Start: Datang Wanli a lonely city

Chapter 515

Time: November [-]th, the first year of Maode.

Location: Dasong Guozijian, the backyard of the temporary production base of the Ministry of Industry.

Hu Biao picked up a new-style grenade, unscrewed the cover at the bottom of the wooden handle, took out the drawstring, and put it on the index finger of his left hand.

After seeing Lang Qing nodding to himself, saying 'You put 1 hearts on fire'.

Finally, it was the index finger of the left hand, which pulled the rope vigorously, swung the right hand and threw the thing about 21 meters away.

The whole process is not the same as in the past, and it takes a lot of effort to light the fire with incense sticks and torches.

But just like that, the grenade exploded violently shortly after it hit the ground.

The cast iron fragments splashed, and some scarecrows were put on some armored targets, which was called a 'jingle~' of the impact, making a continuous sound.

Yes, that's right!Today, Langqing took the time to improve the way of pulling grenades and explosives.

Then I notified Hu Biao to come and test it out to see if it works.

If it is possible, then we have to let go of production and improve all the previous inventory.

In fact, to put it bluntly, this hair pulling method is quite simple in principle: it is to put some glass powder in a small steel pipe.

Then roll some copper wire into a ball and put it in the glass powder.

One end of the copper wire is connected to the pull rope, and the other end is connected to the fuse and sulfur.

Therefore, as long as you pull it easily, the spark generated by the friction between the copper wire and the glass powder can ignite the fuse and sulfur, and finally achieve the effect of triggering the black powder explosion.

Whether it is a grenade or a more powerful explosive package, it is the same pulling principle.

Seeing that the first grenade was successfully fired, Hu Biao threw out all ten grenades processed by Langqing in one go.

After seeing every grenade with my own eyes, without exception, it was successfully detonated.

There is a smile on the face, and an evaluation is made in the mouth:
"Langqing, this automatic grenade is really more convenient; the only problem is that it takes too long to detonate after each one is fired.

I just counted silently, and it took seven seconds for this thing to explode.

In such a long time, it was enough for the other party to pick it up and throw it back to us again.

So see if you can adjust it so that it explodes immediately in a maximum of three seconds; in short, no matter whether you can adjust it well, it will be fully produced after two days, as much as it can be produced.

Because even if the detonation time is longer, it doesn't seem to be a big deal, just hold it in your hand and count to three, and then throw it outside. "

Facing Hu Biao's question, Lang Qing answered simply.

"It will detonate in three seconds, no problem, I can fix it by working overtime tonight."

At this point, even if the matter about the pulling device is completely finalized; the principle of pulling the explosive pack is the same, and there is no need to continue the test at all.

It's just that Hu Biao's trip here is not just for such a trivial matter as pulling the hair device.

Besides, if Lang Qing has been busy for so many days, if such a trivial matter happened, then his skill book of 'eighth-level fitter' can be regarded as useless.

In fact, the so-called hair pulling device is just an appetizer, and the real big dish is still behind.

So in the following time, Lang Qing and Hu Biao finally came to the trip to the Ministry of Industry today, in front of the real big dish; more precisely, it was a special big car...

*****
The reason why such a big car is very special is that the big car in front of me used the same black technology as epoch-making during the Northern Song Dynasty.

First of all, in terms of wheels, although wooden wheels are still used, there is no such thing as rubber tires.

But just using ball bearings is almost 800 years of technology improvement.

You know, the original historical line needs to be in 1881, the ball bearing was invented in the Netherlands, and it was still used in skating.

As for the wheels, the use of ball bearings not only increases the life of the wheels, but also significantly increases the speed and load capacity.

In addition, because the steel output in Kaifeng City has reached 31 tons per day.

Therefore, in addition to the consumption of weapons and equipment, there is still a surplus of at least eleven or two tons per day; in this way, some key parts of the frame are also made of steel-making components.

Even on the frame, some spring steel is used.

Therefore, under such a modification, when the same two mules are immediately used to pull the cart, the loading capacity of this new type of cart is at least doubled.

If the improved efficiency and traffic capacity are included, the improved carrying capacity may be more than five times, or even more.

This can play a key role in Song Dynasty's Northern Expedition.

After all, after a rough estimate, this time the Northern Expedition included the new army under their own command, as well as the troops sent to help from various places, such as civilian husbands.

In terms of total strength, there will be more than 30 people.

Good guy!In this day, the amount of food and grass chewed by people and horses will be an astronomical figure.

Although as long as the land and water advance together, some naval and private fleets can pass through, and the efficiency is relatively higher to deliver all the required logistics materials.

But there are still many places, and a large number of combat materials still need a large truck to be transported.

Secondly, the use of these carts to transport materials is only for one purpose; in addition to these, there are also some great military functions.

For the new army of the Song Dynasty, the biggest threat will always be the cavalry of the Jin people.

Especially in the northern plains, once encountering an opponent's cavalry raid during the march, it will be the most troublesome problem.

Who called their two cavalry divisions, although the number has been fully recruited by now.

But many of the knights are now barely able to ride on horseback without being thrown off.

It is simply unrealistic to rely on this mere [-] cavalry to fight against the golden cavalry with an astonishing number and stronger quality.

But with these big cars, everything is different.

In the following time, Lang Qing led the three craftsmen to get busy.
In a short time, the four of them used some wooden boards and wood wrapped in iron sheets to turn the cart that was originally an open top into a sturdy van.

On the outermost wooden board, there is still a large hole and many small holes. At first glance, it looks like a small Franco cannon and a musket for firing.

Immediately, such a picture appeared in Hu Biao's head.

Once it was in the process of marching, it was released to cruise around at night, and when it found the movement of enemy cavalry attacking, it immediately sent a signal.

Then the convoy in the marching team immediately formed an oversized circular formation.

Relying on the wooden wall like a city wall, they can not only defend against the golden man's cavalry and shooting, but also use muskets and artillery to consume a lot of opponent's strength.

After those golden cavalrymen's continuous offensive momentum subsides, the cavalrymen in the large formation will be able to fight out in one go.

During the whole process, only stockings can be used, no!It should be described as silky smooth.

In the end, Hu Biao said to Lang Qing with great satisfaction: "Very well, as long as enough carts are produced before February next year, your Ministry of Industry will be the first to make a contribution in this Northern Expedition.

If you have any difficulties, just mention them, and I will support you here. "

After hearing the words, Lang Qing yelled disdainfully: "No need, keep your pot.

The business department of the imperial concubine just mentioned to those franchisees that we need carpenters and timber, which have been continuously shipped from all over the world recently. "

Although he was stunned by Lang Qing, after Hu Biao heard it in his ears, he didn't feel uncomfortable at all.

That's when he finally felt the joyful feeling of 'the heaven and the earth all work together' in all kinds of unsatisfactory tasks in the system all along...
