"Ready to start!" Zhao Qian strode out and shouted loudly.

He carried a cyan cannon barrel in his right arm, a huge iron box behind him, and a long metal pipe and ring bracket dragged under his feet.

"What is this?

"Just this one, can you break the rock wall?"

"It's all rocks, not dirt!"

......

Countless pairs of eyes fell on Zhao Qian, and his gaze was full of doubt and nervousness, as well as deep worry.

No wonder people are skeptical.

Can this thing really work?

It's only an hour, it's not enough to make a handmade ceramic, it can make a terrifying device that opens mountains and cracks rocks? Not to mention, you still need to meet those five rather harsh conditions!

"Can it work?" Zheng Xinzhu looked at Wu Changce.

"I think I can!" Wu Changce nodded firmly, he trusted Zhao Qian.

Click, click, click!

Zhao Qian drove the hoe He over, and then the mecha squatted, but did not turn off the engine, and the black liquid circulating in the pipes all over his body, exuding a rich and scorching heat, and the air was scorching.

"The pulse of the beast is up to you......" he whispered.

Zhao Qian's right palm was cracked, all kinds of welding devices appeared, and his hands were carefully operated, and the silver iron box and the "blood vessels" of the hoe were accurately connected, and he checked them several times, and then he breathed a sigh of relief.

"It should be fine...... he whispered.

It's only been an hour, and Zhao Qian is not an immortal, so of course it is impossible to make a brand new piece of equipment.

However, he can borrow power!

This set of green dragon breath can be used as an accessory to borrow great power in the pulse of the giant beast.

"Get out of the way!"

In front of everyone's eyes, Zhao Qian carried the cyan cannon barrel and walked towards the mountain rock, and after setting up the bracket, he pressed the button.

Tear and pull!

A column of snow-white water spewed straight out!

"Oh? is this...... What's going on? It's just a column of water, with this kind of power?"

"This rock wall...... Probably not!"

"I'll go, that's too exaggerated!"

......

In an instant, everyone's eyes straightened, stunned, and whispered.

What do they see?

The water is like a knife, invincible!

Under the snow-white water column, the rock wall seems to be corrupted, collapsing and disintegrating in an instant, turning into invisible! Like cutting tofu, the water flows in the direction, and the rock wall is cut, leaving deep pits.

There was no vibration, no heat, but the broken rock wall was devastating and decaying, and it was effortless!

In just a moment, the crater in the rock wall was already close to half a meter.

"What? this is ......" The crowd's breath froze.

This scene is so unbelievable that they can't understand it.

"Is it a chemical potion?" Qu Lao couldn't help but say, "What kind of potion is this? Can even stones corrode aqua regia?"

"It's not chemicals, it's water, just plain water. Zheng Xinzhu shook his head.

is not as good as Qu Lao in emergency repair and rescue, but his knowledge is still quite extensive.

Zheng Xinzhu suddenly understood why Zhao Qian named this equipment "Green Dragon Breath".

- Qinglong spits water!

"Water, impossible, this is impossible!" Qu Lao subconsciously shook his head, incredulous, "A mere water column, can it have such great power?"

"Elder Qu, have you ever heard of water cutting?" Zheng Xinzhu's eyes floated and he said in a deep voice.

"Water cutting?" Qu Lao looked dazed.

"I have a friend who does water cutting. Zheng Xinzhu was not surprised, and said slowly, "The so-called water cutting is a 'high-pressure water jet' method, which sprays out the water stream and uses it to cut hard objects. ”

"High-pressure water jet?" Qu frowned.

Zheng Xinzhu nodded and continued: "According to my friend, the pressure of the water sprayed by the cutting nozzle can reach one million megapascals, and the speed can reach several times the speed of sound!

"I think I've heard of water cutting, too...... It seems to be an emerging technology, also known as 'waterjet'!"

"It's only been an hour to make a set of water cutting equipment? Is this something that can be done by man? It's terrifying!"

"Waterjets, not much better than laser knives!"

......

The crowd whispered and chattered, and was amazed.

"However, there is one thing that I can't understand......" Zheng Xinzhu shook his head with a strange expression.

"Which point?" asked Elder Qu.

"In general, waterjets are very small, less than five millimeters in diameter. Zheng Xinzhu's expression was solemn, his face was full of surprise, "But the pipe diameter of this set of equipment is close to the thickness of a fist! With such a large pipe diameter, it is really unimaginable, how much pressure is required!"

Everyone listened and realized something, and a chill ran down their spine.

Pressure is equal to pressure multiplied by area, which is understood by elementary school students.

With such a thick barrel diameter, the pressure required is so high that you can know how terrible it is to calculate it at will!

Zhao Qian was very calm, his eyes were carefully observed, and his expression was calm.

The majestic pressure of the green dragon's breath naturally came from the pulse of the giant beast.

The power of the monster's pulse comes from the super-heavy fluid, the "flowing steel"!

Nowadays, the engine of Hoe He has been replaced with a hydraulic engine, which is driven by super heavy liquid, and the force is up to a thousand jun!

In addition, there are hydraulic motors at the important joints around the body, which work together with the reciprocating circulation of overweight fluid, and the force gradually accumulates.

