Time was ticking, and seeing that the first green smoke had already burned halfway, some of the candidates began to operate with them.

Tianxing carefully recalled the liquids he had been exposed to in the past three years, and unfortunately, none of them coincided with the memories on the desktop.

The change of bronze is like a small drop of water, into the sea, without the slightest wave,

What to do next, no one told her, it seemed that this exam was a new test for refiners.

Helplessly, he patted his little head and looked at the previous methods in his mind one by one, but he still didn't have any ideas.

The unknown world, people are always afraid of it.

The challenge that has never been there, the same requirements, and the seemingly same materials, at this moment, a strong desire to fight rose in Tianxing's heart.

In the past three years, she has taken every subject seriously and studied hard.

Others only saw the glory of her first place in the exam, and who knew that she was busy with her studies all night.

Tianxing's talent is good, which is reflected in the fact that no matter which tutor's class she takes, she can not only digest it on the spot, but also draw inferences from each other to raise her doubts.

But no matter how good the talent is, it is just God's love for you, how can Tianxing, who has been self-reliant and self-reliant since childhood, be satisfied with this.

In front of everyone, she was reading and thinking.

In a place that everyone can't see, she is studying and cultivating.

Therefore, the cultivation of tenacity from an early age made her even more unyielding in her later study and life.

Take this instrumental exam as an example, as time passed, some candidates moved their hands and discovered the abnormality in it.

But the result is that their perception is broken, and they waver, retreat, and don't know what to do.

And Tianxing, after a short thought, once again picked up the bronze block and began her experiment.

"If there is no way, I will find a way out of it, and if there is no way, I will create a way out of it myself. ”

The scrappy Sky Star noticed that after a brief immersion in the unknown liquid, the weight and volume of the bronze block had changed slightly.

"It's small, it's light, it's not obvious, but when you hold it in your hand, you still feel it. ”

I don't know why this change happened, but the only difference that caused it was the liquid.

Does that mean that the liquid can make the bronze block smaller and lighter without being tempered in a furnace?

With the first guess, Celestial Star experimented.

The bronze with the bubbles on the surface was put back into the basin and watched as it changed.

Sure enough, I saw that the surface of the bronze block was constantly bubbling with small bubbles, as if the pot was heated on the stove, gurgling.

Then, the bronze block grew smaller at a rate visible to the naked eye, and instead of the small uneven holes, the surface was replaced by small pits.

The small bubble came out of this small pit, and the more bubbles, the stronger the smell became, and the sour smell that needed to be felt before was now filling the entire confined space of the exam.

Tianxing's brows furrowed, and he watched the change motionlessly, and when he saw that it had become smaller, instead of relaxing, his heart had a kind of doubt.

Do you just let it bubble up like this?

Finally bubbling to the powder, is it?

This is not the style of Tutor Qingshu, and it will not be simply used as the content of the exam.

While Tianxing was thinking about the mystery inside, the frequency of the bronze block in the basin bubbling decreased, and within a few breaths, the bronze block was completely still.

It did look half the size of the water, and Celestial took it out of the water.

This feel is also a lot lighter.

But it has not changed, does it mean that the liquid has no effect on it?

So what's next?

Throw it in the fire?

Put salt in it?

The star was thinking of something, or somehow, that would work for it again.

......

Knowing that the examination was carried out smoothly, the mood of the candidates was from the secret joy at the beginning, to the incredible at the back, and then to the doubt of life, which can be described as "a wave of unsettled, a wave of rise".

And the four people gathered at the gate of Qinghe Zhenren Cave Mansion were also discussing their senior sister's new ideas.

Qingyuan said, "Senior sister is too bad, is it too bad, she actually used this method in the exam, or is it an annual exam?" When this exam is over, I think she will have another title." ”

Qing Yuan was curious, "What title?"

"Mentor Thanos. ”

"Hahaha. ”

"Hahaha. ”

Qinghe's hand drinking tea also shook, and the corners of his mouth smiled helplessly.

