Taking advantage of the last rays of sunset, Luo Chen directly asked people to move out ten catapults and eleven ballistas.

"Your Highness, this is ......"

After Zhao Shi'an saw it, his face was immediately stunned, his eyes were completely attracted by the catapult, and then he looked at the ballista, his face was very excited.

Luo Chen laughed: "This catapult has a range of 1,000 steps, and a ballista has a range of 1,200 steps, which is amazingly powerful and extremely lethal!" ”

"A thousand steps!"

Emperor Xia and Zhao Shi'an were both surprised: "Are you sure it's a thousand steps?" ”

Emperor Xia stared at Luo Chen tightly, although he didn't know where this kid got the catapult from, but at this moment, it was definitely a big killer weapon to be equipped!

"Of course, a conservative estimate, about a thousand steps!" Luo Chen nodded without hesitation, this is a product of the system!

"Haha!" Zhao Shi'an was excited: "I also have a catapult in Daxia, but the range is only about three hundred steps!" ”

Xu Chang was also shocked, and even a little unconvinced, and said in a lost voice: "Even Daqin's catapult has a range of only about seven hundred steps!" ”

"Haha!" Luo Chen laughed: "It is imperative to have people transport all the stones to the city wall immediately, and tomorrow, smash them fiercely!" ”

Xue Rengui nodded: "Yes, ten catapults are definitely a big killer in the defense of the city." ”

"Your Highness, I don't know how powerful this ballista is, it can really shoot 1,200 steps?" Xu Chang looked at the eleven ballistas and asked in disbelief.

Luo Chen nodded and laughed softly: "Since you are all very curious, then we will know as soon as we try it!" ”

Luo Chen asked people to take out ten giant crossbow arrows, put them on the ballista cart, and turned the wooden handle, and the cow tendon was slowly pulled apart!

"Your Highness, there is a tree over there, about seven or eight hundred steps away from here, why don't you use that tree for a try?" Chen Qingzhi pointed to a bare tree not far away and said.

"Good!"

Luo Chen slowly turned the body, looked at the tree, and after aiming, the corners of his mouth curled slightly: "Look at it!" ”

"Bang!"

"Whoosh......"

The bowstring catapulted violently, making a loud noise, and ten giant crossbows roared and burst out, shooting directly at the tree.

"Puffy!"

With a soft sound, I saw that the tree fell in response to the sound and broke directly into two!

Not only Xia Huang and the others were stunned, but even Luo Chen was frightened, I am obedient, this ballista is so powerful!

"Good! Good! All right! Emperor Xia clapped his hands and shouted three times in a row, "With these two sharp weapons, you can make Nanban cry for a while, but unfortunately, the number is ......."

"Yes! If there is a hundred and ten crosses, directly against the Nanban, where is the need to form an alliance! Zhao Shi'an sighed lightly: "It's a pity! ”

Luo Chen smiled lightly and said: "There will be, the strength of a country is not only reflected in the army, but more importantly, whether the treasury is full and whether the people are rich, including scientific and technological innovation!" ”

"What is scientific and technological innovation?"

Looking at Zhao Shi'an's bewildered look, Luo Chen's face suddenly turned stunned: "Okay! This force is not pretended! ”

Luo Chen smiled and explained: "Technology is the so-called miraculous skill, take this ballista as an example, which of my Great Xia's ballista is stronger or weaker against the bow and arrow of the Southern Barbarians?" ”

"Besides, this catapult, my Great Xia's catapult is a thousand steps, Daqin's is seven hundred steps, and our army's stones can completely smash his catapult!"

Looking at Emperor Xia and the others thoughtfully, Luo Chen continued to speak: "These are all classified as strange and clever by the famous Confucian families, but it is precisely these strange skills and tricks that can change the fate of a country!" ”

Luo Chen watched everyone fall into deep thought, and did not bother with words, and after a while, he spoke: "In the future, I will establish a medical school, an engineering college, and a business school, including a martial arts school, and use these colleges to cultivate talents for the country, and recruit talents from Kyushu into the court, so why worry about the country's prosperity!" ”

As he spoke, he talked a little too much, and taught the skills of using the ballista and catapult, and Luo Chen went back to rest!

……

Early the next morning.

Several generals took turns to be on duty overnight, and they were all on the city wall at this moment.

"I didn't expect that overnight, the barbarian army had already rested!"

Zhao Shi'an looked at the heavily guarded barbarian army camp not far away, and his face was very solemn.

"Even if our army beheaded 50,000 enemy thieves yesterday, there are still 350,000 now!" Xue Rengui let out a long sigh: "The real battle will only start today!" ”

Luo Chen looked at Xue Li: "Can you attack with fire?" ”

"No way!"

Zhao Shi'an shook his head directly and said, "Now that the wind is from south to north, the fire attack can't burn them at all!" ”

"That's only a fight to the death!"

Luo Chen shook his head lightly, his eyes were stunned: "Although it is good to defend the city wall, it still needs to be flexible!" ”

……

About half an hour later, there was a commotion in the barbarian camp, and I saw a group of men and horses rushing out of the camp, led by the barbarian emperor.

"Sons and daughters, siege the city!"

At the sound of an order, hundreds of thousands of troops rushed one after another, fearless to death, rushing towards the direction of the city wall: "Release the arrows!" ”

Xue Rengui shouted, and suddenly, the soldiers on the city wall released arrows together, and a rain of arrows shot towards the barbarian army.

"Use the ballista, fight the shield soldiers!"

Luo Chen's eyes froze, looked at a group of shield soldiers, and said in a low voice.

"No!"

"One!"

"Two!"

"Shoot!"

Suddenly, eleven ballistas shot out one hundred and ten giant crossbows, shooting towards the shield soldiers!

"Poof!"

A rain of blood drifted by, and I saw those crossbow arrows shoot directly through the shield, nailing several soldiers behind them together!

A brute's face changed dramatically, and he looked in disbelief in the direction of the city wall.

"That's it, shoot me!"

Luo Chen nodded with satisfaction, took out the Dragon Bow, and shot towards the barbarian generals.

The Barbarian Emperor stood on a high platform in front of the camp, looking at the battlefield in front of him, his brows furrowed slightly.

"Meng Su, have you seen it, what kind of weapons are those giant crossbows shot by the Xia army?"

Seeing the terrifying power of those giant crossbows, the Barbarian Emperor couldn't help but feel a little creepy, and pierced through the shield and shot through a few people again, such a sharp weapon was simply unheard of.

Meng Su's face suddenly turned surprised, and his eyebrows tightened: "I don't know, it's just that there shouldn't be too many weapons like this, it seems that there are only a dozen of them, and they can't affect the pattern of the entire battlefield!" ”

The Barbarian Emperor nodded, with a hint of fierceness in his eyes: "When the end of the world is broken, we must let the Great Xia blood debt be repaid!" ”

……

"Almost!" Luo Chen saw that the barbarian army was only a hundred meters away from the city, and the corners of his mouth curled slightly: "Catapult, start!" ”

The ten catapults had already been positioned, and Luo Chen gave an order, and a piece of boulders of dozens of catties was placed on it.

"Smash me farther away, get ready!"

"Put!"

At the sound of an order, all of a sudden, ten boulders rose into the sky, and a brute was rushing forward, and suddenly, an exclamation came, and the barbarian suddenly raised his head......
