"This potion ...... What is it?" After a moment's hesitation, Zhao Qian asked again.

The "rapid growth" in front of me is even somewhat similar to the dropping marrow! But the dropping marrow is only a catalytic mechanical spores, but this kind of agent is effective against mechanical plants, and the applicability is wider and more terrifying!

"I call it 'fireworks'!" said the Great Mechanic triumphantly, "for a moment brilliant, and then burn out." ”

"Didn't you want you to study the 'acupuncture points'?" Zhao Qian touched his nose and wondered, "How did you study this 'firework'?"

He was suspicious.

"Hmph!" Speaking of this, the Great Mechanic's voice was raised, and his tone was a little resentful, "Acupuncture points? Do you know how big the total area of human skin is? A full two square meters! And the skin area of a mechanical beast is tens or even nearly a hundred times that of a human being! Testing the acupuncture points of a mechanical beast is like looking for a needle in a haystack!"

"Oh, is that so?" Zhao Qian's face was embarrassed, he really didn't expect this stubble.

"Because the giant beast is too big, I tried smaller eggs, and inadvertently stimulated the seeds of the mechanical plant with electric currents...... "I found that the mixture of dozens of catalysts, auxins and nutrient solutions, supplemented by electric stimulation, can accelerate the growth of mechanical plants, and complete the years of life in an instant!"

"Sounds interesting. Thinking back to the crazy growth of the black thorn vine, Zhao Qian was also secretly frightened.

He froze and said with a puzzled expression: "However, what's the use of this? The mechanical plants spawned by fireworks will grow in an instant, and they will also be annihilated in an instant, and they will not bear fruit or gain anything...... Also, it seems to empty the earth in an instant, leaving the whole land dry and barren. ”

As he spoke, Zhao Qian grabbed a piece of dry and hard mud and twisted it in his hand.

"What's the use?" the Great Mechanic snorted, as if he had been greatly insulted, "Don't you know? Mechanical plants are not all good, many mechanical plants are 'meat eaters', they can slaughter the Beastmaster, and even hunt the Beastmaster!"

"Oh?" Zhao Qian's eyes lit up.

He was very alert, and immediately understood what the Great Arm meant.

"Fireworks can be used as traps or weapons with specific seeds!" "Da Yan's hand is like a river, and he said in a deep voice, "Moreover, it is a weapon with extremely considerable lethality, huge power, high explosive power, and can even destroy the beast king in an instant!"

"However, more experiments are needed...... the corners of Zhao Qian's lips curled slightly, and he was a little eager to try.

Just do it!

In the afternoon alone, he opened several more laboratories.

......

A week later.

Laboratory Thirteen.

The godkiller stood, holding a metal orb in his hand, sometimes throwing it upwards and catching it immediately.

Knock! Knock!

On the opposite side of the mecha, a roe deer kept hitting the alloy iron cage, its claws and fangs pulling long scratches on the cage post, vicious and tyrannical, ready to pounce.

Not far away, Su Yunhan's martial arts song stood like a mountain, making a vigilant posture.

Of course, she was just a spectator.

"Zhao Qian, isn't it too extravagant to experiment with a beastmaster?" Su Yunhan hesitated for a while, then asked, "Also, what is the 'wonder' ......you are talking about?"

"Without the Beastmaster, how can you test the true power of 'it'? As for the spectacle, you can see it right away!" Zhao Qian smiled and said in a deep voice, "Yun Han, let's start!"

"Hmm!" Su Yunhan nodded, and reminded, "Be careful, don't be too careless......

"Rest assured. Zhao Qian's demeanor was calm.

Click!

Su Yunhan controlled it remotely, and the cage door slowly opened.

Howl!

The decumber escaped, his eyes flushed red, and he immediately launched a fierce attack.

With a terrible howl, its four claws took turns to step on the ground, and its momentum climbed all the way, and the four corners of its head hit the void and produced a roaring sound, which was its mechanical beast skill - "Destroy the Four Poles"!

The giant beast collided, and the sky collapsed!

"It's a good time!" Zhao Qian smiled faintly, and made a god-killing movement, and a metal ball was thrown steadily.

Boom!

In mid-air, the metal ball arced and exploded.

A deep black frenzied spread!

The sphere exploded, countless steel thorns and branches grew, and the vines became entangled into a huge sphere, rolling continuously on the ground, like a rolling stone falling from the sky, and the momentum went straight to the deer!

This mass of metal spheres has a strange charm of "growing when you see the wind", just a few breaths, and the volume is already on par with the deer!

Howl!

Seeing this, it seemed that he had encountered a natural enemy, his body trembled violently, and his four claws fell to the ground, and he was actually ready to flee in the wilderness.

But it's late!

The sphere smashed on the body of the deer, and countless black branches bloomed, penetrating deeply into its body, directly extracting its nutrients, frantically encroaching, and swallowing for a long time!

In just a moment, the body of the deer was shriveled and emaciated like a mummy, turning into a dried corpse.

"Huh?" Su Yunhan's eyes widened, his expression was dull, and he couldn't speak for a long time.

In front of him, there was a beast king, and he was killed in an instant, and there was no room to fight back!

"Wait," Su Yunhan thought of something and asked tentatively, "is this...... Dragon hunting tumbleweed?"

