In the tide of applause, the Four Elephants Competition came to a successful conclusion.

The flow of people slowly receded, and everyone looked unsatisfied, discussing with their companions in a low voice, mentioning the name "Zhao Qian" from time to time, and praising them in their words.

The villain, the butcher, the banshee, the three sets of mecha armaments all left a deep impression on them, which can be called "unforgettable"!

Zhao Qian was full of smiles and secretly proud.

He knew that his name should leave a huge influence in the army, and the benefits would gradually become apparent in the future.

After the Four Elephants Competition, Zhao Qianwan refused everyone's retention and said goodbye soon.

Regression.

Mecha workshop.

At the gate, Zhao Qian tilted his head, wrapped his arms, and stared at the three signs hanging high in the corridor for a long time.

After a long time, he nodded with satisfaction and said to himself: "This thing is more than any 'golden sign' ox fork......

Three gold-edged brands, from left to right, are "Imperial Machinery Equipment Department Specially Invited Cooperation Object", "Imperial Machinery Research Institute Cooperative Enterprise", and there are four big characters in Huo Qichi's handwriting - "Technical Pillar".

These three brands are full of weight!

Zhao Qian believes that no matter who wants to come to the mecha workshop to play tricks, the first time they see these three brands, they will also weigh their own catties.

The biggest gain of this trip, in addition to the first mountain copper, is these three brands.

"What are you looking at? If you look at it again, you can still see a flower?" the big man urged, and his tone couldn't wait, "Hurry up and work!"

"Got it. Zhao Qian nodded, and said half-grumblingly, "What is in that piece of Shoushan copper? Is there any other ore? But what ore can be more precious than Shoushan copper?"

He was puzzled.

After scanning the Shoushan Copper, Zhao Qian vaguely felt that the reaction of the Great Yan Mechanic was very strange, and his tone was fanatical.

It seems that there are still some rare things hidden in the copper of the first mountain!

"Don't ask, hurry up and do it! Isn't it more direct to see with your eyes?"

"Good. Zhao Qian's face was helpless, and he said, "Dayan, protective clothing!"

"Got it. ”

The ghostly light of the Great Yan Weapon Arm flowed, starting from the elbow, wisps of silver stretched out, gradually covering Zhao Qian's whole body, turning into a set of strict protective clothing.

"Tsk, this guy, I don't know how many secrets are still hidden......" Zhao Qian looked down, secretly surprised.

The protective clothing made by the Dayan Robot can not only isolate low temperatures, but also have an automatic temperature control system and an air exchange system, and can even eliminate sweat, making the whole body uncomfortable.

Zhao Qian couldn't figure out the mechanism at all.

"Forget it, it's important to get down to business......" He shook his head, rejuvenated his muscles, picked up a hammer from the side of the aisle, and walked into the cryogenic chamber.

Cryogenic chamber.

The blue mist is thick, the temperature is already minus 200 degrees, and the first mountain copper is displayed in the center of the room, the surface is covered with a thin layer of frost, and the cold air is fierce.

"Let's start!" Zhao Qian took a deep breath and picked up the sledgehammer.

Clang!

Clang!

Clang!

The sound of hammering resounded, accompanied by the "encouragement" of the big man, and it reverberated endlessly.

"Didn't you eat?

"Are you a man? It's only been five minutes, and you want to rest?"

"Hurry, hurry!"

......

Zhao Qian was so tired that he couldn't help but complain: "Why don't you use a cutting machine......?

"Press?" said in a disdainful tone, "You know what, what to do if you hurt it?"

"It?" Zhao Qian was stunned when he heard this.

The tone of the Great Mechanic is like describing some kind of life!

"Stop thinking nonsense and keep working. ”

Seeing Zhao Qian's hesitation, the big man gave an order.

Zhao Qian pursed his lips, so he had to vent his anger on the Shoushan copper in front of him, picked up the sledgehammer, and struck hard.

He didn't expect that this knock would be a full six hours!

"Whoop, whoop......"

Zhao Qian gasped deeply, feeling that his whole body was about to fall apart, his back hurt, and his heart was beating like a drum.

Fortunately, he has the blue moon mark milk to refine his physique, and his physical fitness is far beyond ordinary people, otherwise he would have fallen a long time ago.

Clang!

Clang!

Clang!

After striking iron for so long, he also had experience as a blacksmith, adjusting his breathing, and each hammer maintained an even speed, rhythmically striking again and again.

Click!

When Zhao Qian was almost numb, a crisp sound sounded, and a crack appeared on the copper of the first mountain.

This crisp sound is tantamount to a heavenly sound!

"Metal fatigue! This is metal fatigue!" The light of the Great Yan Mechanic floated, and he said in a continuous voice, "Hurry up, there is only one last step left in the long march, and then work harder!"

"Know!" Zhao Qian smiled, and his spirits were also lifted.

"Drink!"

"Drink!"

"Drink!"

With a loud shout, he squeezed the hammer fiercely, hammer after hammer, and smashed down fiercely.

Time passed, and the cracks grew.

Clang!

Eventually, the first mountain copper shattered from it and split in two.

"Huh, what is this?"

Zhao Qian looked fixedly, his gaze suddenly straightened, staring at half of the first mountain copper, stunned.

He had had made countless guesses in advance, and even suspected that a stone monkey would pop out of it, but he didn't expect the situation in front of him!

