But despite this, those people still seemed very excited, and they entered the Daming Palace in a hurry, and entered the East Palace after going around in a circle.

"Your Highness, great joy, great joy!" The fat waiter who had just sent the widow away ran back to Li Chengqian's study again, his tongue drooping outside, and he said breathlessly.

"What's the joy? Let's hear it. Li Chengqian was leaning back in the rocking chair and dozing, and squinted his eyes and asked after being woken up by the fat man.

"Your Highness, Lord Xiao Tang is here, and said that the one you asked them to study has been successfully developed." The fat waiter thought about it for a long time and didn't remember what Tang Shanzhi said just now, and his face suddenly became a little bitter.

But despite this, Li Chengqian still sat up straight from the rocking chair, stared at the fat waiter sleepily and said, "Where is Tang Shanzhi?" But gas turbines have been studied? ”

"Yes, yes, that's what Lord Xiao Tang said." The fat chamberlain nodded quickly, and said without a trace of hesitation.

"Go, let them in, hurry up, run two steps and die!" After hearing the news that the gas turbine had been studied, Li Chengqian could no longer be calm, jumped up from the chair, and saw that the fat waiter seemed to be running a little slowly, so he raised his foot and kicked his buttocks.

"Oops!" The fat chamberlain was kicked and stumbled, but he didn't dare to say more, his two short legs shook quickly, and he rushed out of Li Chengqian's courtyard like lightning.

In fact, the so-called gas turbine is not much different from the steam engine in principle, both are powered by steam, but the steam of the steam engine is directly applied to the cylinder, and the gas turbine is to spray steam to a runner similar to a fan, so as to achieve the purpose of pushing the rotor to rotate.

This kind of thing was generally widely used in power plants and shipbuilding in later generations, but it had only one role in Datang, that is, it was applied to warships.

After a while, Tang Shanzhi, Gong Yihan and Liu Min came together, and when they saw Li Chengqian, they immediately bowed: "His Royal Highness the Prince, Minister Tang ......"

"Excuse me, come here, come here!" Before the three of them finished saluting, Li Chengqian had already waved his hand and said urgently.

"Yes!" Tang Shanzhi knew what kind of temper Li Chengqian was, so he didn't be polite to him, arched his hand and walked to him and sat on the chair that had been prepared a long time ago.

The two old men, Gong Yihan and Liu Min, were a little uncomfortable, hesitated for a moment before walking over, and each found a chair to sit on, but if you look closely, you will find that these two old men are only sitting on half of their buttocks.

However, Li Chengqian didn't bother to care about these at this time, and immediately asked after the three of them sat down: "I just heard a report that the gas turbine has made progress, but is there such a thing?" ”

"Your Highness, it's true, and it's already been tested, now it's time to find a ship and load it with actual testing." Speaking of gas turbines, Tang Shanzhi immediately became excited, grabbed a chair and leaned back against Li Chengqian: "Your Highness, this thing is really not easy to do, you don't know how much effort we have ......."

"Okay, okay, I'll give you a lot credit for this matter, let's talk about the test first." Li Chengqian already knew that it would take a lot of effort to develop the gas turbine in Datang, so naturally he would not listen to Tang Shanzhi to talk about the difficulties.

And with his current position, he can completely ignore the research process and ask directly about the results.

After all, Li Chengqian's current situation is very different from before, and the old man's delegation of power has made him invisibly involved in many things, if he has to care about the process of everything, he is afraid that he will not be able to do it even if he is tired to death.

Tang Shan saw that Li Chengqian was indeed not interested in listening to the process in the middle, so he scratched his head in embarrassment, and his face showed a tangled expression.

Seeing him in such a state, a flash of realization flashed in his heart, and he patted Xiao Tang, who was close at hand, and said: "If you have time these days, go back and sort out a list of materials, list all the meritorious people who participated in the research, and the palace will reward them as appropriate." ”

After listening to Li Chengqian's arrangement, the three of them, including Gong Yihan and Liu Min, immediately smiled again, and Xiao Tang grinned and said: "Hehe, Your Highness's eyes are like torches, we thank Your Highness!" ”

"Alright, stop rambling, I'm about to die of you guys." Li Chengqian looked at the three guys who were in a hurry just now, but now they were procrastinating, and suddenly felt that the roots of his teeth were a little itchy.

"Hehe, Your Highness, this time we have made all preparations, including land tests and underwater tests, and guess what?" Tang Shanzhi said the first half of the sentence excitedly, and just when Li Chengqian was about to listen to the actual things, the goods began to sell again.

As a result, he was extremely happy and sad, and Li Chengqian showed an unkind smile on his face: "Tang Shanzhi, if you dare to say one more nonsense, Lao Tzu will demote you to a knighthood, and I will see how many levels you have in a county that are enough for me to demote." “

"Oh, don't, don't. I said, I said, can't I do it! ”

"One sentence!"

"Let's not talk about the test on land, we put the gas turbine into a box in the water test, and the result was that we successfully dragged a boulder weighing nearly 100,000 catties on land." Tang Shanzhi said very quickly.

With Li Chengqian's unobtrusive temper, Xiao Tang really can't be sure if he will really reduce himself to no quality, anyway, this kind of thing would rather be believed than not.

However, after Tang Shanzhi finished speaking, he found that Li Chengqian fell into silence for a long time and did not speak, and only after a long time did he slowly ask: "How did you calculate your 100,000 jin boulder?" What is the shape of the stone? ”

What shape? Tang Shanzhi was stunned for a moment, and said reflexively: "It's just to use some bricks and stones to pile them together!" ”

"......" Li Chengqian took a deep breath, and it was only at this time that he realized that he was about to die of talking about it that day.

Originally, he wanted to know the shape of the boulder and calculate the pull of the gas turbine, but now it seems that there is no chance.

You must know that according to the fixed rate of physics, after knowing the area and weight or volume of an object, the friction force can be deduced, and this friction force can also be converted into tensile force.

And if this value can be obtained, it is natural to calculate how much weight the existing gas turbine can propel in the water.

However, Tang Shanzhi, an illiterate person, did not have this concept at all, he only remembered the weight of the masonry, but did not remember to measure the area of the pile, so naturally there was no way to get the result by calculation.

Li Chengqian, who was helpless, could only sigh in the end, looked at Xiao Tang, who was still excited, and said: "You go back, go back and test again, remember this time, you must remember to measure the area of the stack, what is the total weight, understand?" ”
