"Minister Guo, I'm relieved when you say that, haha, you've been talking for so long, a few people please, the conditions here are simple, so the place to live is more ordinary." Gongsun Bai hurriedly smiled and made a gesture of please.

"No, no, we'll trouble you not to talk about it, so you can't eat white pigs for nothing, we have brought you good things this time." Guo Ming said with a smile.

"Oh? What's good? Gongsun Bai asked with some surprise.

"I can't tell you this for the time being, let's go to your barracks." Guo Ming smiled.

Gongsun Bai didn't ask, what he couldn't say, it meant that the degree of secrecy of this thing might be relatively high, the team of the mission was very large, and obviously the things they brought over were obviously not just this secret thing.

"But we have also brought you a lot of the food you want, we can keep half of it, and we can buy the rest when we enter Persia, and by the way, we will also bring you a lot of beef jerky and mutton jerky." Guo Ming smiled and said, "It's more difficult for you to replenish the meat here, and putting some of these jerky in it when you cook every day can allow you to replenish the meat." ”

"Thanks, thanks, that's great." Gongsun Bai immediately looked excited.

It is indeed difficult for them to replenish their meat here, not that there is no grazing, the surrounding land is only suitable for grazing, but the sheep that can be bought by grazing are relatively small, and it is impossible to get all kinds of supplies like those friendly troops stationed in other positions.

It is indeed difficult for them to replenish here, so many of the sheep they buy are raised first, and the meat is replenished every three or five days.

And now with these jerky, it will be much simpler, these jerky is the military rations developed in the fourth year of the Han Dynasty, mainly after touching the salt and drying the jerky, the jerky can be stored for a very long time, and even in the dry place for a few years without any problems, but also can preserve a certain amount of nutrients.

So later, they began to make and hoard such dry food on a large scale, which was divided into beef jerky and mutton jerky, and almost all the sheep flocks controlled by the Han Dynasty every year have been made into jerky.

The number of beef jerky is relatively small, mainly because the herd is in the midst of a big expansion, so the number of beef jerky is relatively small.

However, after having jerky, the amount of food that can be carried by these cavalry and other armies is much more, mainly because these jerkys can be eaten directly, or they can be eaten after boiling in water, which is anti-hunger and not easy to spoil.

So there is still an increase in their combat effectiveness.

With Guo Ming, they returned to the barracks, and some of the things carried by the mission were also directly carried in. The military camp was not outside the city, and Bard City was originally a small city that was not very large, and after the White Tiger Army took the city, the remaining population of the entire city at that time was less than one-tenth.

This place originally belonged to the border area between Persia and the Turks, and was originally under the control of the Turks, but there were originally about a third of the Persians here, and when the White Tiger Army took control of this place, all the Turks left, leaving a small number of Persians, and many other Persians also left.

Because they don't know who controls the city.

The place currently occupied by the White Tiger Army is the City Lord's Mansion in the original city, there are walls here, and there are also many residential houses, mainly because there is a large enough open space in the back, which can make some training and other aspects of the White Tiger Army more convenient.

It was also more convenient to keep it secret, so even after many members of the Patrol Division came over, the entire city was more safely controlled by the Han government, and their White Tiger Army station did not leave.

However, there are not many White Tiger Army stationed here, only one regiment is a thousand people, but not far from Bad City, about a hundred kilometers, there is a division of the Suzaku Army stationed there. Because there is an oasis there, there is enough pasture to supplement the large number of horses of the Suzaku Army.

If you stay in Bard City, the forage needed for the main horses is a huge problem.

"Minister Guo, what did you just say?" Gongsun Bai asked with some curiosity.

"Go and call someone in." Guo Ming looked back, and an assistant who followed him quickly went out, and then two people quickly came in outside.

These two people were wearing ordinary clothes, but after coming in, they saw Gongsun Bai and the two of them directly saluted: "I have seen the general." ”

"Hmm." Gongsun Bai gave the two of them a military salute back.

"Introduce yourselves." Guo Ming said with a smile.

"Report sir, we are subordinate to the Information and Communication Group of the Military Department, Captain Hu Zhiguang."

"Second Lieutenant Qian Ba." Both men spoke loudly.

"Information and Communications Team?" Gongsun Bai was stunned for a moment.

"Yes, sir, we are responsible for operating the nation's newest communications device, radio communications." Hu Zhiguang said in a loud voice.

"Radio communication, talk about it." Gongsun Bai's interest immediately came.

