Gunpowder is the most fundamental thing of all gunpowder weapons, and without it, the new muskets and bombs that make the eyes of the envy of all human nations turn red at once and are no better than burning sticks and stones.

With picric acid, it also means that a series of weapons of the Iron Collar finally have the cornerstone of upgrading.

As if having found the best and most curious toy, Modo and the Brood both stopped their research and began to design new weapons with great interest.

The little dwarf Modo is better, no matter what, he is the main energy, devoting himself to the cultivation of internal strength, only when he needs to relax, he starts to design new weapons;

When these design drawings were shown to the little dwarf with the mother's mind, Moduo led the mother's nest and didn't know how many years of experience in the use of gunpowder weapons, I had to exclaim: these nearly 100 kinds of weapons, special! Not a single one is of some use.

In the end, after being hit repeatedly, the brood accepted this cruel reality, at least with his current ability to innovate, he was really not suitable for the development of this job, and he was most suitable for the current situation, or to do some work to assist the little dwarf.

With the dedicated cooperation of the brood, the first results soon appeared; for the bomb No. 1 currently in use, the iron ball bomb is clumsy, and the power can only be said to be barely passable, so Moduo first improved the bomb, and at once he took out two models, which were called bomb No. 2 and bomb No. 3 respectively.

Bomb No. 2 was mainly used by infantrymen, and its appearance was completely an enlarged version of the rabbit's wooden-handled grenade in his previous life; Modo, who was sixteen years old in his previous life, did not know how many times he had blown up fish with this kind of thing, and was very familiar with the structure inside.

The reason why Bomb 2 is made so big is mainly because the physical fitness of the orcs in this world is several times stronger than that of ordinary people in the previous life.

After magnifying it several times, because of several times the charge, the power of Bomb No. 2 is also amazing, and Modo estimates that even if it is a heavy armored cavalry with amazing defense, after this thing is smashed and exploded, it can be put down.

As for Bomb III, it was completely designed for the bombing tactics of the Harpys, and the appearance was still a replica of the previous life.

In the old war movies of the previous life, there are often scenes of a series of bombs sliding down after an airplane opens the hatch, and Modo copied the style, of course, the weight and specifications have been reduced a lot, otherwise those eagles will not be able to carry that thing even if they are exhausted.

Both Bomb 2 and Bomb 3 not only used a new type of picric acid gunpowder, but also a breakthrough technology.

It was the method of ignition that allowed the poor grenadiers and harpies to throw bombs without having to pay attention to the torches in their hands, or whether the rope had been blown out......

The little dwarf, who had succeeded in improving the bomb, was immediately in high spirits, and then he wanted to improve the musket as well, and his plan was to improve the current backward front-loading smoothbore gun at least into a rear-loading rifled gun;

Unfortunately, the cruel reality told him that he was too naïve to think about it until he solved a dozen key problems, and that the manufacture of copper-shelled bullets alone was a bunch of problems in front of him.

After tinkering back and forth for half a month, the little dwarf Master Modo had to give up this unrealistic idea, and in the end, he only modified the previous musket slightly, and continued to digest the batch of information of the untrustworthy.

However, it was Master Modo, who was extremely dissatisfied with this improved musket in his heart, and after it fell into the hands of the soldiers of the Iron Collar Field Army for the first time, those musketeers immediately fell in love with this powerful weapon.

First of all, in order to adapt to the wild power of picric acid gunpowder, the improved musket all used a new barrel, the material of this barrel is a high-quality alloy researched by the mother nest, which is very strong and durable, and the life of each qualified barrel is more than 10,000 shots.

Secondly, in order to change the embarrassing situation of the previous old musket, which was difficult to aim at a distance of fifty paces and completely lost its accuracy at a distance of a hundred paces, the new barrel was all drawn out of rifling inside.

The improved musket is now capable of easily breaking through the opponent's heavy armor in two hundred steps, and the longest range is four hundred paces, and after the opponent has entered two hundred steps, a skilled gunner can have nearly half of the hit rate, which was unimaginable before.

Finally, the tip of the barrel of the musket had more than a dozen threads on the surface, which allowed the characteristic bayonet to be mounted on the front end of the musket.

Although a musket equipped with a bayonet cannot continue to fire, it can immediately turn into a spear, forming a musketeer formation, and in the face of hand-to-hand opponents and even cavalry onslaught, it will not be like before, without any means of resistance, like a lamb to the slaughter......

The little dwarf Master Modo, after two years of retreat and cultivation, finally encountered the legendary bottleneck.

After two years of hard cultivation, and with the help of those pure energies remaining in his body, he had already stored all the meridians in his body with viscous liquid-like internal qi, and now he had reached the point where no matter how much he cultivated, he couldn't store more internal qi.

The problem is that the little dwarf feels that he is getting closer and closer to the realm of the super strong, and even the gap between entering the realm of the super strong may only be as thin as a piece of window paper, but how to pierce this window paper has become the biggest obstacle for the little dwarf at present.

In addition, the pure energy in the body, after two consecutive years of cultivation, has also been completely consumed, and now everything depends on the little dwarf himself.

When he first stepped into the innate realm, Mo Duo remembered that the internal qi in his body had changed from the initial airflow form to the liquid form now, so if he wanted to make the internal qi go further, how should he change it, and it would not directly become solid!

Thinking of this, the little dwarf Modo felt inexplicably amused at his genius idea, if he really wants to become a solid state, how should the internal qi run in the body?

And that thing that is solid in the body, isn't it more appropriate to call it a meridian stone?
