Among the universities.

Thousands of Tianjiao paid attention to the changes in the credit list of the monthly competition, and there were wisps of confusion in their hearts.

The number one credit seems to have not been touched for a long time.

Since one o'clock in the afternoon, Xia Chao's credits have stayed at two hundred and thirty-five points, and there has been no upward trajectory.

His score froze.

This is not normal.

Very abnormal!

With the momentum of the sudden advance before the teenager, he can swipe nearly two hundred points a day, and the momentum is like a wild horse that is rushing wildly, sprinting forward all the time, and it seems that it will never stop.

But, suddenly, the mustang stopped and stood still.

This contrast between extreme movement and extreme stillness made many Tianjiao wonder, not knowing what Xia Chao was thinking and doing.

That's not right!

What is the reason why they can make a big credit and improve their ranking to a level that is difficult for them to achieve, but they suddenly stop?

In the face of the boy's abnormal behavior, everyone had a feeling that the second monk was confused.

Among them, the one who feels that things are weird the most is Zhao Chaoying.

She originally wanted to find Xia Chao to test each other and practice martial arts, but suddenly, she couldn't find anyone.

"Where the hell did this boy go?"

Under the sun, the sword-eyed girl frowned, and bit her lower lip lightly.

......

"After all, I'm just a teenager, and I'm in the middle of it. ”

Thinking at the change in the monthly competition credit list, Professor Xiao was slightly happy in his heart, and the corners of his mouth hooked up a trace of arc.

His eyes were already slender, like two diamond-shaped willow leaves, and with a smile on his face, his eyes narrowed slightly, making him even more narrow.

His premeditation succeeded.

Just now, he used the phantom array to yin the summer tide once. Before leaving, he sneered, on the surface, it was to vent his dissatisfaction, but in fact, it was to arouse the anger in the young man's heart and let him and Xu Zhengyang get together. Study the Dharma.

As long as Xia Chao develops a magic weapon, it must be a waste of time!

"Hmph, how can you succeed in researching magic weapons so easily?

"Isn't it said that he is a small Qi Induction Realm cultivator, and the powerhouse who is connected to the Dan Realm does not dare to say that he can easily create a new magic weapon, even if it is only for the Qi Induction Realm monk, because there are too many things to consider, the structure of the formation diagram, and the materials of the magic weapon. The number of arrays, blah blah, it's too complicated, what can you make in just thirteen days?"

"I've seen the explosion of the disc before, and it's indeed a bit unexpected, but what you can't control is useless. In such a short period of time, there is absolutely no way for him to achieve results!"

"And this. It also means that this teenager will be wasted for more than ten days. ”

Professor Xiao stretched out his hands and crossed them in the shape of ten fingers, and his dark pupils were deep.

"Tianyun, this is the best opportunity I have created for you. You must take advantage of the spare time of these ten days, you must work hard to earn credits and strive for the first place. ”

This man is scheming. It's come to this point!

Speaking of which, as a powerhouse of the Jie Dan Realm, to calculate a Qi Induction Realm cultivator, no matter how you say it, the means are too despicable.

It's just that......

"The world is often so cruel, I am unscrupulous, that's why I can be the final winner!"

On the other side, Xia Chao is progressing extremely fast.

With the direction of the extension of the magic weapon, and the help of the three powerhouses, in just five days, he tested a suitable induction explosion array, and the development speed can be called the speed of light.

On the sixth day, they began to study the magic tools of the formation diagram.

In this regard, Xia Chao thought very simply.

It is impractical to use this explosion array as the core to create a new magic weapon, and this array can be directly put on the array disk and used as a mine.

And this idea was quickly recognized by the other three powerhouses.

In this way, all the difficult and complicated steps of creating the magic weapon are eliminated, and the whole process is already extremely simple.

All that's left is to find the right materials for the artifact.

Originally, the array disk used by Xia Chao was extremely suitable for the explosion array, but there was no perfection, only more perfect, in order to reduce costs, and in order to achieve a certain advantage in comparison with the achievements of other professors, it was natural that more experiments were needed.

In this regard, the summer tide does not matter.

At this point, his work was almost complete, and when it came to the level of understanding of the various array materials, the powerhouse of the Yudan Realm knew far more than him, so there was no need to waste any more mental consideration, as long as he looked at it with a learning mentality.

Although this kind of simple learning can't get any credits, in his opinion, the sparks of the collision of the thoughts of these strong people in the Dan Realm are far more important than the credits.

