Great Swordsman

Chapter 166: The Spirit Gourd Against Mathematical Problems Is Born!

Li Mu has encountered many problems of chicken and rabbit in the same cage, but with the addition of three-legged toads and five-legged pigs...

For some reason, Li Mu sensed a vague female punch from this question.

He looked at Mo Changxing suspiciously, and couldn't believe that the other party would ask such a question.

Even if you get a three-legged swan, a five-legged crane is more acceptable to me.

"Brother Li, isn't it too difficult?" Mo Changxing smiled, but he was quite annoyed in his heart: Why did you write down the title that the second sister teased me word for word, three-legged toad and five-legged pig, it's true. But I also blame my father, thinking about marrying my second sister every day, hey.

I hope Brother Li will not give up on himself.

"Difficult?" Li Mu frowned, and smiled. To be honest, this question was placed in the previous life, and it was at the sixth grade level at most!
Don't look at two-legged chickens, three-legged toads, four-legged rabbits, five-legged pigs, thousands of heads, more than 3000 legs, and all kinds of bells and whistles, it's actually a quadratic equation, simple and tight!
Li Mu took the pen and paper, and set the chicken, toad, rabbit, and pig as x, y, z, and q.

So the question becomes:

X+y+z+q=1053
2x+3y+4z+5q=3492
among them,

x=2y
z=3q
Substituting the following two equations into it, we get:
3y+4q=1053
7y+17q=3492
It will be even easier afterwards, as long as the first formula is substituted into the second formula, it will be obtained quickly:
y = 171
q = 135
Therefore, x=342 z=405
After finishing writing, Li Mu spit out his spiritual power and shook the paper into dust.

Mo Changxing looked at it and thought that Li Mu couldn't answer the question and gave up on himself, so he smiled gently and said, "Brother Li, why is this? In fact, this question is really difficult. It was my second sister who made things difficult for me. When I first came into contact with When, also..."

Second sister?

Li Mu immediately grasped the focus: It really was a woman who asked the question!
Pooh.

In this life, I will never live with female boxing... Li Mu snorted, "I've already answered it."

"Brother Li, if you can't answer, you, you... hmm?" Mo Changxing suspected that he had heard it wrong.

When he first encountered this problem, it took him half an hour to solve it. How could Li Mu solve it in less than half a cup of tea?
I am the second younger sister, and the second younger sister is me... Mo Changxing suppressed the shock in his heart, and smiled, "What is the answer that Brother Li came up with?"

"342 chickens, 171 toads, 405 rabbits, and 135 pigs." Li Mu sneered, "Brother Mo, my answer is right."

"This..." Mo Changxing looked at Li Mu in disbelief: Has the real solution been found?

How can it be? !
There are thousands of debate questions, and it takes several sheets of paper just to write them. He just writes and draws on a small half of the paper, and then he solves it?

impossible!
Absolutely impossible!
Mo Changxing's heart skipped a beat: "Brother Li, could it be that you and my second sister..."

"I come from a poor family, but I can't compete with the Mo family." Li Mu snorted, "If brother Mo refuses to accept it, he can ask another... similar question."

Li Mu didn't dare to underestimate ancient mathematics. Since Mo Changxing created the chicken and rabbit in the same cage, of course he had to confine this question to this cage.

Mo Changxing struggled with half the salary, gritted his teeth and said, "No need."

If Li Mu really knew Second Sister, then he would find out when he went home and asked, and the earth evil spirit lost at that time would be on Second Sister's head.

Ah!
The second sister treated me like this before... Mo Changxing smiled again, and said, "Next, let Brother Li come up with a question."

"okay!"

Li Mu had no paper in his hands, so he directly used the sword to write on the ground.

You give me a sixth grader, and I'll release the water, and I'll give you a third grader!
So, he really released the water:
A pool has two upstreams, A and B, and one downstream, C. A can fill the pool in twelve hours, B can fill the pool in sixteen hours, and C can drain the water from the full pool in fifteen hours. , Excuse me, after the two upstreams of A and B are opened for six hours at the same time, B is cut off, and C is opened to drain water. Excuse me, after how many hours can the pool be filled?
Mo Changxing looked at the title and became a Muggle.

