Chimneys of various factories sprung up like mushrooms after a rain on the Pearl River Delta. The small rivers flowing through Foshan were pulled up to dams. The height of those dams was not high, most of which were only three to four feet high, forming a small drop, but such a small drop was enough to drive the water truck to rotate. Walking along the way, you can see that there were endless turning water trucks under the short dams. In the past few months, Foshan not only integrated steel workshops of various sizes and large, established multiple steel factories, but also established many cement factories, glazed factories and other factories. Factory chimneys are lined up, which is the credit of cement. With the new building materials of cement, the building can be completed quickly.

The chimneys spit out clouds of black smoke, seriously polluting the environment. The wastewater discharged from factories has turned the rivers black. Environmental pollution is just beginning. As humans enter the industrial age ahead of schedule, more serious pollution is still ahead: air pollution, water pollution, and especially air pollution, will cause serious greenhouse effects in the future.

Li Guodong didn’t know if he could see blue sky and white clouds in two hundred years, how much temperature on the earth would rise, and whether the development of human civilization would perish due to serious damage to the environment, but those are things that will happen in the future. We will develop first, and then future generations will click on the technology tree of controlled nuclear fusion.

Sir Newton has come to this world and the law of gravity will be born soon.

In the future, before Li Guodong was about to leave this world, he would leave a law of mass energy transformation for future generations and tell future generations that the energy of the sun comes from nuclear fusion, leading the technological tree of future generations to controllable nuclear fusion.

Only the birth of controlled nuclear fusion can human civilization continue. Otherwise, as human energy consumption increases, the greenhouse effect will become more and more serious. The temperature on the earth rises and forest fires are severe, which further increases the greenhouse effect; the permafrost layer melts, and methane gas frozen in the permafrost layer enters the atmosphere, which is a greenhouse gas that is more serious than carbon dioxide, which will make the greenhouse effect more serious. As the temperature rises, the water vapor in the atmosphere increases, the atmosphere thickens, and the temperature becomes higher and higher. Once it reaches the point of entering the irreversible greenhouse effect, the earth will become the second Venus.

There are more than 5 billion years for the sun to become a red giant. As the sun's hydrogen continues to consume and helium continues to increase, the sun will become hotter after more than one billion years, making the earth unsuitable. However, more than one billion years are very long. If human civilization is immortal, it can enter level 2 or above civilization within more than one billion years. As long as it enters level 2 civilization, it will reach a stellar civilization, which can draw away the sun's helium and extend the life of the sun.

But the question is, can the environmental damage caused by human beings give more than one billion years? There are also threats from asteroids, threats from nuclear war, etc. If this continues at the rate of greenhouse effect, it is a question whether human beings can survive for a thousand years.

Therefore, the ultimate path is to follow the path of controlled nuclear fusion to extend human civilization.

But those are things in the distant future. What Li Guodong has to do at present is to let the Ming Dynasty enter the industrial era. Whether it is the barbarians, various foreign races, and the Western world, it has formed a technological crush on the barbarians, the various foreign races, and the Western world. Only by making China invincible, allowing China to assimilate other countries and nations, and complete global unification as soon as possible can we eliminate the threat of nuclear war and concentrate our efforts on developing higher technology.

Under the leadership of Song Yingxing, Li Guodong came to the largest factory.

The outer wall of the factory is surrounded by high walls. At the door are four soldiers wearing plate armor, holding shields and steel knives, and two short guns on their waists stand guard. Standing at the entrance of the factory, you can see that this is an arsenal. The factory is extremely large in scale, with multiple factories and a river flowing through the factory area. It is obvious that river dams have been built in the factory area to drive mechanical equipment with water trucks, greatly improving production efficiency.

Li Guodong had sharp eyes and could see at a glance that the short gun on the guard's waist was completely different from the short gun he had seen before. So he asked Song Yingxing to stop and then said to the soldiers: "Brother, can you show me the short gun on the waist?"

The soldier saluted, took off the short gun from his waist, and put it on with both hands.

Li Guodong took the short gun and found that this short gun was different from the fire guns he had seen in the past. This short gun was actually a flintlock-style tiger-winged gun!

The so-called tiger-winged gun is an improved three-eyed gun, which means changing the three-eyed gun that originally belonged to the fire gate gun into a colloid gun. The tiger-winged gun has three gun barrels, tied with the finished shape, and there is a rotation shaft in the middle of the three gun barrels, which is connected to the gun barrel. Each gun barrel has its own medicine pool. Pull the trigger, press the bullet into the medicine pool, ignite the medicine, and then ignite the launching medicine. Fire a gun, turn the gun barrel with your hand, aim the next gun barrel at the position of the gun barrel, and then pull the trigger and fire again.

The tiger-wing gun is a three-barrel convex gun. Because each gun is built separately, it is much more powerful than the three-barrel and has a range far more than the three-barrel. It is triggered by a trigger, so it can be aimed and fired calmly. The accuracy and convenience of use are far greater than that of the three-barrel.

However, the tiger-winged gun in front of me was a tiger-winged gun with a shorter barrel, and the firing method was replaced by a flintlock machine.

Li Guodong held the gun in one hand, aimed at the target twenty steps away, pulled the trigger, and the spring steel strip drove the flint to hit the iron sheet of the bolt, spewing out the sparks, igniting the drug. Only a deafening sound of the gun was heard, and the projectile accurately hit the center of the target twenty steps away!

"The king of the country is good at gun technique!" Everyone around praised it.

Only then did Li Guodong realize that while pulling the trigger to press down the spring steel plate, after releasing the trigger, the barrel of the short gun turned the position of the tube automatically! This means that as long as the trigger is pulled again, the tiger-winged gun can be fired again!

"The design is clever! The rotating the gun barrel and the pressing flintlock machine achieve a linkage! Such a sophisticated design, is it Mr. Song's credit?" Li Guodong asked.

Song Yingxing shook his head modestly: "It's not the credit of the student, it's the credit of Mr. Dai and a Thai man."

"Mr. Dai? Who is the master?" Li Guodong asked.

Song Yingxing said: "Mr. Dai Cang."

When Li Guodong heard the words Dai Cang, he knew that Dai Cang was the father of Dai Zi, the famous firearm master later! Dai Zi was just born at this time and was still a baby under the age of one year, but Dai Cang was already a famous firearm master.

Such a sophisticated linkage mechanism cannot be completed by Dai Cang alone, so it can be completed by the cooperation of a Western watchmaker.

"Call Mr. Dai quickly, my country's Duke wants to see him." Li Guodong said.

After a while, Dai Cang was called to Li Guodong: "Students have met the Duke."

"This tiger-winged gun is your masterpiece? If we can build one more batch and give each cavalry soldier of our army, then our cavalry will be invincible in the world!" Li Guodong said to Dai Cang with approval.

Who knew Dai Cang replied: "Dude, this thing is as rare as the magic gun (rifted gun) you want. Each one is expensive to build and cannot be made in large quantities. Instead, the tiger-winged gun with the hand-turned gun barrel can be made in large quantities."

Although Li Guodong was a little disappointed, he was still very happy: "It's okay, you can build a small number of self-rotating tiger-wing guns to equip the cavalry without quitting the sentry; the hand-rotted tiger-wing guns can be made in large quantities, and the Duke of the country must equip each cavalry with two. In this way, each cavalry can shoot six bullets and then charge."