Qingyuan said seriously, "In the past, as soon as Senior Sister Qingshu made a move, she knew if there was any, but now Senior Sister uses her brain, and she doesn't have any of them." ”

Qing Yuan shook his head and smiled, "Senior brother, you are too exaggerated, Senior Sister's method is indeed a new discovery, breaking through our conventional thinking, and shortening the time of refining weapons by half, and the final product has also improved by several grades, we should study hard." ”

Qingyuan rolled his eyes directly, "Senior brother, I didn't say that Senior Sister's method is not good, Senior Sister has been tossing out of all those new methods for so many years, which one is not good, I'm talking about this exam, the exam, this is the annual exam!"

Qing Yuan also reacted at this moment, and said worriedly, "The third senior brother means that this method of the senior sister is too difficult, and those candidates will,"

Qingyuan bowed his head and said, "That's right, that's what I mean, two senior brothers, junior sisters, think about it, in the past, senior sisters invented some new refining methods, which one is not to let those disciples try it first, and after everyone is proficient, it will be useful and popularized."

You see, now, yes, the senior sister has invented a new method, but she didn't say what the new method was, and second, she didn't teach these students how to do it.

That's it, give something and let them figure it out for themselves, how do you think these students will be?"

Qinggui also had a hint of concern, "This, Senior Sister should have her plans, since she can get it out for the exam, she must be able to." ”

Qing Yuan didn't bother to pay attention to this second senior brother of wood, and ran directly to Qinghe Zhenren, and said with a smile, "Hehe, senior brother, senior sister was taught by you, do you think she will be wiped out in this exam? ”

Taking a sip of tea in a cup, Qinghe said lightly, "Qingshu has his own way of doing things, he is not an unreasonable person, this exam can change the new question type, and it is approved by other class tutors, it makes sense."

Moreover, Qifeng does not need to be an immutable disciple, and this exam is also a good opportunity. ”

Qingyuan nodded hurriedly, "Yes, yes, Senior Sister, Senior Brother, you taught it personally, and there will definitely be no problem."

It's just Senior Brother, will anyone find out about this new method? Wouldn't Senior Sister be a little more difficult?"

Qinghe Zhenren smiled lightly, "It looks very big, but in fact, Qingshu has reduced its difficulty."

You see, some other things that are not within the scope of the exam do not appear at all, and she also replaced this crucial water with sour water, which is only a change or two in the usual technique, and there will naturally be results. ”

Qing Yuanjian also knew that he was worried in vain, and muttered in a low voice, "Senior brother, you are not worried at all, Tianxing is still there for the exam." ”

Qinghe's ears moved when he heard the sound, and he smiled lightly.

Tianxing is there to take the exam, but with Tianxing's head, will he not understand the key to this?

......

In the first class, the first green smoke had burned out, and Qing Shu was sitting above Gu Ying in the mirror and felt sorry for himself.

"Alas, today's makeup is a little lighter, if I hadn't rushed to the invigilator, I wouldn't have dressed up casually, but fortunately, this dress is worthy of it, and it looks beautiful. ”

When he turned his head and saw that the smoke of the first green cigarette had dissipated, he hooked his lips and smiled, and looked at the candidates below.

Qing Shu was in a good mood all of a sudden, these students were like wooden heads in the past, and this was a surprise for them.

It's just that Qingshu's surprise has become a fright for those students who are in a dilemma.

"Oh my God, what is this, how can this be, it wasn't like this before?"

"Did you do something wrong, no, or throw this bronze piece into the furnace. ”

"No, why doesn't this thing react at all? Mentor, are you sure you're not kidding?"

No more panicked than the other candidates, Han Xi's already indifferent face seemed to be covered with a black mist, and he made the same discovery as Tianxing when he started.

It's just that he is different from Tianxing, after throwing it into the "water basin" for the first time, he sprinkled salt, and the bronze surface seemed to have encountered something, stabbing and stinging, and suddenly the ground became unrecognizable, and finally the color was even darker than Hanxi's current face.

"How can this be? This is impossible, is it just my own problem?"

Hanxi began to doubt himself, but his methods were the same as usual, so what the hell was going on?

Is Ling Tianxing's normal, or is there a problem just like herself?

Tianxing, who was remembered by Hanxi, was doing an interesting experiment at the moment.

