Cheng Yue personally inspected the results of the aiming, was very satisfied, stepped back and ordered: "Everyone cover their ears and fire!" ”

Everyone hurriedly covered their ears tightly, only to hear the sound of "boom", the muzzle of the cannon spewed out blazing flames, and an extremely difficult to find black shadow instantly hit the boulder, and there was a violent explosion, the stone flew sideways, the smoke of gunpowder rose everywhere, and the boulder was blown out of a shallow pit!

Cheng Yue nodded approvingly, and gave two orders to open fire. Pen @ fun @ pavilion wWw. ｂｉｑUｇE。 The info artillery still hit the target accurately.

Jinjin stared blankly at Dashi, and couldn't believe his eyes! It was the first time he had seen Cheng Yue's artillery, and he had never thought that the artillery could be so accurate and powerful! In the face of artillery, what is the use of the city walls that Dayuan spent a lot of money on building in various places? You know, it's just a humble cannon! No wonder Instigating Du and others unanimously decided that Cheng Yue was invincible in the world based on siege alone!

The only thing the Mongols could counterbalance Cheng Yue was the speed and impact of the cavalry!

Tuhuan, Buhumu and the others were also so shocked that they couldn't move, if there were hundreds of these small cannons bombarded at once, even if it was a natural danger like Diaoyu City, it could be easily broken! Compared with the previous solid bullet, how many times more powerful?

Except for Nangkajin and Kutoulon, many women have never been on the battlefield, nor have they experienced the horror of artillery attacks, and they are even more frightened! It turns out that the war is so cruel, just a small cannon, a few shells, how many people will die?

Kudu Lujian was so excited that he clenched his fists and almost shouted!

What a mighty army this is! It turns out that Cheng Yue still has so many hidden secrets!

Cheng Yue said: "This is just a small flowering bomb, and the big one has also been manufactured, and it is being tested in Suzhou. In addition, there is also a howitzer that can shoot at a curve, and if combined with accurate shooting, the efficiency of shelling can be increased several times, although it is far from satisfying me, but with today's capabilities, it has reached the limit. Further down, it is necessary to rely on steam power to seek the improvement of precision and efficiency. ”

After Cheng Yue finished speaking, everyone listened as if they had fallen into a fog, and at most they only understood half of it. But one thing they know very well is that Cheng Yue has made an earth-shattering invention again!

Cui Yu stammered and asked, "Lord Wang, dare to ask...... What is the steam power that the prince is talking about? What's ...... Unique? ”

Cheng Yue smiled, pointed to the mast in the distance, and said, "I was about to take you to see it, this place has just been installed, let's go." ”

There are stairs on the side of the valley to climb up, and Cheng Yue led everyone over the hill to the back of the island. When I reached the top of the mountain, I suddenly saw that there was a strange-looking ship parked on the side of a simple but sturdy pier!

Compared with Cheng Yue's boat, this boat is not very large, only about 20 zhang long, but the workmanship is extremely exquisite, most of the places are wrapped with steel plates, which seems to be bulky, and the most conspicuous thing is that there are two thick chimneys in the middle, but there is no hole for paddling!

Zhenjin looked at the ship in amazement, he was not an expert and could see that this boat would be extremely slow to row by manpower, or that it would not be able to row at all!

What's going on?

There were some people dressed in black on the boat who were busy, and when they saw Cheng Yue in person, they hurriedly stopped what they were doing and saluted Cheng Yue.

Cheng Yue waved to them, and soon led everyone onto the deck. Cheng Yue left them to wait on the deck, and he and a few craftsmen went into the cabin to check the condition of the ship.

Cheng Yue, who greeted everyone for the time being, was a young craftsman, only in his twenties, called Zheng Guang, who had just been transferred from Suzhou, and seemed to be extremely shrewd and capable.

Bu Mu was anxious to figure out the ship, so he grabbed Zheng Guang and said, "Tell me quickly, what's going on with this ship?" ”

Zheng Guang smiled: "Don't be anxious, let me explain slowly." ”

Bu Mu said: "Okay, then you can say it quickly." ”

Zheng Guang pointed to the chimney and said, "You nobles must have seen that this ship does not rely on manpower, but on burning coal or firewood, and this chimney is for exhausting. ”

Everyone was shocked!

What the? A ship that does not rely on manpower!

Can you use coal and firewood to make a boat move?! How is this possible?!

Cha Ba'er shook his head and said, "Impossible, don't lie to us, how can burning firewood make the ship move forward?" It's a joke! ”

Zheng Guang knew that someone would say this, pointed to the stern of the boat, and said, "Ladies and gentlemen, please come down with me." ”

Everyone followed Zheng Guang to the stern of the boat, Zheng Guang pointed to the water, and said, "Ladies and gentlemen, please look, do you see a crooked thing under the water?" ”

Everyone looked down, and sure enough, they saw several very strangely shaped pieces of iron cast together, lying quietly in the water.

Dong Shixuan said in surprise: "What is this?" Why is it so weird? ”

Zheng Guangdao: "This is the invention of the prince, named the propeller, it is very complicated to make, and the best hundreds of craftsmen in the Great Song Dynasty have been working for two years under the continuous guidance of the prince before they have roughly mastered the method." Even today, if ten are made, eight must be invalidated. After the propeller was made, the prince was extremely happy, and the four craftsmen who made the first contribution each gave the first house! ”

Everyone was shocked again, and He Li Huosun was stunned and said: "The prince actually gave such a heavy reward to the craftsman, just for these few iron pieces?" ”

Zheng Guang laughed and said: "If the adults think it is simple, you might as well try to do it, if the adults can also make it, maybe the prince will also give the adults a mansion!" ”

Li Qian didn't want Zheng Guang to be interrupted, so he immediately asked, "So, what is the purpose of this propeller?" ”

Zheng Guangdao: "It's a long story, in short, the water is heated first, and after the water is hot, there will be steam, and the steam will push the piston back and forth, and the propeller will be brought up and pushed the boat forward!" ”

Most people still don't understand it, but a few people who have studied the process and the work have already understood it, but they still don't know the specific method.

Li Meng then asked again, and at this time, he saw Cheng Yue coming out of the cabin, with some black ash on his face and body.

Wan Ze and other wives and concubines hurriedly took out their handkerchiefs and wiped them for Cheng Yue.

Cheng Yue didn't care, but his face was full of excitement, and said: "It's already usable, and the efforts of more than two years have finally not been in vain!" ”

Cheng Yue said to Zheng Guang: "Go to the ignition test ship, I want to see how the speed is?" ”

Zheng Guang saluted and went to operate the boat. Cheng Yue looked up at the thick chimney and was pleased.

Zhenjin asked, "Lord Wang, can this boat really be rowed without people?" ”
