Time: November 16, the first year of Maude.

Location: Da Song Guozijian, the backyard of a temporary production base of the Ministry of Industry.

Hu Biao picked up a new type of grenade, twisted the lid at the bottom of the wooden handle, took out the pull cord from it, and put it on the index finger of his left hand.

Seeing that the wolf nodded to himself, he said, "You put ten thousand hearts to pull the fire."

Finally, the index finger of his left hand pulled the rope hard, and his right hand picked it up and threw it out about 212 meters.

The whole process is not like before, and you have to hold incense sticks and torches to light the fire.

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

The flying fragments of cast iron put some scarecrows on some of the targets with some armor, and the 'clanging~' of the impact kept rattling.

Yes! Today, the way to pull grenades and explosives bags has finally been improved by Wolf Qing.

Then I notified Hu Biao to come over and test it to see if it was good or not.

If possible, then it is necessary to improve all the previous inventory in addition to unleashing production.

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

Then some copper wire was rolled into a ball and placed in glass powder.

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

Therefore, as long as the spark generated by the friction between the copper wire and the glass powder is easily pulled, the fuse and sulfur can be ignited, and finally the effect of triggering the explosion of black powder can be achieved.

Whether it's a grenade or a more powerful explosive pack, it's the same principle of pulling hair.

Seeing that the first grenade was successfully pulled, Hu Biao threw out all the ten grenades processed by Wolf Qing in one breath in the following time.

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

With a smile on his face, he made an evaluation in his mouth:

"Wolf Qing, this self-pulling grenade is really much more convenient; The only problem is that it takes too long to be detonated after each sound.

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

In such a long time, enough for the other party to pick it up, and then throw it back to our side.

So you see if you can adjust it and make it explode in three seconds at most; In short, no matter whether it can be adjusted or not, it will be fully produced after two days, and how much can be made.

Because even if the detonation takes a long time, it doesn't seem to be a big deal, it's amazing, just hold it in your hand and count three counts, and then throw it out. ”

Facing Hu Biao's question, Wolf Qing answered dryly.

"Detonate in three seconds, right, no problem, I'll be able to change it well tonight by working overtime."

At this point, there is a matter of hair pulling device, even if it is completely finalized; The principle of dynamite bag pulling is the same, and there is no need to continue the test without bothering.

It's just that Hu Biao came here this time, not just for such a trivial matter as pulling the hair device.

Besides, if Wolf Qing had been busy for so many days, if he had only tossed such a trivial matter, then his 'eighth-level fitter' skill book would be used in vain.

In fact, the so-called hair pulling device is only an appetizer, and the real big dish is still in the back.

So in the following time, Wolf Qing and Hu Biao finally came to today's trip to the Ministry of Industry, in front of a real 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 uses the black technology that is as epoch-making as it was during the Northern Song Dynasty.

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

However, the mere use of ball bearings has improved the technology of almost 800 years.

You know, it was not until 1881 that ball bearings were invented in the Netherlands and were still used in ice skating.

On the wheels, after using ball bearings, it can not only increase the life of the wheels, but also increase the speed and load capacity.

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

Therefore, in addition to the consumption of weapons and equipment, there is a surplus of at least eleven or twelve tons per day; In this way, in some key parts of the frame, components made of 100 steels are also used.

Even on the frame, some elastic yellow steel was used.

Therefore, under such a modification, in the case of immediately letting the same two mules pull the cart, this new type of cart will at least double the loading capacity.

If you take into account the improved efficiency and traffic capacity, I am afraid that the increased carrying capacity will be more than five times, or even more.

This can play a key role in the Northern Expedition of the Great Song Dynasty.

After all, after a rough estimate, in the operation of this Northern Expedition, the new army under their own command was counted, as well as the troops and people sent to help from all over the country.

In terms of total troops, it will exceed 300,000 people.

Boy! On this day, the amount of grain and grass that people eat and chew will be astronomical.

Although as long as the land and water are advanced, some sailors and civilian fleets can be passed, and the logistics materials needed can be transported with relatively higher efficiency.

But there are still many places where a lot of war materials still need to be transported by large trucks.

Second, these carts are used to transport supplies, which is only for one purpose; In addition to these, there are some great military aspects.

For the new army of the Great Song Dynasty, the greatest threat was always the cavalry of the Jin people.

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

Whoever called their two cavalry divisions, by now although the number has been full.

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

It is simply unrealistic to rely on this mere 20,000 cavalry to fight against the cavalry of the Jin people with an astonishing number and stronger quality.

But with these big cars, everything is different.

In the following time, Wolf Qing and the three craftsmen were busy.

In a short period of time, the four of them used some wooden planks and timber wrapped in iron sheets to turn the original open-top cart into a sturdy van.

On the outermost plank, there is a large hole and several small holes, which at first glance look like a small Fran cannon, and a musket for firing.

Suddenly, in Hu Biao's braincase, such a picture appeared.

As soon as it was in the process of marching, it was released to wander around at night without receiving, and the movement of the enemy's cavalry was discovered, and the signal was immediately issued.

Then the convoy in the marching procession immediately formed an oversized circle.

Leaning against the wall-like wooden walls, they can not only defend against the cavalry of the Jinren, but also use muskets and artillery to consume the strength of their opponents.

After those golden cavalry and continuous attacks fell, the cavalry in the large array could be killed in one go.

The whole process can only be done with stockings, no! It should be described as silky.

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

If there are any difficulties, just mention it, and I will support you by smashing the pot and selling iron. ”

After hearing this, Wolf Qing shouted disdainfully: "No need, keep your pot."

The concubine's commercial department only reminded the franchisees that we needed carpenters and lumber, which had been shipped in a steady stream from all over the world lately. ”

Although he was scolded by Wolf Qing, after Hu Biao heard it in his ears, he didn't feel unhappy at all.

That is when he finally felt the pleasure of 'transporting heaven and earth together' in the various unsmooth tasks that the system has always had......
