiao Yi said helplessly, "Remember, there are only resorts on the island for you to play, other locations are not allowed to visit!"

After speaking, Xiao Yi turned around and left!

The young man was stunned when he heard Xiao Yi's words, and then he came to his senses: "I mean to be a man like One Piece, what kind of understanding are you, or the island owner!"

The soldier on the side said, "Let's go, I'll take you out."

The young man grumbled and left.

Kadel, Wang Xingfeng and others surrounded the mining machine all morning. With the joint efforts of everyone, they almost redesigned the entire machine.

During this period, Kadel was completely convinced by Wang Xingfeng and others.

Not only Wang Xingfeng, but also other outsiders here, just pull out one, and have richer theoretical knowledge about machinery than him.

Of course, in practice, Wang Xingfeng and the others are not as good as Kadel.

"If it is manufactured according to this design, this mining equipment will definitely surpass all mining equipment in the world!" Kadel said excitedly, looking at the equipment drawings they discussed.

Wang Xingfeng shook his head and said, "I can't say that, at least I know a mining machine that is countless times more advanced than this!"

Kadel was stunned for a moment, and said with a look of disbelief: "How is it possible?"

"The island owner has a mining machine that we cannot produce under our current conditions. The mining efficiency is definitely more than 100 times that of our newly researched mining machine!" Wang Xingfeng replied.

"Hundred times?" Kadel's eyes widened, "How is this possible?"

"I also feel a little unbelievable, but this is the truth. We used to have automatic mining machines in that world, but they couldn't reach the machine that the island owner took out!" Wang Xingfeng shook his head and said.

After Kader was shocked, his face was full of curiosity: "I must see the mining machine you speak of when I have a chance!"

"Don't worry, there is definitely a chance!" Wang Xingfeng said with a smile.

Kadel nodded and said, "Can I bring back a copy of the blueprint first?"

More than 90% of the credit for this blueprint is attributed to Wang Xingfeng and others. Kadel actually only provided a prototype for them to study!
