"I'll find someone to cooperate with you in these areas." Prosecutor Bai nodded immediately.

In fact, the radio station that Hu Zhiguang brought with them, although it is said to be a portable radio, but it is not so portable, in fact, Dahan's current technology, there is no problem in producing the radio station of the World War II period, although the battery may be used for a short time, at most it is an hour or two.

But there is definitely no problem in using it, but these portable ones are not too necessary for the time being, so only about a hundred units were made as backups, and the others were made of the second-level portable ones, which can no longer be regarded as portable.

Although it can be easily carried around, it is actually a large radio station, because it can be connected to an external antenna, such as Hu Zhiguang when they came over, they carried an antenna about 20 meters high, and the antenna was raised by the iron tower built, and a special signal receiving device was installed on it, so as to achieve the effect of increasing the receiving distance.

As for the power problem, there are two solutions, one is to be equipped with a very large battery pack, probably the size of a carriage, but although this battery pack is large, it can store electricity...... It is estimated that it is not as much electric energy as the electric frequency of a car in later generations can store.

In addition, the power generation device of the battery is similar to the hand-cranked generator, but the volume is relatively large, and it can be handed over to the war horse or the ox to pull, and then the speed of the generator is increased by the ratio of the size of the gear to achieve the effectiveness of power generation.

And the radio station is not used for a long time every day, the radio station is the agreed fixed use time, Guo Ming and they all brought the clock out, and they have adjusted the time, although there is a slight error, but the error can be accepted within a few minutes.

The radio station that Guo Ming and they are going to carry to the Persian capital is much smaller, but it can be connected to a very high antenna, and they have tested it, and there is no problem with communication for about 1,000 kilometers.

Mainly because the electromagnetic environment of this world is so good, and after the construction of a slightly larger radio station on the side of Bad City, communication is much easier.

Guo Ming and they didn't stay for too long, after explaining to Gongsun Bai and the others, and leaving the things that should be kept, Guo Ming and they set off again, this time Guo Ming and the number of people they set off was not much, there were only about 200 people in total, of which 150 were escort cavalry.

However, when Guo Ming and them entered the Persian border, there were already about a thousand Persian cavalry waiting here, and the other party came to greet Guo Ming and others, as a substitute for the Turks, becoming the largest country bordering Persia in the entire Western Regions, and the Han Dynasty was actually very shocking to the Persians.

And in their opinion, the Han and the Tang are actually about the same, although these are two countries, but they also know that the Han is one of the most powerful countries in the world, after all, the merchants of Persia have always been doing business with the Tang Dynasty in the Han Dynasty, so they have a lot of sources, and they know very well how strong the strength of the Han is.

In fact, Persia and the Han Dynasty had diplomatic exchanges two years ago, and it was Persia that took the initiative to send envoys to the Han Dynasty, and in the past two years, the trade between the Han and Persia has also strengthened a lot, so this time Guo Ming and others visited Persia, and Persia attached great importance to it.

Therefore, the cavalry team that greeted Guo Ming and them had been waiting at the edge of the border about half a month ago, and among the people who followed Guo Ming and them, there were three Persian envoys who had stayed at Yumen Pass for a long time.

However, when they approached the city of Bad, they got along with Guo Ming and returned to Persia directly after a good time.

After meeting with the other party's cavalry team, Guo Ming and their team, under the protection of the Persian cavalry, went to the Persian capital of Ctesiphon, the two cities of Ctesiphon and Firuzabad, which can be said to be twin cities, both located in the valley of the two rivers, that is, about twenty or thirty kilometers south of the city of Baghdad in later times.

In this era, it is one of the most prosperous stages in the Middle East, after all, the two river basins have supported most of the civilizations in the entire Central Asian region, and Babylon, one of the four ancient civilizations, originated once.

There was another name in ancient Greece, and that was Mesopotamia.

The origin of civilization here is also said to have originated more than 5,000 years ago, but due to the topography, it is difficult for a certain civilization to be passed down all the time, including Egypt, one of the four ancient civilizations near the Nile River next door, which also had a civilization interruption.

The four ancient civilizations have reached the only one China that has completed the cultural inheritance in later generations.

Although the Persian civilization is not inherited from the ancient Mesopotamian civilization, Persia has inherited a lot of ancient books from these civilizations, and it is not backward in terms of culture, technology, art and other aspects.

