After the white dew in early October, the weather has gradually become colder, and Zhu Changhao is in the palace, looking at his pair of children, and his heart is overjoyed.

Since Liu Zilian gave birth, she has become more virtuous, and she has to "hand-to-hand" with Zhu Changhao on the kang eleven or twice a month, and she is becoming more and more indulgent, and many difficult postures can be made.

I don't know where she got a few volumes of the three-color overprint "Spring" from the Zhengde period. Palace. Sometimes, Liu Zilian will ask the prince to follow her according to the spring. Palace. Figure on the pose to do.

Inside the dormitory, spring is often proud, and the room is full of spring.

It's just that sometimes, Liu Zilian also knows that as the eldest lady and concubine of the palace, she can't dominate the princess's rain and dew, and she still has to let the prince and other female relatives play the dragon and phoenix appropriately, including her own maid Qiao'er, as well as Dong Wanning from Liaodong.

Zhu Changhao likes to do it with Dong Wanning the most, after all, Dong Wanning is very charming, plus she is literate, and the most important thing is that this woman has ten names. One of the jade mussels contains beads.

Every time Zhu Changhao can feel the suction of the jade clam containing pearls, and he is not tired of it, if he doesn't practice the "Yellow Emperor's Neijing", when Wanning girl sucks shun, he immediately runs the exercises to promote the integration of yin and yang between each other, that feeling, it is simply walking in the clouds, and the soul has a trembling feeling.

Through this matter, Zhu Changhao also understood a mystery from ancient times to the present, "Why don't many kings love the country and love the beauty?" ”

Because these kings are animals with lower body thinking, and these beauties are all famous. The man of the instrument, the king is intoxicated with it, and cannot extricate himself.

In mid-October, Dong Wanning's father came, named Dong Chongming.

Dong Chongming came, except for meeting Zhu Changhao on the first day, in the next few days, Zhu Changhao asked Xu Guangqi to be his matchmaker and discuss with Dong Chongming the marriage of Miss Wanning.

Of course, Dong Chongming, as a member of the Guandong region, couldn't imagine that his daughter was really going to marry the hottest prince in the Ming Dynasty, and he was quite happy.

This marriage matter was naturally agreed.

Just three days after Dong Chongming came, Zhu Changhao began to marry Miss Wanning as one of the concubines of Rui Wangfu.

There are a total of four concubines, one concubine, and a number of side concubines, but Zhu Changhao feels that if he wants to marry the princess, he must have his own feelings after all, and it is impossible to let him vent. The tool of desire, besides, women are used to love and care, if you want to find catharsis. There are too many tools to desire, go directly to the vegetable market, cut two catties of pork, and make a cut in the middle, which is enough.

Three days later, when Zhu Changhao, who was dressed as a groom, and Dong Wanning, who was wearing a red hijab, completed the first ceremony of their lives in the cave room in the dormitory.

The next day, Dong Chongming left, and Zhu Changhao directly wrote a warrant and handed it to Song Xiance when he returned to Liaodong.

This warrant is Zhu Changhao's request for the Beiyang Navy Division to assist his old mother-in-law in moving from Gaizhou.

After preventing it, when King Rui wanted to set foot on Liaodong and pacify the Jurchens, this Huang Taiji suddenly stinked and shameless, and took Dong Chongming as a hostage, which was a huge blow to himself and Miss Wanning.

Taking precautions has always been Zhu Changhao's routine, but now he has to use public weapons for private use once, and let the Beiyang sailors move his father-in-law, and he can only make this decision.

Dong Wanning is not a girl in the room after all, so Zhu Changhao is marrying in the media, and at this time she was a little wronged Qiao'er, as Liu Zilian's escort girl, she married into her husband's family, which is the life of the girl in the room, but Zhu Changhao felt that he should find a suitable time and let Qiao'er be his concubine.

The atmosphere in the palace is so friendly and harmonious, but outside Jizhou Town, this time it is really going to face the invasion of the Manchurian and Mongolian coalition forces.

The news came from Jizhou, and the Houjin soldiers divided into three routes, all the way to Da'ankou, and the general Zhou Zhen died; All the way to Longjing Pass, all the way to attack Hongshan Pass, the Ming staff general Zhang Ande and others were defeated and fled, and Zhang Wanchun surrendered. Jizhou was besieged, and in November, Beijing was under martial law.

Unexpectedly, history repeats itself, although the cavalry led by Fu Zonglong, although in the process of going north, changed from a foot soldier on horseback to a cavalry, but compared with the cavalry of the Eight Banners, there is indeed a considerable gap.

It's just that Huang Taiji didn't take much advantage, because the cavalry of the palace played a black hand in the back and put cold guns, and the losses of the Manchurian and Mongolian coalition forces were still quite large.

Almost 6,000 people died under the sword of the royal cavalry.

In addition, at the three passes, because Zhu Changhao sent a large amount of grain, meat, and 10,000 catties of black fire in time. Medicine, Huang Taiji and them, including the coalition soldiers of Horqin, all blew up on their backs.

Zhu Changhao discussed with the members of the military cabinet, and immediately sent a letter to Fu Zonglong about the transfer of troops from the military department, asking them to go south to King Qin.

For those coalition forces who dare to invade the Guannai, don't be soft-hearted, don't be afraid of despicability and shamelessness, and kill as many as you can.

Just when this letter of transfer was sent, Zhu Changhao asked the soldiers of the logistics baggage battalion to bring 10,000 burning. bomb, ready to let the Jiannu and Cole coalition troops taste the taste of "braised pork".

