156 Morse Code

Li Yu completed his thoughts in three or four seconds.

Then he took another two seconds to confirm his judgment.

Afterwards, he looked up at the five people in Class 4.

"You, you, go there, you, you two go there, you follow me, pay attention to the ground and walls, I suspect they have hid in the basement, so the key now is to find the entrance to the basement. If you can't find it, knock it with stones or something, and hear if it's empty below, is it clear?"

"It's clear!"

Li Yu waved his hand!

action!

The six people immediately divided into three groups and searched from different directions.

"You knock on the ground, leave the others to me!" Li Yu said to the brother who followed him.

"Okay!" The guy nodded, then raised his foot and stomped on the ground.

Li Yu looked with his eyes while listening with his ears.

One mind and two uses!

But he is still at ease.

This is the benefit of being a Wolverine.

After searching forward for five or six meters, Li Yu suddenly raised his hand.

stop!

He motioned for the guy who followed him to stop beating.

Just now, he seemed to hear a strange sound, as if there was a hole under the ground, but because the companion was just trampling on his shoes, the feedback was not obvious.

"Find a stone to knock it!" he turned his head and said to the guy.

"clear!"

The guy nodded.

But after looking around, I didn't see the stone, so I pointed the gun at the tiles on a pillar and shot it.

Bang!

The tiles were broken.

He pulled down a tiling from above.

"Knock here!" Li Yu pointed to a place.

The guy then took the tiles and smashed them to the point where Li Yu pointed.

"There should be authentic below!" Li Yu immediately made a judgment.

The two of them then lay on the ground and searched.

Soon, one place caught the attention of two people.

After looking carefully, Li Yu was very sure that it was the entrance to the tunnel, but it was very hidden and difficult to be discovered.

He knocked, but did not respond.

He tried to pry the floor up again, but failed.

Soon, he lay on the ground and shouted, "I am the Chinese Navy, is there anyone inside?"

But he didn't respond even after shouting three times.

At this time, several other people from Class 4 also gathered around.

"The authentic tunnel may have been locked up from inside!" said human.

"They may not hear us inside! So they dare not come out!"

At this time, the team member who had followed Li Yu before said, "Boss, I have a solution!"

After that, he didn't say anything, but just pushed Li Yu away, then grabbed the tiles and knocked them on the ground.

Of course, it’s not just a random typing, but a string of Morse codes!

"Chinese Navy! We are Chinese Navy!"

He typing with Morse code.

This method works very well. After a while, just as they stopped beating, another kind of beating came from below, which was also the Morse code. It translated as: "Chinese Armed Police!"

When everyone heard this, their eyes were bright.

"Call him to open the door!" Li Yu shouted, his voice trembling with excitement!

The team member quickly knocked.

soon.

A rattle.

The tunnel entrance opens.

Li Yu looked inside and saw two armed police officers pointing at them with guns, very alert!

"We are the 568th formation of the Chinese Navy escort formation. We are ordered to pick you up home!" Li Yu said loudly.

When the two armed police heard this, their hearts fell to the ground.

The two of them quickly walked out of the tunnel, and they carefully checked the situation around them until they were really sure that Li Yu and the others were really here to pick them up, and then they completely felt relieved.

"Where are them?" Li Yu asked.

“Below!”

Li Yu walked quickly down the tunnel.

On the other end of the tunnel, more than twenty people shrank together in horror.

Li Yu smiled at everyone: "Hello everyone, we are the Chinese Navy, let's pick you up home!"

Chinese Navy?

When those who heard this, they were stunned.

At this time, the armed police soldier walked to Li Yu and looked at everyone and said, "The Chinese Navy is here to pick us up!"

yeah--

Everyone then waved their arms and jumped up excitedly.

Li Yu walked over and pulled the person in front.

"Okay, from now on, everyone will follow my command. We will take you back to the naval escort formation as soon as possible!"

"Thank you!" A woman suddenly pounced on Li Yu, and tears poured down like rain: "Thank you Navy! Thank you Navy Comrade!"

Li Yu patted her on the shoulder and said with a smile: "It's okay! It's okay! You'll be back home soon!"

The group quickly came out of the tunnel.

Li Yu pressed the radio channel: "Please take care of everyone, prepare to pick up his relatives home!"

"I understand!" Everyone answered loudly.

"The machine gunner stays, others, escort your relatives home, hurry!" Li Yu yelled.

Everyone immediately evacuated in an orderly manner and walked up the stairs.

at this time.

The battle at the door has entered a heated moment!

There are more and more enemies.

The battle is getting more and more intense.

Li Yu quickly came to Zhang Yang.

After looking for a while, he shouted, "Grenade attack is ready!"

As soon as he shouted this, he heard a sound of silence!

"Rockets, avoid!" Li Yu was so scared that he was about to fly. He shouted quickly, and at the same time he pulled Zhang Yang next to him and rushed out to the side.

Everyone has paid great attention.

Luo Zi specializes in keeping with the enemy. Whenever he finds someone suspected of using rockets or fraud, he will immediately start the attack and shoot the head first.

But I still couldn't defend against the enemy's attack.

The enemy stood in a place that no one could see and fired rockets into it.

Swish-

Rockets flew towards the building.
