Gong Zibai and Lao Niu were both stunned, and at the same time frowned: "What are you making!?"

Su Dong said calmly: "Spirit crossbow, the name is Chaos Fury, isn't the Spirit Martial Department looking for a special weapon to deal with large sea beasts for a while, so I studied this thing." ”

Lao Niu frowned and sighed: "What nonsense, it's true that the Spirit Martial Department needs a new weapon to deal with sea beasts, but your Spirit Crossbow is too exaggerated! It's too big to shoot into the depths of the ocean." ”

Su Dong said with a smile: "Don't forget, the warrior's vision is limited, assuming that the sea beast hides in the depths of the ocean, the warriors can't see it, and it's useless to give them any kind of weapon, although my Chaos Fury is huge, but the range is more than five hundred meters, I think the warrior's visual system can see so far at most." ”

Lao Niu was slightly stunned, Su Dong was right, the sea water will block the soldiers from observing, if you can't see the sea beast, even if the range can reach five thousand meters, there is no way to play an effective role, it takes two steps to kill the sea beast, first, find it, and second, kill it.

The range of 500 meters is not the strongest among the crossbows, but as a special blade for underwater attacks, it is definitely qualified.

It's just that Lao Niu can't figure it out, Su Dong has built the spirit crossbow so huge, the arrow is bound to withstand strong water pressure, and it seems unlikely that it will reach an effective range of five hundred meters.

At this time, Gong confessed and said: "Our pill series pays attention to experiments, and you can know if you can do it or not, Su Dong, since you are so confident in your spirit crossbow, do you dare to let us experiment here?"

"Of course I do, but there is no lake nearby, and even if there is, I am afraid that the depth is not enough, and I am worried. Su Dong said calmly.

Gong Zibai said disapprerovingly: "It's okay, let's enlarge the range is that if you can shoot five thousand meters in the air, you must be able to attack an object of more than three hundred meters in the water, Lao Niu, you throw a high, let Su Dong demonstrate." ”

Niu Kun nodded, looked around, there was a set of bluestone carved tables and chairs in the courtyard of the palace from Bai's house, Lao Niu copied the table of thousands of catties, and said lightly: "I will throw this thing into the air, facing the back mountain, there is no man's land, you don't have to worry about hurting others, if the distance is more than five thousand meters can still be broken this table made of stone, it proves that your crossbow does have the ability to kill large sea beasts." ”

Su Dong nodded, carried the spirit crossbow on his shoulder, put on a good posture, and said, "No problem, this thing is very powerful, in case it hurts someone, I am not responsible." ”

The old cow didn't speak, his thick arms swung back, and then he suddenly exerted his strength, and the stone table weighing more than a thousand catties was really given out by him!

Maybe it's because he is holding his breath in his heart, and the old cow's throwing strength is not small, so that the stone table collapsed with a bang, half in front, half in the back, and the speed was even faster!

Smack~ Su Dong tapped the button, and a set of two-point aiming mechanisms stretched out from the crossbow, this set of mechanisms was originally hidden inside the crossbow, borrowing from the structure of the optical sight in the previous life, Lao Niu and Gong Zibai had never seen it, and they were a little surprised.

"Hurry! It's almost over the range of five thousand meters!" Phantom Rain shouted a little nervously.

Su Dong is still silent, he is waiting for a key intersection!

When the stone table that was broken in two flew out about seven thousand meters, Su Dong pressed the mechanism.

Whoosh~ The sound of the bowstring chirping is extremely harsh, and the arrows up to one meter and two long burst out!

At this time, the two halves of the stone table had turned into two small black dots in the air, and I saw a black light shot out of Su Dong's spirit crossbow roaring and chasing after him, hitting the first target!

Boom~ What a strange arrow, when it hit the stone table, it immediately shattered! Shattered into thousands of sharp metal spikes of different sizes! Like a scattered bullet, the attack area is also spreading rapidly!

Half of the stone table was blown to pieces at that time, and those metal spikes still did not stagnate, and continued to attack the second target, and the remaining half of the stone table was also blown to pieces!

Explosion, what an explosion!

Su Dong's arrows will explode when they hit obstacles! This is probably the first crossbow in the history of the Divine Domain that can explode.

Lao Niu rubbed his eyes unconfidently, and Gong Zibai's face was more and more surprised.

"It's so powerful! This thing can not only kill sea beasts, but even if it is used for engineering, it can be a generation of big killers!" Gong Zibai said excitedly.

Lao Niu turned his head and asked with some disbelief: "The power is very strong, how can you ensure that the arrow will not deviate from the target under the water?"

"There are four stabilizer wings, and at least the first 200 meters are straight lines. Su Dong said.

"Why did the arrows explode?" asked the old cow again.

"Secret. ”

"Is the aiming mechanism accurate?"

"Precisely. ”

"What principle?"

"Secret. ”

Lao Niu and Gong confessed to asking Su Dong a lot of secrets, but Su Dong did not answer any questions related to the core of the crossbow, as the reincarnation of an earthling, Su Dong's awareness of intellectual property rights is still very strong.

The discussion gradually became hot, Lao Niu and Gong confessed that they were very excited, and it had been proved that the oversized spirit crossbow Chaos Fury designed by Su Dong was definitely a new weapon with powerful lethality!

