"Make a liquid nitrogen missile!" Old man Zhang Qiuhan touched his nose, building a missile, or a missile launcher, is not a very difficult thing for old man Zhang Qiuhan.

But the crux of the matter is that Zhang Qiuhan doesn't think a single missile can cause much threat or damage.

A missile is at most that big, and it can hold hundreds of liters of liquid nitrogen in it, can such a missile really produce huge power?

What's even worse is that not counting how many resources and faith divine power is needed for a missile launcher, if you just build a missile, the faith divine power consumed will probably be at least about ten points, even if Zhang Qiuhan smashes all the remaining faith divine power into it, he can't make many missiles and how many missiles come out!

"That's!" Old man Zhang Qiuhan finally threw aside the piece of paper in his hand, what are you kidding, he still uses his magic weapon, the extremely cold jet gun.

So, Zhang Qiuhan found the manager Xotus who was standing in the center of the platform.

In the very center of the entire Molten Heart, there is a platform completely surrounded by a magma river several 10 meters wide, and the entire platform is heart-shaped, which is probably the magma river and platform that the exploration team first discovered, and it is also the origin of the name Molten Heart.

The entire platform is almost independent of the lava, and there is no other way for the player to enter the platform except for a thick chain that spans the ends of the platform and allows the player to enter the platform.

Originally, this platform belonged to the manager Exotus, but after this boss was killed by Zhang Qiuhan, he reverted to his human form, and then stood honestly in the center of the room.

According to the strategy above, the current Xotus is already an NPC that cannot be attacked, and he has only one task, that is, after the player is ready, summon the final boss Ragnaros.

Old man Zhang Qiuhan didn't have anything to prepare, so he directly found the manager Exotus, and after a clean conversation, he summoned Ragnaros.

"Damn! So big! After seeing Ragnaros, Zhang Qiuhan, a well-informed old man, couldn't help but stick out his tongue.

Because the size of this Ragnaros is so huge, it surpasses all the bosses that Zhang Qiuhan has seen before, and almost fills the entire underground space.

"Well, it looks like the old man is going to have a hard fight!" A flame burned between Zhang Qiuhan's eyebrows, and when Zhang Qiuhan sprayed the first stream of liquid nitrogen towards Ragnaros, the entire venue suddenly began to tremble violently.

"What's going on?" Zhang Qiuhan was stunned for a moment, and then he felt a heat under his feet, and a stream of crimson magma instantly erupted from under Zhang Qiuhan's feet, and a damage number of -100 directly appeared on Zhang Qiuhan's head.

"Zhang Lao!!"

"Babble!!"

At this moment, Liu Mengxi, who was watching from a distance, involuntarily covered his mouth. Liu Mengxi thought that this was another personal killing show brought by Zhang Lao, just like before.

But I never expected that Zhang Qiuhan, who was still strong and unparalleled before, was directly killed in seconds at the beginning of the battle at this moment.

"What should I do?" Just when Liu Mengxi was at a loss in her heart, Zhang Muyan, who was controlled by her, suddenly jumped up and broke away from Liu Mengxi's control.

"Zhang Muyan, you're coming back soon!" Liu Mengxi shouted, but unfortunately Zhang Muxi ignored Liu Mengxi at all and rushed directly into the battlefield.

At this time, Ragnaros also discovered Zhang Muyan, an uninvited guest, and he immediately aimed his angry flames at Zhang Muyan, and smashed two fireballs with a flick of his hand.

The speed of these two fireballs was extremely fast, and they were about to smash on Zhang Muxi's body, which made Liu Mengxi involuntarily cover his mouth, for fear of seeing Zhang Muxi being burned to charcoal.

At this moment, Liu Mengxi's eyes widened violently, because when the flames were about to hit Zhang Muxi, Zhang Muxi was actually deformed at this moment.

The whole deformation was quite fast, and before Liu Mengxi could react to what was happening, Zhang Muyan, who was wearing a full Cenarion suit, directly turned into a swift black panther.

