Xi shan.

The previous workshop is gone.

All the wood and iron were dismantled and turned into fortifications.

From the foot of the mountain to the top of the mountain, the whole West Mountain is five steps, one post, ten steps and one sentry, and it has been completely built into an iron bucket fortress.

Originally, according to Su Yang's assumption, it would take at least more than a month to complete this step.

After all, there are only so many people in the Xishan army, except for the armor soldiers who have to patrol and guard and the soldiers of the Shenji Battalion who have to train hard, the soldiers who can really participate in the construction of the fortress are only about 3,000 people.

However, he forgot one point, that is, the tens of thousands of workers in the Xishan coal industry.

When these common people and workers learned that an enemy army was coming to attack Xishan and try to seize their homeland, they immediately responded to the call enthusiastically, and spontaneously went to build fortifications, refusing to even take their wages.

Since the establishment of Xishan Coal Industry, the people within a radius of ten miles have relied on working in Xishan Coal Industry, and their lives have been much better than before, not only can they be fed and clothed, but also can accumulate a lot of surplus money, which is something they never dared to think about when they used to cultivate the land.

And those workers in Xishan Coal Industry have long regarded Xishan as their home, as a home where they can live a lifetime, and naturally cannot be destroyed and violated by others!

This battle to defend Xishan is no longer a matter of Su Yang alone, nor is it the matter of the Xishan army, but the business of all Xishan people!

Xu Xiang also saw the people's will from this matter, and proposed that Suyang form a Xishan militia team.

Originally, Su Yang didn't plan to do this, because these workers were not soldiers after all, and they had never been on the battlefield to kill the enemy, and once they were really involved, it would be no different from cannon fodder.

But in the current situation, he can't help but agree.

Everyone in Xishan knows very well in their hearts that once Ping An senses that something is wrong, he will definitely lead a large army to kill Xishan!

At that time, the enemy army that Xishan will face will not be just 5,000 light cavalry, but tens of thousands of elites of the Southern Army, as well as Ping'an, the son of Taizu and a famous general in the world!

Because of this, Su Yang finally pinched his nose and agreed to Xu Xiang's suggestion, and let him transfer the young and strong among the Xishan workers to form a Xishan militia team of 5,000 people, and conduct drills with the soldiers, hoping to play a role in the next battlefield.

And Su Yang himself was not idle, and personally devoted himself to the construction of the fortress, and he didn't close his eyes for several days and nights.

He knew very well that Xishan's soldiers and horses could not stop the Ping'an army at all, let alone the famous general Ping'an.

But once the West Mountain is broken, not only will they die, but the fate of these West Mountain workers will not be much better, either they will be killed or reduced to hard slaves, otherwise he would not have refused Zhu Gaochi's invitation and risked staying in this West Mountain.

Now the only thing Su Yang can do is to build Xishan into a war fortress, even if Ping An really leads the army to attack, he can rely on these fortifications to hold on for a while, and wait until Zhu Di, the king of Yan, leads the army back to help, then there will be a glimmer of life!

Although Su Yang has never fought, he has never eaten pork and has never seen a pig run, all the bunkers and secret posts have been arranged, and he has even dug one trench after another on the plain at the foot of the mountain, in short, how to come safely.

After all, this is a life-saving measure, and you can't be too careful.

At this moment, Su Yang was still inspecting, but Ma Sanbao hurried over.

"Childe, get it out!"

"Huh? What came out? Rummy Gun or Three-Eyed Gun? ”

Su Yang had already left drawings in the firearms workshop, including the Lumi gun, the three-eyed gun, the tiger squat gun, etc., and the performance was far superior to these inferior fire-digging sticks used by the Ming military.

It's just a pity that the level of firearms craftsmen is not high, even if there is a high reward incentive, they only tinkered with the tiger squat cannon and mass-produced it, but the firearm has not made phased progress!

"Childe, it's a three-eyed gun!"

Three-eyed guns?

Su Yang's face was happy, but it was understandable.

