"Why, why?" Xiao Tang's brain was stunned by what Li Chengqian said, and all the previous excitement disappeared.

"No why, let you get it, you can get it, don't get this out, beware of your title." Regarding the laws of physics, Li Chengqian did not think that Xiao Tang was a qualified listener, and it was better to tell him about this than to a cow, at least although the cow could not understand it, it would not ask so many whys.

Tang Shanzhi was obviously not the first time that he had been threatened by Li Chengqian with a knighthood, and after listening to his orders, he just let out a simple oh and prepared to get up and leave.

"Wait, take that kid Di Renjie with you," Just as Xiao Tang was about to leave, Li Chengqian stopped him and handed over a little guy to him.

"He? What are you taking him for? Tang Shanzhi looked at the black boy who was called out of the study by Li Chengqian with some depression, and his eyebrows were almost twisted into a pimple.

"It's useful, so you can take it with you." Li Chengqian did not explain the reason for letting Tang Shanzhi bring Di Renjie, and after giving him a perfunctory sentence, he pulled his apprentice to teach him face-to-face, until the apprentice nodded again and again, indicating that he understood, and then let Di Renjie out.

……

For Di Renjie, Tang Shanzhi still knows that Li Chengqian's proud protégé is often praised by Xiao Li as a prodigy.

So after leaving Daming Palace, Xiao Tang immediately grabbed Di Renjie with a fierce look: "Boy, say, what did your master ask you to do with me?" ”

"Let me help you do the math, Master said you are too stupid." Di Renjie looked up at Xiao Tang fearlessly, his eyes were looking at a fool, and the helplessness in it made Tang Shanzhi have an urge to beat people.

However, in the end, he still didn't get started, not because Di Renjie was cute, but because he really couldn't understand what this kid was talking about, what volume, what mass, what friction coefficient, God knows what it was.

But fortunately, Li Chengqian just gave these things to Di Renjie, as long as there is this kid, the above mentioned ones don't need him to participate at all, that is to say, when you get to the test ground, as long as everything is done according to this kid's orders, everything else will be solved by this kid.

However, despite this, Don Jr. underestimated how troublesome this trial would be.

The 100,000 catties of bricks and stones have been moved around by a group of people no less than dozens of times, and Di Renjie still takes the trouble to stand aside and record some things.

"Boy, what are you memorizing, why do you know every word, but you can't understand it when you put it together?" Three days later, Tang Shanzhi rubbed his nose and came to Di Renjie, who kept sketching with a small notebook.

Di Renjie turned his head and didn't answer Xiao Tang's question, but just grinned: "Uncle Shanzhi, do you believe it or not, if I let them move it again, your steam turbine won't be able to drag these bricks and stones?" ”

"Can't drag? No way, you've been here for three days and you should know it's impossible. Tang Shanzhi looked at Di Renjie, who was quite confident, and pouted and said.

"What I said is true! Why don't we bet? Di Renjie has become familiar with Xiao Tang in the past few days, and he speaks a lot more casually, and he does not have the slightest fear because of Xiao Tang's black face.

However, to Di Renjie's great surprise, Xiao Tang was cowardly, shook his head and said: "If you have something to say, let it go, don't learn from your master." ”

Di Renjie shook his head like a little adult and sighed, although he didn't know how many times his master Li Chengqian had deceived Xiao Tang and them, but when he saw Xiao Tang's appearance, he also knew that it was impossible for him to succeed in fooling him.

"Tell me quickly, what is the purpose of your kid, why do you say that Lao Tzu's steam turbine can't drag those broken stones."

"Actually, I said that Uncle Shanzhi, you can't know, anyway, the results will come out in a while, you can see for yourself."

Di Renjie, like Li Chengqian, also didn't want to explain physics to an 'illiterate', so he rightly rejected Xiao Tang and just let him see the final result.

And it turns out that what Di Renjie said is not wrong, when the legendary omnipotent steam turbine exerts its force again, it really does not drag the stacked stones, no matter how hard the person who operates the machine, how to adjust it is useless.

Xiao Tang was stunned when he watched from the side, everything in front of him made him not believe his eyes no matter what, what could be dragged in countless experiments in the past three days, but now it can't be dragged, is there any demon magic in this?

Just when Xiao Tang didn't know how many times he rubbed his eyes, Di Renjie had already come to his side and gently pulled the corner of his clothes: "Okay, Uncle Shanzhi, my task is complete, we can go back." ”

"Go back?" Listening to the continuous roar of the steam turbine in the river not far away, Tang Shanzhi asked uncertainly.

"Yes, the things that should be counted have been calculated, so naturally you can go back." Di Renjie showed a big smile.

"What did you figure out?" Tang Shanzhi asked puzzled.

"We can build iron ships." Di Renjie turned around and walked towards the periphery of the test site, and replied in his mouth.

"Ahem......" Tang Shanzhi only felt that he seemed to have been really thundered, could it be that there was a problem with his eyes just now, and now there is a problem with his ears?

Xiao Tang, who couldn't figure it out, caught up with Di Renjie in a few steps and grabbed him: "Boy, what did you just say?" Iron ships? ”

"Yes, Iron Ship!" Di Renjie said.

", did you kid lie to Lao Tzu because Uncle Shanzhi hadn't read a book for a few days?" Tang Shanzhi finally determined what Di Renjie was talking about, and immediately felt that he had been fooled.

However, Di Renjie was a little disapproving, raised his hand and pointed to the top of his head, and said casually: "Uncle Shanzhi, if someone told you ten years ago that people can fly to the sky, would you believe it?" ”

"I ......" Tang Shanzhi found that he really had no way to answer the question raised by Di Renjie.

Looking at the glider that was constantly circling and patrolling overhead, Na Na said: "This, this is completely different, that one is in the sky, and now we are talking about it in the water." ”

"It's no different." Di Renjie, who was in his teens, put his hands behind his back and said as he walked: "What didn't exist before may not exist in the future, and the real ironclad ship may not be able to be built now, but one day in the future, it will definitely appear on the sea and guard the thousands of miles of the Tang Dynasty, and that day will not be far away." ”

That day won't be far away, will it really not be far away? Tang Shanzhi couldn't believe everything he heard.

But looking at Di Renjie's confident appearance, he couldn't help but believe it.

As the so-called building near the water gets the moon first, as a disciple of Li Chengqian, it is not a big deal to know some things that ordinary people don't know, maybe the man with the name of 'Zhi Demon' can really make the fine iron float on the water!