"Radio communication is the use of electricity through different equipment to transmit radio waves, through radio waves to carry out long-distance communication contact, at present we do not have a super large radio station, so our current maximum transmission distance can only reach 1000 kilometers."

"However, at present, Yaochi City is building a large-scale radio receiving device, and after the construction of Yaochi City is completed, we can directly contact Yaochi City here, or directly contact Yumen Pass through Yaochi City."

"How long will it take to contact Yaochi City?" Gongsun Bai immediately asked, they are close to 2,000 kilometers away from Yaochi City by land, not to mention Yumen Pass.

"Immediately." Hu Zhiguang smiled.

"Immediately?" Gongsun Bai was stunned for a moment.

"It's a bit exaggerated immediately, about a minute or so, through the relay, our information can be directly transmitted to Yumen Pass, but at present, the large-scale radio receiving device in Yaochi City has not been successfully built, we have set up two radio receiving stations in the middle, and it will take about 5 minutes to transmit to Yumen Pass, which is a bit slow." Hu Zhiguang said.

Gongsun Bai's whole person was speechless for an instant, five minutes, you tell me this is called slow? Do you have any misconceptions about slowness? Do you know how long it took for us to pass the news to Yumen Pass here?

Even if it is a post station of 60 kilometers as a transit transmission, and then all use the best war horses of the Han Dynasty, the speed is about 60 kilometers per hour, and the information is transmitted in an infinite relay, and it takes about 4 days to get from them to Yumen Pass for almost 4,000 kilometers.

This also requires the support of countless post stations, and if there are no post stations, this speed will take at least seven or eight days to arrive.

You can deliver the message in 5 minutes now, do you call this slow? What if you're slow? And what about other countries?

"That's a good thing, how do you use it?" Gongsun Bai immediately said, "Does this need to be kept highly secret?" He added.

"Secrecy requires secrecy, but if it is highly secrecy, there is no need for it, and there are quite a few people who know about it, and it may be possible that it will be directly opened to the people in two or three years." Guo Ming thought for a while and said.

"Open to the public? This...... Unlikely, right? Such a thing is too helpful for applications on the battlefield, and if it is open to the people, what if the secrets are leaked? Gongsun Bai was a little surprised.

"Don't worry about this, don't worry about the leakage of this thing, the technical difficulty required for this thing is too high, it's not an exaggeration to say, you gave everything to Datang for this thing, it is estimated that Datang can't figure it out, no one explains, they can't make it in ten years."

"And it's useless to just make this, they have too many problems to solve." Guo Ming said with a smile, "Actually, I don't know much about these things, if you ask the two of them, I guess they know more than me." Guo Ming pointed to Hu Zhiguang next to him.

"Then will the two of you belong to our White Tiger Army in the future?" Gongsun Bai's eyes are shining, such people are talents.

"Sir, we can only stay here for half a year, and we have a task in half a year, at least we have to train more than twenty communication soldiers for you, sir." Hu Zhiguang said helplessly, now there is a shortage of talents in this field in the whole country, and Hu Zhiguang and they cannot stay here all the time.

"I understand, in this case, tomorrow I will select talents to teach you classes, and I don't want twenty people, in this way, I will let everyone come to you to give it a try, if you think they have this talent, you will teach them all, how about it?" Gongsun Bai said quickly.

They don't have a lot of tasks at the moment, so they have plenty of time and manpower to learn.

Twenty people, how can Gongsun Bai think it, at present, there should be more and more such people, from Hu Zhiguang and they have to go back Gongsun Bai knows that there are not many such talents.

So they naturally want to teach more, and one more means that they have an advantage.

"Yes!" Hu Zhiguang naturally did not object, his task was to teach at least twenty, but naturally the more the better.

"Then you take a break today and start teaching tomorrow, then Minister Guo, you negotiate this time...... Is it related to radio? The prosecutor thought for a moment and asked.

"Yes, we have conducted a test, the distance from the Persian capital to here is about 900 kilometers, this distance, our information can be transmitted directly, and when the time comes, we can immediately reach a message transmission with Yumen Pass, which is also beneficial for the next negotiations." Guo Ming nodded.

"Understood, then what do we need to do, I'll let people deal with it immediately." Gongsun Bai said with a serious face.

"You just listen to them, I don't understand this." Guo Ming shook his head.

"Sir, we need to build a tower made of steel next to one of the tallest buildings, and we need to build a concrete platform first." Hu Zhiguang immediately took over and spoke.
