The steam engine is still not good, even if the gearbox is added, it cannot be compared with the internal combustion engine in terms of volume, power, and speed. Li Yuanxing's flying boat is all in Shiyan, and it is already a miracle that he can cruise stably at a speed of 130 kilometers per hour.

The full speed of the machine is only about 160 kilometers per hour at the modern speed.

This speed is not comparable to that of the first generation of Zeppelins in history.

Seeing that he arrived in Luoyang, Li Yuan was excited: "Wulang, I am very happy!" ”

"Erchen wanted to let go of the speed, but this safety regulation for the speed limit was proposed by Mingyue, ordered by Tianying Pavilion, and ordered by the imperial brother. As long as Erchen is on this flying boat, the speed of the flying boat cannot exceed eighty. In wartime, it is not allowed to exceed ten percent, so the father can't experience the feeling of extreme speed. ”

"Enough, enough!" Li Yuan hahadaxiao.

The actual speed may be faster, Li Yuanxing looked at his watch, about ten hours in modern time, they were able to see the sea, and it took some time to land, and it was only less than eleven hours, that is, five and a half hours, and when the sky was not completely dark, they had already landed in Laizhou Port.

Li Daozong, who was dressed up to greet him, was also stunned when he looked at the huge flying boat. When he saw Li Yuan, he forgot to salute.

Li Yuan smiled and slapped Li Daozong's head: "Don't lose the prestige of the Tang Dynasty and let people from other countries see jokes." With that, Li Yuan looked at the foreign envoys with weak legs again, and strode towards the barracks with a smile.

Li Yuanxing didn't leave in a hurry, he was listening to various test reports.

Coal consumption, water consumption, machine operation. There is also the effect of crosswinds on the route, etc.

"Your Highness, we seem to be overloaded with coal and water. In total, less than 30% of the coal is used, and the water consumption is just 20%. Do you want to bring down some buckets and coal baskets, and then transfer some sergeants to the boat. Lu Maofeng took the document and reported beside him.

Li Yuanxing waved his hand: "There is no harm in preparing more, there are not many places where Datang can replenish coal now." In the future, if the generals used it to fight, let them calculate the loading of various materials themselves. ”

"Yes, Your Highness!" Lu Maofeng's heart was still thinking about fighting.

Li Yuanxing waved his hand and called Wu Bin: "A knife, you can't use a fake hand in a battle tomorrow." The Bae brothers attacked Pyongyang City with red blood, and you took the king's guards with you. Then let Bae Seungguang and you must enter the Goguryeo Palace. There is only one command from this king. Kill everything, burn everything, rob everything. Whether it's wealth, or women. The nobles of the Goguryeo royal family must be robbed alive and a few returned. Let Pisces take the hundred. to support you. In the event of a strong enemy. You can use all means, as long as you have fewer casualties! ”

A military order without the slightest limits.

A knife raised his head high, and then gave a heavy military salute: "The last general." Order! ”

Yaozhou, Wu Cao, who received the telegram, breathed a long sigh of relief, and while sending people to Chang'an City and Qin Wangfu, he put pressure on the craftsmen, because Wu Cao clearly knew that the steam-powered airship should be able to reach a speed of more than 250 kilometers per hour, or even 300 kilometers per hour, so the craftsmanship of the steam engine was not up to par.

His Royal Highness the King of Qin arrived in Laizhou, and the news was immediately transmitted to the armies by telegram. and Wei Chigong, who was heading towards the Datong River on the sea, also received the news and summoned the Pei family brothers, Pei Chengxian and Chengguang to the front: "You two lead the red blood, this battle Goguryeo insults me the Tang Dynasty and insults me the King of Qin, and your two brothers know the benefits!" ”

"The Lord humiliates his ministers to death!"

"One knife leads people to battle, all of them are the top masters of the Qin Palace. Pisces brought a hundred strong bows. When Wei Chigong said this, he took out a box and saw that the seal on the box was still there. Tearing the seal in front of the two of them, after reading the order, Wei Chi Xue smiled.

This command is naturally the same as that of a knife.

It is said that it is a madman, these generals who have experienced life and death many times on the battlefield, they like such orders without limits.

In a word, just kill, kill, kill!

Eat well, drink well, sleep well. Wei Chi Gong personally asked the captain that they would arrive at the mouth of the Taedong River before dawn, and they only needed to watch the signal from the sky to enter the river, go directly upstream, and enter the city of Pyongyang.

The next day, cook at 3 a.m. and leave at 4 a.m.

The envoys couldn't sleep all night, and they already knew very well that this was Datang in Liwei. Let them see what will happen to Goguryeo who dares to show their teeth at the Tang Dynasty, and ask, who can block this flying huge fortress, and what attack methods this terrifying hundred-zhang giant thing has, who knows!

It's not something that can be guessed by imagination.

Night flight is a huge test for all crew members who fly for the first time, even with the help of the positioning of the Big Dipper, there will be an error of hundreds of miles.

After an hour and a half of flight, Li Yuanxing has been standing expressionlessly at the front window.

Li Yuan was wearing a full suit of armor and was actually standing behind Li Yuanxing, in Li Yuan's heart, only wearing armor was a real war.

Li Yuanxing was wearing a very ordinary Han-style power suit, and he was not wearing armor.