The speed of this black panther was extremely fast, and in the blink of an eye, it dodged Ragnaros's fireball, quickly rushed to Zhang Qiuhan's side, and then bit Zhang Qiuhan's neck, ran all the way with it, and killed it from the platform.

In this whole process, Zhang Muyan's movements and body skills were extremely fast, and they were also agile to the extreme, even if Ragnaros kept throwing various fireballs and skills, they were all dodged by Zhang Muyan with his speed and body skills, and finally successfully took Zhang Qiuhan who was unconscious away from the platform.

And as Zhang Qiuhan disappeared into the platform, although Ragnaros was crazy, he had no choice but to roar angrily a few times, and then disappeared into the entire platform, allowing the platform to regain calm.

————————————

"So, I was saved by Mu Yan!!" After Zhang Qiuhan, who woke up from a coma, listened to Liu Mengxi's story, he touched Zhang Muxi's little head with some gratitude and said.

And Zhang Muyan, a little cutie, happily burrowed her head into Zhang Qiuhan's arms and rubbed, really like a little leopard.

"Elder Zhang, aren't you shocked at all? She became a leopard, I saw it with my own eyes, don't you believe it? At this moment, Liu Mengxi was still immersed in the terrible fact that Zhang Muxi had turned into a leopard.

"Haha!" Zhang Qiuhan smiled kindly and said, "The old man is 80 years old, and he has walked on more bridges than you have ever eaten salt, which is nothing surprising!" ”

"But...... But...... But we have to figure out why Mu Yan suddenly became a black panther, otherwise what if Mu Yan is in danger in the future? Liu Mengxi smiled bitterly.

"Oh, there's no need to bother with this question, the old man has already figured out why Mu Yan turned into a black panther!" Zhang Qiuhan said with a smile.

"Why?" Liu Mengxi asked stupidly, she was indeed a little stupid, this Zhang Qiuhan had just gotten up from a coma, and he hadn't seen what had just happened with his own eyes, let alone done any investigation, how did he know why Zhang Muhan had turned into a black panther.

"Child, sometimes you have to think about problems with diffuse divergent thinking on the basis of reasonable assumptions!" Zhang Qiuhan said in an old-fashioned manner, "You see, Mu Yan is now wearing a full set of druid suits, and according to the old man's understanding of the druid profession, in the legends of Western fantasy, the druid is a magical profession that can turn into various animals!" ”

"So the old man is at least 90% sure that in the set of druid suit effect skills worn by Mu Yan, he should have the skill that can transform into a black panther, and Mu Yan should use this skill!"

"My lovely little love, you must have sensed grandpa's danger, so you instinctively used the skills on this set of equipment to save grandpa, right?" Zhang Qiuhan hugged Zhang Muhan high, and the Chinese were full of emotion and love, while Zhang Muhan obediently stretched out her tongue and licked Zhang Qiuhan's palm like a kitten.

"Hmph...... Isn't it just going to turn into a panther...... What's the big deal," Liu Mengxi on the other side said sourly.

Well, Zhang Qiuhan didn't have the heart to appease Liu Mengxi's little daughter's jealous mentality, Zhang Qiuhan now had to figure out how to kill this Ragnaros.

There is no doubt that Agnaros is the ultimate boss and the toughest opponent of all bosses.

Not to mention anything else, the skill of spraying magma from the entire platform alone is a skill that Zhang Qiuhan can't deal with at all.

Because the weight of the extreme cold jet is too heavy, especially when it is filled with liquid nitrogen, the weight is almost 400 catties, although Zhang Qiuhan has strengthened a certain physical value, but as long as he carries this gun, Zhang Qiuhan has no possibility of moving.

And once Zhang Qiuhan can't move, this magma that will erupt from the ground anytime and anywhere can directly devour Zhang Qiuhan.

This couldn't help but make Zhang Qiuhan completely distressed, until his old man remembered the note with the words "liquid nitrogen missile" written on it that he had thrown away.

