After a moment of stunnedness, Su Yun's red lips pursed, but she was relieved.

The corners of her eyes were slightly raised, and fluorescence flowed in her faint pupils, and she said, "It is indeed a wonderful idea to combine the phantom array and the flying sword to make an invisible flying sword. ”

"Among the powerhouses of the Yudan Realm, this kind of action is not uncommon, using the combination of the Phantom Array and the Flying Sword to turn into the ability of destruction to attack the enemy, but this kind of use can only be used by the strong people of the Yudan Realm and even the Yuan Shen Realm, and the use of the Invisible Flying Sword has never appeared in the battle of the Daoji Realm. ”

Hearing this, Xia Chao smiled and said nothing.

In fact, the initiative of the invisible flying sword has been mentioned more than once in the humane civilization, but only the strong people of the Jiedan Realm can use various formation methods to achieve actual combat effects, and the flying swords used in the ordinary Dao Foundation Realm are rarely assisted by phantom arrays.

And the reason is because of lethality.

The descendants of gods and demons are not extraordinary creatures, their bodies are as hard as iron, and their magic energy is very strong, and they are hard to deal with such creatures, they don't have enough destructive power, and they can't even break through their defenses, so the flying swords that can be used by Dao Ji Realm monks are developing towards their ultimate lethality.

The first criterion for measuring the merits of the so-called flying sword is often its power.

After all, a monk in this realm could only use a mid-level magic array, but with only five hundred runes as the limit, the normal formation diagram lacked even some lethality, so where did the monk have the heart to engrave the phantom array again to add brilliance to it?

However, Xia Chao's nuclear fission flying sword array diagram was different.

Its destructive ability is incomparable, domineering and infinite, with the energy of the mid-level array, it can injure the third-order creatures, and the power is the top existence in the mid-level array, there is no need to worry about the lack of lethality, and there is even a space for dozens of runes, which can be used for other purposes.

And this is also the reason why the Nuclear Fission Flying Sword can be assisted by a phantom array!

"It's not that this stealth nuclear fission flying sword is new to my idea, it's just that my flying sword just meets the conditions for its appearance, so that it can be turned into a real thing today, the humane civilization has been vast for five thousand years, and there is no shortage of monks with wonderful ideas, but unfortunately, sometimes it's not that the idea can't work, it's just that cultivation is not enough, and the rune array is too restrictive. ”

Shaking his head and wiping away the strangeness in his heart, Xia Chao looked at him with a certain gaze and said with a smile: "Lecturer Su, now, you shouldn't have to choose to quit, right?"

Su Yun pursed her lips and chuckled, and said, "Naturally not, next, I will ask Xiaoyou to carry me more." ”

Hearing this slightly ridiculous words, Xia Chao was humble, and his heart was slightly relieved.

With the approval of this Phantom Array Master, I think that this idea can indeed be realized.

However, when he informed Xu Zhengyang and Professor Yan Bai of the idea of the Invisible Nuclear Fission Flying Sword and wanted to ask for specific opinions, the two did not have much joy.

On the contrary, Xu Zhengyang's face moved slightly, as if he was groaning, while Old Professor Yan Bai was staring, and his eyes were faintly flickering.

Looking at the expressions of the two, Xia Chao's heart suddenly sudden, and his emotions couldn't help sinking, and he asked, "Mentor, professor, dare to ask if there is anything wrong with this idea?"

"The problem is not a problem, and the idea is good. ”

Xu Zhengyang was the first to speak, and the solemn look on his face never dissipated, "It's just that the price is a little bigger." ”

"Yes, it seems that Professor Xu is the same as I think. ”

Old Monk Yan rubbed his temples lightly with his fingers, and said slowly, "On top of the nuclear fission flying sword, it is possible to attach a phantom array, but it is okay, but this is limited in the middle-level flying sword formation diagram, and there is not much development in the past, that is to say, we are the pioneers of this array of diagrams, and everything has to start again." ”

"As a result, a lot of money is consumed. ”

Xu Zhengyang took over the topic with a tacit understanding, and said: "Regarding this nuclear fission flying sword, we are sure that it is different from any known flying sword, so it must be practiced from scratch, the material of the flying sword, the mode of operation, the operation channel, etc., etc., everything has to start from scratch, and the cost will be extremely huge. ”

Hearing this number, Xia Chao couldn't help but breathe.

100 billion investment!

Such a huge number, not to mention money, even if it is 100 billion tons of stones, it is worth a lot of money!

"Are you sure you want to apply the Stealth Nuclear Fission Flying Sword now?"

Old Brother Yan's eyes burned, and he asked softly.

This whisper was like thunder falling, waking Xia Chao up from his stunned mind, he was silent for a few seconds, suppressed many mental waves, and suddenly said with a smile: "100 billion is 100 billion, I took it, and I asked the tutor and Professor Yan to bother." ”

Xia Chao already had a determination in his heart.

This stealth nuclear fission flying sword will definitely be developed.

This matter is a matter of one's own spiritual path, and no matter how much it costs, you must do your best to reach the limit.

As for the matter of money, although it feels a little urgent, but when it comes to this kind of thing, there is no way, it really can't be done, it's a big deal to borrow from other forces, with his reputation, presumably the 100 billion funds should be fine.

"To be honest, I don't want to owe money to others, especially this huge wealth, borrowing once, even if I can return it, it is equivalent to owing a favor. ”

Xia Chao shook his head secretly, thinking in his heart: "Hey, it's difficult to have two ways in the world, and you have to pay a little price." ”

Hearing what the young man in front of him said, Xu Zhengyang and Old Monk Yan glanced at each other, and suddenly said with a smile: "Things are actually not as difficult as imagined, and there is still room for relaxation." ”

Xia Chao looked stunned, and couldn't help asking, "Mentor, dare to ask you what do you mean by this?" ”

Xu Zhengyang laughed and said, "After research, your nuclear fission array flying sword, we have decided that it can be sold for two things." ”

"Two for one?"

"Yes, it's two things for all. ”

Xu Zhengyang smiled and said, " Your nuclear fission array is overbearing, but correspondingly, the requirements for mana and divine thoughts are also very high, and if you want to drive, you have extremely high requirements for monks, so we can divide the nuclear fission flying sword into two kinds, one is a low-power nuclear fission flying sword, the specific number of runes is about two hundred to three hundred, for ordinary Daoji monks to use, and the other is a high-power nuclear fission flying sword, the lethality is developed to the extreme, we can first develop a low-power nuclear fission flying sword, make it in a short period of time, and then sell it, with the harvest of this magic weapon, to support the development of the high-power nuclear fission flying sword。 ”

Hearing this, Xia Chao's heart was shocked.

How can it still be like this? )