"Oh?" it was Zhao Qian's turn to be surprised, "Yun Han, do you still know this?"

"I've seen some documentaries. Su Yunhan nodded, "Dragon hunting tumbleweed is a carnivorous plant, and it will take the initiative to attack, sneak attack and even directly hunt giant beasts such as dragons! Zhao Qian, are you going to use the Dragon Hunting Tumbleweed as a weapon?"

"Used as a weapon?" this statement is not accurate," Zhao Qian smiled and said meaningfully, "It should be said that this dragon hunting wind tumbleweed will be one of the treasures in my arsenal......

"What?" Su Yunhan was startled, and immediately understood the meaning of Zhao Qian's words.

What he meant was to make a plant arsenal that resembled an "arsenal"!

In the cockpit, Zhao Qian rubbed his chin and fell into deep thought.

He saw that this plant weapon also had a big advantage! The mechanical plant has no intelligence, it can only attack the mechanical beast, but it ignores the mecha! And this advantage allows the plant weapon to carry out precise strikes without accidentally injuring others.

......

Mecha workshop.

The transport mecha came and went, like an assembly line, one after the other, and the river was endless.

The person in charge of the handover was still the mustache of the Demon Capital Logistics, with a smile on the corner of his mouth and a flattering face.

This time, Zhao Qian was not trading mechanical beasts, but the seeds of mechanical plants.

After all, while mechanical beasts are rare, the seeds of many mechanical plants are even rarer, and even priceless.

"Mr. Zhao, do you need anything else? As long as you can get it, it's dragon liver and phoenix gall, and I'll get it for you. The mustache patted his chest, looking like he was swearing.

"What I want, isn't it written on the order form?" Zhao Qian pursed his lips and said with a smile, "Hurry up and get me the rest of the things." ”

"Understood!" the mustache nodded again and again, and then complained, "But, Mr. Zhao, you also have to be considerate of us, there are a few types of seeds that are really difficult to get...... For example, this 'burrowing grass' is very good at hiding and hiding, the surface is not much different from ordinary weeds, it only hunts once in a lifetime, and immediately produces seeds after hunting, so that the grass seeds are scattered to the ground. This plant is said to be strong in battle, and it will not hunt creatures below the Beastmaster!"

"I know better than you the characteristics of burrowing grass, so you don't need to teach me. Zhao Qian waved his hand.

"Of course, of course. The mustache smiled and said, "I promise that as soon as I get a few seeds left, I'll send them to you immediately." ”

"I'm waiting for your news. Zhao Qian nodded, "As soon as possible!"

......

Sending away the mustache, Zhao Qian walked back to the production room.

Inside, an assembly line runs in an orderly manner, equipped with a tube of "fireworks", which runs smoothly and orderly. The son of Voodoo has already had several formed assembly lines, and "Fireworks" is only a new assembly line, which is of course not very difficult for Zhao Qian.

Click, click, click!

The robotic arm rises and falls, picking up plant seeds, carrying out "birth" experiments, recording data and leaving images.

Since it is a weapon, it naturally needs a lot of experimental verification to ensure the stability of the weapon.

"However, it's all money......" Zhao Qian secretly felt pain.

Observation room.

The cube was seated, a projection was suspended, Zhao Qian's expression was focused, and the pen was like flying, leaving countless intertwined arcs.

Time passed, and the seemingly chaotic arc gradually took shape, its slender body and smart lines, like a new mecha!

"-Sower!" Zhao Qian wrapped his arms around, nodded, and whispered, "I just don't know, is it a life sower or a death sower?"

"Hurry up and get to work. "The Great Mechanic is urging again.

......

In the handicraft workshop, Zhao Qian buried himself in work.

A month flies by in a flash.

......

Barren mountains behind the workshop.

"Huh?" Su Yunhan leaned forward, his eyes widened, and his face was full of incredulity, "Did he really make a mecha?" So, this mecha ...... Isn't it equivalent to an alternative martial arts?"

She was secretly amazed and stared intently.

Whew, whew!

The wind howls continuously, and under the sun, a mecha rushes like flying, its movements are ever-changing, and countless exquisite moves seem to flow out one by one, which is dizzying.

Sou!

The mecha spun suddenly, stretched out its long arms forward, and a blood-colored thorn shot out from its palm! The thorn was like a swimming dragon, winding for nearly a hundred meters in an instant, piercing a tungsten steel doll.

Click!

The mecha's right arm shook, and sparks flew on the thorn strip, and it was like a jagged tooth, and it effortlessly cut off its head.

"Blood-drinking thorns?" Su Yunhan recognized this plant, and his heart was cold.

Immediately after, the mecha ghost staggered, his palm shook like a ghost, and a round ball flew out, rolled on the ground, and rolled towards a puppet.

Rumble!

Countless branches and leaves are boiling!

The branches and leaves swept and spread, dancing up and down, like a furious giant, frantically shaking the tungsten steel puppet, and in just a few seconds, it had already been torn to shreds, and the iron filings were flying!

"It's ...... People slaughter mimosa?" Su Yunhan recognized this plant again, and felt cold all over his body, and he couldn't move.

"Oh?" among the sowers, Zhao Qian seemed to think and said to himself, "What the mechanical plant chases, it seems to be a smell? In this case, it can also be used to deal with mechas." ”