This question...is really a bit...scalp-numbing!
It's even more outrageous than the chicken and rabbit cage question that the second sister made difficult for him!

"Brother Li, this question..." Mo Changxing asked himself that even if he could solve it, it might take an hour, but Li Mu solved his problem in less than half a cup of tea.

It's a verdict, the outcome... has been decided!
However, Mo Changxing was a little dissatisfied after all: "Brother Li, this problem is so complicated that it won't take an hour to solve it."

The implication is that the questions I asked are simpler than yours, which is unfair!
"Really?" Li Mu sneered, and directly converted on the ground.

设整个水池的水为单位“1”，则由题可知甲速度为1/12，乙为1/16，设再过y小时注满水池，则可列出方程6*（1/12+1/16）+y(1/12-1/15)=1 。

Li Mu pointed like a sword, calculated quickly, and finally solved y=7.5.

His answer is faster than counting Mo Changxing's chicken and rabbit in the same cage!

Because Li Mu's problem can be solved with only one linear equation in one variable, but Mo Changxing's problem requires two linear equations in four variables, and they have to be substituted in. Substituting in is troublesome!
Therefore, the time for Li Mu to solve his own problems is even shorter!
At that moment, Mo Changxing felt that his head had grown bigger.

"Brother Li, what do these symbols you wrote mean? Seven and a half hours, is this really the final answer?" Mo Changxing felt that Li Mu was fooling himself, and felt as if he had discovered the door to a new world.

Li Mu smiled and said, "If you don't believe me, why don't you ask a similar problem, and I can still solve it!"

Mo Changxing thought for a while, and immediately imitated the second sister's practice. On the basis of Li Mu's question, he added an upstream and a downstream, and marked the time when the pool was filled and emptied.

Li Mu took a look, and still solved the correct answer in a very short time.

Mo Changxing frowned and said, "Brother Li, are you trying to lie to me?"

Don't look at just adding an upstream and a downstream, but the number of variables increases, and the difficulty of solving problems can be said to rise linearly.

Just like chickens and rabbits in the same cage, if there were only chickens and rabbits, Mo Changxing would be able to get rid of them in a few breaths, but with three-legged toads and five-legged pigs, he would need half an hour!
He felt that Li Mu was probably fooling him!

"If you don't believe me, you can give it a try!" Li Mu suggested that he go home and dig a pool by himself, make three upstream and two downstream, and then slowly test it by himself.

"Okay!" Mo Changxing responded directly and loudly. The pursuit of the debate is the absolute truth, and there is no room for ambiguity. Mo Changxing practiced the debate, so he naturally wanted to find out the truth!
He said: "If the answer is as explained by Brother Li, I will lose two of your Earth Sha Qi, plus the other compensation, a total of three! If I win, Brother Li will still get one of the Earth Sha Qi from my Mo family, But I can also get Brother Li's Sha of Thunder!"

"It's a deal!" Li Mu and Mo Changxing clapped their hands together as an oath.

"Being friends with Brother Mo is really a great joy in life!" Li Mu was full of emotion.

But Mo Changxing shouldn't, he looked at the question on the ground, carefully remembered it in his heart, and tried it immediately when he got back!
"Brother Mo..." Li Mu was still about to say something, but out of the corner of his eye, he suddenly caught a glimpse of a beacon rising into the sky in the distance!

……

Outside Qingping County.

Around the Li Mansion, dozens of monks wandered around and surrounded him.

Farther away, there are more monks watching!
Lin Youjing, Hua Jieyu, groom, Zhang Long and others scattered around Li's mansion, confronting this group of people through the five-color aura barrier.

Han Qingqian set off beacon smoke in the backyard, and Ginseng Doll, Hu Dundun and Little White Horse were also there.

