How to break the rules?

Theoretically speaking, it is to find the core hub of the demon city formation, and after controlling it, you can break the rules.

Of course, where the core hub is, how to find it, how to use it, and what kind of conditions users need are the specific problems faced.

The demon city in front of Qin Liang had already changed its appearance.

Except for the silence, everything is as good as new.

He looked up and saw that the sky was deep and gray.

Not far in front of him, there was a wall nearly a thousand feet high, a gate was tightly closed, and a ball of light was quietly suspended under the gate.

Qin Liang and Song Shu glanced at each other. He saw a look of fear in Song Shu's eyes.

Songshu has been to this place many times. But this is the first time he has encountered this kind of situation.

"What's the situation...... What's going on...... Sir, we need to get out of here!"

Songshu has always been cautious and cautious. The best thing to do when you know that this is happening is to leave so that you don't get caught up in the risk.

"Let's go?"

Qin Liang shook his head and said, "We can't leave now." ”

"What then?"

Song Shu looked around, and saw that the familiar scene of the past had disappeared, and he almost cried.

"What are you afraid of. ”

Qin Liang said lightly: "The soldiers will block, the water will cover the earth, the sky will fall, you can block it." ”

“......”

What does the master mean to send him to death?

Hearing this, Song Shu was so frightened that tears rolled in his eyes, and he said in a trembling voice: "Master, the small man is short, and his body is not tough enough, he will definitely not be able to hold it......"

"Got it......"

Qin Liang waved his hand: "It's just a joke with you, don't be so nervous." ”

Seeing that Qin Liang seemed to be really just joking, Song Shu breathed a sigh of relief. But the world is sinister, who knows if the master is just joking with him, or if he really has this mind?

Qin Liang stared at the ball of light in front of the giant gate.

There is no doubt that the form of the demon city at this time is the most powerful state it has ever been, and if you want to enter the demon city, you must only follow the rules of the demon city.

"Song Shu, pour your divine thoughts into the ball of light. ”

Qin Liang pondered for a moment before making a decision.

"Huh?!"

Song Shu was startled, and wanted to ask why me, but he couldn't say this kind of thing after all. Didn't the old man say just now, the sky is falling, push him up first, this kind of thing to test whether the light ball is dangerous, naturally let him go first.

Of course, there is still a certain gap between the actual situation and what Songshu thinks.

This demon city only allows the demon clan to enter and exit, and they are not harmed. Qin Liang was able to mix here now, completely refining a wisp of Songshu's breath and deceiving the perception of the Demon City Formation.

But the breath can be covered, but the divine soul can't be an illusion, once his divine mind enters this place, it is likely to be counterattacked by the demon city, and there is no possibility for these two divine souls to leave.

Therefore, it is naturally more prudent to leave this matter to Songshu to do.

"Don't worry, I'm watching, nothing happens. ”

Qin Liang comforted Song Shu with gentle words, but his tone could not be refused.

"Yes......"

Song Shu trembled, gritted his teeth, pressed one hand on the ball of light, and injected a wisp of his divine consciousness into it.

Qin Liang relied on the secret technique of the forbidden spell contract to quietly monitor the activities of the Songshu Divine Soul at this time.

“...... Open the Divine Domain with the power of the bloodline, or unlock it with the key?"

A voice sounded in the depths of Songshu's divine consciousness.

"Sir...... What to do?"

Song Shu's voice sounded.

"Let's try the bloodline first. Qin Liang sent a message from his heart.

"The power of the bloodline. ”

Song Shu took a deep breath.

Immediately, Qin Liang saw that a look of pain appeared on Song Shu's face.

Immediately after, a drop of blood essence was secreted from the center of his eyebrows, slowly floating above the ball of light, and secreted into it.

A burst of colorful brilliance spread across the ball of light.

In an instant, the brilliance vanished.

“...... The power of the inferior bloodline...... Void. ”

The message sounded again in the consciousness of the god of Songshu.

Song Shu glanced at Qin Liang faintly.

He was just a poor little squirrel, and in the hierarchical bloodline system of the demon clan, he didn't enter the stream at all. If his bloodline can open the treasure city of the demon clan, it will be really weird.

"Then try the key. ”

Qin Liang also sighed. He didn't expect that the ball of light would rate Song Shu's bloodline as inferior, and he didn't know if it would hit Song Shu's self-esteem.

In the ball of light, a ruler without a scale soon appeared, and there was also a compass.

"Can I make a regular heptagon if I only use a ruler and compass without a scale? Yes, please prove, no, please refute it. ”

“...... What's the problem?"

Songshu fell into confusion all of a sudden.

He could see at a glance that this was a question involving the formation, which seemed simple, but it was not easy to answer.

"Puff ......"

Seeing this question, Qin Liang suddenly laughed.

"I didn't expect that in this world of Jiuzhou, there are such mathematical problems......"

Qin Liang patted his head, looking a little excited.

In the world where he had practiced in his previous life, this question had arisen almost before he was born.

There are many similar problems, and this is just one of them, and it is not complicated. It's not hard to solve. But after thousands of years of time, the wise men of that world have the power to solve them one by one.

The most brilliant one, Qin Liang called it Gaozi. This man used a ruler to draw a regular seventeen-sided shape.

It's just a drawing, that's it. He also gave the conditions for regular polygons that can be drawn with rulers and gauges, that is, polygon drawings that conform to that set of formula algorithms can be realized.

Of course, that set of formulas was not proposed by Gaozi, but by another mathematical genius Fermat, and some great mathematicians made further conjectures on the basis of this theorem, which was hailed as the crown jewel of mathematics.

Qin Liang had also studied this problem for a long time before ascending, and it was quite fruitful, according to Qin Liang's thoughts, if he was given another one or two hundred years, he should be able to solve it.

Of course, delving into these issues is not because Qin Liang is idle to pass the time, but more because when he delves into these problems, he can understand the Dao Zhi Zhi and the rhythm of heaven contained in them.

"Sir?"

Seeing Qin Liang laughing, Song Shu was shocked in his heart.

"Come, according to my train of thought, this ruler can't draw a regular heptagon......"

Qin Liang just sorted out his thoughts, and then imprinted the answer into Song Shu's consciousness.

"Huh?!"

Song Shu almost knelt down in an instant: "Can this problem really be solved?"

He thought that he was a great formation division, at least in the western Xinjiang, in a state of no opponent, proficient in mental arithmetic and calculation, and even more so in arranging formations.

This kind of drawing question itself is a question of studying the ability of the array master, but when Songshu has no thoughts, Qin Liang already has the answer, how big is the gap between the two?!
