Xi shan.

The surrender was not successful.

Peace also gave birth to a little anger.

He had a reason why he had to get Su Yang.

At first, Ping An was interested in Xishan because of the mysterious firearm in the hands of Xishan Yanjun.

If the royal court master gets the help of this firearm, what Yan King Zhu Di and what foreign barbarians can crush them into slag in an instant!

But after several fierce battles, Ping An captured some prisoners and learned a shocking news from them!

It turned out that Xishan not only had advanced firearms, but also had a Su Gongzi.

This person is rumored to be a high-level member of the Yan Wangfu and is deeply trusted by Yan Wang Zhu Di.

Anthracite coal helped Yanwang Zhu Di gather the hearts of the people and gather the people's popularity.

On the basis of inferior firearms, the tiger squat cannon, three-eyed guns and other battlefield weapons were improved.

All of this is from the hands of this Su Gongzi!

After learning the news, Ping An immediately changed his mind.

In any case, he must seize Su Yang and dedicate Su Yang to His Majesty the Emperor!

Such a peerless genius, it is not an exaggeration to say that it is a national weapon!

If the imperial court gets him, if His Majesty the Emperor gets him, if the Ming Dynasty gets him, what kind of prosperous era will the Ming Dynasty usher in?

Therefore, Ping An has a reason to have to set foot on the West Mountain and capture Suyang alive.

It's just a pity that Su Yang is young and youthful after all, and refuses to surrender.

Then, Ping An can only tell Su Yang through absolute force that his choice is wrong!

This time, the Ping'an army was in full swing, and more than 20,000 soldiers all attacked, frantically rushing to the Yan army's trench position.

At the same time, Ping An also used a big killing weapon, which was enough to solve the big killing weapon in the Yan army trench.

Don't you like to hide in a trench?

That's fine, just stay in there, don't come out!

With Ping'an's order, dozens of return cannons let out an earth-shattering roar.

The reason why Ping An had to wait for one night before launching a general attack was not because he gave Su Yang face, but because he was waiting for the return artillery.

Huihui cannon, also known as the Western Regions cannon, boulder cannon, Xiangyang cannon, throws stones with the machine, the lethality is huge, it was originally cast by the Mongolian barbarians when they attacked the Song Dynasty in the south, and it was used to conquer Fancheng and Xiangyang, and it created a great name.

After the Mongol barbarians were driven out of the Central Plains, these return cannons fell into the hands of the Ming army, and now they have become the big killer of the trench position of the Xishan Yan army.

As a battlefield veteran, Ping An does not lack the wisdom of war.

Although the previous attack of the Southern Army was fierce, the soldiers of the Yan Army in the trench had cover, and with the advantage of firearms, they caused great casualties to the officers and soldiers of the Southern Army!

This new combat method of the Xishan Yan Army made the entire Southern Army feel at a loss, and its morale plummeted.

Ping An thought about it, since the Yan army has a bunker to rely on, then I will destroy your bunker and see what else you can stop the soldiers of the Southern Army!

Therefore, the return artillery arrived at the Xishan battlefield.

Huge stones fell from the sky and smashed heavily on the trench positions of the Yan army.

Although these dense stones could not explode directly like the shells of later generations, with the weight and gravitational inertia of the stones themselves, the huge stones fell on the position, causing huge casualties to the soldiers of Xishan in an instant.

Many soldiers were still shooting in the trenches, not noticing the boulders whizzing and falling overhead, and they were instantly smashed into a puddle of flesh, and they didn't even have time to scream, and they were killed on the spot!

For a while, the screams were endless, and the terrible roars and wails resounded through the sky!

Su Yang's face changed drastically and he ordered a retreat, and Ping'an used the return cannon, which was something he had never thought of.

Trench positions can hold off enemies on the ground, but they can't stop attacks from overhead!

At present, they have to abandon this last trench position and retreat to the hilltop fortress, otherwise all the soldiers of Xishan will be confessed here!

"Withdraw!"

"Retreat immediately!"

Su Yang roared sharply, and fled into the fortress in a hurry with the remaining soldiers.

The Southern Army took advantage of the situation to seize the trench position and took advantage of the situation to kill the last fortress.

After Su Yang fled back to the fortress, he gritted his teeth and decided to fight back.

Pingbai was beaten so miserably, he couldn't swallow this evil breath if he didn't fight back.

After determining the direction through the watchtower, the rows of tiger squat guns adjusted their orientation and aimed straight at the return guns of the Southern Army.

Although the lethality of the return cannon is huge, it is very troublesome to load, and the boulders need to be carried to the equipment by manpower before they can be fired.

Ping'an temporarily stopped the attack, and he didn't want his soldiers to make unnecessary sacrifices.

As long as you wait until the second round of reloading is complete, you can destroy the strange-shaped fortress in front of you.

When the Mongol barbarians attacked Xiangyang, Xiangyang City had already become a strong city under the construction of the Song army, but even so, a huge strong city was bombarded into ruins by the Hui shelling, and its terrifying power can be imagined.

Even Xiangyang City can't stop the return cannon, let alone the temporary fortress in front of him?

However, the next moment, Ping'an's face changed.

With a deafening sound, a large number of lead bullet stones were shot out from the Xishan fortress in the next moment, and they smashed straight towards the rows of return guns.

"Not good!"

"Protect the return cannon!"

Ping'an's face changed greatly, and he hurriedly ordered.

But it's still a step too late.

