Besides, at this time and that time, if his daughter really enters His Majesty's blue eyes, who knows if he will make an exception when he is happy.

Moreover, as long as you can give birth to an heir, you will be the queen mother in the future, and you will be the new emperor's foreign family, and you will be able to soar.

The selection system was also fixed by Liu Zhi, and the palace maids were recruited once every five years, as for the draft, he really felt that there was no need to be too diligent, and he couldn't be busy with too many women.

He still has to take care of this little body, but don't be sucked dry.

So he changed the ancestral system to five years once every three years, and ordered that if he already had children, the emperor would stop choosing concubines after the age of forty.

As for the reason, of course, it is high-sounding, and when you get older, you will have a prince again, and you will be too spoiled, and it is easy to have the urge to replace the prince, causing the court to be shaken.

In the history of the Han Dynasty, such precedents can be said to have occurred frequently, such as the founding emperor Liu Bang, who almost abolished the crown prince and established the son of Mrs. Qi.

This caused chaos for more than ten years, and later Emperor Wu was the same, no matter how wise and martial the emperor was, it was difficult to get out of this strange circle.

Liu Zhi asked himself a mortal, it was completely borrowed from the light of later generations, and in terms of pattern and talent, he was really not as good as Gaozu and Emperor Wu.

Therefore, it is very necessary to set the system while the mind is still sober.

At the moment of this order, the government and the opposition were full of praise, and Yishui's words of praise were all praising him for his wisdom and martial arts, and he was a benevolent, righteous and wise king.

After going through a difficult period of survival, Liu Zhi's pattern has gradually changed, and he is no longer a puppet emperor who is just trying to survive.

Now, he has begun to regard himself as the master of this country, and as the master, he naturally has to think about the survival and development of the country.

When the spring of this year came, Liu Zhi took the imperial guards to Guangchengyuan to hunt under the pretext of taking the imperial guards, but in fact, he was to test the effect of the new weapon.

Tang Heng led people to be busy in the mountains for almost two years, and with the formula and ideas provided by Liu Zhi, he developed ordinary black powder a long time ago.

But Liu Zhi was not satisfied, he dug out his mind to recall, found some clues to stabilize the gunpowder in later generations, and handed them over to continue their efforts.

Although today's gunpowder has been able to sweep the world in the era of cold weapons, it is too unstable and taken out too early, which will only cause serious safety risks.

Therefore, he would rather wait, anyway, it will take time to concentrate power and rectify the rule of officials, and it is better not to fight an unprepared battle.

A few days ago, Tang Heng finally came to report the good news, and finally developed a black powder with a much more stable nature than before.

The reason why Liu Zhi sent him to be in charge of this matter was that Tang Heng was a blacksmith at home when he was a child and was more familiar with weapons, and secondly, he was safe and would not rush in.

Liu Zhi did not put too much pressure on him in this matter, nor did he set a deadline, in order to hope for a satisfactory result.

Hearing that the initial development of gunpowder was successful, Liu Zhilong was overjoyed and decided to personally test the results, so he went to Guangchengyuan to hunt.

The scale of Guangcheng Yuan is much smaller than that of Shanglin Garden, and the area is more remote, with only a few simple temples built inside.

However, the natural scenery of Guangcheng Garden is much more majestic and dangerous than that of Shanglin Garden, with deep mountains and dense forests, and some primitive style.

There are also more beasts in captivity, and for hunting, Guangchengyuan is actually more exciting and fun.

It's just that when Liu Zhi remembered that he proposed to go hunting, the strange faces of the courtiers were a little angry.

Wasn't it just a joke last time in Shanglin Yuan?

Hmph, I haven't looked for the responsibility of your escort, and I dare to laugh at him behind my back.

Things have changed, Liu Zhi is just thinking about it, it is impossible to really find trouble with anyone, but he has learned a lesson, and nothing can be so careless in the future.

Even if you are an emperor and surrounded by servants, there are times when others can't take care of you.

A gentleman does not stand under a dangerous wall, not to mention that he is still an emperor and is concerned about the safety of a country.

Guangchengyuan is a long way, coming and going, Liu Zhi set a time for five days.

Along the way, I enjoyed the scenery along the way, and arrived at Guangchengyuan at dusk, and stayed here that night.

His secret arsenal is hidden in the mountains behind Guangchengyuan.

On the second day, Liu Zhi, who had rested, continued to march with his people, because the mountain road was steep and difficult to walk, so he could only abandon the carriage, ride forward, and plunge into the primeval jungle.

