Although Chen Xu had already used artillery in the East China Sea four years ago, what he had seen was Chen Xu and a group of musket team teenagers, as well as a group of craftsmen from the Academy of Sciences such as Hu Kuan and Zhang Cang, and after killing Huang Shigong and rescuing the water gentle, this matter was strictly ordered by Chen Xu not to be said, so this matter has always been kept secret.

But today, the artillery that has been hidden by Chen Xu for a long time is finally truly presented in front of the Great Qin people, and even Hu Kuangong and Zhang Cang and others clearly know that the three cannons in front of them are essentially different from those cannons four years ago.

These three cannons have undergone earth-shaking changes from steel to style to processing technology, and they are far from being as simple as a stupid and stupid iron pipe.

"Your Majesty, now that the targets have been set, you can demonstrate the power of the cannon for your Majesty at any time, and then give the name of the cannon after Your Majesty finishes watching, then this magic weapon can start to be cast and used on the battlefield!" Chen Xu stood next to him and reminded softly with a slightly serious expression.

"Oh, okay, okay, then please ask Aiqing to arrange a test gun, I will take a closer look!" Qin Shi Huang hurriedly withdrew his hand from the gun carriage and nodded.

"Your Majesty, this cannon is so powerful that it may be in danger of exploding, so please also ask Your Majesty and your colleagues to step back and watch, so as not to make mistakes!" Chen Xu reminded again.

"Okay, all of you Aiqing are subject to the young master's arrangement, and you will step back and watch with me!" Qin Shi Huang's big sleeves were placed under the protection of a group of Xuanwu guards, and he stood twenty feet back, and a group of civil and military ministers also hurriedly followed the fart and left, and a large area around the cannon was instantly vacated.

"Your Excellency use this thread to plug your ears first......"

Several teenagers carried baskets and began to distribute woolen balls and binoculars to the emperor and everyone on the scene, many people looked at each other with woolen balls and didn't know why, and Hu Kuan, Zhang Canggong, and others all hurriedly stuffed the woolen balls into their ears.

"How do you do things that cover your ears and steal bells, don't you see with your eyes?" Chen Ping, Fu An and other people from the newspaper were holding woolen balls, and they were very puzzled when they watched the movements of Hu Kuan and others.

"When this cannon is fired, there is thunder, you had better plug your ears first, and you should also open your mouth a little ......" Zhang Cang kindly reminded.

"Hey, Thunder, why make such a fuss, don't use this thing!" A military general in a brocade robe next to him threw two balls of wool on the ground with disdain.

"Yes, what a fear of thunder, I have heard it since I was a child, I have never been scared, and I don't need it!" Another officer also threw the ball of yarn at his feet.

"Hehe......" Hu Kuangong and the others showed weird smiles one by one, shook their heads and stopped talking.

Of course, some people don't think so, and some people are smart, many officials still follow the young man's reminder to plug their ears, after all, many people have already heard of the prestige of Taiyi Divine Thunder, and it has already been rumored when the Eastern Road was built.

At the time of distributing the woolen regiments, Chen Xu had already gathered more than a dozen teenagers from the musket team who were in charge of firing the cannons and carefully admonished them, and once again used binoculars to watch the situation around, so that the lieutenant forbidden army also spread out to the sides and rear for dozens of feet, and then retreated to the side of the first emperor, and also took out two woolen regiments from his pocket and said with a smile: "Your Majesty, remember to plug your ears, otherwise you will be frightened when you fire the cannons!" ”

The First Emperor was very obedient and plugged his ears, and at the same time ordered a group of Xuanwu guards around him to also plug his ears.

"Your Majesty and Lord Hou, don't worry, blocking your hearing will make people slow to react, and those of us who practice martial arts are not afraid of thunder!" The Xuanwu Wei Commander directly rejected the kindness of the First Emperor.

"It's okay, be careful not to disturb others!" The First Emperor nodded and looked intently at the three cannons.

This group of musket team teenagers led by Chen Yong had trained artillery in the East China Sea at the beginning, although the cannon was much more well-made, but the firing method was still exactly the same, so four people were responsible for a cannon, one was responsible for observing the target, one was responsible for adjusting the barrel and firing, one was responsible for loading ammunition and cleaning the chamber, and one person was responsible for firing orders with a command flag.

Four-person cooperation is the standard configuration of artillery firing, Chen Yong as the commander of the unified command, pry open the wooden box, load ammunition, adjust the barrel, after a seemingly chaotic but orderly busy, the three guns were loaded.

"Report, the first gun position is ready, and the cannon can be fired!"

"Report, the second gun position is ready, and the cannon can be fired!"

"Report, the third gun position is ready, and the cannon can be fired!"

The three teenagers holding the order flag turned around one after another to report.

"Report to Master Hou, the cannon has been loaded, request to test the cannon!" Chen Yong strode up to Chen Xu and saluted.

