After Lin Chunhong calmed down from the initial excitement, he saw the steam turbine driving the gears to rotate lazily and slowly, and suddenly realized: In theory, the energy utilization efficiency of multi-stage steam turbines is indeed higher than that of piston steam engines, but that is under ultra-high pressure. At present, due to the confined technology and materials, the pressure that the boiler can withstand cannot be too high, and its energy utilization efficiency is so low that it cannot tolerate it.

Therefore, it is necessary to be a piston-type steam engine that can be tried to make a practical steam engine. Several men sweated heavily and added coal, but they could only make the gears rotate slowly, which is a clear proof.

In other words, the emergence of the world's first practical steam engine will take a long time to wait.

Sure enough, Song Yingxing said from the side: "A steam engine is not as big as a mule. If Qin Wuchao really wants to use this thing, he will refuse it harshly."

Although Lin Chunhong was a little disappointed, he was not anxious at all. He smiled and said, "Although it is not practical, he has taken the first step after all. This alone is enough to write a lot. In the future, we have to take a two-pronged approach. On the one hand, we start from improving the pressure that the boiler and the trachea can withstand, and on the other hand, we have to focus on finding ways to improve efficiency under the current pressure."

Lin Chunhong accidentally said the concept of piston type directly. He felt that compared to the practicality of the steam engine, the exploration of the entire nation is more important. Perhaps his tips can help Song Yingxing and the others avoid detours, but what are the benefits of this in cultivating the exploration spirit of the entire nation?

Immediately afterwards, when Song Yingxing saw that Lin Chunhong was quite proficient in machinery, heat, etc., he was reluctant to introduce some of the techniques used in the steam engine.

Lin Chunhong nodded frequently, feeling relieved.

A steam engine is enough to show that the Academy of Engineering has accumulated a very high level of knowledge in mechanical and thermodynamics. For example, the self-closing valve is used in the boiler, which shows that Song Yingxing and his group of people are not weak at all. Perhaps, within ten years, they will really try to create a practical piston steam engine.

Lin Chunhong saw it with relish. Since he had arrived at the Academy of Engineering, Lin Chunhong simply did not rush to return to Jingzhou and inspected the Academy of Engineering to fully understand the current technical level.

Not to mention that Lin Chunhong took stock of his technical strength on Bailizhou Island, but also that Shi Kefa and Qian Qianyi and Qu Shishi met in Changshu and jointly planned a countermeasure, he suddenly received a report: Lin Chunhong abandoned his boat and rode back to Jingzhou as if his butt was on fire.

The three of them looked at each other, and thoughts arose in their minds: Could something big happened in Jingzhou and Lin Chunhong must return to Jingzhou to deal with it in person?

Especially Qu Shixi, his face flushed, stood up excitedly and said, "It must be a chaos in Jingzhou. As the saying goes, taking advantage of his illness to kill him. Without further ado, we have to move immediately!"

Qian Qianyi saw Qu Shisi's excitement and sighed in his heart: This disciple is good at everything, but the power is too strong. He has been waiting for so many years. Can't he find out what happened in Jingzhou before making a plan?

Qian Qianyi shook his head and said, "I have fought with Lin Chunhong for so many years. I have failed the previous few times and have a chance to turn the tables. If I fail this time, I may even lose all my capital. Be cautious."

Shi Kefa also said: "A rash move has been a taboo since ancient times."

Qu Shisi sat down dejectedly, regretting the recklessness just now, and blushed, saying, "From the discussion between Mr. and Lord Shi."

Seeing that Qu Shixi realized his mistake, Shi Kefa did not bother him, and said with a sigh: "The key to Jiangnan just now is the word "water". Lin Chunhong relied on dozens of centipede ships to openly take advantage of Jiangnan for himself, and only then did he have the strength today. I believe that the key to breaking the situation is water: to train the naval army and expel Lin Chunhong's Yangtze River Navy, he can uproot Lin Chunhong's power from Jiangnan."

Qian Qianyi said: "It is reported that Lin Chunhong has three naval fleets, with more than 100,000 troops and more than 100,000 castle-like warships. How can we beat him if we are more than water forces?"

Shi Kefa said: "Mr. Muzhai doesn't know that Lin Chunhong's strength at the sea is of no other place, but it is just at sea and has nothing to do with the inland river. The sea boat has a deep draft, a huge body, is too bulky in the inland river, and has the danger of stranding. Except for being barely used on the river surface below Nanjing, it is almost impossible to use in other rivers."

Qian Qianyi pondered for a moment and said, "In other words, if you really want to form a navy, you only need to be stronger than Lin Chunhong's Yangtze River Navy?"

Shi Kefa shook his head and said, "Lin Chunhong's Yangtze River Navy has been raging in Jiangnan for five or six years. He has experienced a fierce battle with the Tartars. How easy is it to be stronger than him? This matter is not urgent, so he can only take it step by step. For example, the canal is narrow and not suitable for centipede boats to fight. We have to start from the canal, form a large number of small warships, and open up the waterway with the court, so that Lin Chunhong can stop the court from blocking the throat. After the canal is controlled by us, plan other rivers in the south of the Yangtze River... In short, we have to take it step by step. Besides, there is a navy loyal to the court, which is very necessary for the court and Donglin."

