Seeing many officials trembling, and some even falling to the ground, His Majesty Li Er was also shocked. He really didn't expect the thunder to be so powerful.

So His Majesty Li Er scolded Yang Fan displeasedly: "Are you planning to kill the king? You didn't tell me earlier that Hong Tianlei was so powerful, but it actually injured so many officials. It's simply unreasonable."

Although the words were harsh, the smile in His Majesty Li Er's eyes could not be concealed.

Originally it was just to scare the family officials, but the effect was too good.

But even though he was prepared in his heart, His Majesty Li Er's face was dull at this time, and he was horrified in his heart.

Faced with the power of Hong Tianlei, it was completely incomprehensible to him with his knowledge. Apart from being shocked, he was still shocked!

If all the armies of the Tang Dynasty were equipped with such artifacts, it wouldn't be easy to conquer cities and lands, and sweep across the barbarians would be just around the corner!

The more he thought about it, the more excited he became. His Majesty Li Er's heart was beating fast and his breathing became heavy.

After hearing His Majesty Li Er's words, Yang Fan suddenly became extremely depressed.

If you don't listen when I say stay away, I'm going to make a big fuss now.

Fortunately, the injured official only had some scratches and was not seriously injured. Otherwise, it would have been difficult to end the incident.

Ignoring Yang Fan's resentful look, Li Er asked the chamberlain to quickly help the injured official aside, and he took several important officials back to the duty room.

As a party involved, Yang Fan was of course also dragged in by Li Erlian.

After being scolded for no apparent reason, and seeing His Majesty Li Er acting so rudely, Yang Fan was really a little uneasy.

Is the emperor really angry?

He secretly looked up and saw Li Er staring at him with glowing eyes.

Li Er trembled slightly and asked, "Is this easy to make and how much does it cost?"

When he asked this question, Li Er felt very uneasy.

If the cost is too high, no matter how powerful it is, it will only be a mirror image.

You know, every time you throw one out, it is money.

Now that the Tang Dynasty is at a critical moment in its development, it cannot resort to violence!

Seeing that His Majesty Li Er did not want to punish him, Yang Fan secretly breathed a sigh of relief and said quickly: "The Thunderbolt is made of saltpeter, sulfur, and charcoal mixed in a certain proportion. The Thunderbolt just now is actually just a semi-finished product.

The amount of medicine is a little less than normal, and there are no iron tablets or other things loaded in, so the cost is less. If calculated according to the original design, it would cost fifty or sixty cents. Of course, if a larger filling is needed

If the volume increases, the cost will increase accordingly.”

"What you mean is that a normal-sized thunderbolt only costs fifty or sixty cents. The bigger it is, the more powerful it is. If it is used on the grassland, those people will not be shocked to death."

His Majesty Li Er's face was flushed, his voice was trembling with excitement, and he clenched his fists to keep his inner peace.

This has to make His Majesty Li Er excited.

Saltpeter, sulfur...none of these things are valuable. One piece only costs fifty or sixty pence.

Doesn't it mean that if one hundred thousand of these thunders were made, it would only cost a few tens of thousands?

If this were to be the case, wouldn't all the peoples on the grasslands have to crawl at my feet?

Seeing His Majesty Li Er's almost crazy look, Yang Fan could certainly guess what he was thinking, but he still ruthlessly broke the emperor's fantasy.

"Your Majesty, although the cost of the Thunderbolt is not high and its power is great, it has several limitations."

"This kind of thing can only work best in crowded places, and even if the amount of gunpowder is increased, it can only be used to attack cities and seize territory. If the opponent wants to run away, you really can't catch them with this thing. It's not as lethal as a musket."

big."

"Moreover, this thing must be ignited through a fuse, which will be limited in humid places and rainy weather. Once it gets wet, it may extinguish the fuse and even affect the power of the explosion."

"The most important thing is that this kind of thing kills people through the broken iron fragments inside. After the explosion, the flying direction of the broken iron fragments is uncertain. If you don't keep a safe distance, you may injure one thousand enemies and damage yourself eight times."

Hundred."

Hearing Yang Fan mention so many shortcomings, His Majesty Li Er couldn't help but feel a little disappointed.

However, this thing can still increase the combat power of the Tang Dynasty army a lot.

Especially when defending the city, if you stand on the city wall, light it and throw it down, and as many as you have will be destroyed.

Or when attacking a city, if you dig a hole at the base of the city, even the thickest wall can be blown open.

Thinking of this, His Majesty Li Er asked the key question: "How much can this thing produce in a day?"

Now that we know the power of Hongtianlei, it would be nonsense if it takes several days to produce one.

Yang Fan did not dare to hide it and said: "Under normal circumstances and with sufficient raw materials, we can produce about twenty pieces a day!"

