It took a lot of effort to choose a location, because it was necessary to find a place that was rarely visited, first, for secrecy, and secondly, for secrecy.

However, relying on the financial and material resources of the Mo family, these are also easy to do. The construction of this experiment is also the top secret of the Mo family, and the whole process is kept secret.

When it was finally done and Huan Lin could take people over for the experiment, it had been almost a month.

This month has been enough for Huan Lin to be anxious. However, Jiang Anrao confiscated his materials, and he could only spend this long month dreaming of experimental plans.

Huan Lin will not dislike the remote part of the new laboratory, and he can do the experiment without distractions.

However, Jiang Anrao still told him some precautions in advance, so as not to waste time on his experiments, and it was easy to injure himself and cripple himself.

"Don't add things indiscriminately, sometimes no matter how harmless things are added to it, it will also react, before any experiment, do a good job of protection, keep dangerous materials away from open flames, record materials before the experiment, proportion, record data during the experiment, and record the results after the test."

Jiang Anrao even specially engraved the rules and regulations on the wall of the laboratory, so that they can memorize them, and they can see them every day when they enter and leave the laboratory!

When Huan Lin saw this battle, no matter how hot his mind was, he also realized that the stakes were very important at this time.

"Jiang Rao? Is this thing so powerful? I've never seen you like this. ”

"Absolutely. So be sure to prevent people from using it indiscriminately. You also have to experiment under the premise of absolute safety, and you must also keep it absolutely confidential. ”

By the time Jiang Anrao's side settled Huan Lin, Jiang Chiyu had already led troops and leveled most of the righteous canals.

Originally, Yiqu did not have an advantage over the Upper Qin State. Now that the king of Yiqu is dead, the sons of the king of Yiqu are also in different places, when the Qin army came, these crowds were leaderless, some surrendered directly, some were killed after resisting, and some fled in a hurry. In the chaos, he quickly lost his resistance.

This battle did not end soon, when the living space of the Yiqu people was compressed to smaller and smaller, they resisted more and more fiercely, this is a battle to stabilize the rear of the Qin State, without Yiqu, when Qin Dongjin advances, there will be no worries.

But for Yiqu, this is a battle of extermination. This descendant of the Western Qiangrong tribe has survived for more than 800 years since its separation, and finally disappeared in the long river of history in the 36th year of King Qin Zhao.

After the destruction of Yiqu, Qin set up Beidi County to govern the place where Yiqu originally lived.

When Northland County was first established, Huan Lin called Jiang Anrao to his laboratory and invited her to watch a fireworks.

It's real fireworks. Jiang Anrao couldn't help but smile as he watched a spark that was very similar to a modern magic bullet bloom in the air.

"Huan Lin, you are really talented!"

There are some things that really can't be stopped.

She never touched these things like gunpowder, but as a result, Huan Lin still made up his own movements, for safety and confidentiality, she got a special laboratory for Huan Lin, and he made up fireworks by himself.

In fact, if she wants to, she can get a lot of formulas and practices from the live broadcast room.

Although the private sector restricts fireworks, after all, some companies have a license to make them, not to mention, she can contact the official of that plane. The taxes she earns for the government every year in this live broadcast room are quite generous, and she also meets some official needs, but she just doesn't plan to get them directly to Huan Lin.

Let him do his own research.

"Haha, Jiang Rao, look, this thing is too good-looking! Guess why my spark is turquoise? ”

"You added copper."

"Huh? How do you know! You know that you're still asking me to do this? Why don't you get it yourself. ”

"I'm just guessing."

Huan Lin glared at her, obviously not believing. But soon I won't get to the bottom of it, just say:

"Hey, it's a pity, this is a far cry from the kind of powerful weapon I imagined. This thing is good-looking, it's not very useful. ”

"Who said that? It's a great thing. You think, back then, the princes had to look at the beacon fire when they were called. If you shoot higher, bigger, or simply make colored smoke, isn't this better than a beacon fire?

The beacon tower cannot be moved, and it is difficult to observe in bad weather. But this thing can be carried by the combat army. A specific color represents a specific signal, which can be seen from a long distance as long as it is transmitted from this side.

In the battle formation, there is this as a signal, and it is much faster than the personnel running over to notify them.

This one is very practical. You can do flares, you should study more. ”

When Huan Lin heard this, he thought it was true.

Nowadays, when various countries go out on the march, there are hundreds of thousands of people at every turn, and the military formations can stretch far apart.

The signal is usually by the flag, or the herald. If you have this thing, it's really more convenient and faster than that.

"Okay, then I'll be responsible for researching more types, and how to choose when the time comes, leave it to those who use it."

[Guest Jiang Ruoyang: An An, when will you come back to Xianyang? ] 】

Jiang's father shouted Jiang Anrao in the live broadcast room.

For safety, the place where Jiang Anrao arranged the experiment for Huan Lin was not in Xianyang City, because she was afraid that the explosions would be frequent and attract attention.

[An An anchor: I'll be back soon. How? Wang Ji is leaving? 】

Since everyone planned to find Fan Ju to have a friendship, Jiang Ruoyang and Jiang Chiyu inquired about the right person and timing.

Recently, the Qin State and Chu Han Wei discussed the matter of cutting Yan, and there were frequent correspondence between the countries, and the confessor was one of the officials responsible for conveying the king's order.

When I heard that there was a confessor named Wang Ji who was going to Wei recently, the Jiang family said it was very good.

Isn't that right? The history books mention the name of Wang Ji, that is, after he visited the Wei State, he got acquainted with Zheng Anping, and then met Fan Ju.

Anyone who goes to another country to deliver a letter doesn't just deliver a letter. In addition to sending letters, it is also necessary to win over officials from other countries to recruit talented people. Advertising and publicity for one's own country are all supporting businesses.

If Wang Ji wants to go to Wei, this step must be indispensable. Since it is to sell favors and win over relationships, it is better for Jiang Anrao to run in person.

Jiang Anrao is ready here, and when the Qin State delegation leaves, she will also take people with her. Since Dad Jiang came to ask, he was about to set off.

All countries in the world call back and forth every day, as if the people are used to it, and the merchants are also used to it, and the trade circulation cannot be banned, so although the caravans will be taxed in various countries, they will not be really embarrassed.

Jiang Anrao plans to take the ink merchant to the Wei State, and now Qin, Qi and Chu have traces of the Mo family, but among the three Jin Dynasty, the Mo family has no strength, Jiang Anrao has long wanted to go to the land of the Three Jin Dynasty to develop and develop, and at this time he wants to go to Fan Ju, and he happened to do two things at the same time.
