"Try it, just try it." Di Renjie raised his head a little unconvinced, looked at Tang Shanzhi and said, "The teacher said that if you learn arithmetic well, you can go all over the world." ”

"Hehe......" Tang Shanzhi was amused by Di Renjie's serious expression, and didn't argue with him too much, just beckoned to him and led him to the outside of the office.

"Uncle Shanzhi, where are we going?" Di Renjie followed behind Xiao Tang and asked as he walked.

Tang Shanzhi smiled mysteriously: "Take you to see something." ”

"See what?" Di Renjie continued to ask inquiringly.

"You'll know when you get there." Tang Shanzhi didn't explain too much, just took Di Renjie and his twin brothers to a factory that was constantly making loud noises.

……

Half an hour later, Tang Shanzhi and his entourage got out of the carriage and came to the production base of the Research Agency located outside the city, only to see countless huge and tall factories lined up, and all kinds of sounds came from those factories.

Xiao Tang didn't stay in the factory for too long, and after checking his identity, he took Di Renjie into a small factory casually, and saw countless craftsmen wearing uniform clothes and keeping their heads down, ignoring Tang Shanzhi and others, so they didn't see them come in at all.

"Uncle Shanzhi, what are they doing?" Di Renjie had never come to the production base of the Research Agency, and he was very curious about everything he saw, and found that he couldn't understand what those craftsmen were busy with, so he immediately asked Xiao Tang.

However, Xiao Tang didn't answer his question, just smiled and said, "That's exactly what I want to ask you, do you know what they're doing?" ”

"This, how do I know, I've never been here." Di Renjie was stunned by what Xiao Tang said, and replied without thinking about it.

"But you have knowledge, you can think about it, think about what the parts they have in their hands." Tang Shanzhi had already put away his smile at this time, and said in a very formal tone.

"This ......, how can this be imagined." Di Renjie was a little depressed, in his opinion, Tang Shanzhi was difficult to strengthen.

Tang Shan saw that Di Renjie couldn't answer his question, shook his head and continued to ask, "Xiaojie, I don't know if you heard a word from your teacher. ”

"What word?" Di Renjie asked.

"Mouth cannon party!"

"Uh......" Di Renjie's face instantly became much more ugly, although he had indeed not heard this word from Li Chengqian, but with his intelligence, he could understand the meaning of this word.

However, Tang Shanzhi did not stop hitting Di Renjie because of his ugly face, gently patted him on the shoulder, took him out of the factory, and came to a quiet corner before he stopped and said: "Di Renjie, you are very smart, at least smarter than me, but being smart is not everything. ”

"Uncle Shanzhi, what exactly do you want to tell me?" Although Di Renjie was not happy in his heart, reason told him that Tang Shanzhi was by no means untargeted, and the reason why he was brought here must have other purposes.

"Clever boy!" Tang Shanzhi shook his head with a faint smile, smacked his lips and said, "But although you are very smart, I still don't agree that you can be in charge of the development of the ironclad ship." Speaking of this, Xiao Tang paused, raised his hand and made a silent gesture: "Don't talk first, listen to me finish speaking, if you think it's unreasonable, it's not too late for you to refute!" ”

"Hmm!" Di Renjie nodded and swallowed the question that had already rushed to his mouth.

And Xiao Tang said: "Xiao Jie, do you know Zhao Kuo? ”

"Yes!"

"Do you think he's smart?"

"Very smart."

"Then why do you think he failed?"

"This ......" Di Renjie paused, as far as he knew, there were many reasons for Zhao Kuo's defeat during the Warring States Period, but Tang Shanzhi's question was obviously not in the answer known to the world, which made him a little embarrassed.

But fortunately, Tang Shanzhi did not force him to answer, and when he saw that he was silent, he continued: "The reason why Zhao Kuo failed was that his knowledge was obtained from books, he didn't know what the real battlefield was like, and he also didn't know that the morale and combat effectiveness of soldiers were not simply added or subtracted, and his ignorance of reality was the reason for his failure." ”

"This, I know everything." Di Renjie suddenly discovered that in fact, he knew everything Tang Shanzhi said, and if he was allowed to say it, it would definitely sound better than what Xiao Tang said.

But Xiao Tang didn't pay attention to him, just glanced at him lightly and said, "Don't you think you are no different from Zhao Kuo now?" ”

"What, what?" Di Renjie was suddenly stunned, he never expected that one day he would be compared to Cheng Yuekuo.

"Xiaojie, you don't know what it takes to build a ship, you don't know what difficulties need to be overcome in the manufacture of a warship, and you don't even know how many materials are needed to build a warship, so why are you responsible for the development of an ironclad ship? If nothing else, you know the watertight cabin, but do you know how to plug the leakage of warships? ”

"No, I don't know!" Di Renjie shook his head, and suddenly, he realized that it seemed that what Tang Shanzhi said was not wrong.

Theoretically, he could calculate a lot of things with the knowledge he learned from Li Chengqian, but in reality, he didn't know what he calculated looked like.

He could calculate how much space a battleship's watertight compartment needed and where it needed to be placed, but he really didn't know how the watertight compartment was sealed.

In the same way, Di Renjie found that if he considered the problem from reality, he didn't know much about a warship, whether it was the material or the structure.

"How? Boy, are you still so confident in yourself? As the saying goes, you don't need a hammer to ring the drum, Xiao Tang saw that Di Renjie stopped talking, and he also knew that he realized the key to the problem.

"Uncle Shanzhi, thank you!" Di Renjie lowered his head a little embarrassed.

At the end of the day, he's still just a kid, and it's inevitable that there will be some competitiveness when thinking about things, which is not a big deal.

If Xiao Tang hadn't woken him up, it was estimated that he would have planted a big heel on it before he realized what he was wrong.

But ......, but why didn't the teacher warn him when he came out? Di Renjie didn't think that Li Chengqian would be unable to think of a question that Xiao Tang could think of, and with deep doubts, Di Renjie asked Xiao Tang his own question.

"Your master is a human spirit, do you think he will easily do something to offend people?" Xiao Tang smiled bitterly, shook his head and said, "Now he is not what he used to be, a few years is enough time for him to grow into a qualified ...... Alas. ”