"Everyone, if you besiege the official residence of the imperial court, aren't you afraid that Jiutian Yingyuanshen Mansion will punish you?" Seeing that the smoke of the wolf had been lit, Lin Youjing poured spiritual energy into his throat and asked all the cultivators in a sharp voice.

He has already taken the Congealing Flower of Emperor Flowing Syrup, and even though no flower has condensed yet, white flowers have already appeared on his chest and abdomen, and he has made great progress in his cultivation.

His voice was filled with golden awe-inspiring righteousness, and the sound waves rolled over. Many monks with distracting thoughts were shocked by the awe-inspiring energy, and their mood fluctuated.

"Qingping County Magistrate Li Mu brutally killed the four housekeepers of the Mohist family and hunted down the youngest of the Mohist family. His actions are heinous. I will act in the heaven's behalf and kill Li Mu!" A romantic young man waving a folding fan said calmly, "This time, only the chief villain will be punished. People in the Li family, don't shut down the formation quickly!"

"That's right, Li Mu has made a big mistake, and death is inevitable. Do you want to go to hell with him?" Another monk sneered.

As for Jiutian Yingyuanshen Mansion, heh, as the monks in various counties become stronger and stronger, there are more and more disputes and killings. The world of contention is coming, and a mere Nine Heavens Yingyuanshen Mansion can handle it?

What's more, the situation in the court is changing. One moment, the Jiutian Yingyuan Shenfu dominates the holy family and looks down on the big cadres. The next moment, the Hanlin Academy and the Guozijian are all together. What is the Shenfu?
Hua Jieyu's beautiful eyes narrowed slightly. Seeing that Lin Youjing couldn't hold back all the cultivators when he carried out of the shrine, he planned to move out the master of Shenqing temple and the abbot of Bailong temple. The upper six people have directly become influential figures, looked up to and respected by countless monks, and practice hard with this goal in mind!

But before she could open her mouth, she saw a ray of purple light suddenly rising from the backyard!

"What's that?" Seeing the purple light, the ginseng doll ran over excitedly on her short legs, and it turned out to be a purple gourd!
"It's so mature at this time..." Han Qingqian was startled, she looked around the monks outside the backyard, one by one, all of them looked greedy.

They didn't encircle the mansion for the Mo family at all, but for this gourd... Han Qingqian realized something, and hurriedly reminded Lin Youjing and others!
"My, mine, the gourd is mine~" The ginseng doll's fat face was bathed in purple light, and she jumped up and down to pick the gourd. Unfortunately, she was too short, less than fifty centimeters , bouncing in place there, unable to reach the gourd at all.

After a while, the purple light on the gourd gradually disappeared.

As the breeze blew, the purple gourd swayed slightly, and its vines suddenly split open with a click, and the whole thing fell off, just in time to fall into the arms of the ginseng doll.

"Hahaha, it's mine, it's mine~" Ginseng Doll was overjoyed, holding a gourd bigger than her head, running around under the gourd stand, so excited.

"The spirit treasure is born!"

"That purple light is so pure that it soars to the sky, it really is not an ordinary treasure!"

When the dozen or so monks around the backyard looked at each other, they all saw greed and ruthlessness in each other's eyes.

The next moment, they all shot together!

Boom boom boom...

Various spells fell on the five-color aura shield like fireworks.

The shield rippled and quickly counteracted the spell, but as the purple light soared into the sky, the monks surrounding the rest of Li's mansion also came against the wind, attacking frantically!
Lin Youjing and the others changed their expressions and hurried to the backyard.

At this moment, forty or fifty monks shot out outside the aura shield in the backyard, and countless ripples rose and fell on the shield. It can be seen that the five-color aura on it is getting weaker and weaker!

"Prepare to fight to the death!" Lin Youjing stood in front of everyone with a spear in his hand.

Groom Yang Ma, watchman Xu Tong, Wu Zuo Song Dian, Ku Ding Zhou Cang, Zhang Long Zhang Hu, Liu Qi and Deng Yan are holding bronze knives, their spiritual power is pouring into the knives, and the blue light is overflowing, ready to trigger a big battle of retribution at any time !
Hua Jieyu's robe fluttered, and the white silk in his hand was automatic without wind.

