Shang Dequan was the only one on the open shooting range, he avoided the original trench and bunker, and stood on the flat ground on the side of the trench and bunker, and he could see everything in front of him at a glance, silently staring ahead.

Tang Haoran and the others, who were standing dozens of meters away, were all standing behind the sandbags to avoid damage from fragments, watching Shang Dequan prepare there, turning his waist, shaking his arms, and then leaning over to pick up a grenade, while quietly looking ahead, while preparing to pull the fire in his hands.

Suddenly, under the gaze of everyone, Shang Dequan took a few steps back, stood still, and stared ahead with his eyes. A moment later, he strode forward to run, sideways, threw his arms, turned around, his arms straightened, his whole body tensed backwards like a full bow, suddenly, his body opened forward sharply in rapid movement, and when the grenade popped out of his hand, his wrist buckled down with the momentum, which was a fire pulling action, and with a "whoosh" sound, the grenade flew into the sky.

A small black dot flew forward in the clear sky, flying very high and very slow, forming a beautiful parabola in the air, accurately falling below the shooting range, four or five seconds later, the grenade exploded, the location of the explosion was just where the target board was inserted, the grenade exploded after landing, and the explosion of the grenade shocked everyone on the shooting range, not only others, but also Shang Dequan and others were also shocked, and everyone was stunned.

"This, this is a small cannon!"

Wu Dingyuan blinked and shouted in surprise, the pass in the police barracks is 35 meters, which is about ten zhang...... It's really impossible to fight. Just relying on grenades to blow up the enemy's soul can be scattered.

"It's not a small cannon. It's a small cannon for everyone! ”

Shang Dequan responded. Somewhat excited, he picked up another grenade and threw it out, running, throwing the bomb, the second grenade whistled out, and there was another explosion, this time there was another round of applause, and the grenade exploded in the target pit, in other words. Dozens of meters away, he threw the bomb directly into the trench.

"Good!"

Hello, Tang Haoran took the lead in applauding, and the applause suddenly sounded on the shooting range, for the people of this era, this is the first time they feel the charm of bombing, and Tang Haoran is also the first time to feel the grenade explosion so closely, I have only seen it in movies in the past. And for Tang Haoran, who "invented" the grenade, he is undoubtedly more proud.

"A total of four were thrown, and an infantry on the battlefield carried four grenades, whether for defense or not. Attack, a few thousand grenades are enough to blow up the enemy forces in front of you......"

It's time for everyone to shout. Wu Dingyuan, who was stunned, whispered softly on the side, in the past, when the infantry marched and fought, except for a rifle and a bayonet that was not very used, there were no other weapons, and perhaps the grenades thrown by relying on the strength of the arm could only be thrown more than ten zhang, but when the guns were being fought, one side suddenly threw dozens, hundreds, or even thousands of grenades, and the war zone would immediately fall to the side with grenades.

With grenades, that platoon of guns ...... Shooting, assassination, bomb throwing, blasting, earthwork, no wonder the adults said that this bomb throwing is the five skills of the infantry, thinking in his heart, Wu Dingyuan looked at the eyes of the adults has also changed, that is a kind of admiration in the bones, in fact, the same is true for other officers in the battalion, the army has the atmosphere of the army, the adult may not be from the army, but from the compilation of the "Infantry Manual", to the writing of the shooting and assassination models, all of them are adults alone, and the adults are not only experts in training, as for this seemingly inconspicuous grenade, which was also invented by adults, is really ......

Tang Haoran, who applauded Shang Dequan's performance here, didn't know what Wu Dingyuan and others thought, looking at the smoke that spread over there, Tang Haoran turned his head and said to Zheng Tingxiang again.

"I don't think this grenade is very powerful!"

Although he was full of anticipation for the grenade, the "cannon in the hands of the infantry", he could see from the smoke of the explosion that the grenade was far less powerful than he had imagined.

"My lord, the power of this gunpowder is limited, in order to improve the power of the gunpowder, the iron shell has been increased, and it is loaded with two taels of gunpowder, and the detonator has been increased, if the iron shell is expanded, the weight will have to be at least one pound out, I am afraid that the grenade will not be thrown far by then, unless it is ......"

Listening to Zheng Tingxiang's complaints, how could he not know that in the previous hundreds of tests, he also felt that its power was insufficient, in order to increase the power, from enlarging the shell to increasing the detonator, in short, he tried his best, but these methods were all palliatives but not cures. The reason for the lack of power is the problem of gunpowder, and only by solving the problem of gunpowder can the root cause be cured.

"Unless what?"

"Unless you use the fierce yellow chlor newly made in France, which is several times more powerful than gunpowder, if you change to yellow powder, this grenade will be as powerful as the camp cannon with gunpowder!"

"Yellow Z medicine!"

Zheng Tingxiang's words made Tang Haoran stunned, 1890 was a critical period of military change, smokeless medicine and bitter drunk, TNT and other Z medicines began to replace black powder, cotton and other gunpowder, and in history, Japan just seized the opportunity of this military technological change, so as to master the technological advantage, whether it is the First Sino-Japanese War or the Russo-Japanese War, picric acid Z medicine has its power is remarkable.

