"Hurry, Jianguo, tell us how to use this thing?" Ma Guoliang said anxiously.
Xu Jianguo nodded, walked to a nearby clothes rack, and took down his shoulder bag. He pulled out a notebook and flipped to a certain page. He placed the notebook on the table in front of the two men and said, "This is the electromagnetic wave band I recorded. The band on each sample locator is different. As long as I can find the signal from the locator in the fragmentation grenade, it means my guess is correct."
"No, Jianguo, wait a moment. How is the signal strength of this thing? How far is the receiving range?" Ma Guoliang asked.
Theoretically, in the absence of interference and without transmission towers transferring signals, the reception range can reach about ten kilometers.
"Then how can you ensure that the lost fragmentation grenade will be within the signal reception range?" Ma Guoliang continued to ask.
There is no canteen near the shooting range. As far as I know, people from the Military Research Institute and the General Staff still have to come back to the 523 Canteen for lunch. If they really stole the samples, they would definitely carry them with them, so they would definitely be able to search for the signal.
In fact, if Xu Jianguo did not have the map coordinates in his mind, he would not be sure whether he could receive the signal. The existence of the system and space was his biggest secret, which he could not tell outsiders at all. Therefore, if he wanted to make the two of them believe it in the end, he still needed to rely on the electromagnetic wave receiver in front of him.
"Although I still have many questions to ask you, it is more important to first confirm whether the things are still there. Let's start!" Ma Guoliang said.
Xu Jianguo nodded and took out eight "Zhonghua" No. 1 batteries from his bag. These batteries were produced by the State-owned No. 755 Factory in Yuzhou Province of Longxia State. At the same time, it was also the first state-owned enterprise in Longxia State that specialized in the production of dry batteries.
He opened the back cover of the receiver on the table, then put eight batteries in one by one, then closed the back cover, picked up the device and walked to the window, pulled out the two telescopic antennas, then turned the knob and turned on the power switch.
As the power was turned on, the receiver emitted bursts of electric current sounds like a radio. Then, Xu Jianguo adjusted the receiving frequency of the receiver according to the signal band recorded in the notebook.
The moment the band was adjusted, a series of short, rapid beeps came from the receiver. Seeing this, Xu Jianguo nodded in satisfaction and said, "Found it!"
"You found it already?" Dong Jixiang asked. Ma Guoliang looked at Xu Jianguo with some confusion.
"Well, we found it. The receiver successfully received the signal, and the signal is not far from our current location. I have reason to believe that the lost fragmentation grenade should be in the hands of someone in the Military Research Institute or the General Staff!" Xu Jianguo said.
"Jianguo, can this thing determine the location of something? It's useless just by making a 'beep, beep' sound!" Ma Guoliang asked.
Xu Jianguo did not answer his question directly, but picked up the receiver and walked away from the window. Ma Guoliang and Dong Jixiang looked at Xu Jianguo in some confusion, not knowing what he was going to do. But soon, they found something wrong.
As Xu Jianguo moved further away from the window, the beeping sound from the receiver became longer and longer. When Xu Jianguo arrived at the door, the buzzer only sounded once every second.
Then, Xu Jianguo came back from the outer room holding the receiver. As he got closer to the window, the sound of the buzzer became more and more urgent.
Now the two of them finally understood what this machine was doing.
Xu Jianguo put the receiver down and said, "The closer the receiver is to the signal source, the shorter and more rapid the buzzer will sound. Although this won't allow for precise positioning, it should be enough to determine a rough range."
Hearing this, Ma Guoliang clapped his hands vigorously and said, "That's it!"
He stood up, grabbed the phone on the table and made a call. Seeing this, Xu Jianguo quickly turned down the volume of the receiver, while Dong Jixiang still sat on the chair and took out a cigarette box from his pocket.
Seeing this, Xu Jianguo quickly opened the drawer of his desk and took out two unopened boxes of Zhonghua cigarettes. He gave one box to Dong Jixiang and placed the other box in front of Ma Guoliang.
After Dong Jixiang took the cigarette, he smiled and nodded at him, then he opened the package, took out two cigarettes, and lit them with a match.
After extinguishing the match with a wave of his hand, Dong Jixiang stood up from his chair and stuffed one of the lit cigarettes into the hand of Ma Guoliang who was on the phone.
Ma Guoliang took the cigarette and took a deep puff, then gave Dong Jixiang a thumbs up. It was obvious that the two old brothers knew each other's habits very well and knew what the other needed and when, which made Xu Jianguo laugh as he watched from the side.
He couldn't help but recall that Fu Bo and Du Yu treated him the same way in his previous life. Sometimes Xu Jianguo didn't even need to say anything or exchange glances, these two people would know what he wanted.
When Xu Jianguo passed away in his previous life, Fu Bo was still alive, but he was over 90 years old. Because the old man had no children, Xu Jianguo had kept him in his family's villa to live out his retirement. When the two of them had nothing to do, they would often drink tea and play chess together. He was like an old friend.
"I don't know how these two people are doing. The money left to them should be enough for them to live comfortably!" Xu Jianguo sighed in his heart, and suddenly missed them a little.
As the phone was hung up, Xu Jianguo came back to his senses and looked at Ma Guoliang.
Ma Guoliang took a puff of his cigarette and said, "The Secret Service and National Security Bureau will arrive in two hours. Since the people from the Military Research Institute are not under the jurisdiction of the military, the Secret Service will be responsible for the people from the General Staff, and the National Security Bureau will be responsible for the people from the Military Research Institute."
"What should we do with our base? Do we need to impose martial law?" Dong Jixiang nodded and asked.
"I think we should not impose martial law, so as not to alert the enemy. It is better to be loose on the outside and tight on the inside!" Ma Guoliang said.
"Well, that makes sense! I want to see who has the guts to reach out to our Binhai base!" Dong Jixiang said with gritted teeth and a murderous look on his face.
At this time, Xu Jianguo asked, "Commander, do we still need to continue the test this afternoon?"
"Keep going, the test can't stop. Also, let's see if the magnetic grenade will be lost again in the afternoon. But I guess there will definitely be problems!" Ma Guoliang said.
"Okay!" Xu Jianguo nodded in agreement.
"Okay, let's stop discussing this. The people outside must be anxious. Let's ask them to come back quickly!" Ma Guoliang said.
After Xu Jianguo agreed, he stood up and walked outside.
