"Radio communications, mid-wave band?"

Martin tapped in front of his laptop, a series of ripples that rippled up and down in front of him.

"I'm just an IT person.,Although I know a little bit about IFI or something.,But this thing.,I don't even have a physical thing.,How can I learn it?"

After playing on the keyboard for a long time, Ma Tian threw a thick book in his hand in a huff.

Principles of Radio Communication—Huaqing University Press.

After throwing the book away, Martin's eyes rolled, and then he skillfully switched an interface.

The white flesh of a woman appeared on the computer screen, accompanied by some kind of moaning sound.

"A combination of work and rest, a combination of work and rest."

Martin muttered quietly as his hand reached for the drawer on the side.

After a while, with a tremor of his body, he will enter the state of a saint, and at that time, if he reads the book again, he may have an understanding.

At this moment, suddenly next to Ma Tian's computer, a black walkie-talkie sounded a sharp chirp.

"it!"

Ma Tian fell back and fell heavily to the ground.

…………

Leng Hao is learning paramotor driving, as a winner in life who has fought against the king of soldiers, Leng Hao is now full of confidence.

If you let go of all kinds of movements, it will be easier to drive.

"Actually, it's not impossible to shoot paramotors in the air, but you have to master certain skills, and I seem to have figured out a little trick."

Just as Leng Hao frowned, feeling the wisp of inspiration in his mind, suddenly hurried footsteps sounded behind him.

"Captain, the commander of the first company, Zheng Ximing, sent a communication, and they were surrounded by the Amida protozoa cluster!"

Ma Tian, who was twisting his waist, limped over, and beside him, Song Xiaya, Wang Wei and others also came.

"What's going on?"

Leng Hao frowned.

Before the three teams set off, they all carried rechargeable walkie-talkies that the Rat Expedition had found.

By placing a hot air balloon transfer station above the base of the hydropower station, communication can be achieved within a range of 50 kilometers without interference.

And now, Ma Tian looked at the noisy walkie-talkie and wanted to cry without tears.

"There was a voice just now."

Leng Hao didn't care about Ma Tian's crying face, but instead glanced at Gong Zhiyun on the side vigilantly.

There are no other signals in the last days, and the distance of use of walkie-talkies has increased a lot.

And the appearance of this murmur can only mean one thing, the number of Armida protozoa is definitely not a lot.

"Hey, base, I'm a company. Our ministry was ............"

At this time, a loud intercom suddenly came out of the intercom.

"Hey, I'm Leng Hao, report your location and battlefield situation!"

Leng Hao grabbed the walkie-talkie and yelled.

"We, we're in the middle of the mountains...... passing through the ...... of National Highway 332. There's a huge launch ...... on this side of the mountain."

"There are tens of thousands of Amida protozoa ...... here, and our troops will fight to the last man......"

Listening to the noise on the walkie-talkie, Leng Hao's eyes turned red all of a sudden.

"What bullshit fight to the last man, you are not allowed to die!"

"Retreat immediately, retreat immediately, the base will come to your rescue immediately!"

"Save your strength and wait for rescue!"

Leng Hao almost shouted at his throat.

This is the team he pulled up with great difficulty, and there must be no problem!

At this time, Ma Tian and Song Xiaya beside Leng Hao also gritted their teeth one by one.

Zheng Ximing's company, but the veterans of the rat expedition team are the mainstay, Zhang Yi, Zhao Feng and many old people are in that team.

"Get the map, quick, look for National Highway 332!"

Just as people were looking for a series of traces, suddenly the walkie-talkie rang again.

"Captain, I'm Zheng Ximing."

"Our troops have now retreated to a small mountain village in the mountains. The road directly ahead was completely blocked by the Armida protozoa. ”

At this time, Zheng Ximing's voice was extremely clear.

"Immediately report your location, food and ammunition reserves, the situation of the enemy!"

Gong Zhiyun shouted loudly.

Soon, through the walkie-talkie that suddenly became clear, Leng Hao and the others finally learned about Zheng Ximing's current situation.

The company had only about 4,000 rounds of ammunition left, and they had already withdrawn into a small mountain village with only a sheep's intestine trail as a whole, and were using the terrain to block the enemy.

"We can only, hold out approximately, probably, for four hours."

"Captain, it's not there to rescue us."

Listening to Zheng Ximing's somewhat sad and desperate voice, everyone present was silent.

After going out to explore for at least five days, National Highway 332 is at least seventy or eighty kilometers away from the hydropower station base.

Reinforcements from the Rat Expedition could not have arrived within four hours.

"On behalf of all the soldiers of our company, I would like to say sorry to everyone."

"Captain, we'll see you in the next life!"

Through the walkie-talkie, Leng Hao heard Zheng Ximing, and there were more desperate shouts of fighters.

"I'm from Nyima!"

Feeling Zheng Ximing's farewell voice, Leng Hao was so angry that he almost threw the walkie-talkie in his hand.

But just when Leng Hao's whole body was hot, out of the corner of his eye, he suddenly noticed a paramotor not far away.

The roads in the southwest of China are tortuous, and even if there are roads connecting them, there will be a long detour between the two points.

However, if you use a paramotor, all these difficulties will be gone.

"Hey, Zheng Ximing, I order you not to give up on yourself, you must stick to the end!"

"We have reinforcements, we have reinforcements. We have air force units! ”

Leng Hao's voice undoubtedly reached the ears of the soldiers of the company who were doing the final pre-war mobilization.

"Air Force?"

"Paramotor?"

Zhang Yi, who originally exuded a lifeless aura all over his body, suddenly widened his eyes and yelled.

"Just drop us ammunition with a paramotor. Nima's, we won't die, we won't die! ”

Soon the people reacted and shouted excitedly in the valley.

"What are you doing standing stupidly, hurry up and block the mountain pass, do you want to captain them and they are airdropped at a group of Amida protozoa?"

Zheng Ximing also yelled excitedly at this time.

When Zhang Yi and the other warriors were running towards the sheep intestine path with enthusiasm, Zheng Ximing turned his head and set his eyes on Ye Huanying on the side.

The two fighters beside him quietly approached the handsome college student.

"Who the hell are you? How can they debug a clear radio signal in the encirclement of these Amida protozoa? ”

Zheng Ximing's eyes were full of doubt.

At this time, Ye Huanying smiled slightly.

"It doesn't matter who I am. Company Commander Zheng, I want to remind you. ”

"As those Armida protozoa get closer, the communication of this walkie-talkie will still fail. You'd better explain the situation to your reinforcements as soon as possible. ”
