It is undeniable that Chongzhen is a simple emperor, and he can reduce his expenses to eat vegetables and wear patched imperial robes for the military salary of the border soldiers.

He is also a diligent emperor, and even his disease of disgrace is inseparable from his perennial stay up late and lamenting all nights.

Coming out of the palace, Liu Hongjian was still reminiscing about Uncle Chongzhen's words.

Swinging down and not being a minister, and the people are safe, is Chongzhen's requirement for himself, and it is also an explanation of the ancestors' foundation.

Alas, it seems that this person, no matter what difficulties he encounters, should still be more open-minded and open-minded.

After all, a sad face every day is not beneficial to solving the problem.

When he was in Shanhaiguan, although the soldiers there lived very hard, and even did not have enough food and clothing, Liu Hong gradually never saw these people with sad faces.

Not only that, but these Liaodong men also like to make some meat jokes, and a meal of meat is enough to make them happy for several days.

Liu Hong gradually discovered that the poorer the place, the more open-minded the people there lived.

Because if a suffering person is pessimistic, he will not have the courage to face the reality, nor will he have the strength to fight against difficulties.

Uncle Chongzhen is definitely not among them, and among the more than a dozen emperors of the Ming Dynasty, except for the father and son who founded the country, the rest are all emperors who keep the success.

In addition to Taizu and Chengzu, the only two who have been on the battlefield and have recorded one is Wuzong Zhu Houzhao, who is said to have killed the Tartars with his own hands.

The other is Yingzong Zhu Qizhen, which directly created the change of Tumubao that is comparable to the shame of Jingkang.

In addition to the two founding ancestors and these two unfortunate two poles, the emperors of the Ming Dynasty almost rarely even went out of the imperial city, and Chongzhen was even more so.

In general, it is a lack of exercise, sitting every day without exercise, and staying up late, and staying up for 18 years......

I can't stand this special iron man!

Alas, it seems that this Zhu Cihong also needs to be trained and trained, otherwise according to the temperament of this stupid boy, it is definitely a copy of his father.

On the way home from the palace, Liu Hong gradually thought a lot.

Too many things have happened in the past year, he has a father, has two wives, and is about to become a father again.

He enjoys the glory of the envy of others, and bears the safety of the border pass, he can go to the court to fight the keyboard warrior, or he can carry the AK Tutu Tunguska boar skin.

The hungry homeless and the robes that died in battle made him quietly change his concept of being at peace with what he encountered, and he was no longer the one who only wanted to be a small landlord and hug his daughter-in-law.

The attachment of his family and the expectations of the saints made him understand that there is no high authority and light responsibility, and even if there is, it will not last long.

When he arrived at home, even Sun Xiuxiu, who was about to give birth, asked many times, but at this time, Liu Hongjian already knew what he was going to do, and naturally he would not tell them about these things.

But who knew that the buttocks were not hot at home, so a few soldiers from the Thousand Households came on horseback, saying that Song Yingxing heard that he came from the border and invited him to the ordnance station.

The armory was almost next to the camp of the Thousand Households, and among the soldiers who had come from Dengzhou Mansion on horseback with him before, except for dozens of people in the capital, the rest lived directly in the barracks.

Liu Hong gradually didn't know what was going on in the ordnance institute, according to the past, with the calm personality of Song Yingxing, the head of the second gear, plus his courage to delegate power, the basic ordnance institute was the most successful for him.

Under Yang Xue's Zhang Luo, Liu Hong, the chef of the Hou Mansion, had just put the prepared meal on the table, and Liu Hong had already gone out.

galloped all the way, and before he arrived at the armory, he faintly heard a loud banging sound in the direction of the armory.

It was not like the sound of a gun fired or like an artillery, but it was somewhere in between.

This made Liu Hong even more confused.

"Hello Hou Ye! Hou Ye is here! The soldiers stationed at the armory station saluted Liu Hong, and another soldier took his horse and shouted inside.

"My lord, Song thought that the adult was still at the border!

Hearing that the military master of the Qianhu Institute said that you are back, Tang Tu invited the Hou Ye here because Song had something important to report. ”

I haven't seen Song Yingxing for a month, but he is in good spirits, and I heard that his youngest son added a grandson to him last month.

Now that there are such good facilities for scientific research, Song Yingxing doesn't mention how happy he is.

"This is not Song Lao's style of acting, why did you call Ben Hou over? Could it be that the cannon came out? Liu Hong gradually guessed.

When he set out to build a captivity a month ago, Liu Hongjian handed over the original version of the canon paper and grenade drawings in the "Encyclopedia of Military Weapons" to Song Yingxing.

Even the illustration of the open-hearth steelmaking method was given to him.

In fact, this cannon has been in use by Europeans more than 100 years ago.

Around the time of the Renaissance, Europeans began to make explosive breakthroughs in physics, chemistry, and applied mathematics.

Piles of masters of astronomy, physics, chemistry, and mathematics appeared, which provided a substantial theoretical basis for the improvement of weapons and armaments, and it was for this reason that the West began to rapidly overtake the East in all aspects.

The improvement of the cannon was also continuous, and in 1453 AD, the wall of Constantinople, which had stood for thousands of years, also collapsed under the cannon fire.

In fact, the emergence and development of the cannon forced the redesign of some of the fortifications, which also gave birth to the famous and extremely defensive European-style bastion.

But this thing, at this time, the Ming Dynasty is still a new thing, and the Ming Dynasty's artillery is made back and forth, nothing more than the barrel is thicker and thicker, the iron bullet is bigger, and the gunpowder is more sufficient.

So much so that the cannons that were built often weighed several tons and could not be used in field battles at all.

Not only is there a lot of difference between theoretical knowledge and the West, but in terms of production level, many Ming craftsmen still rely on experience to estimate.

So much so that a small amount of these words are often seen even today.

This is simply fatal in terms of the accuracy and firepower of the ordnance.

"My lord, the ...... That cannon, Song didn't understand it, but the grenade had already been developed! Speaking of which, Song Yingxing was a little embarrassed.

After all, this grenade has been in use in the Song Dynasty hundreds of years ago, although it has not been popularized due to the limited power of gunpowder and the lack of production technology.

But at least there is an epic record, and now there is a new type of black powder provided by Liu Hongji, coupled with the innovation of cast iron technology, it is not difficult to make it again.

"Oh, bring it to Ben Hou!" Liu Hong gradually showed an excited face.

Grenade, the most intuitive scene of this thing is that when fighting devils in later generations, the great warriors of the Eighth Route Army held a grenade in their right hand, opened the seal letter with their left hand, and then the little devil was blown up all over the sky......

Wouldn't this thing be invincible in close combat with the musket?