A sapling?

This sapling is no ordinary plant, and unlike silicon-based plants, it has only four leaves, but it is crystal clear, like jade. The shape of the sapling is completely symmetrical, each leaf seems to be carved by the gods, and the veins of the leaves are perfect, and it is naturally formed!

"It's so beautiful......" Zhao Qian narrowed his eyes and couldn't help but sigh.

"Don't be stunned!" urged the Great Mechanic, "as soon as it comes into contact with the air, it will wake up from its dormancy and draw nourishment from its roots......!

"Absorb nutrients, suffer heavy losses?" Zhao Qian didn't know.

He slowed down, and saw the roots of the saplings emerging one by one, like countless entangled white dragons, piercing into the Shoushan copper on one side.

In just a moment, the roots of the sapling absorbed nutrients, and the color of the first mountain copper gradually turned black, turning into ordinary soil!

In less than five minutes, a fist-sized Shoushan copper turned to dust.

That's all Shoushan copper, the priceless Shoushan copper!

"-Hiss!" Zhao Qian gasped, not daring to slack off, and hurriedly stepped forward to grab it carefully.

The small tree seemed to have spirituality, and in an instant, countless roots and whiskers were entangled and rolled up, and they were rolled up by the Great Robot.

"Hmm, Dayan, are you okay?" Zhao Qian was shocked and hurriedly said.

"Don't worry, it can't help me!" "Also, this guy loves to eat metal, and he won't refuse to come! Don't you have a scrapped hoe? Use it to feed it first, it should last for a few days." ”

"Know!" Zhao Qian grabbed the small tree and immediately rushed out of the door.

......

"Ho He, your historical mission has been completed, sorry ......"

Zhao Qian stretched out his hands and put the sapling on the hoe.

Ka!

The sapling is like a greedy little beast, its roots churning, digging deep into the steel, sucking frantically and sucking for nourishment.

In just a moment, with the small tree as the center of the circle, the steel body of the hoe was eroded little by little, and slowly turned into dust!

"Dayan, what is this?" Zhao Qian secretly palpitated, and couldn't help but ask again.

"It's a special silicon-based plant," Daiyan Gunjurate, "Mechanical Sacred Tree—Tsubaki!"

"Da Chun?" Zhao Qian touched his nose, looking dazed.

"Boy, you're in luck!" Da Yanji's hand flickered, obviously excited, "The value of this big tree is enough to support an imperial giant!"

"What?, a wealthy family?" Zhao Qian's eyes widened, and he couldn't help but turn his head to look at Da Chun, "It, what's the use of it?"

"Look at it......"

At this time, the sun shines down, and the four leaves of the Tsubaki rise one after another to welcome the light. In the leaves, the sunlight is repeatedly refracted and is brilliant, dazzling!

"This is Tsubaki's photosynthesis," the big man paused, "but it's not carbon dioxide ...... it's spitting."

"Not carbon dioxide?" Zhao Qian was stunned.

The branches and leaves of the big tsubaki are swaying, and red bubbles are emerging, floating in the air, colorful and swaying.

These bubbles are vaguely transparent, and there are countless electric arcs swimming on their surfaces, which are magnificent and blurry, and quite beautiful.

"What is this?" Zhao Qian's eyes were confused, and he couldn't help but stretch out his palm, wanting to touch this balloon.

"Hurry up!" said sharply, "If you want to keep your hand, stop it!"

"What's wrong?" Zhao Qian was stunned for a moment, and hurriedly withdrew his hand.

At this moment, a red bubble hit the wall and exploded.

Rumble!

The furious roar echoed, countless arcs surged in all directions, and the tempered glass exploded with a bang, as if a small magnetic storm bomb had been detonated!

"What is this?" Zhao Qian looked stunned and hurriedly retreated.

"This thing, it's called a high-energy charged particle. "Every small charged particle is equivalent to a super battery!" With this large tsubaki, we have inexhaustible high-efficiency energy!"

"High-efficiency energy?" Zhao Qian's eyes moved, and he couldn't help but say, "Used to generate electricity?" or, to make batteries?"

The Great Yan Arm fell silent for a long time before he said disdainfully: "I can only say that ignorance limits your imagination......"

"......" Zhao Qian was depressed.

"Do you know the Razor Engine, what about the Thunder Driving Hand, the Divine Hammer, the Thunderstorm Haze?" the Great Mechanic asked again and again, "This high-energy charged particle can make you turn into a thunder god, drive thunder and lightning, and the means are unlimited!"

"Thor?" Zhao Qian's face was full of surprise, and he also felt a burst of shock when he listened to the unfamiliar but domineering words.

Boom! Boom! Boom!

At this moment, a series of explosions resounded, and even a charged particle was about to penetrate the crack in the window and fly out of the workshop!

"Eh, don't talk about the future, what should I do now?" Zhao Qian hurriedly asked.

"A tree nursery needs to be built to grow the Tsubaki and collect charged particles. "Daiyan Jarate.

"Can't you say it earlier?" Zhao Qian looked depressed, "How can it be too late?"

"Oh, so excited, I forgot. The Great Arm seemed a little embarrassed as well.

"Hurry up, what now?" Zhao Qian hurriedly said.

"It doesn't matter, as long as the air is isolated, the big tsubaki will naturally sleep. "Is there an air pump?"

"I'll get it right away!"
