After Guo Ran finished speaking, a giant crossbow appeared on the space ring, which was different from ordinary bows and crossbows, and the bow arm at the front end of this crossbow was actually straight.

On the bow arm is a golden bowstring, and at both ends of the bow arm, there are two round rollers, and the bowstring is wrapped horizontally and vertically around the bow arm, which makes people confused.

The length of the entire Great Fury is seven feet, which is similar to the height of ordinary people, and the crossbow body is all made of refined steel, just looking at the posture, the weight of this crossbow is very amazing.

Guo Ran took out the huge bow and crossbow, with a smug face, he originally wanted to put on a few very awesome postures, but the giant crossbow was too heavy and could only be placed on the ground.

"Ahem, that boss, my newly designed crossbow is called Po Xu, you can help me shoot an arrow" Guo Ran said with some embarrassment.

Longchen couldn't help but laugh and said, "No, you can't even hold the crossbow you made, how can you fight the enemy? Can't you design it lighter?"

Guo Ran said with a bitter face: "I also want to design it lighter, but in order to increase the power, the strength of the crossbow body must be achieved, otherwise it will not achieve the expected effect at all."

"Gotta try your crossbow"

Longchen stretched out his hand to pick up the giant crossbow, and sank into his hand, no wonder Guo Ran, who was already in the Yi Muscle Realm, couldn't hold it, this giant crossbow actually weighed seventy or eighty thousand catties.

"Good guy, it's really heavy enough, don't let me down with the power" The dragon dust was upside down, although it was nothing to him, but for the average Yijin Realm powerhouse, he couldn't pick it up at all.

"Don't worry, boss, even Cangming's predecessors are full of praise for my invention," Guo Ran said a little proudly.

"Cangming's predecessors have seen this crossbow?"

"But isn't it, he still praises me," Guo Ran said with a smug face.

"What did he say?"

"His old man said, I pulled the calf well, hey, boss, don't despise me, Cangming's predecessor is the first caster master of the other courtyard, it is not easy to get his appreciation" Seeing the contempt on Long Chen's face, Guo Ran said a little unconvinced.

"This is not bad, Cangming's predecessors are arrogant, and they really don't praise people easily, and it can be said that you are a kind of affirmation of you" Longchen nodded.

"Of course, when I saw it to Cangming's seniors at the beginning, the seniors praised me, said that the bowstring was not good, and gave me a few bowstrings, hehe, this made my broken void more powerful" Guo Ran said excitedly.

The bowstrings that Cangming gave him were all made by himself from the silk of Mithril, which is a very soft metal, but amazingly tough, and it is best to use it to make bowstrings.

But Mithril is an extremely precious metal, Guo Ran is not qualified to get it, and even if he does, with his half-baked craftsmanship, he can't process it.

Therefore, getting the bowstring given by Cangming is not only a kind of love, but also an affirmation of him.

I didn't expect Cangming to be so optimistic about this crossbow, but Longchen wanted to see what was so strange about this crossbow.

Reaching out and pulling the crossbow string, with the force of the dragon dust, the two rollers on the crossbow arm rotated slightly, and the originally messy bowstring began to slowly collapse.

"Good fellow, you're very ingenious."

Longchen could see that Guo Ran used an extremely ingenious technique to convert the power through the roller, and it was much easier to pull.

This makes it easy to pull the bowstring, and when the bowstring is released, the roller will fall back in an instant, making the bowstring even more powerful, which is a very clever design.

"Hehe, the last time the boss was assigned to the Rocky Wasteland, he told me that my talent is average, and if I don't find another way, I can only work for the rest of my life.

I thought about it later, what the boss said must be true, people can't always think of hanging themselves from a tree with a crooked neck, they have to find a few more to try.

No, I'm obsessed with tricks, and even though I'm all beginner-level, I really like this thing, and sometimes I dream that I'm fiddling with it.

This battle has given me a taste of sweetness, so I swear that I will be a great craftsman in the future!" Guo Ran said with confidence on his face.

I didn't expect Guo Ran to have such a big revenge, thinking of the previous teasing, Longchen was a little embarrassed.

"Sorry bro, I shouldn't have mocked you"

Guo Ran laughed and said, "What did the boss say, I know you were joking with me"

Dragondust: "No, I'm serious"

Guo Ran: "......"

Dragondust didn't continue to joke, and pulled the bowstring backwards hard, to the shock of Longdust, even with the help of rollers, it still takes a lot of force to pull to the back.

"Click"

The crossbow string was stuck on the card slot, and the bow arm was already like a full moon, looking at the tight bowstring and bow arm, Longchen himself felt a tingling scalp.

How terrifying an arrow shot with such a force is that it is almost life-threatening.

"Guo Ran, this giant crossbow, you can't use it for the time being, you don't have the strength of 200,000 catties, don't want to pull the bowstring full" Long Chen said with some concern.

Guo Ran said with a bitter face: "This is also where I am most distressed, my spiritual root is average, my body is average, and my soul is also average, and together it is very ordinary."

Now that I have made a super awesome void-breaking crossbow, I originally thought that I could kill one or two derivators and achieve the hegemony of the king, but ...... I can't even take it, it's really a great life of grievance!"

"Can you kill the Derivator?" Longchen was taken aback.

Guo Ran said with great confidence: "It's just a prototype now, in the experimental stage, but I believe that once I make it perfect day by day, I can definitely kill the Derivator."