When she threw the bronze block back into the furnace, she found that the fire was actually a little bigger, and in a few breaths, the bronze block became fiery red all over.

The bronze block was taken out of the furnace and put it into the unknown liquid again, and the copper block reacted again, although it was not as big as the first bubble, but it was also a new discovery.

When the bubble disappeared, Skystar found that the copper block was much smaller than the first time.

The method just now worked.

Having come to this conclusion, the Celestial Star happily alternated the bronze blocks between the furnace and the unknown liquid.

Sweat from his forehead, obviously tired, but Tianxing's eyes bloomed with a different kind of brilliance.

After the tenth time, when the bronze block no longer reacted in the unknown liquid, Skystar began her second attempt at guessing.

A few grains of salt were lightly sprinkled, and the tiny grains of salt melted in the pot, and the surface of the copper block, which was only one-third of its original volume, was also stained with white particles.

"There's a situation, it's splitting. ”

Tianxing jumped up in surprise, the mentor gave them a copper block, after a few rounds of changes just now, although the volume has become smaller and the weight has become lighter, but this copper block is still a copper block.

But now, I just sprinkled a few grains of salt, and this copper piece actually cracked, like a steamed bun, and you tore it into several pieces.

"Is it the effect of salt to deform it?"

As soon as the idea came to him, Celestial Star eagerly sprinkled a few more grains and continued to observe its changes.

"Three, six, nine, fifteen,,"

The stars counted the small pieces of copper that had been fissioned from the copper blocks, and as the area of the salt contamination increased, the copper pieces also decomposed smaller and smaller.

"Powder? Do you have to sprinkle all this salt to have a powder?"

After thinking about it for a while, Tianxing decided to give it a try, and boldly put the salt shaker in his hand into the basin.

I saw that the bronze that was split into countless small pieces seemed to meet a nemesis, and it instantly became smaller, and then smaller, until finally, there was only a ball of powder left in this pot.

"It's really done. ”

A sincere smile appeared on Tianxing's face, but before she could be happy, she was stuck in another difficult problem.

How do you take out this bronze powder?

Do you just take this basin and give it to the teacher?

No, the bronze block is smelted into bronze powder because bronze is more common, and it is often used in the last step of the monk's refining, sprinkled with bronze powder, and the magic weapon looks like it is plated with a layer of copper on the outside, which has the effect of protecting the appearance of the magic weapon.

I don't know what this thing is?

Celestial Star looked at the unknown liquid in the basin and thought, the bronze powder was insoluble in it, and it was floating on the surface.

Just, how do you get this out?

Hand fishing?

looked at the gloves he was wearing, the heat resistance was good, but after all, it was still his hands, Tianxing shook his head, his hands were not sieves, they were fishing, when did they have to fish?

Why don't you put it in this furnace with a basin?

Tianxing remembered the scene when her mother stewed rock sugar pears for her in the Ling family, and the water would disappear when she put it on the stove, so is this liquid the same?

As soon as he said it, Tianxing carefully placed the liquid in the stove where the fire was at its highest, and crouched down to see if it could disappear like water.

Time was passing imperceptibly, and only a third of the second green smoke was left, Qing Shu put away the mirror and strolled down to look at the exam results of these candidates.

"Tsk, that's stupid, there's obviously something wrong with this water, what's the use of patronizing and looking at the copper?"

"Well, don't you know how to work around? If you become black, sprinkle some salt, isn't it the same way before?"

Qing Shu judged her students one by one, sometimes scolding, sometimes sighing, the original smile disappeared, and her face was full of depression of hatred and steel.

"Why don't they know how to adapt and try again? They always want to use the methods of their predecessors to refine their tools, and they don't know how to improve or innovate at all.

The current immortal cultivation world is no longer the previous immortal cultivation world, but these people are still taken for granted in their bones, alas, they are really regressing more and more. ”

Speaking of the back, Qing Shu was lonely for a while, not knowing whether he was worried about the stagnation of these candidates or the stagnation of the immortal cultivation world.

After reading almost all the candidates, Tianxing was left alone, Qing Shu took a deep breath, looking forward to this little nephew being able to make him happy.

When I looked closer, I said, "Hey, what is Tianxing doing?

。
