Now it's a new kind of teaching, and everyone can accept simplified Chinese from the beginning.

Such efficiency is undoubtedly the highest. It also saves time for Lu Bu to write more advanced courses in the future.

In addition to the simplified Han Li's double edition of the Book of Poetry, Analects and other books, Lu Bu also personally compiled enlightenment readings such as the Three Character Classic, the Hundred Family Names, the Thousand Character Text, and the Rhyme of the Liweng.

There's no way, a scholar like Lu Bu has actually been forcibly cultivated since he was an infant.

Although some of them are incomplete, Lu Bu still remembers them all. For example, some of the contents of the three-character classic have not yet been published and need to be deleted.

And these famous enlightenment books have not yet been born in this era.

In order to conform to the current world, Lu Bu also decided to publish Cai Yong's "Persuasion of Learning" as well.

This also had a political purpose, as proof that Lü Bu did not reject contemporary Confucianism.

However, in order to implement simplified characters, Lu Bu had to write the most formal italics. In this way, the worker can still engrave the mold and facilitate printing. Therefore, the speed of writing books in the early stage is naturally extremely slow.

Fortunately, Lu Bu is now living a stable life and has a lot of time to write books.

However, before he had been stable for half a month, Sun Guan came with news.

Yuan Shu raised troops in Beihai with the intention of attacking Langya.

Hearing this news, how could Lu Bu not be surprised.

He didn't expect Yuan Shu to raise troops so quickly.

With his understanding, shouldn't Yuan Shu be obscure, develop his power well, and then give him a fatal blow at a critical moment.

With Yuan Shu's current strength, what can he do to fight him and find death.

But Yuan Shu's actions made him smell the breath of war.

In this way, Lu Bu had to suspend writing books and run to the arsenal in person.

He had previously designed a lot of heavy equipment, and he wanted to see how his research went.

And the first instrument that Lu Bu asked people to focus on was the three-bow bed crossbow.

Because this thing is not only a weapon for defending the city, but also not weak for siege. In the era of cold weapons, its power is second only to that of a stone thrower.

The three-bow bed crossbow, also known as the octagonal crossbow, is a masterpiece of the Song Dynasty. Three bows in one, it takes 30 people to pull it apart. Able to shoot a thousand steps, in ancient times, one step on each of the left and right feet was called a step, that is, each step was about 1.5 meters. 1,000 steps is 1,500 meters.

Such a range is a miracle.

And more importantly, it is extremely powerful, which can even wear people with armor a few times back and forth!

Now that the saltpeter mine has not been found, it is impossible to vigorously develop thermal weapons, and Lu Bu has to study cold weapons first.

The three-bow crossbow can also be used for sieges, where arrows are fired directly into the walls of the city walls, and soldiers can then climb them.

Lu Bu is also a military fan, not only has a deep understanding of modern ordnance, but also has a lot of knowledge of ancient equipment.

The structure of the three-bow bed crossbow has long been handed over to the arsenal for development.

When Lu Bu saw the three-bow bed crossbow developed by the arsenal, he couldn't help but smile and nodded.

Basically, it was built according to his imagination, with pulleys tuning the strings and gears driving the rolling bearings to pull the strings.

In this way, two or three people are enough to operate such a heavy machine.

In addition, each part can be easily disassembled, making it easy to transport and assemble. Now the craftsmen of the arsenal have become accustomed to using fasteners such as screws.

"How's it powering?" Lu Bu asked.

Lu Bu has always been extremely demanding, and the steward was frightened, and said weakly: "Back to the temperature, the current range can only reach eight hundred steps, and there is still a lot of distance from the thousand steps required by the lord." It's ...... for me."

It turned out to be only eight hundred steps, and Lu Bu frowned.

When the people saw this, they were terrified.

"Do you know why?" Lu Bu didn't want to blame too much, but wanted to find the cause and find a solution.

"The main thing is the toughness of the bowstring. If you blindly pursue range, not only will the service life be greatly reduced, but also extremely dangerous! The steward was terrified, for someone had been seriously injured before.

Lu Bu nodded and asked, "If you make it with all your might, how much can you make?" ”

The management thought for a moment: "According to the inventory, up to a hundred vehicles." ”

"A hundred?" Lu Bu couldn't help but cheer.

This amount is simply outrageously low.

But he was also quick to figure out why, because of the lack of bowstring material.

The bowstrings of this era were basically made of beef tendons.

And where does the cow tendon come from, it naturally comes from the cow.

You must know that the animal power of this era mainly depends on cattle.

In the past ten years since the outbreak of the war, the number of cattle in various places has simply decreased sharply.

Without protection, it will be difficult for the people to cultivate their land.

Lu Bu will not do anything to quench his thirst, and he will not kill ploughing cattle on a large scale.

In this way, Lu Bu could only nod and let people build 100 of these three-bow bed crossbows first.

Lu Bu didn't think about making a modern composite bowstring, but this material was not something he could study at once.

Before there was no better choice, Lu Bu only made one request for craftsmen.

That is, accuracy must be required, the range can be ignored for the time being, and the accuracy must be achieved.

In this way, the 100-bed crossbow may be able to do some wonders.

You must know that in history, this kind of three-bow bed crossbow was used to behead the enemy's main general, and he obtained miraculous feats.

If there is any military resource that is the most important under Lu Bu's rule, it is steel.

Its number cannot be compared with any candidate, because Lu Bu has a better smelting process.

In fact, Lu Bu wants aluminum alloy materials the most, but unfortunately he can't reach the sky in one step.

Without electricity, there is no electrolysis of aluminum at all. Although aluminum ore was discovered, Lu Bu could only look at aluminum and sigh.

Therefore, most of the soldiers and horses under Lu Bu's command now have heavy armor. Fighting in the wild, not afraid of anyone at all.

The only flaw is that the heavy armor is too heavy to fight for a long time.

And Lu Bu's steel Tang Mo knife can be described as a supreme artifact. Weapons made of ordinary pig iron are completely cut off.

Lu Bu went to the arsenal every day to learn about the production of various weapons.

Something like a stone thrower, although Lu Bu also asked someone to develop it, but it did not let people mass produce it.

Because he didn't think about attacking the city, he just wanted to defend it first.

According to his thoughts, it was after he developed a hot weapon that he chose to attack.

So trebuchets, perhaps, will not be born at all.

Since Lu Bu's most resources were steel, Lu Bu quickly thought of two sharp weapons for defending the city.

Mace and mace.

The wolf's tooth slap is to nail iron nails to wooden planks and then hoist them at the head of the city with a winch.

If an enemy wants to climb the ladder, they can use it as a hood.

And the mace is also very well understood, it is a mace with iron nails.

Then use the pendant to drive the mace to shake, so that how many people come and how many people die.

You must know that although this is a cold weapon, it is also an epoch-making product.

And in the Three Kingdoms period, there was none. It was during the Song Dynasty that it flourished in the world.

It has to be said that although the Song Dynasty was weak, it also created many epoch-making military equipment. You must know that even the epoch-making product of artillery was created during the Song Dynasty.

Lu Bu quickly explained this, and wanted to arm the cities as soon as possible.

And the current focus is naturally on Langya and Mount Tai.

Three days later, after hearing that Yuan Shu had indeed raised troops, Lu Bu also personally brought 5 three-bow bed crossbows, 20 wolf tooth paddles, and 30 maces to Langya.

No, Lu Bu just wanted to witness the power of the new weapon with his own eyes.