Such a natural scenery is rare to see in later generations, because there are people to protect and be safe, and Liu Zhi still has leisure to enjoy the beautiful scenery along the way.

Fortunately, the arsenal is not far from Guangchengyuan, and I arrived before noon, which is a small horseshoe-shaped basin.

Surrounded by towering mountains, there is only one way in and out, and it is very hidden.

Because it is within the outer range of the Guangchengyuan Royal Forest Garden, and the mountains here are steep, the surrounding hunters and woodcutters are not afraid to set foot easily.

In addition, in the past few years in the mountains, there has been a constant rumbling and thunder, and the mountain people have said that there is a big demon cultivating here.

Those thunderbolts on a sunny day are all because Thor is splitting the monster that has become a spirit, so he doesn't dare to approach it.

Many simple wooden houses were built in the valley, and many craftsmen were busy.

Tang Heng respectfully greeted the outside of the valley and introduced the situation here to Liu Zhi.

"Your Majesty, please see, this is a saltpeter pond, there is a sulfur storehouse, and charcoal is burned on the mountain......"

Liu Zhi visited with him, although it was a little simpler, but it was also a complete weapons factory.

In the end, Tang Heng took him to see the finished product, which was what he cared about the most.

The warehouse is divided into raw material depot and weapons depot, one east and one west are far away, and in the previous research and development process, there were many accidents, two of which were more tragic, and the consequences were very serious.

Although Liu Zhi had warned in advance and stipulated a strict management system, it was a new thing after all, and some costs were inevitable.

The finished product is divided into several forms, thunder, rockets, powder kegs, muskets and artillery Liu Zhi thinks that he is in a hurry, take his time, and has not yet begun to develop.

Among them, the rocket is the easiest, fixing a powder tube at the arrow, igniting the fuse and launching it, and a small explosion will occur after landing.

Due to the small amount of gunpowder, the explosion of the rocket was not very lethal and could only cause moderate damage at best, but its main purpose was to set fire.

And this thing can't be used for individual combat, but for large-scale wars, you think, when the two armies face each other, overwhelming rockets fall from the sky, and explosions come and go.

The momentum alone is enough to make people's hearts break and directly disintegrate people's fighting spirit.

Liu Zhi had dozens of guards experiment with the effect in the open field, and the target was a wooden stake tied with hemp rope.

After three rounds of arrow rain, the smoke was filled, and the sound of explosions was endless, even if Tian Yan's men were all soldiers of a hundred battles, they were still shocked by the momentum of this He, and they couldn't speak for a long time.

It is conceivable that it will only be more exaggerated on the battlefield.

As for the material for the dot lead, a simple version of the match was used, which was not difficult to make, and only red phosphorus was required.

Then, he experimented with fire thunder, which was shaped like a round iron ball with a pattern, similar to the grenades of later generations, but not so advanced.

The same needs to be dotted and thrown like a grenade.

"Boom!"

The violent explosion stunned people, and many people felt that their ears were ringing and they couldn't hear the sound for a long time.

When the smoke cleared, the wooden stakes had been blown away, shattered into countless pieces, and the ground was covered with a small pit of earth.

"Oh my God, it's terrible, if this blows up on people, won't it all be flesh?"

Fan Chao, who was the first to do the experiment with great interest, opened his mouth wide and couldn't close it for a long time.

Where is this human weapon, it is simply a godly method, and it cannot exist at all.

But the facts are all in front of them, and no one can not believe it, at this time, they look at His Majesty's eyes, in addition to admiration, there is more awe.

Your Majesty the Emperor is really inhuman!

What is this, they haven't seen the explosive barrel yet, remember to plug everyone's ears later.

Otherwise, there is a real risk of deafness.

This time they came outside the valley, so as not to destroy the facilities inside, and secondly, it was a basin, and the echo was too loud for the ears to bear.

The group chose a cliff, which was also a special place for Tang Heng to experiment on weekdays, and the surrounding cliffs were blown up to pieces, which looked very terrifying.

Powder kegs are no more lethal than fire mines, multiplying the lethality, and the danger is particularly high, requiring professional personnel to operate.

Therefore, Tang Heng's subordinates came down to demonstrate, a thin young man, carrying a powder keg, skillfully fixed into the pit on the cliff.

Then he lit the fuse, stomped on the cliff with his legs, and his body fell out with great lightness.

The crowd, who had received a stern warning, hid behind a cliff and covered their ears.

