There are only forty miles from Wuqiao to Dezhou. If it is just to form a deterrence and blockade, Bahana and Shi Tingzhu should have stationed their troops in Wuqiao. This way, not only has a city as a support, but also has the greatest room for maneuver.

However, as offensive generals, the two would definitely choose to camp at Wuli under the city, which would not only act like I am the boss, but also be at a safe distance, so there is no need to worry about the Divine Cannon that can hit Wuli in Dezhou. Moreover, from the fighting will of the Ming and Shun Army since entering the pass, the incident of Manchu soldiers appearing in Wuli outside Dezhou City is enough to make the city guardian officials abandon the city and leave.

After the cavalry of Zhenglan Banner arrived at Wuqiao, the local gentry indeed opened the city gate and told Dashun that the pseudo-official officials had escaped. Seeing the words "Return to the Emperor Ming" written on the white banner, the gentry in the county cried bitterly, as if they had great difficulties in surrendering that day.

Since the people were ready, the Manchu soldiers naturally collected food on the spot without hesitation. As a result, a new wave of refugees rushed towards Shandong, and most of them rushed to Dezhou to the south, because they heard that it had been restored by the Ming soldiers. However, some people were even more afraid of the officers and soldiers, so they moved westward.

This Manchu vanguard did not bring food and supplies. When the situation changed, he immediately drew his sword and collected it himself. Only then did the wealthy families in Wuqiao take out some of the stockpiled food and grass and try their best to comfort them.

Such a small storm also gave Xiao Mo time to calmly arrange the battlefield. After the Battle of the River, the First Battalion of Guards saw the advantages of landmines with his own eyes, so he liked to use it very much. He applied for a large amount of gunpowder and set up a mine team to be responsible for manufacturing and landfilling mines.

Although Qi Jiguang's steel wheel fire-striking and launching mines was not restored, the conventional artificial detonation of mines was already very skilled. As long as thirty or fifty were buried in front of the fortification, it would be enough to affect the charge momentum and formation of the opponent's cavalry during combat. - Although no one has seen what formation the Manchurian cavalry would be when charging.

A chest wall was quickly arranged side by side, and a cannon was arranged between the chest walls. This time, the work of transporting artillery in time was very successful. Even the Second Battalion generously sent its battalion's 17 artillery to Dezhou, and then regained the new artillery from Jiaozhou Artillery Factory.

Nowadays, the bottleneck restricting the large-scale installation of artillery is no longer the artillery production, but the transportation capacity and artillery. There are still too few soldiers who can measure ranges and carry various shooting data, and each artillery requires a pack horse, auxiliary soldiers, and logistics. Theoretically, a cannon must be fired five times on the battlefield, so that the damage caused can be equal to its cost.

Of course. If we consider the attack on the enemy's anger, the enemy might collapse if five cannons fired in one round of volleys.

With Zhu Cixuan's emergency dispatch of artillery and troops, Xiao Mo's number of artillery can be used in his hand reached an astonishing twenty-six. However, except for the five base guns, he could be arranged by him, other artillery arrangements must be listened to the opinions of the artillery department and find the appropriate artillery positions they think are suitable.

"Leave the five cannons from the base camp to them as well." Xiao Mo said generously.

"General, this..."

Is it irony?

"They are shooting artillery every day." Xiao Mo said seriously: "And look, they put artillery in front of the formation, but they pay more attention to the spacing. Learn more."

The artillery of the Artillery Bureau of the Battalion was also trained by the Firearms Department. The artillery lieutenant colonel who led the team this time had served as their instructor, so naturally there was no resistance. Moreover, this time, the Firearms Department not only brought artillery, but also artillery skills.

With the efficient manpower excavation of the East Palace, more than ten old artillery soldiers were found in the Dengzhou generation. These artillery soldiers were the remnants of the first batch of 200 Ming Dynasty artillery soldiers trained by Xu Guangqi in employed Portuguese artillery. At that time, Xilao, the leader of the Portuguese mercenary, brought 200 Portuguese soldiers and 100 followers to Dengzhou, Shandong to serve as instructors, and participated in the battle, and eventually died in battle. His moral integrity was even more admirable than many Ming scholars.

After Kong Youde caused trouble in Shandong, he fled to the Later Jin Dynasty and brought sea ships, artillery, gunners and craftsmen. Huang Taiji gave him a hug ceremony, which almost made people imagine his joy behind his back.

The fighting style of the Later Jin Dynasty therefore entered more than two generations.

