When Xiao Ming received the battle report about Manila, it was ten days since the war happened.

After carefully studying the details of the war papers, he frowned deeply. First of all, during the landing operation, the Dutch dug a deep trench, which even required the Dutch to step on the bench to put his head out of the trench.

This kind of trench reminds him of the trench in the Contemporary World War I, which was used by both sides to confront each other.

And the node of this deep trench is the emergence of machine guns and the increase of artillery power. Now all this seems to be happening again. The only thing to be thankful is that even if there are trenches in the west, there are no machine guns and guards' guns, otherwise the war will really become meat grinder.

He was not surprised that the Dutch used fire hedgehog to fight back imperial soldiers, causing more casualties, because a normal commander would think of this method.

However, if the deep trench and this shooting method were used, it would still be a headache when attacking the fortified positions. Of course, he believed that the imperial soldiers would surely win the final victory, but the casualties would also be relatively increased, which he did not want to see, because now any soldier is extremely precious.

After all, the Empire now has a large market. The occupied Koryo and Kingdom need garrison, and the colony also needs soldiers to maintain. The aborigines there are still civilizations in the barbarian era, and they will not reason with you at the negotiation table. The tribal leaders may declare war on you at any time depending on their preferences.

Besides, the war between the Empire and tsarist Russia on land has not really started, and the regional situation there is more complicated after crossing the Tianshan Mountains. Whether it is Iran in Persia or Afghanistan known as the durani Dynasty, or the huge Ottoman Empire, it is not easy to deal with. With a tsarist Russia, it will become a powder keg at any time It's going to blow up.

So when he chatted with Yue Yun, he mentioned his own idea, that is, to slow down the pace of expansion. Compared with the colonial system established by Europeans more than 200 years ago, he did it in just a few years.

Now he is faced with this problem. A large territory has been laid down, but the above construction is almost zero. In this way, these lands can not provide any help to the economy of the Empire, which is not pleasant to see.

Now every war is a huge consumption of bullets and ammunition. It is true that a large number of domestic copper mines can meet the current use, but it is a fool not to dig resources in the hard fought territory.

Moreover, the Empire now has mature armored ship construction technology, and the next step is the construction of large steam merchant ships. In this way, the Empire's maritime transportation capacity will grow explosively, which will make it easier for overseas resources to be transported to China.

More importantly, even if he defeated Nanyang's Western forces, he could not land in Europe to fight against Europe.

If it comes to landing operations, the war potential in Europe is still terrible. Trench warfare will turn the war into a protracted war, which he can't afford.

Therefore, the next war is still the colonial struggle and the Maritime War in the process of establishing maritime hegemony.

Thinking of this, he gave Yue Yun an order to destroy the Western warships in the Indian Ocean after he captured yagda.

This time, together with Yue Yun's war report, there is also information provided by Wang Xuan. He has learned that Western forces are gathering in India to launch a war to recapture XINJIAPO, and at the same time to prevent the empire from occupying India.

Only in Xiao Ming's view, Westerners once again misjudged what he might do.

With a group of armored ships, he won't run to confront them head-on and want to attack new Jiapo. At least their warships should be able to reach new Jiapo. Under the ocean hegemony of the Empire, it's a dream to attack the colony of the Empire. And the soldiers in India are waiting for ships to pick them up indefinitely.

Is evil ground thinks, at this time a burst of footstep sound suddenly rings out.

After a while, Qian Dafu looked at Chen Qi and went to the imperial study. After a salute, Chen Qi said, "emperor, the improvement of mortar has been completed. The next official specially came to report to the emperor."

"So fast." Xiao Ming was slightly surprised, and then smile, "yes, yes, today's soldiers fighting in Nanyang need this gun."

After that, he got up and walked out, "go, I'll see the effect."

Chen Qi smiles to follow, to the military workshop, he let the military factory technicians will be a short gun out.

"Emperor, this is the improved mortar. Now this mortar no longer needs two people to carry, and one soldier can carry it." Chen Qi pointed to the green coated short tube gun in front of him and said.

Xiao Ming nodded with satisfaction. In fact, mortar is the predecessor of mortar, which belongs to curved gun.

After the guards artillery appeared, he asked Chen Qi to improve the mortar. Now the mortar has the appearance of mortar.

"Emperor, this mortar gun now weighs 9.4kg, its frame weighs 5.8kg, and its shell weighs 2.18kg. Its effective killing radius is 17.8m, its maximum range is 2000m, and its caliber is 82mm. It's good to attack the enemy hiding behind the obstacles." Chen Qi said with a smile.In fact, he wanted to improve the mortar before, but the quality of alloy steel at that time was not good. Now with the emergence of electric power, the chemical institute uses pressure condensation technology to produce pure oxygen, which greatly improves the quality of oxygen blowing in electric furnace, and thus improves the quality of refined steel.

"The most important thing of mortar is shell. Is this shell qualified?" Xiao Ming did not immediately praise Chen Qi, but continued to ask.

Chen Qi said to the technician at this time, and then a box of mortar shells was moved in front of him.

Xiao Ming picked up a artillery shell and observed it. The firing of the mortar is different from that of the guards.

In short, mortar firing depends on the quality of the shell itself to make the primer hit the firing pin at the bottom of the barrel. When the primer is fired, it ignites the basic charge tube at the tail of the shell. In this way, the shell can shoot far away with the power of smokeless powder explosion, and then use the fuse of the warhead to touch the bottom to ignite the explosive, and finally explode.

Because of this principle, mortars are more difficult than ordinary shells. They are mainly composed of shell body, tail, basic charge tube at the bottom and fuse. At the same time, the shell body also has a closed air ring to make the shell completely fit with the barrel. Now Xiao Ming's shells are in line with the standard of mortars.

After tut tut tongue, Xiao Ming laments that the industrial capacity of the Empire has really improved by leaps and bounds. Now many technical bottlenecks in the crystal of science and technology are disappearing.