"Okay, maybe the old man is really stupid, judging from the current situation, there are really only missiles that can deal with Ragnaros......" Zhang Qiuhan touched his nose and pondered.

In fact, Zhang Muyan's panther saving his grandfather's behavior just now also gave Zhang Qiuhan an amazing inspiration and discovery, that is, Ragnaros does not seem to be able to attack enemies outside the platform.

Anyway, at least the magma that ejects from the ground only exists on the platform, and there is no magma ejected from outside the platform, and even the surrounding magma rivers will not spew magma...... These are all what Liu Mengxi told Zhang Qiuhan.

This gave Zhang Qiuhan an astonishing idea, that is, if Zhang Qiuhan stayed outside the platform and attacked Ragnaros, then Ragnaro was proud of the jet of magma flames, would it be useless for himself.

Even said that because Ragnaros couldn't leave the platform, his attack couldn't touch Dao Zhang Qiuhan, Zhang Qiuhan only needed to hide outside the platform to attack, and everything would be fine.

It's a pity that the range of the Extreme Cold Jet Gun can't meet this need, the radius of this platform is about 500 meters, and with the extreme cold Jet Gun's 200-meter limit spray distance, it is absolutely impossible to attack Ragnaros, Zhang Qiuhan must develop a new weapon, a weapon that can accurately hit Ragnaros from 500 meters away.

Like what...... One missile!

"Okay, Zhang Qiuhan had to admit that he was a fool, and what was written on that note was the truth, and this note told Zhang Qiuhan early on that he had to make a liquid nitrogen missile to be able to deal with Ragnaros.

But how to make such a liquid nitrogen weapon, Zhang Qiuhan still had a black eye, and he didn't have a good idea for the time being.

Although missile weapons are not a problem for a talent like Zhang Qiuhan, Zhang Qiuhan himself has seen many missile design drawings.

However, the warheads of these missiles are generally filled with several hundred kilograms of high explosives, and they do not occupy a large area, which can cause a terrifying explosion effect.

But the problem is that the space that can hold hundreds of kilograms of high explosives is at most a few dozen liters of liquid nitrogen, and it costs more than ten or twenty points of faith divine power to create a missile, but it can only carry dozens of liters of liquid nitrogen, which is not a good deal, and the belief divine power is exhausted, and I am afraid that it will not be able to consume one-tenth of Ragnaros's blood bar.

"No, the old man has to develop a completely different missile!"

So, with such an idea, Zhang Qiuhan fell into intense work and design, and one idea after another burst out in Zhang Qiuhan's mind, but one idea after another was rejected by Zhang Qiuhan.

Just when Zhang Qiuhan felt troubled, the phone vibrated and a new chapter was updated.

"Hey...... Let's read the novel! Zhang Qiuhan originally wanted to continue thinking, but there was no better way to think about it, so he could only decide to read the novel first, thinking that he could change his thinking.

"By the way, it seems that there was an event in the group just now that grabbed the throne and had to be managed!" Zhang Qiuhan will remember the time when he swiped the QQ group before the battle, because every time he opened his mobile phone, he could see a large number of readers applying to join the group, which made Mr. Zhang feel a little too busy, so he proposed in the group that he wanted to find a few more administrators to help him.

As a result, I didn't expect that the vicissitudes of the waves, who had not shown up, actually jumped out and came up with a bad idea, saying that whoever can grab the next updated throne, that is, the first chapter after the chapter name, who will be able to become the new administrator.

A group of readers in the group screamed one by one.

However, there are also some readers who say that their network is very bad and will have congenital disadvantages, so after Zhang Qiuhan pondered for a while, he secretly chatted about the ups and downs, and suggested that he should not only give the reward to the first administrator, but also give more readers a chance, it is better to add another 81st place to get the rules of the administrator.

Zhang Qiuhan thinks so, the first place is of course to depend on the speed of the hand, then the 81st place is not the case, it depends on the strategy of the readers, because when it comes to the 70th or so, the readers will not continue to brush, just want to wait for others to brush, and then grab the 81 position themselves, so that a long gap will be formed, only the readers who have really mastered the strategy and tactics can grab the 81st position.

