However, although the main direction of attack of the Ordnance Institute was firearms, the results were not very satisfactory.

There is no way, the information books that Zhao Heng took out are only the foundation of the foundation in the later generations, none of them can involve the high-tech field, let alone any information related to firearms.

Although as early as two years ago, according to Zhao Heng's limited theoretical level, the Ordnance Institute had already made earth gunpowder, but it was basically used to make fireworks.

It was not until the second half of last year that improvised muskets such as muskets and three-eyed guns, as well as improvised mines such as stone mines, ceramic mines, and pig iron mines, were initially produced.

At the beginning of this year, the Tiger Squat Cannon was finally successfully developed, but in terms of range and power, it still needs to be further improved and adjusted.

In addition, due to the limited level of technology, it is still difficult to produce in large quantities in a short period of time.

To be honest, Zhao Heng himself is not an engineering student, although with his knowledge far beyond this era, he can give guidance on the general direction of the Ordnance Institute, but the real implementation and research still depend on those technicians.

For example, arquebuses and flintlock pistols, he can only tell the technicians some basic principles, as for how to make them, he doesn't know himself, so he can only rely on those technicians to study and experiment.

Because of this, the progress of research and development of firearms is not as fast as imagined.

"Xiao Langjun, what are these three words?"

Ying Zheng looked at the three big characters on the plaque, and asked Zhao Heng suspiciously.

"This is a shorthand character, which is not only much simpler than the small seal, but also easier to identify, which is very suitable for education popularization."

Zhao Heng said with a smile.

In just three years, with simplified Chinese characters and pinyin, he has made more than 10,000 villagers in the entire Walled City completely take off the hat of illiteracy.

"Xiao Langjun, who did you learn from?"

After a short silence, Ying Zheng asked with a strange expression.

In the three days he came to the Walled City, the young man in front of him really brought him too many surprises.

Although this young man's words were quite disrespectful to him, not only falsely saying that he would die of illness in a few months, but also arrogantly saying that Great Qin would die, and even planned to erect a flag to rebel after Qin's death, he did not have any murderous intentions against him.

If it were someone else, even if there were a hundred heads, they would have been cut off by the Black Ice Platform a long time ago.

Zhao Heng gave Ying Zheng the feeling that he was not only a genius, but also extremely mysterious, and could even be said to be supernatural.

Not to mention other strange things, just hybrid rice, potatoes, sweet potatoes, white salt, and paper are enough to be called a merit in the present and in the future.

It can be said that anyone who can have one of these will surely bless future generations.

However, Zhao Heng could take out one of the same casually, and it seemed that it was all insignificant to him.

At this moment, a name suddenly appeared in Ying Zheng's mind, Guiguzi!

Zhao Heng did not answer Ying Zheng's question, but looked up at the sky with a faint smile, and then directly raised his steps and walked into the scientific research institute.

"Your Majesty, could it be that he is really ......"

Looking at the direction in which Zhao Heng disappeared, Wang Jian asked in a low voice towards Ying Zheng with a look of surprise.

It's just that before he could finish speaking, Ying Zheng directly waved his hand to stop it.

Immediately, the two also followed into the scientific research institute.

……

At this time, in a small city dozens of miles away from the walled city.

"If you continue to search, you must find Your Majesty!"

Li Si ordered with an ugly face.

"Whoa!"

Dozens of soldiers were ordered to leave.

"Li Xiang, it's been three days, why haven't you found Your Majesty yet?"

Zhao Gao on the side, with a somewhat complicated look in his eyes, asked Li Si.

Three days ago, His Majesty the First Emperor suddenly disappeared with Wucheng Hou Wang Qian.

They searched for three days and three nights, but they could not find the slightest trace of the two, as if they had completely disappeared from the world.

"The army has begun to search the mountains, and whether we can find any traces of Your Majesty should be known in these few days."

Li Si's brows furrowed slightly, and he said.

"What does the Black Ice Platform say?"

Zhao Gao asked again.

"The people of the Black Ice Platform have already dispersed, and there is no way to know what the result is."

Li Si shook his head.

The Black Ice Platform belongs directly to His Majesty the First Emperor.

Even if he is the left minister, he can't ask anything about the Black Ice Terrace.

The Black Ice Platform is composed of three hundred Iron Eagle Warriors, all of whom are the most elite Old Qin warriors.

It has the supreme reputation of "Qi's skill attack can't meet the warriors of the Wei clan, and the warriors of the Wei clan can't meet the sharp warriors of the Qin clan"!

The Iron Eagle Warriors are all one of the hundreds, and they are only under the orders of His Majesty the First Emperor.

"Shall we just sit back and wait?"

Zhao Gao said anxiously.

He knew very well in his heart that if something really happened to His Majesty, whether it was Li Si, him, or anyone else, they would all die!

He finally climbed to his current position step by step, and naturally he didn't want to die.

"Your Majesty is protected by heaven, and there is the old general Wang to protect him, there will be no incident!"

Li Si affirmed.

"I, Zhao Gao, don't believe in the sky, I only believe in myself!"

Zhao Gao's eyes flickered and said.

With that, he got up and walked out of the house.

"Someone!"

Li Si pondered for a moment, and then ordered again: "Recruit 100,000 villagers, cooperate with the three armies to search the mountains, and in addition, strictly seal the news of His Majesty's disappearance, and those who dare to spread rumors will destroy the three clans." ”

……

Research Institute, Ordnance Administration.

"Xiao Langjun, this is the real artifact you are talking about?"

Wang Jian pointed to the rows of long knives shining with shimmering cold light in front of him and asked.

"These are just appetizers, so you can pick a handful if you like."

Zhao Heng shook his head with a smile.

Since the firearms have not yet really taken shape, the main weapons that the city guards are now equipped with are still these Qi family knives.

"Is this an iron knife?"

Ying Zheng picked up a Qi family knife, looked at it carefully, and asked with a surprised expression.

"Yes!"

Zhao Heng smiled and nodded.

He admitted that in terms of forging technology, these Qi family knives were indeed inferior to Daqin's top-grade bronze weapons.

However, the advantage of iron knives is that they are not only low-cost, but also can be produced quickly and in large quantities.

What's more, the divine object he spoke of was a real weapon of great destruction!

"Lao Zhao, Lao Wang, the cost of these iron knives is less than one of the bronze weapons, and no matter how much is needed, my walled city can be made in a short time."

Zhao Heng said with a smile.

Hearing his words, Ying Zheng and Wang Jian both had their eyes lit up.

If that were the case, it would be fine to replace the bronze weapon with this iron sword.

Then, the three of them moved on.

After a few moments, they came to a rather spacious clearing.

"What is this?"

Wang Jian looked ahead with a puzzled look, only to see that there was something similar to a chariot there.

On the chariot, there is an extremely thick and long copper pillar.

Ying Zheng and Wang Jian had naturally seen chariots and copper pillars, but they didn't know why Zhao Heng wanted to combine the two.