"Is the technology to make yellow Z pills complicated? Can we make it? ”

Could it be picric acid Z medicine? Thinking of the shortcomings of picric acid Z medicine, such as corroding the shell and high sensitivity, after getting a negative answer, Tang Haoran recalled that he had seen the manufacturing process of TNTZ medicine on the Internet, although the process was precise, a process looked like only a reaction, a flow chart and hundreds of text explanations.

But in 1890, it was a new type of technology, although as early as 27 years ago, Wilbrand invented the production method of TNT, but the real industrial production, but the next year, the German chemist Hausermann innovated the production method, the invention of the three-stage nitrification method, the industrial production of this single explosive became a reality, but it was not until ten years later, it was adopted by the German army.

"Generally speaking, the process of producing TNT is like this, it is not complicated, of course, its production requires a large amount of concentrated sulfuric acid, concentrated nitric acid, and toluene, which can be exported for the time being, well, and then set up a factory to produce it when the time is ripe in the future......"

Thinking of explosives, Tang Haoran thought of more than a dozen kinds of European fertilizer powder in the Nanbie Palace, which was specially commissioned to import "fertilizer powder" in order to increase the "yield", which is actually chemical fertilizer, and among them is the German production of "ammonium nitrate", which is not only a chemical fertilizer in later generations, but also an important military and civilian Z medicine, and now its price is not even higher than black medicine, if ammonium nitrate is used as Z medicine, its power may be inferior to TNT, but it is far stronger than black powder.

In his thoughts, as Zheng Tingxiang motioned to the workers to set up a steel pipe, Tang Haoran hurriedly put aside the thoughts in his heart and walked to the steel pipe with the bracket.

"Mortars made?"

Mortar?

Shang Dequan, Wu Dingyuan and others, who walked to the steel pipe with the adults, looked at the steel pipe as thick as a fist in surprise, their eyes were full of incomprehension, and there seemed to be too many surprises waiting for them on this shooting range today.

"My lord, this cannon tube is the steam pipe of the ship's boiler, and other things are extremely simple, but this steel pipe is difficult to make, and there is no equipment in the factory to process it, so I took it upon myself to buy twenty 3.2-inch steam pipes from Shanghai, and it is just right to use, one steel pipe can be cut into four 50-inch gun tubes, and as for the cannonball fire, it is caused by a No. 12 shotgun ......bullet."

In addition to the explanation, Zheng Tingxiang's face looked a little proud, he did have a reason to be proud, although the mortar and grenades, bridge clips, etc. were designed by Tang Haoran, but they were perfected by him, especially in the design of the mortar, he fully demonstrated his talent as a mechanical engineer, from the tripod, to the design of the universal joint, to the design of the shell and the selection of materials.

"Let's take a look at the big guy with two shots first!"

Looking at the mortar, Tang Haoran just smiled and nodded, talking about the equipment and machine factory is not necessarily much worse than the equipment in the base area during the Anti-Japanese War, at least the variety is complete, such as steam hammer and other equipment, which is not available in the base arsenal, as long as he gives a little prompt, it is not surprising that the factory can make "epoch-making" weapons such as grenades and mortars.

The four mortars are lined up in the "artillery range", which is the shooting range of the "Salute Team" directly under the Ministry of Police to train and operate the Krupp camp guns, of course, the "Salute" is only the external title, internally, it is the only artillery under the Ministry of Police.

In the eyes of everyone, the gunners in the factory tied the gunpowder packets with wire to the tail fin, each cannon prepared ten shells, six pounds of shells were placed on the ground, four gunners for each cannon, and even Zheng Tingxiang himself acted as gunners, looking at this scene, Tang Haoran's lips raised, and he instantly understood Zheng Tingxiang's thoughts, he wanted to shock everyone.

Tang Haoran, who had witnessed the shooting training of the "salute team," had witnessed the "rapid fire" of one or two rounds, but if compared with the rapid fire of mortars, it was simply a race between a lame man and Bolt.

In anticipation, Zheng Tingxiang's voice suddenly burst out a few words.

"Ready...... Put! ”

In the next moment, the loader immediately picked up the shell, stood on the muzzle of the cannon, loaded the cannonball into the chamber, and picked up another cannonball while bending down to avoid the impact of the muzzle.

"Tom, tom......"

It was not deafening, and even a little dull cannon sound, the shells shot out one after another, but a few seconds later, everyone was attracted by the explosion and smoke thousands of kilometers away, and the shells exploded one after another, and in just more than 20 seconds, ten shells were exhausted, and the end of the shooting range was completely shrouded in gunsmoke.

The four mortars fired dozens of cannon firepower, only Shang Dequan and Wu Dingyuan, the two police chiefs who had studied artillery in Germany, all looked at the scene in front of them in a daze, if they hadn't seen it with their own eyes, the two would have thought it was a joke, but now, they were completely stunned by the firepower displayed by the mortars.

"This, how is this possible! Hit so fast! (To be continued......)