Qian Qianyi instantly understood what Shi Kefa meant, "a navy loyal to the court", the main meaning was not to confront Lin Chunhong, but to establish Donglin's private armed forces. It seems that under the stimulation of Lin Chunhong, the wealthy families in Jiangnan also had the idea of ​​limited independence. Learning from Lin Chunhong and establishing private armed forces was the first step.

However, can Zhu Youjian and Yang Sichang tolerate the establishment of the Navy?

Qu Shixi did not realize this, but was obsessed with the officials. He only thought about borrowing a navy to live in the temple. He became eager and said, "If what I expected was not bad, the emperor and Yang Ge Lao might be overwhelmed by the canal control of Lin Chunhong. This matter was closely coordinated with the court and worked together to achieve miraculous results."

After saying that, Qu Shixi looked at Qian Qianyi with anticipation, as if saying: Teacher, the opportunity to make a comeback is right in front of you!

Qian Qianyi and Shi Kefa are both good at humans, so why don’t you understand the meaning of Qu Shishi.

Shi Kefa's brow jumped, nodded heavily, and said, "Without the support of the court, this matter is indeed difficult to succeed."

Qian Qianyi was unable to make up his mind for a while. Although Qian Qianyi was obsessed with learning over the years and had close contacts with famous prostitutes Liu Rushi, and his life was quite comfortable, it was obviously impossible to say that he had lost his fame, fortune and wealth. However, now the government is controlled by Yang Sichang and has been trusted by Zhu Youjian. After entering the court, even though the Jiangnan family supported him, how much real power can he have?

What if Yang Sichang is narrow-minded and squeezes himself everywhere, will he be in prison again?

After thinking about it, Qian Qianyi said: "It is true that you have to obtain the approval of the court so that this matter can be done. But I am old and a little overwhelmed, and I am afraid I cannot be competent for coordination..."

Qian Qianyi turned his gaze to Qu Shisi, then looked at Shi Kefa, showing his expression of inquiry.

This action fell into Qu Shili's eyes, and his heartbeat suddenly accelerated, and even the sound of breathing could be clearly heard.

Shi Kefa was silent. It should be said that although Qian Qianyi was not as good as Qu Shisi, in terms of calmness and overall consideration, one hundred Qu Shisi could not catch up with Qian Qianyi. Now Qian Qianyi was unwilling to do so, so he had to give in.

Shi Kefa nodded and said, "This matter should not be delayed. Please ask Duke Tian to submit a memorial to the court, suggesting that the court form a navy to protect the canal."

Qu Shixi was about to shirk off the surface, but his servant suddenly informed him: Du Yinxi had something important to report to him.

The three of them hurriedly ordered Du Yinxi to come in, but were shocked by Du Yinxi's intelligence: the Xiongwei Legion of the Southeast Army set off camp from Yangzhou, took a boat to Shanghai, and then went upstream through the Huangpu River and set up camp in Tangdian, Huzhou.

The Pili Legion went westward against the Yangtze River and stationed in Shiji, Anqing, while the Shenji Legion stayed in Guazhou.

The three were shocked, and Qian Qianyi sighed even more and said, "We are still planning to establish a navy, so Lin Chunhong couldn't wait to put his hand into the center of Jiangnan. As Xiongwei Legion entered Huzhou, the essence of Jiangnan was under the threat of Lin Chunhong. I'm afraid that the gentry would not be able to fight against the water and fight to the death with Lin Chunhong. What can people do if they are like this?"

Shi Kefa thought for a moment and shook his head and said, "Mr. Muzhai's words are wrong. When dealing with evil dogs, there is a big difference between having a stick and not having a stick in his hand. I believe that all the gentry in Jiangnan understands this truth. Jingzhou holds a long spear in his hand. Even if Jiangnan only holds a wooden stick in his hand, it may break the backbone of Jingzhou. If he throws a rat, he will not dare to do anything randomly. Jiangnan has the capital for negotiation. If he doesn't even have a wooden stick in his hand, he can only let Jingzhou fish and meat!"

Qian Qianyi realized it and sighed in his heart: In terms of political struggle, he is indeed inferior to Shi Kefa, and even Qu Shisi. He should not go there to the muddy waters of the court, so as not to be left with no bones left.

Although he was discouraged, he also knew that if Lin Chunhong really mastered Jiangnan and Donglin's lineage, he would still not even have bone residue left. In other words, for the sake of the rest of his life, he had to try his best to prevent Lin Chunhong from completely taking Jiangnan in his hands.

After thinking for a long time, Qian Qianyi said: "The most powerful aspect of Lin Chunhong is the army. Our plan to build a navy is tantamount to the following four horses against the upper ones. Therefore, my opinion is that if the navy cannot be fully mastered by Donglin, it is better not to build it. If it is really built, it is best to attract but not to send it out. This is the best strategy."

Shi Kefa, Qu Shixi and Du Yinxi were amazed and nodded constantly.

Qian Qianyi was inspired and continued, "What is our Shangsi? It is the heart of the people and the pen! Last time we fought, we suffered losses from the new thing like newspapers, and I believe we won't eat it again this time."

"Also, Lin Chunhong is coming with great force. If he doesn't use all his strength this time, he may not have a chance next time. Therefore, we have to find ways to cut off Lin Chunhong's claws of plundering Jiangnan Minjin's fat."

"So, the army, people's hearts, money and food must be taken into three ways! Apart from these three aspects, we cannot be limited to Jiangnan. It would be better to find some trouble for Lin Chunhong in Jingzhou, which would be even better! Jingzhou is not a monolithic piece, you can do some moves!"