Twenty a day is a lot!

His Majesty Li Er thought for a while and made a decision immediately: "This thing is too powerful and harmful to the peace of heaven. It must be strictly controlled and cannot flow into the public. If this material is exposed, I will definitely pursue the responsibility seriously."

If such a powerful weapon were to flow into the public, Li Er simply couldn't imagine what the consequences would be!

If someone dislikes him as the emperor and lights one and throws it at him when he is on patrol, then he, the emperor, is still alive?

The more I thought about it, the more hairy I felt, and His Majesty Li Er shivered!

A sword has a double edge. It can hurt others as well as yourself. It depends on the person who uses it.

Yang Fan suddenly stopped working. It was possible for someone else to make this thing with a little more tinkering.

If others imitate it and think it was revealed by him, wouldn't it mean that he has to keep his head in his belt every day?

Of course Yang Fan didn't want to do this kind of unfortunate thing, so he quickly postponed it and said: "Your Majesty, it's up to you to decide how to manage it. Wei Chen has completed the task as a technical director and is now on the right track. Can Wei Chen

gone back."

Seeing that Yang Fan wanted to give up his career again, His Majesty Li Er said with some displeasure: "You are young and it is the time to start your career. If you don't dare to take responsibility when you encounter difficulties, how can you achieve great things?"

"Let's do this. I will set up a department responsible for the storage of Hongtian Lei and muskets. All the outgoing and incoming of these sharp weapons must be matched one by one. Before the production of this batch of sharp weapons is completed, you will be fully responsible for this department."

His Majesty Li Er talked about this. How could Yang Fan dare to refuse again? He could only say with a wry smile: "I obey the order!"

I just hope that the emperor can find someone to replace him soon.

Although it seems that he controls such a crucial department because he has the trust of His Majesty Li Er, it is actually a hot potato!

Not bothering to pay attention to Yang Fangao's displeasure, His Majesty Li Er waved his hand impatiently and asked him to go down first.

Although this experiment shocked the aristocratic family, it also hurt some officials.

His Majesty Li Er will discuss it with several important ministers to see how to deal with it.

If one thing is not handled well, it may give the family the opportunity to counterattack.

****

An experiment not only made Yang Fan a lot of money, but also made Yang Fan famous. Some people even praised Yang Fan to the level of a god.

In the eyes of the people of the Tang Dynasty, only gods could create such powerful weapons.

Yang Fan has gained both fame and fortune, but the aristocratic family is extremely angry.

Not only did they lose a lot of money, but they were also severely stepped on and rubbed by Li Er, which they couldn't bear.

Especially Changsun Chong, who was so frightened that he peed in front of everyone and became the laughing stock of the people in Guanzhong.

In the next few days, Changsun Chong stayed in the mansion and did not dare to go out. Even when he went to court, he could only complain that he was sick, which only increased Changsun Chong's resentment towards Yang Fan.

In order to retaliate, Yang Fan secretly urged Chang Sun Bin to speed up the implementation of the plan.

Yang Fan also stayed in the firearms prison because of Li Er's confidentiality requirements, which also made him extremely irritable. He could only read in the duty room until late at night every day.

Just when Yang Fan was drowsy, someone knocked on the door gently, which suddenly made Yang Fan sleepless.

He raised his head and saw Xi Junmai walking in gently.

Xi Junmai looked at Yang Fan who was reading at night with admiration, and then said excitedly: "My lord, you guessed it right. There is indeed a problem with the Daming Palace pulling so much earthwork every day."

"Tell me about it!" Yang Fan asked calmly and calmly.

When Xi Junmai told the results of the investigation, Yang Fan was shocked.

I really didn't expect that the Firearms Inspector would actually be taken into consideration.

It turned out that the earthworks transported from the Daming Palace were dug out by a group of tomb robbers from a hidden foothill of the Daming Palace after investigation by special forces.

That's right at the junction with the Firearms Inspectorate.

These tomb robbers lurked day and night, and transported the earth they dug at night to the construction site of the Daming Palace, and then the official construction team transported the earth out.

If Yang Fan hadn't felt that too much earth was being transported, he would have noticed something strange.

No one really thought that this group of people would dig a tunnel from the Daming Palace to enter the Firearms Prison.

These people spend so much time and effort, it seems they have great intentions.

Thinking of this, Yang Fan asked: "Have you found out the identities of these people? How long will it take for their tunnels to be dug through the firearms prison?"

"Master Qi, the information obtained through investigation is that they are a group of tomb robbers in the Guanzhong area. The tunnel they dug is leading to the storage warehouse of the firearms prison. According to the progress, it will only take about two days to dig through. Do you want to dig it out?

All of them..."

As he said that, Xi Junmai made a gesture of wiping his neck.