These old artillery soldiers were all confidants of the governor Sun Yuanhua. Naturally, they were unwilling to leave with Kong Youde. After Sun Yuanhua's death, they did not want to die on the battlefield. So they were scattered incognito and dispersed everywhere. In the end, they could not bear the work assignments of the court's "full talent" and reported their own background, and they were freed from ordinary labor and became technical soldiers.

After obtaining these systematically trained gunners, the Firearms Division improved the operation specifications of artillery operations, and finally positioned them in eleven decomposition actions, and also improved the equipment required for artillery aiming.

"This is the gun rule." Lieutenant Colonel summoned gunners who were unable to receive training in time for the first and second battalions to conduct battlefield training. He held up two copper rulers, one long and one short, and a right angle measuring instrument. There was a quarter-circular arc ruler connected between them, with a grass code engraved on it.

"This line with a pendant is called a weight line. If you insert a long handle into the muzzle like this, the weight line will overlap with the scale on the arc ruler, which is the elevation angle of the body tube." The lieutenant colonel inserted the gun gauge into the muzzle, allowing these gunners to come over to see one by one, and they could indeed report the readings simply and clearly.

"What is this angle for?" the lieutenant colonel asked and answered: "Look at the nameplate hanging on the cannon cart. There is a table on it."

Everyone squeezed over and saw a table hanging under the cannon cart, which listed the range of this cannon under fixed-loading gun medicine and standard projectiles, at various elevation angles. Originally, this was what I knew after the test fire when I was preparing for the position before the war. It was more like a directional mine than a gun.

Now, when each gun leaves the factory, the Firearms Department uses it to shoot the target, measure the relationship between distance and elevation angle, and customizes the firing table. This is equivalent to giving each gun an additional ID card, which also allows the battalion artillery to use it, eliminating the test firing before the battlefield.

The artillery soldiers were all excited. It was obviously much easier to use this method than to knock on the ground foolishly. Even when they arrived at an unprepared battlefield, they could fight as soon as possible, and obviously had a greater sense of existence.

"Because the error of the eye-skipping method is still too large, it is more stable to measure the battlefield when conditions allow, and mark the distance with white or other things." Lieutenant Colonel explained.

The engineers pushed the measuring stroller and used a rope ruler to measure out fifty feet before the cannon position. Outside fifty feet, mark a marking point for easy observation every ten feet until one hundred and fifty feet.

This measurement stroller was invented in Wanli to measure the land mu. The inventor was Cheng Dawei, the author of "Algorithm Tongzong" and the great mathematician. It started to be promoted and used in Wanli. Until today, there are still a large number of physical objects, as well as complete sets of written materials such as part drawings, assembly drawings, design instructions and modification instructions, so it is easy to manufacture in large quantities to meet the needs of various engineering. [Note 1]

After marking the distance, the engineers took out the cross in the middle of the rope ruler, turned the crank, and quickly took back the rope ruler on the ground, which was no different from the tape measure in later generations.

Zhu Cixuan rode on the horse, seeing that the artillery was ready and the chest wall was built, he knew that Xiao Mo was ready to attack the invading Donglu.

After Chen De arranged the fortification department for rush construction, he mobilized the blasting department to assist in the installation of landmines. The gunpowder mining technology that had been popularized during the Wanli period was only needed to make a slight change to use local mines.

"Your Highness, these Eastern Captains are not coming, which is really a waste of time." Chen De arranged the work of the engineering camp and rode his horse into the circle of officers behind Zhu Cixuan.

Although other generals and schools were dissatisfied, they could not resist Chen De's thick-skinned face. Min Ziruo knew Chen De early in the morning and would not stop him. Moreover, the horse was an elegant animal after all. He would move to give up his post when he saw his fellow students coming. This made Chen De come up to meet the prince as he wished.

Zhu Cixuan smiled and said, "How is the project progress?"

"It's still a bit slower." Chen De said: "But if it's faster, I'm afraid there's nothing I can do. After using the rammed earth truck, it's almost reached its limit."

"If you want to do a good job, you must first sharpen your tools. Tell me more about what you need. Sometimes they don't know what others lack. If you really want, it might be easy to solve it." Zhu Cilang said with a smile.

"Just make the quarrying and gravel stuff, and it can free up a lot of people." Chen De sighed again, "Your Highness, I am so worried that I can't sleep all night."

ps:

Note 1: The complete set of written materials for Cheng Dawei invented the measurement stepper was still preserved intact today, so we can know that Cheng Dawei's working habits are very good. Therefore, Xiaotang can be logically derived-