The bowstring has been repeatedly blessed with the technique of ice casting to reach the limit of metal toughness, and the bullet is very terrifying, and can shoot heavy arrows over a distance of more than ten kilometers.

The arrows are made from a fusion of more than a dozen metals, which are hard and brittle, and will shatter immediately when they come into contact with a hard object.

You know, this kind of fragmentation can occur at high speed, and thousands of metal spikes are shot in all directions, and the lethality is no worse than that of artillery shells!

Such an arrow shot at the sea beast, as if it had been hit by thousands of arrows at once, tearing a bloody hole on its body, even a large sea beast could hardly be spared.

Gong Zibai laughed and said, "How about Lao Niu? I just said that Su Dong Xiaoyou still has real skills, this spirit crossbow should meet the requirements of your spirit martial arts department, right?"

Lao Niu nodded heavily and said: "Very powerful spirit crossbow, but this thing is too vicious, using the arrow breaking technique to cause large-scale damage, if it falls into the hands of bad people, it is not a good thing." ”

Gong Zibai nodded slightly, Lao Niu's worry was not superfluous, this new type of spirit crossbow made by Su Dong was indeed terrifying, after all, the warriors were all spirit warriors, and they were accompanied by spiritual power when attacking, if thousands of such spirit crossbows were aimed at which god of war, it would be difficult to beat the dignified god of war down.

After thinking about it for a while, Gong confessed: "Otherwise, buy a batch in the name of the academy, and then only rent but not sell, and lend it to the students when they want to use it, and take it back when they run out." ”

Lao Niu nodded lightly and said, "Okay, I'm going to take the sample back and discuss it." ”

After hearing this, Phantom Yu frowned and said to Su Dong: "If you rent it, won't the sales go up, will it affect the income, right?"

Su Dong said with a smile: "The academy wants to rent to those students, why don't I rent it to the academy?" Originally, I planned to build some casually, not to make the best, but to make the fastest speed, and when these crossbows are broken, they will come to me to repair them, and they can make more money." ”

"Now if I rent it, I can slowly build a batch of high-quality products, no matter how long I rent it, this batch of crossbows is still mine, but the money has been earned by me, how can it be said that it is a bad thing. ”

Phantom Yu was speechless for a moment, Su Dong was almost counted into the bones, assuming that it was sold, he would make it in large quantities, and then sell it to others to be new if it was broken, and if he rented it, Su Dong would make high-quality products, and he rented and rented this batch of crossbows or Su Dong's, and made money for arrows and rent!

"I think you're probably darker than Huang Buren now!" Phantom Yu figured out Su Dong's strategy and said in a deep voice.

...... Su Dong didn't expect that Lao Niu was actually the director of the Lingwu Department, he was a vigorous and resolute person, and he put down the order the next day, and rented a hundred sets of spirit crossbows from Su Dong in the name of the academy, plus two thousand arrows, and the income was withdrawn according to the standard of the trading center, and Su Dong took ninety percent.

The rent of the spirit crossbow is one white spirit crystal per week, and the arrow is five white spirit crystals, counting up, if the business is good, Su Dong can get about two or three hundred white spirit crystals from the academy every week, and if the amount is increased in the future, the income will increase.

This is almost a business without capital, the raw materials are all left by the ice god, Su Dong only needs to spend a little time to build the crossbow, and from then on, he can collect rent for many years, Su Dong feels that he is starting to feel a little chartered.

...... West.

This sea area is where the academy took over the task of cleaning up the sea beasts.

The fourth group of warriors from the Ask Academy came here, and the task was to shoot as many sea beasts as possible, and each large sea beast was rewarded with a white spirit crystal, three medium-sized ones, and ten small ones.

Among all the tasks in the Ask Academy, this sea beast task is only average, but fortunately, there are many sea beasts, and you can get good points by staying at the beach for a week.

It's a pity that the sea beast is too cunning, living in the sea, and the first three groups of warriors who came here didn't get much benefit, so that this time the total number of people was only thirty, which was a big reduction from before.

The iron-hulled ship sailed out to sea, and the warriors stood on the deck looking for their targets, some with spears, hoping to use their spiritual power to pierce the spears into the water to kill sea beasts, and some with ordinary crossbows, and even those who were ready to use bombs, in short, the warriors prepared various means in exchange for points.

Only one of the warriors rented Su Dong's crossbow, his name was Wei Ying, he was bitten on the thigh by a sea beast when he came last time, and this time it was not so much to earn points as to take revenge.

Su Dong's big spirit crossbow is arrogant enough, its name is Chaos Fury, and it is domineering enough! Wei Ying didn't care if it was useful or not, so he immediately rented a set and bought another twenty arrows.

When Wei Ying took out this Chaos Fury, he was inevitably ridiculed by the students, because Su Dong was a pragmatist, and he only wanted to make things strong and durable, and he didn't care whether they looked good or not.

The crossbow was a big black lump, and there was not even a decorative pattern on it, and the shape was weird, and it was really ugly compared to the spirit soldiers made by others.

"It's a big sea beast!" shouted a warrior on the left deck.

Wei Ying was stunned suddenly, and ran over with a huge and incomparably chaotic rage, pulling out of the stance...
