Gao Gong fell into contemplation at this time, this Qingzhou City is not easy to fight, if you use people to pile up, you will inevitably suffer heavy losses, and the gains will outweigh the losses when the time comes, if you bombard with artillery battalions, the enemy also has artillery!

"Withdraw!" Gao Gong opened his mouth and ordered!

It's not easy to fight now, let's withdraw the troops first, and discuss it with the generals!

After the order to retreat spread throughout the army, the 170,000-strong army began to retreat five kilometers, set up camp, and make fires for cooking!

"The Qin army has withdrawn, haha, we won!"

"Long live the Canglan Empire!"

"Long live the Canglan Empire!"

When the Canglan army saw the Qin army retreating, they all shouted excitedly!

And Liu Danfu still frowned, his expression was solemn, the Qin army retreated, but it did not mean that the Qin army gave up attacking Qingzhou City, and the third prince was captured alive!

Time passed slowly, and three days passed in the blink of an eye!

Great Qin Empire, Xianyang City, Ordnance Bureau!

"Your Majesty, this is the most advanced artillery developed by the Ordnance Bureau, called the Flying Elephant Cannon, the Flying Elephant Cannon's various properties far exceed the Tiger Cannon, the Flying Elephant Cannon has a range of four thousand meters, a caliber of 120 mm, and a lethality of thirty meters, but it is a little heavier, a thousand catties!" Hua Du, director of the Ordnance Bureau, pointed to a black cannon and said.

This cannon is even larger than the Tiger cannon, with a length of five meters and a long barrel!

"Yes, I didn't disappoint, immediately mass produce and equip the whole army!" Zhao Cheng put his hands behind and said with great satisfaction.

Gao Gong sent him a letter yesterday, saying that the city wall of Qingzhou City is equipped with a large number of artillery, the performance is similar to that of the tiger cannon, and the firing range has reached 1,000 meters.

As soon as he learned about this, he came to the Ordnance Bureau to see if he had developed advanced weapons to restrain the Canglan Army, and the result was that there were really flying elephant cannons, and all kinds of performance were completely explosive tiger cannons!

Compared with the Flying Elephant Cannon, the Tiger Cannon is completely a little brother!

"Yes!" Huadu gave up!

Now that the steam engine has been successfully manufactured and the arsenal has been applied, the productivity of the arsenal has increased tenfold with the continuous supply of power from the steam engine!

Zhao Cheng left the Ordnance Bureau for a long time, went to the space-time tunnel alone, and came to Pandora!

As soon as they entered Pandora Star, the soldiers of the Qin army stationed here knelt down on one knee and shouted: "We meet Your Majesty, long live my emperor, long live, long live!" ”

"Pingshen, where is General Gao at this time?" Zhao Chengxuan raised his hand and asked.

"General Gao attacked Qingzhou City a few days ago, and he hasn't come back yet!" A soldier replied.

When Zhao Cheng heard this, he nodded, signaled that he understood, and then rode his BMW, opened the map, and went to Qingzhou City alone!

Time passed slowly, Zhao Cheng hurried and walked for most of the day, until the night, and finally arrived at the Qin army camp!

"Stop, who are you to trespass on the camp!" Before Zhao Cheng entered the camp, suddenly several Qin soldiers rushed out, holding their spears against him, and not far away, there were dozens of new-style army soldiers, using Great Qin Type 1 rifles, aiming at themselves!

When Zhao Cheng saw this, he couldn't help but smile, his high merit is good, he actually set up a secret whistle here!

"Don't know me?" Zhao Cheng said softly.

Because of the dark night, coupled with Zhao Cheng wearing a black dragon robe, some soldiers didn't recognize Zhao Cheng at all!

But after hearing Zhao Cheng's voice, the surrounding soldiers were all stunned, and then quickly knelt down on one knee and shouted: "We deserve to die, I didn't recognize Your Majesty, please punish Your Majesty!" ”

"No, you're doing a good job, if I go straight to the camp, I'll be disappointed!" Zhao Cheng said with a hint of a smile.

Immediately, Zhao Cheng entered the camp, came to the handsome tent, and found Gao Gong!

Gao Gong was a little stunned when he saw Zhao Cheng suddenly coming here, and then quickly knelt on the ground and shouted: "The last general doesn't know that Your Majesty is coming, and he hasn't come far yet, please forgive Your Majesty!" ”

"What kind of polite words did you say to me, okay, how is the battle going lately?" Zhao Cheng sat directly in the first place and asked!

When Gao Gong heard this, he told Zhao Cheng all the things that had happened in the Qin army in the past few days, and the prisoner Lang Xuan also told him.

"Oh? Less than thirty years old, already in the middle of the first class? Zhao Cheng was suddenly attracted by Lang Annihilation!

If you are less than thirty years old, if you become a first-class master, you must be one of the best geniuses, if you are enveloped, Daqin will have one more master, and your strength will increase a little!

After Gao Gong heard this, he knew that Zhao Cheng also had a heart for him, and then replied: "Your Majesty, although this person is a genius, he is not willing to join the Qin army, since he was captured, he has never said a word, and he has not eaten, if it weren't for his first-class master, I'm afraid he would have starved to death!" ”

"If you can't use it for me, then cut it off, give his head to the commander of the Canglan Army, and deter the Canglan Army!" Zhao Cheng said very dryly, his tone was very indifferent!

Zhao Cheng is becoming more and more ruthless, not for his own use, kill them all, or abolish them, such as those martial arts people who are locked up in the prison, just because they are unwilling to be the eagle dogs of the imperial court, Zhao Cheng abolished them all, locked them in the dark prison, life is better than death!

"Yes!" Gao Gong replied.

"In addition, inform the officers and men of the whole army that the city will be attacked early tomorrow morning!" Zhao Cheng began to run into the topic!

"Yes!" Gao Gong replied again!

Next, Zhao Cheng opened the system mall, and now he still has more than six million exchange points, if he buys infantry, he can buy 600,000, but Zhao Cheng doesn't want to waste the exchange points on infantry!

Merchandise: Flying Elephant Cannon Battalion!

Introduction: 10,000 artillery, 3,000 flying elephant cannons!

Price: 3,000,000 exchange points!

As soon as Da Qin researches the Flying Elephant Cannon, the system will update the corresponding troops, which is why Zhao Cheng came to Pandora!

"Buy!" Zhao Cheng said without hesitation.

"Ding Dong, congratulations to the host for spending three million exchange points to buy 10,000 Flying Elephant Cannon Camp, and the current exchange point balance: three million and four million!" The system prompt sounds.

As soon as the system spoke, 10,000 artillery and 3,000 flying elephant cannons instantly appeared in the rear of the barracks, and this scene was also seen by many soldiers, but they were all from the system, and seeing it was the same as not seeing it!

Time passed slowly, the sky gradually brightened, after dawn, the flying elephant artillery camp was placed 1,200 meters away from Qingzhou City, and the muzzles of 3,000 flying elephant cannons were aimed at the city wall of Qingzhou City.

"What is the Qin army doing, is it going to shell again?"

"Panic, the Qin army's artillery camp position is more than a thousand meters away from us, and it can't be beaten at all, if he dares to approach, our artillery won't be pretentious!"

"Don't worry, we'll just hide when the time comes, even if we hit, it's just a few shells!"