"Aww~" Hu Dundun stood at Han Qingqian's feet, and roared childishly at the monks outside the shield.

The little white horse hid under the bamboo brook gourd trellis, trembling and trembling.

"What are they going to do?" Ginseng Doll hugged the purple gourd, blinked her big eyes, and looked at Han Qingqian puzzled.

"They want to kill people and seize treasures." Han Qingqian said, "Baby, if you hold the gourd, you will become a target of public criticism. Give the gourd to me."

"No, it's me~" Ginseng Doll hugged the gourd tightly, refusing to let go no matter what.

Yazi knife... At this time, outside the shield, a man with sword eyebrows and starry eyes raised his brows, looked at the bronze knife in the hands of the groom and the others with a face full of surprise, "This trip is worth it!"

He softly instructed his subordinates to snatch all the bronze knives in the hands of these eight people later!

Afterwards, he circulated a flower and five qi, and said in a low-key and righteous voice, "This formation should be broken!"

In the next moment, the already overwhelmed five-color aura burst instantly!
"Quick!" The man shouted, and shot away in an instant, heading straight for the ginseng doll.

"Iron Horse Glacier!!" Young Whale Lin was already ready and stabbed with his spear.

The gun light bloomed brightly, and the terrifying iron blood killing intent was as cold as ice, locking the figure.

"Little Qingping County, there is such a shooting." The figure sneered and shot, "Thunder is born on the ground!"

boom! !

A purple thunder rose out of thin air, and exploded in the courtyard at a very high speed, forcefully blasting a gap in the spear light of Lin Xiaojing!
The man's figure flickered, he had already passed Lin Youjing, and stretched out his hand, the spiritual power swept across, and the ginseng doll holding the gourd flew towards his palm in its entirety.

Only then did everyone see the face of this person clearly.

Sword eyebrows and star eyes, long hair flying, dressed in white, suave and romantic!

"Baby!" Hua Jieyu reacted very quickly, and the white silk in his hand wrapped around the feet of the ginseng doll in an instant.

"Mine, mine, you are not allowed to snatch it~" The ginseng doll glared at the man in white, baring her small white teeth fiercely.

"Let go!" Lin Youjing was frightened and was about to turn back when forty or fifty monks outside the backyard had already killed them and fought with the eight grooms.

With outnumbered enemies, even if the eight grooms resorted to a large array of retribution, they would not be able to cover so many people. They were about to be taken away by a wave. Lin Youjing had no choice but to go to the rescue. Said, "Let the doll let go!"

There is only one spirit gourd, and everyone is inseparable. Once it falls into their hands, they will definitely kill each other!

It's a pity that the ginseng doll is very stubborn, gnashing her teeth and refusing to let go no matter what she said: "I da I da~~"

Although she is small, she is quite strong, the man in white couldn't take the gourd from her hand for a while!
"Gourd, quickly grab the Lingbao!!"

"The one in white, get away with me, the gourd belongs to me!"

Lin Youjing and the groom couldn't stop so many monks at all. In just a few breaths, more than 20 monks came over against the wind and killed the ginseng doll.

"Baby, let go!" Hua Jieyu used the white silk to hold the ginseng doll, but he couldn't pull out his hand to resist these monks.

Even if she makes a move, she can't stop her with her current cultivation!
"Baby!!" Han Qingqian hurried over, trying to break the baby's hand.

However, the ginseng doll hugged the gourd tightly, and looked at Han Qingqian with big and round eyes stubbornly: "I am the gourd~"

"You're so greedy at such a young age, huh." The white-clothed man sneered, and was about to kill him, when suddenly a chill came from the back of his head, making his hair stand on end!

He raised his head abruptly, and saw heavy rain above the sky!
Those are not real raindrops, but countless sword qi, densely packed and colorful, converging into rain, like a galaxy rushing down, gorgeous and dazzling!