Although Canglan Short did not reply to Zhang Qiuhan, the rules have changed, and the rule that the 81st can also get the administrator has been directly added, so that Zhang Qiuhan understands that this Canglan Short should have seen his own suggestion, but he was too lazy to reply to himself.

"What a rude child!" Zhang Qiuhan shook his head, this turbulence is short, and the quality of life needs to be improved!

"yes, I'd like to see who the 1st and 81st places are!" Thinking of this, the old man Zhang Qiuhan couldn't help but be a little excited, and after clicking on the Chapter 24 Cenarion suit, he immediately looked at the chapter behind the chapter name and said, The number 99 turned out to be a deep stab in Zhang Qiuhan's old eyes.

And when Zhang Qiuhan clicked on it, he found that there were not 99 comments at all, but already had 124 comments, and the chapter on the page of the book said that it could only show 99 at most.

Zhang Qiuhan sighed a few times, and quickly browsed it, and found that the first place was occupied by a reader named zzzzz, a book named Only Reading Sanshao, and then there were a lot of readers behind him who were admiring how this guy's speed was so fast.

And the 81st floor fell into the hands of a night of chaos, this is a name that Zhang Qiuhan is quite familiar with, after all, he often sees it when rewarding.

"Well, isn't it that frequent tipping helps to improve one's strategic and tactical ability?" Zhang Qiuhan touched his nose and felt that he had discovered an amazing social black technology law.

I don't know if it's because the activities of robbing the king consumed most of the readers' energy, and then this chapter is quite rare, when he saw the Cenarion boots, Zhang Qiuhan learned from the reader's original saying, it turns out that this Cenarion is the meaning of the Druid Council, it seems that this set of equipment is quite extraordinary!

And when writing about the career system, Zhang Qiuhan saw many readers speculating that there should be occupations in the science and technology department, or occupations such as repairers and mechanics, Zhang Qiuhan nodded again and again, there should be such a career system, otherwise the human civilization that is vigorously developing science and technology will not become scum.

However, when writing about the starship, there were a lot of names that made Zhang Qiuhan feel inexplicable, such as what Saitama, and what Kakarot, they all seemed to be able to punch the existence of the entire starship, which made Zhang Qiuhan can't help but feel yearning, if there is a chance, Zhang Qiuhan would like to fight against these two to see if the starship he will build in the future can teach them to be human!

"The journey of mankind is the sea of stars!" After that, Zhang Qiuhan suddenly saw this sentence that made his old bones feel blood gushing.

"Yes, the journey of our human race is the sea of stars!" Zhang Qiuhan waved this fist excitedly, like an old child.

"Hey, there's a reader here who thinks the same way I do!" When writing about Zhang Muyan wearing Cenarion boots, a reader's statement quickly resonated with Zhang Qiuhan, in fact, Zhang Qiuhan also thought about why Zhang Muyan was able to wear a druid suit, and finally came to the same conclusion as this reader's statement, Zhang Muyan is too pure, or a pure baby, has not been polluted by humans, maybe such children are the children closest to the profession of druids, and they can wear such equipment without meeting the requirements of the professional level!

After that, there was also a reader named Zui Mo Yiliu, who gave Zhang Qiuhan a detailed science popularization of the worldview, but unfortunately it was too grandiose, Zhang Qiuhan said that he needed to study it carefully to be able to understand the essence of the concept.

In the end, when Zhang Qiuhan saw the passage "There are 4 small words written on it: liquid nitrogen missile", the following chapter said that it completely attracted Zhang Qiuhan's attention.

There are only three chapters here that first attracted Zhang Qiuhan's attention because the name of the reader who spoke was actually Hirano Cui.

Of course, after so many days of understanding, Zhang Qiuhan can be sure that the owner of this name is by no means his own Xiaocui, but a name specially changed by a reader who joined in the fun.

But this sentence left behind by Hirano Cui made Zhang Qiuhan tremble with excitement.

