About ten minutes later, Yu Feiyang carried a black suitcase in his hand and walked in with a tall young man. The young man was wearing a military uniform, but he didn't wear a military rank, so he couldn't tell any level. Xu Zhi's eyes swept over the young man, and his eyes immediately fell on the suitcase in Yu Feiyang's hand, because he had heard that the signal was coming from this suitcase! However, because the sound was sometimes strong and sometimes weak, it made people feel that the sound was coming from different places around him.

"Report to the captain!" Yu Feiyang said with a hint of anger on his face, "Our special observer is a fake! If nothing unexpected happens, the signal source is contained in this suitcase."

"Congratulations! Captain Wu..." said the young man with a smile, "You have passed the first test. You actually found out that I was a fake in such a short time and found the signal source. It was beyond my expectations!"

Wu Hairong glared at the young man, ignored him, and asked Xu Zhi: "Xu Zhi, is it this box?"

Xu Zhi nodded.

"Who is he?" the young man was stunned and looked at Xu Zhi and Huang Minghui and said, "The information I gave me does not seem to be the two of them!"

"Don't worry about this!" Wu Hairong waved his hand, "When I got to my submarine, it was my soldier."

"No wonder!" The young man suddenly realized, "I said, how could you find the signal so early and find the torpedo close to you! It turned out that it was all relying on foreign aid!"

"What's wrong with foreign aid?" Wu Hairong sneered, "Do you not use despicable means to pretend to send observers to sneak into my submarine in advance?"

Speaking of this, Wu Hairong did not forget to add, "And, the military exercise command has not notified the time for the official start of the military exercise."

"Since it's a war, who will give you accurate time?" the young man said with a smile, "Captain Wu is thinking too much."

"Captain..." Xu Zhi reminded carefully, "He is delaying time!"

"Hmph, I know!" Wu Hairong snorted coldly, "I hate their despicable and vulgarity! Xiao Zhou, come and open this box!"

"Oh, by the way, Captain Wu," said the young man flawlessly, "I forgot to tell you that there is explosives hidden in this suitcase. If it cannot be decoded and entered, it can only be destroyed by force, and this explosives can blow up the entire submarine!"

"Can you be more despicable?" Wu Hairong was amused and crying, "Your suitcase has obviously undergone a safety inspection. You can't just rely on your words to indicate that there is explosives inside, right?"

"On the battlefield, the enemy's methods are omnipresent. So what if there is security check? Do you dare to take this risk?" the young man replied confidently.

"Of course!" Wu Hairong's face turned apart and said coldly, "If you can still stand here and talk to me on the battlefield? Come on, give him chili water!"

"Haha, Captain Wu, don't say any extra words!" The young man knew he was in the wrong and smiled, "This second test is decoding. You should hurry up. If the torpedo is really coming, you will lose!"

"It's not easy to decode?" Wu Hairong looked at Xiao Zhou and other technical soldiers to connect the decoder to the suitcase. As a group of numbers flashed on the decoder, he said coldly, "It's up to my soldiers to handle it every minute."

"If it's as simple as you think, what else can our navy participate in the competition for the whole country!" The young man smiled bitterly.

"What do you mean?" Wu Hairong was stunned and asked afterwards.

The young man shook his head: "I can't say anything before that time, I'm a prisoner!"

"Bad!" Wu Hairong glared at the young man.

Seeing Xiao Zhou and others decode, the young man was a little puzzled and asked Wu Hairong: "Captain Wu, how did you find me? Before I got on the submarine, I specially tested this signal transmitter. Without high-frequency signal detection instruments, you would definitely not be able to find it! According to my idea, you have to wait until the torpedo is approaching and find something wrong. Then after hiding, you will find that the location is leaked and finally find me. And at that time, there is not much time left for you. But now... you have more than half an hour!"

"That's our great blessings!" Wu Hairong smiled, "There is a lucky star on our submarine! He can hear high-frequency signals!"

"Impossible!" The young man looked at Xu Zhi with his eyes and shook his head, "Even if he could hear so many signals on the submarine, could he tell it?"

"He has been listening for several days!" Wu Hairong smiled, "Suddenly he can tell the difference by joining your signal!"

"What's your name?" the young man looked at Xu Zhi and asked.

Xu Zhi answered honestly, and at this time, "Crack..." There was also a crisp sound from the suitcase. The decoder stopped and the lock of the suitcase was indeed opened.

Xiao Zhou carefully lifted the box. Sure enough, except for a black flat box, there were a few tubes as thick as fists, and there seemed to be some pigment inside.

"There are really bombs!" Wu Hairong looked at the pigments and whispered.

"Congratulations, Captain Wu..." the young man didn't answer, and said with a smile, "You have passed the second test. However, the third test is the real test. This box is the signal generator, but if you want the signal to stop, you must use computer technology to break through a defense inside and find a set of numbers hidden on the screen. Otherwise, within ten minutes of opening the box, the signal generator will explode and the submarine will explode immediately..."

"Didn't you say we've been almost half an hour?" Yu Feiyang also gritted his teeth.

"The truth is empty, and the weakness is real. This is what our ancestors in China said. You believe me as a prisoner!" The young man replied with a smile.

"Technical soldier, hurry up!" Wu Hairong was too lazy to tell the young man and shouted hurriedly, "Cracking the numbers inside!"

"Yes!" A tall and thin soldier behind Xiao Zhou responded, stepped forward a few steps, lifted the box upward, and a screen was revealed, and under the screen was another thing that looked like a computer keyboard.

"What is this?" Xu Zhi looked at the screen with some wonder, because on the screen, a string of green numbers that looked like 01 fell like raindrops, filling the entire screen.

The tall and thin soldier sat in front of the box, and his hands were typing on the keyboard like playing the piano. With the rhythmic sound of the keyboard, a small interface appeared at the bottom of the screen, and letters appeared on it. As the letters appeared, the green numbers on the screen began to change, either turning into raindrops or falling like floating catkins. Although Xu Zhi couldn't understand it, he knew that this was cracking down on some defenses, right?

However, as time passes by, the green numbers on the screen never decrease. Sometimes they are about to fade and disappear, but in a flash, the entire screen is covered with green again, and the numbers appear like grass from the green.

Wu Hairong looked at the watch anxiously and again at the voice, and beads of sweat appeared on the forehead of the tall and thin young man.

"Three minutes left~" As if deliberately increasing the tension, the young man reminded, "In three minutes, the suitcase will explode!"

"Isn't it okay to remove the explosives?" Wu Hai couldn't help but curse.

The young man shook his head: "It's useless. This explosion is a self-destruction set by the signal generator itself, and it has nothing to do with the explosives! Oh, there are two minutes and forty seconds left!"
Chapter completed!