And the next division of labor, as in the past.

The three of them were still in charge of researching the materials, while Qi Zhaoxing continued to test his power.

These days, all the array tests have exceeded 3,000 times, and they have been carried out on Qi Zhaoxing alone, and now the array will be put into the array, so the power of the explosion will skyrocket.

Thinking about the explosion of this burst, Xia Chao sighed softly.

Looking at Qi Zhaoxing's weather-beaten numb expression, he shrugged his shoulders and closed his eyes.

He couldn't bear to see what was next.

......

In the midst of the booming explosion, research broke through at a rapid pace.

One difficulty after another appeared, but it was easy to solve, and after six or seven days, finally, the induction explosion array disk was officially released!

It was an oval disc.

Its appearance is no different from other array disks, there is no difference, but there is a faint rune mark on the edge, if you want to use this disk, you only need to enter a little mana into the rune mark, and the array disk will be officially activated in a minute, sensing the traces of all living beings within a radius of ten meters, once a strong person steps into the array within ten meters, the array disk will be instantly detonated!

At this point, the entire explosion weapon has been declared a success!

Although the prototype is a formation disk, in essence, there are still some differences between this magic weapon and an ordinary array disk, so it is necessary to take a new name for the magic weapon.

And the three powerhouses of the Dan Realm agreed in unison, and together they handed over the right to name the magic weapon to Xia Chao.

After hesitating for a few seconds, Xia Chao had a little bad taste in his heart, and then spoke.

"Call them landmines, what do you think?"

Unexpectedly, the three powerhouses agreed with the name.

"Good name, this magic weapon is buried in the ground, and the sound of thunder erupts, the name of the mine is indeed very suitable!"

"Landmines, that's a fitting name. ”

"I think it's good, too. ”

Under the joint nod of the strong, the first mine in the other world was officially born.

Looking at the cold edges and corners of the mines, Xia Chao was secretly satisfied in his heart.

This kind of disposable magic weapon has small requirements for use and low price, and I believe that the humanitarian government will definitely pay attention to this, so it should suppress that Professor Xiao's innovative magic weapon, right?

He is extremely disgusted with the other party's dirty methods of using yin tricks, if he can't get justice from the front and completely overwhelm the other party, I'm afraid that for a long time, his mood will not be beautiful.

However, when he looked at Xu Zhengyang and asked about the prospects of this magic weapon, Xu Zhengyang's response was like this.

"There is a prospect, after all, the use requirements are small and the cost is low, but if it is said that it can make the humanitarian government put most of its mind on this side, there is little hope, because the killing range of fifty meters is still smaller after all, with the reaction speed of the strong people in the Dao Foundation Realm, it may not necessarily be able to hurt, to be honest, it would be good if it could pull hundreds of millions of profits, it is estimated that it is still not as good as the magic weapons developed by other professors. ”

This answer made Xia Chao feel cold in his heart.

If this mine can't suppress Professor Xiao's side, then how can he express the depression in his heart?

Do you really want to endure this depression like this?

No way!

He must find a way to increase the range of mines!

However, in two days, the humanitarian government will send someone to inspect it, so where will he have time to continue his research?

Xia Chao couldn't help but be a little anxious.

If he could not overwhelm the results of Professor Siu's experiments, although he had gained a lot in these days of hard work, he still left a trace of regret that was difficult to complete.

How can I increase the range?

His mind was wandering, looking back at his past memories, trying to find a relatively sketchy solution.

After thinking silently for a moment, Xia Chao had a flash of inspiration in his mind and slapped his thigh suddenly.

"By the way, there's a ready-made example, what else do I think about? ”

He immediately approached Xu Zhengyang and said that he had an idea that could increase the lethality of the mine, Xu Zhengyang was shocked and motioned to Xia Chao to speak directly.

Just listening to Xia Chao say two or three words, Professor Jiedan Realm's eyes slowly lit up.

Xu Zhengyang laughed, couldn't wait, and hurriedly beckoned Qi Zhaoxing and said, "Assistant Teacher Qi, we still need to do an explosion test, please help me test it!"

As soon as he heard this, the corners of Qi Zhaoxing's mouth twitched.

Because the joy of the successful development of the mine immediately faded, and his expression suddenly became numb, as if in an instant, he had experienced hundreds of years of vicissitudes.

He nodded, and answered a word simply and clearly.

"Good. ”

There was an inexplicable sadness in his tone. (To be continued.) )
