Obligations of the elderly

It was very quiet in the classroom.

No one is talking to each other, everyone is poring over the mold in front of them, occasionally watching everyone else's progress out of the corner of the eye, and beyond that, no one wants to try it first.

As high-level users, everyone is unwilling to show their shortcomings in front of others.Presumably, students with higher grades tend to be more cautious in each exam, especially in front of other students with good grades.

In the end, everyone's peripheral vision... No, it's not peripheral vision anymore, and everyone's eyes fell on Xiliu.

Ignoring what they were thinking at all, Xiliu carefully studied the mold in front of him.

Under everyone's gaze, Xiliu stretched out an index finger of his left hand, lightly tapped on the leftmost tube, and a stream of black energy drilled in finely and densely!

Then--

There were two crisp sounds of "click" and "click", and the pipe on the left shattered.

Raising his eyebrows, Xiliu tapped the second pipe on the left again, "Kacha Kacha", that pipe was also broken.

It's not ordinary broken, but the kind broken into powder.

There were two soft chuckles from around.

Xiliu raised his head and looked over: there were two boys standing in his direction at ten o'clock. One was tall and strong and the other was short and lean. He hummed and lowered his head, but the tall one smiled at the stream instead.

Meanwhile, on the right hand side of the stream, Nebula is also trying.

Like a stream, he also stretched out the index finger of his left hand. When the index finger touched the mouth of the left pipe, a burst of colorful energy passed through the pipe, and it only took a second to drill out from the other port. come out.

Without stopping, Xingyun immediately began to try the second and third...

Passing through four pipes in a row seemed to be an easy task for him, and he continued to try without any sweat on his forehead.

Seeing that Xingyun successfully reached the fourth one in an instant, and was about to reach the fifth one, the others stopped waiting and took action one after another.

The teaching of Ji Ling College is still very reliable. These students have successfully passed the first three channels. When passing the fourth channel, a boy failed. I bought a pipe of the same specification, and then concentrated on attacking this type of pipe.

And other people's attempts are still continuing, but then, failures gradually occurred, "click" - this is the sound of a yellow-haired girl's fifth failure; "click" and "click" - this It was the voice of the two boys who had ridiculed the stream before and failed to reach the sixth;

And when it comes to the seventh root, basically everyone has failed, except Xingyun.

At present, the only person on the round table who is still continuing the new pipeline challenge is Nebula.

Without squinting, Xingyun only saw the pipeline in front of him. He was steadily controlling the transmission of energy from his fingertips, sending it into the pipeline like a trickle, but the pipeline was basically completely black. Now, only one-sixth of it is transparent, and the structure of the pipe exposed by the transparent part is extremely complicated, the length of the pipe is only about ten centimeters, and the inner length inside is folded and folded, bent over and over again, and it may not be possible to pull it apart It's already ten meters long!It is conceivable that other positions in the pipeline should have the same difficulty.

Just as the middle-aged man said, at this stage, the internal structure of the pipeline has become extremely complicated, and the entire pipeline is simply a huge maze!Still can't open the kind of eyes!The key is that the length is too long... The user must steadily control the input of his own energy. This energy input must be stable, and the unstable pipe will break; in addition, this energy must be able to adjust the input amount at any time. Because the thickness of the pipe inside is not fixed, sometimes it will suddenly thicken, and sometimes it will suddenly become thinner. What is even more desperate is that this change is irregular and very sudden!

In addition, there are countless paths in the pipeline, and among these countless paths, only one is correct and can lead to the other end of the pipeline...

It's just a simple tube. It looks very simple on the surface, but in fact it needs too many capabilities.

This kind of pipeline is a new teaching aid, which was only introduced into the college this year.For everyone here, this is a real new thing, and there may be no preview at all. The test is the degree of everyone's control over their own abilities.

When the thin stream of colorful energy slowly came out from the other end of the seventh pipe, even Xingyun was already sweating profusely.

Thin beads of sweat covered his snow-white forehead, and he continued to output energy, controlling the energy to come out of the pipe smoothly.

There was a burst of applause from around, it was other users.

No matter where they are, people will always give sincere praise to the truly strong.

The energy flow was completely drawn out, Xingyun took out a handkerchief to wipe his sweat, folded the handkerchief with his slender fingers and put it back, he glanced to the side.

There was a stream there, but in his eyes there was no stream at all.

"That's how rulers are..."

"Not as good as Nebula."

"Xing Yun is infinitely close to a ruler! There hasn't been a ruler in the past 70 years, and Xing Yun has already been regarded as a ruler!"

"That's right, speaking of which, there hasn't been a ruler in 70 years. Where did this kid come from?"

"Could it be a lie?"

There was a murmur of discussion around.

The discussion ended with Xing Yun's light cough.

With a light cough, Xingyun is ready to challenge the eighth pipe!

It seemed as if nothing had happened, but he actually took the challenge after making sufficient preparations. The energy flow in his hand was controlled steadily, and Xing Yun had to inject energy into it carefully.