"Let's start testing the gun!" Chen Xu nodded with a serious face.

"Prepare to test the gun~" Chen Yong roared and raised the red order flag in his hand, and at the same time blew the siren hanging on his chest.

Amid the shrill siren, soon a siren sounded near the abandoned palace two miles away, and a red flag could be seen raised high and swaying in the wind.

"Ignition and open the cannon~" Seeing the order flag in Chen Yong's hand falling, the young man holding the order flag at the No. 1 gun position raised the order flag in his hand and shouted.

"Poof~" The young man in charge of the launch struck a match and lit the fuse, accompanied by a slight sound and sparks of puff, a faint green smoke curled up in the air in the strong sunlight.

Thousands of forbidden troops, hundreds of princes and princesses, and everyone including the emperor all stared at the smoke with their eyes, and their hearts were extremely nervous, and the scene was as quiet as death, and only the sound of the wind and some people adding their mouths because of nervousness could be heard.

In the midst of the puff and sparks, the lead shortened rapidly at a speed visible to the naked eye, and after about ten seconds, the lead finally burned out, and only a thicker green smoke could be seen coming out of the lead hole.

"Boom~~"

Just when everyone was so nervous that they couldn't breathe, suddenly the artillery shook suddenly, accompanied by a deafening explosion, a strong fire spewed out from the barrel in the sun, only to see an almost invisible black light and shadow with a piercing scream breaking through the air, and thousands of onlookers almost at the same time staggered, screaming in terror and neighing of war horses, not only the civil and military officials who did not plug their ears sat on the ground and covered their ears and howled, but also the frightened forbidden army fell from the horseback, There were also frightened war horses neighing and fleeing, and the entire test site was instantly overturned by people, and the telescope and the Changge Jingqi Ding fell to the ground, and even a group of Xuanwu guards who were said to be strong in martial arts, many of them also trembled with horror and retreated, and the task of protecting the emperor was thrown out of the clouds in an instant.

In addition to the frightened souls of these people who didn't plug their ears and pretended to be forced, even those who plugged their ears were still shocked, and almost all of them couldn't help but tremble.

At the moment when the cannon body sounded, the First Emperor's body trembled obviously, but he quickly regained his calm, Meng Tian and Feng Qujian and the others were similar, but only Chen Xu and Hu Kuan and others had calm faces, and naturally they barely reacted at all, but they all smiled and pulled out the woolen ball from their ears and began to talk and laugh.

"Bang~~"

When the onlookers were staggered, a corner of the abandoned palace two miles away burst into a cloud of bricks and stones, and at the same time as a puff of smoke and dust rose, the already decaying palace collapsed in a large area.

"Drop~~" Accompanied by the shrill siren and the shaking white order flag, several teenagers who were in charge of watching the target ran over to observe, and after a while, they played a simple flag language.

Chen Xu, the First Emperor, Feng Quji, Meng Yi, Zhao Hai and a group of princes and princes all held binoculars to observe.

"Sure enough, the power is powerful, and a corner of the eaves has completely collapsed, which is really like thunder!" Qin Shi Huang calmed down and held up the telescope and kept nodding.

"Sure enough, it doesn't lose the name of God and Thunder, if it's a big ship, I'm afraid this cannon will be shattered!" Feng Qujian sighed and observed carefully.

"It seems that this cannon is still sharp when used for siege!" Meng Yi nodded.

"Hehe, you think too simply, although the Taiyi God Cannon is powerful, but this palace has also been abandoned for tens of hundreds of years, and it has long been decayed, so it has the power it looks like now, but if it is a blue brick and stone wall like Xianyang City, I am afraid that it will fly at most two or three feet and a gap, and it will not be able to hurt the root at all!" Chen Xu explained with a smile.

"Although the Marquis of Qinghe said so, the power of this divine thunder cannon is still terrifying, and no carriage or boat can stop ......"

Many officials calmed down and began to observe and express their ideas, and the officials and forbidden soldiers who had just been shocked also slowly settled down, but they all opened their mouths wide and kept plucking their ears, only feeling that their heads were buzzing and they could hardly hear any sound.

"Report, the No. 1 gun test firing has been completed, and it deviates from the target due north and left three degrees, and deviates from the distance of twenty feet, requesting a second test gun!" Chen Yong ran to Chen Xu again with a serious face to report.

"Accurate!" Chen Xu put away the binoculars and nodded.

Soon, with Chen Yong's password and the siren of the command flag, the second recalibrated cannon ignited the fuse.

This time, all the onlookers learned to be obedient, there were woolen groups to block woolen balls, and those without woolen groups used their hands, and many forbidden soldiers also covered their horses' ears with their hands.

Soon, as the fuse burned out, the second cannon spewed out a puff of smoke in the midst of the vibration, and with a roar, a puff of smoke rose again from the abandoned palace two miles away, and a wall that had been cleared of the thorns and trees smashed into a large hole, which could be seen clearly through the telescope.