Sun Cheng has the most say in the power of the tiger squat cannon, but unfortunately his body is already cold now.

Although the Tiger Squat Cannon did not fire the kind of shells that could explode in later generations, hundreds of lead bullets and projectiles exploded, which was actually no different from the explosion of artillery shells.

Returning to the artillery position, in the face of the dense locust projectiles shooting overwhelmingly, the officers and men of the Southern Army didn't even have time to react, they were directly beaten into a sieve and poured into a pool of blood.

It didn't matter if they died, but those boulders lost control in an instant, and they fell directly and smashed many of the return cannons to pieces.

And then the Tiger Squat Cannon fired again, only this time it was all replaced with thick stones, and it accurately hit the return cannon, smashing a lot of lever pillars.

After this counterattack, the return cannon of the Ping An Army was completely scrapped.

Seeing this situation, Ping'an's face was full of iron, and he was obviously really angry.

"Good!"

"It's so good!"

"Come on, light the wolf smoke and set fire to the mountain!"

"Ben will not believe it, you would rather die than come out!"

As soon as these words came out, the officers and men of the Southern Army showed hesitation.

This is a poisonous plan to set fire to the mountain, after all, the fire is not easy to control, and if it is not handled well, it will even implicate all the people in the Xishan area.

But right now, Ping An is obviously angry to the extreme, so he can't care so much.

Now he just needs to catch Su Yang, beat him up and bring him back to the court!

"Don't go yet!"

"Those who violate the order will be killed!"

At the same time, Songtei Guannei.

Zhu Di looked at Guo Ying with a gloomy face, eager to cut this old man with a knife.

He knew very well what danger Beiping would face, so he led his army back from Daning early.

As a result, Zhu Di never expected that Li Jinglong had already gained insight into his intentions, and sent Guo Ying and Yu Tongyuan, two veterans, to stop him for more than half a month!

It has been two months since he Zhu Di went to Daning.

In two months, will Chi'er and Su Yang be able to hold Beiping?

Zhu Di didn't know, and he didn't dare to think about it.

If Beiping is lost, then the Yan army will really be finished.

Not only his wife and children are in Beiping, but also the families of the Yan soldiers are also in Beiping.

Once Beiping falls into the hands of the Southern Army, and there is no need for the Southern Army to make another move, the Yan Army will mutini on its own, kill him Zhu Di, a chaotic minister and thief, and take his Zhu Di's head to apologize to the court!

Damn it!

Why is this happening?

Zhu Di looked at Guo Ying coldly, undisguised his killing intent.

Yu Tongyuan was already dead and was beheaded by Tan Yuan.

And Guo Ying saw that the general trend had gone, so he dropped directly.

But the news that Zhu Di got from him was desperate.

As early as January, the Southern Army had arrived outside the city of Beiping and launched a fierce attack!

In a month's time, 200,000 elite troops of the Southern Army, how can Chi'er and Su Yang defend Beiping with only 40,000 or 50,000 troops in their hands?

Zhu Di was already about to despair, and even had the idea of killing himself to thank the world.

But he didn't do it after all, but sent all the secret guards out to find out the situation in Beiping City.

The secret guard has an independent intelligence system, which is located in Beiping, Baoding, and Yongping, which is set up by Zhu Di to learn from the scouts in the army to transmit information, which can greatly improve the transmission efficiency and ensure that the intelligence is timely and effective.

Soon, the Dark Guard Commander Armor II hurried back.

"Lord Wang, Beiping is not lost!"

"The prince of the world protects the city with ice, and he has held it to this day!"

As soon as these words came out, Zhu Di was instantly ecstatic and regained his ambition.

As long as Beiping is not lost, then everything is possible!

Zhu Di couldn't help but smile, and was about to give the order to step up the march and gallop to help Beiping.

However, Jia Er's next words made him extremely angry.

"Another Jiayi sent a message, Ping An led an army of 50,000 to storm Xishan, Su Yang Gongzi is in a desperate situation, please send troops to rescue as soon as possible!"

"What?" Zhu Di was furious, "How could Su Yang stay in Xishan?" He should be in Peking at the moment, right? ”

"Prince Su Yang was unwilling to abandon the people of Xishan, and led 8,000 soldiers to fight with the Ping'an army for more than a month, 8,000 soldiers suffered heavy casualties, and even Prince Su Yang was also heavily injured, just afraid of ......"

"Pass my military orders!"

Before Jia Er's words were finished, Zhu Di had already rushed out.

"Immediately reorganize the army and target Beiping City!"

"All the soldiers marched with only dry rations, and all the baggage was handed over to the baggage battalion!"

"Tan Yuan and Zhu Gaoxu, with the two of you leading 30,000 iron horsemen to help Xishan, immediately send troops to attack in the starry night, be sure to rescue Su Yang, you must see people in life, and see corpses in death!"

As soon as Tan Yuan and Zhu Gaoxu heard that Su Yang was besieged and killed, they immediately turned over and galloped away.

Looking at the backs of the two of them, Zhu Di's heart instantly pinched together.

Eight thousand and fifty thousand, Su Yang is facing a desperate situation that is more dangerous than any of them!

"Virtuous son-in-law, you must hold on, my father has come to save you!"

Zhu Di also turned over on his horse, pulled out his long sword and looked up to the sky and roared: "Where is the Yan Jun Ruishi?"

"Wan Sheng! Wansheng! Wansheng! ”

"Expedition!"