Li Yuan could feel the nervousness in Li Yuanxing's heart, although he didn't know what Li Yuanxing was nervous about.

Maybe it's because if this battle can't be won, the pressure Datang is about to face.

So what is Li Yuanxing nervous about?

Two words, direction!

Li Yuanxing was really afraid that this flight would go in the wrong direction, and if it flew wrong, it would really throw people into the sky.

Suddenly, a shout came from the bottom of the command warehouse: "Report, I saw the signal of the sea ship, I saw the signal." ”

"Okay, send a signal and give the order to enter the Datong River. When the sun rises, as long as you are next to the city of Pyongyang, you will give those former Sui generals a credit, a great achievement! The expression on Li Yuanxing's face changed, he became more murderous, turned back to his chair, and patted the armrest of the chair hard:

"Pass on the king's order, the two ships of Weiyuan and Zhenyuan have entered a state of first-level combat readiness!"

What does the first level of combat readiness represent?

The envoys of various countries were different, but they saw that even the guards of the guest warehouse began to tie ropes around their waists.

Several guards came running up with ropes five feet long, first giving each guest a belt, and then tightening it to tie one end of the rope around his waist, and the other end to an iron hoop under the seat.

"Your Highness, please! Airborne or downhill? Wu Bin bowed down in front of Li Yuanxing and waited for the order.

Li Yuanxing closed his eyes and didn't answer immediately, he was still thinking.

Direct airborne landing is too dangerous, and if the opposing side has archer air defense, then a sergeant using a parachute will become a target. And he was completely sure of the downhill, the airship really descended to ten feet above the ground within the city wall, and it was absolutely safe for people to slide down from the rope.

Seeing that Li Yuanxing didn't react, he roared loudly: "Your Highness, please parachute in at the end of the general!" ”

Li Yuanxing did not answer immediately, but said: "Before the hour, if this king attacks with flames falling from the sky, half of the entire Pyongyang city will be surrounded by a sea of fire, and you will be in danger when you fall." Downhill is safer. And this king is still hesitating, setting fire to the city of Pyongyang, it will hurt too many people by mistake, I really can't bear it! ”

"Your Highness!" Wu Bin knelt on one knee in front of Li Yuanxing, and everyone behind him knelt down.

At this time, Li Yuan actually gave a heavy military salute in front of Li Yuanxing, which made Li Yuanxing jump up in shock: "Father, who are you?" ”

"Gorou, your name is Emperor My Father. Do you have a father in your heart, do you recognize this father? ”

"Admit it, how can you not admit it." Li Yuanxing was a little incoherent.

Li Yuan walked up to Wu Bin:

"They call you a knife, and I only ask you. When you were training in Yaozhou, did you know how strong this flying boat was? Do you know how to show my Datang might? ”

"The last general knows that Princess Mingyue specially gave the last general three days of class, and also gave the last general the opportunity to practice."

"Okay, I'll ask you again. Raise the prestige of our army and overseas, what are your plans! ”

Wu Bin hesitated a little and glanced at Li Yuanxing secretly. Li Yuan was furious: "I'm asking you, I'm still the emperor." Gorou is my son, and I'm asking you. Answer me! ”

Wu Bin gritted his teeth:

"The minister burned the entire Pyongyang in an hour, and the minister led troops to raid the Goguryeo royal palace, even if the Goguryeo people were a hundred times the strength of the ministers, they could at most ensure that their king escaped, and the whole Pyongyang was also under the control of my Tang Dynasty, and with the cooperation of General Wei Chi and the troops, Pyongyang City could cut off all the Goguryeo soldiers, slaughter all the Pyongyang cities, capture the Goguryeo royal family, empty all the warehouses of the Goguryeo royal family, and burn all the grain in Pyongyang City!"

When Li Yuanxing heard this, he closed his eyes.

What Wu Bin said is almost the most brutal way to fight this battle, and it is also the most effective way.

Obviously, this trick was not something that Wu Cao could come up with.

It is very likely that it was designed by the cabinet master, and then directly transmitted to Wu Cao through Li Lanshan, no wonder Wu Cao will specially train Wu Bin.

Li Yuan turned around: "Goro? ”

"What Wu Bin said is not wrong, but it is still a little worse. It should be said that whoever I want Datang to live, who can live. ”

"I'm going to give an order?" Li Yuan continued to force Li Yuanxing.

Li Yuanxing smiled and shook his head gently: "Father, it seems that I am still too soft-hearted." I understand, this is the Tang Dynasty, this is the first war with the outside world, this is the battle of Liwei. Wu Bin listens to orders! ”

"The last general ......

Half an hour later, the city of Pyongyang ushered in the early morning of the second day of the fourth lunar month.

And what they saw was not the rising sun, but two huge monsters hovering over the city of Pyongyang for hundreds of feet. People who know words can see the words Weiyuan and Zhenyuan.

Li Yuanxing held the jade fan in his hand and waved it lightly: "The Weiyuan arc flying line and attack Pyongyang City." ”

The Weiyuan moved, and the envoys of the various states sitting on it all leaned to the window without exception, they already knew that this was Pyongyang, but they did not know what would happen.

Li Yuanxing continued to order: "Zhenwon, attack the military camps in Pyongyang!" (To be continued......)

PS: It's on.
