When Shen Mo came to the Southern Song Dynasty, his army was quickly established and suddenly became a strong army.

These are actually all the experiences learned in an underground military factory when Shen Mo was undercover in his previous life.

So at the beginning, Shen Mo's knowledge in metal smelting and processing enabled him to quickly make his weapon production reach a certain level.

After that, due to the serious lack of knowledge in electrical and chemistry, Shen Mo also made his arms industry more and more difficult to move forward.

So what Shen Mo has to do now is not to hastily research any new weapon.

Instead, we must improve our overall industrial level bit by bit.

Start with a pressure meter, start with a thermometer that can be more accurate, and start with a thousandth of chemical purification.

Shen Mo is trying his best to improve his background and slowly consolidate the basic part of the industry.

Now Shen Mo has realized that only by a deep accumulation can the power of modern industry be exuded.

However, although Shen Mo's approach was positive and steady, he followed the right path of industrial development.

However, the current lack of medium-range firearms in his army is an indisputable fact.

...When An Jun learned about Shen Mo's worries, the young master quickly checked all the information on Shen Mo's hand.

As a disciple of Shen Mo, An Jun has a very high level of confidentiality in industry.

So he saw even the drawings of Shen Mo listed as top secret mortars and shells with his own eyes.

After that, an idea suddenly came to An Jun's mind.

In fact, the problem of large overload that the mortar shell fuze needs to solve is to prevent the firing needle in front of the fuze from moving backward due to recoil when the shell is out of the bore, causing firing.

But it was this problem that the military industry department had to overcome so hard that An Jun found a way out and thought of another solution.

What An Jun thought of was: Since the cannon was overloaded, what else should I do to overcome it?

It’s better to just use this overload to let the needle on the shell directly fire the fuse! After the fuse is fired, just add a delayed gunpowder column for four or five seconds behind the fuse, and then ignite the charge inside the shell?

So, An Jun quickly designed a weapon according to this reverse idea.

After he tested the shooting, he found that it was completely available for use by the troops.

After that, An Jun kept modifying his design, in addition to making the design of this weapon more and more perfect.

We also try our best to make it lighter and smaller, and the mechanism is simpler and easier to produce.

And An Jun also put a lot of effort into the safety of the shells.

Because this kind of shell is actually completely different from mortar shells.

Mortar shells will only cause an explosion when they touch the ground at the enemy's feet, and this shell will start to time when they exit the barrel.

After the shells flew for four or five seconds, they would explode immediately no matter where they flew.

So even the designer An Jun himself couldn't understand what the name of this infantry light weapon was.

...Then, after An Jun handed over all the design drawings, trial weapon samples, and experimental reports to Shen Mo.

When Shen Mo saw the thing on the drawing, he suddenly let out a long sigh! He had seen this thing! Shen Mo was thinking about the mortar and actually forgot this thing! And An Jun was so smart that he "redesigned" this weapon in history! Even the weapon made by An Jun was very similar to that in history, and the principles were basically the same.

The reason why Shen Mo forgot about it before was that it was only equipped in a limited army of one or two countries, and it was also a flash in history.

However, this thing is definitely usable, and it just fits the current battlefield requirements!... This kind of weapon is the "grenade tube" that can be seen frequently on the Anti-Japanese battlefield.

This weapon, also known as "light mortar", was equipped in the Japanese invading China.

Because it is extremely small and light, it does not even occupy a system, and its shooting distance is far beyond the distance thrown by grenades, it played a very important role in the Japanese army's war.

During the Anti-Japanese War, soldiers from our army often said that as soon as the machine gun on their side fired, the grenade launcher would come immediately.

This shows how small and lightweight this weapon is, to how flexible it is to use.

The length of the barrel of this grenade can be less than 30 cm and the diameter is less than 50 mm.

It looks a bit like a piece of sugar cane that is one foot long, with a handle as thick as a finger and as long as a chopstick.

The end of the handle is accompanied by a pallet the size of a playing card...of course it is all made of steel.

In addition to standard shells, the Japanese army could even use it directly to fire the Type 91 grenade.

During that war, even other domestic armed forces and our army imitated this grenade launcher, especially the products of the Huangyadong Arsenal, which were used by our army to cause a large amount of damage to the invaders.

Take the Taisho Tenth Grenade Bullett as an example. Its caliber is 50 mm, its weight is only 2.\n6 kilograms, and its range is 175 meters. All indicators are very consistent with Shen Mo's requirements for infantry weapons.

Anyway, for him, as long as he can exceed the range of the Mongolian army's feather arrows.

At a distance that the opponent cannot reach, it is enough to blow them up! So Shen Mo immediately decided to continue to improve the design and production technology of this weapon, making it safer and more reliable and more combat performance.

Now this new grenade launcher has begun trial production and experiments in Shen Mo's military factory, and it should be able to equip the troops on a small scale soon.

An Jun, the hero who designed this grenade launcher, was awarded a gold pineapple sword medal by Shen Mo for this great achievement.

...After this young master An Jun became a disciple, his learning speed has improved by leaps and bounds due to his talent in machinery.

Moreover, the psychological problems of this half-aged child were gradually reversed under Shen Mo's attention.

Before this, An Jun suffered psychological trauma in his childhood, so his personality was distorted, taciturn, and it was difficult to deal with others.

Shen Mo knew very well that childhood injury and psychological distortion, if he was extremely smart, he would almost be a model for a murderer when he grew up.

Therefore, when Shen Mo was treating psychological problems of Zheng Anjun, he really did everything he could do.