After the challenge of the seventh pipe, he knows better than anyone how difficult the eighth pipe will be!

really!The energy flow guided by his fingers disappeared as soon as it entered the pipe. The pipe inside suddenly became very thick, and it was made of some kind of folded material. The pipe looked thin, but the actual capacity was far more than that!

Nebula had no choice but to immediately increase the energy output of his fingers. However, he continued to output, and continued to output. He continued to output like this for a long time, but he still couldn't fill the entire pipeline...

He had no choice but to tighten his energy flow, making these energy flows thinner and longer. He tried to use this thin energy flow to find a way out around...

Ten minutes later, the pipe cracked, and colorful energy overflowed from the pipe crack. Finally, Nebula's challenge ended.

"It's been great."

"Student Xingyun, you have been in there for so long, you should have gone in for a long distance, right? Maybe it's almost there."

"Yes, maybe you can succeed if you try again! After all, you have traveled the road ahead!"

The people around congratulated Xingyun, but Xingyun frowned, and was noncommittal to the praise of the people next to him.

Others thought he failed at the end, but only he knew: he failed at the entrance!

It was the entrance of the pipe that suddenly thickened. His energy was completely lost in it, and finally lost control and could not be stabilized, and the pipe shattered.

The little bit of sense of victory that had just come from successfully passing through the seventh channel suddenly disappeared, and Xing Yun became extremely calm again.However, at this moment, when everyone around Xingyun gathered around to watch the pipeline he was walking through, the stream next door, which had failed from the beginning, acted again.

Instead of taking a new pipe from the locker below like the others, Xiliu put his finger directly into the third pipe entrance, and a black energy gushed in from his fingertips.

The influx of energy was as fast as anyone could see with the naked eye!Most people input energy little by little, but no, the energy of his fingers is shot in like an arrow!Because the flow rate was too fast, the energy at his fingertips gradually became a thin black line.

At this speed, everyone thought that the pipe would break soon, just like the two pipes that were shattered into powder before, but no——

The third pipe was not broken, and the black energy flow quickly gushed out from the outlet at the other end of the third pipe. There was no backflow at all, and the energy was directly transferred to the fourth pipe, and passed through the fourth pipe at the fastest speed. After four pipes, the same method was used to directly twist and enter the fifth pipe, the sixth pipe, the seventh pipe? !

The seventh pipe that blocked everyone except Xingyun was easily passed by the stream!

There is no such thing as Xingyun's profuse sweating after coming out. The stream looks very relaxed, and there is even a smile on the corner of his mouth. Under the eyes of everyone, the energy comes out of the seventh pipe at a rocket-like speed, without stopping Meaning, with the momentum of a galloping horse, he plunged into the eighth pipe!

The eighth channel that broke Xingyun...

The stream passed in just 3 minutes!

He actually passed again? !

In the classroom, all the users had extremely incredible expressions on their faces, especially Xingyun, whose eyes were wide open, and Xingyun looked harder than anyone else.

He watched the black energy that passed through the eighth channel directly transfer to the ninth channel without stopping.

The legendary ninth root...

Nebula knew from the failure of the eighth channel that he would probably be trapped in the eighth channel for about a month, right?I haven't tried the ninth channel, but compared with the situation where the difficulty doubles from the seventh to the eighth channel, he conservatively estimates that he will need at least four months for the ninth channel.

And now-

A pipeline stream he estimated would take four months to pass in just four minutes...

Nebula watched as the black energy came out of the end of the ninth tube, where it was a section of transparent glass tube that went straight up to the ceiling, where there was a sphere.

He saw the sphere focused on black energy, the black energy of the stream.

"Congratulations to Xiliu for completing the project assessment this semester and successfully advancing to the next level of study."

"Congratulations to Xiliu for becoming the No.1 student in the whole continent who passed the examination of this project. I hope you will continue to work hard and continue to achieve better results~"

When the sphere was filled, a voice suddenly sounded in the classroom, a somewhat mechanical electronic female voice.

It is probably the clearance reminder of the teaching aids. This happened with the previous teaching aids, but the rankings in the whole continent... This is the first time they have heard of it... It was all the internal rankings of the academy...

Everyone couldn't help turning their attention to the stream.

Seeing that he had moved his fingers away from the mouth of the pipe at some point, the black energy inside the sphere was still accumulating, and the unattended energy overflowed from the top of the sphere and from the mouth of the pipe, and the black energy in the classroom continued to increase. The human energy was covered again, the whole classroom became dark, those black energy forms materialized, and they could even see long strips of energy bodies wandering in the air...

What a terrifying energy...

Be it those wandering bodies or those energies, they saw them slowly drifting towards the direction of the stream.

The stream surrounded by this black substance looked like a demon king in the night, and his lips could be seen in the blackness, and they heard him say:

"It seems that I don't need to see you in this class~"

There seemed to be a smile on those thin lips.

Then--

The man left with the black mist.

After the door slammed, everyone was locked in the dark classroom.

The author has something to say: Xiliu: I was bullied...

Gong Si: Who?Tell me, and I'll settle the score with him.

Stream: It's all right (I've done the math myself)
