The fighting on the northern border has not stopped for a day.

The fifth day of the junior high school guarded the Yanmen Pass, which was regarded as protecting the common people in the pass, but the vast area north of the Yanmen Pass fell into the whirlpool of various guerrilla and counter-guerrilla attacks.

The entire Xuanfu Datong territory was full of skirmishes.

The arrival of the Gaojia villagers changed the situation here. The Ming officers and soldiers who were originally hiding in the cities of Xuanfu and Datong, after hearing several good news in a row, finally mustered up the courage, walked out of the city, and began to try to clean up the ranger team of Jiannu in the field.

As a result, skirmishes took place more frequently and more intensely.

The situation of guerrilla warfare and guerrilla warfare has also become more complicated.

If there really is a god who puts arrows in the sky, you will find that the entire Xuanda area is full of red, blue, and colorful arrows, intertwined to form an incomparably complex picture that can make people dense and phobic.

Jiannu encountered the battles of the Gaojia villagers, and lost every battle.

But when they encountered Ming officers and soldiers, they were able to win often.

As a result, the battle report that Huang Taiji received was "There are victories and defeats, and the two sides have fought back and forth", "Although our army has suffered losses, the Ming army has also suffered heavy losses".

Huang Taiji couldn't help frowning: "Da Ming is still very strong, and it is not yet the time for us to enter the Central Plains. That's it, it's almost enough to grab, collect the troops! Let's go back to the Northeast."

In the seventh year of Chongzhen, the battle of Jiannu invasion that occurred in Xuanfu Datong finally came to an end......

Gaojia Village This Village!

Bai Gongzi's experimental vehicle No. 3 had just slowly driven out of the Gaojiacun Military Factory.

Gao Yiyi, senior technical chief engineer, was pointing to the brand-new No. 3 car, and introduced to Bai Gongzi with his eyebrows: "Bai Gongzi, look...... This is the number three car, which was built at your request. In order to prevent the front face from being smashed again, I added an iron armor directly in front of it, and two more ramming horns on it."

Bai Gongzi looked at it, and the front face of the No. 3 car was so ugly that he wanted to cry. Gao Yiyi didn't know what the aesthetics was, and a huge shield-shaped iron plate was directly installed on the front face of the No. 3 car, and there were two cone-shaped protrusions on the board.

Bai Gongzi couldn't help but laugh: "You call this a collision angle?"

Gao Yiyi: "Isn't it?"

Bai Gongzi: "This is basically two iron cones in front."

Gao Yiyi: "The real killing weapon is simple and practical."

Bai Gongzi: "If such a big car hits the enemy, how can the enemy be immortal? Is there a big difference with this ramming angle?"

Gao Yiyi: "Isn't there a big difference between puncture damage and blow damage?"

Bai Gongzi: "......"

Speechless for a while!

After a long while, Bai Gongzi said weakly: "If you want to pierce and hurt, you might as well install two fire guns here, what do you think?"

A light bulb on the top of Gao Yiyi's head "snapped" and lit up: "Oops, yes! It's better to put two cones than two firearms! Bai Gongzi, you are really a genius."

Bai Gongzi Forty-five raised his back to the sky: "You don't need a genius to think of this kind of thing, right?"

Gao Yiyi: "After installing the firecracker, the driver can't drive again and fire the firecracker, right? A soldier with a specialized fire gun is needed in the car...... You need to have a second passenger seat next to the driver's seat."

Bai Gongzi: "Well, that's right. There is only one co-pilot, and it is not possible to use two firecrackers at the same time, so it is enough to install one firecracker. Loading a moving car is cumbersome, is there any convenient means of reloading? For example...... Spinning things that feed bullets into the chamber of the gun in turn? This is a mechanical thing, Wang Zheng is very good at it, I have to ask him."

Inspiration is here! Here it comes!

Bai Gongzi cheered, "I have to go back and draw a new drawing."

Gao Yiyi: "Huh? Then you don't want this No. 3 car?"

Bai Gongzi laughed: "Don't! This No. 3 car is useless, so I'll give it to you for fun."

Gao Yiyi: "Wow, how

How can this be? This is something that the village treasury has allocated money to build, and many craftsmen have worked hard to build it for many days before it can be made, and the cost is huge, so don't abandon it without saying a word."

Bai Gongzi didn't care, he ran fast, and disappeared in a blink of an eye.

Gao Yiyi couldn't cry or laugh, this kid is really a gust of wind and rain.

He turned his head to look at the experimental vehicle No. 3, what can I do?

Gotta go to the steward Tan Liwen to report.

The chief steward 32 has gone to Shanxi with a large number of technicians to support the construction of Shanxi, and now Gaojia Village is in charge of the No. 2 person, Tan Liwen.

Gao Yi quickly found Tan Liwen, and saw that he was frowning: "Damn, a steam pump is needed over there in Qingcaogou, but it has been cloudy for the past two days, and the sun car can't run." It's too hard to pull this thing in a horse-drawn cart or bullock cart, so what should I do?"

Gao Yiyi came in at this time: "Steward Tan, Bai Gongzi ...... just now"

He honked and recounted what had just happened.

Tan Liwen's eyes lit up: "Experimental vehicle No. 3, now in your hands?"

Gao Yiyi: "Yes!"

Tan Liwen: "It can pull the steam pump, right?"

Gao Yiyi smiled: "Of course it can be pulled, it's a steam engine, just like the engine used in a big train. It's a little smaller, but it's a lot more powerful."

Tan Liwen was overjoyed: "Great, I removed all the useless armor on this car and set off lightly. Install a tow bucket in the back of the car, put the steam pump in the trailer, and pull it to the grass ditch."

Gao Yiyi: "Drag?"

Tan Liwen gestured with his hand: "Yes, drag the bucket, it's like this...... Well, a large dustpan that is usually used for washing vegetables. Wouldn't you be able to make an oversized dustpan and put it in the back of the cart?"

Gao Yiyi: "Let's play with Experimental Car No. 3 like this, will Bai Gongzi kill us?"

Tan Liwen: "He said he didn't want to! This experimental car No. 3 was originally built at the expense of the village treasury, but now he doesn't want it, so it's good to take it back from the village treasury and deliver goods to the village?"

Gao Yiyi thought about it carefully: "It seems to make sense."

So, it didn't take long for the experimental car No. 3, which had removed its armor and installed a large cargo bucket, to set off towards Qingcaogou......

Everyone was surprised to find that this thing seemed to be very good for delivery.

It is not affected by the sun and can be driven at any time and at any time, even at night as long as there is coal burning. It perfectly makes up for the application scenario that the sun car given by Tianzun needs to have the sun to start.

Tan Liwen was overjoyed and made a large amount of money: "The village treasury paid for the mass production of experimental vehicle No. 3! In the future, all such vehicles will be equipped with large dustpans to transport goods, and they will be called 'wagons'."