Tian Yan didn't dare to be careless, even though he was separated from the cliff, he still let several burly men form a human wall and block Liu Zhi in front of him.

With flesh and blood, a layer of defense was built for him.

Since the last time he was in distress in Shanglin Yuan, as the commander of the imperial guard, he has always blamed himself.

Although the emperor did not blame him, he could not forgive himself and offered to be whipped a hundred as punishment.

Since then, no matter when and where, Tian Yan has been cautious, and he will not let go of any tiny loopholes, for fear of repeating the old things.

Ten seconds later.

"Bang bang!"

The deafening explosion resounded through the sky, sending huge sparks and smoke and thousands of debris flying.

The whole mountain shook as if the earth was about to move.

Even if you have just seen the magical effect of fire and thunder, the power of the powder keg still makes people change color.

This is still a weapon, which is completely comparable to the power of natural thunder.

The huge sound of thunder echoed in the valley for a long time, and the people who were covered with mountain lime and gray faces couldn't react for a long time.

"Good guy, fortunately my ears were blocked, otherwise I would have become deaf directly."

When the smoke and dust stopped, Fan Chao, who was impatient, shook the gravel on his head and rushed out first.

The scene before him was like a miracle, the cliff had disappeared and been sliced away like tofu.

Only rocks and ash were left on the ground.

"This, this, this...... If you take it to blow up the city wall, won't it just blow it up? ”

Liu Zhi smiled slightly, he was very satisfied with this effect, in the current situation, no matter where he attacked, he was already an invincible existence.

The key is that the means are too shocking, if you take advantage of this and launch a blitzkrieg, it can destroy people's hearts while causing huge damage.

It is believed that it will not be long before the Northeast and Mongolia can be recovered, the countries of the Western Regions will be taken, and the Silk Road will be opened.

At that time, he would be able to make a lot of money by trading in silk and porcelain alone, and at the same time be able to buy food from other places, and no longer have to worry about starving to death.

A group of guards excitedly talked around the cliff, they all fought from the frontier battlefield, and knew the difficulty and cruelty of war.

But now all this has changed, with these divine weapons in front of you, fighting a war is purely a one-sided slaughter.

If you want to get military merit, you don't have to fight with your life, you just need to pick up beans.

Thinking about it like this, they suddenly began to envy the Yulin army that was sent to Bingzhou, where they were punished, it was simply a blessing.

Just run a lap casually, and you can get a lot of feats, so it's really not too easy.

After testing the effect of the weapon, Liu Zhi then Shi Shiran went back to the canyon and cleaned it up again, all of them were dusty and dirty, and they were indeed not presentable.

"The results are very good, at the current rate, how much can you produce in a month?"

Hearing that it could be put into production, Tang Heng's face was full of bright smiles.

"Back to Your Majesty, if you re-establish the workshop and leave some things that don't require skills to ordinary craftsmen to do.

He was sure to produce 5,000 rockets, 500 fire mines, and 30 barrels of explosives a month. ”

After speaking, he said a little apologetically, "But this is counting the gunpowder stored before, if the gunpowder is re-produced, then the output of next month will be reduced by at least seventy." ”

Liu Zhi naturally understands that the output of saltpeter and sulfur cannot keep up, and without the help of mechanization, the production process is also very troublesome.

He already thinks it's good to have this kind of production.

"It's okay, in this way, you can increase the production of more rockets, and reduce the powder keg to ten, these quantities are enough."

The main role of the new weapon is to deter, once the opponent loses the fighting spirit, the elite iron cavalry of the Han can sweep away thousands of troops like the infantry.

What's more, there are no particularly tall and strong cities to attack in Liaodong, Liaoxi and the Northern Xiongnu, so just use the powder keg to scare them, and mainly rely on rockets to cover the attack.

Tang Heng was overjoyed when he heard this, the amount of gunpowder keg was the largest, but the amount of each rocket was very small.

"In that case, let's hand over 8,000 rockets next month."

"Haha, that's good, when the battle is over, I'll give you the first credit."

Liu Zhilong looked happy, laughed and patted him on the shoulder.

"Back to Your Majesty, the minister doesn't dare to take credit, this is all Your Majesty's wise idea, the minister just did it."

Tang Heng was born as a eunuch, and it was originally his strength to slap horses, and Liu Zhi didn't care, and he could do things and talk, wouldn't it be more desirable?

In the afternoon, Liu Zhi and his entourage returned to Guangchengyuan, preparing to rest and play there for two days, and then return to Beijing.

And in Guangcheng Yuan, there is also a secret army training......