After all, compared with the current fire-digging stick, there are not many improvements in the three-eyed gun, so the craftsman can make it out.

As the name suggests, the three-eyed gun has a total of three muzzles and three barrels connected, and can be freely selected to fire once or three times, but because the gun barrel is short, it cannot be aimed at three points and one line, and the reloading speed is extremely slow, and the range is not far, only thirty or forty steps.

But the key issue is that the Three-Eyed Gun can be used as a weapon for close combat!

That is to say, after a round of firing, Lao Tzu directly did not load ammunition, and used the three-eyed gun as an iron rod!

By the end of the Ming Dynasty, almost all towns in eastern Liaodong used three-eyed guns as standard equipment, and both cavalry and infantry were generally equipped with three-eyed guns, which shows the popularity of this thing.

To put it bluntly, the three-eyed gun is similar to the trolls of later generations, but the lethality is not as great as the trolls, but at close range, the enemy is sprayed by the three-eyed gun, even if you are wearing chain mail, you can spray it into a sieve, this is the charm of trolls!

As the saying goes, "trolls in hand, I have the world"!

Su Yang was also very happy, and immediately rushed to the firearms workshop with Ma Sanbao.

At the same time, the city of Tongzhou.

Ping'an rode a high-headed horse, stepped on the stump and broken arm all the way, and led the army into this fortified city.

The Yan army had no more than 5,000 soldiers and horses left behind in Tongzhou City, and it was difficult to resist the 50,000 troops under Ping'an.

It took only one day for Ping An to take the fortified city without any incident.

It's just that Ping An doesn't understand the arrangement of the Yan army, or he doesn't understand the approach of the Yan King Zhu Di.

Ping'an is the righteous son of Taizu Zhu Yuanzhang, who grew up with Zhu Di and other princes since he was a child, and he can be regarded as an acquaintance who knows the roots.

And after Zhu Di sat in Beiping and inherited the mantle of General Xu Da, Ping An also served as his deputy general and went out to fight with Zhu Di.

Because of this, Ping An knows Zhu Di very well, and this His Royal Highness King Yan is really outstanding in martial arts, enough to rank among the world's first-class!

Why would His Royal Highness King Yan, who can fight well, make such a risky move?

personally led the main army to Daning, just leaving some old, weak, sick and disabled to defend Beiping, can he Zhu Di really ensure that these old, weak, sick and disabled can hold Beiping?

Once Beiping City is lost, the Yan army will become rootless duckweed, and Zhu Di will definitely be defeated!

For Zhu Di, this is undoubtedly a shocking gamble that bets everything!

However, where is Zhu Di's confidence?

Why do you Zhu Di dare to gamble like this?

As soon as Tongzhou was lost, Beiping was completely reduced to an isolated city!

When he led the army to join the main army outside the city of Beiping, or did not wait for him to go to Beiping, Qu Neng would definitely be able to break it!

So, what about you Zhu Di?

Ping An couldn't figure it out, so he simply stopped thinking about it.

Seeing that there was a panic in the city, Ping An immediately ordered.

"Sun Cheng, take people to clear out the stragglers, don't disturb the people in the city!"

"General, Sun Cheng ...... Haven't come back yet? A general reminded in a low voice.

Ping An was stunned when he heard this, and then reacted.

Sun Cheng seemed to have been sent by himself to track down the Yan army scout.

"What's going on? How long has it been? ”

"Ten days!"

Hearing this, Ping An frowned.

Ten days!

Sun Cheng should have come back a long time ago!

After all, he has 5,000 light horsemen under his command, and even if he encounters the main force of the Yan army, he can retreat in time!

Even if they can't retreat, there will always be soldiers who will escape by chance, and the 5,000 light cavalry will not be wiped out!

So, what's the problem?

"Leave 5,000 soldiers and horses to garrison Tongzhou, and the rest of the soldiers will go out with the general immediately!"

Beiping West Mountain?

Zhu Di, Zhu Di, is this the back hand you left?