Around the Jingshi of Jizhou, now there is a smoke of gunpowder, and the sound of shouting and killing is gradually rising, Zhu Changhao can't lead the troops in person, but he still has to stay in Hanzhong and watch the construction of a steam ironclad ship.

After all, in the more than a month since Zhu Changhao came back, the Ordnance Supervision Department carried out the production of steam ironclad ships in accordance with the shipbuilding standard of 300 tonnage.

At the end of October, due to the installation of paddle wheels on both sides of the middle hull, the guide hull swirled in the river water, swayed, and could not operate.

Later, according to the experience of the old boatman, after installing the paddle wheels on both sides behind the hull, the ironclad boat actually moved slowly on the water.

It's just that the speed is about the same as a human walk.

Originally, according to the initial technological progress, this steam boiler should be simple, but Zhu Changhao felt that Daming must develop by leaps and bounds, and besides, as a traveler, let Daming's industrial steam engine technology advance by leaps and bounds, which must also be in line with God's will.

In the palace, recalling that he saw the steam boiler in the 21st Century Museum, Zhu Changhao said directly to the masters of the palace, "The fuel and the parts that produce steam mainly include three parts: the fire box, the pot carcass and the smoke box.

The firebox is composed of two parts: the inner firebox and the outer firebox, the bottom of the inner firebox is the hearth, and the lower part of the hearth has an ash box for storing the ashes. There are different numbers of large and small pipes arranged in the carcass of the pot, and the large pipes are sleeved with superheated pipes to dry and heat the steam. Boiler water is stored between the inner and outer firebox and in the pot carcass, and the pot water covers the top plate of the inner firebox and the large and small smoke pipes, forming a steam space on the evaporation surface of the pot water. The smoke box is located in the front of the pot carcass and contains ventilation devices such as a chimney, exhaust air vent, reflector and Mars net.

The coal is put into the hearth, and the heat energy is mixed with the air entering from the ash box damper in the firebox to produce heat energy, which is transmitted to the surrounding pot water and the steam in the superheated pipe through the inner firebox plate and the large and small smoke pipes, and the smoke enters the smoke box and is discharged through the guò chimney. The high-pressure and high-temperature steam enters the steam turbine from the steam drum at the highest point of the boiler through the steam path such as the adjusting valve, the drying pipe, the superheating pipe and the main steam pipe. ”

Using the pattern of drawing with a ruler and gauge, this drawing was pointed out to Dai Cang and others of the Ordnance Supervisor, and Zhu Changhao was suddenly called a god by the craftsmen of the Ordnance Supervisor.

The boiler of the steam engine appeared, but the steam turbine and the drive shaft also had to be modified.

In view of sending the Buddha to the west, Zhu Changhao, the steam turbine, did not talk nonsense, and said directly, "Everyone, please see, the parts that convert the thermal energy of steam into mechanical energy. The steam engine and the mechanical part include the steam chamber, cylinder, piston (also known as the steam bar), crosshead, rocker, connecting rod, valve actuator and other components.

The valve actuator is a steam distribution mechanism that controls the coordinated action of the steam valve and the piston, and is used to regulate the amount of steam entering the cylinder and realize the forward or backward movement of the locomotive. After the high-pressure, high-temperature and superheated steam generated by the boiler enters the steam chamber, it enters the cylinder through the steam distribution effect of the valve actuator, expands in the cylinder and works work, and when the piston is pushed, the mechanical energy is transmitted to the driving wheel through the piston rod, crosshead, rocker and other mechanical parts, and then transmitted to other paddle wheels through the connecting rod. ”

Zhu Changhao's construction is very good, and just when he was about to plan and finalize, Zhu Changhao suddenly told Yu Kaiyi of Fubo Water Master about this idea.

This guy looked at the ironclad ship and said to Zhu Changhao, "Lord Wang, aren't our wheels ready-made?" ”

When Zhu Changhao heard this, he immediately thought of a report he had seen in his previous life, "The paddle steamer is a ship propelled by paddle wheel thrusters, and it is an early kind of mechanically powered ship. It evolved from the ancient Chinese wheel ship.

The steam engine is used to power the ship, and the propulsion tool used in conjunction with the steam engine is the paddle wheel. It is equipped with blades on the outer circumference of the runner to become a rotating paddle wheel, which is mounted on both sides of the ship or in the stern.

According to the arrangement position, paddle wheels are divided into broadside paddle wheels and stern paddle wheels. ’

Zhu Changhao heard it and thought it was very good, but he still said, "General Yu's idea is very good, but the structure of this paddle wheel is bulky and inefficient, especially in the event of wind and waves, the blades of the paddle wheel are partially or completely exposed to the water, so that the ship cannot sail steadily." Moreover, the blades of the paddle wheel are easily damaged when used.

Half of the leaves rotate in the air when the paddle wheel rotates, which not only increases the width of the ship and the resistance when sailing, but also when it is docked at the dock, it is easy to collide with the ships on both sides, which not only affects its own safe driving, but also has the possibility of abrasion other ships. In addition, if a winding object such as aquatic weeds gets caught in the blades or shafts of the paddle wheel, there is a possibility that the paddle wheel will lose its rotation. ”

"Then the prince, what should we do?"

"This king came down and drew a picture and turned the paddle wheel into a propeller, and it should be fine. Moreover, the propellers are all stamped using steel. ”

Finally, the first ironclad ship of Ruiwangfu used two boilers and propellers for power propulsion, and sailed fifty miles per hour, which is about thirteen nautical miles if calculated according to nautical miles.

On November 11, it is said that this is the Singles' Day of the 21st century, Zhu Changhao perfectly completed the cruise of the first Ming Dynasty and the world's first steam ironclad ship on the Han River outside Hanzhong City.