Once the super-heavy liquid flows, its inertia is huge, and it can continue to push the impeller, and the thrust will become more and more sufficient, bursting out with unparalleled power, which is enough to move mountains and seas!

And the majestic power of hoe He is the "tube of chicken blood" from the pulse of the giant beast.

Of course, the pulse of the behemoth is strong, but it also has flaws.

First, the super-heavy fluid is heavy and stagnant, which requires a slow accumulation rate and an extremely long warm-up time. It takes fifteen minutes after the engine starts before the mech can be put into combat.

The second is that the super-heavy fluid is powerful and has huge inertia, which also causes great damage to the engine and body. With the current state of hoe He, I am afraid that it will be scrapped in half a month and turned into a pile of scrap iron.

The Giant Beast's Pulse is a double-edged sword, and it has a taste of "Seven Wounds Fist", which is why it is not used on the God Killer.

And right now, the green dragon's breath and the pulse of the giant beast are connected, and it may use the huge pressure formed by the flowing steel to shoot out a powerful water column! This water column seems simple, but in fact, the pressure is close to 10 million megapascals, and the speed is even faster than the speed of sound!

Click, click, click!

The rock wall cracked, like boiling water splashed on the ice, and the ice disintegrated in an instant.

Zhao Qian slowly exerted his strength, pushed the folding ring bracket, and pushed the green dragon's breath into the hole one by one, getting deeper and deeper.

After a while, I couldn't see it anymore.

Everyone else was stunned.

......

In the dark, in a criminal investigation vehicle.

The air became less and less, and the feeling of oppression and suffocation was mixed, diffusing bit by bit.

None of the four people in the car spoke.

They also noticed that the air was getting less and did not dare to exert their physical strength, so they tried to sit still and maintain a calm mind so that the oxygen consumption could be slower.

But the quieter it is, the more depressing it becomes.

Everyone can feel it, the feeling of suffocation is getting stronger!

Wait for death!

Every second passed slowly, and the feeling of a slow death made everyone despair.

Yang Liu didn't dare to cry, she covered her mouth, but the tears couldn't stop falling.

Su Yunhan leaned against the car window, his expression a little dazed.

She suddenly looked down and looked at the screen again.

It's still that piece of information.

- "I'll be there soon!"

Will he come?

Su Yunhan hesitated for a moment, and suddenly smiled bitterly.

He is delusional again, there must be a yellow cordon around him, and he can't get in if he wants to.

Are you going to die?

Su Yunhan was confused, but his expression gradually relieved.

It's just a pity that a lot of things haven't been said......

"Yun Han, Yun Han!"

A familiar voice rang out.

"Zhao Qian?" Su Yun shuddered and looked left and right suspiciously.

Delusion?

Her first reaction was that she was too hypoxic and had delusions.

But then, the voice rang out unrelentingly.

"Yun Han, Yun Han!"

It's a police channel!

"Who are you? Which sub-bureau are you?" Lao Qin grabbed the police microphone and said in a deep voice, "Why haven't I heard your voice?"

"Lao Qin, you're looking for me!" Su Yunhan hurriedly took it over and said softly, "Zhao Qian, why are you here?"

She had mixed emotions and wanted to look strong, but she unconsciously had a hoarse voice with a faint cry.

"I'm here to save you!" Zhao Qian breathed a sigh of relief when he heard her voice.

He quickly put aside his distractions and said in a deep voice: "The criminal investigation vehicle should be bulletproof glass, right? Now, raise the left window, and then everyone moves to the right, do it immediately!"

"Okay, I got it. Su Yunhan nodded.

For Zhao Qian, she has no doubts.

"Did you hear it, hurry up!" Su Yunhan ordered.

He was the vice-captain and the commander of the car.

The crowd immediately complied with it, and acted in good measure.

"This Zhao Qian, is it your boyfriend?" Lao Qin glanced at Su Yunhan's mobile phone just now, and naturally recognized this name, and said suspiciously, "He is also a policeman?

"He's not a police officer...... However, he has great powers!" The corners of Su Yun's lips curled, as if she had rekindled hope, and she suddenly radiated.

"Vast supernatural powers?" Lao Qin wondered, is this word used to describe his boyfriend?

"Zhao Qian, it's all done. ”

After doing all this neatly, Su Yunhan said in the police channel.

"Hold your head, squat as hard as you can, it's coming!"

As soon as Zhao Qian's words were finished, a muffled sound sounded.

Boom!

Plop plop!

On the left side of the criminal investigation vehicle, the sound of countless rains hitting the pipa sounded continuously.

Everyone held their heads, not knowing what was happening, but vaguely felt the light shining through.

"It's time to open the window. ”

Zhao Qian's voice sounded.

Open the window and let in the air!

The four of them gasped, breathing in the fresh air hungrily, bursting into tears.

Only then did they realize how precious air is!

For the rest of the people, the unfamiliar name "Zhao Qian" is like a savior!

Lao Qin turned his head and glanced through the car window, his face full of surprise.

"I'll see...... That's at least 30 meters! How does this get through?"

"He always has a way. Su Yunhan smiled, "I said it, he has great powers!"