"Actually, it's quite simple to build a missile, anyway, you don't need a detonation system, as long as that balloon is filled with liquid nitrogen and thrown over, the fire element will explode directly!"

This article said that the sentence actually written did not make sense, and there was a typo, but it gave Zhang Qiuhan great inspiration every moment.

Yes, that's right, why bother with the detonation system of the missile, this missile actually doesn't need to be detonated at all, just throw it yourself!

From just now to the present, the reason why Zhang Qiuhan has fallen into a situation of hard thinking is mainly the detonation of the missile, the launch system, and the volume of liquid nitrogen that can be accommodated.

Zhang Qiuhan found that he was actually stuck in a mindset, because Zhang Qiuhan's previous research and manufacturing missiles were basically the kind of ultra-long-range missiles that can bomb thousands of kilometers, so such missiles often require huge propulsion systems, as well as accurate ammunition detonation systems, etc., these systems occupy more than 3/4 of the volume of the missile, and only 1/4 is really used to accommodate ammunition.

And the cost of these propulsion systems and ammunition detonation systems is worth the cost of a dozen Arctic Cold Jet Guns. Although Zhang Qiuhan has been thinking about how to streamline these systems, no matter how streamlined they are, they cannot be substantially optimized.

Until Zhang Qiuhan saw this chapter from Hirano Cui.

Yes, you can directly eliminate all these propulsion systems and ammunition detonation systems!

Anyway, the launch distance you need is only 500 meters, so you can just install a small amount of gunpowder at the bottom like a gun to achieve the effect of jet propulsion, and there is no need to build such a complex propulsion system like manufacturing an ultra-long-range missile for thousands of kilometers.

As for the detonation system...... This is even simpler, the material directly made of the missile shell is made into a hot melted material, as long as such a missile touches Ragnaros, the shell will be immediately melted by the hot temperature of Ragnaros's body, and all the liquid nitrogen in it will be sprayed out, and there is no need for any detonation system at all.

To give a simple example, Zhang Qiuhan had been thinking about how to simplify the Dongfeng Express into a Scud missile, but later Zhang Qiuhan found that there was no need for any missiles at all, you just took a balloon filled with liquid nitrogen and threw it on Ragnaros.

With the help of this chapter, Zhang Qiuhan's long-imprisoned thinking quickly exploded in a short period of time, and in just three minutes, a new liquid nitrogen missile system was produced.

The first is the missile itself, which is simply very simple, the shell is a layer of carbon asbestos shell no more than two or three millimeters thick, which is a new material developed by Mars, which is not only cheap, but also very strong, comparable to the strength of steel, but the price is only 1/20 of steel.

However, this material has a great weakness, that is, it cannot stand the high temperature, as long as the temperature exceeds 80 degrees, it will immediately melt and lose its effect.

This was originally a rather chicken material, but now it is the best material for making liquid nitrogen missiles, and the whole missile is actually a streamlined shell made of this carbon-asbestos, which only needs to be filled with liquid nitrogen, without any additional materials and systems, it is simply simple.

The only complicated point is the launcher, first of all, this launcher has a very long barrel, and Zhang Qiuhan has designed an instantaneous detonation system with a tail, which can fly the missile out by igniting the huge air pressure generated by the combustible.

Of course, in order to prevent the tail of carbon-asbestos from melting under the influence of heat, Zhang Qiuhan added a propulsion piston with a heat-insulating effect in the middle, and the impact of the combustible gas explosion directly hit the propulsion piston, and then the propulsion piston pushed the missile out.

Zhang Qiuhan has calculated that the range of such a rudimentary missile is only about 1 km, and as far as missiles are concerned, this is simply an insult to the word missile.

But there is no doubt that it is enough to deal with Ragnaros.

"Thank you, Tsui Hirano!" Zhang Qiuhan said with a grateful face, "I will remember the great contribution you have made to mankind, if we human beings stand in the distance of the sea of stars in the future, there will definitely be your name on the monument of merit!" ”
