After giving Mao Wenlong three sticks of incense on Shuangdao, and a set of financial offensives against Mao Chengzuo and Shang Kexi, Chen Xin finally left Shuangdao and boarded the warship that came to respond.

On the warship, looking at the island that was gradually moving away, Chen Xin couldn't help but show a smug smile, the secretary handed over a bowl of hot tea, and asked Chen Xin curiously, "Why are you so happy today?" The subordinates are stupid, we just opened a few business inns just now, and just now we sent a lot of condolence materials to the military leaders of Dongjiang Town. The subordinates are really a little confused. ”

Chen Xin took the tea, took a small sip, and then explained with a smile, "It has only been less than a year since Dongjiang Town came closer, and before, everyone was not familiar with each other, and they had to use their skin to infiltrate the Ming Dynasty, so it was inconvenient to make some big moves."

However, now that we have done this, and the merchant inn has opened up, we can rely on the kingdom's powerful industrial capacity, with the assistance of economic and financial means, to monopolize the trade over there, and control all the grain import channels on several islands.

This is only a preliminary measure, and when Dongjiang Town is controlled by the kingdom from top to bottom, from the military to the people, from commerce and trade to economic finance, then in Dongjiang Town, if we want to do things, it will be much easier.

Although we can't completely integrate Dongjiang Town in the short term, mastering these is not much different from completely integrating into it. ”

After this trip, the inspection work in the eastern Liaodong region was basically completed, and Chen Xin could take a boat back to the palace.

On the wharf of Port Arthur, Chen Xin was about to board the ship and go offshore, and all the officers of the navy and army in the Port Arthur came to the port to see Chen Xin off.

Today, there is also an infantry battalion of the 1st Mixed Brigade, which will follow Chen Xin back to China to replenish the troops and rest for a while.

On the mountains on both sides of the port of Arthur, a large number of auxiliaries are busy, trying to dig more fortifications before the ground freezes before winter comes.

On the hills on both sides, several forts that had been built in rudimentary form stretched all the way to the top of the hill to lie to the side. At the foot of the hill, there were ditches everywhere, and the excavated earth piled up one wall after another in front of the trenches.

Suddenly, there was a rumbling roar from behind a mountain in the distance, and just as Chen Xin heard the sound and turned his head to look, a large pile of dirt and rubble exploded there.

Chen Xin immediately discerned the type of explosion from the sound. "It's the explosion of explosives newly developed by the Ordnance Research Institute! Moreover, it is also a large dose of new explosives! Then he turned to him and asked, "What's going on?" Why did it explode? ”

Hearing Chen Xin's question, most of the attachés around Chen Xin at the port didn't know what was going on, and were busy dispatching personnel to investigate.

Fu Yan, the deputy commander of the First Brigade, who was about to return to China with Chen Xin and deal with the affairs of the first mixed brigade wheel combat unit, was standing by Chen Xin's side at this moment, and immediately spoke out to stop the busy crowd. Explained.

"Your Excellency, my subordinates know that the loud noise just now came from a newly built training ground, where our brigade built a rammed earth wall.

The sound of explosions that came out during this period of time was all comrades-in-arms of combat engineering units and other related specialties, conducting tests related to explosive weapons.

The largest proportion of these are mine-shaped weapons of all kinds.

Our army has defended some fortifications such as bastions in the past, but it has never had this kind of combat experience in defending fortified cities, so we do not have a clear concept of the combat effect of mines and other weapons in large-scale urban defense operations.

Therefore, after discussions, the brigade headquarters decided to set aside a special area for the troops to conduct experiments and make a rough list of data so as to facilitate the possible defensive operations in the future. ”

Chen Xin nodded: "I see! Then he said to Fu Yan and his adjutant, "Passing down the order, we don't have too much experience in defensive operations, and all brigades and headquarters should conduct this kind of experiment several more times, don't wait until after the battle, and then be at a loss for what to do."

This winter, the 1st Brigade will still stay in the southern Liaoning region, and Fu Yan will assist Zakdan, build the defense measures in the area around Lushun, and train the reserve troops in the defense tactics of defending the city.

This time, you return to China and bring another infantry battalion with you, and then you have to lead them to rehearse well, relying on the city to conduct a field battle, which is probably similar to the previous offensive and defensive battle in the capital.

Although you have graduated from the lecture hall, you and Zachdan still need to learn a few more things, the most important of which is that you need to learn more cavalry tactics and artillery tactics.

In the future, the number of cavalry personnel will be expanded, and the scale of the troops you need to command will be much larger than now, and at that time, the multi-arms mixed command operations will be much more southern than now, and it is better to be familiar with cavalry and artillery earlier than to temporarily cram. ”

Fu Yan beat his chest and saluted, "My subordinates remember." Your Majesty, do you think that the Houjin Tartars will really attack this winter? ”

Chen Xin looked in the direction of the north, shook his head and said, "Regardless of whether the Houjin army comes or not, we have to make relevant preparations according to the worst-case scenario, you must remember that in a battle with a strong enemy like Houjin, there is no room for luck in your heart." ”

Another adjutant beside Chen Xin also chimed in, "My subordinates also feel that our army needs to prepare early, and if Dolgon returns from the grassland before winter, Houjin will have time to prepare for the next attack on our army in winter."

According to the Liaodong people in the Lushun area, in winter, all the rivers in the Liaodong region will freeze solid.

At that time, the Tartars could use dogs or horses to pull the plough and move quickly on the frozen surface of the river. This climbing plow, the weight of the cargo that can be dragged at one time, is definitely not less than that of a horse-drawn carriage.

In winter, although the temperature is low, and there are ice and snow covering the roads and grasslands, there is also a great convenience, so in previous years, when the Golden Tartars sent troops, there were many times in winter.

However, judging from the current situation of the Houjin Tartars, their domestic affairs are not optimistic, because they suffered heavy losses in the previous battle of the Daling River, and I am afraid that the banner owners and ministers of the Eight Banners are unwilling and dare not expedition to the southern Liaoning region this year. ”