"Boss, I'll bring you the crossbow arrows"

After Guo Ran finished speaking, he went to the cave and came out with a crossbow arrow, and Longchen took a closer look, where is this crossbow arrow, it is clearly a short spear.

The short spear is six feet long, and the thickness of a duck egg, seeing that Guo Ran is carrying it out, you know that this thing is also a heavy guy.

Sure enough, when I weighed it in my hand, the good guy definitely had more than 10,000 catties, and the crossbow arrows were covered with dense small pits.

Looking at these pits, Long Chen couldn't help but admire: "Guo Ran, you are indeed a genius"

"Boss, do you know what these pits are for?" Guo Ran was also taken aback.

"If I'm not mistaken, these pits are used to reduce air resistance and counteract the sound left by air friction," said Dragondust.

It is a physical principle to know that when something moves at high speed, it will squeeze the space and produce a sonic boom.

The body of the crossbow arrow is covered with pits, which can not only cancel out the sound, but also reduce the friction with the air.

Just ask such a powerful crossbow arrow, fly silently, and when you notice it, the crossbow arrow has already been added.

"The boss is the boss, I have been thinking about it for a long time, and I have experimented for a long time before I came to the conclusion, boss, you can see through it at a glance" Guo Ran couldn't help but say with a look of admiration.

"Okay, let's two stop bragging, let's go out and try our might," Longchen said.

After speaking, the two of them went out of the courtyard and found a hill, which was about a dozen zhang high and was a stone mountain.

"That's it"

Longchen held a giant crossbow in his hand, aiming at the hill ten miles away, and hooked a leaf spring in his right hand.

The crossbow bolt flew forward like a bolt of lightning, and at the moment when the crossbow arrow flew out, Longchen Dan felt a strong turn on the giant crossbow, and he couldn't help but take more than a dozen steps backwards.

"Boom"

There was a bang from the hill in the distance, and the whole hill was shattered by the terrifying force, and the sky was filled with smoke and dust.

"Good guys"

Longchen and Guo Ran were stunned to see all this, and Guo Ran was also shocked beyond measure.

Although it was designed by Guo Ran himself, Guo Ran has never been able to launch alone, and today is the first time to see the effect.

There is no explosive device on the crossbow arrow, it is all based on the inertia of the crossbow arrow, and it is simply terrifying to blow a stone mountain to the ground.

The most frightening thing is that when the crossbow arrow flew out, there was no life at all.

"Hidden Arrows Hurt"

Long Chen and Guo Ran glanced at each other, a trace of obscenity flashed in their eyes, and they smiled, and even said these four words at the same time.

After the two finished speaking, they couldn't help laughing, Guo Ran has this big killing weapon, and the lethality will be terrifying.

But smiling and smiling, Guo Ran couldn't laugh anymore, no matter how awesome things were, there was no point in using them.

Although dragon dust can be used, dragon dust has always been head-to-head, rushing to the front line, and there is no chance to use this thing.

Longchen patted Guo Ran on the shoulder and said, "Don't worry, this matter is on me, I'll help you get it."

"Really?" Guo Ran was overjoyed.

"Isn't this nonsense, when have I fooled you?" said Long Chen, angrily.

"But there is one thing I need to make clear to you, as long as you keep your Dao heart firm, I can guarantee that you will have no bottlenecks in your promotion for the rest of your life."

"How is this possible?" Guo Ran said in disbelief.

There is no bottleneck in a lifetime, even if it is a god, it may not be able to do it!

"As long as you can ensure that your Dao heart is firm, I can do it," Long Chen said very seriously.

"Boss, what is the Dao Heart?" asked Guo Ran.

"The so-called Dao heart is a kind of faith, you firmly believe in a truth, and it will never change.

But everyone's beliefs are different, for example, your current belief is your invention and creation, and you believe that with your wisdom, you can overcome any difficulties and become a craftsman admired by outsiders.

This is your Dao heart, as long as your Dao heart is firm and unshakable, I can use pills to help you improve your realm.

But once something goes wrong with your Dao mind, and you feel confused or confused about your own choice, your cultivation will stop forever," Long Chen's very serious Dao said.

Everyone's Dao heart is different, some people believe in their own inheritance, some people believe in their own exercises, some people believe in their own bloodline, and some people believe that they are the pride of the sky.

No matter what kind of Dao mind it is, it has to go through endless training, and many people become less and less confident in the process of training, and finally they don't know what they should believe, and they lose their Taoist faith.

Even if the Dao Heart is strong, after receiving a great blow, the Dao Heart cannot remain flawless and unblemished, and still loses the opportunity to be promoted to the strongest.

And Guo Ran's Dao heart is very dangerous, because his self-confidence comes from himself, once his own wisdom is hollowed out, his thinking will dry up, and he will fall into confusion, and once he is confused, it will be over.

Because his foundation was all piled up with pills, he didn't have the opportunity to choose the Dao Heart again, to put it bluntly, he would become a benevolent if he didn't succeed.

"Boss, I will definitely become a craftsman," Guo Ran said with a deep breath.

Longchen nodded, since Guo Ran had chosen, then Longchen would do his best to help him, as for how far he could go, it was up to him.

took a look at Guo Ran's new invention, which made Longchen have to sigh, Guo Ran is a genius, and there are all kinds of weird things.

The next day, when Longchen was about to go and find something to do, Elder Sun returned. For mobile phone users, please visit http://m.piaotian.net
