"Boom, boom!" Under the indiscriminate fire of the artillery, a large part of the intact city wall to the left of the city gate was fired into a sieve by the cannons. Like the wall on the right, more than half of it has collapsed.

The walls of the sand, earth and stone were too fragile to withstand the heavy blows of the cannons.

Cheng Yanjin was very satisfied with these two rounds of shooting, and commented with a smile: "Not bad! Not bad! It is really a siege weapon, and it didn't take a single soldier to coax the walls of the Gaochang royal capital to pieces. It's really refreshing! You see those Gaochang soldiers are scared silly haha! They still don't surrender obediently? Hey? What are they doing here? So why are you digging up the ruins desperately? Hum! If you have this time, you might as well inform the newly enthroned soft King Gaochang and let him surrender early! ”

Chen Fei picked up the telescope and looked at the ruins for a while, and handed the telescope to Cheng Yanjin with a strange expression. "Uncle Cheng, you'd better take a look."

"What's there to see? Isn't it just a bunch of monkeys? Cheng Yanjin disliked it, but his hand was still very honest, and he picked up the telescope and looked over there...... "Huh?" How did the people who dug it out wear so graceful and luxurious one by one? Don't you look like an ordinary soldier? ”

Xue Wanjun also took the binoculars and looked at them, and then his face became as strange as Chen Fei. "General, the one who dug up from the rubble... I'm afraid it's Ju Zhisheng, the newly enthroned king of Gaochang, right? ”

"What?" Cheng Yanjin rubbed his eyes, picked up the binoculars and took a closer look. I saw that at the edge of the ruins, Gaochang's soldiers and a group of gorgeously dressed people hurriedly pulled a man in royal clothes out of the ruins, patting the dust off his body for him and inspecting his injuries. If it weren't for the king, who would be so enthusiastic about him?

"I'm X!" Cheng Biting Jin scolded his mother, "This king deserves to be good, what is it to go underground?" Looking for abuse? ”

Chen Fei wiped his sweat and said speechlessly: "Uncle Cheng, I'm afraid it's not that he is looking for abuse, but that he happened to be on the city wall just now, and was bombarded by our cannons to the ruins." ”

Cheng Yanjin thought about it, and then laughed: "Hahaha! Regardless of how he got down, now let's get down to business, what about the heralds? Come forward to me, shout to the group of gorgeously dressed people, and tell them that there is still a quarter of an hour left, whether to fight or surrender, let them decide for themselves! ”

A herald stepped forward, rode to the foot of the city wall, and restored what Cheng Yanjin had just said to the ministers and the king of Gaochang.

It didn't take long for the soldiers to return in high spirits. "General, they've descended!"

"So fast? No resistance at all? Cheng Biting Jin touched his chin, he seemed to feel a little unpleasant. Damn, I originally wanted to kill him, but since it has been lowered, it can't be forced, so as not to be like Hou Junji's ......."

"You! Then go over and tell them that since it has fallen, you will put down all your weapons for Lao Tzu and obediently go out of the city to disarm! Cheng Yanjin pointed to the soldier who had just come and gave the order.

The soldiers had a very high executive ability, and ran to the ministers of Gaochang to convey instructions, and after a while, they saw the Gaochang soldiers coming out of the city in a neat row, stacking the swords and armor in their hands on the open space, and then standing aside, looking at the Tang army a few hundred meters away with some trepidation.

Seeing this, Cheng Yanjin and Xue Wanjun took 20,000 people to collect the surrendered Gaochang soldiers, leaving Chen Fei and 10,000 soldiers behind to avoid accidents, and they were caught off guard and couldn't react.

Gao Chang really fell, and this time even the main battle faction had no objections. The enemy could easily collapse their walls from a few hundred meters away, the gap was too great for it to be fought. Surrender can also reduce casualties, so as not to destroy the lives of Gaochang.

The incorporation of Gaochang's soldiers was very smooth, down to the soldiers, up to the king, all of them were controlled by the Tang army. However, there are still a few small cities and villages in Gaochang that have not been surrendered, Cheng Yanjin became a shopkeeper, gave Chen Fei 10,000 soldiers and horses, and handed them over to him, and he took 20,000 troops and Xue Wanjun to "enjoy life" in the royal capital.

Chen Fei raised his middle finger and silently cursed them ten thousand times in his heart, but he still obediently led his troops to collect all the remaining cities.

The royal capital has been surrendered, and these small cities are not very dare to continue to resist, so he did not spend much effort to make these small cities lay down their arms and surrender.

It's just that after the incorporation of these small cities, there is an even more serious task waiting for them - the Silk Road in the Western Regions!

That's right, Li Shimin sent troops to attack Gaochang, and it was part of the reason why Gaochang was unpleasant, and part of the reason was that he wanted to tightly control the Silk Road in his own hands! Gao Chang is just the first step in his journey!

Li Shimin has always been an ambitious person, and what he wants to create is not only the glory of the Qin Emperor and the Han Dynasty, but a super world that surpasses any dynasty. What Emperor Qin and Han Wu didn't do, he had to complete!

The Beiting Protectorate was the first step on his journey, and since the Northern Regions had been leveled, his eyes were naturally set on the Western Regions. Although the Western Regions are desolate, the transnational Western Regions is a new world, where there are completely different customs, countless jewels and gold, as well as never-before-seen natural treasures, Li Shimin's ambition is to open up the Western Regions, and then recuperate and conquer the West!

I have to say that the idea is crazy, but it is precisely this madness that makes a mythical dynasty!

Chen Fei returned to the Gaochang city wall with his soldiers and horses, looked at the military flag with the word "Tang" planted on the city wall, and took a deep breath.

The pace of Datang's expansion is getting closer and closer, does he want to ...... What to do a little more?

After returning to the royal capital, Chen Fei explained his work and left alone. There are many things to deal with the aftermath, but it has little to do with him, he is now sitting on the ruined city wall, looking at it from a distance, and thinking that he is in a daze at the setting sun.

When you walk in, you will find that he is tinkering with a few thunderbolts, and there are several shells stacked next to the thunderbolts.

After two days of tinkering, Chen Fei asked the craftsmen of the Qi Workshop to recreate several oval shells from the pig iron furnace, the inside of which was hollow, leaving a small round hole in one direction.

After the cannonball cooled, the cannonball was filled with gunpowder, and then a hollow wooden pipe was found, which was built according to the style Chen Fei said, and then the inside of the wooden coffin was filled with gunpowder with a high density, and then the top was sealed with a special material, and this wooden pipe became a simple cannonball lead.

Chen Fei first asked people to light the wooden coffin and try it, calculated the time for the lead to burn, and then created a wooden pipe of the same specification, marked with a scale, and inserted it into the cannonball with a special method to fix it.

In this way, a "explosive" cannonball that appeared in the Middle Ages was preliminarily completed.

As for the power of this thing......

Chen Fei glanced at it and pulled out a soldier who looked more unlucky. "Do you know how to shoot?"

The soldier puffed up his chest and shouted, "Yes!" ”

"Good! The motherland needs talents like you, give you torches, and later go to light the shells. Chen Fei smiled and handed the soldier a torch, with such a hint of insidious cunning in his smile...... ()