In fact, during this period, the two river basins and the surrounding areas of the Mediterranean Sea were considered the center of Western civilization, and those places where the traditional European powers were traditional in Europe were now barbaric countries.

Isai III is the current king of Sassanid Persia, he just succeeded to the throne of Persia this year, Isai III is not very old, but not young, Isai III, who is thirty-one years old this year, is actually not high in succession.

But the involution between princes is not unique to China, just like Sassanid Persia, from the time of the rebellion of his son in 628, and then until 634 this year, a total of 6 years have passed, and Sassanid Persia has also changed 6 kings, one a year.

And Isai III was the seventh king, so you can imagine what happened to Sassanid Persia, which was once so powerful.

In this case, Isai III did not have a very strong control over his throne, so he attached great importance to the visit of the Great Han, in fact, the grain exported by the Great Han to Persia this year has helped Isai III stabilize part of the rear.

And this time Guo Ming's arrival, Isai III has already explained to everyone that he wants to greet Guo Ming with the greatest enthusiasm.

Therefore, when Guo Ming entered the valley of the two rivers, he was warmly welcomed, and in the whole city of Ctesiphon, Isai III even made the whole city clean up.

After arriving outside the city, Isai III personally went out of the city to greet Guo Ming, for Isai III so enthusiastic, Guo Ming naturally knew in his heart, the current situation in Persia, Mingyue's security department has given various predictions.

"Welcome Ambassador Guo." To Guo Ming's surprise, Isai III actually knew some Chinese, and he spoke it well.

"Thank you for your welcome, and on behalf of my Han leader, Huo Gang, and the Han government, I would like to express my condolences to Your Majesty." Guo Ming smiled and saluted.

"Thank you, Chief Huo Gang, Ambassador Guo Ming, please." Isë III said with a smile. As for why Huo Gang was not called an emperor or a king, but just a simple leader or leader, there have always been some doubts about this question, but this is all a private matter of the people themselves, so Isai III naturally will not ask it here.

In fact, many people have questions about this question, but no one has asked Huo Gang, so they don't know what Huo Gang thinks.

After entering the royal palace of Persia, Isai III had already set up a banquet to entertain Guo Ming.

At the end of the banquet, Isai said: "Ambassador Guo Ming, your embassy has been successfully established, and I believe that your envoy has already told the emperor of your country that Ambassador Guo Ming must be tired today, how about inviting Ambassador Guo Ming to come back for talks tomorrow?" ”

One of the interpreters next to him immediately spoke Isai and translated it to Guo Ming.

Guo Ming smiled slightly and then said directly: "Thank you Your Majesty for your hospitality and understanding, but we have wasted too much time when we came from Dahan, and the time is relatively urgent, and we are not very tired when we come on the way, so if Your Majesty is not tired, we can actually start now." ”

The translator was slightly stunned, but he translated these words directly to Isai for the first time.

What Guo Ming said was the truth, Guo Ming only took more than a month to go from Yumen Pass to Bad City, but it took almost a month to walk from Bad City to Tai Xifeng.

The roads on the Persian side are worse, and they are within the territory of others, so how far to go every day, Guo Ming and they really have no choice, this is still their way to urge as much as possible, otherwise, it is estimated that the speed of walking will be slower.

So now Guo Ming is still in a hurry.

Isai paused for a moment, and simply said directly: "Since Ambassador Guo Ming said so, then we can start talking now, before my envoy Huo Bar told me that Huo Gang's envoy wants to increase the volume of trade with us, I don't know what it is?" ”

"Your Majesty, in fact, I have come this time with a special mission, one of our Han caravans has been killed in the peninsula region, and we have identified the enemy who killed them." Guo Ming said in a serious tone.

"Oh?! Has Ambassador Guo identified the murderer? Ambassador Guo, please say that if it were me a Persian, I would definitely give Ambassador Guo and Chief Huo Gang an explanation. Isë was stunned for a moment, but he paused, and then immediately spoke.

Guo Ming's mouth is in the peninsula is where Isai knows, these basic exchanges they are still very clear, to be precise, Isai still has a map produced by the Han in his hand, although there is only a map of their Persia vicinity, but that map is extremely accurate.
